Example Embodiment
[0031] Example 1
[0032] Antibacterial acrylic board raw materials: 100 kg of methyl methacrylate, 0.8 kg of dicumyl peroxide, 20 kg of fly ash, 0.4 kg of 3-(2,3-epoxypropoxy) propyltrimethoxysilane, two 0.2 kg of methyl silicone oil, 3 kg of inorganic antibacterial agent, 0.69 kg of ultraviolet absorber.
[0033] The inorganic antibacterial agent is obtained by stirring and mixing zinc stannate, zinc titanate and zinc molybdate at a mass ratio of 1:1:1.
[0034] The ultraviolet absorber is composed of 1-(methyl)-8-(1,2,2,6,6-pentamethyl-4-piperidine) sebacate, bis(1-octyloxy-2) ,2,6,6-Tetramethyl-4-piperidinyl) sebacate, 3,5-di-tert-butyl-4-hydroxybenzoic acid-2,4-di-tert-butylphenyl ester by mass ratio Stir and mix evenly at 1:1:1.
[0035] The preparation method of antibacterial acrylic sheet includes the following steps:
[0036] (1) Mix methyl methacrylate and dicumyl peroxide uniformly, then heat and polymerize in a water bath at 82°C for 28 minutes, and finally cool to room t...

Abstract
The invention discloses an antibacterial acrylic board and a preparation method thereof. The antibacterial acrylic board is prepared from the following raw materials by weight: 95 to 105 parts of methyl methacrylate, 0.1 to 1 part of dicumyl peroxide, 15-25 parts of fly ash, 0.1-0.5 part of 3-(2,3-epoxypropoxy)propyltrimethoxysilane, 0.1-0.5 part of dimethicone, 1-5 parts of an inorganic antibacterial agent and 0.5-1.5 parts of an UV absorber. The antibacterial acrylic board in the invention is simple in the composition of raw materials and good in comprehensive mechanical properties; the board has antibacterial, anti-mildew and illumination aging-resistant functions and other functions and has antibacterial effect of more than 99%; and the board is smoother and brighter compared with common products, has high efficiency and heat resistance, and can maintain good antibacterial properties after usage for a long time.
Description
technical field [0001] The invention relates to the field of composite plates, in particular to an antibacterial acrylic plate and a preparation method thereof. Background technique [0002] With the gradual improvement of people's living standards, various decorative materials appear in major public places, luxury hotels, shopping malls and families. As a new type of organic decorative material, acrylic sheet gradually plays an important role in people's daily life. In the market, general acrylic sheets are rich in color and variety, but their strength and toughness are not high, and they are expensive. They are used as cabinet panels and other products. Most of the high-end acrylic sheets are filled with marble, which has high strength, but poor toughness and bulkiness. At the same time, these acrylic sheets are flammable products. [0003] Acrylic, also known as PMMA or acrylic, comes from English acrylic (acrylic plastic). The chemical name is polymethyl methacrylate,...
