preparation example Construction

[0035] The preparation step of the embodiment of the present invention is to add the powder in the formula (such as powdered additives, etc.) , slowly put in epoxy acrylate and ABS resin, disperse for 10-20min, put in photoinitiator, stir and disperse for 35-40min, add the remaining reactive diluent and dispersant, add defoamer, stir evenly, and obtain UV curable coating. The specific formulation is described in the following examples.

[0036] The selected components of the embodiment are as follows: the diluent such as CYTEC, SARTOMER, Changxing, Miki or their mixture; the defoamer such as tego920, tego931 produced by Tego Company or their mixture; the dispersant Such as tego685, tego655 produced by Tego Company or their mixtures; the initiator such as TPO produced by BASF, CIBA 184, 1173 or their mixtures; the pigment is rutile titanium dioxide, such as TR92 of HUNTSMAN.

Abstract

The invention discloses a UV (Ultraviolet) curable coating, which is characterized in that the coating comprises the following components in parts by weight: 35-55 parts of epoxy acrylate, 0-55 parts of ABS (Acrylonitrile Butadiene Styrene) resin, 12-18 parts of diluting agent, 1-2 parts of photo-initiator, 23-40 parts of filler and 0.05-1 part of gas-phase silicon dioxide. The UV curable coating is obtained by matching the epoxy acrylate and the ABS resin; and a cured film of the obtained coating has high hardness and superior heat resistance and chemical resistance performance, and also has good flexibility and superior aging resistance and yellowing resistance performance.

Description

technical field [0001] The invention relates to a UV light-curing paint, in particular to a UV color paint with good covering and good adhesion. Background technique [0002] UV is the English abbreviation for Ultra-Violet Ray. The industrial UV wavelength ranges from 200nm to 450nm. The "UV radiation hardenable material" is hardened by irradiating it with UV. UV coatings can be coated by dip coating, flow coating, paint coating, spin coating, or even vacuum coating, and then cured by ultraviolet photon irradiation to form a film. As the name implies, the curing of UV coatings is inseparable from the irradiation of UV light. UV curing coatings originated in the international coatings market in the 1970s and are a new green technology. Utilize this technology to produce the UV-curable coating, referred to as UV coating. At the end of the 20th century, UV curing coatings became popular in the West, Japan and other places, and they are a kind of coating varieties represent...
