Abstract
The invention relates to a plasma modified nylon membrane process method. The nylon membrane process method includes the steps that firstly, nylon particles and nanometer materials are adopted to be uniformly mixed with a modified nylon membrane in a stirrer, and the material which is uniformly mixed is added to a twin-screw extruder to be extruded out; secondly, water cooling, material cutting and drying are conducted; thirdly, the modified nylon particles are subjected to blow molding and membrane forming in a blowing machine; finally, plasma treatment under a sub vacuum or a vacuum environment is conducted in a blow molding and membrane forming winding cabin, and the nylon membrane material with the surface activated is obtained. According to the plasma modified nylon membrane process method, the nanometer material is added to nylon, the barrier property and wear resistance of nylon can be effectively improved, meanwhile the surface of the nylon membrane is subjected to plasma treatment in the winding process, the surface energy of the nylon is improved, and the nylon membrane produced under the process has excellent adhesion performance.
Description
Technical field
