Abstract
The invention relates to a formula of an environment-friendly flame retardant hose, which comprises the following compositions and weight portions: 100 portions of ethylene propylene diene rubber, 20 portions to 40 portions of fast extruded carbon black, 40 portions to 60 portions of calcined clay, 120 portions to 160 portions of aluminiumhydroxide, 5 portions to 10 portions of zinc borate, 10 portions to 20 portions of antimonytrioxide, 0.5 portion to 0.8 portion of thiuram tetrasulfide, 1.5 portions to 2.0 portions of zinc dibutyl dithiocarbamate, 0.5 portion to 0.8 portion of tetramethyl thiuram disulfide, 3 portions to 5 portions of zincoxide, 1 portion to 3 portions of stearic acid, 1 portion to 3 portions of polyethylene glycol, 1.5 portions to 2.0 portions of morpholine disulfide, 0.3 portion to 0.6 portion of sulfur and 20 portions to 40 portions of paraffin oil. Compared with the traditional product, the invention has the tensile strength of physical and mechanical property of 14MPa, which is higher than the traditional formula by 1.5 times. The invention can obtain FV-0 grade of vertical burn of national standard of flame resistance, namely the requirements of nonflammable material, can achieve the same flame resistant effect with the traditional method and meet the requirements of environment protection and safety of the hose of the modern automobile.
Description
technical field [0001] The invention relates to the technical field of rubber hoses, in particular to the formula of environment-friendly flame-retardant rubber hoses. Background technique [0002] Flame retardant hose mainly refers to the cold air hose used in automobiles. The hose is a full hose, that is, only one layer of rubber, and the material is ethylene propylene dienemonomer (EPDM for short). The cold air hose of the car works in a high temperature and flammable environment, so its flame retardant performance is very important. Since the main chain of most rubbers contains a large amount of carbon, hydrogen, oxygen and other elements, it is easy to generate combustible gas when heated and melted, and it is easy to burn with oxygen at high temperature. In order to achieve the purpose of flame retardancy, the traditional method is to use halogen-containing polymers and add a large amount of halogen-containing flame retardants. However, once a fire breaks out, the p...
