Problems solved by technology

[0004] (2) Green plant adsorption: After several months of ventilation, the concentration of indoor formaldehyde will be greatly reduced, and the pollutants will enter a slow release process. The release cycle of formaldehyde is as long as 15 years. Some people will raise some plants indoors, such as Chlorophytum Plants such as green radish, agave, sansevieria, and ivy have certain adsorption capacity for formaldehyde, but the adsorption area is very limited and the adsorption efficiency is extremely low.
[0005] (3) Activated carbon adsorption: Activated carbon has the effect of adsorbing harmful substances such as formaldehyde, but it only adsorbs and does not decompose, and the adsorption capacity is limited, and it is easy to be saturated, so it needs to be replaced frequently, otherwise the saturated activated carbon will become a new source of pollution. Distribute harmful substances, causing secondary pollution
The porous structure of diatom mud allows it to absorb formaldehyde and various organic volatiles, but similar to activated carbon, diatom mud can only...

Abstract

The invention discloses a UV-curing coating with formaldehyde-removing function. The UV-curable coating with formaldehyde-removing function is prepared from the following raw materials in parts by mass: the total mass is 100 parts, 15-35 parts of light-sensitive polymer; 10-25 parts of thermoplastic resin; 35-65 parts of photoactive monomer; 1-5 parts of photosensitizer; 1-8 parts of catalytic catalyst; 5-10 parts of filler; 0.1-5 parts of dispersing agent; 0-1 part of defoaming agent. The invention also discloses a method for producing formaldehyde-removing product by using the UV-curing coating, which comprises the following steps of: (1) coating a UV-curing coating on a substrate, and preheating the coating by using infrared light, wherein the preheating temperature is 50-130 DEG C, andthe preheating time is 5 seconds-5 minutes; (2) after the preheating, curing with the ultraviolet light. The invention also discloses a formaldehyde removal product produced by above-mentioned method. The UV-curing coating has the advantages of low viscosity, high light-curing speed and no volatile organic solvent.

Description

technical field [0001] The invention relates to the field of ink and paint, in particular to a UV curable paint with a formaldehyde removal function, a formaldehyde removal product and a method produced therefrom. Background technique [0002] Decoration materials usually contain formaldehyde, toluene, TVOC and other pollutants that are harmful to human health, and the formaldehyde content in the newly renovated house will exceed the standard. At present, the technology of removing formaldehyde is mainly divided into two categories, one is physical removal of formaldehyde, and the other is chemical removal of formaldehyde. For example: [0003] (1) Open windows for ventilation: Ventilation is the most effective way to remove formaldehyde in a newly renovated house, and the air with high concentration of formaldehyde is continuously exchanged to the outside by opening windows. [0004] (2) Green plant adsorption: After several months of ventilation, the concentration of ind...
