Problems solved by technology

These organic solvents will volatilize into the atmosphere, causing health hazards to production, construction and user personnel, and causing environmental pollution, and there are serious fire hazards
The organic compounds volatilized into the atmosphere react photochemically with nitrogen oxides in the presence of ultraviolet light (sunlight) to form smog and pollute the environment, damage human health, lead to crop yield reduction, accelerated material aging and ecological system damage

Embodiment 1

[0038] A kind of low VOC environmental protection building waterproof coating, its preparation method is as follows:

[0039]Add 3 parts of water into the container, disperse with a disperser at a suitable speed, add 0.01 part of thickener (BERMOCOLLEHM300, a composite non-ionic water-soluble cellulose ether) to completely dissolve, and continue to add 0.25 parts in sequence 5040 polycarboxylate dispersant, 0.4 parts of defoamer (SPA202 and DFC17 compounded at 1:1), 0.05 parts of multifunctional additive (AMP-95), and then add 3 parts of titanium dioxide, 25 parts of filler (including weight 10 parts of calcium carbonate, 10 parts of barite powder, and 5 parts of talc powder), and disperse to the required fineness to obtain a dispersion slurry.

[0040] Mix 0.4 parts of defoamer (SPA202 and DFC17 compounded at 1:1), 30 parts of emulsion (including 20 parts of low-VOC pure acrylic emulsion, 9 parts of low-VOC vinyl acetate-ethylene emulsion, soap-free silicone rubber) at a cert...

Embodiment 2

[0042] A kind of low VOC environmental protection building waterproof coating, its preparation method is as follows:

[0043] Add 4.5 parts of water into the container, disperse with a disperser at a suitable speed, add 0.03 parts of thickener (BERMOCOLLEHM300, a composite non-ionic water-soluble cellulose ether) to completely dissolve, and continue to add 0.35 parts in sequence 5040 polycarboxylate dispersant, 0.6 parts of defoamer (SPA202 and DFC17 compounded at 1:1), 0.1 part of multifunctional additive (AMP-95), and then add 4.5 parts of titanium dioxide, 35 parts of filler (wherein weight 10 parts of calcium carbonate, 20 parts of barite powder, and 5 parts of talc powder), and disperse to the required fineness to obtain a dispersion slurry.

[0044] Mix 0.2 parts of defoamer (SPA202 and DFC17 compounded at 1:1), 55 parts of emulsion (including 25 parts of low-VOC pure acrylic emulsion, 29 parts of low-VOC vinyl acetate-ethylene emulsion, soap-free silicone rubber) at a c...

Embodiment 3

[0046] A kind of low VOC environmental protection building waterproof coating, its preparation method is as follows:

[0047] Add 6.5 parts of water into the container, disperse with a disperser at a suitable speed, add 0.05 parts of thickener (BERMOCOLLEHM300, a composite non-ionic water-soluble cellulose ether) to completely dissolve, and continue to add 0.55 parts in sequence 5040 polycarboxylate dispersant, 0.6 parts of defoamer (SPA202 and DFC17 compounded at 1:1), 0.25 parts of multifunctional additive (AMP-95), and then add 6 parts of titanium dioxide, 45 parts of filler (wherein weight 30 parts of calcium carbonate, 10 parts of barite powder, and 5 parts of talc powder), and disperse to the required fineness to obtain a dispersion slurry.

Abstract

The invention discloses an environment-friendly building waterproof paint with a low content of VOC (volatile organic compound) and a preparation method thereof. The paint comprises the following components in parts by weight: 3 to 6.5 parts of water, 0.01 to 0.05 part of thickening agent, 0.25 to 0.55 part of dispersant, 0.4 to 0.8 part of antifoaming agent, 0.05 to 0.25 part of multifunctional auxiliary agent, 0.05 to 0.15 part of antiseptic, 3 to 6 parts of titanium dioxide, 25 to 45 parts of filling material, 30 to 60 parts of emulsion, and 1 to 2 parts of rheological additive. The paint is prepared by a ternary compounding technology, which compounds three components: low-VOC pure acrylic emulsion, low-VOC vinyl acetate-ethylene emulsion, and soap-free organic silicon rubber emulsion; a VOC-free composite rheological system blending technology and a composite silver ion sterilizing and anticorrosion technology. The paint has the advantages of low VOC content, green, no toxicity, high strength, convenience in construction, and stableness in storage.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a low-VOC environmental protection building waterproof coating and a preparation method thereof. Background technique [0002] Architectural waterproof coatings are referred to as waterproof coatings. At present, waterproof coatings on the market can be divided into asphalt, polymer modified asphalt, synthetic polymers, inorganic cement, polymer cement and other types according to the film-forming base material. Among them, synthetic polymers can be divided into two types: solvent-based and water-emulsion-type products, especially water-emulsion-type one-component waterproof coatings because they are easy to operate and can be constructed on relatively humid screeds, and they are easy to produce, store, and transport , Construction and other links are relatively safe and widely used. [0003] However, with the development of society and economic level and ...
