Problems solved by technology

Among them, the natural rubber lining fire hose is an economical product traditionally used, which has the advantages of pressure resistance, wear resistance, corrosion resistance, impermeability, and small water resistance, but the disadvantage is that it is not resistant to weather aging and has a short service life; ethylene-propylene rubber lining The above-mentioned performance of the fire hose is better than that of the natural rubber lining fire hose, and it has good weather resistance and long service life, but it is difficult to bond with the synthetic fiber weave, and the investment in the production line is large, the technical requirements are high, and the price is low. It is also more expensive, so it is not conducive to popularization and use; polyurethane rubber-lined fire hose has excellent comprehensive performance. In addition to all the advantages of rubber hose, it also has excellent high pressure resistance, oil resistance, weather resistance, corrosion resistance, and bending resistance. , and light weight, soft and convenient to use, high and low temperature resistance performance is excellent, but the price is also very expensive

Abstract

The invention discloses an environment-friendly and flame retarded rubber material of an inside liner of a fire hose and a preparation method thereof. The rubber material is prepared from the following raw materials in parts by weight: 100 parts of chlorinated polyethylene rubber, 10-15 parts of magnesium oxide, 0-8 parts of zinc oxide, 2-10 parts of thermal stabilizer, 15-20 parts of carbon black, 15-30 parts of white carbon black, 10-20 parts of citric acid plasticizer, 60-100 parts of aluminium hydroxide, 2-8 parts of adhesive, 2-5 parts of vulcanizing agent and 1.5-3 parts of co-vulcanizing agent. The method comprises the following steps of: placing the chlorinated polyethylene rubber, the thermal stabilizer, the magnesium oxide, the zinc oxide, the carbon black, the white carbon black, the aluminium hydroxide, the adhesive and the citric acid plasticizer into an internal mixer, mixing for 120-240 s, then adding the vulcanizing agent and the co-vulcanizing agent to continuously mix for 30-60 s, complementally mixing for 200-400 s on an open mill after discharging, and then pressing into sheet rubber suitable for processing on a tablet press.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to an environment-friendly, flame-retardant fire hose inner lining rubber material and a preparation method thereof. Background technique [0002] The fire hose is a kind of hose used to transport water or foam mixture for fire extinguishing in fire facilities. It uses high-strength synthetic fibers as the weave layer and rubber as the lining. Its performance mainly depends on the rubber lining. The requirements of the fire hose are: corrosion resistance, wear resistance, high pressure resistance, impervious to water, no mildew, easy to coil, soft and light, and weather-resistant. At present, the rubber lining materials of fire hoses produced in China mainly include natural rubber, ethylene propylene rubber and polyurethane rubber. Among them, the natural rubber lining fire hose is an economical product traditionally used, which has the advantages of pressure resistance, we...
