Embodiment 1

[0050] Embodiment 1, when preparing 100kg film waterproof material, the asphalt of 48kg and the styrene-butadiene-styrene block copolymer of 15kg are mixed to obtain the negative ion emulsified asphalt that the vulcanized rubber of 63kg is modified, then with the nitrile of 32kg The rubber emulsion composed of rubber and EPDM rubber, and 5kg of additives are mixed to form a coating film waterproof material with a pH value of 7-13.5.

[0051] Among them, the additive consists of rosin soap and fatty acid soap with a total weight of 0.8kg, 1.5kg of condensed naphthalenesulfonic acid sodium salt, 1.0kg of alkyl sodium sulfate, and 0.5kg of hydrophilic 2-(2-hydroxyphenyl)- It consists of benzotriazole UV absorber, 0.2kg of calcium oxide defoamer and 1.0kg of N,N'-xylyl-p-phenylenediamine anti-aging agent.

Embodiment 2

[0052] Embodiment 2, when preparing 100kg coating film waterproof material, the asphalt of 45kg and the styrene-butadiene-styrene block copolymer of 15kg are mixed to obtain the negative ion emulsified asphalt of the vulcanized rubber modification of 60kg, then with 33kg of nitrile The rubber emulsion composed of rubber and EPDM rubber, and 7kg of additives are mixed to form a coating film waterproof material with a pH value of 7-13.5.

[0053] Among them, the additive consists of 2.6kg of alkyl diphenyl ether disulfonate, 2kg of condensed naphthalenesulfonic acid sodium salt, 0.8kg of alkyl sodium sulfate, 0.8kg of hydrophilic 2-(2-hydroxyphenyl)- It consists of benzotriazole UV absorber, 0.4kg of calcium oxide defoamer and 0.4kg of N,N'-xylyl-p-phenylenediamine anti-aging agent.

Embodiment 3

[0054] Embodiment 3, when preparing 100kg coating film waterproof material, the asphalt of 30kg and the styrene-butadiene-styrene block copolymer of 4kg are mixed to obtain the negative ion emulsified asphalt that the vulcanized rubber of 34kg is modified, then with 65kg of nitrile The rubber emulsion composed of rubber and EPDM rubber, and 1kg of additives are mixed to form a coating film waterproof material with a pH value of 7-13.5.

[0055] Among them, the additive consists of 0.5kg of nonylphenol ethoxylate, 0.1kg of condensed naphthalenesulfonate sodium salt, 0.3kg of alkyl sodium sulfate, 0.04kg of hindered amine light stabilizer, and 0.03kg of calcium oxide defoamer And 0.03kg of N,N'-xylyl-p-phenylenediamine anti-aging agent.

Abstract

The invention provides a method for preparing and applying a coating waterproof material, and the coating waterproof material. The method comprises the following steps: with a standard that the coating waterproof material accounts for 100 parts by weight, 20-90 parts by weight of vulcanized-rubber-modified anionic emulsified asphalt, 10-70 parts by weight of latex rubber and 0.1-10 parts by weight of an additive are mixed to form the coating waterproof material with a pH value of 7-13.5; the mixed coating waterproof material is coated onto a part to be coated with an injection method, and a mixed agent of a hardening agent and pure water is coated onto the part to be coated with an injection method at the same time; and the coating waterproof material is instantly subjected to a binding reaction with the mixed agent, such that a waterproof coating is formed through coagulation at the coated part. With the method provided by the embodiment of the invention, one or more functions of an existing water-based rubber asphalt coating waterproof material can be improved.

Description

technical field [0001] The invention relates to the field of nanocomposite materials, in particular to a method for preparing and constructing a film-coated waterproof material, and a film-coated waterproof material. Background technique [0002] Film-coated waterproof materials are generally water-based or oil-based waterproofing agents, which are sprayed or painted onto various buildings and civil structures, and then applied to form a film after evaporation of water or solvents to exert a waterproof effect. [0003] Such coating film waterproofing materials have been represented by polymer solution-type reactive resins such as epoxy resins and polyurethane resins, and modified asphalt has become the mainstream, but these are mostly solvent-based or melt-processed types, which have problems such as causing environmental pollution. In order to replace these materials, recently, the tendency to mix water-based rubber emulsion and emulsified asphalt is increasing. [0004] S...
