Problems solved by technology

Among them, the use of oil-resistant plasticizers can modify the properties of the paint film, so that the paint film can achieve the properties of water resistance, easy cleaning, and increased strength, which overcomes the defects of water seepage, not easy to clean, and softness of traditional pulp; the use of natural polarity Negative ion minerals can release hydroxyl negative ions for a long time and achieve high-efficiency antibacterial properties; the beating denatured wood pulp solution is selected as the main film-forming substance, which can realize the function of natural degradation and also have the function of covering cracks on the wall surface; use oxidatively modified tapioca starch It can improve the workability of the coating, and the use of tapioca starch can also achieve the degradation function, and at the same time improve the opening time and viscosity strength of the coating; the inorganic filler can play a filling role

Abstract

The invention provides a degradable environment-friendly latex paint and a preparation method thereof. The degradable environment-friendly latex paint is prepared from the following components in percentage by mass: 16%-18% of water, 15%-20% of titanium dioxide, 3%-6% of natural-polarity anion mineral, 3%-5% of oxidative modified cassava starch, 1%-2% of an inorganic filler, 40%-50% of a pulping modified wood pulp solution, 1%-5% of an oil-resistant plasticizer and 1%-4% of a low-odor environment-friendly assistant. The degradable environment-friendly latex paint is a degradable product; the physical property of a product can be improved; and a film is water-resistant, easy to clean and high in strength, has the characteristics of being efficient and antibacterial, is beneficial to environmental protection and human health, and is an environment-friendly interior wall coating.

Description

technical field [0001] The invention relates to the field of building materials, more specifically, to a degradable environmental protection coating and a preparation method thereof. Background technique [0002] At present, the coatings on the market are made of synthetic resin emulsion as the base material, and the coatings are made by adding chemical additives containing APEO (alkylphenol polyoxyethylene ether compounds). Because it cannot be degraded, it will cause harm to ecology and water bodies, and affect the ecological environment; and ordinary wall paints also use synthetic resin emulsion as the base material, which cannot achieve the function of natural degradation. The wall paints sold on the market are only additives It has been replaced to reduce VOC (English abbreviation for volatile organic compounds) and other emissions, but also cannot achieve the effect of biodegradation. Because, in order to protect the environment, it is necessary to develop non-aquatic...
