Thermal insulation mortar using rubber powder of waste tire

Abstract

The invention aims to provide a thermal insulation mortar using large amount of waste tire, comprising tire rubber, cement, emulsion powder, fiber and cellulose ether and the like; the main proportionof cement to emulsion powder to tire rubber is 1:0.2:0.6; the particle size of tire rubber particle is in the range of 0.1-5 mm; thus, high flexible thermal insulation mortar of rubber powder is doped; by researching and testing the performances of flexible mortar, the intensity of mortar can be reduced by rubber powder to improve compression strength of mortar, thereby increasing resistance to deformation of the thermal insulation mortar, and improving the anti-cracking performance of the thermal insulation mortar. The invention has the characteristics of fine chemical resistance, no water absorption, great toughness, fine anti-cracking performance and fine thermal insulation performance, and is used for preparing thermal insulation mortar, thereby not only showing thermal insulation andenergy saving of buildings, but also having fine environmental effect.

Description

technical field [0001] The present invention relates to a kind of mortar, especially thermal insulation mortar. Background technique [0002] At the beginning of the 21st century, my country's automobile industry developed rapidly, and the number of residents' automobile ownership continued to increase. According to statistics, the United States currently has 700 cars per 1,000 people, while my country only has 24 cars per 1,000 people. Therefore, it can be asserted that my country's auto industry is just in its infancy, and there is still huge room for development. However, we have also seen that a large number of waste tires are also increasing. In 2006, there were more than 100 million pieces. It is conceivable that the subsequent data are so huge. According to incomplete statistics, there are about 20% of them at present. More waste tires have not been properly recycled and utilized. A large part of these tires are piled up together, which not only seriously pollutes o...

[0004] These recycling methods still cannot make full use of all the waste tires in our country. In view of the fact that the waste tires will increase exponentially, we should actively improve the existing recycling methods and develop new recycling methods to recycle them as completely as possible. waste tire
