Abstract
The invention discloses a kind of color inhibition epoxy coating, the raw material of following parts by weight is prepared from: epoxy resin 50 parts～60 parts, 50 parts～60 parts of rosin, butyl acetate 20 parts～25 parts, propylene glycol methyl ether acetate 15 parts～18 parts, polyvinyl alcohol 10 parts～15 parts, 10 parts～12 parts of kieselguhr, sodium dehydroacetate 5 parts～10 parts, dimethylbenzene 5 parts～8 parts, tributyltin chloride 5 parts～10 parts, benzophenone 3 parts～5 parts, Nipagin ester 2 parts～5 parts；Preparation method is: add in reaction vessel by epoxy resin and rosin, and stirring is fully dissolved and added kieselguhr and Nipagin ester, heats up, stirring, reaction；Add butyl acetate, propylene glycol methyl ether acetate, polyvinyl alcohol, sodium dehydroacetate, dimethylbenzene, tributyl chlorination and benzophenone, heat temperature raising, stirring, reaction, cooling, obtain color inhibition epoxy coating。This color inhibition epoxy coating, anti-yellowing property is excellent, after application the several years still pure white as before。
Description
Technical field
The present invention relates to technical field of chemical paint, especially a kind of color inhibition epoxy coating and preparation method thereof。
Background technology
Epoxy coating usually by epoxy resin with microgranule, drop or colloidal form be distributed in solvent the stable dispersion of formation, it is possible to be divided into emulsion, aqueous dispersion or aqueous solution form。Epoxy coating has very strong cohesiveness, and molecular structure is fine and close, and adhesive force is strong, and cure shrinkage is little, has excellent electrical insulating property, stability and resistance to acids and bases。But existing epoxy coating in use easily absorbs the moisture in air, and under ultraviolet effect, the degraded of intensifier ring epoxy resins, cause epoxy coating xanthochromia。
Summary of the invention
It is an object of the invention to provide a kind of color inhibition epoxy coating and preparation method thereof, the problem that this color inhibition epoxy coating can solve paint anti-yellowing property difference。
In order to solve the problems referred to above, the technical solution used in the present invention is:
A kind of preparation method of color inhibition epoxy coating, it is prepared from by the raw material of following parts by weight: epoxy resin 50 parts～60 parts, 50 parts～60 parts of rosin, butyl acetate 20 parts～25 parts, propylene glycol methyl ether acetate 15 parts～18 parts, polyvinyl alcohol 10 parts～15 parts, 10 parts～12 parts of kieselguhr, sodium dehydroacetate 5 parts～10 parts, dimethylbenzene 5 parts～8 parts, tributyltin chloride 5 parts～10 parts, benzophenone 3 parts～5 parts, Nipagin ester 2 parts～5 parts；
Preparation method comprises the following steps:
A, epoxy resin and rosin are added in reaction vessel, magnetic agitation, fully dissolve；
B, in described reaction vessel, add kieselguhr and Nipagin ester, be warming up to 80 DEG C～90 DEG C, magnetic agitation, react 30 minutes～60 minutes；
C, in described reaction vessel, it is slowly added to butyl acetate, propylene glycol methyl ether acetate, polyvinyl alcohol successively, sodium dehydroacetate, dimethylbenzene, tributyltin chloride and benzophenone, be heated to 110 DEG C～120 DEG C, magnetic agitation, react 2 hours～3 hours, cooling, filter, remove filtering residue, obtain color inhibition epoxy coating。
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, this color inhibition epoxy coating with the addition of the uvioresistant additive such as benzophenone and tributyltin chloride, has delayed the xanthochromia time of epoxy coating, can brushing interior wall, timber, plastic etc., after application 5 years even above still pure white as before。
2, this color inhibition epoxy coating smooth coating, hard, bright in color, weatherability is strong, scratch resistance, and stain resistance is strong, easy to clean, and solid content is high, and VOC content is relatively low, is a kind of function admirable, the paint of environmental protection。
