Problems solved by technology

[0004] In addition, the existing coatings need to use a variety of raw materials in the preparation process. In the past, various raw materials were poured into a large tank for stirring, and the components were gradually mixed with the stirring, but this method of stirring and mixing There are still uneven mixing and low efficiency, so that there is color difference after the product leaves the factory

Abstract

The invention belongs to the field of coatings, in particular to a coating containing a quick drying agent and a preparation method thereof. The coating includes a paint component and a curing agent component, and the mass ratio is 2-3:1; the composition of the paint component is calculated by mass fraction: polysulfide modified epoxy resin 40-50%, acrylic resin 5-10%, Polydimethylsiloxane 15-20%, additives 1-5%, pigments and fillers 10-15%, solvent 10-20%, tea stem powder 5-10%, coupling agent 2-5%; curing agent The composition of components is calculated by mass fraction: curing agent 60-70%, n-butyl acetate 20-30%, fast drying agent 10-15%; the composition of fast drying agent is calculated by weight fraction: dehydrating agent 10-15% , Drier 15-25%, n-butyl acetate 60-70%. The invention can react with volatile organic gas to a certain extent by adding tea stem powder, and reduce the VOCs released by the coating. At the same time, it is designed with a fast drying agent, which can make the coating dry quickly. It is a solvent-based relatively environmentally friendly and fast-drying coating. .

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a coating containing a quick drying agent and a preparation method thereof. Background technique [0002] According to the "2013-2017 China's Automobile Coatings Industry Production and Sales Demand and Investment Forecast Analysis Report", at present, my country's auto sales have continuously exceeded 18 million, and the rapid growth of auto sales has strongly stimulated the continued development of the auto coating business. The automotive coatings industry presents enormous business opportunities. However, when the car is traditionally painted, the drying condition of the original paint is generally baked at 70°C for 50 minutes, which consumes a lot of energy, takes a long time to bake, and wastes manpower and material resources. The growing demand has greatly restricted the rapid development of the domestic automobile industry. Moreover, automobile paint is a viscous oily pigment, wh...
