Acrylic acid modified epoxy resin paint and use method thereof

Abstract

The invention discloses acrylic acid modified epoxy resin paint, which is prepared from 50 to 80 parts of acrylic acid, 20 to 35 parts of vinyl acetate, 1 to 2 parts of ammonium persulfate, 3 to 6 parts of curing agents, 60 to 90 parts of epoxy resin and 10 to 15 parts of butyl amine. The invention also discloses a use method of the acrylic acid modified epoxy resin paint. The method comprises thesteps of low-temperature preparation of ingredient A and B particles, primary hot roller rolling at 50 to 60 DEG C and secondary hot roller rolling at 150 to 160 DEG C. The acrylic acid modified epoxy resin paint has the beneficial effects that all ingredients of the acrylic acid modified epoxy resin paint do not contain organic solvents; no VOC harmful gas is volatilized in the construction anduse process; waste water, waste gas and waste slag cannot be generated; the safe, environment-friendly and nontoxic effects are achieved; in the use process, the formation is controlled by using different polymerization degrees of all ingredients; after coating, heating is performed for secondary melting; secondary reaction is performed at high temperature into a coated surface; the levelling property of the two-ingredient particle paint is good; the adhesive force is strong; the impact resistance is realized; the shrinking rate is small; the coating thickness is controlled; the production process is simple; the use is convenient; the cost is low.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an acrylic modified epoxy resin coating and its application method. Background technique [0002] Powder coating is a new type of solvent-free 100% solid powder coating, which has the characteristics of non-polluting, recyclable, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. There are many polymer resins that can be used as powder coatings. According to the properties of film-forming materials, they can be divided into two categories: thermoplastic and thermosetting. Thermoplastic powder coatings include polymers composed of some simple monomers, such as PE, PP, PVC, polyester and cellulose, etc., thermosetting powder coatings include polyurethanes, polyester resins and epoxy resins. [0003] Powder coatings are prepared by mixing specific resin fillers, curing agents and other additives in a certain proportion, and then through h...
