Description
Technical field
The self-priming closure magnetic stripe and preparation method thereof that the present invention relates to a kind of for flexible door curtain.
Background technology
The utilization of magnetic self-suction flexible door curtain is more and more extensive, is chiefly used in the public arenas such as market, dining room, workshop, also uses
In household, have the functions such as windproof, dust-proof, mosquito-proof, transparent, decoration, self-priming closure, increasingly by the blueness of ornament materials circle
It looks at.
Since the difference of magnetic mode exists, all various deficiencies need the magnetic self-suction flexible door curtain of the prior art
It improves.
Authorization Notice No. 2802053Y discloses a kind of rubber magnetic strip type whole closed soft screen door, the overlapping on two width door sides
Place is equipped with rubber magnet strip of paper used for sealing, and the ferrite sintered magnetic patch of relatively high magnetism is equipped in the lower end of strip of paper used for sealing.Its shortcoming is door seal
Overlapping, screen door thickness can be increased, influence decorative effect, ferrite sintered piece, local suction is strong, brings the endless of usage experience
Security risk at beautiful and strong suction.The obvious patent is adsorbed using the front-back overlapping of rubber seal strip, to ensure enough suctions
Power but brings thickness increase, the drawbacks such as too fat to move.
Authorization Notice No. 101731928B, magnetic catch type transparent film curtain disclose commissure device number row's magnetic and touch dress
It sets, there is stripe shape magnetic patch, outside to use cushion compound bound edge in crash device.The shortcoming of this patent is inhaled by local magnetic force
Attached, the magnetic block for generating local suction certainly exists security risk, and suction is unevenly distributed, and user experience uses inevitable not complete enough
U.S., sealing effect can not also ensure.
Authorization Notice No. 2272713Y, a kind of door curtain, the strip soft material that it is vertically hung by several are constituted, special
Sign is that the transverse sides in strip soft material are respectively equipped with vertical tubule, and two tubules are respectively filled with silicon materials and magnetic material
Material can not therefrom be obtained and magnetic suck may be implemented, can not also be obtained other suction types due to two tube materials difference, it is seen that
The firmness of self-priming is no collateral security, and this patent does not carry out the disclosure of related suction.
The final effect parameter that suction F can intuitively embody when being magnet use, F ∝ Bg*Bg*S, suction are proportional to
Square of the magnetic flux density Bg in the magnetic circuit gap that magnet and absorbate matter are formed, suction size is directly proportional to adsorption area, conventional
The working face of magnetic stripe all designs the one side larger in magnetic stripe area, and the small side of area is not usually in the range of consideration.This
Applicant's Authorization Notice No. 104945754B discloses a kind of manufacturing method for the rubber extruding magnetic stripe improving suction：Magnetic stripe passes through
Co-extrusion is integrally formed, at least double-layer structure, and one layer is conventional magnetic layer, and in addition one layer is soft magnetosphere, and suction improves 15-
30%, but the patent does not disclose the selection of the working face of magnetic stripe further, the matching to the mode of magnetizing and working face
Also it does not disclose further.
The big working face of area is abandoned, the small side of conversion suction is perverse, moreover must increase the thickness of side,
This brings the difficulty for being difficult to overcome to magnetic stripe production technology, and magnetic stripe is too thick to be difficult to cut, and yield rate is low, and the production of magnetic stripe can not
Upper amount, production cost are high.
The present invention program will solve deficiency in the prior art：To ensure that side has enough suction, magnetic stripe thickness that need to reach
To 5mm, slitting is difficult, and yield rate is low, it is difficult to upper amount；Suction is by the offer of magnetic stripe part, edge seal discontinuity, part
There are security risks at strong suction；Magnetic attracting device front-back overlapping absorption, adsorption plane are far longer than side, too fat to move, influence door curtain
Utility function and decoration functions.
