Description
Technical field
The present invention relates to leather sector, more particularly to UHMWPE fibre three-dimensionals compound nonwoven cloth to be handled through water-base resin impregnation
High-strength anti-stab synthetic leather bass preparation method.
Background technology
Synthetic leather has been widely applied in every field, and synthetic leather bass is the semi-finished product of synthetic leather, usually wet method
Impregnate base fabric and form synthetic leather bass.Synthetic leather bass can be brought and do finished product.Suede can have been made both according to the difference of technique
Niu Bage, common synthetic leather, woven fabric etc..
Wherein, Synthetic Leather bass is the most widely used synthetic leather bass at present.Synthetic Leather bass
Filmogen be polyurethane resin, coating presence that polyurethane resin is formed, penetrability, poor air permeability, dress are not enough relaxed
The shortcomings that suitable.And because current polyurethane is in preparation process, a large amount of organic solvents can be used, it is not environmentally friendly enough.
On base fabric, the scrim material of synthetic leather bass is generally superfine fibre at present, but the intensity of superfine fibre, mould
Amount, chemical resistance, weatherability, wearability, anti-puncture poor-performing, and coefficient of friction is big, causes service life short, and can not
Meet the performance requirement of some high quality of products.
Application No. CN200810162448.8 Chinese patent discloses one kind and is used for wet production nano synthetic leather shellfish
This nano pulp and its wet processing, nano pulp are made up of following component (parts by weight)：Polyurethane resin is (with solid content
Exemplified by 30%) 100~300 parts, 1.0~9.0 parts of nanometer presoma, 0.2~10.0 part of inhibitor, 20~90 parts of filler, levelling
0.1~0.6 part of agent, 100~600 parts of diluent.Wet processing is：Coating --- solidification --- washing --- dry --- into
Volume.The present invention is not on the premise of the existing wet process technique of synthetic leather industry, equipment is changed, using special in-situ hybridization
Nano level inorganic particle is uniformly introduced in polyurethane coating by technology, so as to improve the breathable moisture permeability of synthetic leather bass,
The performance such as bacteria mildew-proof and uvioresistant.
Although above-mentioned synthetic leather bass improves the breathable moisture permeability of polyurethane to a certain extent, with science and technology
Progress, people gradually step up to synthetic leather bass requirement, and its performance is still not ideal enough.And it uses common material conduct
Base fabric, in base fabric intensity, modulus, chemical resistance, weatherability, wearability, anti-puncture aspect of performance still price differential, itself and rub and be
Number is big, causes service life short, and can not meet the performance requirement of some high quality of products.

Cloth is formed using thick denier UHMWPE fiber yarns, fine-denier UHMWPE chopped fibers, water-soluble chopped fiber as material knitting；The main impregnation
During, master contains in immersion liquid and contains graphene modified aqueous polyurethane resin.
The present invention is using UHMWPE as main raw material(s).UHMWPE and aramid fiber ratio, UHMWPE fibers have higher strong
Degree, modulus, specific strength, specific modulus and sound wave transmission speed.Meanwhile UHMWPE fibers than aramid fiber weatherability more
It is good.It has advantages below:(1) wear-resistant very remarkable, mortar wear test shows, will than metals such as general carbon steel and copper
It is wear-resisting several times, more wear-resisting than nylon 4 times；(2) impact strength is high, bigger than PA6 and PP 10 times；(3) jerk can be absorbed and prevented
Noise；(4) coefficient of friction is very low, is small, energy self-lubricating far beyond nylon and other plastics;(5) it is not easy to adhere to foreign matter, during slip
There is extremely excellent antisticking characteristic；(6) it is resistant to chemical etching, and maskable atomic radiation；(7) operating temperature range can be from -265
DEG C arrive+100 DEG C, when low temperature is to -195 DEG C, remain to keep good toughness and intensity, will not embrittlement；(8) it is non-toxic, without dirt
Dye, recyclable recycling, being compared with other plastics has good heat endurance and non-absorbency, can keep dimensional accuracy not
Deformation；(9) cost is cheap.
