Title:
SEMI-STEEL BASE RUBBER MATERIAL USING CARBON NANO TUBE COMPOSITE MASTERBATCH AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/073489
Kind Code:
A1
Abstract:
The present invention relates to a semi-steel base rubber material using a carbon nano tube composite masterbatch and a preparation method therefor. The rubber material is prepared from the following raw materials in parts by weight: 50-100 parts of a natural rubber, 20-50 parts of carbon black with a high specific surface area and a high structure, and 1-55 parts of a carbon nanotube compound. The preparation method comprises the following steps: uniformly dispersing the carbon nanotube compound into the natural rubber in advance at a certain ratio, and adding same to an internal mixer for plasticization for 20-40 seconds; then adding carbon black, an anti-aging agent, zinc oxide and stearic acid for mixing, heating same and controlling the temperature to be 150-165ºC, and discharging the rubber to form the masterbatch; and after leaving to stand, adding sulfur and an accelerant, and raising the temperature and controlling the temperature to be 95-105ºC for rubber discharging, so as to form the semi-steel base rubber material. The base rubber disclosed by the invention has a high conductivity and a low rolling resistance.
