[0001] 本发明涉及一种压敏胶带,尤其基材同时拥有多种材料各自特性的胶带。 [0001] The present invention relates to a pressure sensitive adhesive tape, in particular a respective base tape also has a variety of material properties.

背景技术 Background technique

[0002]目前,人们暂时性贴合破漏处使用的压敏胶带主要有基材和粘合剂组成,其中基材大多数为塑料薄膜,主要种类有聚乙烯(PE)、聚丙烯(PP)和聚氨酯(PET)三种。 [0002] Currently, people use temporarily affixed laminated pressure sensitive adhesive tape base material leaking at a main and a binder, wherein the substrate is a plastic film most, the main types of polyethylene (PE), polypropylene (PP ) and polyurethane (PET) three. 但是,以这三种材质为基材的胶带都不能均只有各自本身的特性=PP与PET不易拉伸,不能缓冲压力;PE抗拉强度差,不能承受较大的压力,并且三者对气体、盐类的阻隔性差。 However, these three material for the substrate tape can not both be in their own characteristic = PP and PET stretch easily, not cushion pressure; the PE difference in tensile strength, can not withstand greater pressure, and three gas , salts barrier property is poor. 因此,在一些输送易燃气体、盐溶液的管道,或者海水中若有破漏,使用这些胶带进行快速贴合后都不能有效或者长时间的阻止渗漏,存在安全隐患。 Thus, in some transportation of flammable gas conduit salt solution or seawater leaking if, after use can not be effectively bonded to the adhesive tape fast or long prevent leakage, there are security risks.

发明内容 SUMMARY

[0003] 为了克服现有的压敏胶带特性单一,不能有效或者长时间的堵漏、修补,本发明提供一种压敏胶带,该胶带不仅可以当作普通的压敏胶带使用,而且同时具有多种材料各自的优点,尤其在修补漏洞、破损点时比一般的压敏胶带更有效更长时间的阻止渗漏,更专业用于修补,可称之为修补胶带。 [0003] In order to overcome the conventional single pressure sensitive adhesive tape characteristics, can not effectively plugging or prolonged, repair, the present invention provides a pressure sensitive adhesive tape, the adhesive tape can be only used as an ordinary pressure-sensitive adhesive tape, and also has a variety of materials with their respective advantages, especially in fixing bugs, more effective than the usual pressure sensitive adhesive tape at break point to prevent leakage of the longer, more professional for repair, patching tape can be called.

[0004] 本发明解决其技术问题所采用的技术方案是:首次将多层共挤膜进行电晕处理后用作胶带的基材,粘合剂根据修补的漏洞表面不同选用相应的类型,然后将粘合剂涂在基材电晕面后制成修补胶带。 [0004] aspect of the present invention to solve the technical problem is that: the first coextruded multilayer film as corona treatment of the substrate tape, the adhesive selected according to the respective different types of vulnerabilities patched surface, and the adhesive coated surface of the substrate in the corona Mending tape made. 多层共挤膜主要由聚乙烯(PE)、尼龙(PA)、乙烯-乙烯醇共聚物(EVOH)和钛树脂粘合剂(TIE)等多成分共同组成,其中PE具有拉伸性,PA有良好的抗拉强度和耐冲击力,EVOH具有高阻隔性,由这些材料复合在一起的多层共挤膜同时具备了各成分的优点,是最适合作为修补胶带基材的材料,达到了有效的、长时间的封闭漏洞、破损点的目的。 Coextruded multilayer film consisting essentially of polyethylene (PE), nylon (PA), ethylene - vinyl alcohol copolymer (EVOH) resin binder and titanium (TIE) and other components of the composition together, wherein the PE has stretchability, PA good tensile strength and impact resistance, the EVOH having a high barrier, multilayer coextrusion film composites of these materials together, along with the advantages of each component as a material most suitable for patching tape base material, reaching effective, long closed loopholes, the purpose of breakage points.

[0005] 本发明的有益效果是,可以在方便快捷的封闭漏洞、破损点之处的同时,还能有效并且长时间的防止流动物体渗漏,快捷、简单、有效。 [0005] Advantageous effects of the present invention is that, at the same time can be easily and quickly closed vulnerability, at the point of breakage, but also effectively prevent the flow of the object and a long leakage, fast, simple and effective.

具体实施方式 detailed description

[0010] 在图I中,多层共挤膜胶带的基材(I)由三种或者多种不同特性的材料复合在一起制成拥有各成分优点的多层共挤膜,其中各成分质量所占比重按照使用环境的要求进行调配,例如:需要抗高强度冲击力,则PA含量要高;需要阻隔性能高,则EVOH含量高。 [0010] In Figure I, the multilayer film is co-extruded tape base material (I) made of composite material of different characteristics of three kinds or more together, a multilayer co-extruded film has the advantages of respective components, wherein the components mass be formulated according to the proportion of use of environmental requirements, such as: the need for an anti-impact strength, the PA content is higher; require high barrier properties, the content of EVOH is high. 然后对基材(I)与粘合剂(2)相接处的面进行电晕处理,处理完毕后,再在基材(I)表面复合上粘合剂(2),这样就制成了多层共挤膜胶带。 Then the surface of the substrate contact (I) and a binder (2) subjected to a corona treatment, after processing, and then the substrate (I) on the surface of the composite adhesive (2), was thus prepared coextruded multilayer film tape. 该胶带中的粘合剂(2)要求能与基材⑴与粘合剂⑵接触面及与漏洞表面⑶材质都能紧密相接的粘合剂(2)。 The pressure-sensitive adhesive tapes (2) in claim adhesive (2) with the substrate can ⑴ ⑵ contact surface with the adhesive and the material can close loopholes ⑶ surface contact.

[0011] 在图2所示的实施例中,当有漏洞、破损点(4)出现时,可以方便的使用多层共挤 [0011] In the embodiment illustrated in Figure 2, when there is a loophole breakage point (4) occurs, you can easily use multilayer coextrusion

膜胶带贴合在漏洞、破损点⑷处,粘合剂⑵与漏洞表面⑶紧密贴合,基材⑴也有抗冲击力和高阻隔性,因此有效的阻止了流动物体(5)的泄漏,从而快捷、方便、有效的达到修补漏洞、破损点(4)的目的。 Film tape bonded vulnerability ⑷ damage point, the adhesive surface ⑵ ⑶ with Vulnerability in close contact, the substrate ⑴ impact resistance and also high-barrier, thus effectively preventing the flow of object (5) leakage, thereby fast, convenient, and effective reach to mend fences damaged points (4) purposes.
