Abstract

The invention discloses a wallpaper intaglio printing size capable of cleaning indoor air. The wallpaper intaglio printing size capable of cleaning indoor air is prepared from the following raw materials in parts by weight: 3-5 parts of air cleaning particle, 4-6 parts of hyacinth bletilla powder, 5-20 parts of dioctyl phthalate, 30-50 parts of polyvinyl chloride paste resin, 1-5 parts of D80 environment-friendly solvent oil, 10-30 parts of calcium carbonate, 1-3 parts of carboxymethyl cellulose, 1-5 parts of stabilizer, 5-8 parts of VAE (vinyl acetate-ethylene) emulsion, 10-20 parts of silicon dioxide, 1-3 parts of thickener and 1-3 parts of drying rate regulator. The size has transparent effects, and thus, can not influence the visual effect of the wallpaper. The size can clean the indoor air and lower the noise, and has the effects of resisting mildewing, protecting the pattern and color printed on the wallpaper surface and enhancing the scratch resistance of the wallpaper surface. The invention also discloses a preparation method of the wallpaper intaglio printing size capable of cleaning indoor air. The preparation method has the advantages of simple technical steps, low facility requests and high operability, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a slurry for wallpaper printing, in particular to a wallpaper gravure printing slurry capable of purifying indoor air and a preparation method thereof. Background technique [0002] As we all know, the toxic substances released from house decoration materials include formaldehyde, toluene diisocyanate, organic volatiles, asbestos, ammonia, radon, etc., and nearly 20 of them have been identified as carcinogens and mutagens. Among them, we inadvertently opened the "Pandora's box" of air pollution while decorating-artificial panel adhesive (urea-formaldehyde resin glue) is one of the reasons for long-term release of formaldehyde, causing indoor air pollution for several years. However, formaldehyde is highly carcinogenic. It can be seen that indoor air pollution in newly renovated houses is very likely to seriously affect health and even cause cancer. Therefore, the selection of materials is more critical. [0003] The use of wal...
