Rubber composition, production method and shock-absorbing foot mat produced thereof

Abstract

The invention discloses a rubber compound, which is characterized in composed of following materials at the mass ratio of 40-60% diene rubber, 30-50% reinforcing filler, 3-5% activator, 0.8-1.2% vulcanizer, 0.7-2.0% vulcanization accelerator, and 1-3% plasticizer. The invention discloses a preparation method which comprises (1), arranging rubber into an open mill to be milled uniformly, (2) adding reinforcing filler, activator and soften plasticizer into the milled uniform rubber in turn, milling uniformly, discharging rubber, and cooling, (3), freshening the cooled rubber mixture, adding vulcanizer and vulcanization accelerator, vulcanizing, slicing, drying and obtaining the rubber compound. The invention discloses a relative damping foot mat. The inventive rubber compound has good property, simple production and good compatibility.

Description

Technical field [0001] The invention relates to a rubber material and products, in particular to a rubber composition, a preparation method and a shock-absorbing foot pad prepared therefrom. Background technique [0002] In the prior art, the material used to prepare the foot pad is generally plastic or rubber, but the plastic is relatively hard, has poor cushioning performance, and has poor resistance to abrasion. However, the performance of existing rubber materials cannot directly meet the manufacturing requirements. At the same time, it has good strength, insulation, abrasion resistance, and anti-aging performance for small electrical appliances and instruments and equipment. [0003] Generally, small electrical appliances and equipment are placed on the ground through several feet or fulcrums. Since vibration will affect their performance during the movement, in order to absorb shock, rubber or plastic shock absorbers are generally installed on the feet or fulcrums. Pads or ...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the material used to prepare foot pads is generally plastic or rubber, but the plastic is relatively hard, the anti-cushion performance is not good, and the plastic wear resistance is poor; and the existing rubber materials, its performance cannot be directly suitable for manufacturing requirements. Shock-absorbing foot pads for small electrical appliances and instruments with good strength, insulation, wear resistance, and anti-aging properties

[0003] Generally, small electrical appliances and instruments are placed on the ground through several feet or fulcrums. Since the vibration will affect their performance during the movement, in order to absorb shocks, rubber or plastic shock absorbers are generally installed on the feet or fulcrums. Pads or shock-absorbing sleeves, the parts of these shock-absorbing pads or sleeves in contact with the ground are all solid structures. The solid structure has high rigidity, small vibration frequency and amplitude, and cannot balance the vibration displacement of small electrical appliances and equipment during the moving process, resulting in its The relative sliding of the internal components, the number of times is too many, the performance will be reduced, and its service life will be affected

[0004] However, the friction coefficient between the existing foot pads or covers and the ground is relatively large, and the resistance of electrical appliances and equipment is relatively large during the translation process, and it is often difficult to move along the contact surface. The friction between the small foot pad or cover and the ground has also become a technical problem that needs to be solved

[0005] In the prior art, there is also a structural design with a partially hollow bottom, but its structure is relatively complicated, and the manufacturing steps are cumbersome. In addition, because the connection method between the foot pad and the machine body is single, it is usually connected by setting it on the machine. Therefore, its installation is also easily restricted by the shape and structure of the bottom of the machine, which is inconvenient to use
