Description
Technical field
The present invention relates to the manufacture craft technical field of PU composite lether.
Background technology
PU synthetic leather in the past is to be base cloth with the polyester cotton mostly, is coated with polyurethane coating in one side, to obtain to have the functional fabric of water-proof function, also with utilizing antistatic afterfinish method exploitation to have the electrostatic-proof function lining.Make product in order to reach functional effect in the past, and often need add thick coating, and caused the lining product to have thick and heavy sense, airtight, be unfavorable for that the expansion of product is used, even make tent, also be unfavorable for packing, transportation, assembling.
As everyone knows, electromagnetic radiation has at present become the fourth-largest public hazards after water pollution, atmosphere pollution, noise pollution.Broad research shows that electromagnetic radiation relates to nervous function, circulatory function, function of immune system and life growth function to the harm of health, can cause tens of kinds of diseases, malignant changes such as severe patient meeting leukemogenesis, lung cancer.Along with the raising of people's understanding, the public will extensively take safeguard procedures, the injury that reduces and avoid electromagnetic radiation to cause.
Summary of the invention
The object of the invention be to invent a kind of light, approach, have waterproof, ventilative, radiation-resistant three preventing PU leather facing material.
The present invention is at the compound PU layer of the one side of metal fibre cloth.
Another purpose of the present invention is to provide the production method of above-mentioned three preventing PU leather facing material.
The inventive method step is:
1) one side in release liners is coated with the PU coating paste that vacuumizes, oven dry;
2) be coated with bed material on the PU coating, baking is to half-dried;
3) applying metal fiber cloth on bed material, oven dry;
4) leave standstill after 24 hours and separate release liners.
Bake out temperature is 120 ± 5 ℃ in the step 1).
Step 2) bake out temperature is 100 ± 5 ℃ in.
Bake out temperature is 130 ± 10 ℃ in the step 3).
Described PU coating paste viscosity is 3000cps, before the coating, places in the vavuum pump, takes out 2 ± 0.1 hours at 0～0.1 atmospheric pressure.
Described PU coating paste is the dilution of polyurethane fabric resin, and wherein, the weight ratio of each component is respectively: resin 100, N, dinethylformamide (DMF) 10, MEK (MEK) 10, toluene (TOL) 70.
Described step 2) bed material viscosity is 2700cps in, and bed material is the dilution of polyurethane bed material resin, and the weight ratio of each component is respectively: resin 100, N, dinethylformamide 5, MEK 10, toluene 50.
Metal fibre cloth of the present invention is the lining that stainless steel fibre and other fiber blend resultant yarn are woven into.
Simple, the easy operating of production method of the present invention, the product tool of formation are in following function:
One, radiation proof function:
Because base cloth adopts the metal fibre cloth, it is the lining that adopts stainless steel fibre and other fiber blend resultant yarn to be woven into, so, being compounded to form three prevention fabrics with PU has good screen and keeps away and absorb the electromagnetic wave function, absorption band is wide, the absorptivity height, maskable and absorption far infrared, absorption band is wide.Fiber high-modulus, high strength after testing, can intercept high-frequency electromagnetic wave excitation, can make more than 28 decibels of the high frequency electromagnetic radiation strength retrogressions (d B), shielding and the electromagnetic wave that absorbs more than 99% can prevent the microwave secondary pollution that causes of secondary reflection again, can with the human body cell molecular resonance, activating cell, promote microcirculation and metabolism, resist the disease keeps health, have bacteria resistance function, make human body avoid the invasion and attack of bacterium.Be more suitable for protective cover, tent, application such as radio and television, communication in the military project various device.
Two, electrostatic-proof function:
Since adopt above PU compounded fabric energy conduction surfaces electric charge, thereby remove surface charging, after testing, the cloth density of surface charge≤12/m
2, ready-made clothes carried charge≤0.2 μ C/ spare.
Principal character
1. adopt nanometer high-property fiber conduction technology, can eliminate the static that the lining surface produces fast, performance is higher than the standard in Japan's " electrostatic safety guide ".
2. through after this technical finesse, every physical index of lining can not change, and the gloss nature is soft.
3. this high-performance conductive fiber is water insoluble, high temperature resistant, not influenced by washing, and function is lasting.
The production and processing cycle long, make a gesture of measuring big, cost is low, be suitable for and large-scale production.
Three, water-proof function
Adopt unique production process that the starch adhesive material that configures is put into vavuum pump and be evacuated down to following 2 hours of 0 atmospheric pressure.Effectively eliminated pulp surface tension force, made and when coating, reduced surperficial depressed phenomenon, made leather hand feeling plentiful, smooth.
Select for use the two-liquid type bed material to make adhesive simultaneously, after the employing patch, do not peel off, constant temperature leaves standstill " non-stripping " method of 24 hours, makes product that splendid intensity and hydraulic pressure be arranged.
The present invention can be widely used in field and personnel frequent and that electromagnetic wave is come into contacts with such as military project, space flight, radio and television, communication, oil, high voltage transmission line.Simultaneously because electromagenetic wave radiation is ubiquitous in people's daily life, anti-electromagnetic radiation, antistatic, waterproof fabrics provide selectable product for each field and ordinary consumer.
The specific embodiment
