Abstract
The invention relates to a resin compound used for crazy horse burnished leather, comprising polyurethane resin, dimethylformamide, floss powder, color-changing powder, acetone and epoxide resin, wherein, the color-changing powder is modified silicon dioxide and the melting point of the modified silicon dioxide is between 55 and 80 DEG C. Compared with the prior art, the crazy horse burnished leather prepared by the resin compound has good burnished archaizing effect, is close to corium, is smooth in the leather surface and has good scratch resistant and wear resistant performances.
Description
Technical field
The present invention relates to a kind of use for synthetic leather fabric resin, be specifically related to the crazy horse leather polyurethane resin composition, more particularly, a kind of polyurethane resin composition that can make crazy horse leather with strong kishke feel.
Background technology
Synthetic leather normally is laminated to the lamellar product that non-woven fabrics, woven or woven cloth are formed by combining by polyurethane resin composition, and its structure is generally wrapped base cloth and the urethane resin top layer that is attached on the base cloth.The top layer is mainly played decoration and is made outward appearance reach the effect of imitative natural leather.
Crazy cordovan is a kind of synthetic leather of popular very on the market now, and the color changeable effect that its surface is confused and disordered, kishke feel is arranged, jack-up coming can present leather surface occupies the status of expensive goods in synthetic leather market.
The employed resin combination of more existing crazy cordovans is a polyurethane-type, add the variable color powder and (also claim stress variable color wax powder, commonly used as silicon-dioxide), because the variable color powder does not have elasticity, when leather is stretching, jack-up, crooked, the folding grade under the external stress, colour-change can appear in the position that produces deformation, the variable color powder can present the white of itself, and with the variation of deformation gradient, color presents gradual change feature from deep to shallow, had only corium just can accomplish such effect in the past, and can accomplish this point but the employed resin combination of existing crazy cordovan has added the variable color powder; Wherein often add viscose glue fine hair powder, acrylic fine hair powder waits the feel of wool that increases leather surface slightly, particularly during the jack-up variable color, color changeable effect is more near corium.
When wiping, rubbing down or scribing are wiped the leather surface of burnt leather, can produce empyreumatic color changeable effect, certain antique effect is arranged, in general have only the corium leather just can accomplish like this, existing crazy horse leather difficulty accomplishes to wipe burnt effect, and promptly enables to wipe Jiao, the also wear-resisting inadequately scratch resistance of leather surface.
Summary of the invention
The objective of the invention is to overcome above shortcoming, a kind of polyurethane resin composition that can make the crazy horse leather with strong kishke feel is provided.
A kind of crazy horse leather resin combination, it comprises urethane resin, dimethyl formamide, acetone, fine hair powder, variable color powder, and wherein, this resin combination also comprises Resins, epoxy, described variable color powder is an improved silica, and the fusing point of improved silica is 55 ℃-80 ℃.
Wherein urethane resin is the body material of crazy horse leather of the present invention with resin combination; Dimethyl formamide (DMF) and acetone are the solvents of dissolve polyurethane resin, because the boiling point of DMF and acetone is different, when leather was carried out drying treatment, both gradient volatilizations can improve the leather profile pattern; Particularly the present invention has adopted improved silica as the variable color powder, and the fusing point of improved silica is 55 ℃-80 ℃, wiping at normal temperatures, rubbing down or scribing leather surface, particularly wiping apace, rubbing down or scribing leather surface, fricative instant heat is very big, be enough to make improved silica to reach fusing point and fuse, so leather surface there is empyreumatic color changeable effect, similar corium; Wherein add the fine hair powder and make after the crazy cordovan wiping that makes, the rubbing down slightly hairy, mainly be when making leather surface jack-up color changeable effect more near corium; Also added Resins, epoxy in addition in the present composition, Resins, epoxy is a kind of thermosetting resin, be dissolved in acetone, epoxy resin cure shrinking percentage after the curing is little, good stability, corrosion-resistant good, therefore the scratch resistance wear resisting property is good, adds the scratch resistance wear resistance that Resins, epoxy can improve the crazy horse leather of making.
The weight percent of each component is as follows:
Urethane resin 25%～35%
Dimethyl formamide 30%～40%
Acetone 15%～25%
Improved silica 5%～10%
Fine hair powder 2%～4%
Resins, epoxy 1%～5%.
The contriver finds to adopt the burnt antique effect the best of the wiping of the made crazy horse leather of the resin combination of aforementioned proportion.
This resin combination can also comprise 1%～3% flow agent, makes that the leather surface of making is more smooth.
Described fine hair powder preferred acrylic fibers fine hair powder or viscose glue fine hair powder.
About 0.2mm～the 0.8mm of the villus length of described fine hair powder.
Described urethane resin preferred aliphat urethane resin, the preferred 40GPa～80GPa (GPa=10 of its Young's modulus
9Pascal).
Generally speaking, the present invention compared with prior art, the burnt antique effect of the wiping of the crazy horse leather that resin combination of the present invention makes is good, kishke feel strong and leather surface is more smooth, the scratch resistance wear resisting property is good.
Embodiment
Further set forth crazy horse leather resin combination of the present invention below in conjunction with embodiment.
Embodiment 1
A kind of crazy horse leather resin combination takes by weighing each feed composition according to the following weight proportioning: aliphatic polyurethane resin (Young's modulus is 50GPa) 30%, DMF 35%, acetone 20%, Resins, epoxy 3%, improved silica (fusing point is 60 ℃) 7%, flow agent 2%, acrylic fibers fine hair powder (villus length is 0.2mm) 3%.
This crazy horse leather production technique of resin combination, concrete steps are as follows:
1.: accurately take by weighing DMF, acetone, improved silica, flow agent in reactor, fully stirred 3 minutes;
2.: about 45 minutes through ball mill grinding;
3.: after in the material that stirs, adding aliphatic polyurethane resin, Resins, epoxy, acrylic fibers fine hair powder, fully stir, stir more than 30 minutes.
The crazy horse leather resin combination of the present invention that obtains by above-mentioned steps is a kind of faint yellow viscous liquid, and pH value is approximately 6～7, and solid content is 25 ± 1%, and viscosity is at 1500～2000PaS in the time of 25 ℃.
The separate-type paper coated technique is adopted in the coating of resin combination, and is specific as follows:
1) crazy horse leather with embodiment 1 gained is coated on the separate-type paper with resin combination (optionally adding a small amount of colorant therein), and the about 0.15mm of thickness was dried about 1.5 minutes for 130 ℃;
2) at the first step gained resin coating one deck common polyurethane resin slurry, the about 0.15mm of thickness was dried about 15 seconds for 110 ℃;
3) wet method Base is fitted in the resin layer surface of above-mentioned gained, about 1.5 minutes of 130 ℃ of oven dry;
4) separate-type paper is peeled off;
5) leather surface of the synthetic leather of gained is thrown Jiao's (it is burnt to place polishing machine to throw)
The leather surface of the crazy horse leather of gained has the metachromatism of burning, and antique effect is arranged, and kishke feel is very strong, and leather surface is more smooth, and the scratch resistance wear resisting property is good.
