Problems solved by technology

[0003]The alloy putty currently on the market generally has the characteristics of high hardness, strong rigidity, etc., and lacks toughness. Once the part coated with alloy ash shrinks greatly, Or when it is impacted by a large external force, it will fall off due to weak toughness and adhesion, and the surface drying of alloy ash is relatively slow

Abstract

The invention belongs to the field of coatings, and in particular relates to superactive alloy polyester putty and a preparation method thereof. The superactive alloy polyester putty comprises a main agent and a curing agent, wherein the main agent comprises synthetic resin, a thickening agent, a brightening agent, an amine promoter and a filler; and the curing agent comprises peroxide and an ester plasticizer. The preparation method comprises the following steps of: (A) preparing a main agent: a1, adding quantitative synthetic resin, brightening agent and amine promoter into a reactor, and stirring; b1, adding the thickening agent into the reactor in the step a, and continuously stirring; c1, adding the filler into the reactor in the step a and stirring; and d1, continuously stirring for 30 to 40 minutes until the materials are fully stirred uniformly; and (B) preparing the curing agent: a2, adding water-containing benzoyl peroxide and dibutyl phthalate into the reactor, and stirring; b2, uniformly stirring, stopping stirring, and separating out water; and c2, repeating the step b2 until water content is not more than 0.5 percent of the total mass. The superactive alloy polyester putty has the characteristics of quick curing, quick drying, capacity of being polished easily, strong adhesion and the like.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a fast-solidifying, fast-drying, easy-to-polish, high-adhesion powerful alloy putty and a preparation method thereof. Background technique [0002] Atomic ash, commonly known as automobile putty, is a fast-growing embedded filling material in the world in the past 20 years. Putty is a kind of unsaturated polyester resin as the main raw material, mixed with cobalt salt initiator, polymerization inhibitor, talcum powder and other additives, and peroxide as curing agent can be used at any time according to actual needs , A convenient and quick new type of embedded filling material. Compared with traditional putty in my country such as tung oil putty, perchlorethylene putty, alkyd putty, etc., putty has the characteristics of fast drying, strong adhesion, heat resistance, no cracking, and short construction period. [0003] The alloy putty currently on the market generally has t...
