Abstract

The invention provides reclaimed rubber and a tire made thereof. The reclaimed rubber comprises the following materials: waste tire rubber powder, glass fibers, nylon fibers, acrylic polyurethane, polyamide, styrenated phenol, 3-diphenylguanidine, polystyrene resin, an epoxy resin composition, abietic acid, rosin anhydride, carbon black, aromatic disulfide and zinc salt. The tire made of the reclaimed rubber comprises a tire body; the tire body comprises two tire side surfaces and a tire peripheral surface positioned between the two tire side surfaces; air guide blocks are distributed on at least one tire side surface, and an air guide groove is formed between the two adjacent air guide blocks; multi-ring brake pattern blocks are arranged on the tire peripheral surface and are symmetrically arranged about a center line of the tire peripheral surface, a flow guide groove is formed between the two adjacent brake pattern blocks on the same ring, and the air guide groove is connected with the flow guide groove. The reclaimed rubber provided by the invention is high in mechanical strength, strong in elasticity, aging-resistant, cold-resistant, high temperature-resistant and strong in braking performance and driving performance, and meanwhile, the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a regenerated rubber and a tire made from the rubber. Background technique [0002] With the rapid development of automobile industrialization, there are more and more scrapped rubbers. According to statistics, more than 10 million tons of tires are scrapped every year in the world. How to effectively use these discarded rubbers has become a major concern of the rubber industry in various countries. [0003] As a renewable resource, waste tire rubber powder is widely used and is becoming more and more common. It is used to produce recycled rubber, and then to produce various rubber products, such as recycled tires, for construction materials, such as for paving highways , playgrounds, floors, carpets, etc., suitable for nursing homes, kindergartens, wards, courts, playgrounds, gyms and various playgrounds. It is characterized by good elasticity, good aging resistance, non-slip, i...
