Rubber and plastic foaming material for processing lower disc of strike type body building exercising device

Abstract

The invention discloses a rubber and plastic foaming material for processing a lower disc of a strike type body building exercising device, and relates to the technical field of rubber and plastic materials. The rubber and plastic foaming material is prepared from the following raw materials in parts by weight: 90 to 100 parts of butyl rubber, 30 to 40 parts of polyurethane rubber, 20 to 25 parts of polyvinyl chloride, 13 to 18 parts of modified diatomit, 12 to 16 parts of coal ash, 12 to 16 parts of rosin, 10 to 15 parts of coconut oil, 10 to 15 parts of palm wax, 10 to 15 parts of polyethylene glycol, 8 to 12 parts of sepiolite powder, 8 to 12 parts of activated calcium carbonate, 6 to 10 parts of sodium lignosulphonate, 5 to 8 parts of nanometer aluminium oxide, 4 to 7 parts of silane coupling agents, 3 to 5 parts of azodicarbonamide, 2 to 3 parts of propylgallate and 2 to 3 parts of diphenyl isooctyl phosphite. The prepared rubber and plastic foaming material has the advantages that the weight is light; excellent anti-striking performance, wear-resistant performance and anti-aging performance are realized; the striking force being 70kg can be born; the service life is long; after being used, the material can be recycled and reused, so that the environment is protected, and the production cost is reduced.

Description

Technical field: [0001] The invention relates to the technical field of rubber and plastic materials, in particular to a rubber and plastic foam material for processing the lower plate of hitting fitness training equipment. Background technique: [0002] With the development of science and technology and social progress, people's living standards continue to improve, social entertainment is more and more, people have little time to participate in fitness exercises, resulting in overnutrition, three high groups, especially the elderly, have cerebral infarction or cerebral thrombosis more and more people. In order to improve physical fitness, many fitness trainers suitable for families and indoors have emerged. [0003] Many fitness trainers are divided into an upper plate and a lower plate, and the lower plate can rotate 360 ​​degrees, and the purpose is to provide low leg attack and leg amputation training. Compared with the upper plate, the lower plate bears a greater imp...

Problems solved by technology

The traditional bottom plate processing materials are prone to wrinkle, damage and cracking, especially when used outdoors, the aging resistance is poor, and the replacement cycle is short, which increases the input cost
