Abstract

The invention provides an interior wall coating containing a formaldehyde catching agent and a preparation method thereof, and relates to the field of aqueous coatings. The composition comprises the following components in parts by weight: 50-60 parts of water-based hydroxyl acrylic emulsion; 30-40 parts of waterborne polyurethane emulsion; 3-10 parts of nanometer tin antimony oxide; 1-5 parts ofnanometer titanium dioxide; 10-15 parts of nanometer shell powder; 0.1-0.5 part of dodecanol ester, 0.5-1 part of carbon black, 3-6 parts of glyceryl monostearate, 1-3 parts of polydimethylsiloxane, 10-20 parts of a fiber type formaldehyde catching agent, 1-5 parts of sodium tripolyphosphate, 0.3-0.6 part of an antifoaming agent, 0.5-1 part of a thickening agent, 4-10 parts of propylene glycol butyl ether and 30-40 parts of deionized water. The interior wall coating is excellent in various technical indexes and reaches or exceeds the national standard and can be used on a large scale and has agood capture and elimination effect on indoor formaldehyde and can effectively protect human health of residents.

Description

technical field [0001] The invention relates to the field of water-based paints, in particular to an interior wall paint containing a formaldehyde scavenger and a preparation method thereof. Background technique [0002] The main hazard of formaldehyde is the irritation to the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. Formaldehyde concentrations greater than 0.08mg / m3 can cause red eyes, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc., and are the main cause of many diseases. [0003] Formaldehyde, which is harmful to the human body in daily life, can be said to be everywhere. The items involved include furniture, wooden floors; children's clothing, non-ironing shirts; fast food noodles, rice noodles; blistered squid, sea cucumbers, beef louvers, shrimps; and even cars. It is not difficult to see that formaldehyde has been involved in the four ...
