preparation example Construction

[0030] On the other hand, the embodiment of the present invention also provides a kind of preparation method that is used for sealing the ultraviolet curing coating of pine turpentine, comprises the following steps:

[0031] S01, each component is weighed according to the formula of the UV-curable coating of pine wood turpentine described in the embodiment of the present invention;

[0032] S02, subjecting the water-soluble UV resin, polyester acrylate resin, polyurethane acrylate, wetting agent, defoamer and leveling agent to a first mixing treatment to obtain a first mixing product;

[0033] S03. Add the photoinitiator and active monomer into the first mixture, and perform a second mixture treatment to obtain the UV-curable coating of sealed pine turpentine.

[0034] The preparation method of the UV-curable coating for sealing pine wood turpentine provided by the embodiment of the present invention has the characteristics of simple process, low cost and high efficiency; when...

Embodiment 1

[0038] The content of each component by weight of the UV-curable coating provided in this embodiment is shown in Table 1:

[0039] Table 1

[0040]

[0041]

[0042] In the above table 1, the polyester acrylate resin is Boxing Chemical B522; the wetting agent is BYK-190; the defoamer is non-silicon defoamer Tego-920; the leveling agent is BYK-358N; It is Ciba's trademark 1173; the active monomer is Cytec's polyacrylic acid monomer.

[0043] The preparation method of the UV-curable coating provided in this embodiment is as follows:

[0044] S11: Weigh the raw materials of each component according to the components contained in the UV-curable coating in the above Table 1 and their parts by weight;

[0045] S12: Stir the above-mentioned water-soluble UV resin, polyester acrylate resin, polyurethane acrylate, wetting agent, defoamer, and leveling agent at a temperature below 50°C and a speed of 800-1000 rpm for 10-15 minutes.

[0046] S13: Then add photoinitiator and some...

Abstract

The invention belongs to the technical field of paint, and particularly relates to an ultraviolet curing paint for sealing pine turpentine and a preparation method thereof. The ultraviolet curing paint comprises the following components in parts by weight: 10-60 parts of water-soluble UV resin; 5-30 parts of polyester acrylate; 5-20 parts of urethane acrylate; 2-4 parts of a photoinitiator; 1-2 parts of a wetting agent; 0.05-0.2 parts of a defoaming agent; 0.1-2 parts of a leveling agent; and 5-30 parts of an active monomer. According to the ultraviolet curing paint for sealing the pine turpentine, the sealing effect of the turpentine in pine wood can be improved, the risk of delaminating and falling of a paint film is reduced, and the decorative effect of a product is improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an ultraviolet curing coating for sealing pine turpentine and a preparation method thereof. Background technique [0002] In furniture painting, some woods contain heavy oils, such as pine containing turpentine. Due to the oil contained in these woods, it is difficult to guarantee the adhesion of the paint when the furniture is painted. In places with heavy oil, there may be no adhesion, and the paint may directly delaminate and fall off. [0003] At present, water-based UV (ultraviolet light) coatings are more effective in sealing pine turpentine, but due to the low solid content during construction, generally less than 40%, the filling is not enough, and the sealing effect is relatively poor in places where turpentine is heavier. Difference. Therefore, the prior art needs to be improved. Contents of the invention [0004] The purpose of the present invention is to provide...
