Problems solved by technology

[0004] Although the above formulation system can meet the basic construction requirements, due to the introduction of a large amount of water into the coating, part of the active ingredients will be lost during the demulsification and dehydration process, resulting in a decline in coating quality
In addition, a large amount of chloride ions or sulfate ions are introduced, which are highly corrosive to concrete and seriously affect the service life of buildings.

preparation example Construction

[0031] The second aspect of the present invention provides a method for preparing the above-mentioned liquid-powder co-spraying environment-friendly polymer waterproof coating, the preparation method comprising:

[0032] Mix emulsified asphalt, water-based latex, water-based tackifying resin, softener, pH regulator, and emulsifier evenly to obtain component A; mix powdered hydraulic inorganic gelling material, coagulant, and thickener evenly to obtain component B Component.

[0033] As a preferred solution, when the liquid-powder co-spraying environment-friendly polymer waterproof coating of the present invention is in use, the liquid material is sprayed with a liquid material spraying machine, and the powder material (component B) is sprayed with a special pneumatic sprayer. Adjust the flow rate or weight of component A and component B, then spray at the same time, mix evenly during the spraying process, and adhere to the base layer.

[0034] The purpose of the present inven...

Abstract

The invention discloses a liquid-powder co-spraying environment-friendly persistent adhesive polymer waterproof coating and a preparation and a use method thereof, the liquid-powder co-spraying environment-friendly persistent adhesive polymer waterproof coating comprises a component A and a component B, the component A is a liquid material, the component B is a powder material, and the mass ratio of the component A to the component B is 100: (5-20). According to the liquid-powder co-spraying environment-friendly persistent adhesive polymer waterproof coating, on the basis of ensuring high-efficiency spraying construction at normal temperature and good film-forming property, due to the addition of a tackifying resin and a softening agent, after a sprayed film is cured, the persistent adhesion of the coating film is more prominent, the coating film can be more tightly attached to a base layer and a waterproof roll, the foaming and hollowing phenomena of the material and the base layer are avoided; the adhesion between the coating film and a modified asphalt waterproof coiled material, particularly a self-adhesive waterproof coiled material is enhanced, and meanwhile, the coating is sprayed on a base layer, can be directly used as a waterproof layer after the sprayed film is dried, and can also be attached to any waterproof coiled material for use.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a liquid-powder co-spraying environment-friendly polymer waterproof coating and its preparation and application method. Background technique [0002] Spray-type polymer waterproof coating is a new type of high-performance waterproof product in my country, which is widely used in building roofs, tunnels, sewage treatment plants and other fields. With the improvement of economic level, people put forward higher requirements for product quality, construction quality and construction efficiency. [0003] Component A of general spray-on sticky polymer coatings is generally emulsified asphalt and water-based latex, and water-based latex is generally a formula system of neoprene latex or styrene-butadiene latex and some other additives. Component B is mainly calcium chloride, sulfate and other salt solutions as demulsification curing agent. [0004] Although the...
