Abstract

The invention relates to an efficient and environment-friendly rubber-powder-modified asphalt waterproof coiled material and a preparing method. The preparing method comprises the steps of mixing anduniformly stirring 34-54 parts of matrix asphalt and 1.5-15 parts of softening oil, increasing the temperature to 150-170 DEG C, starting to add 10-15 parts of waste rubber powder and 0.01-0.03 part of an activating agent, increasing the temperature, maintaining the temperature at 170-180 DEG C, conducting development for 60-80 minutes at the rotation speed of 20-200 r / min, afterwards, adding 4-15parts of waste rubber powder, conducting stirring development for 10-20 minutes, conducting cutting and grinding once through a colloid mill, adding 15-30 parts of a filler, and then conducting stirring development for 30-60 minutes to obtain a modified asphalt coating material; conducting coating and cladding technologies on the prepared modified asphalt coating material, and then conducting cooling rolling to prepare the rubber-powder-modified asphalt waterproof coiled material. According to the efficient and environment-friendly rubber-powder-modified asphalt waterproof coiled material andthe preparing method, by adding the activating agent, all technology parameters of the batching period are greatly adjusted, the technology time can be shortened, the technology temperature and stirring speed can be lowered, and the prepared product also has better performance indexes, has excellent storage stability and application performance, and is an efficient, energy-saving and environment-friendly product.

Description

technical field [0001] The invention relates to a rubber powder modified bitumen waterproof coiled material and a preparation method thereof, belonging to the technical field of waterproof coiled materials. Background technique [0002] With the development of society, people's awareness of prevention is getting higher and higher, and they are paying more and more attention to the waterproof effect of residences, infrastructure, public facilities, etc. Subsequently, the requirements for the performance of waterproof materials are getting higher and higher. At present, the main waterproof materials on the market include asphalt waterproofing membrane, waterproof coating, and polymer waterproofing materials, while asphalt waterproofing membrane accounts for more than 60%, still occupying most of the market share. However, asphalt, as the main material of the asphalt waterproofing membrane, has the problems of high-temperature flow and low-temperature brittleness. Waterproofin...
