Waterproof/sealing paint with aqueous resin as main body

Abstract

The invention discloses a waterproof / sealing paint with an aqueous resin as the main body. The aqueous resin is a formula resin which is prepared according to a patent of the applicant of the invention, the aqueous resin and an aqueous hardener are dispersed in an emulsion, and the obtained material which is coated on surfaces of buildings, timbers, rattan articles or metals becomes hard to form a hard and waterproof film after water is evaporated and the aqueous resin penetrates the surface of above objects. The extremely good durability and the extremely waterproof performance are reached, and the exudation of impurities in the objects is sealed, so the influence of the exudation of the impurities in the objects to a next step japanning of the objects is avoided. Compared with general waterproof paints and sealing coats, the waterproof / sealing paint of the invention simultaneously has the functions of waterproof paints and sealing paints, the waterproof / sealing paint which is an aqueous system can be diluted with water, and the waterproof / sealing paint which contains an extremely small amount of organic solvents contains no formaldehyde and no toluene, so the waterproof / sealing paint which has the advantages of environment protection and low usage cost avoids the cost of solvents for diluting the waterproof / sealing paint. The waterproof / sealing paint can be applied to various objects of interior walls and exterior walls of buildings, timbers, metals, rattan articles, paper, various handicrafts and the like.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based resin-based waterproof / sealed coating and a preparation method thereof. Background technique [0002] Due to the development of society, people's building quality is getting higher and higher. Among them, the tolerance for water leakage and water seepage in buildings is getting lower and lower, and the environmental protection requirements for building materials are also getting higher and higher. At the same time, in addition to waterproof In addition to the requirements, people also hope that the waterproof coating can seal the seepage of impurities inside the coated material, so that it will not be affected by the impurities inside the material during the next surface coating. Traditional waterproof coatings are generally oil-soluble and must be coated with toluene, etc. Highly toxic organic solvents can be used only after dilution, while oil-soluble paints have limited penetration a...

AI Technical Summary

Problems solved by technology

Solvent-free resins often have to add reactive diluents to reduce their viscosity. Generally, reactive diluents are expensive, and some reactive diluents are volatile, which are as harmful as solvents or even more serious. Using oily solvent-free resins, Its affinity to the surface of hydrophilic buildings is not good, and the film formed after drying is relatively easy to fall off; and if a water-based topcoat is applied to the surface of the waterproof coating, its lipophilic surface has a poor affinity to the water-based topcoat. .
