Problems solved by technology

[0003] PU or NC coatings are two types of wood coatings commonly used at present. PU paints have superior mechanical properties, weather resistance, and solvent resistance. Basically, all board coatings can be used, but PU paints dry slowly, and the paint film is plump and filling. When making open effects, the construction requirements are usually high, such as thinner amount, oil output, spray gun air output, oil craftsman's craftsmanship, etc.; nitro paint is easy to construct, fast drying, and thin film, suitable for open effects, but Relatively poor mechanical properties, weather resistance, and solvent resistance

Abstract

The invention provides a carpentry grain developing lacquer and a preparation method and application thereof. The carpentry grain developing lacquer is characterized by containing main lacquer, a curing agent and a diluting agent. The carpentry grain developing lacquer is a product integrating the excellent workability of nitrocellulose lacquer and the excellent mechanical performance of PU lacquer, and a lacquer film is hard and tough and not likely to be scratched after being dried; besides, the product is resistant to yellowing and good in grain developing effect, and the surface is neat without the sense of swelling.

Description

technical field [0001] The invention relates to a woodware texture paint and a preparation method and a construction method thereof, which are especially suitable for the DIY decoration market to be used for finishing the painting with the texture effect. Background technique [0002] Wood painting can be divided into open and closed processes according to the sealing effect of the paint film after painting. According to the color effect, it can be divided into natural color, transparent color and solid color process. At present, in the DIY decoration market, these two processes are used. For its own characteristics, people will use different coating processes, such as MDF without wood grain, people will use solid color sealing process; black walnut, sapele, cherry and other light-eyed boards, people will use closed natural color or closed Transparent color coating process; people will use solid color open or transparent color open coating process for deep-eye plates such as...
