Abstract

The present invention is one kind of ultraviolet cured antiwear crystal whisker paint and its preparation process, and belongs to the field of light cured paint technology. The ultraviolet cured paint has crystal whisker filled to raise the antiwear performance, and consists of mainly photosensitive oligomer, active diluent, photoinitiator, crystal whisker, stuffing and assistant. It may be applied onto the surface of timber, high density board, metal, glass or ceramic to form coating with excellent performance, including high toughness and high antiwear property. In addition, the paint has no organic solvent and is environment friendly and convenient in use.

Description

technical field [0001] A whisker wear-resistant ultraviolet light-cured coating and a preparation method thereof relate to a wear-resistant coating that can be used on the surfaces of wood, density boards, metals, glass and ceramics, and belong to the technical field of light-cured coating composite materials. Background technique [0002] Ultraviolet (UV) curing coating is a high-tech green environment-friendly coating with no pollution, resource saving, low energy consumption, safety and reliability, and its social and environmental benefits are huge; As a new growth point in the world, countries all over the world are investing heavily in research and development. Today, at the time when my country is vigorously advocating the construction of a sustainable development and conservation-oriented society due to the lack of energy and resources in our country, the promotion and application of UV-curable coatings is of great significance. In 2005, the output of UV curable coa...
