Embodiment

[0018] A kind of diatom ooze formaldehyde-removing indoor paint preparation process, described paint comprises the raw material composition of following ratio:

[0019] Diatomaceous earth 15-35%, dispersant 0.2-1%, surfactant 0.1-2%, modified starch 15-25%, synthetic emulsion 10-17%, nano-scale titanium dioxide 6-13%, talcum powder 5- 12%, filler 0-30%, silver ion antibacterial agent 0.5-2%, auxiliary agent 1-5%, emulsifier 0.3-0.5%, defoamer 0.2-0.5%, activated carbon 10-15 parts, the rest Water, the preparation technology of described coating comprises the steps:

[0020] Step 1: Put activated carbon and diatomaceous earth into a ball mill and mill for 1-1.5 hours. After ball milling, pass through a 300-450 mesh sieve to obtain a mixed powder for use;

[0021] Step 2: Pour water into the container and start stirring. During the stirring process, add modified starch, synthetic emulsion, and talcum powder in turn, and stir thoroughly;

[0022] Step 3: Heating and stirring th...

Abstract

The invention relates to a preparation process for a diatom mud formaldehyde-removing indoor coating. The coating mainly comprises the following components in percentages by mass: 15-35% of diatomaceous earth, 0.2-1% of a dispersant, 0.1-2% of a surfactant, 15-25% of modified starch, 10-17% of a synthetic emulsion, 6-13% of nano-sized titanium dioxide, 5-12% of talc powder, 0-30% of a filler, 0.5-2% of a silver ion antibacterial agent, 1-5% of an auxiliary agent, 0.3-0.5% of a wetting agent, 0.2-0.5% of a defoaming agent, 10-15% of activated carbon, and the balance of water. In a word, the coating provided by the invention has the advantages of a wide range of raw material sources, low price, safety, environmental protection, and strong formaldehyde-adsorbing ability.

Description

technical field [0001] The invention belongs to the technical field of decoration, and in particular relates to a preparation process of a decorative paint, in particular to a preparation process of a formaldehyde-removing diatom mud indoor paint. Background technique [0002] Formaldehyde is a transparent, colorless, irritating volatile gas. Living in an environment where formaldehyde exceeds the standard for a long time will cause severe irritation and edema of the respiratory tract, eye irritation, headache, and bronchial asthma. Direct skin contact with formaldehyde can cause dermatitis, stains, and necrosis. It may also cause chronic poisoning, mucosal hyperemia, skin irritation, and allergic dermatitis. Severe cases directly cause leukemia and lymphoma, causing life to be greatly threatened. Formaldehyde, as the most harmful gas to human beings, is known as the indoor "killer", especially in China, which seriously endangers the health of newly renovated families, es...
