Abstract

The invention provides waterproof asphalt which comprises the following components in parts by weight: 40-70 parts of No.70 asphalt; and 40 to 70 parts of base oil. The No.70 asphalt is residual oil obtained by distilling blended crude oil; the base oil comprises second line vacuum distillation wax oil; third line vacuum distillation wax oil; and coker gas oil. the second line vacuum distillation wax oil and the third line vacuum distillation wax oil are side fractions obtained by reduced pressure distillation of blended crude oil; and the blended crude oil comprises the crude oil and the coker gas oil. According to the waterproof asphalt provided by the invention, a crude oil blending method and a base oil compounding method are mutually coordinated and matched, so that the defects of waterproof asphalt raw materials and base oil in the traditional sense are overcome, and the technical difficulties that W200 # waterproof asphalt is unstable in performance index and high and low temperature performance conflicts are solved; and the technical problems of low-temperature performance, stripping performance, heat resistance and the like of the self-adhesive waterproof coiled material based on the W200 waterproof asphalt are effectively improved. The invention further provides a waterproof roll.

Description

technical field [0001] The invention belongs to the technical field of bitumen, and in particular relates to a waterproof bitumen and a waterproof coiled material. Background technique [0002] Asphalt-based self-adhesive membranes use modifiers, asphalt, and softening oil as raw materials. They have the advantages of strong adhesion, good self-healing properties, excellent elongation performance, and stable high and low temperature performance. They have been popularized and applied in the construction waterproof industry. Rapid development. So far, it is still one of the important membrane products in the field of waterproof materials. With the expansion of the business of waterproofing enterprises, the demand for asphalt-based self-adhesive membranes is increasing. Therefore, as the main raw material of self-adhesive membrane, W200 waterproof asphalt is in increasing demand, and the market has higher and higher requirements for the stability of W200 waterproof asphalt p...
