Description
Technical field
Raw material is configured the present invention relates to a kind of rubber, specifically a kind of fluorubber excellent with fluororesin cohesive is prepared
Raw material.
Background technology
The environmental issue of country is on the rise at present, is further reinforcing Motor Vehicle Pollution Prevention work, is reduced from source
Discharge, Environmental Protection Department fabric study drafts《Automobile-used compression-ignited, gaseous fuel spark-ignition engine and automobile exhaust contaminant
Emission limit and measuring method (Chinese 6th stage)》(exposure draft), the i.e. standard of state six.With the reality of the following standard of state six
Apply, the sebific duct of fluorubber/chlorohydrin rubber structure can not meet emission request in current automotive fuel oil system, and will use fluorine rubber
The additional one layer of fluorine resin film of glue wraps up the structure of chlorohydrin rubber again.
Fluororesin be in molecular structure containing the analog thermoplastic resin for restoring son, it mainly by tetrafluoroethene (TFE),
What vinylidene (VDA), hexafluoroethylene (HFP) were constituted, with excellent oil resistivity, osmotic-pressure-tolerant, anti-flammability and sealing, and
And the product of sandwich construction can be prepared with elastomer using the flexible nature of its protrusion, it is as automobile fuel oil from now on
The optimal selection of tube material.
Because fluorine glue and fluororesin are all high fluoropolymers, fluorine element is that electronegativity is most strong in known chemical element
Element, fluorine atom and the C-F keys bond energy that carbon atom is constituted are very high, and the radius very little of fluorine atom, enable fluorine atom closely
It is arranged in around carbon atom, forms the protective barrier of C-C keys, thus imparts the chemical lazy of fluorubber and fluororesin strand
Property.Therefore, when producing fluorubber with fluororesin product, between the two because chemical inertness causes cohesive bad, take off
Layer phenomenon.The present invention solves fluorubber and the bad problem of fluororesin cohesive, makes fluorine by carrying out special compounding to fluorubber
Rubber and the fuel hose of fluororesin structure can realize productionization, and material has been established to meet future automobile emission regulation demands
Basis.
The content of the invention
The technical problems to be solved by the invention are to provide the fluorubber excellent with fluororesin cohesive.
In order to solve the above technical problems, the technical scheme is that：A kind of and excellent fluorubber of fluororesin cohesive
