Description
Technical field
The present invention relates to a kind of preparation method of two component polyurethane woodenware light black flour paint, particularly relate to a kind of environmental protection without the low clean taste type scratch resistance two component polyurethane woodenware light black flour paint of benzene.
Background technology
Along with the raising of people's material and cultural life, human consumer requires also more and more higher to the painting effect of furniture, thus has driven the quick growth of domestic woodwork coating.The painting effect of furniture surface will directly affect the selection of human consumer to furniture, and on furniture Coating Market, light wood lacquer also occupies the suitable market share.The requirement of wood lacquer market to painting huge is now more and more higher, dragon its be that woodenware urethane (PU) paints excellent combination property, human consumer uses extensively, but product exists many weak points, as turned white, bubbling, delamination, not scratch resistance, heat rash appears, ghost, impression of the hand not easily disappear.These problems puzzlement producer and engineering technical personnel, some problem fails to solve even for a long time.Develop a kind of resistance to marring high-grade urethane light wood lacquer necessary to the demand meeting market.Along with day by day strict to the attention of environmental protection and various countries' environmental regulation of people, the manufacturer of coating and coating user particularly pay attention to goods smell after the environmental requirement of coating, organic solvent and application.
In suite room furniture field of coating, a difficult problem of puzzlement industry is that furniture is delivered to when installing in terminal client man and reflected that smell is large, and pungent unpleasant, many customer requirements are returned goods or exchanged goods.In the coating process of furniture, after the abnormal and application of the smell of working-yard, furniture smell is two kinds of different states.The former be different workmen to the sensitivity of different organic solvents because different personnel cause working-yard smell to be complained to the odor type of different solvents and irritating smell sensory difference, this just can be dealt with problems by the different thinner of apolegamy; The latter is uncomfortable property smell the having the greatest impact to client that after application, dried coating film is residual after 48 hours, therefore develops a kind of necessary to the demand meeting market without the low clean taste type scratch resistance two component polyurethane light wood lacquer of benzene.
Summary of the invention
The present invention select hydroxyl value > 120mgKOH/g without the low clean taste type scratch resistance Synolac of benzene, this resin contains rigid molecular structure, have that scratch resistance, hardness are high, the feature such as quick-drying, wear-resisting, color inhibition, containing more primary hydroxyl in resin structure, sterically hindered little, be conducive to being cross-linked into reticulated structure with NCO in solidifying agent, improve film performance; And second-order transition temperature is high, be conducive to solvent release, accelerate the convection current of film internal solvent and the increase of top layer viscosity, reduce smell; Simultaneously this resin without benzene without ketone, good leveling property, thus improve the gloss of film, transparency, fullness ratio and anti-scratch performance.
The present invention selects aromatic free high hydroxyl value Hydroxylated acrylic resin, can improve the gloss of paint film, fullness ratio, hardness, anti scuffing performance, improve the performance such as rate of drying and sag prevention simultaneously.
Modified siloxane type defoamer selected by defoamer of the present invention, effectively can eliminate bubble and can not produce again surface atomizing and shrinkage cavity phenomenon.
The present invention selects chelate modified flow agent or silicon-oxygen polymer flow agent, unstable bubble, can provide excellent levelling property again can froth breaking.Due to the special role of titanic acid ester group, greatly improve the long wave levelling of paint film, eliminate dry rear appearance " large wave " phenomenon of paint film, make paint film reach mirror effect.Because titanic acid ester has close organic phase, close inorganic phase specific groups, can wets out pigments and ground quickly and effectively, improve wettability, the defoaming of paint film, thus make paint film have excellent planeness and dry after not easily produce advantages such as sinking.And silicon-oxygen polymer flow agent, can reduce the surface tension of paint film, antiskid is felt well good hand touch, improves resistance to marring, does not affect recoatability and ply adhesion, without ghost.
