The additional aspect and advantage of the present invention will be set forth in part in the description, and will partly become from the following description
Obtain substantially, or recognized by the practice of the present invention.
Brief description of the drawings
The above-mentioned and/or additional aspect and advantage of the present invention will become in the description from combination accompanying drawings below to embodiment
Substantially and it is readily appreciated that, wherein：
Fig. 1 is the method flow schematic diagram according to an embodiment of the invention for preparing sealing wax suit.
Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
In addition, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importance
Or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can be expressed or
Implicitly include at least one this feature.In the description of the invention, " multiple " are meant that at least two, such as two, three
It is individual etc., unless otherwise specifically defined.
In one aspect of the invention, the present invention proposes a kind of sealing wax suit.According to an embodiment of the invention, the sealing wax
Suit includes：First sealing wax component and the second sealing wax component, the first sealing wax component can include：The water-based tree of 60~70 parts by weight
Fat, the color stuffing of 5~20 parts by weight, the auxiliary agent of the polytetrafluoroethylwax wax of 0.5~1 parts by weight and 0.1~17.4 parts by weight；Second
Sealing wax component can include：The isocyanate curing agent of 30 parts by weight, wherein, the first sealing wax component is distinguished with the second sealing wax component
It is arranged in different containers.Inventor has found that the aqueous polyurethane contained in the first sealing wax component is multiphase film forming, first when
After most of moisture evaporation, emulsion particle contacts with each other, and forms closelypacked structure, remaining moisture and solidification agent molecule are then
It is in the gap location of emulsion particle.With the further evaporation of moisture, emulsion particle starts to condense, and forms more close six side
Shape arrangement architecture.At the same time, the isocyanate molecule in the second sealing wax component is diffused into the interface and its inside of emulsion particle,
Crosslink curing reaction.The film-forming mechanism also may be interpreted as aqueous polyurethane system from oil-in-water state to Water-In-Oil
Transformation.First sealing wax component is excessive or the second sealing wax component is crossed sufficient cross-linking and curing reaction can not occur at least, causes paint film
Slow drying speed, hardness is relatively low after film forming；First sealing wax component is very few or the second sealing wax component is crossed and at most causes excessive isocyanide
Acid ester molecules produce reaction with water and cause to waste, and cause cost to raise.Thus, inventor has drawn above-mentioned water by many experiments
Paint suit in sealing wax component optimum proportioning, using the proportioning sealing wax component sealing wax suit can pass through in use by
The the first sealing wax component and the second sealing wax component being separately positioned in different vessels are according to mass ratio (4~8)：1 mixing, can be obtained
7g/L sealing wax is not higher than to VOC, so as to significantly reduce the health hazard of workmen and user, and the sealing wax
Rate of drying is fast in work progress, and can be effectively formed the lacquer painting with excellent feel and scratch resistance, while into
This is cheap, so as to be used in guardrail surface, can significantly improve the quality of guardrail.

At least one of agent, dispersant, wetting agent, water and thickener, for example, auxiliary agent can include simultaneously nertralizer, defoamer, into
Film auxiliary agent, dispersant, wetting agent, water and thickener.Inventor has found that nertralizer act as adjusting paint solution pH value, and it is in
Have the function that to adjust paint solution pH with the free acidity in paint solution；Defoamer is used to eliminating bubble in paint solution, defoamer be with
The form of particulate is penetrated into the system of foam, and when foam will produce, the defoamer particulate being present in system can be broken rapidly
The elastic membrane of bad bubble, suppress the generation of foam, if foam has produced, after the defoamer contact foam of addition, that is, capture
The hydrophobic end of the chain of foam surface, through sprawling rapidly, very thin double film layers are formed, further diffusion, stratiform intrusion, substitute former foam
Membranous wall, the surface tension of defoamer in itself is very low, and the membranous wall of the vacuolar membrane containing defoamer part can be made gradually thinning, and bubble
Drawn by the big film layer strength of circumferential surface tension force, whole bubble can produce the imbalance of stress, so as to cause the rupture of bubble；
Dispersant makes the solids in paint solution be stably dispersed in medium, is on the one hand adsorbed in the surface of solid particle, makes cohesion
Solid particles surface is easy to moisten, and the dispersant of another further aspect polymer electrolyte can form adsorption layer on the surface of solid particle, make
The electric charge increase of solid particles surface, improves the intergranular reaction force for forming steric hindrance, another aspect can make solid grain
Sublist face forms bilayer structure, and outer layer dispersant polar end has compared with strong affinity with water, adds solids and moistened by water
Wet degree, and it is remote because of electrostatic repulsion between solid particle, another aspect can make system uniform, suspendability increase, no
Precipitation, makes whole system physico-chemical property the same；Wetting agent is by coating occurring in construction and film forming procedure some changes pair
Coating property is adjusted, and coating is had good levelling；Thickener is used for the viscosity for improving paint solution.
According to still another embodiment of the invention, each component content is not particularly restricted in auxiliary agent, people in the art

Neutralization agent content is too low to be caused paint solution pH value relatively low and then influence storage stability；Defoamer is very few to cause bubble on the high side,
It is excessive paint film to be made to be also easy to produce shrinkage cavity again；Coalescents can excessively influence the water resistance of paint film；Dispersant is very few to be caused to paint
Liquid is uneven, and storage produces bleeding；Thickener is very few to cause sealing wax viscosity relatively low, can excessively make sealing wax viscosity higher.
According to the specific embodiment of the present invention, the particular type of nertralizer is not particularly restricted, art technology
Personnel can be selected according to being actually needed, and according to the specific example of the present invention, nertralizer can be selected from dimethyl
At least one of monoethanolamine and multifunctional assistant AMP-95.Inventor's discovery, dimethylethanolamine and multifunctional assistant AMP-
95 can have the function that to adjust pH by the free acidity neutralized in paint solution, and they are relatively low compared with smell for the nertralizers such as ammoniacal liquor.
According to another specific embodiment of the present invention, the particular type of defoamer is not particularly restricted, this area skill
Art personnel can be selected according to being actually needed, and according to the specific example of the present invention, defoamer can be selected from polyethers
