Abstract
The present invention relates to odorless tire regenerated rubber and a preparation method thereof. The production of the tire regenerated rubber by using waste tires is considered as a matter of 'changing wastes into valuables, and benefiting both the country and people'; however, in the present tire regenerated rubber and the production process thereof, a plurality of problems exist, such as the problems that the product has a bad odor, the application is limited, the processes of production, transportation and use pollute the environment, and when the product is applied to the production of imitation leather bottom sheets, a special adhesive used in the production of leather shoes yellows the imitation leather bottom sheets and influences the appearance of the leather shoes, or the performance indexes of the product can not meet the application requirements even though the product is odorless. The present invention overcomes the defects existing in the prior art. The preparation method of the odorless tire regenerated rubber is characterized in that an activating agent, rosin, pine tar, solid pine tar and water are added into rubber powder during desulfurization, all the performance indexes of the obtained odorless tire regenerated rubber without odor conform to the national standard specifications in China, and the odorless tire regenerated rubber having wide adaptability can be blended into various rubber products.
Description
Technical field
The invention belongs to a kind of whole tire reclaim rubber and production technique thereof, particularly relate to a kind of no stink whole tire reclaim rubber and preparation method thereof.
Background technology
Owing to reasons such as resource scarcitys, rubber raw materials holds at high price for a long time.Produce whole tire reclaim rubber with junked tire,, can eliminate the junked tire pollution on the environment simultaneously, and be considered to the thing of " turn waste into wealth, benefit the nation and the people ", in Economic development, play an important role because of regenerated rubber energy part instead of rubber.Yet traditional whole tire reclaim rubber has two kinds of situations, and a kind of situation is that every performance index meet the GB/T13460-1992 national Specification, but frowziness; Though another kind of situation is not have stink, every performance index do not reach the GB/T13460-1992 national Specification.Under first kind of situation, at first the hazardous and noxious substances of using because of production process has caused pollution to environment; Next is that product itself has stink, in transportation and use environment is polluted on the one hand, uses on the other hand and has been subjected to very big restriction, has made it tangible limitation; In addition, when this whole tire reclaim rubber is used to produce leather shoes egative film material---when imitating the leather egative film, the special-purpose adhesive that uses in the leather shoes production process can cause the yellowing of imitative leather egative film, directly influences the visual appearance of leather shoes.Under second kind of situation,, can not satisfy application requiring in most occasions because every performance index do not reach the GB/T13460-1992 national Specification.
Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, proposed a kind of no stink whole tire reclaim rubber and preparation method thereof.This no stink whole tire reclaim rubber production process has been abandoned hazardous and noxious substances, selects nontoxic industrial chemicals for use, and environment is not polluted; Product does not have stink and every performance index meet the GB/T13460-1992 national Specification, can be applicable to automobile, boats and ships, machinery and daily necessities various fields, when being used to produce leather shoes egative film material---when imitating the leather egative film, the special-purpose adhesive that uses in the leather shoes production process can not cause the visual appearance of imitating leather egative film yellowing and influencing leather shoes, especially for the production of various light leather shoes, this advantage is more outstanding; And this no stink whole tire reclaim rubber adapts to versicolor surface printing processing.
The present invention solves the technical scheme that its technical problem takes: a kind of no stink whole tire reclaim rubber, its every performance index meet the GB/T13460-1992 national Specification, activator, rosin, Stockholm tar, solid Stockholm tar and water have been added in the rubber powder during desulfurization in the sulfur removal technology of its preparation method, thereby sense of smell does not have stink, promptly have only the rubber original flavor and do not have the peculiar smell of conventional tyre regenerated rubber, but fusion is in various rubber items.
A kind of preparation method who does not have stink whole tire reclaim rubber comprises coarse crushing, in small, broken bits, desulfurization and refinery practice step, has added activator, rosin, Stockholm tar, solid Stockholm tar and water during desulfurization in the rubber powder.Described activator can be 420 activators, and this moment, rubber powder batching to be desulfurization adopted following prescription: 100 parts of waste tyre rubber powders, 0.15～1.0 part in 420 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 in water; Wherein in the rubber powder the preferential addition of 420 activators be rubber powder 0.16%～0.95%, the preferential addition of rosiny be rubber powder 1.25%～3.4%, the preferential addition of Stockholm tar be rubber powder 3.6%～11.3%, the preferential addition of solid Stockholm tar be rubber powder 0.8%～2.8%, the preferential addition of water is 2.9%～8.5% of rubber powder; Wherein in the rubber powder optimum addition of 420 activators be rubber powder 0.55%, the rosiny optimum addition be rubber powder 1.53%, the optimum addition of Stockholm tar be rubber powder 4.2%, the optimum addition of solid Stockholm tar be rubber powder 0.93%, the optimum addition of water is 5.6% of rubber powder.Described activator also can be 450 activators, and this moment, rubber powder batching to be desulfurization adopted following prescription: 100 parts of waste tyre rubber powders, 0.15～0.8 part in 450 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 in water; Wherein in the rubber powder optimum addition of 450 activators be rubber powder 0.43%, the rosiny optimum addition be rubber powder 1.53%, the optimum addition of Stockholm tar be rubber powder 4.2%, the optimum addition of solid Stockholm tar be rubber powder 0.93%, the optimum addition of water is 5.6% of rubber powder.
No stink whole tire reclaim rubber and preparation method thereof, not only solved in production, transportation, the use pollution to environment, and there is not stink and every performance index meet the GB/T13460-1992 national Specification because of product, make it to have adaptability widely, but fusion comprises in the various outlet rubber items in various rubber items.Simultaneously, fusion is used in various rubber items, part has substituted natural rubber and various synthetic rubber, thereby can reduce the production cost of rubber item greatly, improve the economic benefit of rubber item manufacturing enterprise, and production whole tire reclaim rubber, the purpose of " turn waste into wealth, benefit the nation and the people " have really been realized.Therefore, no stink whole tire reclaim rubber of the present invention will substitute, eliminate traditional whole tire reclaim rubber, and its preparation method will become whole tire reclaim rubber production technology trends.
