Description
Technical field
The present invention relates to woodcare paint field, a kind of universal aqueous wooden ware colored varnish in bottom surface and its preparation side are specifically disclosed
Method.
Background technology
In China Furniture Industry, outlet furniture occupies very big proportion, and the U.S., European Union and Japan have all put into effect limitation
With the relevant laws and regulations for prohibitting the use of solvent wood coatings, solvent based coating contains substantial amounts of VOC (VOC)
And formaldehyde, VOC is VOC (Total Volatile Organic Compounds) english abbreviation.VOC
Main component have：Hydro carbons, halogenated hydrocarbons, oxygen hydrocarbon and nitrogen hydrocarbon, it includes：It is benzene homologues, organic chloride, freon series, organic
Ketone, amine, alcohol, ether, ester, acid and oil hydrocarbon compound etc..Indoors in decoration process, VOC is essentially from paint.VOC has
Penetrating odor, and some compounds have genotoxicity.It is generally believed that VOC can cause immunity of organism off-leveling, influence
, there is the subjective symptoms such as dizzy, headache, drowsiness, powerless, uncomfortable in chest in central nervous system function；Digestive system is can also affect on, is gone out
Now poor appetite, nausea etc., when serious can liver injury and hemopoietic system, there is allergy etc..Formaldehyde, which is that one kind is colourless, to be had
Evil gas, Long Term Contact may cause nasal cavity, oral cavity, throat, skin and alimentary tract cancer.And the formaldehyde main source of premises
In ornament materials such as all kinds of planks, furniture and paint.
Solvent based coating will be substituted gradually by more environmentally-friendly water paint.Woodcare paint as furniture industry important original
Auxiliary material, its quality directly affects the low-carbon environment-friendly level of furniture industry.
Current aqueous woodware paint is less with water-base resin, and quality is also uneven；Auxiliary agent with paint, its is alternative
Kind is also few.Based on some of the above reason, the performance of aqueous woodware paint still has certain gap compared with solvent based coating, it

Embodiment
The present invention is expanded on further with reference to embodiment.It should be understood that embodiment is merely to illustrate the present invention, and it is unrestricted
The scope of the present invention.
Aqueous aliphatic polyurethane has excellent permeability and flexibility, the clear high glaze of film forming.Use aqueous aliphatic
The aqueous polyurethane paint good combination property that polyurethane resin can be prepared, intensity is big, and good film-forming property, high glaze, strong adhesive force is wear-resisting
Property is excellent, and shock resistance is good, and all indexs meet or exceed the national standard of solvent borne polyurethane paint.So as to as solvent
The substitute of type polyurethane paint.Selection section day chemical industry KT200, KT807 or KT600 waterborne polyurethane resin, its nontoxic pure environmental protection,
Without hazardous solvents such as formaldehyde, benzene, to human body fanout free region, VOC content meets International Environmental Protection standard.
Acrylic resin has preferable water resistance, weatherability.Aqueous aliphatic polyurethane and acrylic resin coordinate and made
With acrylic resin being used to improve aqueous polyurethane weatherability and water resistance.The strong point of two kinds of resins is given full play to, so that poly-
The performance of urethane coating be improved significantly.The weight ratio of aqueous aliphatic polyurethane and acrylic resin is (5-25)：(55-
75).It is highly preferred that the weight ratio of aqueous aliphatic polyurethane and acrylic resin is (10-20)：(60-70), further preferably
Ground, the weight ratio of aqueous aliphatic polyurethane and acrylic resin is (14-17)：(64-68).
The factor of influence resin MFT is a lot, and most important is exactly its chemical composition and polymer architecture.
Its chemical composition determines its glass transition temperature (Tg), and the Tg is to influence the main factor of MFT (MFT),
Under normal circumstances, MFT is less than the Tg of phase emergencing copolymer.The film-forming temperature of acrylic resin is 42 DEG C or so in the present invention, aqueous
The Tg of polyurethane resin is relatively low, and the MFT of waterborne polyurethane resin is than relatively low.In addition, aqueous aliphatic polyurethane and propylene
Acid resin is with the use of causing the Tg of emulsion particle also to change in gradient, and the coating of formation has wider temperature transfer interval,
So that the MFT reductions of aqueous polyurethane dispersion.
Aqueous woodware paint for contact angle is therebetween zero in the condition of the abundant levelling of substrate surface, i.e. the surface of base material
The surface of energy and aqueous woodware paint can approximately equal.For aqueous coating system, in some base materials with low-surface-energy
On the problem of very likely soak.And by adding a small amount of wetting agent, just can reach reduction paint film coated surface tension force
Purpose, makes paint become prone to coating.A kind of effect of wetting agent depends on will not occurring some adverse side effects in application process
(such as：Inter-coat adhesion is bad, easily foaming, increases water sensitivity of system etc.).I.e. wetting agent is except can effectively reduce body
The surface tension of system, increases outside to timber wetability and permeability, moreover it is possible to promote the compatibility of defoamer and system, improves interlayer
Adhesive force.
The species and consumption of wetting agent should be according to the surface tension, the interfacial tension of base material, froth breaking of aqueous wooden ware coating resins
The factors such as the species and consumption of agent are determined.And because aqueous woodware paint mainly uses brush application.This requires wetting agent to exist
Also wetting and mobile performance can be improved in high dynamic work progress, surface tension is promptly reduced, it is possible to suppress foam, promoted
Deaeration.Using aqueous polyurethane resin emulsion as the aqueous woodware paint of base-material, the present invention selects organic-silicon-modified wetting agent and propylene
The modified wetting agent of acid, it is preferable that select the high TEGO270 wetting agents of enlightening, can reach reduction system surface tension, promote deaeration
Effect.The addition of aqueous wetting agent must be moderate, and excessive substrate wetting agents can form micella, makes the defoamer of addition and has
It is partly into wherein, so as to reduce defoaming effect.One is preferred the addition of aqueous wetting agent with 0.2-3%, and is needed
It is slowly added in the case of stirring.
Effect of the defoamer in aqueous woodware paint be mainly manifested in two sides and：One is to ensure that production can be smoothed out；Two
It is to ensure not produce foam during construction, assigns good paint film.Defoamer improper use in woodcare paint can produce side effect, remove
Cause outside shrinkage cavity, can also cause gloss of film to decline, adhesive force and water resistance reduction.Note the examination of combination property, note
The selection of defoamer kind and control its addition.Defoamer is selected using following methods.The aqueous froth breaking that the present invention is selected
Agent is that organosilicon, mineral oil or polyethers are modified any one in defoamer, it is preferable that it is high that aqueous defoamer is selected from model enlightening
TEGO902W, its addition is advisable with 0.2-3%, it is further preferred that the addition of aqueous defoamer is 0.2-0.8%.
The present invention by add cataloid improve the woodenware colored varnish hardness, cataloid be using water for divide
The colloidal solution of the poly- metasilicic acid of inorganic polymer of dispersion media.Its silicon dioxide granule is more with spherical single or multiple coalescences point
Dissipate, drying process can form firm Si-O keys with the continuous evaporation of moisture between silicon dioxide granule, its particle is also constantly
Increase is finally stably dispersed in resin, and the addition of cataloid need to be controlled within the specific limits, and its addition is with 3-
8% is advisable.The present invention further improves the hardness of the woodenware colored varnish, liquid potassium silicate and colloid two by adding liquid potassium silicate
Silica with the use of causing the hardness of the woodenware colored varnish to be optimal, the addition of liquid potassium silicate and cataloid
The weight of addition is than control at (0.5-1)：(3-8).
