Problems solved by technology

[0008] Zou Yingquan’s paper (Li Wei, Zou Yingquan, Information Recording Materials, 2011,12(5), 38) summarizes the application research of fluorine-containing monomers or fluorine-containing resins in photocurable compositions. The higher the content, the worse the compatibility with other components, and the corresponding increase in formula cost
Because of the difficulty of preparation, these fluorine-containing monomers or resins are rarely commercialized

Embodiment 1

[0026] Example 1 Fluororesin FR01 with photoinitiator group

[0027] Under nitrogen protection, put 400g fluororesin (model SRF-350, resin solid content 60%, hydroxyl value 50mg / g, produced by Beijing Huatong Ruichi Technology Co., Ltd.), 48.4g o-carboxydiphenyl Methanone, 2g p-toluenesulfonic acid, and 400g toluene were heated to 114°C and refluxed for 15 hours. After the reaction was completed, the reaction solution was precipitated to obtain 290 g of fluororesin FR01 with photoinitiator groups. Add methyl ethyl ketone equal to the mass of the product to dissolve it, and obtain the methyl ethyl ketone solution of the target product FR01.

Embodiment 2

[0028] Example 2 Fluororesin FR02 with photoinitiator group

[0029] Using the synthesis method of Example 1, 48.4 g of o-carboxybenzophenone was replaced with 54.87 g of 4-carboxymethoxybenzophenone to obtain a methyl ethyl ketone solution of the target product FR02.

Embodiment 3

[0031] 1. Preparation of the composition:

[0032] Add each component according to the composition shown in Table 1 and the mass parts thereof, stir to make it dissolve uniformly, obtain experimental example 1, experimental example 2, experimental example 3, comparative example 1, comparative example 2 and comparative example 3 a total of six group composition.

[0033] Table 1

[0034]

[0035] 2. Paint film curing process

[0036] The above compositions were coated on a white PC plate with a 25 μm wire bar, baked at 60°C for 10 minutes, and then passed through a 600mW / cm 2 25S of ultraviolet light irradiation (except surface drying test and gel conversion rate test) to obtain a paint film with a thickness of 10 μm. The paint film was tested as follows, and the results are shown in Table 2.

Abstract

Fluororesin having a photoinitiator group, preparation thereof and applications of the fluororesin are provided. The photoinitiator group is in a side chain of the fluororesin having the photoinitiator group. A preparing method includes esterifying hydroxy-containing fluororesin and a carboxyl-containing photoinitiator. A photocuring composition is also provided and comprises 0.1-5% of the fluororesin having the photoinitiator group, 87-98.9% of reactive resin or an active monomer and 1-8% of a photoinitiator. Photocuring paint significantly improving water proofness, oil proofness and fouling resistance is provided.

Description

Technical field: [0001] The invention relates to a functional fluororesin, especially a fluororesin with a photoinitiator group, a preparation method and application thereof. Background technique: [0002] In the field of coatings, weather resistance is one of the important properties of outdoor coatings. At present, the industry mainly modifies coatings by directly adding fluorine materials. Adding fluorine materials to coatings can effectively improve the waterproof, oil, and antifouling properties of coatings. , weather resistance and chemical corrosion resistance. Fluorocarbon paint is one of the varieties with the best performance in the prior art. [0003] Fluorine-containing materials have been widely used due to their excellent thermal stability, corrosion resistance, low surface tension and other properties. For example, in Chinese patent CN103059316A, fluorine-containing modified polyurethane is introduced into light-curing coatings to enhance the water and stain...
