Embodiment 1

[0018] After degreasing at high temperature, the non-alkali glass fiber cloth is repeatedly coated with polytetrafluoroethylene emulsion by dipping machine to form anti-adhesive polytetrafluoroethylene glass fiber cloth, and then the polytetrafluoroethylene glass fiber cloth is activated on one side. Double the surface area of ​​the activated surface so that it can be glued in the future. Finally, use a coating machine to coat the activated PTFE glass fiber cloth with silicone self-adhesive. According to different industries, apply different thicknesses of silicone. 50m per roll is a standard package. The polytetrafluoroethylene glass fiber cloth adhesive tape contains 40% non-alkali glass fiber yarn, 53% polytetrafluoroethylene emulsion and 7% organic silica gel.

Embodiment 2

[0020] After degreasing at high temperature, the non-alkali glass fiber cloth is repeatedly coated with polytetrafluoroethylene emulsion by dipping machine to form anti-adhesive polytetrafluoroethylene glass fiber cloth, and then the polytetrafluoroethylene glass fiber cloth is activated on one side. Double the surface area of ​​the activated surface so that it can be glued in the future. Finally, use a coating machine to coat the activated PTFE glass fiber cloth with silicone self-adhesive. According to different industries, apply different thicknesses of silicone. 50m per roll is a standard package. The polytetrafluoroethylene glass fiber cloth adhesive tape contains 50% non-alkali glass fiber yarn, 45% polytetrafluoroethylene emulsion and 5% organic silica gel.

Abstract

The invention discloses a polytetrafluoroethylene glass fiber cloth adhesive tape, which is prepared from 40-50% of alkali-free glass fiber yarn, 45-55% of polytetrafluoroethylene emulsion, and 5-8% of organic silica gel. The polytetrafluoroethylene glass fiber cloth adhesive tape provided in the invention has high insulating property, anti-ultraviolet property, and antistatic property, and various oil stains, dirty spots, or other attachments adhered to the surface of the adhesive tape is easy to clean. The adhesive tape can be used in a temperature range of from a low temperature of -196 DEG C to a high temperature of 300 DEG C, and is resistant to chemical reagents, such as strong acid, strong base, nitrohydrochloric acid, and various organic solvents.

Description

technical field [0001] The invention relates to an insulating tape, in particular to a polytetrafluoroethylene glass fiber cloth adhesive tape. Background technique [0002] PTFE has the characteristics of high and low temperature resistance, anti-sticking and anti-corrosion. The PTFE glass fiber cloth is made into tape, which is widely used in anti-sticking, corrosion-resistant and high-temperature-resistant surface paste; packaging, sealing heat sealing, electronic Insulation and other industries; it can also be used in non-woven drying drums, thermoplastic demoulding and other industries. PTFE fiberglass cloth adhesive tape has the advantages of high temperature resistance, anti-sticking and anti-corrosion. However, the polytetrafluoroethylene glass fiber cloth adhesive tape currently on the market has the following disadvantages due to improper composition and proportioning: [0003] 1. The insulation performance is poor, and it cannot prevent ultraviolet rays and sta...
