Abstract
A method for bonding teflon comprises the steps that (1) in the argon medium with a 60 Pa vacuum degree, low-temperature plasma is used for treating teflon; (2) processing power is 50-100 W, and time is 10-20 seconds; (3) in 8 hours after treatment, the teflon and fluorinated silicone rubber are bonded through Chemlok 602 adhesive, and solidification is carried out for 30 minutes at 160 DEG C. The method enables the peel strength of the teflon to be improved to 200 N/m from zero.
Description
Technical field
The present invention relates to a kind of bonding polytetrafluoroethylene (PTFE) method, after particularly relating to a kind of Low Temperature Plasma Treating polytetrafluoroethylene (PTFE), realize carrying out bonding method to it.
Background technology
Polytetrafluoroethylene (PTFE) has excellent medium-resistance, but cementability is too poor and cannot carry out bonding with other material.Make polytetrafluoroethylene (PTFE) have adhesive property, it can be improved the medium-resistance of encapsulated material as clad.This technology makes polytetrafluoroethylene (PTFE) possess cementability.
Summary of the invention
The object of the present invention is to provide a kind of method of bonding polytetrafluoroethylene (PTFE), after the method adopts Low Temperature Plasma Treating polytetrafluoroethylene (PTFE), then carry out bonding.
The present invention is achieved like this, and it is characterized in that the step of Low Temperature Plasma Treating polytetrafluoroethylene (PTFE) is:
(1) treatment box that bonding polytetrafluoroethylmaterial material puts into low temperature plasma equipment is carried out in preparation, being evacuated to vacuum is 2Pa;
(2) passing into argon gas, is 60Pa to vacuum;
(3) loading current and voltage carry out low temperature plasma to argon gas, process polytetrafluoroethylene (PTFE), and processing power is 50-100 watt, and the processing time is 10-20 second;
(4) polytetrafluoroethylene (PTFE) after process, within the as far as possible short time, (being no more than 8 hours) carries out bonding;
(5) polytetrafluoroethylene (PTFE) crossed Low Temperature Plasma Treating with Chemlok 602 glue and fluorosioloxane rubber carry out bonding, and 160 DEG C of solidifications 30 minutes.
Advantage of the present invention is: the polytetrafluoroethylene (PTFE) not carrying out Low Temperature Plasma Treating, is zero substantially with the adhesive strength of fluorosioloxane rubber; And adopting the inventive method, the peel strength of polytetrafluoroethylene (PTFE) and fluorosioloxane rubber is greater than 200 Newton/meter or 0.2 kilograms per centimeter.
