Novel acrylic resin bottom face synthetic lacquer

Abstract

The present invention discloses novel acrylic acid resin undersurface synthetic paint for an automobile chassis, which is prepared from the following materials by weight percentage: 5 to 10 percent of 50 percent hydroxy acrylic acid resin (molecular weight is between 25,000 and 30,000), 37 to 57 percent of 50 percent acrylic acid (molecular weight is between 45,000 and 60,000), 1 to 3 percent of carbon black, 3 to 5 percent of talcum powder, 2 to 3 percent of antirust agent, 20 to 25 percent of solvent, 1 to 4 percent of permanent white and 3 to 7 percent of sodium tripolyphosphate. The paint has the advantages of low film forming temperature, high strength and convenient construction.

Description

technical field [0001] The invention belongs to the technical field of chemical paints, in particular to a novel acrylic resin bottom synthetic paint for automobile chassis. Background technique [0002] At present, large parts such as automobile chassis need at least two steps of painting - primer and top coat, which is cumbersome to construct, high in cost and low in strength. Moreover, the currently commonly used acrylic polyurethane paint is a two-component paint, which is expensive and inconvenient for construction. After the two-component paint is prepared, it must be used up within 6 hours, otherwise it will be easily gelled and scrapped, and the paint film needs to be dried at 80 degrees Celsius. Or dry at room temperature for 24-48 hours before handling. Disclosed as Chinese patent CN1102196 " a kind of acrylic finish varnish for luxury car ", its film-forming temperature is high, can only use as top coat. Chinese patent CN1105689 discloses "high-temperature-resis...

Problems solved by technology

Chinese patent CN1105689 discloses "high-temperature-resistance-resistance-retort-retort metal paint", which is a paint made of modified epoxy resin with acrylic resin. Although its strength is relatively high, its film-forming temperature is relatively high and its cost is high, so it is not suitable for Construction of large workpieces like car chassis in small and medium batches

Chinese patent CN1235995 discloses "high-brightness luminescent paint and its manufacturing method", which is made by mixing luminescent powder with acrylic resin, and can only be used as a top coat
