Abstract
The present invention relates to a manufacturing method of plastic tracks and sports grounds. The mixed plastic particles of polyurethane plastic particles and adhesive plastic particles or other plastic particles are laid with layers on an asphalt foundation or a cement foundation; the plastic particles of an old tyre are also mixed; a colored plastic particle layer is also coated on an upper layer or a surface layer. The present invention is characterized in that the polyurethane of a plastic layer has a single component; the plastic particles of a novel ethylene propylene terpolymer are adopted as the adhesive plastic particles; the polyurethane with the single component is prepared from isocyanate, polyether polyalcohol and a chain extender according to proportional arts and a prescribed synthetic technology. A plastic track manufactured by the present invention has the advantages of no drop of the plastic particles, no dehiscence of the plastic layer, long service life and good application prospect; the quality reaches a technical requirement specified by the International Track and Field Union.
Description
One, technical field:
The present invention relates to the preparation method on a kind of plastic cement race track, athletic ground, belong to sports ground paving class in the building.
Two, background technology:
At present; domestic plastic cement race track all is to adopt dual-component polyurethane and a small amount of black micelle to mix; the shop water on pitch or cement ground, spread one deck dual-component polyurethane then after, sprinkle red micelle; this appellation " tower is worked as " runway; the surface red micelle very easily comes off, and is easy to wear out, and peels off, ftractures; application life is short, becomes the problem that is difficult to overcome.
Three, summary of the invention:
Purpose of the present invention discloses the preparation method on a kind of plastic cement race track, athletic ground, and the plastic cement race track of composition can overcome the defective of prior art, the elastic body plastic cement basic unit of composition, have hole, can breathe freely, seep water, making the ground internal stress is zero, micelle does not come off, and glue-line does not ftracture, long service life.
The present invention is achieved like this, a kind of plastic cement race track, the preparation method on athletic ground, on pitch or concrete pedestal, polyurethane is laid in layering, cementing agent mixes with other micelles, what have also dopes the old tire micelle, the coloured glue granular layer of one deck is also answered on upper strata or top layer, the polyurethane that it is characterized in that plastic layer is monocomponent polyurethane, the micelle of bonding adopts ethylene propylene terpolymer, and described monocomponent polyurethane is made up of following material: isocyanates: toluene di-isocyanate(TDI), diphenyl methane-4.4 ' vulcabond, the many based isocyanates of polymethylene, 1.6 choose any one kind of them in the hexamethylene diisocyanate or two, three kinds of mixing; PPG: comprise polyether Glycols, polyether-tribasic alcohol, polyethers tetrahydroxylic alcohol; Chain extender, the recipe ratio of each material: isocyanates 10%～32%, PPG 90%～60%, chain extender 0～8%.Ethylene propylene terpolymer is a prior art, and this case is not described further.
Monocomponent polyurethane synthesis technique step is: add isocyanates in proportion in reaction pot, heat, add PPG and chain extender gradually, temperature is controlled at 70～105 ℃, in 2～4 hours reaction time, carries out blowing behind synthetic the finishing.
The ethylene propylene terpolymer particle size analysis is at 0.5mm～2mm or the particle diameter of pulverizing regulation as requested micelle, hot strength 0.3Mpa～1.0Mpa, elongation rate 300%～700%.
With the plastic cement race track of above material made, can reach the object of the invention fully, promptly micelle does not come off, and glue-line does not ftracture, and long service life meets International Track and Field Association to technical requirements that plastic cement race track proposed.
Four, description of drawings:
Accompanying drawing 1 is embodiment 1 a plastic cement race track structure diagrammatic cross-sectional view.
Accompanying drawing 2 is embodiment 2 plastic cement race track structure diagrammatic cross-sectional view.
Five, the specific embodiment:
Embodiment 1: with monocomponent polyurethane and ethylene propylene terpolymer is the plastic cement race track that primary raw material is made a kind of four-layer structure.(1) be ground layer, pitch or cement structures all can, surface cleaning is clean; (2) bottom adopts monocomponent polyurethane, sprays with flush coater, as the setting course of basic unit's glue granular layer; (3) basic unit adopts monocomponent polyurethane, rubber micelle or old tire micelle mixing micelle, reaches specific thickness, with spreading machine or manually be paved into; (4) surface layer is the micelle that the Ethylene Propylene Terpolymer micelle of 0.5mm～2mm mixes with coloured monocomponent polyurethane and small particle diameter, and with the flush coater spraying for several times, treating becomes a kind of plastic cement race track after dried the condensing.
Embodiment 2: identical with method with embodiment 1 front four-layer structure, have with monocomponent polyurethane at the 4th laminar surface spraying one deck, spread one deck regulation particle diameter Ethylene Propylene Terpolymer micelle again, the coloured monocomponent polyurethane of spraying one deck becomes the 5th layer of structure (5) on granule again, waits to do the back and is another plastic cement race track.
A kind of plastic cement race track that the present invention makes, there is hole in elastic body plastic cement basic unit, can breathe freely, seep water, and making the ground internal stress is zero, and runway surface micelle does not come off, and glue-line does not ftracture, and long service life reaches the requirement of International Track and Field Association to plastic cement race track.
