Problems solved by technology

[0003] At present, the commonly used interior wall latex paint with hydrophobic effect is synthesized on the basis of ordinary interior wall latex paint by adding additives with hydrophobic function. The production cost of interior wall latex paint with high effect is relatively high. In addition, the film-forming aid contains a certain amount of volatile organic compounds (VOC), which also leads to a reduction in the environmental friendliness of this type of hydrophobic interior wall latex paint. In particular, This kind of interior wall latex paint containing external hydrophobic additives has poor recoatability and cannot be applied with two top coats, which cannot meet the two-coat application of flat-coated interior wall coatings in JGJ / T29-2015 "Code for Construction and Acceptance of Architectural Finishing Engineering" Therefore, this kind of hydrophobic interior wall latex paint also has the defects of poor film fullness and poor hand feeling.

Abstract

The invention relates to interior wall latex paint. The interior wall latex paint is prepared from, by weight, 10-17.5 parts of deionized water, 0.5-0.7 part of a dispersing agent, 0.15-0.2 part of awetting agent, 0.3-0.4 part of an antifoaming agent, 1.5-2.0 parts of propylene glycol, 0.5-1 part of alcohol ester-12, 18-20 parts of titanium dioxide, 10-12.8 parts of heavy calcium carbonate powder, 38-40 parts of a functional emulsion and 1-1.2 parts of a thickening agent. The pH value of the interior wall latex paint is 8-9. The interior wall latex paint has the advantages that the interior wall latex paint has a hydrophobic effect similar to lotus leaves, the recoatability is good, the plumpness of paint film is high, and the water resistance and stain resistance are excellent.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an interior wall latex paint with lotus leaf effect. Background technique [0002] Interior wall latex paint is one of the main decorative materials for interior walls and ceilings. It is characterized by good decorative effects, convenient construction, little environmental pollution, low cost, and a wide range of applications. Among them, the interior wall latex paint with hydrophobic effect has more and more broad application prospects because of its strong hydrophobic self-cleaning function. [0003] At present, the commonly used interior wall latex paint with hydrophobic effect is synthesized on the basis of ordinary interior wall latex paint by adding additives with hydrophobic function. The production cost of interior wall latex paint with high effect is relatively high. In addition, the film-forming aid contains a certain amount of volatile organic compounds (VOC), which also lea...
