Problems solved by technology

[0003] With the improvement of people's living standards and aesthetic taste, people's requirements for interior decoration are getting higher and higher. Decorative films are more and more widely used in furniture, home appliances, interior walls of buildings and exterior walls of buildings. The performance requirements for the printing coating of the decorative film are also getting higher and higher. The printing coatings in the prior art generally have poor graphic and text adhesion, unsatisfactory printing clarity, poor scratch resistance, weather resistance, water resistance and water resistance. Poor abrasiveness, comprehensive performance needs to be further improved, and cannot be repaired after damage, resulting in permanent damage to the decorative film

preparation example Construction

[0025] The preparation method of described vinyl polyacrylate film-forming copolymer comprises the steps:

[0026] Step S1: Add 2,2,3,3,3-pentafluoro-2-fluoropropyl acrylate, 2,4-diamino-6-vinyl-S-triazine, (R)-1-((R )-2,2-dimethyl-1,3-dioxolan-4-yl)prop-2-en-1-ol, benzoin ethyl ether mixed, sonicated for 15-20 minutes, then placed in the mold, in Irradiate for 30-40 minutes under ultraviolet light with a wavelength of 220-250nm to obtain a copolymer;

[0027] Step S2: Add the copolymer prepared in step S1 into an organic solvent, then add 3-chloro-2-hydroxypropyl acrylate to it, stir and react at 30-40°C for 4-6 hours, and remove by rotary evaporation solvent to obtain vinyl polyacrylate film-forming copolymers.

[0028] 2,2,3,3,3-pentafluoro-2-fluoropropyl acrylate, 2,4-diamino-6-vinyl-S-triazine, (R)-1-(( R)-2,2-dimethyl-1,3-dioxolan-4-yl)prop-2-en-1-ol, the mass ratio of benzoin ethyl ether is 1:1:(1-3): (0.03-0.05); The mass ratio of copolymer described in step S2, or...

Embodiment 1

[0032]This example provides a decorative film anti-scratch UV printing coating, which is made of the following raw materials in parts by weight: 40 parts of vinyl polyacrylate film-forming copolymer, 3 parts of polyacrylate leveling agent, and ink absorption aid 2 parts of aluminum silicate, 0.3 parts of photoinitiator benzoin ethyl ether, 2 parts of Fmoc-L-arginine (Alloc), 13 parts of heavy calcium carbonate, 1.5 parts of sodium hexametaphosphate, 1 part of defoamer Deqian 3100 , 2 parts of propylene glycol butyl ether, 45 parts of water; the vinyl polyacrylate film-forming copolymer is first passed through 2,2,3,3,3-pentafluoro-2-fluoropropyl acrylate, 2,4- Diamino-6-vinyl-S-triazine, (R)-1-((R)-2,2-dimethyl-1,3-dioxolan-4-yl)prop-2-ene -1-alcohol is prepared into a polymer by copolymerization, and then grafted by 3-chloro-2-hydroxypropyl acrylate; the particle diameter of the inorganic filler is 1200 mesh.

Abstract

The invention relates to a decorative film anti-scratch UV printing coating, which is prepared from the following raw materials by weight: 40-60 parts of a vinyl polyacrylate film-forming copolymer, 1-5 parts of a leveling agent, 2-6 parts of an ink absorption assistant, 0.2-0.4 part of a photoinitiator, 1-3 parts of Fmoc-L-Arginine (Alloc)2, 10-15 parts of inorganic filler, 1-2 parts of a dispersant, 0.5-1.5 parts of a defoamer, 1-3 parts of a film-forming aid, and 40-50 parts of water. The vinyl polyacrylate film-forming copolymer is formed by: firstly subjecting 2, 2, 3, 3, 3-pentafluoro-2-propyl fluoroacrylate, 2, 4-diamino-6-vinyl-S-triazine, and (R)-1-((R)-2, 2-dimethyl-1, 3-dioxolane-4-yl)propyl-2-ene-1-ol to copolymerization reaction to prepare a polymer, and then grafting the polymer with 3-chloro-2-hydroxypropyl acrylate. The decorative film anti-scratch UV printing coating provided by the invention has the characteristics of abundant sources of the preparation raw materials,low price, excellent comprehensive performance, excellent scratch resistance, excellent weather resistance, water resistance and wear resistance, long service life, safe and environment-friendly production and use process.

Description

technical field [0001] The invention relates to the technical field of decorative films, in particular to a scratch-resistant UV printing coating for decorative films. Background technique [0002] With the development of the economy and the progress of the society, a large number of plastic packaging materials or paper packaging materials are used in the outer packaging of household appliances, mobile phones, and cosmetics, and the requirements for surface decoration are getting higher and higher. At present, the surface decoration of plastic packaging materials or paper packaging materials can be decorated by using general-purpose decorative film materials through hot pressing. One of the more important components in the decorative film material is the transfer coating. The coating performance directly affects the decorative effect and service life of the decorative film. Therefore, how to improve the performance of the decorative film transfer coating has become a hot res...
