Embodiment 1

[0016] Example 1: Weigh the following raw materials in weight percentage: 70KG of reactive acrylate prepolymer, 15KG of reactive acrylate monomer, 3KG of photoinitiator, 7KG of pigment, and 5KG of auxiliary agent. Prepare by the following method: (1) Pre-prepare the acrylate monomer and silicon-modified acrylate or / and fluorine-modified acrylate or / and silicon-fluorine-modified acrylate and acrylate according to the mass ratio in the total system. The polymer is mixed, heated to 50~60℃, and stirred evenly; (2) Then, in step (1), add part of the additives of the system according to the proportion of the total system, and stir fully until it is completely dissolved; (3) Then the total system Fillers, pigments, etc. are added to the system of step (2) according to the proportions, stirred, dispersed, and wetted; (4) Use three-roller or ball mill or sand mill and other grinding equipment to fully grind the result of (3). Until it reaches the standard; (5) Add initiator and other ad...

Embodiment 2

[0018] Example 2: Weigh 30KG of reactive acrylate prepolymer, 50KG of reactive acrylate monomer, 8KG of photoinitiator, 7KG of filler, and 5KG of auxiliary agent. Prepare according to the following method: (1) Mix the acrylate monomer in the system with silicon-modified acrylate or fluorine-modified acrylate or silicon-fluorine-modified acrylate and acrylate prepolymer according to the mass ratio in the total system , Heat up to 50~60℃, stir evenly; (2) then add part of the additives of the system according to the proportion of the total system in step (1), stir fully until completely dissolved; (3) add the fillers of the total system according to the proportions Add to the system of step (2), stir, disperse, wetting, disperse or grind until it reaches the standard; (4) Add initiator and other auxiliary agents according to the proportion in the system to the result of (3), and fully disperse until complete Dissolved and mixed.

Embodiment 3

[0019] Example 3: Weigh 50KG of reactive acrylate prepolymer, 46KG of reactive acrylate monomer, and 4KG of photoinitiator. Prepare according to the following method: (1) Mix the acrylate monomer in the system with silicon-modified acrylate or fluorine-modified acrylate or silicon-fluorine-modified acrylate and acrylate prepolymer according to the mass ratio in the total system , Warm up to 50-60 ℃, stir evenly; (2) then add the initiator to the result of (1) according to the proportion in the system, and fully disperse until completely dissolved, and mix the result.

Abstract

The invention belongs to the field of coatings, relates to a radiation curing silicon fluoride coating and a preparation method and application thereof, and particularly discloses a radiation curing silicon fluoride coating. The coating is prepared from 30-70wt% of reactive acrylate prepolymer, 15-50wt% of reactive acrylate monomer, 3-8wt% of photoinitiator, 0-35wt% of pigment, 0-10wt% of filler and 0-5wt% of additive. Compared with the prior art, the radiation curing silicon fluoride coating has better color and pattern expressive force when carrying out surface treatment on decorative materials, has good antibacterial, anti-pollution, self-cleaning, waterproof and anti-mold properties and better weather resistance, heat resistance and mechanical performance, is wider is application range and can be widely applied to surface treatment, beautifying and protection of indoor and outdoor decoration materials.

Description

Technical field [0001] The invention belongs to the field of coatings, and particularly relates to radiation curing silicon-fluorine coatings and preparation methods and applications thereof. Background technique [0002] The application of radiation curing technology in the coatings industry began in the early 1960s when Bayer in Germany successfully developed light-curing wood coatings. Now UV technology has been developed by leaps and bounds, especially with its excellent surface properties, high curing speed, low pollution, energy saving, etc., it has become an environmentally friendly technology, and its application ranges from the original floor coatings and wood coatings to the current inks and plastics. Coatings, motorcycle coatings, automotive coatings, and more advanced optical fibers / optical cables, optical discs, solar films, flat-panel display functional films, and mummy production in archaeology. [0003] In China, radiation-curable coatings can be regarded as a new ...
