Embodiment 1

[0024] Weigh 5g of cerium oxide, add 1200ml of deionized water, and stir in a water bath at 70°C for 20min with a speed rating of 20. Weigh 0.1g of sodium lauryl sulfate, add a small amount of ethanol, and add deionized water to make a 600ml solution, add the solution dropwise to cerium oxide with a peristaltic pump, let it settle after 3 hours of reaction, take the upper layer solution, and suction filter drying to obtain sodium dodecyl sulfate modified cerium oxide. Stearic acid-modified cerium oxide was prepared by the same method, wherein the amount of stearic acid was 0.2 g, the reaction time was 1 h, and the rotational speed grade was 15.

[0025] Cerium oxide modified with sodium lauryl sulfate and stearic acid is added to the track shoe rubber in the plasticizing stage at a ratio of 1:1.

[0026] The surface of cerium oxide was organically modified with two modifiers. On the basis of keeping the original production formula and technological process of the rubber trac...

Stearic acid-modified cerium oxide was prepared by the same method, wherein the amount of stearic acid was 0.2 g, the reaction time was 1 h, and the rotational speed grade was 15.

[0029] Cerium oxide modified with sodium lauryl sulfate and stearic acid is added to the glued track shoe rubber together with other small rubber materials in an internal mixer at a ratio of 1:1.

Embodiment 3

[0032] Weigh 5g of cerium oxide, add 1200ml of deionized water, and stir in a water bath at 70°C for 20min with a speed rating of 20. Weigh 0.1g of sodium lauryl sulfate, add a small amount of ethanol, and add deionized water to make a 600ml solution, add the solution dropwise to cerium oxide with a peristaltic pump, let it settle after 3 hours of reaction, take the upper layer solution, and suction filter drying to obtain sodium dodecyl sulfate modified cerium oxide. Stearic acid-modified cerium oxide was prepared by the same method, wherein the amount of stearic acid was 0.2 g, the reaction time was 1 h, and the rotational speed grade was 15.

[0033] Cerium oxide modified with sodium lauryl sulfate and stearic acid is added to the rubber of track shoes on the open mill together with sulfur at a ratio of 1:1.

[0034] The process of this example is different from that of Example 2 in that the compounded modified cerium oxide is added together with sulfur on the mill, and th...

Abstract

The invention discloses a method for improving the properties of rubbering track shoe rubber via compounding and modified cerium oxide. At least two modifying agents are respectively used for modifying the cerium oxide, on the basis of keeping the original production formula and production process constant, 0.1 to 10% of compounding and modified cerium oxide is added via a mechanical mixing method, and the properties, especially a wear-resisting property and a tearing resistance property, of the rubbering track shoe rubber are improved. The tensile strength and the tearing strength of the rubber obtained via the method are respectively increased by 11% and 41%, and wear loss is reduced by 16%. Therefore, the method is suitable for rubber tracks of large-scale machinery, such as tanks, derrick cranes, agricultural harvesters and the like.

Description

[0001] technical field [0002] The invention relates to a method for compounding and modifying cerium oxide to improve rubber properties of rubberized track shoes, and belongs to the technical field of advanced composite materials and preparation and modified rubber. Background technique [0003] As a strategic material, rubber occupies an important position in the national economy. Its unique viscoelasticity and compatibility are unmatched by other materials. Its use value is becoming more and more extensive with the development of economy and society. [0004] With the significant development of high-tech in the world, rubber has effectively promoted the development of the rubber industry. The progress of its new raw materials, new products, new equipment and new processes all benefit from the application of high-tech, and use high-tech to transform the traditional rubber industry. has become inevitable. [0005] Rare earth / polymer materials can be divided into two types...
