Abstract

The invention discloses a formaldehyde removal coating and a preparation method thereof. The formaldehyde removal coating is prepared from, in parts by weight, 10-20 parts of styrene-acrylic emulsion,10-30 parts of shell powder, 0.05-0.3 part of an anti-settling agent, 2-6 parts of cellulose, 0.1-0.5 part of a dispersing agent, 0.1-0.5 part of a wetting agent, 0.1-0.3 part of an antifoaming agent, 0.5-2 parts of an antifreeze agent, 0-2 parts of a film-forming auxiliary, 5-30 parts of a filler, and 20-40 parts of water. The preparation method comprises the steps that the styrene-acrylic emulsion, the shell powder, the filler, the anti-settling agent, the cellulose, the dispersing agent, the wetting agent, the antifoaming agent, the antifreeze agent, the film-forming auxiliary and water are added to a reaction cylinder according to the above ratio, and a mixture is uniformly stirred to obtain the finished coating. The emulsion has good dispersion and wetting effects; the coating can well absorb volatile organic compounds such as formaldehyde; and the wet rubbing resistance is good.

Description

Technical field [0001] The invention relates to the technical field of environmental protection paint and its preparation, in particular to a formaldehyde removal paint and a preparation method thereof. Background technique [0002] Formaldehyde has a stimulating effect on the skin and mucous membranes. When the indoor environment reaches a certain concentration, people will feel uncomfortable, and even cause red eyes, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc. The newly renovated rooms contain high formaldehyde content, which is the main cause of many diseases. [0003] Shells are the mantle membrane of mollusks. They have a special kind of gland cells whose secretions can form calcifications that protect the soft parts of the body and become shells. my country has a vast sea area and is a big producer of marine shells. In recent years, the cultivation and processing of shellfish has become an important part of the econo...
