Embodiment 1

[0018] Using the natural staphilite ore of Guangxi resources as raw material, the raw ore is washed, crushed and processed to 80-120 mesh; with 60 grams of staphite, 5 grams of zinc oxide, 2 grams of stearic acid, 2.3 grams of sulfur, and 0.8 grams of accelerator gram, 100 grams of rubber, put the natural rubber on the plastic refining machine for initial refining, then add zinc oxide, accelerator, sulfur, and other additives in turn and mix well, then add hematite several times, and mix the rubber until the rubber After the upper and lower surfaces are relatively smooth, take the glue, place it on a clean glass plate, cut it into 22.5×10 (mm) thin slices, take it to a plate vulcanizing machine for vulcanization, and then preheat it with soapy water Put the cut film into the finished mold, pressurize and vulcanize, control the vulcanization temperature within the range of 140°C, and vulcanize for 20 minutes. After the vulcanization is completed, take the glue, cut the vulcanize...

Abstract

A process for preparing the reinforcing agent of rubber from redglow zeolite includes such steps as washing, pulverizing, proportionally mixing it with zinc oxide, stearic acid sulfur, promoter and rubber, neutralizing, adding said zeolite several times, rubber milling and sulfurizing.

Description

technical field [0001] The invention relates to a preparation method of natural hephtilite as a rubber reinforcing additive. Background technique [0002] Stellerite is a mineral species in the pyroxene family, its chemical composition (weight percent): SiO 2 58.76、Al 2 o 3 14.13, CaO8.80, K 2 O0.11, Na 2 O0.18, Fe 2 o 3 0.44, H 2 o + 16.87, H 2 o - 1.25, its chemical formula is (K 0.017 Na 0.042 Ca 1.73 ) 1.189 [Al 1.997 Si 7. 5i 7.05018 ]6.75H 2 O. Natural stilbene is a hydrous alkali metal or alkaline earth metal aluminosilicate mineral, a framework silicate composed of silicon-oxygen tetrahedrons and aluminum-oxygen tetrahedrons. The oxygen atom in the aluminum oxygen tetrahedron has a valency and is not saturated, and the entire aluminum oxygen tetrahedron is negatively charged, and the nearby positively charged cations such as K + 、Na + , Ca 2+ , Mg 2+ Such as alkali metal or alkaline earth metal ions to compensate for the balance. With the func...
