preparation example Construction

[0021] A method for preparing a fireproof polymer composite material, comprising the following steps in sequence:

[0022] Step 1. Mix the silane hydrolyzate, styrene, acrylonitrile, and polymerization initiator uniformly according to the required ratio, then add 1,3-butadiene, and polymerize at 85–95°C until the system viscosity reaches 200– Dry after 300cp to obtain organosilicon / polymer hybrid material;

[0023] Step 2: Mix the organosilicon / polymer hybrid material and additives obtained in Step 1 evenly according to the required ratio, and then put them into an extruder to extrude and granulate.

[0024] In step one, the preparation method of the silane hydrolyzate is:

[0025] Stir the silane and water according to the required ratio first, then add the catalyst and stir until the system is clear and transparent.

[0026] In step 2, the extrusion process of the extruder is: 180±5°C in the first zone, 200±5°C in the second zone, 220±5°C in the third zone, 230±5°C in the ...

Abstract

The invention discloses a fireproof polymer composite material, which comprises the following raw materials: 80-100 parts of organic silicon / polymer hybrid materials and 0.6-1.0 part of an auxiliary agent, wherein raw materials of the organic silicon / polymer hybrid materials comprise 10-13 parts of silane hydrolysates, 5-8 parts of styrene, 5-8 parts of acrylonitrile, 5-8 parts of 1,3-butadiene and 0.2-0.6 part of a polymerization initiator, wherein raw materials of the silane hydrolysates comprise 0.6-0.8 part of silane, 1-3 parts of catalysts and 2-4 parts of water; and the silane comprisesvinylphenyl diethoxysilane. During preparation, the silane hydrolysates, the styrene, the acrylonitrile, and the polymerization initiator are mixed evenly according to the required ratio, then the 1,3-butadiene is added, the mixture is polymerized at 85-9 DEG C until the system viscosity reaches 200-300 cp, and then the mixture is dried to obtain the organic silicon / polymer hybrid material, and the organic silicon / polymer hybrid material is mixed with the auxiliary agent, extruded and granulated. The material has good flame retardant performance.

Description

technical field [0001] The invention belongs to the field of organic polymer composite materials, and in particular relates to a fire-resistant polymer composite material and a preparation method thereof. The material is an environmentally friendly fire-resistant polymer engineering plastic and is mainly used as a vehicle material. Background technique [0002] In recent years, electric bicycles, electric motorcycles, electric tricycles and other electric vehicles have gradually become an important tool for people to travel because of their economical and convenient characteristics, and the number of vehicles has grown rapidly. However, due to insufficient safety technical standards, inadequate market supervision, and outstanding storage and charging problems, electric vehicle fire accidents occur frequently, causing heavy losses to the lives and property of the people. Electric vehicles all use plastic shells. Once they spontaneously ignite, the plastic shells will burn and...
