Description
Technical field
The invention belongs to thickener preparation technical fields, and in particular to a kind of preparation of salt tolerant higher suspension thickener for coating
Method.
Background technique
Modern architecture, construction, house ornamentation all be unable to do without coating, paint.The use of coating is not only to decorate, can also be effectively
Protection basis material, extend building, the service life of equipment etc..Water paint is a kind of low pollution, saves the energy, resource-saving
Coating.With the reinforcement of people's environmental consciousness, water paint is increasingly subject to the attention of people, and Related product is widely studied
And exploitation.Water paint is usually by the dispersion of the emulsion particle of resin, pigment suspension particle, by interparticle mutual
Active force and formed.The viscosity of coating is the characterization of these particle interaction power, and still, these active forces are weaker, thickening
The effect of agent is to increase interparticle interaction, forms network structure.
Thickener is a kind of auxiliary rheological agents.Thickener is added in coating can increase the viscosity of coating, and pigment is made slowly to sink
It forms sediment, to be easy to stir evenly, and then guarantees coating storage stability.The addition of thickener can make coating have centainly thick
Degree and thixotropy brush laborsaving, and drip and sagging when can reduce application in construction, guarantee the appearance and matter of dope layer
Amount.For water paint lower for viscosity, it is very important an analog assistant.
Ideal coating is preferably during storage, or can form solid immediately after homogenous application, thus will not
The separation of pigment or color occurs, but it is actually required to be suitable for applying the liquid of operation.Then pigment is just produced
The problems such as sedimentation separation, drying property, levelability, sagging.Customary thickeners have：Inorganic thickening agent, modified cellulose, polyacrylic acid
The polyurethane thickener of ester and association type.The macromolecules such as cellulose thickener, agent for polyacrylic acid thickening and polyurethane thickener
Thickener at paste property and in terms of performance it is prominent, have a wide range of applications.But they are high in the prevalence of price,
The defects of electrolyte-resistant ability is poor.Inorganic thickening agent also has good thickening capabilities, because of its tool cheap and in use
Have the advantages that thixotropic index is big, sag resistance can good, pH wide adaptation range, be widely used.It should be pointed out that inorganic thickening agent
Thickening capabilities are much smaller than high molecular polymer thickener, therefore are limited use scope.
The thickener of building trade coating is many kinds of at present, but exist mostly suspension, anti-settling property, stability and
The disadvantage of levelability difference, can not accomplish the effect that can thicken in different pH value coating, and it is in anti-layering, resist sagging
The performance of aspect is also poor, so that coating is affected in production, storage, construction, film forming procedure.Therefore, thickener is improved
Anti-settling property seem extremely important.
Therefore, a kind of anti-settling property, levelability and the good thickener for coating of stability are prepared, there is important theory
Meaning and application value.
Summary of the invention
Present invention mainly solves the technical issues of, traditional thickener for current water paint is mainly common organic water
Soluble macromolecular material, they cannot weaken the hydration of emulsion particle in water paint, lead to the salt resistant character of thickener
Difference, the defect of suspension stability difference provide a kind of preparation method of salt tolerant higher suspension thickener for coating.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that：
A kind of preparation method of salt tolerant higher suspension thickener for coating, it is characterised in that specifically preparation step is：
（1）150~160mL epoxychloropropane is added into the three-necked flask with blender and snorkel, three-necked flask is set
In ice-water bath, front three amine gas is led into three-necked flask, starts blender, is stirred with the revolving speed of 200~250r/min, ventilation
It is separated by filtration to obtain white solid product after reaction, is put into and sets in vacuum oven, be dried to obtain cationic etherifying agent；
（2）30~35g hydroxyethyl cellulose, 120~140mL sodium hydroxide solution and 8~10g cation are added into reactor
Etherifying agent is stirred to react, and obtains reaction product, is neutralized reaction product with hydrochloric acid, is obtained suspension, and suspension is placed in high speed
Centrifugal treating in centrifuge removes upper liquid, collects lower sediment thing, sediment is placed in oven and dried, cation is obtained
Hydroxyethyl cellulose；
（3）Mulberry skin machinery is blended, removal filtrate obtains mulberry skin slag, and 80~120g mulberry skin slag is placed in a beaker, and 4~5g is added
Degummase and 200~300mL distilled water, enzymatic hydrolysis, filtering removal filtrate obtain enzymatic hydrolysis fiber, clean enzymatic hydrolysis with sodium hydroxide solution
Fiber obtains mulberry skin and removes glue fiber, goes glue fiber to be put into the four-hole boiling flask with blender and dropping funel mulberry skin obtained
In, 400~450mL ammonium hydroxide is added into four-hole boiling flask, 15~18mL is added dropwise into four-hole boiling flask with dropping funel for heat temperature raising
Carbon disulfide is stirred to react, and obtains reaction product；
（4）30~35min, filtering is mixed in above-mentioned reaction product and 400~500mL Adlerika, removal filtrate obtains
To filter residue, filter residue being washed with dehydrated alcohol, yellow solid is obtained, yellow solid is placed in baking oven, heat temperature raising is dry,
The xanthate of mulberry skin slag is obtained, 100~120mL sodium hydroxide solution is added into the xanthate of mulberry skin slag, obtains fiber
Plain viscose；
（5）40~45mL dimethylallylamine is added into the four-hole boiling flask with condensing unit, heat temperature raising is burnt to four mouthfuls
5~7g monoxone and 60~70mL sodium hydroxide solution are added in bottle, are stirred with magnetic stirring apparatus with the revolving speed of 300~400r/min
It being transferred in distilling flask after mixing reaction, heat temperature raising, distillation obtains the suspension containing white crystal, continuously add 100~
110mL dehydrated alcohol is centrifugally separating to obtain the light yellow mucus in upper layer；
（6）The above-mentioned light yellow mucus of 40~50mL and 80~100mL deionization are added into the three-necked flask equipped with condensing unit
