Abstract

The invention relates to colored putty and a preparation method thereof, belonging to the field of putty and consisting of a main agent and a curing agent, wherein the main agent comprises unsaturated polyester resin, styrene, an accelerant, a polymerization inhibitor, a cobalt salt initiator, talcum powder, titanium pigment, methacrylic acid, phenylformic acid, toluidine, color concentrate and nitrile rubber; and the curing agent comprises colorless permanent curing agent and peroxide; and the colored putty is prepared by stirring the main agent with the curing agent in mass ratio of 100:2. The colored putty is suitable for coating the surface of an automobile body and has the advantages that primer is avoided, coating work procedures are reduced, the repair time is saved and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of putty, and in particular relates to a colored putty and a preparation method thereof. The colored putty is prepared by adding color essence into the putty, which is used for automobile repair. Background technique [0002] Atomic ash is commonly known as putty, also known as unsaturated polyester resin putty. It is a fast-growing filling repair material in the past 20 years. Its appearance has made the once backward automobile sheet metal repair industry achieve a leap forward across the ages. In the process of automobile manufacturing, due to the defects of molds, welding precision and artificial bumps during the transfer process, there will be some defects such as pits, pockets, waves and other defects on the sheet metal parts. In order to increase the flatness of the whole vehicle after painting, putty is required To make up for the defects on these sheet metal parts; in addition, for the accident car,...
