Soft metal, and preparing method and use thereof

Abstract

The invention refers to a kind of soft metal, whose characters lie in it is made up of natural rubber, stearic acid, zinc oxide, sulfur, metal powder, accelerator and age-inhibiting additive. The invention not only has elastane, scratchability of rubber product, and easy to be shaped, but also has specific density of normal metal. In the same condition, the mass of the product is bigger than normal rubber product by several times. The density of the product is even, and the use field is spread. The invention also refers to a manufacturing method of the soft metal, by using the method; more metal powder can be combined with natural rubber, and gets the high limit specific density region. The invention also refers to some sport device made by the soft metal product.

Description

technical field [0001] The invention relates to a modification of rubber, in particular to a soft metal made from a rubber-containing composition. The invention also relates to a preparation method of the soft metal and its use in preparing sports equipment. Background technique [0002] Rubber products generally have the characteristics of large volume and light weight, while metals have the characteristics of large specificity, small elasticity, and poor softness. In the prior art, there is no modified material of rubber with good elasticity and large specific gravity. When a material with good elasticity and high specific gravity is required, rubber is generally coated on the outer surface of the large metal block to make the two stick together. The disadvantage is that the rubber is easy to fall off from the large metal block, and the composite process is relatively relatively Complex, and due to the large difference in proportion between the t...

AI Technical Summary

Problems solved by technology

When a material with good elasticity and high specific gravity is required, rubber is generally coated on the outer surface of the large metal block to make the two stick together. The disadvantage is that the rubber is easy to fall off from the large metal block, and the composite process is relatively relatively Complex, and due to the large difference in the specific gravity of the two, the overall specific gravity is uneven, and its application field is too narrow

However, it cannot be applied to some occasions where the elasticity ratio is large and uniform.
