Novel wear-resistant plastic barbell

Abstract

The invention relates to a novel wear-resistant plastic barbell. The novel wear-resistant plastic barbell is prepared from the following components in parts by weight: 15 to 18 parts of polyvinyl chloride resin, 3 to 7 parts of zinc oxide, 7 to 9 parts of calcium carbonate powder, 4 to 10 parts of rubber latex powder, 6 to 12 parts of quartz powder, 3 to 7 parts of 2,2,4-trimethyl-1,3-pentanediolmono(2-methylpropanoate), 3 to 8 parts of stabilizer, 12 to 23 parts of low-pressure polyethylene, 7 to 12 parts of POE, 10 to 14 parts of tetrapentaerythritol ester, 4 to 6 parts of paraffin, 25 to 35 parts of filling agent, 2 to 4 parts of tribasic lead sulfate, 7 to 8 parts of calcium carbonate, 6 to 9.4 parts of epoxy butyl stearate, 1 to 3 parts of calcium stearate, 4 to 8 parts of dibasic lead sulfate, 4 to 6 parts of dioctyl phthalate, 6 to 13 parts of lead stearate, 20 to 45 parts of polyethylene resin, 5 to 8 parts of carbon black, 3 to 4 parts of paraffin, 5 to 9 parts of sodium antimonite, 8 to 11 parts of nano silicon dioxide, 2.5 to 7 parts of tribasic lead sulfate, 3 to 6 parts of dimethyl siloxane and 30 to 45 parts of PE. The novel wear-resistant plastic barbell is relatively good in hand feeling, high in rate of finished products, and excellent in performance.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a novel wear-resistant plastic barbell. Background technique [0002] The barbell has a wide range of uses, whether it is the muscles of the shoulders, back, arms, chest, etc., use multiple times of special muscle strength training techniques to do muscle endurance training for the whole body muscles, burn fat, convert it into a fit line, and improve Muscles that have been exercising for a long time but are still loose locally; in addition, it can delay muscle aging, increase bone density, and prevent osteoporosis. There are two kinds of materials for barbells on the market: metal products and plastic products. Metal barbells are generally more expensive. Expensive, increases people's economic burden, and plastic barbell is cheap, but existing barbell is generally not enough in wear resistance, and after long-time use, cracking phenomenon can occur, slightly careless, may cause p...

[0002] The barbell has a wide range of uses, whether it is the muscles of the shoulders, back, arms, chest, etc., use multiple times of special muscle strength training techniques to do muscle endurance training for the whole body muscles, burn fat, convert it into a fit line, and improve Muscles that have been exercising for a long time but are still loose locally; in addition, it can delay muscle aging, increase bone density, and prevent osteoporosis. There are two kinds of materials for barbells on the market: metal products and plastic products. Metal barbells are generally more expensive. Expensive, which increases people's economic burden. Plastic barbells are cheap, but the existing barbells generally have insufficient wear resistance. After a long time of use, cracking will occur, and a little carelessness may cause personal injury
