Embodiment 1

[0045] Example 1: figure 1 , figure 2An example of an insulation blanket composed of 5 rubber sheets is given. The thickness of each rubber sheet 2 is 0.7mm±0.2mm. Five rubber sheets are superimposed on a semi-finished product with a thickness of 3.7mm, and the semi-finished product is put into the mold. Then it is vulcanized by a flat vulcanizer, and the reinforcement edge 1 is formed by pressing the surrounding sides of the vulcanization; the width of the reinforcement edge 1 around the insulation blanket is 6mm, and the reinforcement edge 1 and the overall insulation blanket are both planar structures (the existing multi-layer rubber composite insulation blanket The edge is 6mm wide and 8mm thick, and the edge is higher than the overall insulation blanket. The maximum width of the arc on the edge is 16mm, and the thickness is 8mm, that is, the arc is higher than the edge). Compared with existing products, the peripheral structure of the insulating blanket is obviously sim...

Abstract

The invention relates to a multilayer composite insulation carpet for hot-line work and a preparation method for the multilayer composite insulation carpet. The preparation method comprises the following steps: adding preparations, such as an aging agent and a fire retardant, are added into natural rubber or ethylene-propylene-diene terpolymer to obtain a mixture according to requirements of operation fields with different voltage levels; carrying out banburying, rubber filtering and mixing on the mixture to prepare rubber sheets which are 0.3-1.5mm thick; stacking 3-8 rubber sheets and putting into a mold; and vulcanizing the rubber sheets through a flat plate vulcanization machine, and laminating the peripheries of the rubber sheets to form an integrated reinforcement edge, wherein the composite thickness of the insulation carpet is 2.0-4.5mm; the reinforcement edge is 6mm wide; the reinforcement edge and the integrated insulation carpet are planes. Compared with the prior art, the multilayer composite insulation carpet has the advantages that the peripheral structure of the insulation carpet is obviously simplified, so that the problem of low flexibility, caused by a complicated edge structure, of an insulation carpet product is solved, and the defects of low flame retardant performance, low multi-layer weather resistance and aging resistance and the like are overcome; meanwhile, the product has the advantages of simple structure, convenience in manufacturing, high product flexibility, high flame retardant performance, high rear-aging resistance and the like.

Description

technical field [0001] The invention relates to a rubber insulation blanket, in particular to a multi-layer rubber composite insulation blanket for live work and a preparation method thereof. Background technique [0002] As we all know, at present, when installing or overhauling wiring circuits and power equipment, in order to prevent unintentional contact with electrified parts during live work, and at the same time, in order to prevent short circuit of live equipment and human body from electric shock, the traditional rubber insulation blanket used is generally a single Layer, single-layer rubber blanket feels heavy when used, especially when working at heights, it is easy to slide. At present, in the research and development of multi-layer rubber composite insulation blanket products (the application number is CN201320483457 has obtained the patent right and the invention patent application with application number CN201310344371 is the same applicant as this application)...
