Embodiment 1

[0025] Plastic raw materials for white household appliances (parts by weight): 100 parts of polyvinyl chloride resin, 21 parts of tributyl citrate, 16 parts of calcium stearate, 3 parts of flame retardant, and 1.2 parts of antioxidant.

[0026] 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.

[0027] 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.

[0028] Preparation of plastics for white goods:

[0029] Add each component into a high-speed mixer, control the rotation speed at 350 rpm at room temperature, mix for 8 minutes, take it out and transfer it to a twin-screw extruder, the processing temperature of the twin-screw extruder is 240 ° C, an...

Embodiment 2

[0031] 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. The plastic for white household appliances of Example 2 was obtained.

Embodiment 3

[0033] 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. The plastic for white household appliances of Example 3 was obtained.

Abstract

The invention discloses plastic for white household appliances, prepared from the following materials, by weight: 95-105 parts of polyvinyl chloride resin, 15-25 parts of tributyl citrate, 15-25 parts of calcium stearate, 1-5 parts of a flame retardant, and 0.6-1.8 parts of an antioxidant. The plastic for white household appliances uses the type and quantities of inorganic fillers, flame retardants and antioxidants suitable for improving the plastic through reasonable ratio, has improved flame retardancy, aging resistance and strength and is ideal for white household appliances.

Description

technical field [0001] The invention relates to a plastic, in particular to a plastic for white household appliances. 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, and a large amount of toxic gases wi...
