Problems solved by technology

Polypropylene (PP) material has the advantages of light weight, non-toxic, odorless, moisture-proof, high mechanical strength, good dimensional stability, good printing performance, good transparency, etc., making it a better material than paper and polyvinyl chloride (PVC). It is a popular packaging material, but polypropylene has a high shrinkage rate and is easy to burn. The product is easily aged by light, heat and oxygen during use.
Pure PVC film or pure PP film cannot meet the requirements of high strength, high fire resistance and / or high durability in some industries in modern industry

Abstract

The invention provides a high strength refractory and durable film characterized by high strength, good fire resistance and good durability. The high strength refractory and durable film includes a composite glass fiber layer and a coating layer, a refractory reinforcing layer, a fireproof film layer and a PET film layer that are disposed on both sides of the composite glass fiber layer from the inside out in order. The composite glass fiber layer is formed by interlacing of glass fiber composite yarns, the coating layer is a modified polypropylene resin coating layer, the refractory reinforcing layer is chopped glass fiber jetted on the coating layer, the fireproof film layer is a fireproof emulsion coating material coated on the surface of the refractory reinforcing layer, and the PET film layer is a high strength polyester film. The high strength refractory and durable film provided by the invention adopts the composite glass fiber layer as the center layer, so that the film can have good core strength, the chopped glass fiber and fireproof emulsion cooperated thermal insulation and flame retardancy are utilized to enhance the fire retardancy of the whole film, and the surface is provided with the high strength polyester film layer, so that the film can have high durability.

Description

technical field [0001] The invention relates to a film, in particular to a high-strength fire-resistant and durable film. Background technique [0002] Polyvinyl chloride (PVC) material has the advantages of short manufacturing cycle, low energy consumption, low cost, light weight, high tensile strength, corrosion resistance, and good waterproof performance, so it is widely used in building materials, industrial products, daily necessities, Floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. The top layer of traditional PVC film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material widely used in the world today. PVC film has the characteristics of rainproof, fire resistance, antistatic, and easy to form. Its hardness is higher than that of low-density polyethylene, but lower than that of po...
