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.

Abstract

The invention discloses a special substrate sealer for stained veneer, which comprises a main agent, a curing agent and a diluent. The main agent is composed of the following raw materials in parts by weight: acrylic resin: 50-70 parts; methyl isobutyl Ketone: 1-3 parts; Butyl acetate: 5-12 parts; Titanate coupling agent: 0.1-1 part; Barium sulfate: 1-2 parts; Wetting agent: 0.1-0.5 parts; Leveling agent: 0.3 ~1 part; defoamer: 0.3~1 part; light stabilizer: 2~4 parts; drier: 0.4~1 part; butyl acetate: 7~10 parts; ethyl acetate: 15~20 parts; The curing agent is composed of the following raw materials in parts by weight: butyl acetate: 60-70 parts; HDI trimer: 30-40 parts; the thinner is composed of raw materials in the following parts by weight: butyl acetate: 40-40 parts 50 parts: Propylene Glycol Methyl Ether Acetate: 50-60 parts, the special substrate sealant for dyed veneer has a strong sealing ability to the oil in wood, and can effectively prevent the oil of dyed veneer from seeping out.

Description

technical field [0001] The invention relates to the technical field of chemical paint manufacturing, in particular to a special substrate sealer for dyed veneer and a preparation method thereof. Background technique [0002] Dyed veneer can change color without changing the texture of natural veneer. At the same time, the variety of colors enriches the color imagination space of designers, improves the use value of veneer itself, and adds a lot of color to the living environment. Staining accentuates the grain of the wood and its natural character as exhibited by its three-dimensional features ie shadows, pomegranates, eyes etc. 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...
