Description
Technical field
But the present invention relates to a kind of high abrasion self-healing rubber feel plastic coating priming paint and production and using method, belong to the chemistry painting industry technical field.
Background technology
Handfeel paint claims rubber paint, elastomeric paint again, is sprayed at body surface, is mute light or half mute light state, and feel is quite fine and smooth, level and smooth, outward appearance grace, serious, scratch-proofness, weather resisteant, high abrasion resistance.
Priming paint is the first layer of paint system, be used to improve finish paint sticking power, increase finish paint fullness ratio, alkali-resistivity is provided, anti-corrosion function etc. is provided, can guarantee the even absorption of finish paint simultaneously, make paint system performance best effect.Finish paint is different with the function of priming paint, and finish paint lays particular emphasis on final decoration and apparent effect more, and priming paint then lays particular emphasis on and improves sticking power, anti-corrosion function, alkali-resistivity etc.
Thermoplastic resin is meant the organic high molecular compound with linearity or ramiform structure, and these resinoid characteristics are to meet thermal softening or fusion and be in the plasticity-state, become hard after the cooling again, and this process can be carried out repeatedly.
Acrylic resin is the resin of being made by esters of acrylic acid and methyl acrylic ester and other olefinic type monomers copolymerization, by selecting different resin structures, different prescription, production technique and solvent composition for use, can synthesize the acrylic resin of dissimilar, different performance and different application occasion, acrylic resin can be divided into thermoplastic acrylic resin and thermosetting acrylic resin again according to the difference of structure and membrane formation mechanism.Thermoplastic acrylic resin can fusion, dissolve in appropriate solvent, by macromolecular gathering film forming after the solvent evaporates, does not have crosslinking reaction to take place by the coating of its configuration during film forming, belongs to non-response type coating.Such coating has the principal advantages of acrylic coating, and good weatherability is protected light, tint retention is good, water-fast, acidproof, alkaline-resisting good.Commercially available thermoplastic acrylic resin is divided into various series, and is common just like models such as A type, Type Bs, all can buy through commercially available.
The solvent based coating wetting and dispersing auxiliary of high molecular, it prevents the pigment reflocculation by sterically hindered stabilization, therefore tinting strength and the form and aspect of pigment in coating and pigment slurry is settled out.The high molecular block copolymerization liquid solution of band pigment affinity groups is a chemistry painting industry field component commonly used, all can buy by commercially available.
3c product plastic casing carries out elastic handfeel coating and is popular in plastic prod at present and adds industry and commerce, but the problem that makes numerous paint supplier and plastics outward appearance add industrial and commercial headache at present often is: good rubber sense of touch and good coating property are can't eat one's cake and have it.Many manufacturers often are the supporting ratios that improves solidifying agent for the method for the anti-RCA performance that strengthens coating, though this can make the wear resisting property of elastic handfeel coating be improved, but are prerequisite to lose good caoutchouc elasticity sense of touch.
