Automatically sprayed ultraviolet curing paint and preparation method thereof

Abstract

The invention relates to an ultraviolet curing paint, and concretely relates to an automatically sprayed ultraviolet curing paint and a preparation method thereof. A disadvantage of present ultraviolet curing paints is that: the curing process is completed in several seconds, and the large contraction makes the formation of the thick coating to be impossible, so the usage of the paints in the anticorrosion field is restricted. The ultraviolet curing paint comprises the following substances, by weight, 100 parts of an oligomer, 20-50 parts of a monomer, 10-30 parts of a coupling agent, 2-10 parts of an acid anhydride, 1-2 parts of a mixed assistant, 10-30 parts of nanometer silica, 3-10 parts of a photoinitiator, 80-200 parts of a solvent and 100-200 parts of a propellent. The ultraviolet curing paint of the invention, which allows a technical problem of ultraviolet curing paints for the equipment anticorrosion to be solved, has the advantages of good anticorrosion effect, convenient construction, no need of compressed air, realization of the automatic spray, simple preparation method, safety, no pollution, fast curing speed, high production efficiency, high film quality, and excellent coating performance.

Description

technical field

[0001] The invention relates to an ultraviolet light curing paint, in particular to an ultraviolet light curing automatic spray paint and a preparation method thereof. Background technique

[0002] Since its invention in 1947, UV-curable coatings have been widely used in various fields, such as paper, wood, plastics, metals, optical discs, optical fibers, electronic communications, sporting goods, automobiles, architectural coatings, packaging materials, etc. Applications. The development speed of my country's UV-curable coating technology is increasing at a rate of 20%-30% every year, and the application of UV-curable coatings in various fields is becoming more and more extensive.

[0003] UV-curable coatings have many advantages that other coatings cannot match, which are shown in: 1. Energy saving and high energy utilization rate; 2. No solvent emission, safe and pollution-free; 3. Fast curing speed and high production efficiency; 4. Can be painted 5. Hi...
