Preparation method of SBS modified asphalt energy-saving thermal-insulation waterproof coiled material

Abstract

The invention provides a preparation method of an SBS modified asphalt energy-saving thermal-insulation waterproof coiled material, and relates to the technical field of preparation of energy-saving thermal-insulation waterproof coiled materials. The SBS modified asphalt energy-saving thermal-insulation waterproof coiled material comprises a first SBS modified asphalt layer and a second SBS modified asphalt layer which coat the upper surface and the lower surface of a framework layer, a high-temperature-resistant fireproof layer is bonded to the upper surface of the first SBS modified asphaltlayer, and a surface SBS modified asphalt layer is arranged on the upper surface of the high-temperature-resistant fireproof layer; an upper surface isolating membrane layer and a lower surface isolating membrane layer are respectively arranged on the outer surfaces of the surface SBS modified asphalt layer and the second SBS modified asphalt layer; and the framework layer is formed by compoundingand processing thin steel wires and a polyester base. By designing the three SBS modified asphalt layers, the waterproof performance of the thermal-insulation waterproof coiled material can be greatly improved, the high-temperature-resistant fireproof layer is arranged between the two SBS modified asphalt layers, the high-temperature-resistant and sun-proof performance of the thermal-insulation waterproof coiled material can be greatly improved, and the thermal-insulation waterproof coiled material is worthy of vigorous popularization.

Description

technical field [0001] The invention relates to the technical field of preparation of energy-saving, heat-preserving and waterproof coils, in particular to a method for preparing SBS modified asphalt energy-saving, heat-preserving and waterproof coils. Background technique [0002] Waterproof membrane, a rolled waterproof material made of asphalt, rubber or other organic materials, commonly known as linoleum or linoleum, it has good waterproof and good flexibility, impregnated with asphalt or polymer waterproof material in the tire In general, the waterproof material products made are provided in the form of coils, called waterproof coils, which are divided into asphalt waterproof coils, polymer modified bitumen waterproof coils and synthetic polymer waterproof coils according to the main composition materials. According to the different carcass, it can be divided into carcassless coil, paper tire coil, glass fiber tire coil, glass cloth tire coil and polyethylene tire coil....

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a method for preparing SBS modified asphalt energy-saving, heat-preserving and waterproof coiled material, which solves the problems of existing waterproof coils on the market There are certain defects in the design of the material structure. Although its overall waterproof performance is relatively good, when it is laid on the roof of an open-air building, its overall waterproof performance will be greatly reduced after years of high temperature, sun, wind and rain. Problems affecting subsequent use
