Abstract

The invention discloses a rubber composite material for a wire protective sleeve and a manufacturing method of the rubber composite material and belongs to the technical field of material science. The rubber composite material comprises main components, fillers and the manufacturing method of the rubber composite material; the main components include the following substances in percentage by weight based on standard substances thereof: 25wt% to 27wt% of butadiene-styrene rubber, 22wt% to 24wt% of natural rubber, 5wt% to 6wt% of the paraffin and 1wt% to 1.5wt% of a stabilizing agent; the fillers include 2wt% to 3wt% of zinc oxide, 27wt% to 30wt% of magnesium oxide and 15wt% to 20wt% of calcium carbonate; in order to enable the components of the materials to be more uniform during a mixing process, the various materials are added according to a sequence as follows: the magnesium oxide, the natural rubber, the zinc oxide, the butadiene-styrene rubber, the paraffin, the stabilizing agent and the calcium carbonate; a wire prepared from the wire protective sleeve rubber material has the advantage of preventing cracking caused by ageing of the protective sleeve material so as not to affect the safety.

Description

A kind of trunking rubber composite and manufacture method
Technical field:
The present invention relates to a kind of trunking elastomeric material, can prevent with the electric wire of this trunking elastomeric material manufacture that sheath material is aging to be occurred slight crack and affect safety.
Background technology:
The trunking elastomeric material that existing electric wire production industry is used, under being subject to sunlit situation, there is slight crack in the jacket rubber material easily aging rubber sleeve material that causes, the expansion along with slight crack makes electrical conductor be exposed to outside, thus forms potential safety hazard.
Summary of the invention:
The object of this invention is to provide a kind of performance and prevent aging trunking elastomeric material.
Another object of the present invention is to provide the preparation method of trunking elastomeric material.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs:
It comprises main composition and weighting material and manufacture method thereof, and described principal constituent is butadiene-styrene rubber, natural gum, paraffin, stablizer; Described weighting material is: zinc oxide, magnesium oxide and calcium carbonate; Described main composition in the weight percentage of respective standard substance is: butadiene-styrene rubber is 25-27wt%; Natural gum is 22-24wt%; Paraffin is 5-6wt%; Stablizer is 1-1.5wt%; Described weighting material zinc oxide is 2-3wt%; Magnesium oxide is 27-30wt%; Calcium carbonate is 15-20wt%; In order to make material composition in mixing process more even, the order of addition of various material is: magnesium oxide, natural gum, zinc oxide, butadiene-styrene rubber, paraffin, stablizer, calcium carbonate.
The trunking elastomeric material adding manufacture in the process of principal constituent of the present invention and weighting material batching in the following order effectively can extend digestion time: magnesium oxide, natural gum, zinc oxide, butadiene-styrene rubber, paraffin, stablizer, calcium carbonate.
Applicant finds, adds magnesium oxide and replaces part calcium carbonate and whole talcum powder effectively can play the aging function preventing elastomeric material.
Applicant finds, it is the most desirable to add effect when magnesium oxide replaces part calcium carbonate and whole talcous ratio by mass percentages to reach 27%.
Remaining steps characteristic of the present invention all can adopt rubber manufacturing process, and these are all well known to those of ordinary skill in the art.
Below in conjunction with embodiment, further detailed description is done to technical scheme of the present invention,
But; be noted that: the citing of following embodiment just to technical solution of the present invention; it is not limitation of the present invention; those of ordinary skill in the art when after having read this specification sheets according to its knowledge grasped when not making creative work; various accommodation can be made, as long as but all by being protected within the scope of the claims in the present invention to following embodiment.
