Abstract

The invention relates to a waste rubber particle ultrafine grinding production method, in particular to a normal-temperature harmless treatment process of activator-added waste rubber particles, and can obtain 200-mesh ultrafine grinding activating rubber powder. The production method comprises before-grinding preprocessing, and is characterized in that 20-mesh waste rubber particles obtained in the before-grinding preprocessing are uniformly mixed with accessory ingredient, wherein the accessory ingredient is a mixture of activator480, desulfurizer diphenyl disulfide and softener C8H6O. Then, the 20-mesh waste rubber particles mixed with the accessory ingredient are fed into fluted disc grinder for grinding. In the grinding process, a main fluted disc of the fluted disc grinder is fixed, and an auxiliary fluted disc rotates around the main fluted disc. And in the grinding process, through the fact that a distance adjusting mechanism adjusts the distance between the auxiliary fluted disc and the main fluted disc, cutting and grinding are conducted to the rubber powder particles until the particle sizes of powder materials reach to about 200 mesh, and packaging is conducted after sieving.

Description

A kind of waste and old rubber particle ultra-fine grinding production method

Technical field

The present invention relates to a kind of breaking method of waste and old rubber particle, particularly a kind of normal temperature harmless treatment process that adds the waste and old rubber particle of activator can obtain 200 order ultra-fine grinding activated rubber powders.

Background technology

Along with the economic develop rapidly in the whole world, increasing polymer rubber rubbish causes serious environmental pollution at present.Can with waste old all, high value is recycled becomes a whether problem of sustainable development.Present industrialized utilization waste old is produced rubber powder and is mainly contained two kinds: normal temperature method and freezing.Two kinds of process routes all need through pulverizing the processes such as front preprocessing, pulverizing, separation and conveying, screening and packing.Because 200 order rubber powders have following characteristics: be narrower than 200 orders and after 220 degree desulfurization plastics processings, can mix in a large number its rubber, reduce producing cost; Restore, can keep about 2/3 of vulcanized rubber hot strength in the former damaged tire, and can keep the former physical property that rubber powder is taken the multiple auxiliary agent in the former tire material, environmental protection is good, do not contain coal tar, pine tar, appropriate and wet goods has smelly poisonous material in the used compounding ingredient of 200 order rubber powders, meet the requirement of environmental protection cleaning product, with regenerated rubber production relatively, 200 order rubber powders have reduced dynamic desulfurization, have opened the operations such as refining, refining in production technology, can the decrease energy resource consumption.But at present when reclaiming waste old, because present production technology can't make waste and old rubber particle can't reach 200 purpose ultra-fine grinding activated rubber powders, therefore the waste and old rubber particle that adopts now is generally about 40 orders, in recycling, can't reach 200 purpose technique effects, therefore demand developing novel waste and old rubber particle ultra-fine grinding production method urgently.

Summary of the invention

Under the condition of normal temperature, can't carry out the problem that ultra-fine 200 orders pulverizing obtains 200 purpose ultra-fine grinding activated rubber powders thereby the objective of the invention is to solve in the prior art to waste old, a kind of waste and old rubber particle ultra-fine grinding production method is provided.The present invention designs a kind of waste and old rubber particle ultra-fine grinding production method, comprise and pulverize front preprocessing, it is characterized in that: the 20 purpose waste and old rubber particles that preprocessing obtains before will pulverizing are mixed aid equably, auxiliary agent is activator 480, the mixture of desulfurizing agent and softening agent, then 20 purpose waste and old rubber particles with above-mentioned mixed aid join the pulveriser with fluted disk pulverizing, described pulveriser with fluted disk main tooth disk when pulverizing maintains static, auxiliary fluted disc rotates around main tooth disk, and in crushing process, regulate the distance of assisting between fluted disc and the main tooth disk by distance adjustor, rubber powder granule is cut and grinds, until powder particle size reaches about 200 orders packing after the screening.It is characterized in that: the mixed weight ratio of rubber powder, activator, desulfurizing agent, softening agent is 100 rubber powders: 0.5 activator: 1 desulfurizing agent: 10 softening agents.Advantage of the present invention is that a whole set for the treatment of process has that energy consumption is low, safety, environmental protection, non-pollutant discharge etc.

Below in conjunction with embodiment the present invention is elaborated.

The specific embodiment

At first the waste old that reclaims is washed, be mingled in wherein rubbish to remove some, then send crusher in crushing with junked tire, generally waste old need to be broken into the footpath grain is 20---the particle of 30 mm in sizes, with the waste and old rubber particle after the fragmentation, carry out after the pulverization process particle diameter reaches 20 orders, be mixed into pulveriser with fluted disk with activator 480, desulfurizing agent and softening agent by a certain percentage, concrete is the rubber powder of double centner, 0.5 the activator of kilogram, 1 kilogram desulfurizing agent, 10 kilograms softening agent.Pulveriser with fluted disk main tooth disk when pulverizing maintains static, auxiliary fluted disc rotates around main tooth disk, and in crushing process, regulate the distance of assisting between fluted disc and the main tooth disk by distance adjustor, rubber powder granule is cut and grinds, until powder particle size reaches about 200 orders, packing after the screening, store for future use, when the recycling of the production that is used for automobile tire, can add the 200 order superfine powders that the present invention of 30% obtains, first 200 order superfine powders be carried out continuous desulfurization through vacuum feeding under 220 degree states during regeneration.Waste old can be converted into 200 order ultra-fine grinding activated rubber powders (seeing technological process) through above-mentioned production process, realize recycling fully.The quality index of 200 superfine activated rubber powders is: pull apart and stretch productive rate〉570, hot strength〉18Mpa, tear strength〉65, you wear away (mm Shao Po 3/ 40m)<85, ash content<10.

---reinforced---------dedusting---storage---continuous desulfurization regeneration, continuous desulfurization regeneration belong to the regeneration of back and recycle the stage pulverizer, are the subsequent techniques of technique of the present invention in the negative pressure sorting in the technological process of reclaiming: 20 order rubber powders.

Activator 480 and softening agent C8H6O, desulfurizing agent Diphenyl disulfide compound are salable item on the market.

The chemical analysis of activator 480: the mixture of multiple alkylphenol sulfide.Structural formula: proterties: dark brown dope outward appearance dark brown dope, manufacturer is that sincere auxiliary reagent factory is converged in the Wen County, the softening agent molecular formula is C8H6O, and Co., Ltd produces by the positive sharp chemical industry in Datian County, and desulfurizing agent is to have many enterprises to sell on the Diphenyl disulfide compound market.
