Embodiment 1

[0026] Step 1: Add 15g of benzene into the reaction vessel and heat to 65-70°C; add 2g of dodecyl methacrylate, 15g of hydroxypropyl methacrylate, 40g of styrene, 10g of methyl methacrylate, 6g of methyl Butyl acrylate and 2g vinyltrimethoxysilane were mixed uniformly to obtain the monomer phase;

[0027] 10g of benzene and 1.875g of azobisisobutyronitrile were mixed to obtain an initiator solution;

[0028] Step 2: Add the monomer phase and 70-80% initiator solution dropwise to the reaction vessel in step 1 at the same time, and add dropwise for 3 hours under the protection of an inert gas;

[0029] Step 3: Add the remaining initiator into the reaction vessel at one time, keep it warm at 70-75°C for 1 hour, and finish the reaction.

Embodiment 2

[0031] Step 1: Add 18g of benzene into the reaction vessel and heat to 65-70°C; add 4g of dodecyl methacrylate, 15g of hydroxypropyl methacrylate, 30g of styrene, 12g of methyl methacrylate, 8g of methyl Butyl acrylate and 3g vinyltrimethoxysilane were mixed uniformly to obtain the monomer phase;

[0032] 10g of benzene and 2.16g of azobisisobutyronitrile were mixed to obtain an initiator solution;

[0033] Step 2: Add the monomer phase and 70-80% initiator solution dropwise to the reaction vessel in step 1 at the same time, and add dropwise for 3 hours under the protection of an inert gas;

[0034] Step 3: Add the remaining initiator into the reaction vessel at one time, keep it warm at 70-75°C for 2 hours, and finish the reaction.

Embodiment 3

[0036] Step 1: Add 20g of benzene into the reaction vessel and heat to 65-70°C; add 3g of dodecyl methacrylate, 12g of hydroxypropyl methacrylate, 35g of styrene, 11g of methyl methacrylate, 7g of methyl Butyl acrylate and 2g vinyltrimethoxysilane were mixed uniformly to obtain the monomer phase;

[0037] 10g of benzene and 2.16g of azobisisoheptanonitrile were mixed to obtain an initiator solution;

[0038] Step 2: The monomer phase and 70-80% initiator solution are simultaneously added dropwise to the reaction vessel of step 1, and added dropwise for 2 hours under the protection of an inert gas;

[0039] Step 3: Add the remaining initiator into the reaction vessel at one time, keep it warm at 70-75°C for 2 hours, and finish the reaction.

Abstract

The invention belongs to the field of resins for coating materials, and discloses a water sticker gloss high-hydroxy acrylate resin, which is prepared from the following components by weight: 2-4 parts of dodecyl methacrylate, 10-15 parts of a hydroxy acrylate monomer, 30-40 parts of styrene, 10-12 parts of methyl methacrylate, 6-8 parts of butyl methacrylate, 2-3 parts of a polymerizable organosilicon monomer and an azo-based free radical initiator, and a solvent, wherein the azo-based free radical initiator accounts for 2.5-3% of the total amount of the monomer, and the solid content of theresin solution after the reaction is 70-75%. According to the present invention, with the application of the resin in water stickers, the resin exhibits excellent adhesion, excellent wettability, excellent gloss and excellent fullness.

Description

technical field [0001] The invention relates to the field of resins for coatings, in particular to a high-hydroxyl acrylic resin for varnishing water stickers and a preparation method thereof. Background technique [0002] At present, under the existing technical conditions, the adhesion of most resins is not good, especially the adhesion of the ink surface of the water sticker. There is poor leveling, and it is easy to shrink and produce small orange lines. [0003] At the same time, in the process of water transfer printing, there are still problems of adhesion, wettability, gloss, and fullness. [0004] In the field of coatings, adhesion promoters are used to improve adhesion, such as epoxy phosphate, [0005] The improvement of wetting performance is mostly carried out by silicone, which can reduce surface tension and improve wetting performance. For example, CN201710588302.9 discloses a silicone-based high-efficiency wetting agent. Mainly through organic fluorine-pol...
