Abstract
The invention discloses a rubber roller for a rice huller. The rubber roller comprises the following substances in parts by weight: 80 parts of nitrile rubber, 10-12 parts of dioctyl phthalate, 12 parts of phenolic resin, 0.8-1.2 parts of octylated diphenylamine, 1 part of sulfenyl silane, 2-3 parts of trimethylenediamine, 1-2 parts of an accelerant, 2-3 parts of sulfur, 50-55 parts of carbon black, 4-5 parts of zinc oxide and 1-2 parts of stearic acid. According to the rubber roller, carbon black and a coupling agent are combined for use, so that the rubber roller has required high strength and wear resistance, and the hardness, strength and wear resistance of a rubber material are improved.
Description
Technical field
The present invention relates to a kind of rubber, particularly relate to a kind of rubber roller for rice huller.
Background technology
Grain husking process is generally through three basic steps: extruding, rub with the hands and tear, peel off, and wherein rubs that to tear is the key of shelling with the hands, rubs the size of tearing with the hands and depends on two important factors: one is the size of frictional force, and the size of frictional force depends on the pressure size between two rollers; Two is the length of this reverse friction power in the relativity time of grain, and the length of this action time depends on two roller speed of relative movement, and namely linear speed difference is relevant.Be not difficult to find out: roll gap pressure and linear speed difference are the important processing parameters of rice hulling, not only directly affect husking yield, affect the consumption of rubber roll too to its selection correctness.
Rubber roll is the key fitment on hulling machine, is the key equipment of rice hulling.Its principle of work is that two rubber rolls make paddy enter the effect played between two rollers and extrude and tear and rub with the hands and peel off by reverse variable speed rotation, thus reaches the object that shelling is rice.The outer field color of rubber roll has: have brown, black, white, redness, yellow, purple, grey, beige, blue, green etc., can determine color according to demand.Paddy hulling rubber roll outer layer glue hardness (Tai Shi A type) has 90o-95o etc., can according to weather, paddy kind and other demand determination hardness.Paddy hulling rubber roll kind has three major types, current China and claim three large series in the world, is named as respectively: wheeled, shell type, take formula, and wheeled and shell type uses more at present.
Summary of the invention
The invention provides and a kind of there is required high strength and high-wearing feature, the rubber roller for rice huller that the hardness of its sizing material, intensity and wear resisting property increase.
A kind of rubber roller for rice huller, by mass parts, comprises following material:
Paracril 80 parts, o-phthalic acid dibutyl ester 10 ~ 12 parts, 12 parts, resol, octylated diphenylamine 0.8 ~ 1.2 part, 1 part, sulfenyl silane, cyclonite diamines 2 ~ 3 parts, promotor 1 ~ 2 part, 2 ~ 3 parts, sulphur, carbon black 50 ~ 55 parts, 4 ~ 5 parts, zinc oxide, stearic acid 1 ~ 2 part.
Preferably, a kind of rubber roller for rice huller, by mass parts, comprises following material:
Paracril 80 parts, o-phthalic acid dibutyl ester 11 parts, 12 parts, resol, octylated diphenylamine 1.0 parts, 1 part, sulfenyl silane, cyclonite diamines 2.6 parts, promotor 1.4 parts, 2.5 parts, sulphur, carbon black 53 parts, 4.5 parts, zinc oxide, stearic acid 1.5 parts.
Described promotor is accelerator CBS, or one or several in accelerant NOBS.
Described carbon black is precipitated silica, or one or several in white carbon black.
The massfraction of described cyclonite diamines is 68%.
A kind of rubber roller for rice huller is obtained by following steps:
Fritter paracril is put into colloidal sol still, under rotating speed 45r/min, add o-phthalic acid dibutyl ester, resol, octylated diphenylamine, sulfenyl silane, cyclonite diamines, promotor, sulphur, carbon black, zinc oxide and stearic acid, make it to dissolve, then be uniformly mixed, obtain the rubber roll of invention.
Rubber roll of the present invention makes carbon black be combined with coupling agent, makes rubber roll have required high strength and high-wearing feature, and the hardness of its sizing material, intensity and wear resisting property increase.
