Embodiment Construction

[0027] Below in conjunction with specific embodiment, the present invention is further elaborated:

[0028] A polytetrafluoroethylene glass fiber breathable varnish formula, the mass ratio of each component is as follows: the polytetrafluoroethylene content is 30 ~

[0029] 40%; surfactant 0.5 ~ 0.8%, the balance is deionized water and base cloth.

[0030] The warp and weft density of the base fabric of the PTFE glass fiber breathable tarpaulin is: 200 threads / 10cm

[0031] (±10%), thickness: 0.04 mm ~ 0.06 mm, width: 900 ~ 1000 mm of alkali-free glass cloth.

[0032] Preferably, the mass ratio of each component is as follows: polytetrafluoroethylene content is at 35%; surfactant 0.65%, balance is none

[0033] Ionized water and non-alkali glass cloth with warp and weft density: 200 threads / 10cm, thickness: 0.05mm, width: 950mm.

[0034] Thickness of PTFE glass fiber breathable varnished cloth: 0.05 mm to 0.07 mm, width: 900 to 1000

[0035] mm, the PTFE glass fiber breath...

Abstract

The invention discloses a formula of polytetrafluoroethylene glass fiber breathable varnished cloth. The formula is characterized by consisting of the following components in percentage by mass: 30 to 40 percent of polytetrafluoroethylene, 0.5 to 0.8 percent of a surfactant and the balance of non-ionic water and alkali-free glass cloth of which the warp density and the weft density are 200 pieces per 10 centimeters (+ / -10 percent), the thickness is 0.04 to 0.06mm and the breadth is 900 to 1,000mm. The polytetrafluoroethylene glass fiber breathable varnished cloth has the beneficial effects that by customization of a piece of glass fiber base cloth, the formula and the production technology are improved, so that the alkali-free glass cloth is uniformly coated with and immersed by polytetrafluoroethylene emulsion, and the formula is more reasonable; no bubbles are produced on the surface of the prepared polytetrafluoroethylene glass fiber breathable varnished cloth, and the glue content is uniform; the breathability is high, and the production cost is low; the polytetrafluoroethylene glass fiber breathable varnished cloth has high-temperature resistance and high intensity of a glass fiber fabric and also has a series of properties of high insulation performance, high viscosity prevention and the like of polytetrafluoroethylene.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a polytetrafluoroethylene glass fiber breathable [0002] Linoleum and formula. Background technique [0003] Glass fiber cloth has the advantages of high strength, stable size, high temperature resistance, good corrosion resistance and high filtration efficiency, but [0004] Glass fiber also has obvious disadvantages, that is, it is brittle, not resistant to folding, not wear-resistant, easy to wear and break, and affects the service life. [0005] PTFE microporous film is produced by biaxial stretching technology, has a unique microporous structure, air permeability [0006] Large, low resistance, high particle retention rate, good temperature resistance, resistance to strong acids, alkalis, organic solvents and oxidants, aging resistance and non-stick, non-flammable and non-toxic, biocompatibility and other characteristics, currently PTFE mic...
