Abstract
The invention discloses a method for improving an adhesive property by processing chemigum through a low temperature plasma using argon gas as a medium. The method comprises the steps of: (1) processing the chemigum by using the low temperature plasma in the argon gas medium of which the degree of vacuum is 30-40 pascals; (2) enabling the processing power to be 70-110 watts and the time to be 3-10 minutes; and (3) within 5 hours after processing, using a chemnitz Locke glue adhesion agent (CH205) for adhering the chemigum and polytetrafluoroethylene, and performing vulcanization for 30 minutes at 140-150 DEGC. According to the method disclosed by the invention, the adhesion strength between the chemigum and the polytetrafluoroethylene is improved to at least 500 newtons per metre from 0; the processing method does not generate an influence on the physical mechanical performance of the chemigum.
Description
Technical field
The present invention relates to a kind of surface treatment method of paracril, particularly relate to one argon gas as after treatment media, Low Temperature Plasma Treating paracril, realize the method improving adhesiveproperties.
Background technology
Paracril is the random copolymers macromolecular material that divinyl and vinyl cyanide two kinds of monomers obtain through free radical initiated emulsion polymerization, the sealing under hot environment is used for as specialty elastomer, although be a kind of oil-resistant seal material of excellence, resistance to polarizable medium poor performance.In order to improve resistance to polarizable medium performance further, can be the polytetrafluoroethylene film of 0.1 ~ 0.5 millimeter in its Surface coating a layer thickness.
This technology makes paracril possess the cementability with tetrafluoroethylene.
Summary of the invention
The invention provides a kind of method that argon medium Low Temperature Plasma Treating paracril improves adhesiveproperties, characterization step is as follows:
(1) the bonding paracril of preparation is put into the processing tank of low-temperature plasma equipment, be evacuated to vacuum tightness and be less than 5 handkerchiefs;
(2) pass into the argon gas that purity is at least 99.9%, keep vacuum tightness to be 35 ± 5 handkerchiefs;
(3) loading current and voltage make argon gas low-temperature plasma, process paracril, and processing power is 70 ~ 110 watts, and the treatment time is 3 ~ 10 minutes;
(4) process in latter 5 hours, carry out bonding with the paracril of Kai Muluoke CH205 sizing agent to process with tetrafluoroethylene, and sulfuration 30 minutes at 140 ~ 150 DEG C.
The bonding strength of paracril of the present invention and tetrafluoroethylene brings up to more than 500 Newton/meter, and this treatment process can't affect the physical and mechanical property of paracril.
Advantage of the present invention is: the bonding strength of the paracril and tetrafluoroethylene that do not carry out Low Temperature Plasma Treating is zero; After adopting the inventive method, the bonding strength between paracril and tetrafluoroethylene brings up at least 500 Newton/meter; Method of the present invention, does not affect the physical and mechanical property of paracril simultaneously.
