Special substrate sealing agent for dyed veneers and preparation method thereof

Abstract

The invention discloses a special substrate sealing agent for dyed veneers. The special substrate sealing agent comprises a main agent, a curing agent and a diluent. The main agent is composed of thefollowing raw materials in parts by weight: 50-70 parts of acrylic resin, 1 to 3 parts of methyl isobutyl ketone, 5 to 12 parts of butyl acetate, 0.1 to 1 part of a titanate coupling agent, 1-2 partsof barium sulfate, 0.1 to 0.5 part of a wetting agent, 0.3 to 1 part of a leveling agent, 0.3 to 1 part of an antifoaming agent, 2-4 parts of a light stabilizer, 0.4 to 1 part of a drier, 7 to 10 parts of butyl acetate and 15 to 20 parts of ethyl acetate. The curing agent is composed of the following raw materials in parts by weight: 60-70 parts of butyl acetate and 30 to 40 parts of an HDI tripolymer. The diluent is composed of the following raw materials in parts by weight: 40-50 parts of butyl acetate and 50-60 parts of propylene glycol methyl ether acetate. The special substrate sealing agent for the dyed veneers has extremely strong sealing property on grease in wood, and can effectively prevent the grease of the dyed veneers from seeping out.

Description

Technical field [0001] The invention relates to the technical field of chemical coating manufacturing, in particular to a special substrate sealing agent for dyeing veneer and a preparation method thereof. Background technique [0002] Dyed veneer can change the color without changing the texture of natural veneer. At the same time, the diversification of colors enriches designers' color imagination space, enhances the use value of veneer itself, and adds a lot of color to the living environment. Dyeing highlights the texture of the wood and the natural characteristics of its three-dimensional features such as shadow, grenade, and eyes. The greatest value of wood dyeing is manifested in its unlimited creative potential. In the trend change year after year, in the simple and endless creative interpretation like nature, it can create rich and usable colors and colors. Color, so the special sealant for dyed veneer has received more attention. However, the sealant for dyed veneer cu...

Problems solved by technology

The greatest value of wood staining lies in its unlimited creative potential. It can create rich and available colors and Therefore, the special sealant for dyed veneer has received more attention. However, the sealant for dyed veneer on the market is poor in sealability, which makes the wood oil easy to seep out, resulting in inconsistent oxidation on the surface of dyed veneer, resulting in problems such as discoloration and fading.
