Description

Technical field:

[0001] The invention belongs to the field of chemical industry, and relates to a solvent-type matte wood varnish and a preparation method thereof, in particular to a solvent-type matte wood varnish with high transparency and high fullness and a preparation method thereof. This high-clarity, high-volume, solvent-based matt wood lacquer is primarily intended for painting on wood. technical background:

[0002] Before the 1990s, the domestic paint and coating technology was not perfect and comprehensive, and the technical force was not strong enough. What were coated on the woodenware were some common solvent-based woodware lacquers, such as the solvent-based matte woodware lacquer disclosed in patent CN 102977750 A It has high wear resistance and high hardness, but the transparency and fullness of the paint film are not enough, and the satisfactory coating effect cannot be achieved. With the continuous development of society, people's living standards continu...
