Embodiment 1

[0027] An ultraviolet odor-cleaning paint is made of the following raw materials in parts by weight:

[0028] 45-60 parts of macromolecular photocurable resin; 10-35 parts of silicon-modified photocurable monomer; 10-35 parts of other monomers; 0-20 parts of powder; 1-5 parts of auxiliary agent; share.

[0029] Other monomers are all toluene-free reactive monomers.

[0030] A preparation method for an ultraviolet odor-cleaning paint, comprising the following steps:

[0031] First mix the macromolecular photocurable resin, silicon-modified photocurable monomer and other monomers evenly, then add additives and photoinitiators and mix evenly, and finally add powder, mix evenly to obtain the ultraviolet odor-cleaning paint.

Embodiment 2

[0033] The preparation method of macromolecular photocurable resin comprises the steps:

[0034] 1. First add diisocyanate, polyester polyol or polyether polyol and catalyst I into the reaction vessel according to the proportion, mix evenly, fill with nitrogen, react at 60℃~70℃, keep warm for 2.0h~4.0h, Detect the NCO% content in the reaction process;

[0035] 2. When the NCO% content is close to the theoretical value, add dried hydroxyurea for chain extension reaction, keep the temperature at 65°C to 80°C for 2.0h to 4.0h, and then detect the NCO% content in the reaction process;

[0036] 3. When the NCO% content is close to the theoretical value, add polymerization inhibitor II and monohydroxy acrylate monomer, react at 65°C-85°C for 2.0h-3.0h, detect the NCO% content in the reaction process, when the NCO% content When it is less than 0.1%, the reaction temperature is lowered to below 60°C to obtain a macromolecular photocurable resin.

[0037] Diisocyanates are hexamethyl...

Embodiment 3

[0044] The preparation method of silicon-modified photocurable monomer comprises the steps:

[0045] Add multifunctional photocurable monomer, catalyst II, and polymerization inhibitor II into the reaction bottle, and gradually raise the temperature to 95-130°C, then add hydrogen-containing silicone oil dropwise, and keep warm at 120-140°C for 8.0-10.0 h, sampling and using infrared spectroscopy to detect silicon-hydrogen bond peaks;

[0046] After the sampling test is qualified, the temperature is lowered and the material is discharged to obtain a silicon-modified light-curable monomer.

[0047] The multifunctional photocurable monomer is one or more of pentaerythritol tetraacrylate, pentaerythritol triacrylate, di(trimethylolpropane) tetraacrylate, dipentaerythritol hexaacrylate, and dipentaerythritol pentaacrylate;

[0048] Hydrogen-containing silicone oil is a long-chain low-hydrogen-containing silicone oil with a hydrogen content of 0.1-0.22% and an average molecular wei...

Abstract

The invention relates to a paint, especially a UV deodorizing paint, which is made of the following raw materials in parts by weight: 45-60 parts of macromolecular photocurable resin; 10-35 parts of silicon-modified photocurable monomer; 10-35 parts of body; 0-20 parts of powder; 1-5 parts of auxiliary agent; 0.1-1 part of photoinitiator. The ultraviolet deodorizing paint provided by the invention adopts macromolecules, no aldehyde, no peculiar smell, no benzene series, and ultra-low VOC emission; it can be applied to the fields of home building materials, automobile manufacturing, consumer electronics, etc. Odor release issues during curing.

Description

technical field [0001] The invention relates to a coating, in particular to an ultraviolet deodorizing coating and a preparation method thereof. Background technique [0002] Coatings are closely related to our lives. During the construction process, traditional coatings will release harmful substances - formaldehyde, benzene series, volatile organic compounds, heavy metals, etc., causing adverse effects on the environment and human body. The smell of paint mainly comes from the following two aspects: [0003] (1) Small molecule volatiles produced when the coating is cured; [0004] (2) Small molecule volatiles contained in the paint itself. Contents of the invention [0005] In order to solve the above problems, the present invention provides a kind of ultraviolet odor-cleaning paint that adopts macromolecules, no aldehyde, no peculiar smell, and no benzene series. The specific technical scheme is as follows: [0006] An ultraviolet odor-cleaning paint, which is made ...
