Abstract

The invention provides a multifunctional rubber asphalt waterproof material. The multifunctional rubber asphalt waterproof material is prepared by mixing vulcanized rubber modified negative ion emulsified asphalt, rubber latex, an additive 1 and an additive 2, wherein the additive 1 comprises the following components in parts by weight: 0.1-2 parts of silicon dioxide, 0.1-2 parts of diatomite, 0.1-2 parts of a silane coupling agent, 0.1-2 parts of a surfactant, 0.1-1 part of a wetting agent, 0.1-1 part of a dispersing agent and 0.1-2 parts of deionized water. According to the embodiment of the invention, rubber components in the waterproof material are creatively modified by virtue of silicon dioxide, diatomite and the silane coupling agent, so that the physical and mechanical performance of vulcanized rubber for modifying can be improved by virtue of silicon dioxide, diatomite and the silane coupling agent in the additive 1, and the sound insulation performance, noise reduction performance and wear resistance of the vulcanized rubber can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a multifunctional rubber asphalt waterproof material with sound insulation and noise reduction, wear resistance and impact resistance, a preparation method of a multifunctional rubber asphalt waterproof material and a multifunctional rubber asphalt waterproof material. Construction method. Background technique [0002] In recent years, with the continuous expansion of the waterproof market, people have more and more requirements for waterproofing. Especially with the rise of high-speed rail, the waterproof industry has been pushed to a new level. Due to the technical requirements of the high-speed rail itself, its track construction is carried out in the form of ballastless track, which has higher requirements for the waterproof standard of the waterproof layer of the ballastless track bridge deck. The high-speed rail is the country's infrastructure construction, and the proj...
