Description
Technical field
The present invention relates to a kind of preparation method of bi-component polyurethane ester wood lacquer, particularly relate to a kind of semitransparent majestik red raw sienna clean taste type scratch resistance two component polyurethane lacquer as woodenware finish.
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.On furniture Coating Market, American and European style furniture occupies the larger market share, domestic furniture industry all uses look essence (a kind of metallized dye mostly, there is such as heavy metal severe overweight, poor containing morbid substance, temperature tolerance, light permanency, resistance to migration in this type of dyestuff, be commonly called as Ge Lisi) carry out wood grain wiping look and Lacquer finish colouring matter, the resin wiping look is mostly common Synolac and oleum lini, and after application, interior furniture still has peculiar smell for a long time; 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, and as turned white, bubbling, delamination, not scratch resistance, ghost, impression of the hand not easily disappear.
Semitransparent majestik red raw sienna toner pigment has excellent weathering resistance, photostabilization, ultraviolet-absorbing, transparency is high, color is elegant, nontoxic, excellent chemical stability, excellent alkaline-resisting, acid resistance.Semi-transparent open-birth is raw to be received toner to have good temperature tolerance is 300 DEG C; And Sheng Shengna toner is without bleeding, resistance toly to migrate with insoluble.
Ultraviolet destroys wooden arch-criminal, and Sheng Shengna toner pigment energy strong absorption ultraviolet radiation, thus protect wooden, and make Wood Energy play coloring effect, can make again wooden maintenance native texture, color is soft; And semi-transparent open-birth raw receive toner pigment and organic transparent pigment used in combination time, not only can enrich the color of pigment, improve chroma, and the deficiency of usual weathering resistance when organic transparent pigment is used alone, temperature tolerance difference can be improved significantly, make wood grain thoroughly clear time painted for wood furniture, furniture is seemed, and elegance is noble, natural and unaffected.
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 the demand that a kind of American Style Furniture meets client with clean taste type scratch-resistant polyurethane woodenware Lacquer finish finish paint necessary.
Summary of the invention
The present invention selects the clean taste type scratch resistance Synolac of hydroxyl value > 120mgKOH/g, 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, the release of accelerated solvent; Cause flatting silica to be detained more, consumption is few simultaneously, and eliminate optical property is good, good leveling property, thus the gloss of raising film, transparency, fullness ratio and anti-scratch performance; And this resin containing vegetables oil (lipid acid), without benzene without ketone, therefore toxicity is low, the wood lacquer made coating, drying after 48 hours film reach clean taste effect.
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.
In order to solve technical problem recited above, the present invention takes following technical scheme: the present invention relates to a kind of semitransparent majestik red raw sienna clean taste type polyurethane wood lacquer, be made up of resin paint first component and solidifying agent second component, the weight proportion of the first and second components is 1:0.5; Described resin paint first component comprises clean taste type scratch resistance Synolac 40% ~ 60%, flatting silica 0% ~ 6%, dispersion agent 0.1% ~ 1%, highest-ranking imperial concubine's redness slurry 3% ~ 30%, modification flow agent 0.1% ~ 0.5%, defoamer 0.1% ~ 0.5%, anti-settling agent 0.2% ~ 3% and solvent 5% ~ 20%; Described solidifying agent second component comprises TDI-HDI mixed trimer or TDI/TMP affixture 30 ~ 40%, HDI tripolymer 25 ~ 35% and solvent 25 ~ 35%.
Wherein, Synolac selects the clean taste type scratch resistance Synolac of hydroxyl value >=120mgKOH/g, acid number < 10mgKOH/g.
