Abstract
The invention relates to an environment-friendly high-quality tyre reclaimed rubber manufacturing method, comprising the following steps: selecting waste radial tyre crowns, pulverizing the selected waste radial tyre crowns, screening, and adding composition of rubber powder, vegetable pitch, odourless pine tar oil, starex, activating agent and water while blending, wherein the activating agent is activating agent580; and carrying out banburying after desulfurizing, and carrying out rubber filtering after refining. Since the vegetable pitch, the starex, the odourless pine tar oil and other softeners as well as the activating agent580 are adopted, no pollution exists; especially the activating agent580 substitutes for the activating agen420 with high pollution or the activating agent450 with pollution, desulfuration is more thorough, and the reclaimed rubber has improved quality and no harmful substance and accords with the European Union standards; and since the materials are reasonably selected, and the technologies such as refining, rubber filtering and the like are adopted, the manufacturing of the high-quality reclaimed rubber is realized.
Description
Technical field
The present invention relates to a kind of tyre reclaimed rubber manufacturing method, relate in particular to a kind of environment-friendly high-quality tyre reclaimed rubber manufacturing method.
Background technology
From 2002, China is just replacing the U.S. became world's rubber first consumption big country, 2,800,000 tons of year consumption of rubber, and wherein import volume surpasses 73%, and this proves absolutely that China's natural rubber resource is very deficient.Therefore, China's rubber industry is when developing the synthetic rubber new variety energetically, improving the synthetic rubber ultimate production, and various places enterprise constantly pays attention to recovery and Utilization of Wastetires.Wherein damaged tire is produced reclaimed rubber, is one of effective way that remedies China's rubber sources shortage.At present, nearly 2,000,000 tons of China's reclaimed rubber output ranks first in the world.
Existing tyre reclaimed rubber manufacturing method mainly is by junked tire being rolled powder, screen, be mixed, desulfurization, opening refining, refining, refining again, die mould and become reclaimed rubber.The main application of reclaimed rubber is in rubber item is produced, and mixes sizing material by a certain percentage, and one replaces the sub-fraction rubber, and to reduce product cost, two improve the sizing material processing characteristics.The sizing material that is mixed with reclaimed rubber also can be made various rubber items.In China, the consumption of reclaimed rubber in tire is generally 5%, and the consumption in mechanicals is generally 10%～20%, and the consumption in low-grade goods such as heel, sole generally can reach about 40%.
Chinese patent CN1250621C discloses a kind of no stink whole tire reclaim rubber and preparation method thereof, in sulfur removal technology, add activator, rosin, Stockholm tar, solid Stockholm tar and water in the rubber powder during desulfurization, wherein activator is 420 activators, thereby sense of smell does not have stink, promptly have only the rubber original flavor and do not have peculiar smell, but fusion is in various rubber items.
Chinese patent CN101074302A discloses high-quality reclaimed rubber and preparation method thereof, main constituent is a rubber powder, 450 activators, solid coal tar tenderizer, rosin tackifier, through temperature is 240 ℃-260 ℃, pressure is 2.6MPa-3.0MPa, time is the reclaimed rubber that 1h produces with interior desulfurization, the tensile strength of its main physical index, tensile yield can improve 30%-60%, and the product ash, acetone extract, mooney viscosity has obvious decline, waste old can recover to reach more than 90% of performance of former vulcanized rubber through regeneration, be used for the production of various tires and rubber item, the product wear resistance is strong, and use is received the order long.
Chinese patent CN101235167A discloses a kind of production method of environment-friendly type regeneration glue, and the employing rubber seed oil is that activator, rosin are auxiliary agent, makes not contain poisonous objectionable impurities in the reclaimed rubber.
Therefore, do not see that at present environment-friendly high-quality tyre reclaimed rubber manufacturing method is arranged.
Summary of the invention
The present invention aims to provide a kind of environment-friendly high-quality tyre reclaimed rubber manufacturing method, and the reclaimed rubber when producing to reach high-quality tyre has high incorporation, can directly use reclaimed rubber when producing for conventional tyre, and the hazardous and noxious substances conformance with standard.
The technical solution adopted in the present invention is: a kind of environment-friendly high-quality tyre reclaimed rubber manufacturing method in turn includes the following steps:
(1) selection: select waste and old radial tyre crown, it is rolled powder;
(2) screening;
(3) be mixed: the composition when being mixed is rubber powder, plant asphalt, no stink Stockholm tar, starex, activator and water;
(4) desulfurization;
(5) banburying;
(6) open refining;
(7) refining;
(8) filter glue;
(9) refining again;
(10) die mould.
Described activator is 580 activators.
Described composition is as follows by weight ratio:
Rubber powder: 100 parts
Plant asphalt: 15-17 part
No stink Stockholm tar: 2.5-3.5 part
Starex: 0.7-1.3 part
580 activators: 0.3-0.7 part
Water: 10-14 part
Described banburying method is under 85 ℃-95 ℃, lasts 7min-9min.
Described filter gluing method is to filter at least 2 times through 100 mesh filter screens.
The invention has the beneficial effects as follows:
(1) because used plant asphalt, tenderizer and 580 activators such as the rosin that swims, no stink Stockholm tar, pollution-free, particularly 580 activators have substituted 450 activators that pollute 420 high activators or pollution is arranged, therefore, the reclaimed rubber of producing has very low objectionable impurities, meets European Union's standard, and, the reclaimed rubber of producing has only rubber that original flavor is arranged, and does not also have other smell.Its venomous injurant detects its result through SGS:
The poisonous and harmful substances detected result
| Project | Unit | European Union's standard | Detected result |
| Plumbous (Pb) | g/kg | ≤0.10 | 0.035 |
| Mercury (Hg) | g/kg | ≤0.10 | Do not detect |
| Cadmium (Cd) | g/kg | ≤0.30 | Do not detect |
| Sexavalent chrome (Cr 6+) | g/kg | ≤0.10 | Do not detect |
| Polybrominated biphenyl (PBB) | g/kg | ≤0.30 | Do not detect |
| Polybromodiphenyl ether (PBDF) | g/kg | ≤0.30 | Do not detect |
(2) owing to reasonably selected waste and old radial tyre crown, adopted the fine raw material, also guaranteed the consistence of main raw material, for realizing that producing high-quality reclaimed rubber has laid firm base.
(3) owing to adopted in conjunction with 580 high activators of sulphur content, make desulfurization more thorough, the tensile strength of reclaimed rubber, elongation rate of tensile failure are greatly improved, thereby have realized the high incorporation when producing high-quality tyre.
(4) owing to increased the banburying operation one, solve sizing material and mixed problems such as uneven, that fineness is not enough, also improved the quality of reclaimed rubber.
(5) owing to increased and filtered glue process together, further removed impurity (as sand grains etc.), outward appearance is more smooth, fine and smooth, does not contain particulate matter, and then has improved the quality of reclaimed rubber.
(6) owing to taked the measure of above-mentioned (2)-(5), and process control procedure passed through optimization, thereby it is high-quality to have realized that the reclaimed rubber of producing has, and its main performance index is better than " GB/T13460-2008 regenerated rubber "; For producing high-quality tire, as tyres for passenger cars, load-carrying and light truck tire, bus tyre, special vehicle tire etc., can mix the reclaimed rubber 20%～40% that the present invention makes, for producing conventional tyre, rubber item, as bicycle tyre, sole, rubber sheet gasket, sebific duct, elastomer connector etc., the reclaimed rubber that can all use the present invention to make.
Below be physical and chemical performance index and the GB/T13460-2008 contrast situation that adopts the environment-friendly high-quality reclaimed rubber of the present invention's production.
