CN103101122A - Conductive aggregate blending method - Google Patents

Abstract

The invention provides a conductive aggregate blending method comprising the following steps of: a. adjusting the distance between two blending rollers of a blending machine to be 4+/-0.3mm, repeatedly blending for 4-6 times, and adding a bridging agent simultaneously; b. adjusting the distance between the two blending rollers of the blending machine to be 3+/-0.3mm, and repeatedly blending for 18-20 times; and c. detecting the rigidity of a blended mixed material; if the rigidity value is more than or equal to 55 degrees, standing the treated material for 72-96 hours and completing the blending process; and if the rigidity value is less than 55 degrees, standing the treated material for 4-72 hours, and completing the blending process. The conductive aggregate blending method disclosed by the invention has the advantages of uniform blending and mixing, good dispersibility and good mechanical properties such as stretching strength, tensile strength, and elongation at failure.

Description

A kind of conductive granule compounding process

Technical field

The present invention relates to a kind of improvement of rubber mass mixing technology.

Background technology

Mixing is first operation in the rubber processing process, and this operation generally adopts banbury to complete.Existing mixing operation all is complexity, and the rubber mass after mixing is second-rate, is difficult to meet the subsequent production processing request.

Summary of the invention

In view of this, the technical problem to be solved in the present invention provides a kind of melting effect good conductive granule compounding process.

In order to solve the problems of the technologies described above, the present invention adopts following scheme to realize:

A kind of conductive granule compounding process, the method comprises the steps:

A. the spacing of adjusting between the mixing roller of mixing roll two is 4 ± 0.3mm, mixing 4～6 times repeatedly, adds simultaneously bridging agent;

B. the spacing of adjusting between the mixing roller of mixing roll two is 3 ± 0.3mm, mixing 18～20 times repeatedly;

C. detect the batch mixing hardness after mixing, if hardness more than or equal to 55 degree, standing 72～96 hours, mixing operation was completed; If hardness is less than 55 degree, standing 4～72 hours, mixing operation was completed.

Disclosed mixing the mixing of conductive granule compounding process, good dispersion has the mechanical properties such as good stretching strength, hot strength, elongation at break.

The specific embodiment

For the ease of it will be appreciated by those skilled in the art that below in conjunction with embodiment, the present invention is described in further detail:

A kind of conductive granule compounding process, the method comprises the steps:

A. the spacing of adjusting between the mixing roller of mixing roll two is 4 ± 0.3mm, mixing 4～6 times repeatedly, adds simultaneously bridging agent;

B. the spacing of adjusting between the mixing roller of mixing roll two is 3 ± 0.3mm, mixing 18～20 times repeatedly;

C. detect the batch mixing hardness after mixing, if hardness more than or equal to 55 degree, standing 72～96 hours, mixing operation was completed; If hardness is less than 55 degree, standing 4～72 hours, mixing operation was completed.

In the present embodiment, the spacing in a step can be 3.7mm or 4mm or 4.3mm, and mixing number of times can be 4 times or 5 times or 6 times, spacing in the b step can be 2.7mm or 3mm or 3,3mm, mixing number of times can be 18 times or 19 times or 20 times, and above-mentioned data value all can reach objects of the present invention.

Disclosed mixing the mixing of conductive granule compounding process, good dispersion has the mechanical properties such as good stretching strength, hot strength, elongation at break.

Above-described embodiment is only wherein specific implementation of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these apparent replacement forms all belong to protection scope of the present invention.
