Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of building materials, in particular to a self-leveling light sound insulation mortar prepared by utilizing waste rubber.
[ background of the invention ]
The waste rubber belongs to thermosetting polymer plastics, is difficult to degrade under natural conditions, and cannot be decomposed and degraded if being abandoned on the ground or buried underground for more than ten years. According to statistics, the amount of waste tires in China is large, and the number of the waste tires is as large as 5000 or more ten thousands, and the amount of the waste tires to be treated accounts for about 1.4 percent of the total amount. The environmental protection pressure is getting bigger and bigger due to the black pollution formed by the waste tires. Therefore, recycling of waste rubber is also receiving more attention. Meanwhile, with the rapid development of modern science and technology and the continuous improvement of the living standard of social materials, noise pollution becomes a worldwide problem. Among them, disputes caused by poor solid impact sound insulation on the building floor are generated in large quantity, and the problem of impact sound insulation between floors becomes a problem to be solved urgently.
At present, relevant researches and patents for preparing sound insulation mortar by using waste rubber exist. Related researches are carried out like Ji university and Chongqing university, but the researches mostly focus on sound insulation mortar in a common flow state, and the researches on sound insulation mortar with high fluidity and self-leveling property are less. The hydrophobic property of the rubber particles makes the rubber particles have poor fusion with a cement paste system, the particles are easy to float upwards in a layered mode and disperse unevenly, and the influence is larger particularly on the preparation of large-flow-state mortar. Meanwhile, the elastic body of the rubber particles can easily become a weak link in the whole mortar system, so that the strength of the product is reduced. The special mortar with high flow state, high strength and low impact sound pressure level is prepared by particle modification and formula optimization.
