Busbar heat shrinkable sleeve pipe masterbatch formula

Abstract

The invention discloses a busbar heat shrinkable sleeve pipe masterbatch formula, and belongs to the technical field of busbar heat shrinkable pipes. The component of the busbar heat shrinkable sleevepipe masterbatch formula comprises ethylene propylene diene methylene, EVA, PE, aluminum powder, environment-friendly decabromine, environment-friendly antimony oxide, zinc stearate, an antioxidant,a special wax and color masterbatch, and the component further comprises a stabilizer, an antibacterial agent and a reinforcing fiber. Chemical corrosion resistance and impact elasticity of a busbar heat shrinkable pipe are improved through excellent chemical stability of ethylene propylene diene methylene, EVA and PE, the viscosity of a mixed material is improved through EVA, flame retardant performance of the busbar heat shrinkable pipe is improved through excellent thermal stability of environment-friendly decabromine and environment-friendly antimony oxide, the softening property of othercomponents is reduced by zinc stearate, and thus all the components can be well mixed, and an oxidation process of the busbar heat shrinkable pipe is retarded or inhibited through the antioxidant, sothat the service life of the usbar heat shrinkable pipe is improved. The prepared heat-shrinkable pipe has stable physical and chemical properties, and chemical corrosion resistance is improved, so that popularization and application are convenient.

Description

technical field [0001] The invention relates to the technical field of heat-shrinkable tubes for busbars, in particular to a masterbatch formula for heat-shrinkable tubes for busbars. Background technique [0002] The full name of masterbatch is plastic masterbatch, also known as masterbatch. It is a plastic processing aid developed in the 1980s. It is composed of excess chemical additives, carrier resin and dispersant. Masterbatch is the The aggregate obtained by uniformly loading super-normal pigments or dyes in the resin. For the convenience of operation, the required various additives, fillers and a small amount of carrier resin are first mixed and kneaded, and then passed through extruders and other equipment. The granules produced by metering, mixing, melting, extrusion, pelletizing and other processes are called masterbatches. The masterbatch is composed of carrier resin, various fillers and various additives. The limit of additives in the masterbatch or The content ...

[0003] The heat-shrinkable busbar protective sleeve is made of special polyolefin after special processing, which has extremely high insulation performance. The heat-shrinkable busbar protective sleeve is divided into 1KV heat-shrinkable busbar protective sleeve and 10KV heat-shrinkable busbar protective sleeve. , 35KV heat-shrinkable busbar protective sleeves, heat-shrinkable busbar protective sleeves are used for insulation protection of substation busbars, high-voltage and low-voltage switchgear busbars, which can make the structure of the switchgear compact, shorten the distance between phases, and prevent occasional short-circuit accidents , but the existing busbar heat-shrinkable tubes have poor chemical corrosion resistance and short service life, and have not been well promoted
