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 and particularly relates to a coating containing a quick drying agent and a preparation method thereof. The coating comprises a paint component and a curing agent component in a mass ratio of (2-3) to 1, wherein the paint component comprises the following components by mass percent: 40-50% of polysulfide modified epoxy resin, 5-10% of acrylic resin, 15-20% of polydimethylsiloxane, 1-5% of additive, 10-15% of pigment and filler, 10-20% of a solvent, 5-10% of tea stem powder and 2-5% of coupling agent; the curing agent component comprises the following components by mass percent: 60-70% of a curing agent, 20-30% of n-butyl acetate and 10-15% of quick drying agent; and the quick drying agent comprises the following components by weight percent: 10-15% of a dehydrating agent, 15-25% of drier and 60-70% of n-butyl acetate. According to the coating, the tea stem powder is added to be reacted with volatile organic gas and thus the VOCs (Volatile Organic Chemicals) released by the coating is reduced and meanwhile the quick drying agent is added so as to quickly dry the coating and coating is a solvent-type relatively environment-friendly, quick drying material.

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. It is increasingly unable to meet the increasing market demand for automotive paint. The growing demand has greatly restricted the rapid development of the do...
