Abstract
The invention provides a modified natural rubber solid tyre. The modified natural rubber solid tyre is prepared from the following raw materials in parts by weight: 90 to 110 parts of natural rubber, 1 to 3 parts of sulfur, 3 to 4 parts of an accelerant, 4 to 6 parts of zinc oxide, 1 to 2.5 parts of stearic acid, 1 to 3 parts of paraffin, 0.5 to 1.5 parts of ferric oxide, 4 to 6 parts of adhesive, 1 to 3 parts of rubber scarlet LC, 110 to 150 parts of fillers, 8 to 12 parts of engine oil, 8 to 10 parts of oligomer ester 12-II and 0.69 to 1.275 parts of a muting agent. The muting agent is added into the formula system, so the prepared modified natural rubber solid tyre has higher sound-absorbing coefficient, high sound-absorbing property, low cost, high hardness, high breaking strength, higher anti-ageing property, higher elasticity and long service cycle, reduces cost and increases enterprise benefit.
Description
technical field [0001] The invention relates to the technical field of solid tires, in particular to an anti-aging and sound-absorbing modified natural rubber solid tire. Background technique [0002] With the continuous development of industrial vehicles, the performance requirements of tires are getting higher and higher. The rapid development of my country's automobile industry, mining industry and other industries and the needs of fire protection and isolation of flammable products have put forward higher requirements for the performance of rubber products. The demand for it shows a trend of rapid growth. Solid tires are generally used under high loads, and the rubber compound is required to have sufficient pressure resistance and wear resistance, high enough modulus stress, high hardness, Low permanent deformation and good wear resistance. At present, due to the unsaturated double bonds contained in natural rubber molecules, the traditional natural rubber solid tires hav...
