Abstract

The invention relates to the field of automobile hoses and particularly relates to a CSM composite hose. The CSM composite hose comprises the following components in parts by mass: 45 parts of nitrile rubber, 55 parts of CSM, 72 parts of carbon black, 3 parts of calcium hydroxide, 4 parts of magnesium oxide, 4 parts of an acid acceptor, 2 parts of a rubber releasing agent, 25 parts of a plasticizer, 3 parts of an antiager, 1 part of triallyl isocyanurate and 2 parts of a vulcanizing agent. According to the CSM composite hose and a production method thereof, the hose produced according to the method is vulcanized for 20min at 170 DEG C; after the hose is aged in hot air at 120 DEG C for 70h, the hardness change value is 3 degrees, the intensity change value is +11%, and the elongation change value is -14%; and after the hose in immersed in NO.3 oil at 120 DEG C for 70h, the volume change value is +58%. Therefore, the CSM composite hose has favorable heat resistance and oil resistance.

Description

technical field [0001] The invention relates to the field of rubber hoses for vehicles, in particular to a CSM composite rubber hose and a production method thereof. Background technique [0002] The fuel filler hose of existing diesel vehicles uses NBR rubber hose inside and CSM composite rubber hose for outsourcing. However, due to the defects of the existing formula of the two rubber materials, it is difficult to bond the two rubber materials, and the bonding firmness is poor. In the process of use, it is easy for the two rubber materials to separate, which will cause the safety of diesel vehicles. Contents of the invention [0003] The object of the present invention is to provide a kind of CSM composite rubber hose and its production method in order to solve the deficiency of above-mentioned technology, the CSM rubber hose and NBR rubber hose produced by this method are well bonded, and the firmness of bonding is high. [0004] In order to achieve the above object, t...
