Embodiment 1

[0025] The invention provides a new type of low-temperature resistant interior wall paint without ethylene glycol, comprising the following components: 35.8kg pure water, 0.5kg cellulose thickener, 0.7kg dispersant, 10.5kg rutile titanium dioxide, 13.2kg New composite styrene-acrylic emulsion, 2kg film forming agent, 0.3kg defoamer, 0.1kg thickener, 0.1kg antifungal agent, 9.8kg calcined kaolin, 22kg calcium carbonate, 5kg aluminum silicate.

[0026] Preferably, the novel composite styrene-acrylic emulsion includes 99.09wt% common interior styrene-acrylic emulsion, 4.55wt% neutral phosphate ester surfactant and 4.55wt% pure water.

[0027] In order to compare the performance with the existing ethylene glycol-containing coatings, 13.2kg of new composite styrene-acrylic emulsions were replaced with 12kg of ordinary interior wall styrene-acrylic emulsions and 1.2kg of ethylene glycol, and the remaining components and contents were consistent with those in Example 1. Ordinary form...

Embodiment 2

[0032] The invention provides a novel low-temperature-resistant interior wall paint without ethylene glycol, comprising the following components: 30kg of pure water, 0.8kg of cellulose thickener, 0.5kg of dispersant, 10kg of rutile titanium dioxide, 22kg of new composite benzene Acrylic emulsion, 3kg film former, 0.1kg defoamer, 0.3kg thickener, 0.4kg antifungal agent, 5kg calcined kaolin, 25kg calcium carbonate, 3kg aluminum silicate.

[0033] Preferably, the novel composite styrene-acrylic emulsion includes 99.09wt% common interior styrene-acrylic emulsion, 4.55wt% neutral phosphate ester surfactant and 4.55wt% pure water.

Embodiment 3

[0035] The invention provides a novel low-temperature-resistant interior wall paint that does not contain ethylene glycol, comprising the following components: 40kg of pure water, 0.4kg of cellulose thickener, 1kg of dispersant, 20kg of rutile titanium dioxide, and 11kg of new composite styrene-acrylic Emulsion, 4kg film former, 0.5kg defoamer, 0.5kg thickener, 0.3kg antifungal agent, 11kg calcined kaolin, 10kg calcium carbonate, 3kg aluminum silicate.

[0036] Preferably, the novel composite styrene-acrylic emulsion includes 99.09wt% common interior styrene-acrylic emulsion, 4.55wt% neutral phosphate ester surfactant and 4.55wt% pure water.

Abstract

The invention provides a novel ethylene-glycol-free low-temperature-resistant internal wall paint which comprises the following components in parts by mass: 30-40 parts of pure water, 0.4-0.8 part of cellulose thickener, 0.5-1 part of dispersing agent, 10-20 parts of rutile titanium white, 2-4 parts of film former, 0.1-0.5 part of defoaming agent, 0.1-0.5 part of thickener, 0.1-0.4 part of mold preventive, 5-11 parts of auxiliary material calcined kaolin, 10-25 parts of calcium carbonate, 3-5 parts of aluminum silicate and 11-22 parts of novel composite styrene-acrylic emulsion. On the premise of not increasing the production cost, the paint can still have favorable low-temperature stability, and can reduce the generation and discharge of volatile organic compounds.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a novel low-temperature-resistant interior wall paint not containing ethylene glycol. Background technique [0002] The general components of latex paint include: film-forming substances, pigments, solvents, and additives. Latex paint is a chemical mixture paint that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. The relatively authoritative book on paint technology in the Chinese paint industry defines it as follows: "Paint is a material that can be coated on the surface of an object by different construction techniques to form a solid film with firm adhesion, certain strength, and continuity. The film formed in this way is called coating film, also known as paint film or coating.” According to the classification of modern chemical products, coatings belong to fine chemical products. Coatings are gradually beco...
