Abstract

The invention relates to a high-performance automobile acrylic modified varnish and a preparation method of the automobile acrylic modified varnish. The high-performance automobile acrylic modified varnish is prepared from the following raw materials in parts by weight: 60-80 parts of resin, 5-10 parts of auxiliary agent and 10-30 parts of solvent; the preparation method comprises the steps of adding 80-90wt% of resin and 60-70wt% of solvent into a reaction vessel, stirring at a high speed for 30-60min, then adding the rest of resin and the formula amount of auxiliary agent into the mixture, stirring for 10-30min, measuring the solid content of the mixture, and adjusting the solid content to be qualified by using the rest solvent. Compared with the prior art, the high-performance automobile acrylic modified varnish has better mechanical property and has the advantages of ultraviolet resistance, ageing resistance, electrostatic shielding effect, etc.

Description

technical field [0001] The invention relates to an automobile paint and a preparation method thereof, in particular to a high-performance automobile acrylic modified varnish and a preparation method thereof. Background technique [0002] Automobile coating is a kind of coating with high technology content and high added value. It represents the level of a country's coating industry. With the development of the automobile industry, the domestic demand for automotive coatings is increasing. What follows is, Customers have stricter requirements on the appearance of cars. Automobile varnish is an intuitive evaluation of automobile quality. It not only determines the appearance of automobiles, but also directly affects the market competitiveness of automobiles. Therefore, in addition to high decorativeness, automotive topcoats also require excellent durability, including resistance to ultraviolet rays, moisture, chemicals and acid rain, and anti-scratch performance. [0003] Th...
