Flame retardant plastic for wiring box, and preparation method thereof

Abstract

The present invention discloses a flame retardant plastic for a wiring box, wherein the components comprise, by weight, 70-80% of a PVCSG-8 resin, 1.5-2.5% of a stabilizer, 1-2% of a ACR-ZB-401 PVC processing aid, 0.1-0.2% of titanium dioxide powder, 0.5-0.8% of stearic acid, 0.2-0.4% of PE wax, 0.01-0.02% of a whitening agent OB, 15-25% of calcium powder, and 1-2% of dioctyl oil. The present invention further discloses a preparation method of the flame retardant plastic, wherein the preparation method comprises crushing the components into powder, pouring the powder into a mixing device according to a certain ratio, uniformly stirring, and heating to a temperature of 130-160 DEG C. According to the present invention, the household wiring box made from the flame retardant plastic of the present invention has advantages of no toxicity, low cost, and good flame retardant performance.

Description

technical field [0001] The invention belongs to the technical field of homopolymers or copolymers of vinyl chloride, and in particular relates to a flame-retardant plastic used in junction boxes and a preparation method thereof. Background technique [0002] Plastic material is a material with good performance. Because plastic has the advantages of light weight, no rust, and good insulation, it is used in many links in the production of many products, and the application of flame-retardant plastic formulations is becoming more and more extensive. Most of the current flame-retardant plastic formulas are flame-retardant polymers, which are not easy to ignite, which can reduce accidental fires, or after ignition, there is basically no flame, which can prevent the fire from becoming larger. In addition, flame-retardant plastic formulas can also reduce flames. Propagation speed and burning speed. At present, most of the flame-retardant plastics used for junction boxes on the mark...

[0002] Plastic material is a material with good performance. Because plastic has the advantages of light weight, no rust, and good insulation, it is used in many links in the production of many products, and the application of flame-retardant plastic formulations is becoming more and more extensive. Most of the current flame-retardant plastic formulas are flame-retardant polymers, which are not easy to ignite, which can reduce accidental fires, or after ignition, there is basically no flame, which can prevent the fire from becoming larger. In addition, flame-retardant plastic formulas can also reduce flames. Propagation speed and burning speed. At present, most of the flame-retardant plastics used for junction boxes on the market are made of high-strength imported PC fire-resistant and high-temperature flame-resistant materials. Among them, the flame-retardant materials are mainly brominated flame retardants. Due to bromine Flame retardants will produce a large amount of toxic and harmful gases containing bromine during the combustion process, which will bring great harm to human health.
