Description
Technical field
The invention belongs to waste utilization and the technical field of plastic cement race track, provide it is a kind of containing waste-tyre rubber-powder it is low at
This plastic cement race track and preparation method.
Background technique
With economic sustained and rapid development, living standards of the people are continuously improved, and reconstruct sports Ground with plastic cement
Layer is more prevalent.Many cities cover on the exposed athletic ground of original school's loess with plastic cement race track, on the one hand help
It is renovated in fugitive dust, in addition can also improve moving condition.Plastic cement race track has flatness is good, compression strength is high, hardness is elastic to fit
When the characteristic of, stable physical property, is conducive to the performance of sportsman's speed and technology, effectively improves sports achievement, reduction is fallen
Hurt rate, has been widely used for sporting venue or playground etc..
Plastic cement race track is also known as round-the-clock athletics tracks, mainly by base polyurethane prepolymer for use as, admixtured polyether, rubber grain,
The composition such as EPDM rubber grain or PU particle, pigment, auxiliary agent, filler.Wherein, the booming of automobile industry leads to waste tire rubber
The processing of glue has become global problem, and waste tire is known as " black pollution ", how these waste tires is recycled
It gets well, makes good use of, turns waste into wealth, turning harm into good, this is the very severe problem that we face, and is used for plastic cement race track
It is highly desirable recycling mode.
Traditional plastic cement race track causes preparation cost higher because raw material and preparation process are undesirable, this is also to restrict plastic cement
An important factor for runway development and application.Therefore, the recycling processing technology for being effectively improved waste tire becomes very important one
Content.Produce three kinds of finished products: blob of viscose, micelle, rubber powder using waste tire, existing plastic cement race track mainly use micelle and
The levels of audit quality of rubber powder is uneven, and cost recovery is higher.Therefore, it studies and waste tire rubber preparation modeling is more rationally recycled in application
The technology of glue runway is concerned.
Chinese invention patent application number 201510908326.9 discloses the side that a kind of thermosol depolymerization waste tire is rubber powder
Method, which passes through the ionic liquid and hydrogen supply dissolvent of the efficient disaggregation of waste and old tire construction of selection energy, by waste tire and ion
Liquid and hydrogen supply dissolvent are added in reaction kettle, carry out thermosol depolymerization in a mild condition；Then by resulting reaction product with four
Hydrogen furans washes out, and can obtain the mixed liquor of tetrahydrofuran soluble matter, tetrahydrofuran, ionic liquid and naphthane and residual by filtering
Slag, mixed liquor can obtain mixture by rotating solvent-recoverable；Water sedimentation is finally added into mixture and filters can obtain glue
The mixed solution of the mixed solution of powder and ionic liquid and naphthane, ionic liquid and naphthane is reusable.The invention is deposited
Defect be waste tire recycle technical process it is more many and diverse, economic benefit is poor.
Chinese invention patent application number 201611049671.2 discloses a kind of plastic cement race track and preparation method thereof, according to weight
Measure part, the B component including 30 ~ 50 parts of component As and 50 ~ 70 parts, component A is made of following compositions: toluene di-isocyanate(TDI) gathers
Ethoxylated polyhydric alcohol；B component is made of following compositions: crosslinking agent, filler, pigment, thickener, antioxidant.But the defect of the invention
Be plastic cement race track preparation cost it is higher, and be not able to achieve recycle waste polymer material effect.
In conclusion waste tire causes environmental pollution and the wasting of resources, the economic benefit of recycling in the prior art
Difference, and there are the higher defects of preparation cost for plastic cement race track, therefore develop a kind of waste tire rubber recycling preparation of low cost
Plastic cement race track, have great significance.
