Problems solved by technology

The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive; its material is relatively light, waterproof, moisture-proof, flame-retardant and heat-insulating; It is easy to deform when working in a hot environment, and it is easy to deform after being used for a long time, and it is generally toxic. For example, the toxicity of PVC plastic wrap comes from ethylhexylamine (DEHA) plasticizer; non-toxic PVC materials need to add special p

Abstract

The invention provides a TPU mesh fabric, which is made by coating a special PU adhesive to a high-strength polyester fiber and then combining with a TPU film. The PU coating steps are: PU-coat arrow dry arrow cool the high-strength polyester fiber; the coating quantity is 180-200g/m2; the coating speed is 20-25m/min; the drying temperature is 110-130 DEG C; the two layers of TPU film (underlayer, face layer) are preheated and fused through the adjustment and change of the heating drum temperature, and then are rolled, cooled and formed with the high-strength polyester mesh fabric after middle-layer preheating through rubber roller and iron roll. The TPU mesh fabric has the advantages of environmental protection, innocuity, high strength, abrasion resistance, high cold tolerance, good color stability, good heat resistance and best PVC-replacing material.

Description

technical field [0001] The invention belongs to the field of chemical industry, and more specifically relates to a TPU sandwich net. Background technique [0002] PVC materials are widely used in modern life, such as various building materials, household items, etc., the full name is Polyvinylchlorid, the main ingredient is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive; its material is relatively light, waterproof, moisture-proof, flame-retardant and heat-insulating; It is easy to deform when working in a hot environment, and it is easy to deform after being used for a long time, and it is generally toxic. For example, the toxicity of PVC plastic wrap comes from ethylhexylamine (DEHA) plasticizer; non-toxic PVC materials need to add special plasticizers. Plastic, its...
