Abstract

The invention discloses a preparation method of insulated rubber, relating to the technical field of rubber. The insulated rubber is prepared from the following raw materials in parts by weight: 100 parts of rubber, 2-10 parts of an active agent, 2-10 parts of an accelerant, 2-10 parts of an anti-aging agent, 30-80 parts of a filling agent, 3-15 parts of a softener and 12-15 parts of a curing agent. The preparation method comprises the steps of A, sequentially adding the rubber, the active agent, the accelerant, the anti-aging agent and the filling agent into an internal mixer to mix for the first time at the temperature of 50-60 DEG C for 60-65 seconds; B, adding the softener into the internal mixer to mix for the second time at the temperature of lower than 105 DEG C for 75 seconds, then, cooling and discharging rubber; and C, curing, namely discharging the rubber obtained in the step B onto a tablet pressing machine, then, adding the curing agent to smelt in an overturned way for 120 seconds, and discharging tablets to obtain the insulated rubber. By using the preparation method, the problems of short service life, poor heat resistance, poor oil resistance, poor ozone resistance and low tensile strength of the existing rubber are solved.

Description

Electro-insulating rubber preparation method
Technical field
The present invention relates to field of rubber technology, especially a kind of electro-insulating rubber preparation method.
Background technology
In power system, electrician usually needs live line work, for the danger avoiding staff to have electric shock in the course of the work, people are set with the rubber with insulativity on the handle of electrician's used tool, but it is short that this type of current rubber usually runs into work-ing life, the problems such as heat-resisting, oil resistant, resistance to ozone, tensile strength are low, therefore provide one to have long service life, what heat-resisting, oil resistant, resistance to ozone, tensile strength were high have comfortable feel and the rubber with high-insulativity is the problem that those skilled in the art need solution badly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of electro-insulating rubber preparation method, it can solve, and existing rubber is short for work-ing life, heat-resisting, oil resistant, resistance to ozone, problem that tensile strength is low.
In order to solve the problem, technical scheme of the present invention is: this electro-insulating rubber preparation method, adopts the raw material of following weight part:
Rubber: 100 parts; Promoting agent: 2 parts to 10 parts; Promotor: 2 parts to 10 parts; Anti-aging agent: 2 parts to 10 parts; Weighting agent: 30 parts to 80 parts; Tenderizer: 3 parts to 15 parts; Vulcanizing agent: 12 parts to 15 parts;
Comprise the steps:
A. in Banbury mixer, add described rubber, promoting agent, promotor, anti-aging agent and weighting agent successively, then starting Banbury mixer, to carry out first time mixing, and 60 seconds to 65 seconds time, temperature is 50 DEG C to 60 DEG C;
B. in the Banbury mixer of step A, adding tenderizer, to carry out second time mixing, and 75 seconds time, temperature is less than 105 DEG C, then cools binder removal;
C. sulfuration: the glue of step B is discharged to and tabletting machine adds vulcanizing agent again turns refining, 120 seconds time, bottom sheet and get final product.
In technique scheme, scheme can also be more specifically: described rubber is urethanes and isoprene-isobutylene rubber, and the weight ratio of urethanes and isoprene-isobutylene rubber is 2: 8.
Further: described promoting agent is zinc oxide, described promotor is dithiocar-bamate; Described anti-aging agent is Ursol D anti-aging agent; Described weighting agent is nanoclay; Described tenderizer is paraffin; Described vulcanizing agent is curing resin.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, owing to have employed urethanes and isoprene-isobutylene rubber, and the weight ratio of urethanes and isoprene-isobutylene rubber is 2: 8; Make the rubber synthesized not only have good electrical insulating property, resistance to ozone, ageing-resistant, thermotolerance, and tool have good wearability, oil-proofness and high strength, snappiness.
2, sulfiding process temperature of the present invention is low, curing time is short, make rubber become the macromole of tridimensional network by the macromolecules cross-linking of linear structure, its anti-tensile of the rubber of output, surely stretch, wear-resisting performance is good.
