Abstract
The invention relates to a resin compound for crazy horse leather, comprising urethane resin, dimethylformamide, stress color-changing wax powder, acetone and viscose fluff powder, wherein, the stress color-changing wax powder is hydroxide radical organic silicon. Compared with the prior level, the resin compound has better fluff scattering effect; therefore, after the made synthetic leather is kneaded, the fluff on the leather surface can grow, the fluff feeling is good and the fluff surface effect is good; after the leather surface is jacked up, the real leather feeling is great.
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 ofly can make polyurethane resin composition with strong kishke feel crazy cordovan that especially the leather surface feel of wool is good.
Background technology
Synthetic leather normally is laminated to the lamellar product that nonwoven fabric, woven or woven cloth are formed by combining by polyurethane resin composition, and its structure generally comprises base cloth and the polyurethane 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 present very popular on the market a kind of synthetic leather, 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, wherein used stress variable color wax powder (also to claim the variable color powder, commonly used as silica), because stress variable color wax powder does not have elasticity, when leather under stretching, jack-up, bending, external stress such as folding, change color can appear in the position that produces deformation, the wax powder can present the white of itself, and with the variation of deformation gradient, color presents gradual change feature from deep to shallow, generally have only corium just can accomplish such effect, but the synthetic leather that has added stress variable color wax powder can be accomplished this point.
In addition, crazy cordovan with also to add viscose glue fine hair powder in the polyurethane resin composition, acrylic fine hair powder waits the feel of wool and the visual kishke feel that increases leather, though after using the made crazy cordovan of viscose glue fine hair powder and acrylic fine hair powder to rub at present certain feel of wool is arranged, but staple length does not come out, the matte weak effect is from visually with in the sense of touch all being difficult to reach the effect of corium.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above crazy cordovan, provide a kind of can making to have strong kishke feel, especially the polyurethane resin composition of the crazy cordovan that the leather surface feel of wool is good with polyurethane resin composition.
Resin composition for crazy horse leather, it comprises polyurethane resin, dimethyl formamide, stress variable color wax powder, and wherein, this resin combination also comprises acetone, viscose glue fine hair powder, and described stress variable color wax powder is an organic hydroxy silicate.
Wherein polyurethane resin is the matrix material of the crazy cordovan of the present invention with polyurethane resin composition, dimethyl formamide (DMF) and acetone are the solvents of dissolve polyurethane resin, because the boiling point of DMF and acetone is different, when leather is carried out dried, both gradient volatilizations can improve the leather profile pattern.Wherein having added viscose glue fine hair powder increases the feel of wool and the visual kishke feel of leather surface after rubbing, longer but general hair is difficult to, the matte weak effect.Discover that through the inventor adding organic hydroxy silicate can address this problem.Organic hydroxy silicate can be used as stress variable color wax powder on the one hand, can give the effect of leather surface variable color, on the other hand, it can also be as moistening flatting agent, increase the permeability of whole composition, make the fine hair powder be dispersed in more uniformly in the composition, the fine hair of the synthetic leather of making leather surface after rubbing can grow, the feel of wool is good, matte is effective, and the jack-up leather surface can find that kishke feel is very strong.
The percentage by weight of each component is as follows:
Polyurethane resin 25%～35%
Dimethyl formamide 40%～45%
Acetone 15%～25%
Organic hydroxy silicate 4%～8%
Viscose glue fine hair powder 3%～5%.
The inventor finds to adopt the matte best results of the made crazy horsehair leather of the resin combination of aforementioned proportion.
About 0.2mm～the 0.8mm of villus length of described viscose glue fine hair powder.Villus length is that what make about 0.2mm～0.4mm is crazy horse undercoat leather; 0.5mm about what make is crazy Malaysia and China furs leather; 0.7mm about what make is the crazy horse leather that becomes mildewed.
Described polyurethane resin preferred aliphat polyurethane resin, the preferred 40GPa～80GPa (GPa=10 of its elastic modelling quantity
9Pascal).
This resin combination can also comprise 1%～3% calcium carbonate as filler.
Generally speaking, the present invention compared with prior art, the dispersion effect of fine hair is better in the resin combination of the present invention, the fine hair of the synthetic leather of making leather surface after rubbing can grow, the feel of wool is good, matte is effective, the jack-up leather surface can find that kishke feel is very strong.
The specific embodiment
Further set forth crazy cordovan polyurethane resin composition of the present invention below in conjunction with embodiment.
Embodiment 1
A kind of resin composition for crazy horse leather takes by weighing each raw material components according to the following weight proportioning: aliphatic polyurethane resin (elastic modelling quantity is 50GPa) 29%, DMF 42%, acetone 18%, organic hydroxy silicate 5%, calcium carbonate 2%, viscose glue fine hair powder (villus length is 0.3mm) 4%.
The production technology of this resin composition for crazy horse leather, concrete steps are as follows:
1.: accurately take by weighing DMF, acetone, organic hydroxy silicate, calcium carbonate fully stirred 3 minutes in reactor;
2.: about 45 minutes through ball mill grinding;
3.: after in the material that stirs, adding aliphatic polyurethane resin, viscose glue fine hair powder, fully stir more than 30 minutes.
The resin composition for crazy horse leather of the present invention that obtains by above-mentioned steps is a kind of yellow thick liquid, and pH value is approximately 6～7, and solid content is 26 ± 1%, and viscosity is at 1500～2000PaS in the time of 25 ℃.
The release liners coated technique is adopted in the coating of resin combination, and is specific as follows:
1) resin composition for crazy horse leather (optionally adding a small amount of colorant therein) with embodiment 1 gained is coated on the release liners, and the about 0.15mm of thickness was dried about 1.5 minutes for 130 ℃;
2) at 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) release liners is peeled off;
5) leather surface of the crazy cordovan of gained is rubbed line, can place boarding machine, rubbed line 1 minute for 80 ℃, leather surface grows fine hair.
Prepared crazy cordovan matte is effective, and jack-up leather surface color changeable effect is fine, and kishke feel is very strong.
