Problems solved by technology

Water-based coatings with alkyd resins as film-formers have become the most commonly used water-based coating systems due to their excellent weather resistance, oil resistance and high hardness. However, water-based alkyd resins have the disadvantage of poor dispersion, and there are uneven surfaces on the painted surface. , the surface is not beautiful, and it needs to be solved urgently

Abstract

The invention discloses a preparation method of an alkyd resin coating capable of forming flat surfaces. The method comprises the steps as follows: polyvinyl alcohol and bamboo charcoal powder are stirred, a silane coupling agent is added, grinding is performed, agarose is added, ultrasonic treatment is performed, and a first material is obtained; fumed silica, wollastonite powder, vermiculite powder, nano talcum powder, acetic ether, the first material and water are mixed, ultrasonic treatment is performed, and a second material is obtained; phenolic aldehyde modified alkyd resin, acrylic acid modified alkyd resin, diethylene glycol methyl ether acetate, ethylene glycol, waterborne polyurethane resin, polyamide polyamine epoxy chloropropane resin and oxidized polyethylene wax are uniformly stirred, the second material, polyoxypropylene glycerol ether, hydroxyl silicone oil, sodium lauryl sulfate, a wetting agent and a preservative are added, the mixture is stirred continuously, and the alkyd resin coating capable of forming the flat surfaces is obtained. The method is simple, and the obtained coating has good base material adhesion and film compactness, is not prone to peeling offand has good heat and damp resistance and temperature change resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a method for preparing alkyd resin coatings with smooth surfaces. Background technique [0002] In the process of modern home decoration, it is inevitable to come into contact with a large amount of paint, especially in order to make the furniture beautiful, the manufacturer will coat a large amount of paint on the surface of the furniture. With the gradual improvement of living standards, people's awareness of environmental protection and health has become stronger and stronger, and more requirements have been placed on the coatings used on the surface of furniture. In addition to stable quality and beautiful coating, there are also such as no peculiar smell, no poison Volatilization of substances, environmental protection and other requirements. [0003] A large amount of organic volatiles are used in traditional furniture coatings, which has caused great harm to the environm...
