preparation example Construction

[0017] A preparation method of polytetrafluoroethylene fiberglass cloth adhesive tape, comprising the steps of:

[0018] a. After the alkali-free glass fiber layer is degreased at high temperature, it is repeatedly coated with polytetrafluoroethylene emulsion through a dipping machine, and then dried to obtain polytetrafluoroethylene glass fiber cloth;

[0019] B, the polytetrafluoroethylene fiberglass cloth that obtains in step a is carried out one-sided surface activation treatment, carries out the coating of organic silica gel on the activated surface after the treatment, dries after gluing and obtains polytetrafluoroethylene fiberglass cloth adhesive tape .

[0020] The polytetrafluoroethylene emulsion in the step a includes 60-70% polytetrafluoroethylene, 20-30% deionized water and 5-10% flame retardant.

Embodiment 1

[0022] The alkali-free glass fiber cloth is degreased under high temperature conditions, and the degreased alkali-free glass fiber cloth is repeatedly coated with polytetrafluoroethylene emulsion through a dipping machine. The polytetrafluoroethylene emulsion includes 60% polytetrafluoroethylene, 30% degreased Ionized water, 10% halogen-free flame retardant, and polytetrafluoroethylene emulsion are repeatedly coated on the surface of the alkali-free fiber cloth and dried to obtain an anti-adhesive polytetrafluoroethylene glass fiber cloth; the polytetrafluoroethylene glass fiber cloth Activation treatment is carried out on one side, so that the surface area of ​​the activated surface is doubled for glue coating, and the activated PTFE glass fiber cloth is coated with silicone self-adhesive on the coating machine, and it is used according to different industries According to the requirements, the organic silica gel with different glue thickness is coated and dried, and finally t...

Abstract

The invention discloses a polytetrafluoroethylene glass fiber cloth adhesive tape and a production method thereof and belongs to the technical field of insulating adhesive tapes. The polytetrafluoroethylene glass fiber cloth adhesive tape comprises an alkali-free glass fiber layer, a polytetrafluoroethylene layer applied to the alkali-free glass fiber layer and an organic silicone layer applied to the surface of the polytetrafluoroethylene layer; the alkali-free glass fiber layer accounts for 40-50% of total weight of the adhesive tape, the polytetrafluoroethylene layer accounts for 45-55% of the total weight of the adhesive tape, and the organic silicone layer accounts for 5-8% of the total weight of the organic silicone layer. The polytetrafluoroethylene glass fiber cloth adhesive tape produced herein has high insulation and good ultraviolet resistance and static resistance, can be used normally in a temperature range of -196 DEG C to 300 DEG C, is widely applicable, can meet uses under special conditions, is good in chemical corrosion resistance, can tolerate corrosion by strong acids and alkalis, nitrohydrochloric acid and various organic solvents, and has good flame retardancy, improving safety.

Description

technical field [0001] The invention relates to the technical field of insulating tapes, in particular to a polytetrafluoroethylene glass fiber cloth adhesive tape and a preparation method thereof. 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 adhesive tape, which is widely used in anti-sticking, corrosion-resistant and high-temperature-resistant surface sticking, such as packaging, sealing heat sealing, electronic Insulation and other industries; it can also be used in non-woven drying drums, thermoplastic demoulding and other industries. Due to the characteristics of PTFE, the PTFE glass fiber cloth adhesive tape has the advantages of high temperature resistance, anti-sticking, and anti-corrosion. But, the polytetrafluoroethylene fiberglass cloth sticky tape on the market has the following disadvantages: [0003] 1. The insulation performance is ...
