A kind of rubber asphalt stabilizer and preparation method thereof

Abstract

The invention provides a rubber asphalt stabilizer and a preparation method thereof. The rubber asphalt stabilizer is prepared from 15 to 20 percent of stearoylbenzoylmethane, 20 to 30 percent of lanthanum sodium sulfhydryl acetate, 8 to 12 percent of cerium stearate, 2 to 4 percent of hydrotalcite powder, 2 to 4 percent of white mica powder, 20 to 25 percent of tetra n-butyl titanate and 17.5 to 20 percent of a plasticizer, wherein the total weight percentage of the raw materials is 100 percent. The preparation method comprises the following steps: mixing the hydrotalcite powder, the white mica powder and the tetra n-butyl titanate to prepare a mixture A; mixing the cerium stearate, the stearoylbenzoylmethane and the lanthanum sodium sulfhydryl acetate to prepare a mixture B; mixing the plasticizer, the mixture A and the mixture B to prepare a mixture C, cooling the mixture C to a room temperature, and carrying granulation molding. The rubber asphalt stabilizer disclosed by the invention is applicable to rubber asphalt made from waste tires and overcomes the shortcoming that the common rubber asphalt needs to be freshly made and cannot be transported and stored, so that the rubber asphalt has higher use value, can effectively solve the environmental problem caused by the waste tires and has outstanding social and economical benefits.

Description

technical field [0001] The invention belongs to the field of road engineering, and relates to a rubber asphalt admixture, a rubber asphalt stabilizer and a preparation method thereof. Background technique [0002] Due to the rapid development of my country's economy, people's living conditions have been greatly improved, and the number of domestic vehicles has increased year by year, resulting in an explosive growth in the storage of waste tires, which has caused tremendous pressure on the environment. Effective disposal of waste tires has become a top priority for our country. [0003] Process waste tires into rubber powder, combine them into asphalt according to a certain ratio of thickness and fineness, and fully mix them under certain conditions to make rubber asphalt. The advantages of rubber asphalt are as follows: 1) It can effectively deal with a large number of discarded tires, relieve environmental pressure, and achieve the purpose of resource reuse. 2) The produc...
