Description
Technical field
The present invention relates to Waterborne synthetic leather slurry fields, and in particular at a kind of aqueous heat discoloration printing of use for synthetic leather
Manage agent and its preparation method and application.
Background technology
Waterborne synthetic leather is with its excellent feature of environmental protection, the durability of manufactured goods and makes us pleasing style and is increasingly becoming
Remove from office the new lover of class product in the market.As the high-end product in synthetic leather field, heat discoloration synthetic leather is deep by Downstream Market
Favor, but the production method of heat discoloration synthetic leather is only limitted to patent CN107604684A and CN206011870U announcement such as at present
Dry process, also have the solvent type heat discoloration synthetic leather dry method slurry announced using such as patent CN101967755A as original
Material.Though above-mentioned dry process or raw material can produce heat discoloration synthetic leather, dry process is being criticized because heat discoloration layer exists
Quantify in production process that there are face layers to be easy cracking and the bad phenomenon of levelling, and dry method is scraped using dise knife painting, product cost compared with
Height, while solvent type slurry has larger harm and influence for constructor's body and environment.
Waterborne synthetic leather is that synthetic leather aftertreatment technology is raw materials used with surface conditioning agent, is to determine Waterborne synthetic leather product
The key raw material of style.Waterborne synthetic leather is tradition such as stress discoloration, throwing with surface printing inorganic agent currently on the market
Light wipes color, wipes burnt class product, though the synthetic leather after such product treatment has the surface effect close to corium and different style,
But it far can not meet consumer demand in terms of intelligent and technology sense.
Invention content
It is an object of the invention to break through dry fabrication method and solvent type synthesis of the temperature-sensing color-changing material as synthetic leather
Slurry is used as synthetic leather raw material, provides a kind of synthetic leather post-processing aqueous heat discoloration printing treatment agent, passes through this inorganic agent
Synthetic leather after printing treatment can not only generate different colors with variation of the ambient temperature in different temperatures section and become
Change, while there is easy to operate, saving material, to constructor's body and environment without any the advantages of endangering.

~5 microns.Wherein the content of heat discoloration pigment will be controlled strictly, and content is too high to will produce reunion, and content is too low, can influence
Color changeable effect.The particle size of microcapsules influences dispersibility and durability, and grain size is excessive to be then easy breakage, and grain size is too small, disperses
Portion is uniform.
Preferably, the heat discoloration pigment in the present invention changes colour for multistage, i.e., shows spy respectively in multiple temperature ranges
Fixed color.
It is highly preferred that the heat discoloration pigment by the first heat discoloration pigment and the second heat discoloration pigment according to weight
Than (1-2)：(0.5-1.5) is formed, and the discoloring temperature of the first heat discoloration pigment is 28 DEG C, the discoloration of the second heat discoloration pigment
Temperature is 40 DEG C.First heat discoloration pigment is warming up to 28 DEG C or more rose bleach, and the second heat discoloration pigment is warming up to
40 DEG C or more bright red bleach.Using this characteristic, this first heat discoloration pigment, the second heat discoloration pigment are matched by difference
Use for synthetic leather aqueous surface printing treatment agent, the synthesis through this inorganic agent printing treatment is made than adding in aqueous polyurethane emulsion
After leather dries and the products such as shoes, luggage are made, because the stability of its microcapsule structure, wear-resisting scratch resistance and chemical resistance are excellent, no
Only there is three-dimensional sense and stereovision, while will present the color (i.e. large red) of 40 DEG C of pigment itself between 28 DEG C~40 DEG C,
It is mixed that two kinds of heat discoloration pigment are then presented at 28 DEG C or less in the color that will present the non-printing treatment bottom embryo of synthetic leather at 40 DEG C or more
The color of conjunction.
Preferably, the flatting silica is micron order aerosil.
It is highly preferred that the model R972 or TS100 of the micron order aerosil.

It is including following the invention also discloses the method prepared such as the aqueous heat discoloration printing treatment agent of above-mentioned use for synthetic leather
Step：
1) waterborne polyurethane resin, aqueous wetting dispersing agent, washing antifoaming agent are mixed under the rotating speed of 400~600r/min
Close stirring 10min；
2) under the rotating speed of 800~1200r/min, aerosil, heat discoloration pigment, sediment ripples powder, aqueous is added
Thickener stirs 30min；
3) under the rotating speed of 400~600r/min, be added aqueous defoamer and water adjust viscosity be 1200~1500cps simultaneously
10min is stirred, until the aqueous heat discoloration printing treatment agent of use for synthetic leather can be obtained by stirring evenly.
Prepared by a kind of aqueous heat discoloration printing treatment agent of above-mentioned use for synthetic leather or the above method
Purposes of the surface conditioning agent on waterborne polyurethane synthetic leather surface conditioning agent.
Compared with the prior art, the present invention has the following advantages：
First, heat discoloration pigment used herein is a kind of organic compound of microcapsule structure, in different temperatures
Certain electron exchange can be generated in range and then pigment intrinsic colour is made to change.Using this characteristic, by this two kinds or
The camouflage paint (such as 28 DEG C of rose bleach, 40 DEG C of bright red bleach) in a variety of difference temperature-sensitive sections is added to by different ratio
Use for synthetic leather aqueous surface printing treatment agent is made in aqueous polyurethane emulsion, the synthetic leather drying through this inorganic agent printing treatment
And after the products such as shoes, luggage are made, because the stability of its microcapsule structure, wear-resisting scratch resistance and chemical resistance are excellent so that product
Not only have three-dimensional sense and stereovision, while can with variation of the ambient temperature in different sections generate color change (for example,
The color (i.e. large red) that will present 40 DEG C of pigment itself between 28 DEG C~40 DEG C will present synthetic leather at 40 DEG C or more and not print
The color of two kinds of heat discoloration pigment mixing is then presented at 28 DEG C or less for the color for handling bottom embryo).It, can profit using same principle
It is combined collocation between camouflage paint with different form and aspect and with form and aspect difference temperature-sensitive section to synthesize after controlling printing treatment
Remove from office the color change of product surface.
Second, the present invention is aqueous environment protection material using raw material, VOC free volatilization and residual without toluene, DMF equal solvents
It stays, constructor and environment will not be caused damages and be influenced in handling printing process.
In addition, this inorganic agent is operated using gravure process, can be carried out according to synthetic leather plant produced line equipment
Adjust printing technology, the face that can be carried out with 80,100 or 120 mesh treatment tubes layer is changed colour processing, also using different pattern print roller into
Row printing treatment.Treatment process is scraped compared to the painting of dry method dise knife, this slurry is used as post-processing and makes heat discoloration leather, it is not easy to go out
Existing film cracking, while different meshes roller is arranged in pairs or groups, energy high degree improves the phenomenon of film levelability difference and saves material.
After handling and drying, the pattern on synthetic leather surface regular form and aspect can be carried out according to different temperatures section and light and shade changes, greatly
Amplitude also reduces product cost while improving aesthetic feeling and value of the product.
