Anti-scorch synthetic rubber for color sorter and preparation method thereof

Abstract

The invention discloses scorch-resistant synthetic rubber for a color selector. The rubber is prepared from the following raw materials in parts by weight: 6-8 parts of SEBS rubber, 2-3 parts of phenolic resin, 1-2 parts of an antiager AW, 2-3 parts of N-cyclohexyl thiophthalimide, 25-35 parts of gaseous phase white carbon black, 55-75 parts of fluororubber, 1-2 parts of an accelerant DM, 2-4 parts of sulfur, 2-3 parts of nano argil, 3-4 parts of barite, 2-3 parts of diethylene glycol benzoate, 2-4 parts of vinyl silicone oil, 1-3 parts of hydroquinone and 10-12 parts of modified diatomite. The synthetic rubber disclosed by the invention is used for replacing a common spring which is used in an existing color selector vibrator so as to achieve a better damping effect. N-cyclohexyl thiophthalimide is added into the synthetic rubber disclosed by the invention, so that the rubber has a good scorch-resistant effect, and the storage stability of the rubber is greatly improved.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to an anti-scorch 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 suitable as a shock ab...

Problems solved by technology

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.
