Problems solved by technology

It is usually used in lampshades, billboards, etc. Such products usually require heat resistance, oxidation resistance, corrosion resistance, and certain mechanical strength and quality, but the existing polymethyl methacrylate cannot meet the above requirements , and PMMA plastics have great disadvantages, such as low surface hardness, easy to rub hair, low impact resistance, poor molding fluidity and other shortcomings, which seriously restrict the wide use of PMMA plastics.

Embodiment 1

[0027] Antibacterial acrylic sheet material (parts by weight): 100 parts of methyl methacrylate, 0.4 part of dicumyl peroxide, 20 parts of aluminum hydroxide, 0.3 part of n-octanol, 3 parts of inorganic antibacterial agent, 0.6 part of antistatic agent

[0028] The inorganic antibacterial agent is obtained by uniformly stirring and mixing zirconium phosphate, magnesium titanate and magnesium niobate in a mass ratio of 1:1:1.

[0029] The antistatic agent consists of dioctadecylmethyl tertiary amine, octadecylmethyldihydroxyethylammonium bromide, and dodecyltrimethylammonium bromide in a mass ratio of 1:1:1. Stir to mix well.

[0030] Antibacterial acrylic sheet preparation, including the following steps:

[0031] (1) Mix methyl methacrylate and dicumyl peroxide evenly, then heat and polymerize in a water bath at 82°C for 30 minutes, and finally cool to room temperature to obtain a viscous plexiglass prepolymer;

[0032] (2) Mix organic glass prepolymer, aluminum hydroxide, n...

Embodiment 2

[0036] It is basically the same as Example 1, except that the inorganic antibacterial agent is obtained by stirring and mixing magnesium titanate and magnesium niobate at a mass ratio of 1:1. Obtain the antibacterial acrylic sheet material of embodiment 2.

Embodiment 3

[0038] It is basically the same as that of Example 1, except that the inorganic antibacterial agent is obtained by uniformly stirring and mixing zirconium phosphate and magnesium niobate at a mass ratio of 1:1. Obtain the antibacterial acrylic sheet material of embodiment 3.

Abstract

The invention discloses an antibacterial acrylic plate. The antibacterial acrylic plate is prepared from the following raw materials in parts by weight: 98 to 102 parts of methyl methacrylate, 0.1 to 0.7 part of dicumyl peroxide, 18 to 22 parts of aluminium hydroxide, 0.1 to 0.5 part of n-octyl alcohol, 2 to 4 parts of an inorganic antibacterial agent and 0.6 to 1.2 parts of an antistatic agent. The antibacterial acrylic plate provided by the invention is convenient to process and high in construction efficiency, and has excellent antibacterial property, excellent antistatic property, good sensory effect, high weathering resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an antibacterial acrylic plate. Background technique [0002] Acrylic is also called PMMA, which is plexiglass. The chemical name is polymethyl methacrylate. It is an important thermoplastic with good light transmission, electrical insulation, chemical resistance, solvent resistance, and weather resistance. And it has certain heat and cold resistance. After post-processing, it can be applied to liquid crystal light guide plate film, LED lamps, optical fiber materials, optical products, auto parts, home appliance parts, lampshades, billboards, and daily necessities, especially So far, it has the best quality and reasonable price among synthetic transparent materials. It is usually used in lampshades, billboards, etc. Such products usually require heat resistance, oxidation resistance, corrosion resistance, and certain mechanical strength and quality, but the existing polymethyl ...
