Abstract

The invention discloses a preparation method of low-temperature anti-displacement non-cured rubber asphalt, and belongs to the field of waterproof materials. The method comprises the following steps:adding 100 parts of anhydrous gypsum whiskers and 5-10 parts of a silane coupling agent into an organic solvent, reacting for 2-4 hours, adding 5-8 parts of sodium nitrite, 10-14 parts of hydrochloricacid and 5-10 parts of polyether amine, continuously reacting for 1-2 hours, washing with a saturated weak base solution, and carrying out reduced pressure distillation to obtain modified anhydrous gypsum whiskers; mixing 100 parts of 70 # asphalt, 10-15 parts of liquid polymer rubber and engine oil, shearing and homogenizing, adding 1-5 parts of a surfactant, 4-10 parts of aliphatic dibasic acidester and 4-8 parts of low-temperature-resistant nylon, and continuing shearing and homogenizing to obtain modified asphalt A; and adding 5-10 parts of modified anhydrous gypsum whiskers into 100 parts of modified asphalt A, and mechanically stirring and homogenizing to obtain the non-cured rubber asphalt coating. The non-cured rubber asphalt disclosed by the invention is excellent in low-temperature base slippage stress resistance.

Description

technical field [0001] The invention belongs to the field of waterproof materials, and in particular relates to a preparation method of low-temperature displacement-resistant non-cured rubber asphalt. Background technique [0002] Non-curing rubber asphalt waterproof coating is a new type of waterproof material that is prepared by asphalt, rubber and other special functional components through a certain process. It maintains a viscous paste for a long time in the application state and never cures. It has good creep properties. , self-healing and grass-roots adaptability. Since entering the Chinese market in 2007, it has attracted the attention of many researchers. [0003] Uncured asphalt can be used alone as a waterproof sealing layer, or it can be used in combination with other waterproof membranes. In recent years, especially with the popularization of "composite waterproof layer" technology, non-cured asphalt has been rapidly promoted and applied as the coating waterpr...
