Description
Technical field
The utility model belongs to amenities technical field, and in particular to a kind of water proofing property three-layer type breathable films.
Background technology
In the every field of human lives, breathable films contain the inorganics filled thing of the ultra-fine density of vast scale, through excessively stream
Prolong after the processing of micro-embossed drawing process, form micropore, the density of micropore distribution is big so that breathable films have higher moisture-inhibiting
Amount, a ventilation body, without leak fluid, is a kind of new material developed rapidly in the world, referred to as the film that can be breathed,
Because of the every field that it has ventilative and fluid-tight characteristic and is widely used in the mankind.Such as personal care field, textile clothing
The field such as field, medicine and hygiene fieldses, agriculture field, packaging for foodstuff and other building, packaging, outdoor equipments.
Existing breathable films, are mixed by the calcium carbonate particle and polyethylene material of 0.5 micron~10 microns of diameter, passed through
Extruder extrusion, stretching are formed, and calcium carbonate particle is irregular to be distributed in PE films.Because calcium carbonate particle does not possess extension
Property, therefore in stretching, PE films are thinning, and a fixed gap can be formed between calcium carbonate particle and PE films, exactly because this space,
Breathable films are breathed freely but waterproof, but if continuing to stretch, when thin to 15 microns~20 microns of breathable films, portion
Point calcium carbonate particle can protrude from former PE films surface, and ventilation space will expand therewith, space greatly to a certain extent after,
Then breathable films are possible to permeable, or even can make breathable films situations such as occurring fracture, junk during stretching.
Utility model content
The utility model purpose is：A kind of water proofing property three-layer type breathable films are aimed to provide, with firmly not fragile, waterproof
Property is good, good anti-bacterial effect the advantages of, and the requirement of permeable watertight can be met, be highly suitable to be applied among amenities.
To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
Pasted with middle level upper surface on a kind of water proofing property three-layer type breathable films, including the upper, middle and lower, the upper strata
Close, the lower floor fits with middle level lower surface, and the upper, middle and lower are PE layers, brokenly divides in the middle level
Calcium carbonate particle is furnished with, the upper strata upper surface is fitted with antibiotic layer.
Using the utility model of the technical program, production technology is as follows：
1st, raw material prepares：Raw material I：Polyethylene+calcium carbonate；Raw material II：Polyethylene；Raw material III：Polyethylene+Nano Silver；
2nd, raw material I and raw material III are stirred 15 points of kinds by agitator with 60 turns per minute of speed, it is ensured that well mixed；
3rd, the raw material I after stirring is sent into A screw rods and is melted raw material with the temperature of 180 degree~230 degree by feed system, by original
Material II is sent into B screw rods and is melted raw material with the temperature of 180 degree~230 degree, and raw material III is made a gift to someone into C screw rods with 180 degree~230 degree
Temperature melts raw material；
The raw material I of 4 and then A screw rods squeezes into distributor through center-aisle, and the raw material II of B screw rods is squeezed through the right and left passage
Enter distributor, the raw materials III of C screw rods squeezes into distributor through Far Left passage, distributor is by BABC arrangement mode by raw material I, former
Material II and raw material III are cooled and shaped respectively by die head film extrusion through cooling system；
5th, calibrator on-line checking, and by data feedback to tensioning system, tensioning system according to thickness adjust automatically parameter,
By film stretching to setting thickness；
6th, winding system is wound.
The extruded machine of the breathable films is processed and formed at one time, without bonding, and breathable films are after extrusion molding, calcium carbonate grain
Son 5 is randomly distributed in middle level 2, and after stretching, film body is thinning, the void enlargement between the calcium carbonate particle and PE films in middle level,
The calcium carbonate particle in middle level penetrates middle level and enters the upper and lower simultaneously, forms air-vent between the upper and lower, but because
The upper and lower are originally without calcium carbonate particle, even if film body is thinning, are also not in that air-vent change causes what film body was broken greatly
Situation, antibiotic layer can play antibacterial functions, protect the health of user.Such structure design, with firmly not fragile, waterproof
Property is good, good anti-bacterial effect the advantages of, and the requirement of permeable watertight can be met, be highly suitable to be applied among amenities.
Further limit, the antibiotic layer is nanometer silver antimicrobial layer.Such structure design, bactericidal effect is good, effect is held
Long.
Further limit, the thickness of the antibiotic layer is 3 μm~7 μm.Such structure design, with preferably killing
Bacterium effect.
Further limit, the thickness of the upper and lower is 1 μm~5 μm.Such structure design, with more
Good air permeable waterproof effect.
Further limit, the thickness in the middle level is 3 μm~11 μm.Such structure design, fastness is good, is difficult
Pull open.
Brief description of the drawings
The nonlimiting examples that the utility model can be provided by accompanying drawing are further illustrated；
Fig. 1 is a kind of section structure schematic diagram of water proofing property three-layer type breathable films embodiment of the utility model；
Main element symbol description is as follows：
Upper strata 1, middle level 2, lower floor 3, antibiotic layer 4, calcium carbonate particle 5.
Embodiment
In order that the utility model may be better understood in those skilled in the art, it is right with reference to the accompanying drawings and examples
Technical solutions of the utility model are further illustrated.
As shown in figure 1, a kind of water proofing property three-layer type breathable films of the present utility model, including upper strata 1, middle level 2 and lower floor
3, upper strata 1 is fitted with the upper surface of middle level 2, and lower floor 3 fits with the lower surface of middle level 2, and upper strata 1, middle level 2 and lower floor 3 are PE layers, in
Calcium carbonate particle 5 is brokenly distributed with layer 2, the upper surface of upper strata 1 is fitted with antibiotic layer 4.
In the present embodiment, production technology is as follows：
1st, raw material prepares：Raw material I：Polyethylene+calcium carbonate；Raw material II：Polyethylene；Raw material III：Polyethylene+Nano Silver；
