Description
Technical field
The present invention relates to a kind of preparation method of two component polyurethane woodenware light black flour paint, more particularly to a kind of environmental protection is without the low net taste type scratch resistance of benzene
Two component polyurethane woodenware light black flour paint.
Background technology
With the raising of people's material and cultural life, consumer requires also more and more higher to the painting effect of furniture, so as to drive domestic wood
The rapid growth of device coating.The painting effect of furniture surface will directly affect selection of the consumer to furniture, the light woodenware on furniture Coating Market
Paint also takes up the suitable market share.Requirement more and more higher of the current huge woodcare paint market to painting, imperial its is woodenware polyurethane (PU) paint
Excellent combination property, consumer using extensive, but be present many weak points in product, such as turn white, bubble, delamination, not scratch resistance, rise
Prickly heat, ghost, impression of the hand are difficult disappearance etc..These problems perplex producer and engineers and technicians, and some problems even fail to solve for a long time.Open
Top grade polyurethane light woodcare paint is necessary to meet the demand in market to send out resistance to marring a kind of.The attention to environmental protection and various countries' environmental law with people
Rule it is increasingly strict, product smell is particularly paid attention to the environmental requirement of coating, organic solvent and after application for the manufacturer of coating and coating user.
In suite room furniture field of coating, a problem for perplexing industry is that furniture is sent in terminal client man when installing that reflection smell is big, and it is difficult to be pungent
Hear, many customer requirements are returned goods or exchanged goods.In the coating process of furniture, the smell of job site is abnormal and application after furniture smell be two kinds not
Same state.The former be different workmens to the sensitivity of different organic solvents because different personnel are to the odor type and excitant of different solvents
Sense of smell difference causes job site smell to be complained, and this just can solve problem by matching different diluents；The latter is that film is done after application
Influence of the discomfort smell remained after dry 48 hours to client is maximum, therefore exploitation one kind is without the low net taste type scratch resistance two component polyurethane of benzene
Light woodcare paint is necessary to meet the demand in market.
The content of the invention
From hydroxyl value ＞ 120mgKOH/g without the low net taste type scratch resistance alkyd resin of benzene, the resin contains rigid molecular structure, has the present invention
Scratch resistance, hardness are high, quick-drying, wear-resisting, color inhibition the features such as, more primary hydroxyl is contained in resin structure, steric hindrance is small, has
Network structure is cross-linked into beneficial to NCO in curing agent, film performance is improved；And glass transition temperature is high, be conducive to solvent to discharge, accelerate to apply
The convection current of film internal solvent and the increase of top layer viscosity, reduce smell；While the resin benzene-free ketone-free, good leveling property, so as to improve film
Gloss, transparency, richness and anti-scratch performance.
The present invention selects aromatic free high hydroxyl value Hydroxylated acrylic resin, can improve the gloss of paint film, richness, hardness, scratch resistance energy,
Improve the performances such as rate of drying and resist sagging simultaneously.
Defoamer of the present invention selects modified siloxane type defoamer, and can effectively eliminate bubble will not produce surface atomizing and shrinkage cavity phenomenon again.
The present invention selects chelate modified levelling agent or silicon-oxygen polymer levelling agent, and not foam stabilizing can provide excellent levelability energy froth breaking again.Due to
The special role of titanate esters group, substantially improves the long wave levelling of paint film, eliminates after paint film is done and " big wave " phenomenon occurs, reaches paint film
Mirror effect.Because titanate esters have close organic phase, close inorganic phase specific groups, pigment and ground can be quickly and effectively soaked, improve paint film
Wetability, defoaming so that paint film have the advantages that excellent flatness and it is dry after be not likely to produce it is sagging.And silicon-oxygen polymer levelling agent,
The surface tension of paint film can be reduced, antiskid is felt well good hand touch, improves resistance to marring, recoatability and ply adhesion is not influenceed, without ghost.
In order to solve the problems, such as techniques as described above, the present invention takes following technical scheme：
One kind is made up of, the first and second components without the low net taste type scratch-resistant polyurethane woodenware light black flour paint of benzene lacquer type organic coating first component and curing agent second component
