Problems solved by technology

According to estimates, the production and construction process of every 1,000 tons of non-curing rubber asphalt waterproof coating consumes energy equivalent to 200,000Kg of standard coal, and additionally emits 135,000Kg of dust pollution and 38,000Kg of carbon dioxide, causing huge damage to energy consumption and the environment. pressure
[0006] (2) The harm of organic matter to the environment and personnel during the production and use of non-curing rubber asphalt waterproof coatings
[0008] (3) The production and construction process is complex and the equipment is expensive
In the technical solutions of the above three patents, the raw materials need to be heated at a high temperature of 100-200°C in the production process of the product, which consumes a lot of energy; moreover, the raw materials of the product contain highly polluting and highly toxic substances such as asphalt or isocyanate, which cannot meet the requirements. Use in occasions with high environmental requirements

Abstract

The invention discloses a water-based non-asphalt-based non-curing waterproof coating and a preparation method thereof. The coating is characterized by comprising, by mass, 0-200 parts of water, 50-300 parts of a base emulsion, 5-150 parts of a plasticizer, 0-300 parts of a tackifying emulsion, 10-500 parts of a modified emulsion, 0-20 parts of a thickening agent, 0-8 parts of a dispersing agent,0-250 parts of a filler, 0-15 parts of a nano modifier, 0.5-1 part of a mildew inhibitor and 0.5-3 parts of a preservative. The water-based non-asphalt-based non-curing waterproof coating has the advantages of being environmentally friendly, low in energy consumption, capable of facilitating production and construction and the like.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a water-based non-asphalt-based non-curing waterproof coating and a preparation method thereof. Background technique [0002] In recent years, non-curing waterproof coating technology has developed rapidly, and construction applications have become increasingly widespread. Non-curing waterproof coating is a non-film-forming, non-curing creep-type waterproof coating, and its coating remains viscous throughout its effective service life. Since this waterproof coating does not form a coating film, even if the base layer is deformed, the coating will not be affected by stress transmission, and can always maintain adhesion to the base layer. The interface develops adhesion. At the same time, because the non-curing waterproof coating does not need to form a film, it does not need maintenance. After construction, the construction of the next process can be carried out dir...
