Problems solved by technology

[0002] At present, polymer cement-based waterproof materials still have poor water resistance and short service life, so they cannot be used for second-level and above waterproof roofs and important waterproof projects.
When acrylate polymer emulsion is used as the liquid material of polymer cement waterproof coating, there are disadvantages such as poor water resistance, which affects the waterproof function of polymer waterproof coating

Abstract

The invention relates to an asphalt polymer cement waterproof coating which consists of a component A and a component B. The component A comprises the raw materials in percentage by weight as follows: 20-50% of emulsified asphalt, 30-50% of modified latex and 10-30% of water. The component B comprises the raw materials in percentage by weight as follows: 40-60% of cement, 20-40% of staffing and 1-5% of assistant. The coating provided by the invention is low in price, good in waterproofness and good in flexibility, and can resist corrosion caused by low concentration inorganic acid, base and salt. The asphalt polymer cement waterproof coating can be independently used as a film waterproof layer in waterproof and corrosion resisting projects of kitchens and bath rooms, basements and bridge floors.

Description

technical field [0001] The invention relates to an asphalt-based waterproof coating, which is mainly used for coatings in the field of waterproof and anticorrosion, in particular to an asphalt polymer cement waterproof coating. technical background [0002] At present, polymer cement-based waterproof materials still have poor water resistance and short service life, and cannot be used for second-level and above waterproof roofs and important waterproof projects. When the acrylate polymer emulsion is used as the liquid material of the polymer cement waterproof coating, there are disadvantages such as poor water resistance, which affects the waterproof function of the polymer waterproof coating. Asphalt has the advantages of wide source of materials, low price, low-concentration inorganic acid, alkali and salt corrosion, and it is waterproof and self-healing to a certain extent. Contents of the invention [0003] This product is an anti-leakage and anti-corrosion bituminous...
