本实用新型的目的是设计一种热收缩与热熔融聚合物复合带,这种带的结构特征是由加热时具有纵向收缩性能交联聚烯烃带与加热可熔融流动线性热塑性聚合物,或热熔胶组成的带的复合层及边缘结构,以增加应用的可靠性。应用时将热可熔融层面向被保护部位,1/2～1/3重叠螺旋绕在其外,使胶边处于下一环带之下。这样,在加热外层收缩温度下,边缘胶边与内层开始熔融流动。填充二重叠带间的空间。同时二层熔合为一体、紧缩于被保护部位。
The purpose of this utility model is to design a heat-shrinkable and hot-melt polymer composite tape. The structural feature of this tape is a cross-linked polyolefin tape with longitudinal shrinkage when heated and a linear thermoplastic polymer that can melt and flow when heated, or heat The composite layer and edge structure of the tape composed of melted adhesive to increase the reliability of the application. During application, the heat-meltable layer faces the protected part, and 1/2 to 1/3 overlaps and spirally winds outside it, so that the glue edge is under the next ring. In this way, when the outer layer is heated to shrinkage temperature, the edge rubber edge and the inner layer begin to melt and flow. Fills the space between two overlapping bands. At the same time, the two layers are fused together and tightened on the protected part.
Description
本实用新型属于热收缩与热熔融聚合物双层复合绝缘带的结构设计。The utility model belongs to the structural design of heat-shrinkable and heat-melting polymer double-layer composite insulating tapes.
已有专利95204567.2公开了绕制式复合热收缩带的结构与构像。其产品是由加热纵向收缩聚烯烃的外层与热熔融聚烯烃或热熔胶的内层构成的复合绝缘带。已广泛应用于架空裸线的局部绝缘、汇流母排的密封与防护、破损电缆护层的修复等场合。该产品结构与构像与平带和螺旋定型带比，方便了应用，并提高了应用质量，但依然难免在使用时，重叠层内边缘留下气泡等缺陷，影响其电性能及防护效果。The existing patent 95204567.2 discloses the structure and conformation of the wound-type composite heat-shrinkable tape. Its product is a composite insulating tape composed of an outer layer of heat-shrinkable polyolefin and an inner layer of hot-melt polyolefin or hot-melt adhesive. It has been widely used in the partial insulation of overhead bare wires, the sealing and protection of busbars, the repair of damaged cable sheaths, etc. The structure and conformation of this product are compared with the flat belt and the spiral shaped belt, which facilitates the application and improves the application quality, but it is still unavoidable that bubbles and other defects are left on the inner edge of the overlapping layer during use, which affects its electrical performance and protection effect.
本实用新型的目的是设计一种热收缩与热熔融聚合物复合带，这种带的结构特征是由加热时具有纵向收缩性能交联聚烯烃带与加热可熔融流动线性热塑性聚合物，或热熔胶组成的带的复合层及边缘结构，以增加应用的可靠性。The purpose of this utility model is to design a composite belt of heat-shrinkable and hot-melt polymer. The composite layer and edge structure of the tape composed of melted adhesive to increase the reliability of the application.
本发明同专利95024567.2的区别在于，在热收缩与热熔融二层结构复合带的一边，增加一条内层相同材料构成的胶边结构，胶边和内层材料均在外层加热收缩温度下可熔融流动，起填充间隙，粘结层间的作用。应用时，胶边则足以填充螺旋缠绕重叠层之间的空间，增加热收缩带材的密封可靠性。The difference between the present invention and the patent 95024567.2 is that, on one side of the heat-shrinkable and heat-fused two-layer structure composite belt, a rubber edge structure made of the same inner layer material is added, and both the rubber edge and the inner layer material can be melted at the outer layer heating shrinkage temperature Flow, to fill gaps and bond between layers. When applied, the bead is sufficient to fill the space between the helically wound overlapping layers, increasing the sealing reliability of the heat-shrinkable tape.
本实用新型的实施方案，结合附图描述如下，图一为热收缩与热熔融聚合物双层复合带的横切面示意图，其外层(1)是具有加热纵向收缩交联聚烯烃构成，内层(2)是由线性热塑聚烯烃，或乙烯-醋酸乙烯酯热熔胶或聚酰胺热熔胶构成，外层(1)与内层(2)复合时，内层(2)要宽出外层(1)，形成一胶边。Embodiments of the present utility model are described as follows in conjunction with the accompanying drawings. Fig. 1 is a cross-sectional schematic diagram of a double-layer composite tape of heat-shrinkable and heat-melting polymers. Layer (2) is made of linear thermoplastic polyolefin, or ethylene-vinyl acetate hot-melt adhesive or polyamide hot-melt adhesive. When the outer layer (1) is combined with the inner layer (2), the inner layer (2) should be wider out of the outer layer (1) to form a glue edge.
本实用新型与中国专利95.204567.2公布的热收缩带一样，用于园型导体、母排及异型截面导体绝缘、防水、防盐雾及防护。应用时将热可熔融层面向被保护部位，1/2～1/3重叠螺旋绕在其外，使胶边处于下一环带之下。这样，在加热外层收缩温度下，边缘胶边与内层开始熔融流动。填充二重叠带间的空间。同时二层熔合为一体、紧缩于被保护部位。The utility model is the same as the heat-shrinkable tape disclosed in Chinese patent 95.204567.2, and is used for insulation, waterproof, salt spray prevention and protection of circular conductors, busbars and special-shaped cross-section conductors. When applying, the heat-meltable layer faces the protected part, and 1/2 to 1/3 overlaps and spirally winds outside it, so that the glue edge is under the next ring. In this way, at the shrinkage temperature of the outer layer, the edge glue and the inner layer begin to melt and flow. Fills the space between two overlapping bands. At the same time, the two layers are fused together and tightened on the protected part.
