preparation example Construction

[0043] On the other hand, the embodiment of the present invention also provides a preparation method of an ultraviolet light curing primer for wood surface, comprising:

[0044] S01, weigh each component according to the formula of the above-mentioned UV-curable primer;

[0045] S02, the UV resin, the active monomer, the dispersant, the wetting agent, the non-silicon defoamer, the nitrocellulose pulp, the leveling agent and the anti-sedimentation The agent carries out the first mixed material treatment, obtains the first mixed material;

[0046] S03, adding the filler into the first mixture, performing a second mixing treatment to obtain a second mixture,

[0047] S04. Add the photoinitiator and the adhesion promoter into the second mixture, and perform a third mixture treatment to obtain the UV-curable primer.

[0048] Specifically, in the above step S02, the first mixing process is as follows: the temperature is below 50° C., the speed is 800-1000 rpm, and the stirring is ...

Embodiment 1

[0054] The content of each component by weight of the UV-curable primer provided in this embodiment is shown in Table 1:

[0055] Table 1

[0056] serial number

[0057] In the above table 1, the 100% UV resin is DSM’s UV resin Agisyn 705; the dispersant is BYK-103; the wetting agent is BYK-190; the non-silicon defoamer is Tego-920; the leveling agent is BYK-358 The anti-settling agent is Degussa brand R-972; the photoinitiator is Ciba company brand 1173; the filler is K brand talcum powder brand TP-3000; the active monomer is polyacrylic acid monomer of Cytec; adhesion promotion The agent is a modified phosphate ester.

[0058] The preparation method of the UV-curable primer provided in this embodiment is as follows:

[0059] S11: Weigh the raw materials of each component according to the components contained in the UV-curable primer in the above Table 1 and their parts by weight;

[0060] S12: Stir the above 100% UV resin, some active monomers, non-silicon defoa...

Embodiment 2

[0070] The content of each component of the UV-curable primer provided in this example is shown in Table 3 (in parts by weight).

[0071] table 3

[0072] serial number

[0073] In the above table 3, the 100% UV resin is DSM’s UV resin; the dispersant is BYK-103; the wetting agent is Rohm and Haas water-based coating wetting and dispersing agent; The leveling agent is BYK-358; the anti-settling agent is Degussa brand R-972; the photoinitiator is Ciba company brand 1173; the filler is K brand talcum powder brand TP-3000; the active monomer is polyacrylic acid of Cytec Monomer; adhesion promoter is a modified phosphate ester.

[0074] The preparation method of the UV-curable primer provided in this embodiment is basically the same as that in Embodiment 1, and will not be repeated here.

[0075] The above-mentioned ultraviolet curing primer is coated on the wood surface by spraying, and the amount of coating can be controlled by adjusting the air pressure of spraying,...

Abstract

The invention belongs to the technical field of coatings, and particularly relates to an ultraviolet curing primer for the surface of wood and a preparation method of the ultraviolet curing primer. Based on 100 parts of the total weight, the ultraviolet curing primer provided by the invention comprises the following components in parts by weight: 40-80 parts of ultraviolet (UV) resin, 2-4 parts ofa photoinitiator, 1-3 parts of a dispersing agent, 1-2 parts of a wetting agent, 0.05-0.2 part of a non-silicon deforming agent, 0-10 parts of nitrocotton pulp, 0.1-2 parts of a flatting agent, 0.1-1.0 part of an adhesion promoter, 0.1-2 parts of an anti-settling agent, 5-30 parts of active monomers and 5-30 parts of filler. Compared with the prior art, the ultraviolet light curing primer provided by the invention has good pore entering performance when the wood is sprayed and coated, filling efficiency of the primer is improved, coating times are reduced, and economic benefits are improved.In addition, a coating film formed by the primer has the characteristics of good filling, good polishing, high transparency and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an ultraviolet curing primer for wood surfaces and a preparation method thereof. Background technique [0002] UV curing coating is an environmentally friendly and energy-saving coating, its curing energy consumption is about 1 / 5 of that of heat curing, and it has no or very low volatile organic compound (VOC) emission characteristics, fast curing speed, low curing temperature, and energy saving Environmental protection, high production efficiency, suitable for assembly line production. UV-curable coatings are generally composed of oligomers, monomers, photoinitiators and additives. After ultraviolet radiation causes photoinitiators to decompose, active free radicals are generated to initiate polymerization and crosslinking of monomers or oligomers to form coatings. . In recent years, UV-curable coatings have developed rapidly in optical fiber coatings, CD coatings...
