Description
Technical Field
The invention relates to the field of manufacturing of vapor-deposited films, in particular to a coating liquid applied before vapor deposition, and specifically relates to a coating liquid which is pre-vapor-deposited on CPP and PET substrates and is used for improving the bonding strength of a coating layer and the barrier property of a film, and a preparation method thereof.
Background
Conventionally, barrier plastic films, which are formed by forming an inorganic film on the surface of a plastic film substrate using a plastic film as a base material, have been widely used for packaging various articles requiring barrier against water vapor, oxygen, and the like, for example, as packaging materials for preventing deterioration in the food, industrial products, and pharmaceutical industries. In recent years, barrier films have been widely used in industrial fields such as solar cells, organic EL devices, semiconductor devices, electromagnetic wave shields, and color filters.
The aluminum foil may be the material with the best barrier property in the barrier materials used on the existing soft plastic package, and the aluminum foil can basically completely isolate gas and moisture under the condition that the thickness of the aluminum foil is enough, so that the aluminum foil layer is mostly arranged on the base material at present, but the aluminum foil has poor processing property in the composite processing process, and is easy to wrinkle and break.
In order to achieve both barrier properties and transparency of a film material, research and development have been conducted to develop a barrier layer film formed of an inorganic oxide film of silicon oxide, aluminum oxide, or the like, which is formed by depositing inorganic oxide particles on a substrate, but since the barrier properties are not satisfactory due to the presence of grain boundaries between the inorganic oxide particles, the thickness of the deposited oxide layer must be increased, but the increase in thickness causes problems such as a decrease in transparency, a poor ductility, and a tendency to crack.
However, in the laminated film formed by forming the inorganic thin film on the surface of the plastic substrate, not only the barrier property but also the bonding strength between the plastic substrate and the inorganic thin film layer need to be considered, and the conventional polymer thin film for depositing the inorganic thin film is physically pretreated by corona, plasma, and the like to increase the surface polarity, thereby increasing the bonding force between the polymer thin film and the inorganic thin film. However, as time goes on, the polarity of the surface of the polymer film gradually decreases or disappears, so that the bonding between the polymer film and the inorganic coating is affected, and under the condition of high temperature and high humidity, the surface tension of the polymer film is suddenly reduced, the inorganic coating layer is easy to fall off, and the practical use requirements cannot be met.
JP 2003-a 71968 discloses a gas barrier plastic film comprising a plastic film (1) and a laminate of a metal oxide layer (2), a resin layer (3) and a metal oxide layer (4) on the surface thereof, wherein the total light transmittance of the film is 85% or more. The oxygen transmission rate and the water vapor transmission rate after 1 minute of immersion in ethyl acetate both decreased by 20% or less, and both the oxygen transmission rate and the water vapor transmission rate were 1 or less.
Further, in order to improve the bonding strength and the barrier property between the coating and the polymer substrate, the researchers also propose to perform the above physical pretreatment on the surface of the polymer substrate, and then perform chemical treatment, and to coat a layer of chemical substance on the surface of the polymer substrate after the physical pretreatment, that is, to arrange a primer layer on the surface to connect the polymer substrate and the coating film, so as to improve the adhesion and the barrier property between the polymer substrate and the coating.
JP 3765190B discloses that at least one surface of a polyester substrate (support) continuously supplied with a crystallinity of less than 80% is subjected to gas discharge plasma treatment at an atmospheric pressure of 500-. JP 3765190B also discloses that heating the substrate to a temperature range of-30% to 0% of the glass transition temperature tg (k) of the polyester before plasma treatment suppresses bleeding of the internal oligomer to the surface, preventing a decrease in the bonding strength with time.
CN201456502U discloses a composite polyester film, which is prepared by coating water-soluble acrylic resin on the surface of the polyester film and compounding the acrylic resin with an aluminum coating, can be cooked at 120 ℃ for 30min without cracking and falling off, and has the defects that the bonding fastness of the aluminum coating and the acrylic resin is not enough, and part of the acrylic resin and the aluminum coating often fall off together in the water cooking process.
CN105949984A discloses a coating liquid, which mainly comprises water-soluble main resin, an adhesion promoter and a nano assistant, wherein the water-soluble main resin is closed isocyanate resin, polyester resin and acrylic resin, the closed isocyanate resin, the polyester resin and the acrylic resin are blended according to the proportion of 1:1:1, and a three-dimensional high-crosslinking density structure is formed by the crosslinking reaction of-NCO, -OH and-COOH groups in the main resin and the addition of high-functionality melamine resin or polyisocyanate resin as a curing agent, so that the binding power of the coating layer is greatly improved. Silane coupling agent is used as adhesion promoter, and by utilizing the hydrolysis characteristic of the silane coupling agent, alkoxy is generated to be combined with the surface of the PET substrate, and active groups at the other end are combined with main resin to be used as a bridging effect, so that the coating is more compact, the adhesive force is further improved, and particularly the adhesive force under the severe environments of humidity resistance, heat resistance and the like is improved. The nano assistant improves the solvent resistance and water resistance of the coating and can greatly improve the adhesive force of the subsequent coating.
CN103144389A discloses a coating liquid, which mainly comprises a water-soluble solvent, a water-soluble polyurethane resin and a cross-linking agent; the content of the water-soluble polyurethane resin is 9-25% of the total weight of the coating liquid; the content of the cross-linking agent is 0.1-0.3% of the total weight of the coating liquid; the friction coefficient of the surface of the polyester film is less than 0.6; the thickness of the coating layer is 0.01-0.05 mu m, and the surface wetting tension is 50-60 mN/m; the coating layer has higher surface tension and water resistance, so that the adhesion between the film and the aluminum layer can be obviously improved by plating aluminum on the formed coating layer, a good aluminum plating enhancement effect is achieved, and the problem that a local plating layer falls off from the polyester film under the high-temperature cooking condition is solved; under the condition of high temperature and high humidity, the film still has good aluminizing composite performance.
Although the coating liquid is widely used in the above patent technologies to enhance the adhesion between the polymer substrate and the inorganic coating film, the adhesion or bonding force is mostly physical force, and the bonding strength is weak, so that the adhesion of the coating is insufficient, and the barrier property of the product will also be insufficient.

The second aspect of the invention relates to a preparation process of a coating liquid used before CPP and PET matrix evaporation.

The third aspect of the invention relates to an evaporation film, which is characterized in that before evaporation, the CPP or PET substrate is coated with the coating liquid, and after the coating process, the evaporation film is obtained by evaporation, and the specific method comprises the following steps:
and C: coating the surface of a polymer substrate with:
(1) pre-treating the polymer substrate:
preferably, the surface of the polymer substrate is pretreated by plasma or corona or a surfactant to change the polarity and the surface activity of the surface of the polymer substrate, so that the adhesion of a primer layer in a later process is facilitated.
The polymeric substrate is preferably a PET or CPP sheet or film article.
(2) Coating and forming a base coat on the surface of a polymer substrate,
and (C) coating the coating liquid in the step (B) on the surface of the polymer base material after the pretreatment by adopting any known technology, such as off-line coating of brushing, rolling, air knife coating, spraying, rotogravure rolling, wire rod drawing and the like, or on-line coating, and performing ultraviolet visible light irradiation after the coating, wherein the coating liquid is cured on the surface of the base material to form a primer layer, and the thickness of the primer layer on the surface of the polymer base material is preferably 1-1000 nm.
Step D: depositing aluminum on the surface of the bottom coating by evaporation
And D, putting the PET film coated with the base coat and obtained in the step C into a vacuum evaporation device, carrying out vacuum evaporation aluminum plating to form a PET aluminum plated film of an aluminum layer with the thickness of 25nm on the base coat, and carrying out characterization evaluation on the water vapor transmission rate and the bonding strength of the obtained evaporation film. The water vapor transmission rate is tested and characterized by GB/T1037-1988, and the plating bonding strength is characterized by GB/T8808-1988.
Advantageous effects
1. By adopting a mercaptan-alkene polymerization system, a mercaptan group is introduced into the primer layer, and can form-S (M-S) or metal O-S (M-O-S) with inorganic metal or nonmetal atoms of the evaporated inorganic thin film layer, wherein M represents the chemical covalent bond of the inorganic metal or nonmetal of the evaporated layer, so that the bonding strength between the inorganic coating and the polymer base material is effectively promoted and improved, the adhesive force of the evaporated inorganic layer is improved, and the barrier property of the evaporated thin film is also improved to a greater extent.
2. It has been shown that (Cramer N B, Bowman C N. kinetic. thermal. ene and thio-acrylate copolymers with real-time Fourier transform incorporated [ J. Polymer. Sci., PartA: Polymer. chem.,2001,39: 3311-. That is, the thiol and the double bond are not copolymerized in a molar ratio of 1:1, but when they are arranged in a molar ratio of 1:1, a part of the acrylate is self-polymerized, and the thiol does not react completely and a part remains in the system. The inventors have found that by setting the molar ratio of thiol/ene in the range of 1.1 to 1.5:1, it is possible to ensure sufficient molecular weight and mechanical strength of the undercoat layer, and to avoid the problem that a large amount of thiol compound does not participate in the reaction and the thiol compound cannot achieve good chemical bonding with the acrylate polymer, and the presence of a free small-molecular thiol compound is also disadvantageous in terms of barrier properties of the evaporated film.
When the ratio is less than the above, self-polymerization of the acrylate monomer is absolutely dominant, resulting in that only a small amount of the thiol compound participates in the reaction, and a large amount of the thiol compound is liberated in the polymer system, so that the bonding of the inorganic plating layer to the undercoat layer is weakened. When the ratio is higher than the above, most of the thiol compounds tend to undergo stepwise polymerization with double bonds, resulting in a decrease in the number of thiol groups present in the final undercoat polymer, resulting in a decrease in the bonding sites between the evaporated inorganic layer and the undercoat layer, and a weakening of the bonding force.
3. The inventors have found that a dithiol compound in which a thiol group is separated by at least 8 carbon atoms can avoid the olfactory stimulation of a developer by a lower thiol and has more excellent bonding strength and barrier properties than a lower dithiol, and have presumed the following two main causes:
(1) the long-chain dithiol compound is adopted to improve the molecular weight of the polymer, the mechanical strength is improved after the molecular weight is improved, the curing volume shrinkage of the base coat can be reduced, and the phenomenon that fine needle holes or depressions are generated on the surface due to the volume shrinkage of the base coat after curing and drying is further reduced, so that the coating is strong in adhesive force.
(2) Due to the existence of the flexible long chain in the long-chain dithiol compound, the mutual contact collision between the polymerized monomers is limited by the movement of the flexible molecular chain, and compared with short-chain dithiol which has higher collision probability and high activity and is easier to realize polymerization crosslinking, a structure with one end connected with acrylate polymer and the other end provided with a free thiol group is easier to form, and the structure is extremely favorable for increasing the bonding strength of a plating layer and a bottom coating, thereby playing a role in more excellent adhesion and barrier property.
4. The addition of silane coupling agent treated nanoparticles to the basecoat composition may, on the one hand, provide reinforcement of the mechanical properties of the basecoat. On the other hand, the nano interface effect can improve the solvent resistance and the water resistance of the coating, and the surface of the coating has certain roughness in a microscopic degree, so that the surface adhesion of the inorganic coating is improved.
The purpose of adopting the silane coupling agent to pretreat the nano particles is mainly to effectively avoid the combination of the added nano particles and free thiol groups in the base coat composition and ensure the sufficient chemical bonding quantity between the thiol groups and the atoms of the coating. Meanwhile, the silane coupling agent can be used as an adhesion promoter, and can play a certain bridging connection role in the system of the invention by utilizing the chemical structure of the silane coupling agent.
5. The base coat formula system can effectively improve the bonding strength of the polymer substrate and the vapor-deposited layer, improve the adhesive force of the vapor-deposited layer and improve the barrier property of the vapor-deposited layer to a greater extent.
