Self-adhesion, high strength and high-temperature resistant nylon composite film for waterproof coiled materials and machining method thereof

一种防水卷材用自粘强力耐高温尼龙复合膜及其加工方法

Abstract

The invention discloses a self-adhesion, high strength and high-temperature resistant nylon composite film for waterproof coiled materials. The self-adhesion, high strength and high-temperature resistant nylon composite film is characterized by comprising a five-layer structure which comprises a PIB (Polyisobutylene) self-adhesion layer, a first adhesive layer, a nylon reinforcement layer, a second adhesive layer and a printing layer in turn. The self-adhesion, high strength and high-temperature resistant nylon composite film is blown out through a five-layer co-extrusion down blowing machine, new devices do not need to be invested, and the original device needs to be modified only; the effective balance of the adhering strength and the stripping strength is achieved, the packaging is rapid, the adhering fastness is large, a special welding machine is not required, the self-adhesion, high strength and high-temperature resistant nylon composite film is attached to the back side of the coiled materials, and the packaging on the coiled materials is achieved through the self-viscidity; the packaging is convenient, the effort is saved, and the manpower and material resources are saved.
本发明公开了一种防水卷材用自粘强力耐高温尼龙复合膜,其特征在于所述复合膜包括五层结构,所述五层结构依次为PIB自粘层、第一粘合剂层、尼龙增强层、第二粘合剂层和印刷层。本发明用五层共挤下吹机挤出防水卷材用自粘强力耐高温尼龙复合膜,不需投入新设备,原有设备改造即可;自粘强力耐高温尼龙复合膜作到贴合强度和剥离强度的有效平衡,既作到包装快捷,贴合牢度大,不需专用热合机,膜附在卷材后,用自身的粘性完成对卷材的包装;包装方便,省力,节约人力物力。
