Problems solved by technology

Due to the rapid development of the construction industry, the demand for waterproof materials is increasing. Asphalt waterproof membranes have made some research progress as the main waterproof material. However, ordinary waterproof membranes generally have poor extensibility and are easy to crack during construction. Although the waterproof membrane can improve its elongation performance to a certain extent, the formula is relatively simple, and the filler is mostly calcium carbonate with a single component. The adhesiveness of the membrane is not good, and the elongation and fracture resistance are not high; The waterproof membrane does not have the function of plant root puncture, so it cannot be used in the construction of building roofs; in addition, as the price of the monomer of the SBS material continues to increase, the cost of the SBS modified bitumen waterproof membrane has also been greatly increased, which seriously restricts its development

Abstract

The invention provides a modified-asphalt-modified waterproof material and a preparation method thereof. The modified-asphalt-modified waterproof material is prepared from asphalt, ABS (acrylonitrile-butadiene-styrene) high rubber powder, a maleic resin, a polybenzofuran resin, vinyl silicone oil, naphthenic oil, n-butyllithium, diallyl phthalate, a p-tert-octyl phenol formaldehyde resin, polyisobutylene, coal gangue, vermiculite, diabase, azobisformamide, octadecylamine, carboxyl betaine, vinyl bis stearamide, allyl polyethyleneglycol and allyl alcohol polyoxy alkyl ether. The asphalt-base waterproof material is not modified by SBS (styrene-butadiene-styrene), so the manufacturing cost is lower. The waterproof material has the advantages of excellent water resistance and high bonding firmness and durability with the substrate. Besides, the asphalt-base waterproof material has favorable extensibility, the elongation percentage at the maximum pull is not less than 48%, and the asphalt-base waterproof material can resist the low temperature of -25 DEG C without cracking and has excellent comprehensive properties and favorable market competitiveness.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and in particular relates to a modified asphalt-based waterproof material and a preparation method thereof. Background technique [0002] In waterproofing projects, asphalt is the most widely used waterproof material in waterproofing and anti-seepage projects at home and abroad because of its advantages such as easy availability of raw materials and low price. Due to the rapid development of the construction industry, the demand for waterproof materials is increasing. Asphalt waterproof membranes have made some research progress as the main waterproof material. However, ordinary waterproof membranes generally have poor extensibility and are easy to crack during construction. Although the waterproof membrane can improve its elongation performance to a certain extent, the formula is relatively simple, and the filler is mostly calcium carbonate with a single component. The adhesiveness ...
