Embodiment 1～6

[0031] The anti-scratch and stain-resistant interior wall coatings of Examples 1-6, the raw material ratio is listed in Table 1, and its preparation process includes the following steps:

[0032] S1. Add deionized water into the mixing container, turn on the high-speed disperser, adjust the dispersion speed to 200r / min, and then add component A (dispersant, wetting agent, thickener, pH regulator, preservative , defoamer) into the stirring container, then adjust the dispersion speed to 400r / min, stir and disperse for 5min to make it uniform;

[0033] S2. Adjust the dispersion speed to 1200-1500r / min, then add component B (pigment and filler) into the stirring container in turn, stir and disperse for 30 minutes to make the fineness reach ≤40um;

[0034] S3. Adjust the dispersing speed to 500-800r / min, and sequentially mix component C (graphene oxide, wax, antifreeze, film-forming aid, acrylic emulsion, silicone additive, the remaining defoamer and thickener agent) into the mixi...

Abstract

The invention provides an anti-scraping and stain-resistant interior wall coating and a preparation method thereof. The anti-scraping and stain-resistant interior wall coating is prepared from the following raw material components in percentage by mass: 10%-25% of deionized water, 0.4%-0.8% of a dispersing agent, 0.2%-0.3% of a wetting agent, 0.5%-1.5% of graphene oxide, 1%-3% of wax, 30%-40% of a flexible acrylic emulsion, 0.15%-0.25% of a preservative, 0.6%-1.0% of a defoaming agent, 1.5%-1.9% of an anti-freezing agent, 2.0%-2.4% of a coalescing agent, 2%-3% of a thickening agent, 0.05%-0.15% of a pH regulator, 0.5%-1.0% of an organic silicon additive, 15%-30% of pigment and 10%-20% of filler. According to the invention, the conventional flexible acrylic emulsion and graphene oxide are adopted, so that the scratch resistance, scratch resistance and adhesion resistance are improved, a strong resistance effect on various stains is achieved, and a paint film is always kept as new.

Description

technical field [0001] The invention belongs to the field of interior wall coatings, in particular to a scratch-resistant and stain-resistant interior wall coating and a preparation method thereof. Background technique [0002] Interior wall paint is generally latex paint, which is made of synthetic resin emulsion as the main film-forming substance, water as the dispersion medium, pigments, fillers and additives, and made through a certain process. With the improvement of people's living standards, people's requirements for interior wall coatings have gradually increased. Especially for functional rooms, such as children's rooms, kitchens, living rooms and other walls, the stain resistance performance is extremely high. It is necessary to be able to easily scrub all kinds of stains, so that the paint film will last forever, and at the same time, it has a similar ceramic tile Same excellent scratch and mar resistance. [0003] Generally speaking, the hardness of the paint f...
