AI Technical Summary

Problems solved by technology

Its cortex components are polyethylene, rubber-plastic elastic composite materials, polyurethane elastic composite materials, or polyester elastic composite materials. From this, it can be inferred that its flame retardancy is average. The main PP itself is flammable, and it generates a large amount of heat when burned. The speed is fast, and it is also accompanied by the droplet phenomenon, which poses a safety hazard

Abstract

The invention provides a preparation method of a high-flame-retardant material for polyester gauze, which is characterized in that the formula of the high-flame-retardant material comprises polypropylene, polyethylene, polyethylene glycol terephthalate, a flame retardant, a surfactant, an antioxidant, an anti-dripping agent, a lubricant and a flame retardant compound. Nano aluminum powder and fused quartz are adopted as flame retardant complexing agents to be compounded with the flame retardant to form the novel flame retardant, the flame retardant effect is good, the heating rate of the material is slowed down, and the combustion is hindered. When the nano aluminum powder is used as a flame retardant complexing agent, the use amount of the nano aluminum powder is small, the nano aluminum powder covers the surface of a material, when a fire disaster occurs, the nano aluminum powder can rapidly transfer heat due to high temperature and is subjected to an oxidation reaction to generate aluminum oxide and smoke, the aluminum oxide plays a role of a physical barrier, can insulate heat and oxygen, and inhibits combustible gas from flowing to a matrix, and the flame-retardant effect is achieved.

Description

technical field [0001] The invention relates to the field of window screen production and processing, in particular to a preparation method for a high flame-retardant material used for polyester gauze. Background technique [0002] At present, the window screen products on the market are mainly glass fiber window screens. Fiberglass window screening is formed by weaving glass fibers coated with polyvinyl chloride (PVC) coating. Due to the poor heat resistance of PVC materials, it is easy to decompose at high temperature to produce hydrogen chloride gas, which will cause great harm to the human body; and the weather resistance of PVC materials is poor, easy to age, and has a short service life; at the same time, when PVC materials are burned, they will also produce dioxins, which have great Strong carcinogenicity. Therefore, it is imperative to develop a new generation of window screen substitutes. Polypropylene is one of the most commonly used general-purpose plastics. It...
