At present, the formation of polyvinyl chloride coating on glass fiber fabrics generally adopts the method of smearing, that is, coating molten polyvinyl chloride on glass fiber fabrics. Since polyvinyl chloride has a high viscosity in a molten state, polyvinyl chloride It can only be bonded to the surface of the glass fiber fabric, which leads to the PVC coating being easy to fall off after a long time of use, and the direct cooling method is adopted in the cooling process of the PVC, that is, the colder The air is connected to polyvinyl chloride to cool down, causing the outer layer of polyvinyl chloride to solidify instantly, but the inner layer is not solidified, and there is a difference in solidification time between the inner and outer layers, which reduces the quality of polyvinyl chloride and leads to a lower service life

Embodiment Construction
[0026] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0027] Such as figure 1 Shown, the preparation method of coating polyvinyl chloride resin on the glass fiber fabric surface may further comprise the steps:
[0028] a. Cloth delivery: Pull out the glass fiber fabric that is wound into a tube, and tighten the glass fiber fabric in the warp and weft directions during the pulling process;
[0029] b. Dust removal: Remove the dust that may exist on the glass fiber fabric through the dust blowing device after the stretched glass fiber fabric;
[0030] c. Preheating: preheat the glass fiber fabric through an oven, and the preheating temperature is 70°C to 80°C;
[0031] d. Spraying material: pass the preheated glass fiber fabric under the nozzle, the nozzle is connected to the...

Abstract
The invention provides a manufacturing method of coating polyvinyl chloride resin on surface of glass fiber fabrics and belongs to the technical field of coating. The manufacturing method solves the technical problem that the service life of the conventional glass fiber fabrics with a polyvinyl chloride coating is low. The manufacturing method of coating polyvinyl chloride resin on surface of glass fiber fabrics includes the steps of, a, pulling clothes; b, removing dust; c, preheating; d, spraying; e, pressing; f, cooling; and g, collecting clothes. The manufacturing method has the advantages of forming the polyvinyl chloride resin on the surface of glass fiber fabrics and improving the service life.
Description
technical field [0001] The invention belongs to the technical field of composite materials, and relates to a preparation method for coating polyvinyl chloride resin on the surface of glass fiber fabrics. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. It has excellent properties such as non-combustibility, high temperature resistance, electrical insulation, high tensile strength, and good chemical stability. People use these characteristics of glass fiber to make it into fabrics. Hope Fabrics are able to maintain these characteristics, however, since fiberglass is not abrasion resistant, a protective layer needs to be reapplied. At present, polymer coatings are generally used to achieve this goal. This coating must retain the original strength of the glass fiber to the greatest extent, and avoid mechanical and thermodynamic defects as much as possible at the joint between the coating and the glass fiber. After the ...
