Wear-resistant, flame-retardant and moisture-absorption-resistant acrylic plate

Abstract

A wear-resistant, flame-retardant and moisture-absorption-resistant acrylic plate is prepared from the following raw materials in parts by weight: 120-160 parts of a PMMA (Polymethyl Methacrylate) acrylic new material, 1-3 parts of an auxiliary agent, 1-3 parts of a flame-retardant component, 1-2 parts of a moisture-absorption-resistant component and 1-3 parts of a wear-resistant and anti-reflection component. The flame-retardant component and the moisture-absorption-resistant component are introduced, so that the fireproof and flame-retardant properties of the acrylic plate are effectively improved, the water absorption rate of the acrylic plate is reduced, and the service life of the acrylic plate is prolonged. Besides, in order to solve the influence of poor wear resistance caused by the two problems, the inventor applies the wear-resistant and anti-reflection component prepared from an ultra-high molecular weight polyethylene material with excellent wear resistance and a micro-porous inorganic nano oxide to the acrylic plate, so that the wear resistance of the acrylic plate is effectively improved. Meanwhile, the micro-porous inorganic nano oxide with excellent specific surface area can improve the diopter of the acrylic plate, improve the transmittance, realize wear resistance, flame retardance and moisture absorption resistance at the same time, and do not influence the light transmittance and impact strength of the acrylic plate.

Description

technical field [0001] The invention belongs to the field of acrylic sheet processing, in particular to a wear-resistant, flame-retardant and moisture-absorbing acrylic sheet. Background technique [0002] Acrylic, also known as plexiglass with special treatment, is a replacement product of plexiglass. It has the reputation of "plastic glass", has strong corrosion resistance, and has strong surface hardness and gloss, so the application of acrylic sheets is also increasing. widely. For example, the light box made of acrylic has the characteristics of good light transmission performance, pure color, rich color, beautiful and smooth, taking into account both day and night effects, long service life, and no influence on use. [0003] However, there are still some deficiencies in the acrylic sheet on the market that limit its application in certain fields, such as 1. The surface wear resistance is average, and scratches during installation and use affect the appearance and ligh...

Problems solved by technology

[0003] However, there are still some shortcomings in the acrylic sheet currently on the market that limit its application in certain fields, such as 1. The surface wear resistance is average, and scratches will affect the appearance and light transmission during installation and use; 2. The resistance The flammability needs to be improved; 3. The water absorption rate is high, and the moisture absorption resistance needs to be improved, etc.

For these problems, companies often pay attention to one thing and lose another in research and development, and cannot do both at the same time. Therefore, how to solve wear resistance, flame retardancy, and moisture absorption resistance without affecting other performances at the same time has become the top priority of research for acrylic sheet manufacturers.
