Reclaimed rubber or reclaimed-rubber-doped rubber or rubber-plastic composition product and production method thereof

Abstract

The invention provides reclaimed rubber or reclaimed-rubber-doped rubber or rubber-plastic composition product and a production method thereof, and relates to component A thermo-plastically produced, or/and component B ground at normal temperature, or A/B composition, or A- or/and B-doped rubber or rubber-plastic composition; the product is characterized in that, in terms of environmental protection, 3-5 g of A or/and B sample is taken, a polyester film is placed on at each of the top and boom of the sample, the sample is then placed on a vulcameter or a Mooney viscosity meter and is heated at 180 DEG C for 10 min, the sample is taken out and placed still at room temperature for not shorter than 5 min, the top and bottom polyester films on the sample are removed and stacked, the films are observed under a fluorescent lamp, yellow staining the polyester films is never darker than 101C or 601C on the national standard color (PANTONE) card, or/and the films never produce a characteristic offensive odor that is any one of or a combination of any of coal tar odor, pine tar odor, aromatic hydrocarbon oil odor and asphalt odor, or/and choking odor; the A/B composition is characterized in that the components A and B are premixed in any ratio in the weight ratio range of 95/5 to 5/95.

Description

technical field [0001] The present invention proposes a regenerated rubber or its mixed rubber or rubber-plastic composite product and its production method, which involves the implementation of four full-buckle combination methods of "full amount, green, high value, and energy saving" for waste rubber resources Under the framework, further improving the connotation of green and high-value physical properties of thermally regenerated rubber (component A) and normal temperature finely ground rubber powder (component B) belongs to the technical field of waste rubber resource regeneration. technical background [0002] Internationally speaking, the recycling of waste rubber has a history of hundreds of years. The main object of waste rubber regeneration is the waste tires used by automobiles, and waste tires have accounted for more than 60% of the total waste rubber products today. For the resource recycling of waste tires, the mainstream technical direction reflected in the l...

Problems solved by technology

[0006] ZL201010275839.8 also has deficiencies: the starting material put into the stirring heater is waste rubber coarse powder passing through a 5-40 mesh sieve. Compared with high-grade waste tires in this scheme, there must be a small amount in this material The steel wire that has not been stripped off by magnetic separation, the material after heat treatment needs to be decontaminated, and it will fall into the traditional high-energy-consuming filter or / and refining nest

[0012] However, the technical scheme of rubber powder and recycled rubber for proportional compounding recorded in "Encyclopedia of Practical Formulas for Rubber Products" implies the defect of tire disease that cannot be solved by this technical plan for proportional compounding, that is, the defects obtained from thermal regeneration so far. The environmental protection of regenerated rubber is still only in the pursuit of odorless at room temperature, and it is far from reaching the high standard of odorless in various downstream thermal processing processes. Even if the rubber powder preparation is the latest technology that has yet to be industrialized, For example, ZL200810083330.6, etc., although they have begun to propose four full-buckle combined method utilization methods of "full amount, green, high-value, and energy-saving" waste tire resources, they are still at the primary level, because it implies The thermal cracking of some high-grade waste rubber products (waste tires) is contrary to the idea of ​​the four-item full buckle combination method, and there is no synergy between the thermal method and the normal temperature method in the framework of the aforementioned combination method to prepare regenerated rubber products Technology

[0013] As mentioned above, in the prior art, it has not been found how to use regenerated rubber products with better physical properties than the existing thermal regenerated rubber and the rubber powder in the known technology to actively approach or even completely buckle various changes in the downstream The collection of physical properties of various rubber products, in order to achieve the purpose of using green high-value regenerated rubber as much as possible and using less new materials in the downstream product formulations; in addition, from the perspective of the newly emerging combined regeneration technology, there is also a need for more perfect solution
