Problems solved by technology

However, due to the poor performance of polypropylene in low temperature environment, there is a problem of post-crystallization during blistering, which leads to uneven molding in all directions, poor plasticity, and difficulty in blistering. Therefore, the existing polypropylene sheet materials on the market are often unable to It meets the requirements of blister molding and the use requirements in low temperature environment, and has poor fire resistance

Embodiment 1

[0026] Antibacterial and flame-retardant surface layer raw materials (parts by weight): 100 parts of PP resin, 8 parts of aluminum hydroxide, 20 parts of linear low-density polyethylene, 3 parts of inorganic antibacterial agent, and 0.6 part of antistatic agent.

[0027] 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.

[0028] 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.

[0029] Preparation of antibacterial and flame-retardant surface layer: Mix PP resin, aluminum hydroxide, linear low-density polyethylene, inorganic antibacterial agent, and antistatic agent to a uniform state, and prepare an antibacterial and flame-retardant surface layer with a thickness of 0.5mm through an extruder.

Abstract

The invention discloses an antibacterial flame-retardant polypropylene board which comprises an antibacterial flame-retardant surface layer. The antibacterial flame-retardant surface layer is prepared from, by weight, 95-105 parts of PP resin, 3-13 parts of aluminum hydroxide, 15-25 parts of linear low-density polyethylene, 2-4 parts of inorganic antibacterial agent and 0.5-1.5 parts of antistatic agent. The antibacterial flame-retardant polypropylene board is convenient to process, high in construction efficiency, good in sensory effect and long in service life and has good antibacterial and antistatic effects and long-term weather resistance.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an antibacterial and flame-retardant polypropylene plate. Background technique [0002] Polypropylene sheet is odorless, non-toxic and tasteless in line with national health standards. It has low density and is the lightest of general-purpose plastics. It can be used without deformation for a long time at a temperature of 100 ° C. It also has excellent electrical insulation properties and chemical stability. , hardly absorbs water, and has no effect in contact with most chemicals. Polypropylene sheet has excellent chemical resistance, heat resistance and impact resistance, and is currently one of the most environmentally friendly engineering plastics. Polypropylene sheet can be used in acid and alkali resistant equipment, environmental protection equipment, waste water and exhaust gas discharge equipment, washing tower, clean room, semiconductor factory and related industrial e...
