Rate.
In order to keep technical purpose of the invention, technical solution and technical effect apparent, in order to art technology
Personnel understand and implement the present invention, and the present invention will be further described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The invention proposes a kind of preparation methods of silica gel cable, comprising the following steps:
Step S1, preformed layer is formed outside core；The preformed layer includes silica gel；
Specifically, in this step, preformed layer further includes coloring agent, A agent and B agent；Wherein, A agent is for reducing viscosity, B agent
For agglomerating.Specifically, A agent is platinum catalyst；B agent is platinum crosslinking agent.The raw material of preformed layer is kneaded by kneading machine, is obtained
To prefabricated material；Prefabricated material is wrapped in outside core by extruder, to form preformed layer.
Step S2, over oil treatment is carried out to preformed layer, to colour to preformed layer；
In this step, by carrying out over oil treatment to preformed layer, to adhere to silicone resin outside preformed layer；
Step S3, the preformed layer after coloring is vulcanized, to fix the color of preformed layer；Then, it is fixed in color
It is wrapped to form silicone layer again outside preformed layer, to obtain silica gel cable.
In this step, the sulfidation of the preformed layer after coloring can be divided into vulcanization induction, pre- sulphur, optimum cure and over cure four
A stage.Wherein, in vulcanization induction period, crosslinking not yet starts, and sizing material has good mobility；This stage determines sizing material
Incipient scorch and process safety.Vulcanize the length of induction period except related with rubber vulcanization nature, additionally depends on used
Auxiliary agent such as uses the available longer time of scorch of persistent accelerator, and has higher process safety.Later, can enter
In the presulfurization stage, sizing material starts crosslinking and lost flowability at this time.The crosslinking degree of sizing material is low in this stage, and vulcanizate pulls
Disconnected intensity, elasticity can not reach anticipation level, but tear and when the performance of dynamic breach is than the corresponding optimum cure stage
It is good.After entering the optimum cure stage, the physical properties of vulcanizate respectively reach or close to Best Points, or reach the comprehensive of performance
Full balance.In the over cure stage, if crosslinking is still dominant, vulcanizate will harden, and stretching strength, which continues to rise, completes vulcanization,
And preformed layer color is fixed.Herein, in the sulfidation of the preformed layer after coloring, silicone resin will not be sent out with vulcanizing agent
Raw reaction.
