Abstract
The invention discloses a rubber compound special for a caster. The rubber compound comprises, by mass, 65-80 parts of acrylic rubber, 15-20 parts of fluorinated silicone rubber, 5-15 parts of polyester type TPU, 40-60 parts of fast extrusion furnace black, 0.5-1.5 parts of a 3# vulcanizing agent, 1-1.5 parts of stearic acid, 4-8 parts of a crosslinking agent, 5-10 parts of a softeningplasticizer, 1-2 parts of a dispersing agent, 8-10 parts of metallic oxide, 2-4 parts of processing oil, 2-3 parts of an anti-ageing agent and 2-3 parts of a scorch retarder. A proper type of rubber is selectedto be matched with an elastomer to serve as the base material of rubber, and the rubber product has excellent oil resistance, high temperature resistance, chemical corrosion resistance and excellent comprehensive physical performance. The caster prepared from the rubber product has excellent anti-ageing performance and is quite and free of noise during operation, free of traces during rolling, andsuitable for the environment high in cleaning requirement.
Description
technical field [0001] The invention belongs to the field of rubber, and in particular relates to a special compounded rubber for casters and a preparation method thereof. Background technique [0002] Casters, including movable casters and fixed casters. Swivel casters are often called universal wheels, and its structure allows 360-degree rotation; fixed casters have no rotating structure and cannot be rotated. Casters are widely used in mining, mechanical equipment, electronic equipment, medical equipment, engineering decoration, textile, printing and dyeing, furniture, logistics equipment, warehousing, turnover vehicles, chassis, cabinets, equipment, electromechanical, dust-free workshops, production lines, large supermarkets, etc. Many industries and various fields. [0003] There are many kinds of casters, such as rubber casters, polyurethane casters, plastic casters, nylon casters, steel casters and so on. Each material has advantages and disadvantages. For example...
