Abstract

The invention discloses special osmosis primer paint for solid wood furniture. The special osmosis primer paint comprises main paint and a curing agent. The main paint is prepared from, by weight, 40-60 parts of highly-wetting alkyd resin, 0.4-0.7 part of a polysiloxane antifoaming agent, 0.3-1.8 parts of a substrate wetting agent, 0.02-0.2 part of an organic tin drier and 40-50 parts of a first solvent. The curing agent is prepared from, by weight, 40-45 parts of hexamethylene diisocyanate, 13-18 parts of toluene diisocynate tripolymer and 39-44 parts of a second solvent. After the special osmosis primer paint for the solid wood furniture is painted on solid oak wood base materials and cured, the primer paint is subjected to thermal cycling in a thermal cycling machine for 40 times, wherein each-time thermal cycling refers to keeping at 80DEG C for 4h and at -20DEG C for 4h, and consequently paint defects such as peeling and mildewing are avoided.

Description

technical field [0001] The invention relates to a paint coating, in particular to a special penetrating primer for solid wood furniture. Background technique [0002] Wood is a structural material widely used in the furniture manufacturing and construction industries. In order to beautify wood products and prolong their service life, they need to be protected. At the same time, unlike other structural materials, wood has greater water content and water absorption than other materials; and the paint will also penetrate into the wood, so these will have an adverse effect on the coating. [0003] The invention patent with the authorization number CN101817906 uses acrylic monomers containing various polar groups as raw materials and adds various additives to prepare a water-based acrylic wood sealing coating. This coating has certain wettability to wood , and the latex particles can penetrate into the wood fiber conduit to form a film, which can prevent the moisture in the wat...
