Embodiment 1

[0027] Engineering plastic raw materials (parts by weight) for TV to reduce infrared signal attenuation: 100 parts of PC resin, 10 parts of gallium arsenide, 3 parts of methyl tin mercaptide, 5 parts of carbon black, 3 parts of flame retardant, 1.2 parts of antioxidant share.

[0028] Described flame retardant is 1:1 by mass ratio by three (2-chloroethyl) phosphoric acid esters, phosphoric acid tris (butoxyethyl) esters, phosphoric acid tris (1-chloro-2-propyl) esters: 1 Stir to mix evenly to obtain.

[0029] The antioxidant is composed of N-isopropyl-N-phenyl-p-phenylenediamine, N-cyclohexyl-N'-phenyl-p-phenylenediamine, N,N-di-sec-butyl-p-phenylenediamine Stir and mix uniformly according to the mass ratio of 1:1:1.

[0030] TV sets are made of engineering plastics that reduce infrared signal attenuation:

[0031] Add each component into a high-speed mixer, control the speed at 350 rpm at room temperature, mix for 8 minutes, take it out and transfer it to a twin-screw extr...

Embodiment 2

[0033] Basically the same as Example 1, the only difference is that the flame retardant is stirred by tris (butoxyethyl) phosphate and tris (1-chloro-2-propyl) phosphate in a mass ratio of 1:1 Mix well to get. Obtain the engineering plastics that reduce the attenuation of infrared signals for the TV set of embodiment 2.

Embodiment 3

[0035] Basically the same as Example 1, the only difference is that the flame retardant is stirred by tris (2-chloroethyl) phosphate and tris (1-chloro-2-propyl) phosphate in a mass ratio of 1:1 Mix well to get. Obtain the engineering plastics that reduce the attenuation of infrared signals for the television set of embodiment 3.

Abstract

The invention discloses infrared signal attenuation-reducing engineering plastic for televisions. The infrared signal attenuation-reducing engineering plastic for the televisions is prepared from the following raw materials in parts by weight: 90-110 parts of PC resin, 5-15 parts of gallium arsenide, 1-5 parts of methyl tin mercaptide, 2-8 parts of carbon black, 1-5 parts of a flame retardant, and 0.6-1.8 parts of an antioxidant. Through reasonable proportions, the types and the using amounts of an inorganic filler, the flame retardant and the antioxidant which are suitable for improving the flame retardance, the aging resistance and the strength of the infrared signal attenuation-reducing engineering plastic for the televisions are preferably selected, and the infrared signal attenuation-reducing engineering plastic for the televisions can reduce infrared signal attenuation while visible light is shielded.

Description

technical field [0001] The invention relates to a plastic, in particular to an engineering plastic used for reducing infrared signal attenuation for a TV. Background technique [0002] Since the first artificial synthesis of phenolic resin by German scientist Bayer in 1872, the research and application of polymer materials have developed rapidly, especially plastics have become one of the most important materials and are widely used in various fields of the national economy. With its beautiful appearance, bright colors and low price, plastic products have the advantages of light weight, corrosion resistance, good insulation, high specific strength, simple processing technology and low cost, making them widely used in the home appliance industry. [0003] With the continuous development of science and technology and economy, daily necessities made of plastics play an increasingly important role in daily life. However, plastics are easy to burn, and the burning speed is fast,...
