High-temperature-resistant synthetic rubber for color sorter and preparation method of high-temperature-resistant synthetic rubber

Abstract

The invention discloses a high-temperature-resistant synthetic rubber for a color sorter. The high-temperature-resistant synthetic rubber is prepared from the following raw materials: 40-60 parts of styrene-butadiene rubber, 3-4 parts of an anti-aging agent 1010, 4-5 parts of polytetrafluoroethylene, 2-3 parts of magnesium oxide, 1-3 parts of magnesium silicate hydrate ultrafine powder, 2-3 parts of an anti-aging agent OD, 3-5 parts of mica powder, 3-4 parts of an accelerator M, 20-40 parts of polybutadiene rubber, 30-40 parts of N660 carbon black, 2-4 parts of aluminum hydroxide, 5-8 parts of nitrocellulose plastic, 4-5 parts of phthalate and 10-12 parts of modified diatomite. The synthetic rubber disclosed by the invention is used for replacing the ordinary spring used in the vibrator of the conventional color sorter so as to achieve a better damping effect; according to the synthetic rubber, by adding polytetrafluoroethylene, the characteristics of high temperature resistance and corrosion resistance are increased and meanwhile the preparation process is simple and the synthesized rubber has stable quality.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a high-temperature-resistant synthetic rubber for a color sorter and a preparation method thereof. Background technique [0002] Color sorter is a device that uses photoelectric technology to automatically sort out different-color particles in granular materials. It is widely used in grain, food, pigment chemical and other industries. It has the advantages of labor saving, time saving, high efficiency and low cost. . But the vibrator in the existing color sorter generally uses common spring damping, and the effect is general and easy to damage, so the inventor designs a kind of synthetic rubber to replace the spring in the vibrator, and utilizes the synthesis process of secondary vulcanization to make the rubber product further Cross-linking improves the mechanical properties and compression permanent deformation properties of synthetic rubber. It is suit...

But the vibrator in the existing color sorter generally uses common spring damping, and the effect is common and easily damaged, so the inventor designs a kind of synthetic rubber to replace the spring in the vibrator, and utilizes the synthesis process of secondary vulcanization to make the rubber product further Cross-linking improves the mechanical properties and compression permanent deformation properties of synthetic rubber. It is suitable as a shock absorber for color sorters and used for a long time. It greatly improves the working performance of color sorters and creates better economic benefits.
