Abstract

The invention relates to an acrylic resin powder composition. The powder composition comprises glycidyl acrylate resin, a curing agent, a leveling agent and a functional nano-filler, and the mass of the functional nano-filler used in the invention is 0.1-1% of the mass of the glycidyl acrylate resin used in the invention. The invention also provides an acrylic resin coating. The coating is a product obtained through carrying out melt extrusion on the acrylic resin powder composition, crushing and sieving the extruded powder composition, and spraying and curing the sieved powder composition. The obtained acrylic resin coating has the characteristics of high hardness, high glossiness, high wear resistance, no discharge of volatile organic compounds, and environmental protection.

Description

technical field [0001] The present invention relates to an acrylic resin powder composition, more specifically the present invention relates to a nano-modified acrylic resin powder composition. Background technique [0002] Due to its non-volatile organic compound (VOC) emission, powder composition coatings are environmentally friendly materials. With the improvement of people's living standards and the enhancement of environmental awareness, powder composition coatings have been developed rapidly. As a natural renewable material, wood is widely used in many aspects such as furniture, woodware, tools and decoration materials. Compared with metal substrates, wood contains more moisture and volatile matter, and it is easy to volatilize when the curing temperature is higher, forming pinholes and other defects on the coating surface, destroying the coating. One of the solutions is to make a textured coating such as sand grain or orange peel, and then cure at low temperature or ...
