Asphalt material for high-toughness and tear-resistant waste rubber powder modified waterproof coils and preparation method thereof

Abstract

The invention discloses an asphalt material for high-toughness and tear-resistant waste rubber powder modified waterproof coils. The asphalt material is prepared from the following raw materials in parts by weight: 40 to 60 parts of asphalt, 5 to 10 parts of gypsum whisker, 10 to 15 parts of 100 to 200-mesh waste tire rubber powder, 5 to 10 parts of neoprene latex with solid content of 30 to 40%, 3 to 5 parts of linear phenolic resin, 1 to 1.5 parts of polysorbate 80, 0.3 to 0.5 part of polyethylene wax, 0.5 to 1 part of calcium chloride water solution with mass concentration of 0.5 to 1%, and 4 to 8 parts of cashew nut shell oil. The asphalt material for the rubber powder modified waterproof coils has the characteristics that the uniformity and stability are high; the durability is good, the toughness is high, the tear-resistant property is good, the cost is low, the service life is long, and the economic and practical effects are realized.

Description

technical field [0001] The invention relates to the technical field of modified asphalt, in particular to a high-toughness and tear-resistant waste rubber powder modified asphalt material for waterproof coiled materials and a preparation method thereof. Background technique [0002] As a by-product of petroleum processing, asphalt has become the main paving material and waterproof material in highways, airports, construction and other fields at this stage. The application in construction is more and more favored by people, especially in the construction of the roof of the building, the sky of the subway and the top of the dam culvert. The side of the modified asphalt coil with the adhesive is directly pasted on the concrete surface to achieve waterproofing. the goal of. At the same time, with the increasing production of waste tires in our country, the disposal of a large number of waste tires has brought us a severe test. Due to the environmental protection of reclaimed ru...

Problems solved by technology

[0003] Since the waste rubber powder is made by chemical or mechanical processing, its surface is composed of the network ends of the destroyed space network, and its surface is irregular and burr-like and full of onlooker cracks, so the rubber powder modified asphalt material During the processing, there is no uniform system between the rubber powder and the asphalt, and the structure is relatively loose, which is prone to cracking and affects the durability of the material.
