Problems solved by technology

[0003] Water-based acrylic resin coatings with acrylic 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, ordinary water-based acrylic resins have high viscosity, poor leveling, and high temperature Disadvantages such as poor fluidity and high low temperature brittleness

Embodiment Construction

[0033] The content of the present invention is further described below by way of examples.

[0034] 1. Preparation of fluorosilicone modified acrylate emulsion

[0035] (1) After mixing absolute ethanol with a mass ratio of 65:1 and hydrophilic silica airgel micropowder and ultrasonically dispersing for 2 hours, the specific surface area of ​​silica airgel is 700m 2 / g, the particle size of silica airgel powder is 25nm.

[0036] The temperature of the dispersed silica airgel and ethanol mixture was raised to 70°C with mechanical stirring, and KH570 was added to react for 40 minutes, wherein the amount of KH570 added was 1.5 times the mass of silica airgel powder.

[0037] (2) The product in (1), perfluoroalkyl ethyl acrylate, methyl methacrylate, butyl acrylate, methacryloyloxyethyltrimethylammonium chloride, and hydroxyethyl acrylate were measured by mass Ratio 1:15.6:14.8:8.5:10:0.5 into the reactor, then add 0.8% azobisisobutyronitrile of the above mixture mass, use 0.05%...

Abstract

The invention discloses environment-friendly furniture coating. The environment-friendly furniture coating comprises the following components: water, fluoro-silicone modified acrylate emulsion, pure acrylic emulsion, a film forming auxiliary, a dispersing agent, a thickening agent, a preservative bactericide, a defoaming agent and a pH value regulator, wherein the fluoro-silicone modified acrylate emulsion is self made by adopting an emulsifier-free polymerization process. The environment-friendly furniture coating has good adhesion on the surface of a base material of wood and aluminum alloy furniture, does not volatilize VOC and is environment-friendly in production and using processes; meanwhile, the fluoro-silicone modified acrylate emulsion adopts a soap-free emulsion polymerization process, no emulsifier is added, and cleanliness of emulsion particles is further improved.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based environmental protection coating suitable for furniture. 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. The traditional furniture paint in the prior art is mainly for the purpose of application, and its performance is the most important index to measure...
