Problems solved by technology

[0004] The problem to be solved by the present invention is to solve the problem that the construction temperature of the current non-curing rubber asphalt waterproof material is too high, and the method of low-viscosity basic formula + thixotropic system thickening + viscosifying system is adopted to improve the low temperature of the formula At the same time, the high temperature resistance effect of the formula is improved by adding a compound thixotropic system, which can reduce the spraying or scraping construction temperature of the waterproof material to 70-80°C, and the high temperature resistance effect can reach above 60°C, which is extremely Greatly improved the construction convenience and construction safety of the formula

Abstract

The invention provides non-cured rubber asphalt waterproof coating capable of being sprayed at low temperature. The formula of the coating comprises the following components in parts by mass: 160-200parts of petroleum asphalt, 5-10 parts of a No.1 rubber modifier, 8-20 parts of a No. 2 rubber modifier, 4-5 parts of an adhesion promoter, 1-2 parts of an antioxidant, 1-2 parts of an ultraviolet absorber, 20-40 parts of a filler, 2-4 parts of a dispersant, 10-20 parts of a composite thixotropic regulator. The composite thixotropic regulator is prepared by heating, mixing and activating 15 to 25parts by mass of hydrophobic modified polyamide wax, 5 to 10 parts by mass of bentonite 1, 15 to 20 parts by mass of bentonite 2 and 100 parts by mass of hydrogenated castor oil. According to the prepared coating, the construction spraying temperature can be greatly reduced; compared with the spraying construction temperature of 130 DEG C or above of common non-cured waterproof coating, the spraying construction temperature of the formula product can be reduced to 70-80 DEG C, the heating temperature and energy consumption during construction can be greatly reduced, and potential safety hazards during construction can be effectively avoided.

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...
