Abstract
The invention provides a manufacturing method for fragrant high-tenacity tire reclaimed rubber. The method comprises the production processes of: material selection and screening, blending, desulfurization, open milling, kneading, refining and profiling. The method is characterized in that: rubber powder is screened to obtain rubber powder with a particle size of 8-12 meshes; in the blending process, 100 parts of rubber powder, 15-20 parts of solid coal tar, 0.3-0.5 part of a 480 activator, 0.4 part of an antioxidant RD, 0.7-2.2 parts of rosin, 0.8-2 parts of pine tar and 14-18 parts of water are blended; and in the desulfurization process, the pressure is up to 2.1MPa, the reaction temperature is 195-205DEG C, and the reaction time is 85min. The manufactured fragrant high-tenacity tire reclaimed rubber has the beneficial effects that: 1. the physical properties are greatly improved; 2. it not only has no odor, but also has certain fragrance; 3. the processability is improved; 4. toxic and harmful substances are significantly reduced; and 5. energy is saved.
Description
Technical field: the present invention relates to a kind of manufacture method of whole-tyre reclaim, particularly a kind of manufacture method of odor type high-tenacity whole-tyre reclaim.
Technical background: the manufacture method of existing whole-tyre reclaim is mainly by junked tire being rolled to powder, screen, be mixed, desulfurization, open refining, refining, refining again, die mould and become reclaimed rubber.As Chinese patent CN250621C discloses a kind of odorless tire reclaimed rubber and preparation method thereof; Its feature is, in sweetening process, in rubber powder, to add 420 activators, rosin, Stockholm tar, solid Stockholm tar and water; Its proportioning is: 100 parts of damaged tires; 420 0.15～1.0 part, activators; 1.2～3.5 parts of rosin; 3.5～11.5 parts of Stockholm tars; 0.8～3.0 part of solid Stockholm tar; 2.7～8.8 parts, water; Its objective is the properties of removing the stink in regenerated rubber and making regenerated rubber meet GB T13460-1992 GB; Product after tested index is respectively as follows: moisture is 0.82%, ash content is 7.9%, acetone extract is 10.3%, tensile strength is that 7.2Mpa, tensile yield are 320%, mooney viscosity is 80.The effect of the method is: on the smell of regenerated rubber product, made obvious improvement, product test index also mostly reach GB the standard of T13460-1992 GB.But generally, be not very desirable, because it is increasing that the consumption of present regenerated rubber product accounts for the ratio of total consumption, and to the physicals of regenerated rubber product, require more and more higher in various uses, as produce high-quality tire, tyres for passenger cars, load-carrying and light truck tire, bus tyre, special vehicle tire etc., if only reach GB the standard of T13460-1992 GB be to be difficult to meet the needs of producing now, also wish that in addition product does not only have stink but also will be with certain requirements such as fragrance, obviously, existing method has been difficult to be competent at.
Summary of the invention: the object of the invention is to, the deficiency of ever-increasing needs during the product of producing for existing tyre reclaimed rubber manufacturing method has been difficult to meet to use, and propose a kind of good physical performance, have the manufacture method of the odor type high-tenacity whole-tyre reclaim that certain fragrance and hazardous and noxious substances significantly reduce.
By following technical proposals, can realize object of the present invention, a kind of manufacture method of odor type high-tenacity whole-tyre reclaim, it comprises following production process: selection screens～is mixed～and desulfurization～drive refining～kneading～refining～die mould, it is characterized in that, the granularity of screening rubber powder is 8～12 orders; In the operation that is mixed, the proportioning of each component is: 100 parts of rubber powders; 15～20 parts, solid coal briquette tar; 480 0.3～0.5 part, activators; 0.4 part of anti-aging agent RD; 0.7～2.2 part of rosin; 0.8～2 part of Stockholm tar; 14～18 parts, water; In desulfurization process, pressure is up to 2.1MPa, 195～205 ℃ of temperature of reaction, 85 minutes time.
For making product there is fragrance and improving its processing characteristics, in desulfurization with open between refining operation and increased mixed processes, in the sizing material after desulfurization, drop into litsea cubeba oil and mix.
Litsea cubeba oil drops into by proportioning 1～1.5 deal.
For reducing the venomous injurant in product, be beneficial to environment protection, activator is 480.
Anti-aging agent is anti-aging agent RD.
This product can reach following indices after testing:
Its venomous injurant is through CTI detected result:
Effect of the present invention is: 1, physicals significantly improves, tensile strength >=the 17Mpa of its A level product, elongation rate of tensile failure >=500, tensile strength more than currently available products is that the physicals that 7.2Mpa, tensile yield are 320% exceeds a lot, and its reason is: the rubber powder granularity of (1), present method is 8～12 orders; (2), in desulfurization process, pressure is 2.1MPa, 195～205 ℃ of temperature of reaction, 85 minutes time; (3), the proportioning of each component is different with the proportioning of existing component.2, odorless not only, and there is certain fragrance, this is mainly to have used in present method Stockholm tar, rosin, litsea cubeba oil; 3, improved processing characteristics, this is mainly, has increased mixed processes in Production Flow Chart, in the sizing material after desulfurization, drops into litsea cubeba oil and mixes, and adds litsea cubeba oil to be conducive to improve the processing characteristics of sizing material after desulfurization; 4, venomous injurant significantly reduces, and is beneficial to environment protection, and this is 450 activators that present method is used 480 activators to substitute to pollute 420 high activators or have pollution; 5, saved energy, because the rubber powder granularity of present method is 8～12 orders, thicker than prior art 20～30 objects, can reduce the number of times of pulverizing, save energy.
