Problems solved by technology

However, due to the poor performance of asphalt in terms of high temperature resistance, fluidity resistance, low temperature flexibility and weather resistance, there are many problems in the application effect of the waterproof membrane produced by it: such as poor low temperature flexibility, low temperature waterproof roll The material is very brittle and easy to break; it is not resistant to high temperature, the coil material will flow and drip at high temperature, and it is difficult to tear the film; and the cohesion is not ideal, resulting in easy separation from the base surface, etc.
[0003] Therefore, research and development of an asphalt rubber material suitable for waterproof membranes with strong low temperature flexibility, high temperature resistance and strong cohesive force can alleviate the poor low temperature flexibility, low temperature resistance, and weak cohesive force of existing asphalt waterproof membranes. Issues such as fundamentals have become very necessary and urgent

Abstract

The invention provides an asphalt sizing material for a waterproof coiled material, a preparation method of the asphalt sizing material, and the waterproof coiled material, and relates to the technical field of the waterproof coiled material. The asphalt sizing material is mainly prepared from asphalt, butadiene styrene rubber, petroleum resin, polypropylene wax, erucyl amide, a softening agent and a stabilizer, wherein the butadiene styrene rubber can obviously improve the low-temperature flexibility and the high-temperature resistance of the asphalt sizing material; the petroleum resin can obviously improve the viscosity, the hardness and the heat stability of the asphalt sizing material; the polypropylene wax and the erucyl amide can obviously improve the high-temperature resistance and the heat stability of the asphalt sizing material; the softening agent can effectively improve the viscosity and the ductility of the sizing material; and the stabilizer can prevent decomposition and ageing of the sizing material. Therefore, the asphalt sizing material provided by the invention can obviously improve the low-temperature flexibility, the high-temperature resistance and the cohesive force through compounding of the components and the component content, and has excellent waterproof property. The asphalt sizing material can be widely applied to preparation of various types of waterproof coiled materials.

Description

technical field [0001] The invention relates to the technical field of waterproof membranes, in particular to an asphalt rubber material used for waterproof membranes, a preparation method thereof, and waterproof membranes. Background technique [0002] Bitumen is a product of crude oil processing, which is a black or dark brown viscous liquid or solid at room temperature. The main components of asphalt are asphaltenes and resins, followed by high-boiling mineral oil and a small amount of oxygen, sulfur and chlorine compounds. Asphalt is brittle at low temperature, but its cohesiveness, waterproof performance and anti-corrosion performance are very good, and it has been widely used in the fields of road, waterproof engineering and anti-corrosion. However, due to the poor performance of asphalt in terms of high temperature resistance, fluidity resistance, low temperature flexibility and weather resistance, there are many problems in the application effect of the waterproof m...
