Comparative example 1
Conventional uv curable matte resins.
The uv curable matte resins of examples 2 to 8, and the conventional uv curable matte resin of comparative example 1 were examined. The test results are shown in Table 1.
Table 1 test table for the properties of the uv curable matte resins of examples 2 to 8, and the conventional uv curable matte resin of comparative example 1
As can be seen from the test results in table 1, the uv curable matte resins provided in examples 2 to 8, which are synthesized by using polyester polyol, diisocyanate and hydroxy acrylate as main reactants, have uv curable matte resins, reduce the double bond density of the synthetic resins by using large molecular weight polyester polyol, suspend the matte powder on the surface of the coating layer by using monomers, and reduce gloss in two aspects, so that the synthesized resins have excellent matte properties. The ultraviolet-curable matte resin can be applied to the fields of spraying, roller coating, curtain coating and the like, has low price and good matte effect, and can reduce the gloss to about 5 degrees only by adding 3-5 points of matte powder. In addition, the resin also has good adhesive force and performance.
The foregoing is merely exemplary and illustrative of the structures of the present invention, which are described in some detail and detail, and are not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications are possible without departing from the inventive concept, and such obvious alternatives fall within the scope of the invention.
