Abstract

The invention provides a non-curing rubber asphalt waterproof coating capable of spraying at low temperature, the formula includes 160-200 parts by mass of petroleum asphalt; 5-10 parts by mass of No. 1 rubber modifier; 8-20 parts by mass of No. 2 rubber modifier 4-5 parts by mass of adhesion promoter; 1-2 parts by mass of antioxidant; 1-2 parts by mass of ultraviolet absorber; 20-40 parts by mass of filler; 2-4 parts by mass of dispersant, composite thixotropic adjustment 10-20 parts by mass of agent, wherein the composite thixotropic regulator is hydrogenated by the hydrophobic modified polyamide wax of 15-25 parts by mass, the bentonite 1 of 5-10 parts by mass, the bentonite 2 of 15-20 parts by mass, and the hydrogenation of 100 parts Castor oil is prepared by heating, mixing and activating. The low-temperature sprayable non-curing rubber asphalt waterproof coating prepared by the present invention can greatly reduce the construction spraying temperature. Compared with the spraying construction temperature of the common non-curing waterproof coating above 130°C, the spraying construction temperature of the formula product can be reduced. To 70-80 ℃, can greatly reduce the heating temperature and energy consumption during construction, and can effectively avoid safety hazards during construction.

Description

technical field [0001] The invention relates to a non-curing rubber asphalt waterproof paint which can be sprayed at low temperature, and belongs to the field of waterproof paint manufacture. [0002] technical background [0003] Non-curing rubber asphalt waterproof coating, as part of a common composite waterproof system used in conjunction with SBS modified asphalt waterproofing membranes, has broad application prospects in the current domestic waterproof material market and is widely used in modified asphalt. In the composite waterproof system of coil bonding, due to the high adhesiveness and non-curing technical design of the material itself, it generally needs to be heated to above 150°C for scraping or spraying during construction, which not only greatly reduces the convenience of construction Moreover, the use of high temperature heating construction will also cause environmental and safety hazards. Therefore, reducing the construction temperature of non-curing rubber...
