Problems solved by technology

The cloth made of glass fiber will make the skin itchy after contact with the human body, and it is also harmful to health
Pre-oxidized yarn and aramid fiber are 80,000 to 300,000 yuan / ton, the price is relatively expensive, pre-oxidized yarn is relatively brittle, and aramid fiber is too strong, so it is difficult to process
Moreover, there is no supply of pre-oxygenated yarn and aramid fiber in China, and they are completely dependent on imports, making it difficult to form a mass production scale.
In addition, the fire-resistant grades of the above-mentioned fireproof materials are only B1, and the fire-resistant performance is poor. For example, glass fibers will melt at a temperature of 600°C, and pre-oxidized silk and aramid fibers will melt at temperatures greater than 260°C and 240°C respectively. It will be carbonized, and it is difficult to meet the occasions with high fire protection and heat insulation requirements

Abstract

The invention relates to fire-proof heat-resistant soft rubber and a preparation method thereof. The fire-proof heat-resistant soft rubber is characterized by being prepared by mixing raw materials comprising chlorinated polyethylene, butadiene-styrene rubber, butadiene rubber, zinc oxide, stearic acid, magnesium oxide, magnesium hydroxide, aluminium hydroxide, white carbon black, diethylene glycol, barium stearate, zinc stearate, 2-thiol benzimidazole, styrenated phenol, antimonous oxide, dicumyl peroxide, triallyl isocyanurate, titanium white, mica powder and the like. The raw materials have low price and sufficient goods sources and are harmless to a human body. Fire-proof cloth and various appliances manufactured by the fire-proof heat-resistant soft rubber have high fire resistance and can be used in the occasion with high fire-protection requirement.

Description

technical field [0001] The invention relates to a fireproof material and a preparation method thereof. Specifically, it is a preparation method of a fire-proof and heat-resistant soft rubber with fire-proof performance. Background technique [0002] As we all know, no matter in the industrial field or in the field of daily life, in order to avoid the occurrence of fire, fire prevention will be involved, and refractory materials are required. Traditional refractory materials include asbestos, glass fiber, pre-oxidized wire and aramid fiber, etc. These materials can be used to make fireproof cloth or various appliances to meet the fireproof requirements of different industries. Among them, asbestos is easy to cause cancer after contact with the human body, and has been banned by countries all over the world. The cloth made of glass fiber will make the skin itchy after contact with the human body, and it is also harmful to health. The price of pre-oxidized yarn and aramid fi...
