Embodiment 1

[0032] The interior wall paint of the present embodiment, in parts by weight, comprises:

[0033]

[0034] Wherein, the raw material of the degradable emulsion comes from the fruit extract of Gramineae, and the Gramineae is wheat.

[0035] Adopt above-mentioned composition to prepare the preparation method of interior wall paint, its preparation step comprises:

[0036] (1) Degradable emulsion, mix the gramineous fruit after pulverization, soak 48h at room temperature with 70% ethanol, concentrate the extract, dry it and grind it into powder to obtain the fruit extract, dissolve the fruit extract in water after pulverization , made into a 50% solution, together with an emulsifier, and a degradable emulsion was prepared by core-shell polymerization;

[0037] (2) Mix 15 parts of water, 20 parts of sodium silicate and 0.5 part of polysiloxane, stir evenly at a low speed, stir for 5 minutes, and rotate at 2000 rpm;

[0038] (3) Then add 0.3 part of defoamer and 0.25 part of d...

Abstract

The invention provides an interior wall coating. The coating comprises the following components in parts by weight: 10-40 parts of a silicate, 0.1-0.5 part of a dispersant, 20-40 parts of titanium dioxide, 0.1-0.5 part of an anti-foaming agent, 10-30 parts of water, 10-20 parts of a degradable emulsion, 0.1-0.5 part of cellulose, and 0.3-1 part of a silicate stabilizer, wherein raw materials of the degradable emulsion comes from fruit extracts of gramineous plants. The interior wall coating adopts the fruit extracts of the gramineous plants as the main preparation raw materials for the degradable emulsion, residual monomers in the emulsion are avoided, performances of a traditional interior wall coating can be reached, and main allergens (preservatives, mould inhibitors, film-forming auxiliary agents, antifreeze agents and residual monomers in the emulsion) are excluded, so that the probability of allergic reactions of skin contactors or respiratory inhalers is reduced. The invention also provides a preparation method of the interior wall coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an interior wall coating and a preparation method thereof. Background technique [0002] With the rapid development of the paint industry, various interior wall paints emerge in endlessly. Manufacturers attract the attention of consumers in terms of color, material and safety. Existing special paints for interior walls often have users appearing in the process of use. Skin itching, erythema rash, or dizziness and headache. According to the provisions of 1272 / 2008 in the REACH regulation, the main allergens mainly include preservatives, antifungal agents, film-forming aids, antifreeze agents, residual monomers in emulsions, etc. However, the current interior wall paint basically contains the above-mentioned preservatives, antifungal agents, film-forming aids, antifreeze agents, residual monomers in the emulsion, and the like. In particular, the emulsions in traditional interior...
