Problems solved by technology

[0002] The skeleton material of the heat-resistant conveyor belt used in the steel mills is polyester canvas, but the heat resistance of the polyester canvas itself is very poor, and it can melt at 260°C
The working environment of the conveyor belt is generally high, so the skeleton material of the conveyor belt becomes brittle and loses strength in such a working environment, which affects the service life of the conveyor belt
[0003] The base material of the current cover rubber is EPDM rubber, but the adhesion performance of EPDM rubber is very poor. Working in a high temperature environment for a long time will cause the cover rubber of the conveyor belt to delaminate from the buffer rubber and adhesive glue in the middle. So it can't play the role of protecting the skeleton material

Abstract

The invention relates to a preparation method of high heat-resisting cover glue for conveying materials, comprising the following processing steps of: (1) mixing: mixing thylene propylene rubber A with thylene propylene rubber B in an internal mixer; then adding zinc oxide, magnesium oxide, antiager RD and antiager MB, then adding carbon black and paraffin oil for mixing, and discharging the glue; (2) placing the glue obtained from the glue discharging process at the room temperature for 10-12h and then performing two-section mixing, in the first-section mixing, charging the glue into the internal mixer to obtain mixed glue, and in the section-section mixing, adding zinc oxide, a vulcanizing agent and a cross-linking agent and then mixing for 80-90s at a temperature of 90-100 DEG C; and discharging the glue; and (3) extruding pieces: extruding the glues discharged from the two-section mixing process into pieces on an extruder to obtain the high heat-resisting cover glue. The invention prolongs the service life of a conveyer belt and can be adaptive to the serious environment of high temperature in sintering plants of steel mills together with the adhesive force and burn-resisting capability of steel mesh glue.

Description

technical field [0001] The invention relates to a preparation method of a high-heat-resistant covering glue for conveying materials, in particular to a high-heat-resistant covering glue used for conveying materials in a sintering workshop of a steel factory.

The working environment of the conveyor belt is generally high, so the skeleton material of the conveyor belt becomes brittle and loses its strength under such a working environment, which affects the service life of the conveyor belt. [0003] The base material of the current cover rubber is EPDM rubber, but the adhesion performance of EPDM rubber is very poor. Working in a high temperature environment for a long time will cause the cover rubber of the conveyor belt to delaminate from the buffer...
