Problems solved by technology

Although the flame retardancy of plastics is improved by adding flame retardants, it is obviously not enough to improve the flame retardancy of plastics only by adding flame retardants. Engineering plastics have high requirements for flame retardancy, so it is urgent It is necessary to develop a kind of engineering plastic with higher flame retardancy to solve the problem of insufficient flame retardancy of the above-mentioned engineering plastics

Abstract

The invention discloses a fire-resistant engineering plastic, and belongs to the technical field of plastic material preparation. The fire-resistant engineering plastic is prepared from polycarbonate,organic modified montmorillonite, a modified flame retardant, nano silica, glass fibers, a light stabilizer 770, polyethylene glycol, N,N-ethylene bis-stearamide, white carbon black, di(2,3-dichloropropyl)octyl phosphate, tri(neoamylic dialcohol phosphate)methylamine, silsesquioxane, vinyltriethoxysilane and phosphonitrilic chloride trimer. The fire-resistant engineering plastic is prepared by preparing a base material, preparing a modified material and then mixing the main material and the modified material. The prepared engineering plastic has excellent fire resistance.

Description

technical field [0001] The invention belongs to the technical field of plastic material preparation, and in particular relates to a fire-resistant engineering plastic and a preparation method thereof. Background technique [0002] Engineering plastics refer to industrial plastics used as industrial parts or housing materials. They are plastics with excellent strength, impact resistance, fire resistance, hardness and aging resistance. The Japanese industry defines it as a high-performance plastic that can be used as a structural and mechanical part, with a fire resistance above 100°C, and is mainly used in industry. Conventional types of engineering plastics include polycarbonate, polyacetal, denatured polyphenylene ether, polyester, polyphenylene sulfide, and the like. The vast majority of plastics are flammable substances, and plastic building materials, transportation materials, household appliances materials, etc. require plastic products to be non-combustible and have g...
