Embodiment 1

[0018] The high-performance engineered tire tread rubber formula based on nano powder of the present embodiment is:

[0019]

[0020]

[0021] The preparation process of the high-performance engineering tire tread rubber based on nano-powder of the present embodiment is:

[0022] a. Ingredients: Weigh the required quality of various raw materials according to the formula weight ratio.

[0023] b. Mixing: keep the temperature of the front roll of the open mill at 55°C and the temperature of the rear roll at 50°C. Firstly, the plasticized natural rubber is wrapped on the front roll after passing through the roll gap of the open mill, and an appropriate amount of rubber is left above the roll gap. After 2 minutes of kneading to form a smooth and gap-free wrapping rubber, the rubber material is cut and removed; then the rubber material is put into the roller distance and pressed for 2 minutes, and zinc oxide, stearic acid, and anti-aging agent are sequentially added to the a...

Abstract

The invention relates to a high performance nano powder body-based tread rubber of engineering tires and a preparation process thereof. The tread rubber comprises the following components: 100 weight portions of natural rubber, 40 to 55 weight portions of carbon black, 3 to 10 weight portions of zinc oxide, 1 to 3 weight portions of stearic acid, 1.1 to 2 weight portions of anti-ageing agent 4020, 1.1 to 2 weight portions of anti-ageing agent RD, 1 to 2 weight portions of promoter NOBS, 1.5 to 2.5 weight portions of sulfur, and 1 to 15 weight portions of modified nano powder body. The preparation process for the tread rubber comprises the following steps: a, mixing; b, milling; c, sulfuration with the sulfuration pressure of 15 to 20 MPa, a sulfuration temperature of 143 to 150 DEG C and the sulfuration time of 10 to 30 minutes; d, demoulding; e, posttreatment, and the like. A modified nano powder body and the rubber are compounded through a mechanical co-mixing method; and the high performance rubber nano composite tread rubber is obtained after sulfuration. The tread rubber has high strength, tear resistance, high wear and pricking resistance, and chunking and chipping resistance, and is suitable for the ties of large engineering machineries under complex and extreme construction conditions such as loaders, cranes, bulldozers, and the like.

Description

technical field [0001] The invention relates to a high-performance engineering tire rubber based on nanopowder and a preparation process thereof, and belongs to the technical field of advanced nanocomposite materials and preparation. Background technique [0002] With the rapid development of the national economy, the country's investment in infrastructure construction has increased year by year, and the construction machinery and equipment used in mining, water conservancy, road construction and other industries are increasing day by day. The general working environment of construction machinery is harsh and the work intensity is high, so higher requirements are put forward for engineering tires. Compared with bias-ply OTR tires, radial OTR tires have stronger load capacity, and have the advantages of wear resistance, puncture resistance, and high reliability, and are the main direction of OTR tire development. [0003] The key to realizing high-quality radial tires lies i...
