Environment-friendly flame-retardant type epichlorohydrin-rubber pipe formula

Abstract

The invention relates to a formula of an environment-friendly flame-retardant type epichlorohydrin-rubber pipe, which comprises the following components in parts by weight: 30-70 parts of epichlorohydrin rubber C, 30-70 parts of epichlorohydrin rubber H, 1-8 parts of age inhibitor RD, 0.5-7.5 parts of age inhibitor MB, 1-7 parts of acid-absorbing agent DHT-4A, 2-10 parts of calcium oxide, 3-9 parts of diantimony trioxide, 7-13 parts of decabromodiphenyl ethane, 5-12 parts of lead-free vulcanizing agent H2, 35-55 parts of fast-extruding carbon black N550 and 1-9 parts of ATBC (Acetyl Tributyl Citrate). The environment-friendly flame-retardant type epichlorohydrin-rubber pipe also comprises 1-7.5 parts of anti-roll-bonding agent SPR 66. The environment-friendly flame-retardant type epichlorohydrin-rubber pipe can achieve the effect of flame retardance and simultaneously has the effect of environmental protection, and environment-friendly requirements in many aspects are met. Moreover, the requirements of European standards are met by the formula, and requirements on the required performances of products are achieved.

Description

technical field [0001] The invention relates to a chlorohydrin rubber tube. In particular, it relates to an environment-friendly flame-retardant chlorohydrin rubber tube formula. Background technique [0002] Rubber materials and products are widely used in various fields of automobile machinery, metallurgy, coal, cement, petrochemical and aerospace. From tires, tapes, hoses, and various rubber parts, the safety and environmental protection requirements of the rubber materials used are getting higher and higher. At present, most of the chlorohydrin rubber formulas commonly used in China use leaded metal oxides. Although the use of leaded metal oxides can have a better degree of crosslinking and thus obtain good heat aging resistance, however, lead metal oxides If the substance is volatilized in a hot environment for a long time, it will also seriously endanger people's life safety. The global formulation of environmental protection clauses mainly focuses on the use of the...
