Water-resistant and anti-aging synthetic rubber for color sorters and preparation method thereof

Abstract

The invention discloses a water-resistant and anti-aging synthetic rubber for color sorters, which is prepared from the following raw materials in parts by weight: 40-50 parts of ethylene propylene terpolymer, 30-40 parts of a butadiene rubber, 2-5 parts of talcum powder, 1-3 parts of aluminum hydroxide, 20-30 parts of super light silica, 2-4 parts of diethylene glycol, 1-2 parts of an accelerator TETD, 2-3 parts of an antiager A, 20-40 parts of N220 carbon black, 3-4 parts of styrene, 1-3 parts of m-xylylenediamine, 2-4 parts of 3-aminopropyltrimethoxysilane, 1-3 parts of paraffin wax, and 10-12 parts of modified diatomite. The synthetic rubber disclosed by the invention replaces a common spring used in a vibrator of an existing color sorter so as to achieve a better shock-absorbing effect; and the 3-aminopropyltrimethoxysilane added in the synthetic rubber disclosed by the invention can enhance the cohesiveness of the synthetic rubber, increase the mechanical, electrical, water resistant and anti-aging properties and the like of products, and improve the wettability and dispersity of filler in polymers.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a water-resistant and anti-aging 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 ...

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.
