Embodiment 1

[0016] This embodiment discloses a radiation-cured wire enamel, the components of which are: 40 parts of modified epoxy acrylate, 60 parts of acrylic monomer, 3 parts of photoinitiator, and 0.1 part of defoamer.

[0017] This embodiment also discloses the preparation method of the above-mentioned radiation-cured wire enamel, the steps of which are:

[0018] Step 1: Add 40 parts of modified epoxy acrylate and 50 parts of acrylic acid monomer into the reaction kettle at room temperature, and stir until uniform to obtain a semi-finished product A;

[0019] The second step is to add 3 parts of photoinitiator and 0.1 part of defoamer to the semi-finished product A, and fully stir until uniform to obtain the semi-finished product B;

[0020] The third step, according to the viscosity of the desired product, add 10 parts of acrylic acid monomer to the semi-finished product B, and after fully stirring, the above-mentioned radiation-curable wire enamel is obtained, which is put into a ...

Embodiment 2

[0023] This embodiment discloses a radiation-curable wire enamel, the components of which are: 70 parts of polyester acrylate, 45 parts of acrylic monomer, 8 parts of photoinitiator, and 0.3 part of dispersant.

[0024] This embodiment also discloses a preparation method of the above radiation-cured wire enamel, the steps of which are:

[0025] Step 1: Add 70 parts of polyester acrylate and 20 parts of acrylic acid monomer into the reaction kettle at room temperature, stir well until uniform, and obtain semi-finished product A;

[0026] The second step is to add 8 parts of photoinitiator and 0.3 parts of dispersant to the semi-finished product A, and fully stir until uniform to obtain the semi-finished product B;

[0027] The third step, according to the viscosity of the desired product, add 25 parts of acrylic acid monomer to the semi-finished product B, and after fully stirring, the above-mentioned radiation curing wire enamelled varnish is obtained, which is put into a ligh...

Embodiment 3

[0029] The difference between this example and Example 1 is that the modified epoxy acrylate is replaced by acrylated polyacrylic resin, and other components and preparation steps are the same as in Example 1.

Abstract

The invention provides radiation-cured wire coating enamel. The radiation-cured wire coating enamel is characterized by comprising the components are as follows: 40-70 parts of acrylate, 30-60 parts of acrylic monomers, 3-8 parts of an initiator, and 0.1-0.3 part of auxiliaries. The invention further provides a preparation method of the radiation-cured wire coating enamel which adopts a radiation curing technology (the radiation curing technology refers to a process of forming a solid-state product from a liquid-state oligomer through cross-linking polymerization under the action of light or high-energy rays), and has higher curing speed, and does not produce harmful substances in preparation and application processes. And therefore, compared with the existing wire coating enamel and the preparation process thereof, the radiation-cured wire coating enamel has the advantages of being quick in curing speed, less in pollution, energy-saving, and the like, and is an environment-friendly green material.

Description

technical field [0001] The invention relates to a radiation curing wire enamel and a preparation method thereof. Background technique [0002] Enameled wire enamel is a kind of coating that can make a good insulating layer between the wires in the winding. It is mainly used for the outer layer of bare copper wires, alloy wires and glass wires of various wire diameters to improve and stabilize the performance of enameled wires. Can meet heat resistance, impact resistance, oil resistance and other requirements. There are many types of wire enamel, which can be roughly divided into low-end varnish for general use, high-end varnish for high temperature resistance and special purpose, but no matter what kind of wire enamel, it needs higher temperature and longer time in the process of preparation and application , and will produce harmful substances to the environment and human body. Contents of the invention [0003] The object of the present invention is to provide a wire e...
