PTFE (polytetrafluoroethylene) thin film

Abstract

The invention discloses a PTFE (polytetrafluoroethylene) thin film. The PTFE thin film is prepared from components in a raw material formula in parts by weight as follows: 75-95 parts of PTFE, 15-18 parts of polyacrylamide, 7-10 parts of calcium carbonate, 2-3 parts of glass fibers, 3-5 parts of talcum powder, 1-2 parts of silicon dioxide, 1-2 parts of carbon black, 6-8 parts of polyurethane and 13-15 parts of polyimide. With the adoption of the formula with the reasonable ratio, further, new components including the glass fibers, the talcum powder, silicon dioxide, carbon black, polyurethane,polyimide and the like are added to the raw material formula, the ratio of the components is reasonably defined, so that by the aid of the ingenious component ratio, not only is integration of the components greatly improved, but also performance of the components is unexpectedly improved, finally, a product has the advantages of being good in resistance to heat, acid and base, resistant to wear,light, non-toxic, odor-free and the like, and stretching capacity, heat conductivity, corrosion resistance and smoothness of the product are improved dramatically.

Description

technical field [0001] The invention relates to a polymer material, specifically a polytetrafluoroethylene film, belonging to the technical field of chemical materials. Background technique [0002] Plastic film is a kind of film with a wide range of applications, and with the development of society, there are more and more demands for plastic films in all walks of life. Plastic films are mainly used for packaging and laminating, and have been widely used in food , medicine, chemical industry and other fields have brought great convenience to people's life, and polytetrafluoroethylene has good heat resistance and light weight performance, and the market share is also high, so it promotes polytetrafluoroethylene The development of ethylene film technology, especially the PTFE film has good heat resistance, acid and alkali resistance, friction resistance, light weight, non-toxic, odorless and other advantages, so it develops very rapidly. However, the existing PTFE film Vinyl...

[0002] Plastic film is a kind of film with a very wide range of applications, and with the development of society, there are more and more demands for plastic films from all walks of life. Plastic films are mainly used for packaging and laminating, and have been widely used in food , medicine, chemical industry and other fields have brought great convenience to people's life, and polytetrafluoroethylene has good heat resistance and light weight performance, and the market share is also high, so it promotes polytetrafluoroethylene The development of ethylene film technology, especially the PTFE film has good heat resistance, acid and alkali resistance, friction resistance, light weight, non-toxic, odorless and other advantages, so it develops very rapidly. However, the existing PTFE film Vinyl film still has deficiencies due to formula matching, so its stretchability, thermal conductivity, corrosion resistance and smoothness cannot be guaranteed
