Description
Technical field
The present invention relates to a kind of preparation methods of bi-component polyurethane ester wood lacquer, more particularly to a kind of translucent shallow maple color
Forge raw ordor removing type scratch resistance two component polyurethane lacquer as woodenware finish of receiving.
Background technology
With the raising of people's material and cultural life, consumer is also higher and higher to the painting effect requirement of furniture,
To drive the rapid growth of domestic woodwork coating.American and European style furniture occupies larger market part on furniture Coating Market
Volume, domestic furniture industry all use mostly color essence (a kind of premetallized dye, such dyestuff exist such as heavy metal severely exceed,
It is poor containing morbid substance, temperature tolerance, light resistance, resistance to migration, it is commonly called as glaze) wood grain wiping color and Lacquer finish colouring matter are carried out, it wipes
The resin of color is mostly common alkyd resin and linseed oil, and furniture still has peculiar smell in some time after application；It is current huge
Requirement of the woodcare paint market to painting it is higher and higher, dragon its be woodenware polyurethane (PU) paint excellent combination property, consumption
Person uses extensively, but product such as whitens, blisters, delamination, scratch resistance, ghost, impression of the hand are not easy to disappear there are many shortcomings
Deng.
Translucent shallow maple color forges raw toner pigment of receiving with excellent weatherability, light resistance, ultraviolet-absorbing, transparent
Degree height, elegant, nontoxic, the excellent chemical stability of color, excellent alkaline-resisting, acid resistance.It is translucent to forge raw toner of receiving with very
Good temperature tolerance is 300 DEG C；And forge raw toner of receiving without bleeding, it is resistance to migrate with it is insoluble.
Ultraviolet light be destroy wooden arch-criminal, and forge it is raw receive toner pigment can strong ultraviolet radiation-absorbing, to protect
It is wooden, and Wood Energy is made to play coloring effect, and wooden holding native texture can be made, color is soft；And translucent forge Sheng Nase
When powder pigment is used in mixed way with organic transparent pigment, the color of pigment can be not only enriched, improves chroma, and can significantly improve
Organic transparent pigment usual weatherability, deficiency of temperature tolerance difference when being used alone, keep wood grain clear when being coloured for wood furniture
Thoroughly, furniture is made to seem elegant noble, natural and unaffected.
In suite room furniture field of coating, a problem for perplexing industry be furniture be sent in terminal client man install when it is anti-
It is big to reflect smell, is pungent unpleasant, many customer requirements return goods or exchange goods.In the coating process of furniture, the smell of construction site is different
Often and after application furniture smell is two different states.The former is different sensitivity of the construction personnel to different organic solvents
Because different personnel cause construction site smell to be complained the odor type and penetrating odor sensory difference of different solvents, this passes through degree
Matching different diluents can solve the problems, such as；The latter is dried coating film remaining discomfort smell pair after 48 hours after application
The influence of client is maximum, therefore a kind of American Style Furniture of exploitation meets client with ordor removing type scratch-resistant polyurethane woodenware Lacquer finish finishing coat
Demand it is necessary.
Invention content
The present invention selects the ordor removing type scratch resistance alkyd resin of hydroxyl value ＞ 120mgKOH/g, the resin to contain rigid molecule knot
Structure has the characteristics that scratch resistance, hardness height, quick-drying, wear-resisting, color inhibition, contains more primary hydroxyl, space bit in resin structure
It hinders small, is conducive to be cross-linked into reticular structure with NCO in curing agent, improves film performance；And glass transition temperature is high, is conducive to solvent
Release accelerates the increase of the convection current and surface layer viscosity of film internal solvent, accelerates the release of solvent；Cause flatting silica more simultaneously
Ground is detained, and dosage is few, and extinction performance is good, good leveling property, to improve gloss, transparency, richness and the anti-scratch performance of film；
And the resin, without vegetable oil (aliphatic acid), benzene-free ketone-free, therefore toxicity is low, and manufactured woodcare paint was in coating, drying 48 hours
Film reaches ordor removing effect afterwards.
Antifoaming agent of the present invention selects modified siloxane type antifoaming agent, bubble can be effectively eliminated and not will produce surface atomizing and
Shrinkage cavity phenomenon.
The present invention selects chelate modified levelling agent or silicon-oxygen polymer levelling agent, not foam stabilizing that can provide excellent levelling
Property again can defoam.Due to the special role of titanate esters group, the long wave levelling of paint film is substantially improved, eliminates after paint film is done and occurs
" big wave " phenomenon, makes paint film reach mirror effect.It, can be fast since titanate esters have organic-philic phase, close inorganic phase specific groups
Speed effectively soaks pigment and ground, improves wetability, the defoaming of paint film, to make paint film have excellent flatness and do
After be not likely to produce the advantages that sagging.And silicon-oxygen polymer levelling agent, the surface tension of paint film can be reduced, antiskid is felt well good hand touch, is carried
High scratch resistance does not influence recoatability and ply adhesion, no ghost.
In order to solve the problems, such as that techniques as described above, the present invention take following technical scheme：The present invention relates to a kind of semi-transparent
Bright shallow maple color forge it is raw receive ordor removing type polyurethane woodcare paint, be grouped as by lacquer type organic coating first component and curing agent second group, the first and second components
