Problems solved by technology

However, since the flame retardant used in the formula of the film layer cannot produce a special chemical structure with other substances in the film layer, when the PVC film structure material encounters tearing or peeling problems after long-term use, its resistance Combustibility, washing resistance, and durability will decrease

Abstract

The invention relates to a tear-resistant, peel-resistant and flame-retardant PVC membrane structural material preparation method and a product, wherein the preparation method includes the steps: mixing and stirring 100 parts of polyvinyl chloride resin, 55-65 parts of diisononyl ortho-phthalate, 5-25 parts of a modified flame-retardant smoke suppressant, 1-5 parts of isophorone diisocyanate, 1-5parts of a barium-zinc thermal stabilizer, 1-5 parts of fatty alcohol-polyoxyethylene ether, and 5-20 parts of a diluent, to obtain a PVC impregnating solution; immersing a polyester fabric in the PVCimpregnating solution, extruding by a rolling drum, drying, and cooling, to obtain a modified polyester fabric; preheating the modified polyester fabric under a condition of the temperature of 90-125DEG C; preheating a 0.1-0.5 mm thick PVC film under a condition of the temperature of 150-205 DEG C, then carrying out hot pressing with the modified polyester fabric, and cooling to obtain the tear-resistant, peel-resistant and flame-retardant PVC membrane structural material. The method modifies the PVC impregnating solution and the flame-retardant smoke suppressant in the PVC impregnating solution, so that the product has more superior tear resistance and peeling resistance, and further improves flame retardant stability, water scrubbing resistance and durability.

Description

technical field [0001] The invention relates to the field of preparation of PVC film structural materials, in particular to a preparation method and product of a tear-resistant, peel-resistant, flame-retardant PVC film structural material. Background technique [0002] The membrane structure material is composed of base cloth and coating. The base cloth is mainly made of polyester fiber and glass fiber, and the coating material is mainly polyvinyl chloride and polytetrafluoroethylene. [0003] Common membrane materials are polyester fiber-polyvinyl chloride (PVC) and glass fiber-polytetrafluoroethylene (Teflon). The main characteristics of PVC material are low strength, high elasticity, easy aging, large creep, and poor self-cleaning property, but it is cheap, easy to process and produce, rich in color, and has good folding resistance. In order to improve its performance, a layer of polytetrafluoroethylene coating can be coated on its surface to improve its anti-aging and s...
