Abstract
A three-proof PU leather fabric relates to the technical field of structure of PU compound leather. A PU layer is compounded on one surface of a metal fiber fabric by a resin substrate, thereby having the characteristics of light weight, thinness, water resistance gas permeability and radiation resistance.
Description
Technical field
The utility model relates to the technical field of structures 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.
The utility model content
The utility model purpose be to design a kind of light, approach, have waterproof, ventilative, radiation-resistant three preventing PU leather facing material.
The utility model passes through the compound PU layer of resin bed material in the one side of metal fibre cloth.
The metal fibre cloth is the lining that stainless steel fibre and other fiber blend resultant yarn are woven into.
Simple, the easy operating of the utility model production method, 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 the high frequency electromagnetic radiation strength retrogression 28 decibels (dB), 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 utility model 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.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, coated one deck resin bed material 2 on metal fibre cloth 1, compound PU layer 3 on resin bed material 2.
Metal fibre cloth 1 is the lining that stainless steel fibre and other fiber blend resultant yarn are woven into.
Each functional parameter of product:
1, radiation proof function:
Technical standard
Shield ranges: 400MHZ-12GHZ
Microwave absorbs:〉15dB
The microwave radiation decay:〉28dB
The radiation proof rate reaches more than 99%, can wash 50 times.
2, electrostatic-proof function:
Technical indicator
3, water-proof function
Waterproof: can reach 3000～5000mmH
2O
Light transmission: cloth be can't see an eye to light, beautified outward appearance.
Tensile strength: 30N/cm
