AI Technical Summary

Problems solved by technology

Using 1 and 2 methods will lead to waste of production cost and time. Using the third method to use unsaturated polyester paint, although the surface hardness of unsaturated polyester paint is higher, but the use of unsaturated polyester paint There are higher requirements. After the paint is added with blue water cobalt isozincate and white water methyl ethyl ketone peroxide, it can be used for only 20 minutes. If it exceeds this time, the paint will be gelled and scrapped. Caution can lead to waste and quality issues
In terms of use and requirements, it is extremely difficult to achieve a good level

Abstract

The invention provides a wear-resistant polyurethane glossy black finishing paint and a preparation method thereof; the finishing paint is composed of a component A, a component B and a component C; the three components are prepared and packaged respectively; therefore, the storage time is long; and chemical change is difficultly caused. When the wear-resistant polyurethane glossy black finishing paint is used, the solidification time can be adjusted by adjusting the proportion of the three components; and therefore, the wear-resistant polyurethane glossy black finishing paint has higher practicability and production adaptive capacity.

Description

technical field [0001] The invention relates to a high wear-resistant black finish paint, in particular to a wear-resistant polyurethane bright black finish paint. Background technique [0002] Black and white furniture is widely used in daily furniture products due to its eternal tone, such as living room board-type audio-visual furniture with black and white matching, speakers, bedroom furniture, etc., all of which use black and white light as the main products. The surface of polyurethane gloss paint has poor abrasion resistance and scratch resistance, while white paint and other colors of gloss paint are light in color, even if the surface paint film is scratched, it is difficult to see the scratch due to the refraction of light. Therefore, this type of products often use polyurethane paint to meet the requirements, but the products produced by black varnish paint are easy to be scratched by cloth during the process of producing and packaging dust on the products, and th...
