Electric wire and cable plastic

Abstract

The invention discloses an electric wire and cable plastic, which is composed of the following components in parts by weight: 30-60 parts of polyvinyl chloride resin, 6-10 parts of epoxy resin, 5-12 parts of stearic acid, 3-8 parts of quartz powder, 8-10 parts of flame retardant, 5-10 parts of zinc oxide, 2-5 parts of electrical insulating modifier, and 3-5 parts of lubricant. According to the invention, a situation that a good surface of the plastic is still kept at a high-speed machining speed of above 600-800 m / min in automotive wire production fields is guaranteed, and the surfaces of wires have no coarse phenomenon; and furthermore, through adding a calcium-zinc compound stabilizer at 105 DEG C to cooperate with an antioxidant, the heat resistance of an insulating material at 105 DEG C can be enhanced well.

Description

technical field

[0001] The invention relates to an insulating layer of electric wire and cable for automobiles, in particular to a plastic for electric wire and cable. Background technique

[0002] Usually, the production method of polyvinyl chloride cable materials for automobile wires is based on polyvinyl chloride resin, adding plasticizers, stabilizers and processing aids, and processed by special mixing equipment, although it can meet the basic needs of automobile line production , but there are problems of strong odor, poor scraping performance and unsatisfactory processing performance. Due to the special use position of the automobile wire, the mutual friction between the wire and the wire cannot be avoided during the operation of the automobile. Once the plastic sheath is worn out, it will directly lead to a short circuit and cause traffic accidents. In addition, the car compartment is a relatively closed space. The supporting items used in the compartment must be e...
