Abstract

The present invention relates to a kind of sheet material for absorbing impact and sealing comprising adhesive layer.More specifically, it relates to impacts and the sheet material of sealing for absorbing, wherein successively a lamination adhesive layer, one support rete and layer of polyurethane, and relate to the method for this sheet material of preparation.According to according to the present invention for absorb impact and the sheet material of sealing be included in support membrane as substrate laminated on adhesive layer.Therefore, it has relatively high layer of polyurethane thickness within identical sheet thickness.Therefore, when being administered to electronic device, it shows than the better compressibility of the sheet material of lamination two-sided tape on substrate and the better ability absorbing impact and sealing.In addition, preparation in accordance with the present invention, owing to omitting lamination process, has the advantage preparation process of this sheet material being simplified and spillage of material and low bad quality incidence are reduced.

Description

Comprise adhesive layer for absorb impact and sealing sheet material and prepare the method for this sheet material
Technical field
The present invention relates to the sheet material (sheet) for absorbing impact and sealing comprising adhesive layer.More specifically, it relate to wherein the adhesive layer of lamination successively, one support impacting and the sheet material of sealing for absorbing of rete and polyurethane (polyurethane) layer, and relate to the method for this sheet material of preparation.
Background technology
Electronic equipment---such as mobile phone, hard disk drive, TV and liquid crystal display---is made up of the mechanical part of precision and electronic device.Those electronic equipments are easy to break down due to external impact or damage.In addition, from external contaminants such as dust, by upsetting the air-flow in electronic device, causes electronic device overheated.Therefore this shortens electronic device life-span factor.
In order to address these problems, electronic equipment has a sheet material for sealing usually, impacts and a closed gap to absorb.
Such as, Korean patent publication No.2002-0015239 discloses a kind of for maintaining a gap in a liquid crystal display and stopping hot parts.It prevents optical sheet damage or wrinkling by the guide panel (guide-panel) of liquid crystal display, maintains the gap between guide panel and optical plate, and stops that heat and exterior materials flow into this gap.These parts are formed by the liner of silicon materials.In addition, Korean patent publication No.2005-0058055 discloses added elastomeric layer between the substrates, for preventing the gravity defect of liquid crystal display.This selected from polyurethane rubber is formed---comprise vulcabond (aromaticdi-isocyanate), polyalcohol and 1 by coating one deck, 4 butanediols (1, thickener 4-butandiol), then by the slaking on substrate of this thickener.Component or elastic layer disclosed in Korean patent publication No.2002-0015239 and No.2005-0058055, by using silicon or polyurethane, make electric home appliance or electronic device have elasticity and good sealing effectiveness.
But Korean patent publication No.2005-0058055 has trouble part, it needs, after the composite paste material forming elastic layer, to be coated with a pattern in forming process.On the other hand, the advantage that the silicon spacer of Korean patent publication No.2002-0015239 has is, due to its laminated structure, it is easy to be applied to many kinds of electric home appliance or electronic device.Sheet material such as silicon liner is attached to electronic device by placing double-sided adhesive in the one side of this liner, or is attached to electronic device after the one side being coated with this liner with acrylic ester adhesive.But silicon chip material exists its problem come off after being attached to electronic device, because the silicon materials of this liner have low surface tension and have more weak bonding strength for adhesive tape or adhesive.
In order to address this problem, someone attempts silicon liner to be coated with extra priming paint recently.Although this trial can obtain gratifying bonding strength, but it also has problems, the more complicated process such as caused due to the process of increase priming paint coating, the manufacturing cost risen violently, and the environmental problem of the organic solvent comprised in primer base compound.Therefore, people attempt material silicon being used as adhesive or adhesive tape, do not use priming paint with the bonding strength be increased between silicon and adhesive.But this trial not only reduces bonding strength, too increases manufacturing cost.
In addition, also existing people proposes the substitute of polyvinyl chloride (PVC) as silicon.But PVC much higher hard, therefore it needs a large amount of plasticizer to produce elasticity and good sealing.As time goes by, the surface of electronic device easily transferred to by plasticizer, and it pollutes the inner side of device and assembly.Thus it result in the fault of this device and shortens life-span of device.In addition, silicon chip material is by manufacturing the coating of silicon liner with adhesive or at silicon liner upper strata moulding band.Due to the manual pressure step of described process, these processes reduce the manufacturing speed in continuous automated procedure.
In addition, this sheet material tegillum is pressed with double-sided belt and being fixed, with the assembling at this product and the position of applying portion being maintained electronic device between the operating period.But due to the use of double-sided belt, the thickness of whole sheet material increases, if there is thickness to limit, then decreases the thickness of compressible portion.Because reduce the ratio of incompressible material, the compressibility of the requirement of whole sheet material just reduces, and finally can not meet the requirement absorbing and impact and close a gap.In addition, use the process of double-sided belt by increase and cause product material loss and low bad quality incidence to increase, and labor productivity declines.
Summary of the invention
In order to solve described problem, the invention provides a kind of for absorbing the sheet material impacting and seal, it is prepared with the support rete of adhesive layer by using.Therefore, The present invention reduces the adhesive layer being administered to this sheet material in addition and the quantity supporting rete, and add the relative thickness with high compressible layer of polyurethane.Therefore, present invention achieves for the preparation of absorbing the sheet material impacting and seal, this sheet material shows the ability that higher absorption is impacted and sealed, and has the manufacture process of simplification.
Therefore, an aspect of of the present present invention is to be provided for absorb impacts and the sheet material of sealing, and it comprises one and supports rete, and this support rete comprises an adhesive layer and one for absorbing the froth bed of impact.
Another aspect of the present invention is to provide a kind ofly to be prepared this and impacts and the method for sheet material of sealing for absorbing.
