Problems solved by technology

[0003] At present, the characteristics of the Zikou wear-resistant rubber formula are mainly manifested in two aspects: (1) In terms of raw rubber, a large amount of butadiene rubber is used to reduce heat generation and improve the wear resistance of vulcanized rubber; (2) In terms of fillers, Increase the modulus of the rubber compound by increasing the amount of carbon black, but this method is likely to cause difficulty in processing the rubber compound, and the dispersibility of carbon black is worse, resulting in a decrease in the physical and mechanical properties of the vulcanized rubber

Abstract

The invention relates to seam allowance abrasion resisting glue containing short fiber and a preparation method thereof. The seam allowance abrasion resisting glue containing the short fiber is characterized by comprising the first step of primary mother mixing, wherein natural rubber, butadiene rubber, carbon black N375 nylon short fiber, an anti-aging agent 4020, zinc oxide, stearic acid and aromatic hydrocarbon oil are sequentially added into an internal mixer to be subjected to banburying, and primary mother glue is obtained; the second step of secondary mother mixing, wherein the primary mother glue is added into the internal mixer to be subjected to banburying, and secondary mother glue is obtained; the third step of final mixing, wherein the secondary mother glue, insoluble sulfur and accelerant DZ are added into the internal mixer to be subjected to final mixing, and the seam allowance abrasion resisting glue is obtained. The seam allowance abrasion resisting glue containing the short fiber and the preparation method are suitable for full-steel radial tire seam allowance glue protection parts, a traditional mixing technology is adopted to a formula for mixing, the nylon short fiber is subjected to phenolic resin latex immersion treatment, and the adhesive strength of the nylon short fiber with rubber is improved.

Description

technical field [0001] The invention relates to a formulation of wear-resistant rubber for slits, in particular to wear-resistant slits containing short fibers and a preparation method thereof. Background technique [0002] The spigot position of the tire is in close contact with the rim, transmitting the driving force of the axle to the various components of the tire. This position has important requirements for the strength, wear resistance, heat generation, and creep resistance of the rubber compound. Load-bearing truck tires run under high-load conditions, and the friction between the spigot rubber and the rim is harsh, which leads to an increase in the temperature of the rubber compound (the temperature can reach 100 ° C), accompanied by the mechanical strength and wear resistance of the rubber compound. Decreased significantly. Ordinary rim wear-resistant rubber is prone to kerf cracking and tearing under high load conditions, which seriously affects the quality of t...
