Problems solved by technology

[0005] Chinese Patent Publication No. CN106398519A discloses a high-permeability waterproof coating and its preparation method and application, so as to alleviate the technical problems of existing coatings with poor water resistance and permeability resistance
The hydrophobic coating of this invention endows the product with better water resistance due to the addition of fullerene, but the price of fullerene is extremely expensive, and this product has no penetration function, nor does it have an anti-corrosion function for the steel structure inside the concrete, and mainly forms a film The substance is acrylic emulsion, which will become soft and sticky in the environment of long-term water immersion, which will affect its waterproof effect

Abstract

The invention relates to a permeable hydrophobic multifunctional novel waterproof coating and a preparation method and applications thereof. The permeable hydrophobic multifunctional novel waterproofcoating contains the following components in parts by weight: 30-45 parts of film-forming substances, 4-8 parts of permeable waterproof hydrophobic material, 0.3-0.6 parts of auxiliaries, 0.5-2 partsof osmotic corrosion inhibitor, appropriate amount of pigment, 1-6 parts of thickener, 1-12 parts of reactive diluent, 3-6 parts of flexibilizer, and 30-45 parts of padding, and the use amount of spiro-amine curing agent is 30%-50% of the weight of the film-forming substances. The novel waterproof coating is strong in bonding strength, can be more closely combined with concrete, is more excellentin anti-permeability pressure and anti-permeability waterproof capability, larger in hydrophobic angle, better in waterproof effect and higher in compressive strength, has strong reinforcement and waterproof effects, is especially applicable to concrete ground and wall surfaces with poor structural force, and is high in solid content, green and pollution-free, and excellent in comprehensive performances.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a novel waterproof coating with penetrating hydrophobicity and multifunctionality, a preparation method and application thereof. Background technique [0002] Waterproof coatings are usually viscous liquid polymer synthetic materials that have no fixed shape at room temperature. According to the waterproof mechanism, waterproof coatings are mainly divided into two types of coatings: forming model (physical method) and penetrating type (chemical method). The chemical reaction forms a thin film to isolate the surface of the building from water, thereby playing the role of waterproof and sealing; the penetrating type refers to that after the paint is painted, in addition to forming a waterproof film on the surface of the coating, if the concrete cracks Or broken, the osmotic crystalline components in the coating can penetrate into the concrete structure, and react with calcium, so...
