Abstract

The invention discloses a coating slurry formula capable of effectively removing formaldehyde to achieve the purpose of purifying air. The coating slurry formula comprises the following components in parts by weight: 100 parts of pure acrylate soft emulsion, 35-45 parts of pure acrylate hard emulsion, 16-24 parts of a foam stabilizer, 24-36 parts of titanium dioxide slurry, 4-12 parts of modified zeolite, 0.5-1 part of a thickening agent and 0.5-1 part of a dispersing agent. The preparation method of the coating slurry for removing formaldehyde and purifying air comprises the following steps: S1, weighing; S2, fully mixing titanium dioxide, modified zeolite and a formaldehyde scavenger, and uniformly dispersing; S3, uniformly dispersing pure acrylate emulsion; S4, putting the titanium dioxide slurry obtained in S2 into the emulsion obtained in S3, stirring and dispersing uniformly; and S5, adding a thickening agent to adjust the viscosity of the slurry.

Description

technical field [0001] The invention relates to the technical field of curtain coating coatings, in particular to a preparation method for coating slurry that can effectively remove formaldehyde and purify air. Background technique [0002] Polymer coatings have very important applications in industries such as textile printing and dyeing, modern house decoration, and furniture manufacturing. Because of their simple preparation process, low price, improved product aesthetics and excellent performance, they are very popular in the market. [0003] However, this polymer coating will continue to slowly release organic volatiles such as formaldehyde under conditions such as light. Formaldehyde is highly carcinogenic. On October 27, 2017, in the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization, formaldehyde has been placed in the list of carcinogens, so the release of formaldehyde volatiles has seriously affected F...
