Accordingly, the present invention also provides a kind of spun glass membrane-forming agent of technique scheme preparation.
Accordingly, the present invention also provides a kind of treating compound, comprises the described spun glass membrane-forming agent of technique scheme.
The present invention provides a kind of preparation method of spun glass membrane-forming agent, may further comprise the steps: ppe and organic solvent are mixed, be warming up to 100~105 ℃, obtain resin solution; In said resin solution, add emulsifying agent, under the high speed shear effect, add entry, continue high speed shear, utilize the phase reversion method to prepare the spun glass membrane-forming agent.Compared with prior art; The present invention is that feedstock production has obtained the spun glass membrane-forming agent first with ppe; Because advantages such as ppe has that rigidity is big, thermotolerance is high, difficult combustion, intensity is higher and electrical property is good, thereby guaranteed to use the spun glass of this spun glass membrane-forming agent to have the good mechanical performance.And; Owing to the membrane-forming agent that with ppe is feedstock production is structurally approaching with back expectation enhanced polyphenylene oxide resin, thereby guaranteed to use the spun glass of this spun glass membrane-forming agent and back to expect between the enhanced polyphenylene oxide resin good interface bonding force is arranged.
Embodiment
Carry out clear, intactly description in the face of the technical scheme in the embodiment of the invention down, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The invention discloses a kind of preparation method of spun glass membrane-forming agent, it is characterized in that, may further comprise the steps: step a) is mixed ppe and organic solvent, is warming up to 100~105 ℃, obtains resin solution; Step b) adds emulsifying agent in said resin solution, under the high speed shear effect, add entry, continues high speed shear, obtains the spun glass membrane-forming agent.
The present invention is with the raw material of ppe as preparation spun glass membrane-forming agent, and ppe (PPO) not only has good physical and mechanical property, electric insulating quality and thermotolerance, and the creep resistant under its high temperature is better.Ppe is the high-strength engineering plastic that grows up the sixties in 20th century, and chemical name is for gathering 2,6-dimethyl--1; The 4-phenylate; Be called for short PPO (Polyphenylene Oxide) or PPE (Polypheylene ether), be called polyphenylene oxide or polyhenylene ether again, structural formula is following:
Figure BDA0000144771920000031
In addition; The present invention does not have special restriction for the organic solvent that adopts; The organic solvent that can adopt the field personnel to know, the preferred employing and the good organic solvent of ppe consistency is like toluene, YLENE or propylene glycol monomethyl ether; More preferably adopt and the good environment-friendly type organic solvent of ppe consistency, most preferably be propylene glycol monomethyl ether (2-MP).Propylene glycol monomethyl ether is a kind of low toxicity advanced industrial solvent, and existing ehter bond in the molecule has carbonyl again, and carbonyl has formed the structure of ester again, contains alkyl simultaneously again.Therefore, propylene glycol monomethyl ether is existing nonpolar part in a part, and the polarity part is arranged again, and this two-part functional group both mutual restriction repels, and plays its inherent effect again separately, thereby apolar substance and polar material are all had very strong dissolving power.
Consider that from the properties of ppe the present invention is warming up to 100~105 ℃ with after ppe and the organic solvent mixing, is preferably 102~105 ℃, more preferably 105 ℃; Soaking time is preferably 3~5h, more preferably 5h.With ppe and solvent, ppe dissolves under this temperature, and forming heavy-gravity liquid is resin solution, has guaranteed that the phase reversion legal system is equipped with carrying out smoothly of spun glass membrane-forming agent.Simultaneously, the mass ratio of ppe and organic solvent is the important factor that influences the viscosity of resin solution, and then influences the final character of membrane-forming agent.The ppe that the present invention adopts and the mass ratio of organic solvent are preferably 1: (0.1~0.5), more preferably 1: (0.2~0.3), more preferably 1: 0.2.
After preparing resin solution, prepare the step of spun glass membrane-forming agent, said step b) is specially: step b1) in said resin solution, add emulsifying agent, obtain mixing solutions; Step b2) in said mixing solutions, adds entry under the high speed shear effect, continuing high speed shear, preparing the spun glass membrane-forming agent.
In preparation spun glass membrane-forming agent process, in the high speed shear process, realized phase reversion.The phase reversion method promptly becomes oil-in-water state with polymkeric substance from the water-in-oil state-transition through phase reversion; Be a kind of effective ways that prepare the macromolecule resin emulsion, can macromolecule resin be made corresponding emulsion by means of the effect that adds emulsifying agent and through physics emulsive method.For the present invention, because the fusing point of PPO resin is higher, even be heated to softening temperature; Resin also can be met cold moment and is transformed into arborescens, can't form flowability liquid preferably, therefore; The present invention adds emulsifying agent in said resin solution, adopt the emulsification of phase reversion method to the PPO resin.As preferably, the present invention adopts preferably that cloud point is higher, emulsifying capacity emulsifying agent, more preferably environment-friendly type Fatty Alcohol(C12-C14 and C12-C18) ethers emulsifying agent preferably.
According to the present invention, the said emulsifying agent that in resin solution, adds preferably carries out under 90~100 ℃, and more preferably 95~100 ℃, more preferably 95 ℃.Therefore, after step a) prepares resin solution, preferably lower the temperature, in said resin solution, add emulsifying agent after preferably reducing to 95 ℃.In addition, in the step b), the temperature of said water is preferably 90~100 ℃, and more preferably 95~100 ℃, more preferably 95 ℃.
In the prior art, polyurethanes membrane-forming agent and epoxy resin membrane-forming agent are two types of important membrane-forming agents, and it is-NHCOO-that epoxy resin has following structural formula that the primary structure of urethane contains ammonia ester bond:
Figure BDA0000144771920000051
Though urethane and epoxy resin all have stronger ehter bond of polarity and amine ester bond; The effect of certain bonding interface is arranged; But, when the spun glass that uses membrane-forming agent is used for the polyphenylene ether resin matrix and strengthens, according to the principle of similar compatibility; The glass surface IT when strengthening the PPO matrix resin of spun glass membrane-forming agent that is coated with the present invention preparation is littler, and binding ability is better.Experimental result shows; The spun glass polyphenylene ether resin matrix that utilization is coated with the spun glass membrane-forming agent of the present invention's preparation strengthens; The interface bonding of polyphenylene oxide resin matrix strengthens; Cushioned the impact of extraneous power to material, mechanical properties such as the stretching of material, bending, impact are greatly improved.
In sum; The present invention is that feedstock production has obtained the spun glass membrane-forming agent first with ppe; Because advantages such as ppe has that rigidity is big, thermotolerance is high, difficult combustion, intensity is higher and electrical property is good, thereby guaranteed to use the spun glass of this spun glass membrane-forming agent to have the good mechanical performance.And; Owing to the membrane-forming agent that with ppe is feedstock production is structurally approaching with back expectation enhanced polyphenylene oxide resin, thereby guaranteed to use the spun glass of this spun glass membrane-forming agent and back to expect between the enhanced polyphenylene oxide resin good interface bonding force is arranged.
