Description
Technical field
The invention belongs to sports facility technical fields, and in particular to a kind of environment-friendly type mixing plastic cement race track and its preparation side
Method.
Background technique
According to factual survey, entire Huidong County about generates 300t shoes industry waste material daily.Shoes industry leftover pieces account for about total material quantity
20%-40%.Major part shoes manufacturing enterprise, Huidong County, it is relatively simple to the management of shoes industry waste material rough, without written spoiled products management
Article do not store classifiedly shoes industry waste material, increase the difficulty of waste material subsequent processing.Local shoes industry waste disposal mode compared with
To be single, most of outward transport processing, and the enterprise that the local shoes industry waste recovery without large-scale utilizes.Still have in waste material big
The waste material of part recoverable is landfilled processing.In this case, government should reinforce the guidance to enterprise, organize and coordinate phase
Pass department, make shoes industry waste material obtains reasonably handling disposition, and enterprise should improve the yield that production technology reduces waste material, formulate
Shoes industry waste management system reinforces the management to shoes industry waste material.Legal power generation by waste combustion, cement kiln synergic processing or planning industry park
Area carries out resource utilization to shoes industry waste material, walks the direction that sustainable development route is future development.
It mainly include polyurethane (PU) waste material, ethylene and vinyl acetate copolymer (EVA) etc. in shoemaking waste, wherein
Polyurethane (PU) waste material mainly based on foamed product, there is soft, hard, semi-rigid foam.P U is due to function admirable and purposes
Extensively, development is very rapid, and waste is also more and more, therefore the recycling of its waste product can not only effective protection ring
Border reduces pollution, and can save resource, turns waste into wealth.It is, in general, that the method for recycling waste polyurethane has physical method, changes
Method and energy regenerating.Wherein energy regenerating is that burn under certain condition to PU waste material a large amount of thermal energy of generation recycle,
If but will not exclusively generate toxic and harmful gas in burning process fuel simultaneously and cause secondary pollution, thus should not use.Physics
Method is simple and easy, technical maturity, but the product properties that recycling comes is poor, is only suitable for making low grade products, and aging is eliminated more
Fastly.Chemical recovering method technical matters is relative complex, and industrialization is mature later, and new biodegrading process still continuously emerges up to now,
Some biodegrading process are still in the laboratory research stage, but good foam property made from final regenerant.
The crosslinked foaming material of ethylene and vinyl acetate copolymer (EVA) has high-flexibility, impact resistance, weather-proof
The advantages that with anti-exposure, is widely used in fields such as sound insulation, vibration damping, heat preservation, toy, movement shoes materials.EVA waste material tool
There is certain recycle value, therefore local footwear industry has had the recycling route of comparative maturity to EVA waste material.Recycling
It is large grained waste material that EVA bottom plate waste material is generally carried out cutting and grinding by route, enters back into double screw extruder, melts, draws
It is cut into fine granularity after silk, cooling, the raw material for regenerating EVA bottom plate is can be used as, the original of other purposes can also be made
Material.
Shoes industry waste material safely and effectively dispose be it is very urgent, need to find out effective Countermeasures for Disposal as early as possible.Dew at present
Common several processing modes such as its stacking, open incineration, landfill in the presence of pollution environment, damage ecology, endanger population health,
The problem of waste of resource.Implement the resource utilization of shoes industry waste material, guarantees that the waste material that can be recycled obtains effectively as far as possible
It utilizes, just seems especially urgent in the case where shortage of resources, pressure are increasing.In short, realizing the recycling of shoes industry waste material
It utilizes, is allowed to reenter the circulatory system, be only the basic place for establishing cleaning, green, environmental protection, sustainable development.
In the prior art, plastic cement race track is under the higher weather of temperature, is easy expanded by heating, influence runway elasticity and
The comfort of movement；The reduction of the screen resilience of plastic cement race track simultaneously, also improves the probability of sportsman's ankle injury.
