The present invention comprehensively considered the factors of the various aspects such as the collocation of film forming matter, scintilla water to the performance of paint film and at
It is influenced caused by this.In order to further promote the understanding of spirit for the essence of the present invention, now ingredient mechanism therein is given
It illustrates.
(1) using scintilla aqueous double-component PU as main film forming substance, it is ensured that the excellent weatherability of paint film, ethanol-tolerant
Property, good gloss, adhesive force, hardness etc..
The hydroxyl acrylic emulsion in aqueous double-component PU that the present invention uses is to use scintilla technology with no soap cream
The synthesis of liquid polymerization methods.It specifically gets on very well, present invention utilizes the spatial structures of scintilla water cluster and intermolecular various weak
Interact the synergistic effect of (such as hydrogen bond, Van der Waals force), and the directionality and selectivity of the interaction between scintilla make
Polymer emulsion forms unique three-dimensional structure, so that the aqueous acrylic emulsion for dispersing and synthesizing in scintilla water and city
Comparing with synthesis such as deionized waters on face, membrane formation mechanism is different, using the film forming mechanism of molecular level, with dampening
Evaporation, physicochemical aggregation occurs for the specific functional groups in adjacent polymer, so that water-based microemulsion polymeric system produces
Physical space crosslinking is given birth to, the critical solid content of this physical crosslinking is much lower compared with common micelle, in other words, this
Crosslinking phenomena can occur when water content is higher, more significant to system bring reinforcing effect, extend aqueous plastic paint
Storage time, shorten the drying time of aqueous plastic paint, improve the attachment of the wetting ability and paint film to plastic rubber substrate
Power improves the package ability to pigments and fillers particle, it is possible to reduce the use of related auxiliaries, the paint film for being prepared out also have
There are excellent weatherability, alcohol resistance, flexibility, hardness etc..The hydroxyl acrylic emulsion that emulsifier-free emulsion polymerization mode synthesizes
Ion is stabilized by ionic group, the hydrophilic radical being incorporated on polymer chain, the hydroxy obtained with usual manner

Deng.
(2) scintilla one-component acrylic emulsion is adulterated, is reduced costs, reduces and generates the undesirable appearances phenomenons such as prickly heat.
The one-component acrylic emulsion that the present invention uses is synthesized by being scattered in scintilla water in a manner of homopolymerization or copolymerization
Aqueous acrylic emulsion, compared on the market with synthesis such as deionized waters, this one-component acrylic emulsion is prepared
Aqueous plastic paint there is more excellent resist sagging performance, rate of drying faster etc..Although aqueous double-component PU has excellent
Different weatherability, alcohol resistance, good adhesive force, and be widely used on plastic cement field, the oil instantly turns the environmental protection of water
In tide, aqueous double-component PU potentiality are very big, can be phased out solvent based product.But during practical application, water
Property two-component PU there are also the self shortcomings that overcome of needs.On production cost, the price of aqueous double-component PU is much higher than same
The solvent based product of type, especially isocyanate curing agent are still based on imported product at present, and price is generally 80~90
First per kilogram or so, and the solvent type curing agent of same type only has half or so, this is also to hinder aqueous double-component PU into one
Where walking the resistance promoted, in construction technology, certain aqueous double-component PU are easy to produce prickly heat under high light state, influence table
Face effect, rate of drying are excessively slow.It is easy to receive in single-component water-based acrylic emulsion Costco Wholesale, rate of drying is very fast, still
It is lacking in weatherability, alcohol resistance.And the scintilla one-component acrylic emulsion of doped portion can play good association
Same effect.Confirm through overtesting, the scintilla one-component acrylic emulsion of doped portion, it is hardness, adhesive force, alcohol resistance, resistance to
Time property etc. is in the case that indexs significantly decrease, and lustrous surface is also without notable difference, but the prickly heat under high light state
Etc. bad phenomenons substantially reduce, production cost is greatly reduced, and drying property is also significantly improved.
(3) using scintilla water rather than common deionized water, tap water improve paint as the dissolving medium of water paint
The wetting of film, drying capacity improve the frost resistance and sag resistance of water paint.
Deionized water, distilled water, nature water be not in the form of single molecule existing for, but by several water
Molecule is flocked together by hydrogen bond action, is formed water cluster, is commonly called as water clusters, the size of the molecular cluster can not, it is expected that
It is generally made of 8~15 hydrones, and is that dynamically, average diameter is 2.6~6nm；And scintilla water is using special
Technique preparation, micel are 3~6 hydrone compositions, and average diameter 0.6bnm, activity is much larger than conventional deionization
The water of water, distilled water and nature, this be also the double-component aqueous PU plastic paint performance that is prepared using scintilla water not
It is same as the basic reason that conventional deionized water, tap water etc. are produced.Scintilla water improves the frost resistance of water paint, resists
Flow and drying property etc..
It specifically gets on very well, according to thermodynamic (al) calculating, if water is existed in the form of single hydrone, the fusing point of water is answered
It is -110 DEG C, boiling point should be 85 DEG C, but the fusing point of actually common water is 0 DEG C, and boiling point is 100 DEG C.Average 3~6 water
The micel of molecular composition scintilla water, and the micel of common water is made of 8-15 hydrone, therefore scintilla water
Fusing point and boiling point are far below common deionized water, distilled water, tap water, therefore the double-component aqueous PU plastic paint prepared
In northern cold winter, more difficult icing, the transport and construction in winter be safer.In addition, evaporation latent heat is lower, volatilization
Property it is stronger, further say, using scintilla water rather than common tap water, deionized water, distilled water preparation two-component
Drying property, the sag resistance of aqueous PU paint can be more preferable.
Compared with the prior art, the present invention has the advantage that
1, product of the invention has excellent adhesive force, sag resistance energy and scratch resistance capability, according to national standard GB/
The regulation of T9286-1988, the film adhesive tested can reach no more than 1 grade, or even to 0 grade, fully meet row
The performance of industry client needs.
2, product of the invention has used scintilla water as solvent, since scintilla water is different from the composition structure of light water
It makes, scintilla water activity is larger, and surface tension is smaller, and molecular structure arrangement is close neat, and fusing point and boiling point and heat of evaporation are remote
Lower than common water so that the aqueous double-component PU plastic paint prepared have good frost resistance, anti-sag and faster
Rate of drying significantly improves water paint in the drying and freeze proof problem of northern cold winter, improves double-component aqueous PU
Paint transport in winter and using safe, and surface effect is more more flat than the aqueous plastic paint using tap water or deionized water
Whole saturation.
3, product of the invention has excellent surface hardness, and according to the regulation of national standard GB/T6739-1996, test is obtained
Film coated surface hardness can reach H (Mitsubishi's pencil), it might even be possible to reach 2H (Mitsubishi's pencil), industry customer feedback is better than
Solvent based product.
4, product of the invention is using double-component aqueous PU as main film forming substance, ensure that including adhesive force, hardness, weather-proof
Property, alcohol resistance, gloss etc. are many to be had excellent performance, and is doped with one-component acrylic emulsion, is reduced production cost, also improves
