Abstract

The invention discloses ageing-resisting magnetic rubber powder. The ageing-resisting magnetic rubber powder is prepared from the following raw materials in parts by weight: 1 to 2 parts of anti-ageing agent rd, 100 to 110 parts of natural rubber powder, 0.4 to 1 part of potassium oleate, 30 to 40 parts of ferrous chloride tetrahydrate, 17 to 20 parts of ferric chloride hexahydrate, 2 to 3 parts of trimethylolpropane, 3 to 4 parts of 6-hydroxy-2-naphthoate, 0.1 to 0.2 part of dibenzothiazyl disulfide, 0.01 to 0.02 part of catalyst and 25 to 30 parts of 10 to 12 percent ammonia water. The ageing-resisting magnetic rubber powder disclosed by the invention takes p-tolenesulfonate as the catalyst and effective blending of the magnetic raw materials and the rubber powder is realized; the mechanical stability of a finished-product material is improved.

Description

technical field [0001] The invention belongs to the field of rubber materials, and in particular relates to an aging-resistant magnetic rubber powder and a preparation method thereof. Background technique [0002] Natural rubber (NR) is a natural polymer compound with cis-1,4-polyisoprene as the main component, and 91% to 94% of its components are rubber hydrocarbons (cis-1,4-polyisoprene dienes), and the rest are non-rubber substances such as proteins, fatty acids, ash, sugars, etc. Natural rubber is the most widely used general-purpose rubber, the physical characteristics of natural rubber. Natural rubber has high elasticity at room temperature, slightly plastic, has very good mechanical strength, low hysteresis loss, and low heat generation during multiple deformations, so its flex resistance is also very good, and because it is non-polar Rubber, so the electrical insulation performance is good. [0003] Chemical properties of natural rubber. Because of unsaturated do...
