Problems solved by technology

[0005] However, many flame-retardant plastic formulations now produce toxic gases when the material is pyrolyzed, causing fire poisoning gas and smoke, which have side effects of suffocation on the human body, seriously damaging people's physical and mental health, and the environmental performance is not ideal, so now people will use more Focus on the development, production and application of new non-toxic, smoke-free and pollution-free environmentally friendly flame-retardant plastics

Abstract

The invention belongs to the field of organic polymer composite materials, and especially relates to a flame resistant plastic and a preparation method thereof. The flame resistant plastic comprises following ingredients, by weight: 50 to 70 portions of polyvinyl chloride resin, 20 to 40 portions of polypropylene, 0.5 to 2 portions of glass fibre, 1 to 5 portions of a fire retardant, 10 to 20 portions of butylated hydroxytoluene, and 15 to 30 portions of diethyl phthalate. The formula of the flame resistant plastic is reasonable; preparation technologies are simple; and the flame resistant plastic possesses flame resistance, is friendly to the environment, and is suitable for large-scaled production.

Description

[0001] technical field [0002] The invention relates to an organic polymer composite material, in particular to a flame-retardant plastic and a preparation method thereof. [0003] Background technique [0004] At present, plastics are used in various fields of industry, agriculture and life. In 1999, the total amount of major thermoplastics (PP, PVC, PS, LDPE, HDPE) in the world reached 110 million tons, and the average annual growth rate reached 5.2%. The number of plastics used in the electrical and electronic industries in Western Europe has reached 23 million tons. At the same time, the application of flame-retardant plastic formulations is becoming more and more extensive. Combustible plastic formula. 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-reta...
