Description

A kind of bonding anti-dropout rubber compounding
Technical field
The present invention relates to a kind of rubber compounding, specifically a kind of bonding anti-dropout rubber compounding.
Background technique
Due to the severization of national environmental standard, the piping material of automotive fuel oil system also requires to upgrade, the following Fuel System Performance needs of the road under the overall leadership in terms of resistance to infiltration are greatly enhanced, complete to the year two thousand twenty with the gradually implementation of six regulation of state Automobile, which requires, within the scope of state meets six emission regulation standard of state.Vehicle emission amount includes: hydrocarbon, oxynitrides, Oxygen sulfur compound, and with automobile fuel oil pipeline it is closely bound up be hydrocarbon discharge.Hydrocarbon is arranged in fuel system Putting source is mainly infiltration leakage, traditional NBR/PVC(nitrile rubber, polyvinyl chloride alloy rubber), FKM (fluorubber)+ECO (chlorohydrin rubber) structure sebific duct can no longer meet harsh six emission request of state.Nitrile rubber (NBR) is as a kind of oil resistant, resistance to The preferable synthetic rubber of aging, the composite construction (NBR/THV/NBR/CSM) with fluororesin (THV) is added as vehicle fuel The direction of note pipe and canister evaporation tube.
Fluororesin be tetrafluoroethene (TFE), vinylidene (VDA), hexafluoroethylene (HFP) constituent, have it is excellent Oil resistivity, osmotic-pressure-tolerant, anti-flammability and leakproofness, but due in its internal composition the bond energy of fluorine atom and carbon atom it is very high, And the radius very little of fluorine atom, enables fluorine atom to be closely spaced around carbon atom, forms the protective barrier of C-C key, this Sample just imparts the higher chemical inertness of fluororesin.Nitrile rubber is to be formed by butadiene and acrylonitrile through emulsion polymerization, usually In the case of vulcanized using sulphur system, therefore, when producing nitrile rubber and fluororesin product, due to the chemical inertness of fluororesin With the difference of vulcanization characteristics, common rubber compounding will appear delamination when bonding with fluororesin, be unable to reach industrialization Purpose.In order to enable rubber and fluororesin to reach enough adhesive strengths, by lot of experiment validation, DBU formic acid is found Salt can promote the adhesive force of the two, and DBU formates is a kind of bicyclic amidine compound, can generate the work of nitrogen at high temperature Free love base, allows fluororesin to connect with nitrile rubber by way of bridge formation, achievees the purpose that chemical crosslinking.The present invention is logical It crosses and nitrile rubber is cooperated using adhesive DBU formates, while keeping nitrile rubber excellent properties, solve fourth The delamination problems of nitrile rubber and fluororesin make nitrile rubber and the product of fluororesin structure can be realized industrialization, and this group Structure cost performance with higher is closed, for the material selection for meeting six emission regulation vehicle fuel filler pipe of state and canister evaporation tube Good basis is established.
For this purpose, applicant proposed a kind of new technical solutions, and provide a kind of and excellent fourth of fluororesin adhesiveness Nitrile rubber formula.
