Abstract
The present invention discloses a high adhesion thermoplastic acrylic acid resin, which is prepared from the following raw materials, by weight, 20-30 parts of methyl methacrylate, 3-12 parts of butyl acrylate, 1-5 parts of 2-hydroxyethyl acrylate, 5-15 parts of vinyl chloroacetate, 0.1-0.5 part of benzoyl peroxide, 8-20 parts of chlorinated polypropylene, and 40-65 parts of an organic solvent. According to the high adhesion thermoplastic acrylic acid resin, a large amount of experiments are performed to preferably select raw material composition and the optimal ratio of various raw materials, wherein the ratio of various components is scientific and rational; and performance test results show that the high adhesion thermoplastic acrylic acid resin has characteristics of fast drying, good gloss and color retention, good recoatability, excellent water resistance, excellent chemical resistance, easy construction and high adhesion, wherein strong adhesion is especially provided for a base material after the high adhesion thermoplastic acrylic acid resin is provided for PP and aluminum powder paint preparation post-illumination two-component PU, and the resin can be widely used in vehicles, electrical appliances, machinery, construction and other fields.
Description
Technical field
The present invention relates to a kind of resin, be specifically related to the thermoplastic acrylic resin of the high adhesive force that a kind of acrylic plastering uses.
Background technology
Acrylic resin is the resin of being made up of esters of acrylic acid and methyl acrylic ester and other olefinic type monomers copolymerization, by selecting different resin structures, different formula, production technique and solvent composition, the acrylic resin that can synthesize dissimilar, different performance and different application occasion, acrylic resin can be divided into again thermoplastic acrylic resin and thermosetting acrylic resin according to the difference of structure and membrane formation mechanism.Thermoplastic acrylic resin does not occur further crosslinked in film process, and therefore its relative molecular weight is larger, has good guarantor's light tint retention, water-fast chemical resistant properties, fast drying, easy construction, and recoat and doing over again is easy to construct.But the thermoplastic acrylic resin of prior art is general to PP sticking power, poor to substrate adhesion according to two-pack PU after aluminium powder paint processed, limit to a certain extent its application.Therefore necessaryly on the basis of prior art, research and develop the thermoplastic acrylic resin that a kind of sticking power is high.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is to overcome thermoplastic acrylic resin in prior art to shine two-pack PU to the poor deficiency that waits of substrate adhesion after aluminium powder paint processed, provide a kind of component proportioning scientific and reasonable, fast drying, protect light tint retention good, recoatability is good, water-fast chemical resistant properties excellence, is easy to construction, has the thermoplastic acrylic resin of high adhesive force.
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
A kind of thermoplastic acrylic resin of high adhesive force, it is made up of the raw material of following parts by weight: thermoplastic acrylic resin is as preferred version, the thermoplastic acrylic resin of above-described high adhesive force, it is made up of the raw material of following parts by weight: 20 ~ 25 parts of methyl methacrylates, 3 ~ 5 parts of butyl acrylates, 1 ~ 2 part of Hydroxyethyl acrylate, 5 ~ 10 parts of vinyl chloroacetates, 0.1 ~ 0.5 part of benzoyl peroxide, 8 ~ 15 parts of Chlorinated Polypropylene IIIs, 60 ~ 65 parts of organic solvents.
As preferred version, the thermoplastic acrylic resin of above-described high adhesive force, it is made up of the raw material of following parts by weight: 20 parts of methyl methacrylates, 3 ~ 4 parts of butyl acrylates, 1 part of Hydroxyethyl acrylate, 5 ~ 8 parts of vinyl chloroacetates, 0.1 ~ 0.3 part of benzoyl peroxide, 8 ~ 10 parts of Chlorinated Polypropylene IIIs, 60 parts of organic solvents.
As preferred version, the thermoplastic acrylic resin of above-described high adhesive force, described organic solvent is toluene.
Beneficial effect: the thermoplastic acrylic resin of high adhesive force provided by the invention compared to the prior art tool has the following advantages:
The thermoplastic acrylic resin of high adhesive force provided by the invention, for the deficiencies in the prior art, optimizes the best proportioning of each raw material composition and each raw material by great many of experiments, each component proportion is scientific and reasonable; Performance test results shows, thermoplastic acrylic resin provided by the invention, rate of drying is fast, protect light tint retention good, recoatability is good, water-fast chemical resistant properties excellence, be easy to construction, and there is high adhesive force, especially, to strong to substrate adhesion according to two-pack PU after PP and aluminium powder paint processed, can be widely used in the fields such as automobile, electrical equipment, machinery, building.
