Description
Technical field
The present invention relates to the granulating technique in rubber industry field, be specifically related to a kind ofly prepare anti-thinization and to revert the prilling process of agent.
Background technology
Two (the lemon acid imide methyl) benzene (Bcl-lx) of 1,3-is that a kind of novel anti-thinization is reverted agent, can effectively prevent sizing material from reverting.No matter revert by under high temperature vulcanized, over cure, high temperature use cause, Bcl-lx can afford redress to properties of rubber, thus improves the performance of sizing material.Bcl-lx is show activity when recovery appears in sizing material, does not affect incipient scorch, sulphidity and vulcanized mechanical, does not need adjustment formula or technique.And in curing bag glue, add the service life that Bcl-lx obviously can extend curing bag.Bcl-lx is a kind of pulverulent solids, exist soot density little, easily fly upward, easily cause the problems such as irritated.Along with improving constantly of environmental requirement, therefore, need to carry out granulation to this kind of powdery product.
Rotary-belt condensation granulator commercially available at present; its performance characteristics comprises: the grain shape of the product prepared and epigranular; be conducive to transport, packaging and use, be conducive to the improvement of production and use procedure operating condition and environment, product quality and competitiveness are significantly improved.Adopt thin steel band to conduct heat and atomizing spray pressure cooling, make hot melt material obtain rapid condensation, solidification, production efficiency significantly improves.Distributing device and steel band all adopt frequency converter timing drive unit, can control according to production capacity and material characteristic step-less adjustment.Adopt intelligent PID temperature controller substep to control each point temperature, ensure that the stable of temperature of charge and material state, granulation quality obtains reliable guarantee.Because the commutation of steel band at delivery end bends, make the faying face of cured granulate and steel band be easy to peel off, therefore during discharging, dust is few, and grain shape is protected, and brings the impurity content of product when also reducing scraper into simultaneously.Adopt sub-sectional cooling, according to material condensation, curing characteristics, the chilling temperature of each section can be selected, cooling is fast realized to special material, solidification is very favourable.Rotary-belt condensation granulator have employed the scheme of building block system combination in its structural design, is conducive on the one hand selecting specification of equipment according to material characteristic and production capacity, is more conducive to transport and the installation of large gauge device simultaneously.
Summary of the invention
The object of the invention is to the above-mentioned defect overcoming prior art existence; a kind of prilling process of anti-recovery agent is provided; adopt rotary-belt condensation granulator equipment to carry out granulation processing to this anti-recovery agent, make it easy to transport, metering and meet the environmental requirement of modern industry.
The prilling process of a kind of anti-recovery agent that the present invention proposes, adopts rotary-belt condensation granulator to carry out granulation to anti-recovery agent, comprises the following steps:
(1) add in anti-recovery agent by binding agent, fusing, stirs, obtains fused materials.
(2) fused materials is added in rotary-belt condensation granulator; fused materials continus convergence enters in the distributing device of constant temperature; after distributing device is uniform by fused materials by pressure; material is converted into the drop of interrupted drippage downwards along width of steel band scope; on the steel band of at the uniform velocity movement below being dropped in; the cooling of the continuous atomizing sprayer under being arranged on steel band; described fused materials is moving and is being cooled fast in course of conveying and solidify, thus anti-recovery agent described in the hemispherical grain product of formation regular shape.
In prilling process of the present invention, the revert particle diameter of agent of described anti-thinization is 3 ~ 5mm.The agent of reverting of described anti-thinization is 1,3-couple of (lemon acid imide methyl) benzene, that is, Bcl-lx.
In prilling process of the present invention, described binding agent is stearic acid, paraffin or soap.
In prilling process of the present invention, the consumption of described binding agent is 0% ~ 50% of material gross mass.Preferably, described consumption of binder is 10% ~ 30% of material gross mass.
In prilling process of the present invention, in described step (1), it is 60 ~ 120 DEG C by heating material to the heating-up temperature of molten condition.
In prilling process of the present invention, in described step (1), the time stirred by fused materials is 10 minutes to 1 hour.Preferably, the time stirred by fused materials is 20 to 40 minutes.
Prilling process of the present invention utilizes rotary-belt condensation granulator that dry powder anti-recovery agent Bcl-lx is processed into granular product; the granular product prepared is the hemispherical grain product of regular shape; uniform particles rule, hardness is moderate, and surface is mellow and full smooth; easy to use; pelletized product more easily measures, easier shipping storage, no dust pollution; reduce human injury, meet environmental requirement etc.
