Description
Technical field:
The invention belongs to composite material for weaving and technology textile field, relate to the frivolous flexible material technology that human body or environment temperature are heat insulation and protect, be a kind of heat insulation soft thin composite fabric, preparation method and its usage, this compound fabric is heat insulation applicable to the physical protection and the environment of special occasions such as military affairs, geological prospecting, ocean, space flight, physical culture, rescue.
Background technology:
Physical protection is the cause of protective materials research, and soft protective materials is human the explore world and the cosmic time, the necessary condition that still can normal running under special occasions moves.Most high performance flexible protective investigation of materials and patent (KoTse-Hao.Fire-fighting appliance.USP 5153055,1992; Smith WN, Burnham T.Fireblocking textile insulation.USP 5776745,1998; Fujita M, Wakuta Y, Kumakawa S.Protective goods.USP 5935882,1999; Beckmann FD.Heat and Sound insulationelement.EP 1028202,2000; Albrecht G, Sickinger A, Schmuhl HJ.Casing for a thermalturbo machine having a heat-insulating liner.USP 4405284,1983) originate in the requirement of these application of special occasions.Its basic demand is light, reduces burden; Gentle, be convenient to motion and reduce obstacle and energy consumption; Various heat, light, electro ultrafiltration and radiation are resisted in protection; Prevent that hitting of object power from dashing and the infringement of organism or harmfulness gas, liquid, solid body.The wherein protection of temperature, promptly cold environment and thermal environment and human body isolated is basic contents the most wherein.As the cold and radiant heat environment in the space, environment such as polar region, volcano exploration.
At present two kinds of methods are mostly adopted in the protection of hot and cold environment, the one, adopt rigid body to make the body or removable frame body, though protection effect is good,, can hold many people can control well, but heavy, mobility is poor, the cost height; Another is to adopt flexible material to make protective garment to be directly used in human body and to need temperature control, operating mechanism that again can without hindrance motion, though protection effect is slightly poor, lightweight, softness, mobility strong, zoarium directly protect.The thermal isolation protective materials that the combination of hard and soft property material is arranged certainly, but rigid element mostly is joint and motionless position greatly, and take into account other protection.Therefore in essence, the isolated and protection of temperature field, the high-quality heat-proof quality of the material of flexible material own and its softness, lightweight feature are enough to form separately thermally protective materials.
Because the requirement thermal insulation of most thermal isolations protection (being that thermal conductivity factor is zero), airtight (be gas flow or see through equal zero), though vacuum layer can be accomplished this point ideally, it is the rigid body structure.The most traditional mode provides form thermal insulation (Zhang Yuxiang, novel warming compound fabric, Chinese patent ZL00234313.4,2000 that more thick and heavy fleeces goods add back boxing and outer cover; Ellis WG.Protective garments.USP4034417,1977; Anderson CW.Improvements relating to composite laminated sheets.GB1089873,1967; Kosmala H.Hand protection for hot workplaces.WO9722385,1997).In theory hot and cold environment all is suitable for, but too thick and heavy, influence is moved and is carried.Therefore, adopting the mode of structural design and combination of materials, improve the thermal isolation of flexible material, reduce the gravimetric thickness of material, increase flexibility, is that people wish to obtain and constantly exploratory development.
Summary of the invention:
The purpose of this invention is to provide a kind of heat insulation soft thin composite fabric.
Purpose of the present invention can provide the preparation of above-mentioned heat insulation soft thin composite fabric.
Another object of the present invention provides the purposes that a kind of above-mentioned heat insulation soft thin composite fabric comprises this fabric.
Principle of the present invention be by the design compound fabric one side be the coated fabric of high-and low-temperature resistance and airtight performance; Another side is the coated fabric of soft, ultra-thin, frost-free, dew; Middle for having reflection, heat insulation, the airtight ultra-thin composite membrane of high polymer metal, or between this composite membrane, add again utmost point light soft, thickness and dimensional stability be good, can be when the compound fabric bulk deformation, guarantee the constant mesh liner fabric of distance between composite membrane, constitute with a system, efficient and the thermal protective system that people-oriented with this, realize thermal isolation and protection under lightweight, the soft condition.
The primary structure of compound fabric of the present invention and act as three parts: high-and low-temperature resistance skin, thermal isolation intermediate layer and comfortable soft outer layer.
A. the high-and low-temperature resistance skin is to be formed after handling through blade coating, calendering coating by high-performance terylene, polyamide fibre or kevlar fabric, plays the direct isolation to outside hot-cool environment, and protects the stable of whole compound fabric size and form.Used coating is silicon rubber or polyimides or polytetrafluoroethylene (PTFE).Itself not only has the high-and low-temperature resistance effect this coated fabric, and has the feature of airtight, reverberation, low thermal conductivity.
B. the thermal isolation intermediate layer is made up of the composite membrane that several layers (2～20 layers) high-polymer membrane and metal laminate form, or adds lining meshi fabric composition between this composite membrane again.Described high-polymer membrane is terylene, polytetrafluoroethylene (PTFE) or polyamide fibre film; Described metal is aluminium, aluminium alloy or gold; Described high polymer metal composite film is the laminate structures film by the sandwich structure of high polymer folder metal; Described lining meshi fabric be by terylene or polyamide fibre or aramid fiber braiding be shaped net-like structure-fibrous.The effect of high polymer metal composite film is that the high-polymer membrane on two surfaces forms low thermal contact conductance, and middle folded metal level is that highly reflective is heat insulation, and composite membrane is realized the thermal isolation effect of individual layer thus originally as airtight gas impermeable material.Because composite membrane is a multilayer material, so the space of interlayer also can form the thermal isolation of gas.And the thermal conductivity factor of still air is low, so contacting between the convection current that the control interfloor distance reaches gas between key-course and composite membrane.Stabilizing distance between composite membrane contacts with avoiding, and also can realize by the wrinkling processing and the lining net mode of film, and the former increases bedding void and reduces contact-making surface; But latter's direct control layer spacing, and when the compound fabric bulk deformation, the variation that the composite membrane spacing do not take place with contact.
C. comfortable soft outer layer is the another side of compound fabric, mainly is at the normal temperature condition environment, uses internal layer (as protective garment) so mostly be greatly.Also use to be skin, as the outer cover in hot and cold mechanism source.This layer is the fabric that is formed through dip coating or blade coating by polyamide fibre, terylene, polypropylene fibre or other textile fibers, and its softness, ultra-thin, airtight and surperficially play little suede has the function of surperficial moisture absorption effect and anti-frosting, condensation.Used coating is polytetrafluoroethylene (PTFE) or Polyurethane or silicon rubber.This fabric itself is low heat conductivity, light material, and has good mechanical performance and durability.
