Abstract
The utility model relates to a double-component windproof breathable film which comprises a polytetrafluoroethylene base film formed through material mixing, blanking, extrusion, calendaring, stretching, sintering and solidifying; a micro-pore PU (Poly Urethane) layer is compounded on the polytetrafluoroethylene base film; the polytetrafluoroethylene base film has a thickness of 2-5 microns and an aperture of 0.5-3 microns; the micro-pore PU layer has a thickness of 3-6 microns. The double-component windproof breathable film is a diversified product, which is ultra-thin and more comfortable, has breathable, windproof and heat preservation functions, is used for preventing ultraviolet rays and is made of functional materials suitable for various sports, leisure, women and children and the like.
Description
Technical field:
The utility model relates to windproof ventilated membrane field, relates in particular a kind of two windproof ventilated membrane of component.
Background technology:
Along with the raising of people's living standard, people are also more and more higher to the requirement of quality of life, the for example requirement of people to CRUX dress ornament, wish that it is not only comfortable and easy to wear, lightweight, and will have the several functions such as ventilative, windproof, waterproof, antiultraviolet, moisture-inhibiting, and product on existing market does not all reach above-mentioned functions.
Microporous teflon membran is a kind of pliable and tough and whippy poromerics, porosity is high, even aperture distribution, there is the characteristic of permeable watertight, can be used as ventilative windproof film, disinfection filtering film, air cleaning filtration etc., it is outstanding that it has advantages of that many traditional filter membranes do not have, and its applicability is wide, is widely used in the fields such as clothes, family, medicine and chemical industry.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, and a kind of two windproof ventilated membrane of component is provided, and it is simple in structure, applied range.
Technology solution of the present utility model is as follows:
A kind of two windproof ventilated membranes of component, it comprises through batch mixing, base, extrudes, rolls, the polytetrafluoroethylene (PTFE) basis film of stretching and sintering curing processing, compound one deck micropore PU layer above of described polytetrafluoroethylene (PTFE) basis film.
As preferably, described polytetrafluoroethylene (PTFE) basis film thickness is 2～5 μ m, and polytetrafluoroethylene (PTFE) basis membrane aperture is 0.5～3 μ m.
As preferably, the thickness of described micropore PU layer is 3～6 μ m.
The beneficial effects of the utility model are:
The thickness of polytetrafluoroethylene (PTFE) of the present utility model basis film is 2～5 μ m, and average pore size is 0.5～3 micron, and porosity is more than 80%, filter efficiency 99%～99.9%, and it has ultra lightweighting, ultra-thin film, film has high temperature tolerance.
Polytetrafluoroethylene (PTFE) basis film of the present utility model and micropore PU layer are to shift by strippable paper at 100 DEG C～250 DEG C temperature the two component films that form, this pair of component film is ultra-thin, have more comfortableness, there is ventilative windproof and warming function, antiultraviolet, is suitable for the diversity product of the functional materials such as every motion, leisure, women and children.
Brief description of the drawings:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Embodiment, see accompanying drawing 1, a kind of two windproof ventilated membrane of component, it comprises through batch mixing, base, extrude, roll, the polytetrafluoroethylene (PTFE) basis film 1 of stretching and sintering curing processing, compound one deck micropore PU layer 2 above of described polytetrafluoroethylene (PTFE) basis film, is compounded to form two component films by release liners transfer method by micropore PU layer and polytetrafluoroethylene (PTFE) basis rete.
Described polytetrafluoroethylene (PTFE) basis film thickness is 4 μ m, polytetrafluoroethylene (PTFE) basis membrane aperture is 1 μ m, polytetrafluoroethylene (PTFE) basis film has heat-resisting quantity, air permeable waterproof, in the time of filminess, each square cun has nearly 9,000,000,000 apertures, the size of these apertures be water droplet volume ten thousand/, but than water vapour molecule large 700 times, can effectively prevent seeing through of aqueous water, and vaporous water molecular energy freely sees through.
Micro-pore on the film of polytetrafluoroethylene (PTFE) basis is the irregular alignment of multilayer, plays again anti-wind action, and it is higher by 40% than anti-demeanour, the thermal ressistance of general fabric.Can, because of washing, folding and wearing and tearing inefficacy very soon, not contain anti-oil substances simultaneously, can effectively intercept grease, chemicals etc.
The thickness of described micropore PU layer is 5 μ m, and micropore PU layer has comfortableness, and perspective performance is good, air permeable waterproof.
The utility model water proofing property is greater than 3000mm water column, and poisture-penetrability is greater than 10000g/m
2.24hr, dampness is less than 10m
2pA/W, temperature tolerance can reach 260 DEG C, the windproof EN14058 standard that reaches, uvioresistant is greater than 50+.
Above-described embodiment is the specific descriptions that the utility model is carried out; just the utility model is further described; can not be interpreted as the restriction to the utility model protection domain, those skilled in the art according to the content of above-mentioned utility model make some nonessential improvement and adjust all fall into protection domain of the present utility model within.
