Description
Technical field
The present invention relates to artificial synthetic leather field, more particularly to a kind of preparation method of high abrasion-proof PU synthetic leather fabric.
Background technology
PU leather is exactly the epidermis of polyurethane composition.It is widely used in makeing the dress of case and bag, clothes, footwear, vehicle and furniture now
Decorations, it has increasingly obtained the affirmative in market, and its application is wide, and quantity is big, as many as kind, be traditional natural leather without
What method met.Artificial leather, synthetic leather are an important components of plastics industry, are made extensively in national economy every profession and trade
With.Artificial leather, synthetic leather production have 60 years development history in the world, and China's development and production since 1958 are artificial
Leather, it is to develop industry earlier in China Plastics Industry.In recent years, Chinese artificial leather, synthetic leather industry development not
Only it is that the growth of production line is equipped by manufacturing enterprise, product yield increases year after year, variety design increases every year, and industry development mistake
There is the industry organization of oneself in journey, there is suitable cohesiveness, so as to Chinese artificial leather, synthetic leather enterprise, including correlation
Industry organization together, develops into an industry for having considerable strength.
Application No. CN201010516209.5 patent discloses a kind of environment-friendly type PU resins, and it is more that raw material includes oligomer
First alcohol, diisocyanate, dimethyl sulfoxide (DMSO) and dimethyl carbonate；A kind of environment-friendly type PU using the environment-friendly type PU resins as raw material
Leather, including surface layer, middle level and bottom, each layer raw material is by PU resins that mass percent is 40-60%, 2-10% tune
The solvent composition of toner, 30-50%；A kind of method for preparing environment-friendly type PU leather, by face stock composition be coated in from
Drying and cooling on type paper, by the feedstock composition in middle level coated in Drying and cooling on surface layer, by the feedstock composition of the bottom
Coated on middle level, it is Nian Jie with base fabric after Drying and cooling release liners are peeled off, carry out secondary drying.The invention solves existing skill
Organic solvent toxicity is big in PU resins in art, residual toxicity organic solvent in PU leather finished products, the technical problem of TVOC too high levels.
Especially suitable for production environment-friendly type PU resins, environment-friendly type PU leather.
But all it is that directly there is the inorganic material of wear-resisting functions by adding some in existing wearability PU leather product
To improve the wearability of PU leather, but inorganic material and the poor compatibility of polyurethane are not easy to disperse, and easily reunite, so as to influence
The performance of its wearability.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of preparation method of high abrasion-proof PU synthetic leather fabric.This
PU synthetic leather made from inventive method on the premise of the feel of PU synthetic leather is kept, can effectively improve the wearability of PU leather.
And the present invention is added with graphene in PU synthetic leather, it is possible to increase the dispersiveness of graphene, makes it be not easy to reunite.
The present invention concrete technical scheme be：A kind of preparation method of high abrasion-proof PU synthetic leather fabric, comprises the following steps：
1) Graphene powder is added in deionized water and is uniformly dispersed and adjusts pH value to be heated to 65-75 DEG C, so to 11-12
Afterwards while aluminum sulfate solution is added dropwise, while regulation pH is 6-7, after being added dropwise, stirring curing, washs to neutrality, dry, be made
Coated graphite alkene.
2) be ground after a coated graphite alkene is mixed with water, polyethylene glycol, wash, dry after obtain secondary cladding
Graphene.
3) PPG, secondary coated graphite alkene, dibutyl tin laurate and dimethylformamide are mixed and stirred
Mix uniformly, then add isocyanates, heating response, polyurethane resin is made.
4) take the part polyurethane resin, add mill base, with wet method slurry, wet method slurry is applied on base material, so
Base material is immersed in dimethyl formamide solution afterwards and solidified, finally takes out and washes, dries successively, wet method bass is made；
5) take the part polyurethane resin, after addition dimethylformamide, butanone and toner, with dry method slurry, will
Dry method slurry is applied in release liners, dries successively, after cooling, dry method veneer is made.
6) the wet method bass is bonded with the dry method veneer, successively after drying, cooling down, divests release liners, made
Obtain finished product.
The present invention is using graphene as the functional additive for improving PU synthetic leather anti-wear performances.Graphene has very strong
Physical property, it is possible to increase the wearability of PU synthetic leather.But because the compatibility of graphene and polyurethane is poor, in polyurethane
In be not easy to disperse, easily reunite.
Therefore, the first presoma by the use of sour aluminium as unformed aluminum oxide of the invention, forms colloid, in graphene table after reaction
Bread is covered with unformed aluminum oxide, and unformed oxidation aluminium surface contains great amount of hydroxy group, and reactivity is higher, while also improves stone
The compatibility and dispersiveness of black alkene and polyurethane.Then, the present invention has further coated polyethylene glycol, poly- second to graphenic surface
Glycol can participate in reaction in the synthetic reaction of polyurethane resin so that the associativity of graphene and polyurethane is more preferable, simultaneously
Because the compatibility of polyethylene glycol and urethane monomer is good, additionally it is possible to reduce the steric hindrance of graphene in the polymerization, enter
One step improves graphene dispersion, makes it be not easy to reunite.
In addition, although graphene can effectively improve the wearability of PU synthetic leather, PU synthetic leather as artificial fur clothing,
Artificial leather glove, the raw material of imitation leather cushion are, it is necessary to often and contact human skin.Graphene is in enhancing PU synthetic leather physical properties
While, because its particle is more coarse, can cause PU synthetic leather surface become to have it is crude, and can be jagged during skin contact
Sense, influences usage experience.And the present invention has carried out secondary cladding to graphene so that the harsh feeling of graphene particles significantly drops
It is low, so as to improve the feel of PU leather.
Further, in step 1), the quality amount ratio of Graphene powder and aluminum sulfate is 100:6-8.
Further, in step 2), the quality amount ratio of a coated graphite alkene and polyethylene glycol is 100:8-18.
Further, in step 3), PPG, secondary coated graphite alkene, dibutyl tin laurate and isocyanic acid
The quality amount ratio of ester is 90-110:1-3:1-5:15-25.
Further, in step 3), reaction temperature is 50-70 DEG C, reaction time 4-6h.
Further, in step 4), setting temperature is 30-40 DEG C, time 10-20min.
Further, in step 4), the coating weight of wet method slurry is 150-180g/m2.
Further, in step 5), the mass percent of the dry method slurry is：Polyurethane resin 55-65%, dimethyl
Formamide 20-30%, butanone 5-15%, the 4-6% of toner.
It is compared with the prior art, the beneficial effects of the invention are as follows：
1st, the present invention on the premise of the feel of PU synthetic leather is kept, can effectively improve the wearability of PU leather.
2nd, the present invention is added with graphene in PU synthetic leather, and can improve the dispersiveness of graphene, is not easy it
Reunite.
