Rubber material for manufacturing dumbbell and manufacturing process thereof

Abstract

The invention relates to the technical field of rubber material preparation, in particular to a rubber material for manufacturing a dumbbell, which is composed of natural rubber, butyl rubber, butadiene styrene rubber, nitrile rubber, an anti-aging agent, an accelerant, styrene-butadiene latex, a vulcanizing agent, a plasticizer and a cross-linking agent. The mass fraction of each component is as follows: 50-62% of the natural rubber, 10-13% of the butyl rubber, 5-8% of the styrene-butadiene rubber, 5-8% of the nitrile rubber, 1-2% of the anti-aging agent, 0.5-1% of the accelerant, 3-7% of the styrene-butadiene latex, 1-1.5% of the vulcanizing agent, 0.5-1% of the plasticizer and 1-2% of the cross-linking agent. In the rubber preparation process, the accelerant and the vulcanizing agent are used for vulcanizing the rubber at the same time, and the cross-linking agent is added in the vulcanizing process, so that the cross-linking density among rubber molecules can be greatly improved, gaps among the molecules of a rubber finished product are reduced, moisture can be prevented from permeating into the rubber to a great extent, and the service life of the rubber is prolonged. Further, the sweat resistance of the rubber is greatly improved, and the service life of the whole rubber is prolonged.

Description

technical field [0001] The invention relates to the technical field of rubber material preparation, in particular to a rubber material for making dumbbells and a manufacturing process thereof. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and is a widely used industrial material. Rubber products are widely used in industry or in all aspects of life, and dumbbells are used to strengthen muscles. Simple equipment for strength training. Its main material is cast iron, and some dumbbells are covered with a layer of rubber. When the user uses the dumbbell, due to the long-term grip of the hand, the surface of the rubber will be stained with a lot of dirt. Sweat stains, and in most cases, the user will not wipe the surface of the dumbbell after the exercise, which will cause the rubber on the surface of the dumbbell to be eroded by sweat stains, which will affect the service life of t...

AI Technical Summary

Problems solved by technology

By reducing the friction coefficient of composite materials, improving the wear resistance of materials and prolonging the service life of materials, it has great practical value, but it has not optimized the corrosion resistance of rubber and needs to be improved.

[0004] Chinese Patent No. CN104910475A discloses a reclaimed rubber material, which mainly improves the utilization of waste rubber powder, and the manufactured sole has the performance of rubber sole and can use thermoplasticity, which reduces the process and relatively reduces energy consumption, and makes full use of the regenerated rubber. Good elasticity, aging resistance, temperature and cold resistance, environmental protection and energy saving, high production efficiency, also did not change the corrosion resistance of the rubber itself, and needs to be improved
