Description
Technical field
The invention relates to a kind of Waterproof Breathable film and manufacture method thereof with heat insulation function.The invention particularly relates to a kind of phase-change microcapsule is sneaked in the Waterproof Breathable material and hold the Waterproof Breathable film and the manufacture method thereof of temperature function to make tool.
Background technology.
The dress materials of being engaged in outdoors in early days mostly are to use nature material made, but along with development of science and technology, present most of outdoor clothes all adopt advanced artificial material, have only that the nature material that the high-performance of can not be substituted is arranged of only a few has been saved as eider down.The outdoor activity clothes require to make the advanced village of the high-tech that has only only a few material to be used to modern outdoor activity clothes to the harshness of material.For the requirement of being engaged in the outdoors clothes, in general need possess insulation, Waterproof Breathable, light etc.So-called water proof and moisture permeable material typically refers to the internal layer coating one deck colloid at cloth, and the material that often is employed comprises polyisocyanate salt resin (PU), polyethylene (PE), acryl etc.; And lagging material normally is clipped in the interlayer of clothes, with it characteristic of preserving air is arranged, and reaches heat preservation effect, and the material that often is used comprises eider down, chemical fibre cotton class etc.Though the clothes that uses these materials to make has good warming effect, but the clothing of making is often too thick and heavy, therefore existing in recent years people utilizes the principle of material phase change heat absorption, with phase change material (phase-change materials, PCM) add in the textiles, reach heat preservation effect by phase change material.
Phase change material is a kind of material that can absorb or discharge a large amount of heat energy by its physical condition of change, for example, be liquid phase from solid transformation.Typical phase change material can be a liquid phase from solid transformation, also can change solid phase again into from liquid phase.Paraffinic hydrocarbon (paraffin hydrocarbons) often is taken as phase change material and uses, and it can melt in temperature of wanting or higher temperature in heat absorption.
Phase change material is when being heated, can absorb heat energy by the phase change of physics with thermal energy storage in wherein, phase change material can be a liquid phase by solid transformation slowly when continuing to be heated, after avoiding it to become liquid phase, run off, generally by macromolecular material coated phase-change material, make its become micro encapsulation phase change material, because phase change material is coated in the macromolecular material, can make phase change material when heat absorption produces phase change, reason does not become liquid phase and runs off, and can't reuse.
At present phase-change microcapsule has been used on the textile fabric, in No. 5585475 patent of the U.S. (US No:5585475) case, discloses and phase change material is incorporated into blending becomes fiber in the polymkeric substance, with further in order to preparation clothing or bedding.In addition, in No. 5366801 patent of the U.S. (US No:5366801) and No. 6099894 patent of the U.S. (US No:6099894) case, also openly will coat the surface of fiber surface or textiles after phase-change microcapsule and the mixed with polymers, provide the clothes of heat insulation effect with preparation.In addition, in No. 6207738 patent of the U.S. (US No:6207738) case, then open another kind is coated phase change material on the fabric with wet type coating processing mode, produces to have the clothing of holding temp effect.
But above-mentioned these are covered in the known manner of textile surface with phase change material by blending or coating, and are all comparatively loaded down with trivial details on the manufacturing step, and the expenditure that this can cause the puzzlement in the manufacturing and increase manufacturing cost makes the price of this class clothing can not be in any more.Therefore, seek a kind of cheaper manufacture, just become the new direction in the present research and development.
Summary of the invention
The objective of the invention is to sneak in the material with Waterproof Breathable, after film former is with extrusion or blown film mode film forming, to make Waterproof Breathable film with heat insulation function by the phase-change microcapsule that will have heat insulation effect.
Another object of the present invention provides a kind of comparatively easy manufacturing course, to reduce manufacturing cost.
Another purpose of the present invention is to prepare comparatively frivolous and with the clothing of Waterproof Breathable and heat insulation effect by method of the present invention.
For reaching above-mentioned purpose, a kind of Waterproof Breathable film and manufacture method thereof with heat insulation function, wherein this manufacture method can reach by following step.
Select suitable phase change material at first, earlier for use.Then with this phase change material and mixed with polymers to prepare the microcapsule that contain phase change material.
Select suitable Waterproof Breathable material again for use.Afterwards, this Waterproof Breathable material being heated to it dissolves and makes its one-tenth dissolve state again.
Then, the aforementioned phase change material that has a heat-accumulating and-keeping effect through micro encapsulation is sneaked in this water proof and moisture permeable material that dissolves state, make its homodisperse.Afterwards it is cooled to room temperature, this blended liquid macroimolecule is solidified.Again it is ground into the plastic pellet that is mixed with phase-change microcapsule by pulverizer.
At last, with above-mentioned prepared plastic pellet through film former to extrude or blown film, promptly can be made into the plastics film of Waterproof Breathable and heat insulation effect.
Further above-mentioned gained can be cut out with the fabric of Waterproof Breathable and heat insulation effect and can be made with Waterproof Breathable and heat insulation effect and very frivolous clothing.
Wherein, the material that can be used as above-mentioned Waterproof Breathable comprises but is not limited only to thermoplastic polyisocyanate salt resin (TPU), polyethylene and acryl etc.The material that can be used as phase change material in the above-mentioned phase-change microcapsule is in this not special restriction, can decide according to the envrionment temperature in the different purposes and service temperature thereof.The general adducible example of phase change material commonly used comprises materials such as paraffin class carbohydrate straight chain alkanes, higher alcohols, but is not limited only to this.These phase change materials can be made the phase change material of micro encapsulation by known manufacture, further to process and to use.
