Embodiment 1

[0089] Use a grinder to grind the green tea leaves at high speed. Only fine particles having a particle size of 0.02 to 125□ were screened out of the fine particles sorted by the blower. After the paint raw materials were well mixed, green tea powder was added to the paint raw materials having the contents shown in Table 4 and dispersed to obtain UV paint. In Table 4, urethane acrylate and epoxy acrylate were used as oligomers (60 wt %), and styrene monomers or acrylate monomers including dipentaerythrytol hexaacrylate were used as monomers (25wt%), and photoinitiator (4wt%), additive (1wt%) and extender (8wt%) with two or more functional moieties were used. The paint raw material is AULEX893FK-HV and No. 050404 green tea (2wt%) is added.

[0091] components

Embodiment 2

[0093] A UV paint was prepared in the same manner as in Example 1, except that 7 wt % of an extender pigment and 2.5 wt % of green tea powder were used.

Embodiment 3

[0095] A UV paint was prepared in the same manner as in Example 1 except that 7 wt % of the extender pigment and 3 wt % of green tea powder were used.

Abstract

Provided is a functional UV paint including a flavonoid compound, a steroid compound, a polyphenol compound, or a mixture thereof, in which molecular weights of the compounds range from 250 to 1000. The UV paint can reduce VOCs of a product using the paint as well as VOCs and HCHO of the paint itself.

Description

technical field [0001] The present invention relates to a functional UV paint, a construction material using the paint and a method for preparing the paint, and more particularly, to a UV paint comprising additives or pigment fillers instead of UV curable paint components Dry plant powder etc. to reduce various volatile organic compounds (VOC) and remove formaldehyde (HCHO), thereby providing an environmentally friendly coating composition and minimizing the emission of harmful compounds produced by the building materials to which the coating is applied and thus improve indoor air quality in human dwellings. Background technique [0002] Among a variety of pollutants affecting indoor air quality, VOC and HCHO have an impact on the human nervous system, respiratory organs and circulatory organs, thus reducing the sensitivity of the peripheral nervous system and having carcinogenicity and as shown in Table 1 (VOC and HCHO produced indoors) its impact) and toxicity shown in Ta...
