Abstract
The invention discloses a UV (Ultraviolet) matte coating without other inorganic fillers such as silicon dioxide, wax powder, titanium dioxide and the like. A preparation method of the UV coating comprises the steps of taking acrylic ester with a melting point at a temperature of higher than 30 DEG C to mix with one or some of common epoxy acrylate, urethane acrylate and polyester acrylate, and preparing the UV coating with matte effect on the surface by using the characteristic that the acrylic ester has a crystal at normal temperature and low melting point and forming uneven structures on the surface of the crystal. The method is easy to operate and construct, easy to control, simple in control and low in cost.
Description
Technical field
The present invention relates to a kind of dumb light UV coating that does not contain the fillers such as dumb light powder.
Background technology
Most dumb light UV coating is all in UV regular convention formula, to add other mineral fillers such as silicon-dioxide, wax powder, titanium dioxide with dumb light effect, so no doubt can all reduce glossiness and reach required dumb light effect.But, in actual application, find the viscosity that adds membership and greatly increase formula of other mineral fillers such as silicon-dioxide, wax powder, titanium dioxide, make in construction process very inconvenient, also reduce in addition the avidity between film layer and bottom, in storage process, easily precipitate, greatly reduce the uniformity coefficient of coating, thereby hindered its result of use.Certainly will need so a kind of novel method that does not contain the fillers such as silicon-dioxide to reach same dumb light effect.Patent CN103031050A the inside has been introduced and has been prepared dumb light feel oil with dumb light resin and dumb light hand feeling agent etc., but the inside also has the wax of 2-8 part to starch.The low luster coatings such as patent CN1436824, CN1778852, CN101210144, CN101643624 all contain other mineral fillers such as silicon-dioxide, wax powder, titanium dioxide.
What the present invention relates to does not also report in document and patent containing the dumb light UV coating of the fillers such as dumb light powder.
Summary of the invention
For the viscosity that adds membership and greatly increase formula of other mineral fillers such as silicon-dioxide, wax powder, titanium dioxide, bring very large inconvenience to construction process.The present invention selects fusing point higher than the acrylate of 30 degrees Celsius, arrange in pairs or groups with one or more of conventional epoxy acrylate, urethane acrylate, polyester acrylate, utilize the characteristic at normal temperature lower melting propylene acid esters with crystallization, by form the surface whole structure that is uneven at surface crystallization, carrying out preparation table mask has the UV coating of dumb light effect.The method operating process construction easily, be easy to control, step is simple, with low cost.
