Description
Technical field
The present invention relates to the regeneration production technologies that the regeneration technology of scrap rubber more particularly to a kind of scrap rubber produce sheet material.
Background technology
China is that the world's largest scrap rubber generates state.2009, China's waste tire yield 1.93 hundred million, weight was about
Up to 6,700,000 t.And its corresponding about 2,200,000 t of reclaimed rubber yield, waste Crumb rubber yield are about 220,000 t, at least 30% with
On waste rubber goods according to waste incineration or landfill, pollute environment, land occupation, waste of resource.
Although waste tire comprehensive utilization work in China's achieves certain effect, required not with current social economic development
It is adapted, the resource and environmental problem brought become increasingly conspicuous.Therefore, accelerate to promote waste tire comprehensive utilization, reduce rubber money
Source external dependence degree prevents environmental pollution, promotes damaged tire level of comprehensive utilization, oneself is very urgent.
Patent of invention CN1313522C discloses a kind of high-temperature continuous reproduction process of butyl rubber, according to the resistance to height of butyl rubber
The feature of temperature, using continuity method, in high temperature (temperature is controlled at 240-400 DEG C), normal pressure, hot oxygen, shearing force and softening solvent swell
Under effect, C-S, S-S chain or C-O-C keys in butyl rubber is made to crack rapidly, entire regenerative process is completed in machine cavity, then

Virgin rubber is consistent substantially, can arbitrarily be tuned between Mooney point 20-60, and control range is ± 5, and the use for meeting different user is wanted
It asks.But the problems such as that there are regeneration rates is not high for the technology, and swell rubber degree is not high.
For another example application for a patent for invention CN105418962A discloses a kind of continuous green regenerating of waste old two level and prepares grain
Shape modification regeneration rubber new method substitutes traditional level-one using the purely mechanic disconnected sulphur green regenerating new technology of Strong shear effect of two level
Desulfurization regeneration technology, without adding any chemical assistant and saving energy 40% in production process, production process is true with corresponding product
It is just environment friendly and pollution-free, while can act on obtaining the granular modification regeneration rubber product of diversification environment-friendly type with macromolecule modifier.It should
The reclaimed rubber product that method obtains equally exists the problems such as regeneration rate is not high, and swell rubber degree is not high.
For another example application for a patent for invention CN104526895A patents disclose a kind of vulcanized rubber powder production with waste tire
The method of reclaimed rubber, the function of extruding, the shearing, kneading of proposition twin-screw, the more change of focus utilization elastomer polymer
Reaction is learned, the plasticizing of elastic material high-performance and functionalization is carried out, i.e., is melted by the method for double screw extruder reactive extrursion
Melt blending and modifying, can quickly and easily prepare functionalization, systematization, the special reclaimed rubber for meeting different applications.The party
The reclaimed rubber product that method obtains equally exists regeneration rate and the not high problem of swell rubber degree.
