Abstract

The invention discloses multifunctional putty and a preparation method thereof. The multifunctional putty is prepared from unsaturated polyester resin, styrene, talcum powder, barium sulfate, titanium pigment, polymerization inhibitor, accelerator, dispersion wetting agent, thixotropic agent and anti-settling agent in certain proportions, is reacted with benzoyl peroxide (BPO) to be solidified into a film, and is suitable for leveling and repairing metal surfaces of automobiles, trains, machinery and the like. In the multifunctional putty and the preparation method thereof provided by the invention, the prepared multifunctional putty has superior flexibility and adhesive force, can resist temperature as high as 180 DEG C on a steel plate, can be polished within 15 minutes at normal temperature, can be coated as thick as 1cm once, greatly saves the repairing time, improves the efficiency, and simultaneously has good adhesive force on various sheet metal substrates; and in addition, theputty has fine appearance and can be easily coated and scraped, and finish paint can conveniently be coated on the putty.

Description

technical field [0001] The invention relates to the field of paint preparation, in particular to a multifunctional putty and a preparation method thereof. Background technique [0002] With the rapid development of economy and science and technology, the rapid development of manufacturing and repair industries such as automobiles, trains, and machinery has put forward higher requirements for the properties of putty, such as quick drying, easy scraping, and thick coating; on steel plates, Good adhesion on various substrates such as aluminum plate and galvanized plate, etc. [0003] The traditional putty is mainly cured by COPH, which is catalyzed by cobalt compounds. The reaction speed is relatively slow, and the adhesion on the sheet metal is poor due to the large shrinkage during curing; at the same time, the traditional putty cannot be applied thickly at one time It is often required to use thin scraping and multiple constructions, which reduces work efficiency. [0004...
