Formula of environment-friendly flame-retardant hose

Abstract

The invention discloses a formula of an environment-friendly flame-retardant hose. The formula comprises the following raw materials in parts by weight: 100 parts of raw ethylene propylene diene monomer powder, 30-50 parts of high-temperature-resistant epoxy resin, 15-25 parts of fatty oil, 10-15 parts of silica gel powder, 5-10 parts of kieselguhr, 1-3 parts of molybdenum disulfide, 6-14 parts ofmelamine, 3-8 parts of zinc borate, 1-3 parts of zinc hydroxystannate, 0.5-1.5 parts of tetramethyl thiuram disulfide, 0.5-1.5 parts of trimethylolpropane trimethacrylate, 0.25-0.75 part of sulfur, 3-8 parts of polyethylene glycol and 0.3-0.6 part of di-n-octyl tin. The hose formula disclosed by the invention is reasonable in composition, free of phosphorus and halogen, free of pollution to the environment, excellent in flame-retardant effect and less in usage amount; and the prepared hose has good wear resistance, high temperature resistance and impact resistance, the production cost is low,the mixing uniformity of each raw material is good, and the prepared hose has good properties and quality.

Description

technical field [0001] The invention relates to the technical field of rubber hose materials, in particular to a formula of an environment-friendly flame-retardant rubber hose. Background technique [0002] Hose refers to a type of tubular rubber product used to transport gas, liquid, slurry or granular materials. According to the different skeleton layers, it can be divided into full rubber hose, cloth hose, suction hose, braided hose, winding hose, knitted hose and short fiber hose. Most rubber hoses are flammable, and for flammable materials, especially gases or liquids, flammable hoses have certain safety hazards. In order to solve the disadvantages of flammable hoses, a certain amount of resistance is usually added to the material of the hoses. Flame retardants. The flame retardants currently used in hose materials usually contain halogens. However, the hoses that use halogen-containing flame retardants will produce a lot of smoke during the combustion process, which w...

Problems solved by technology

Most rubber hoses are flammable, and for flammable materials, especially gases or liquids, flammable hoses have certain safety hazards. In order to solve the disadvantages of flammable hoses, a certain amount of resistance is usually added to the material of the hoses. Flame retardants, the flame retardants currently used in rubber hose materials usually contain halogens, but the hoses using halogen-containing flame retardants will produce a lot of smoke during the combustion process, which will pollute the environment and do not conform to the concept of environmental protection

China authorized announcement number: CN101463166B discloses a formula of an environmentally friendly flame retardant rubber hose, which does not contain halogen and is more in line with the concept of environmental protection than the traditional halogen-containing flame retardant, but the amount of flame retardant used in this formula is relatively large , which is higher than that of the main material EPDM rubber, which will increase the mixing efficiency of the flame retardant and other raw materials, and will also increase the production cost of the hose
