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...

Embodiment 1

[0026] see figure 1 , the present invention provides a technical solution: a rubber material for making dumbbells is made of natural rubber, butyl rubber, styrene-butadiene rubber, nitrile rubber, anti-aging agent, accelerator, styrene-butadiene latex, vulcanizing agent, plasticizer and cross-linking agent. Joint agent composition, and the mass fraction of each component is as follows: natural rubber 58%, butyl rubber 13%, styrene-butadiene rubber 8%, nitrile rubber 8%, antioxidant 2%, accelerator 0.5%, styrene-butadiene latex 7% %, vulcanizing agent 1%, plasticizer 0.5% and crosslinking agent 2%.

[0027] The material of the anti-aging agent is one or two of anti-aging agent D, anti-aging agent RD and anti-aging agent MB. Using anti-aging agent D, anti-aging agent RD and anti-aging agent MB as anti-aging agent is not only non-toxic and harmless, but also can greatly improve The service life of rubber products, the material of the accelerator is one or more of zinc diethyl di...
