Problems solved by technology

However, this type of matting agent will generate a lot of dust during use, and usually needs to be used with a solvent, so the content of volatile organic compounds (VOC) may be too high, which does not meet environmental protection requirements
In addition, general radiation curing coatings do not contain solvents, and the low shrinkage rate of radiation curing coatings will affect the matting effect of silica
Increasing the amount of silica may solve the problem of poor matting effect, but may have negative effects, such as reducing the rheology of the coating, etc.

Embodiment approach

[0040] According to a preferred embodiment of the present invention, the acrylate monomer of the formula (V) has the formula (V 1 ):

[0041]

[0042] where Y 5 'is methyl or isopropyl; Y 4 ' is hydrogen or methyl; m' is an integer selected from 6 to 12.

[0043] The present invention further provides a method for preparing a matting composition, which comprises:

[0044] (a) modifying the clay with a quaternary ammonium cation selected from the group consisting of a quaternary ammonium cation of formula (I), a quaternary ammonium cation of formula (II), or a mixture thereof to produce a modified clay; and

[0045] (b) combining the modified clay prepared in step (a) with at least one acrylate monomer (preferably at least one acrylate monomer selected from formula (III) and formula (IV)) and optionally Another acrylate monomer (preferably the acrylate monomer of formula (V)) that is incompatible with the above-mentioned acrylate monomer is mixed to prepare a matting co...

preparation example

[0050] Preparation of modified clay

[0051] Stir and disperse 20 grams of clay [China Glaze Company, model CN-C34], 8 grams of octadecyltrimethylammonium chloride and 5 grams of methacryloxyethyltrimethylammonium chloride in 100-400ml of ethanol Mix the solution with water (weight ratio 1:1), gradually raise the temperature to 50-85°C, keep it for 8-12 hours, then cool down and filter, and then fully wash with the mixed solution of ethanol and water until it is washed with 0.1M AgNO 3 The solution does not detect Cl - Until it exists, it is vacuum-dried and pulverized and passed through a 200-mesh sieve for subsequent use.

[0052] Preparation of matting composition A of the present invention

[0053] The modified clay prepared above was mixed with monomer EM222 (dipropylene glycol diacrylate, purchased from Eternal Chemical Co., LTD.), and stirred for 10 to 24 hours to make it uniformly dispersed. The content of modified clay is about 30 wt%, and the content of monomer EM...

Embodiment 13-20

[0066] Mix the matting composition A and matting composition B of the preparation example with the ultraviolet curable resin, disperse evenly and coat it on the cardboard, after the ultraviolet light curing coating, detect its 60 ° gloss, and record the results in Table 2 middle. For comparison with known matting agents, the amount of matting composition A is to make the amount of modified clay (inorganic substance) contained therein reach 1.5, 3, 4.5 and 6 grams; in addition, depending on the content of matting composition A and matting composition B With the increase of monomer amount, increase the amount of photoinitiator Darocur1173 appropriately.

[0067]

[0068]From the results in Table 1 and Table 2, it can be seen that increasing the amount of matting agent can achieve the effect of reducing gloss. Comparing the results of Comparative Examples 1-12 and Examples 13-16, it can be seen that in the known matting agent TS100 or the matting agent method containing only ...

Abstract

The invention provides an extinction composition, which comprises modified clay and at least one acrylic ester monomer, wherein the content of the modified clay accounts for at least 0.5 percent of the total weight of the extinction composition. The extinction composition can be used for radiation curing coatings, and has the characteristics of convenient operation, stable glossiness and the like.

Description

technical field [0001] The invention relates to a matting composition, especially a matting composition applicable to radiation-cured coatings. Background technique [0002] With the improvement of living standards, consumers' aesthetic concepts are more and more inclined to leisure, fashion and personalization. Therefore, bright-colored high-gloss coatings are gradually no longer favored by consumers. On the other hand, after high-gloss coatings are formed into films The reflection is serious, and it is easy to hurt the eyes of the observer. On the contrary, the coating with low gloss can greatly reduce the eye damage of the observer, and can hide small defects on the surface of the coating, so that it has a satisfactory Appearance, therefore, is particularly suitable for applications in wood, furniture or interior decoration of various vehicles. Matting is the use of various methods to reduce the gloss of the coating. The glossiness of the coating mainly depends on the s...
