Problems solved by technology

[0003] Fluorine resin is a composition of tetrafluoroethylene (TFE), vinylidene fluoride (VDA) and hexafluoroethylene (HFP), which has excellent oil resistance, permeation resistance, flame retardancy and sealing performance, but due to its internal components The bond energy between the fluorine atom and the carbon atom is very high, and the radius of the fluorine atom is very small, so that the fluorine atom can be closely arranged around the carbon atom, forming a protective barrier fo

Abstract

The invention discloses an adhesive anti-falling rubber formula. Adhesive anti-falling rubber is prepared from, by weight, 100 parts of nitrile butadiene rubber 4155, 5-10 parts of active magnesium oxide MgO150, 1-2 parts of an anti-aging agent RD, 1-2 parts of stearic acid, 1-2 parts of DBU formate, 35-50 parts of carbon black N550, 10-25 parts of carbon black N774, 15-30 parts of silicon powder750, 10-20 parts of a plasticizer RS107, 1-2 parts of sulphur S-80GE, 1-2 parts of an accelerant CZ and 0.5-1.0 part of an accelerant DM. The adhesive anti-falling rubber formula has the advantages that the formula taking the butadiene-acrylonitrile rubber as a base material maintains the excellent performance of the nitrile butadiene rubber, the adhesive strength with fluororesin THV 815 is greater than or equal to 3.0 N/mm, and the technical problem that delaminating can occur when rubber is bonded to the fluororesin in the prior art is solved.

Description

Technical field [0001] The invention relates to a rubber formula, in particular to an adhesive and anti-shedding rubber formula. Background technique [0002] Due to the stricter national environmental protection standards, the piping materials of the automobile fuel system are also required to be upgraded. In the future, the performance of the fuel system piping in terms of penetration resistance needs to be greatly improved. With the gradual implementation of the National VI regulations, by 2020, nationwide All domestic cars are required to meet the national six emission regulations and standards. Automobile emissions include: hydrocarbons, nitrogen oxides, sulfur oxides, and the emissions of hydrocarbons are closely related to automobile fuel lines. The source of hydrocarbon emissions in the fuel system is mainly leakage. The traditional NBR / PVC (nitrile rubber, polyvinyl chloride alloy rubber), FKM (fluorine rubber) + ECO (chlorohydrin rubber) structural hose can no longer m...
