Abstract

The invention discloses an epoxy interior wall water-based paint. The epoxy interior wall water-based paint comprises a component A and a component B, wherein the component A is composed of the following components in percentages by weight: 20 to 40% of waterborne epoxy resin, 15 to 25% of distilled water, 5 to 10% of kaolin, 10 to 20% of titanium dioxide, 15 to 25% of diatom mud, 5 to 10% of shell powder, 0.5 to 1.0% of a dispersing agent, 1 to 2% of ethanol, 1 to 2% of a preservative, 0.2 to 0.5% of an antifoaming agent and 0.2 to 0.5% of a thickening agent; and the component B is composed of the following components in percentages by weight: 30 to 40% of a waterborne epoxy curing agent and 60 to 70% of distilled water. The invention provides a self-breathing, low-VOC and sound-absorbable epoxy interior wall water-based paint and a preparation method thereof. The water-based paint is applicable to public places like family places, meeting halls, classrooms and gyms, specifically to places with enclosed environments for long stay of people, or to the public places like meeting halls capable of hosting meetings.

Description

Technical field [0001] The invention relates to the field of coatings, in particular to an epoxy interior wall water paint and a preparation method thereof. Background technique [0002] In daily life, due to people's insufficient environmental protection awareness, most of the coatings used in daily life and public places are still paints or products that contain some harmful substances exceeding the standard, and some harmful gases will be volatilized. These products have serious harm to human physical and mental health. [0003] For example, VOC, VOC is the English abbreviation of Volatile Organic Compounds, which are commonly known as chemical substances harmful to the human body in wall paint (except heavy metals). These volatile organic compounds include formaldehyde, ammonia, ethylene glycol, esters and other substances. When VOC reaches a certain concentration, it can cause headache, nausea, vomiting, fatigue and other symptoms. In severe cases, it can even cause convulsio...
