Fast drying paint

Abstract

The invention relates to a fast drying paint with the components of, by weight, 40-60% of alkyd resin, 20-30% of cellulose resin, 3-4% of auxiliary agents, and balance of a solvent. The solvent is a mixture of toluene, methanol and butyl ester with a weight ratio of 3:3:4. According to the cellulose resin, resin solution with a concentration of 40-60% is dissolved with cellulose with a 100% solid content and with a solvent, such that a usage concentration is reached. The auxiliary agents is on or more selected from a siccative, a toughening agent, a defoaming agent, a leveling agent, a light stabilizer, and the like. The baking varnish paint used in metal surface coating has the advantages of convenient construction and fast surface drying. The paint can form a basic film 5min after coating. A one-time yield can reach 98%. A rework piece does not need bake-drying before repairing, and can be directly reworked and coated for a second time. Therefore, utilization cost is reduced, repairing cost is reduced, and yield is improved. When the paint is used for recoating a secondary thermosetting resin paint, no chemical reaction is caused, and product quality is not influenced.

Description

technical field [0001] The invention relates to a quick-drying paint, in particular to an alkyd resin low-temperature drying paint, which is suitable for raw material accessories such as PP, PV, PS, and front and rear bumpers of various automobiles. Background technique [0002] The original paint used for automobile bumpers comes from two-component thermoplastic paints, and the process is complicated. The manufactured workpieces need to be dried once before they can be painted for the second time. On the one hand, the yield of rework and polishing is relatively low. Generally, the yield of one pass is about 60%. Therefore, the cost of rework is high, which affects production capacity and increases energy consumption. For a long time, it has been impossible to change the current status of the existing production and processing coatings, so that the unit output and benefits cannot be achieved. ensure.
