Description
Technical field
The invention belongs to sport field paving material fields, and in particular to a kind of wear-resisting antiskid high life environment friendly plastic rubber
Runway and preparation method thereof, international IPC code are E01C13/04.
Background technique
With the rapid development of modern social science technology, and attention of the country to sports, Chinese sports cause
It is flourished.In face of the increasing of government investment dynamics, national education sector and non-education sector sports equipment with
Unprecedented speed development, sporting fields and facilities new product continues to bring out, so that the development of sports equipment is maked rapid progress.Body
It educates place and facility is the material base for carrying out sports, importance exists《People's Republic of China's national sports method》,《Entirely
People's fitness program outline》With《Public cultural and sports facilities regulations》Etc. all embodied in rules and regulations.Further, since national
Nationwide fitness programs are advocated energetically, oneself becomes a kind of life style of people for present body building, and people are to body-building and athletics sports place
The requirement of facility also increasingly improves.The synthetic court of coal ash place till now always, sport are developed to from initial soil site
The condition of facility is improved constantly.Early in year, it is long that the material-paving containing polyurethane compositions is gone out a rice by u s company
Horse racing plastic cement race track.Polyurethane plastic is started for being laid with athletic ground and runway.Hereafter, plastic cement race track is each in the world
State's rapid development.The development of plastic cement race track was rapider in recent years, and laying amount increases year by year, and range is from original Physical Culture and Sports Commission
System is expanded to the educational systems such as large, medium and small.
School physical education deepens continuously with what Healthy Curriculum standard was promoted, school sports equipment be equipped with catalogue popularization with
Implement, and country is big for the continuous power of education sector investment, the schools of various levels and categories are by construction and upgrading school sports ground
Ground column arrived agenda, wherein be laid with high standard plastic sports ground be then school carry out place transformation key project it
One.At present each school of China all by Accelerating The Construction or oneself built plastic sports ground, but for various reasons, cause
The quality and performance of plastic cement race track cannot reach state specified standards, therefore some schools athletic ground is deposited during use
In certain quality problems and security risk, the shortening of place service life will cause, product quality is inferior, it is possible to cause state
The waste of family's investment and the generation of student's injury accident.
Plastic cement race track is broadly divided into following three types：1, mixed type plastic track is also known as traditional plastic cement race track,
Due to being limited by its synthesis and construction technology, there is following problems for the type plastic cement race track：Manufacture installation and use process
Present in not environmentally factor, manual operations lead to that runway hardness and coefficient of friction are not easy to control, it is poor, existing to complete surface evenness
Field construction is it is difficult to ensure that thickness and homogeneity；Its design feature causes runway easily to fall the drawbacks such as grain, easy to foaming, poor flexibility.2, thoroughly
Gas type plastic cement race track introduces China in initial stage in 2000, since the type plastic cement race track uses mechanized construction technique, construction speed
Degree is fast, and cost is lower, is widely used in the occasion based on training, teaching such as middle and primary schools in recent years.But due to the runway
Sport dynamics performance is poor, anti-sting and wear-resisting property are relatively weak, so not being suitable for the athleticses such as professional sports venue field
Institute.Simultaneously as market competition unordered in the limitation and industry of China's material technology leads to the product quality and environmental-protecting performance
It is difficult to ensure.3, rubber Precasting synthetic surface track is the high-end product of plastic cement race track, and there is good movenent performance and environmental protection to pacify
Quan Xing.Currently, the excellent movenent performance of pre-fabricated rubber running track, environmental-protecting performance and reasonable cost performance are in China by special
The approval and attention of industry mechanism and society.
106280098 A of Chinese patent CN provides a kind of track and field runway, is able to solve existing production to a certain extent
Product cannot combine lacking for anti-nail performance, elastic force, intensity, toughness and damping effect and the many-sided effect of nonhazardous environmental protection
It falls into, combines elasticity, shock absorption, environmental protection etc..The patent mainly uses four kinds of substances to assemble, i.e., PVC paste resin, to benzene
Diformazan dioctyl phthalate, calcium zinc stabilizer, azodicarbonamide are as primary raw material.The product have anti-nail performance, elastic force, by force
Degree, toughness and the good effect of damping effect, good weatherability when application, service life are up to 10 years or more, while pre-formed being applied
Work is convenient, and whole pollution-free environmental protection is renewable, can be widely applied to sport field paving material field, especially environmentally friendly
In track and field runway, with wearability, resistance to soiling, the feature of environmental protection is good, anti-flammability is high, mute, impact resistance, the effect of antiskid, shock-absorbing, protects
Many advantages, such as hindering sportsman's safety, being free of any harmful substance.
Although technical solution provided by 106280098 A of Chinese patent CN can improve runway to a certain extent
Comprehensive performance, but it is in wearability, skid resistance and it still needs further improvement on the high life, and then adapts to the race of higher standard
Road requirement.
Therefore, it is this that the wearability, skid resistance and high life of runway how are further increased in prior art basis
The striving direction of field researcher, wearability, skid resistance and high life if can be further improved runway can solve
The technical issues of certainly good existing runway is difficult to adapt to the runway requirement of higher standard.
