Problems solved by technology

[0005] Secondly, the heating temperature of ordinary non-curing rubber asphalt waterproof coating is as high as 150 ℃ to 200 ℃ during construction, which is easy to burn the construction personnel during construction and cause safety accidents
At the same time, a higher construction temperature requires more energy consumption, and fuel combustion produces more greenhouse gases such as carbon dioxide, which accelerates the occurrence of the greenhouse effect.
[0006] Although the non-curing rubber asphalt waterproof coatings currently on the market have excellent elastic-plastic properties, none of them have high heat resistance (≥90°C), low viscosity (≤5.0dps), low temperature workability (sprayable at 130°C) ) and no smoke during construction, which increases the hidden danger of waterproof layer leakage and restricts the development of waterproof technology

Abstract

The invention provides a non-curable rubber asphalt waterproof coating and a preparation method and a composite waterproof roll material thereof. The non-curable rubber asphalt waterproof coating is prepared from, by mass, 100-160 parts of petroleum asphalt, 1-5 parts of rubber modifier, 0.1-3 parts of viscosity regulator and 0.1-3 parts of a catalyst. The chemical crosslinking reaction of the petroleum asphalt and the rubber modifier is achieved by adding the viscosity regulator and the catalyst in the petroleum asphalt and the rubber modifier of the non-curable rubber asphalt waterproof coating, so that the non-curable rubber asphalt waterproof coating has high heat resistance (greater than or equal to 90 DEG C) and low viscosity (smaller than or equal to 5.0 dps), can be sprayed or scraped at the low temperature (sprayable at the temperature of 130 DEG C) and also has energy saving and consumption reducing properties and other special properties on the basis that the common properties of an elastic-plastic paste body are kept within the service life, the comprehensive performance of the non-curable rubber asphalt waterproof coating is improved, and the service life of the non-curable rubber asphalt waterproof coating is prolonged.

Description

technical field [0001] The invention relates to the technical field of construction engineering waterproof materials, in particular to a non- [0002] Cured rubber asphalt waterproof coating, preparation method thereof, and composite waterproof membrane. Background technique [0003] Waterproof membrane (or sheet) and non-curing rubber asphalt waterproof coating, as a composite waterproof system in the field of building waterproofing engineering, have been greatly applied and promoted in the current domestic and international waterproofing engineering markets. Non-curing rubber asphalt waterproof coatings are quickly recognized and applied by the market because of their high compatibility with modified asphalt waterproof membranes. At the same time, they are favored by many customers because of their excellent elasticity and plasticity and can be constructed without open flame hot melting. [0004] However, with the explosive promotion and application of non-curing rubber a...
