Problems solved by technology

[0003] The surface of the melamine board is flat, very smooth, and is not easy to adhere. In the prior art, the melamine board coating can meet people's needs to a certain extent, but it still has the following disadvantages: 1. Many melamine board coatings have poor adhesion and are not suitable for melamine. When the board is painted, it needs to be polished so that it can be attached to the surface of the melamine board, which is laborious and laborious, and increases the cost, and cannot meet people's requirements for high quality
2. Most of the melamine board coatings currently on the market are oil-based coatings. The film-forming substances are mainly from petrochemical products, and the solvents are mostly organic solvents, which often contain toxic substances such as formaldehyde, free TDI and xylene. These substances are in melamine Continuous volatilization during the production and use of board coatings will not only cause environmental pollution, but also damage human health
3. Oily melamine board coating, after curing, has poor resistance and dull appearance

Abstract

The invention relates to the technical field of paint, in particular to acrylic resin for a melamine board, and aims at solving the technical problems to provide waterborne melamine board paint with the advantages of superstrong adhesive force, high solid content, low viscosity, pollution resistance, ageing resistance, high drying speed, good fullness, safety and environment-friendly effect. The acrylic resin has the technical scheme that the acrylic resin is prepared from the following raw materials in parts by weight: 10 to 20 parts of methacrylic acid, 15 to 25 parts of ethyl methacrylate,20 to 30 parts of n-butyl methacrylate, 15 to 25 parts of isobornyl methacrylate, 1 to 5 parts of N-methylolacrylamide, 15 to 25 parts of aliphatic polyacrylate, 0.5 to 2 parts of initiating agents, 3.75 to 28 parts of silane coupling agents and 7.5 to 15 parts of prepolymers.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an acrylic resin for melamine boards. Background technique [0002] Paint is an indispensable decorative material in modern life. The application of paint gives people a sense of beauty, touch, and even colorful color vision, and gives the painted object beauty, decoration and protection. With the enhancement of human awareness of environmental protection, various countries have successively formulated environmental protection regulations on the emission of volatile organic compounds (VOC). In the field of paint coating, the development and application of safe and low-VOC water-based environmentally friendly coatings is imperative. [0003] The surface of the melamine board is flat, very smooth, and difficult to adhere. In the prior art, the melamine board coating can meet people's needs to a certain extent, but it still has the following disadvantages: 1. Many melamine board co...
