Abstract

The invention provides a waterproof material and a method for preparing a waterproof coiled material by using the waterproof material, and relates to an adhesive material based on an asphalt material and an application thereof. The waterproof material provided by the invention is low in cost of raw materials, easy in obtaining of the raw materials, simple to operate and pollution-free and has strong primary viscidity and durability. The preparation method of the waterproof coiled material comprises the following steps: adding thermoplastic SBS (Styrene Butadiene Styrene) rubber 1401, active rubber powder, basic rubber oil, resin, a coupling agent and a surface active agent to asphalt No.90, heating and stirring; grinding, and uniformly mixing; and cooling, adding silicate mineral powder, stirring and cooling. The waterproof material and the waterproof coiled material are low in cost of the raw materials; the prepared product has permeability resistance, self-healing capacity, permanent adhesive strength, excellent shock resistance, puncture resistance, excellent elasticity, excellent tensile property and excellent low temperature property and is safe, environment-friendly and energy-saving in a using process. The waterproof coiled material is used in the field of building waterproofing.

Description

technical field [0001] The present invention relates to a binder material based on bituminous material and its use. Background technique [0002] The original waterproofing membranes were tar pitch and petroleum pitch paper-backed felt. Originated in Europe, it was introduced into my country in the 1920s. With the advancement of science and technology, modern waterproof materials have developed rapidly. By the 1970s, my country's waterproof materials had gradually formed a trend, and new products were being developed to meet market demand. [0003] The main object of building waterproofing is concrete. During the hydration process of cement, excess water other than hydration is released. The shrinkage and creep of concrete will cause some tiny capillary pores or visible small holes to be formed in concrete. As the saying goes, water is pervasive, and water leakage is inevitable. Therefore, the core of waterproofing is to find a way to seal and block capillary pores, and st...
