Abstract

The invention relates to anti-dazzle fire-resistance polycarbonate and a preparation method thereof, which belong to the field of fire-resistance polycarbonate. The anti-dazzle fire-resistance polycarbonate comprises the following ingredients: 10 to 95 parts of polycarbonate, 10 to 85 parts of high-viscosity high-melt-point large-grain-diameter polycarbonate grains, 1 to 20 parts of fire-resistance agents, 0.1 to 8 parts of ultraviolet absorbents, 0.1 to 6 parts of antioxidizers and 0.1 to 5 parts of demolding agents. The high-viscosity high-melt-point large-grain-diameter polycarbonate grains consist of the following ingredients: 100 parts of polycarbonate, 0.1 to 5 parts of cross linking agents and 0.1 to 0.3 part of antioxidizers. The anti-dazzle fire-resistance polycarbonate of the invention has the advantages of light transmission, non-transparency, nebulous and unique patterns, naturalness and non-repeated effect of ice glass, has the effects of dazzle elimination and fire resistance, and has good heat resistance performance, ultraviolet resistance, excellent mechanical property, repeated dismounting and installation, and freely carrying and transportation.

Description

technical field [0001] The invention relates to an anti-glare and flame-retardant polycarbonate and a preparation method thereof, which belong to the field of flame-retardant polycarbonate, and are especially mainly used in decorative lighting fixture covers, handicrafts, building materials and the like. Background technique [0002] Polycarbonate is usually selected as the cover material of high-quality lighting fixtures. Its advantages are: the mechanical strength is the largest among polymer materials, and it is known as bulletproof rubber. Its high temperature resistance, flame retardancy, transparency, non-toxic And other comprehensive properties are unmatched by other polymer materials. Although polycarbonate lampshades have the above-mentioned advantages, with the continuous improvement of people's living standards, people are not only satisfied with the needs of applicability and safety, but also for comfort. , decoration, taste and beauty enjoyment requirements are ...
