Description
Technical field
The present invention relates to athletic ground runway facility technology field, more particularly to from knot line without particle environment-friendly type plastic rubber runway
Laying method.
Background technology
With the development of social economy, environmental issue is increasingly severe, and people get over to the requirement of sports facility usage safety performance
Come higher.At present the country plastic cement race track more use dual-component polyurethane oleaginous system, belong to (TDI+MDI)-MOCA- heavy metals from
Muonic catalysis agent system.There is free TDI (toluene di-isocyanate(TDI)) in runway, free TDI can be caused beyond 0.5% to human body
Injury；Crosslinking agent does not block MOCA has toxicity, is suspect carcinogen；Heavy metal ion (mercury, lead, zinc) is toxicant, laying
During the volatile organic solvent such as benzene,toluene,xylene that uses etc. be also toxicant, therefore, the system is not inconsistent cyclization
Guaranteed request.
For meet the requirement of environmental protection, people begin one's study environmentally friendly track material, during such as publication No. is CN 103666233A
State's patent of invention discloses a kind of vapor-permeable type polyurethane plastic runway cover glueing material, belongs to runway technical field of construction, it
It is 1 by mass ratio：3~4 first component and second component composition, first component is polyisocyanates, the PPG by environment-friendly type
And auxiliary agent is in the prepolymer containing terminal isocyanate groups obtained in 70~80 DEG C of reaction kettle for reaction 3~4 hours.Second component includes
The PPG of three-functionality-degree, inorganic filler, pigment, plasticizer, curing agent, antioxidant and ultra-violet absorber etc..The hair
The bright plastic cement race track surface particles for obtaining are difficult for drop-off, surfacing, the quality and its service life that improve plastic cement race track, make
The qualification rate of plastic cement race track brings up to more than 95% by current 82%, reduces manufacturing cost and use cost, and, the hair
Bright raw material used is ep-type material, belong to environmentally friendly material, it is to avoid environmental pollution.But, the invention is still adopted
With bicomponent system, it is necessary to scene weighs dispensing, stirs in proportion, this link is very easy to error, once error
Serious quality problems can be caused.Additionally, the invention plastic cement race track non skid matting still uses EPDM or PU particles, it is viscous by grain
Connect or the mode of grit blast bonding is attached to reinforcement layer surface, use the easy threshing of surface particles after a period of time, and particle point
Cloth is uneven to cause skin-friction coefficient also uneven, influences the performance of sportsman；Particle detachment is also resulted in and is sprayed on particle surface
Shunting paint marking disappear, influence the use of runway, and very unsightly.

Powder and quartz sand are sufficiently stirred for being formed from knot lamina material mixed slurry, are sprayed on mixed slurry by the air pressure of flush coater dry
Solid enhancement layer on, allow mixed slurry to be integrated with enhancement layer seamless combination.By the quartz sand and EPDM particles that are sufficiently stirred for
Rubber powder quilt cover enamel-cover wraps up in (because quartz sand and EPDM particle rubber powder proportions are lighter, the two is easily combined in finish paint), and by spray
The pressure of painting machine permeate completely in formed in the enhancement layer of 2mm thickness one from skinning non-slip texture.
Obtained runway bright-colored, anti-skid wearable, sustains its quality through age from lamina is tied without particle, thoroughly solves modeling at present
Glue runway surface uses the particles stick caducous puzzlement of technology particle, and durability is preferably lifted；Due to from knot line without
Particle environment-friendly type plastic rubber runway surface texture is full, uniform, is not in the unstable sensations such as underfooting loosening, contributes to motion
The performance of member, the competitiveness of lifter motion person；Also there is non-maintaining, anti-aging, colour-fast, moderate, product the stretching of elasticity
Intensity is high, long service life the advantages of, property indices meet the technical requirements of International Track and Field Association and GB/T14833-2011.Run
The performance indications in road are as shown in table 1-3.
Runway prepared by the present invention of table 1 prepares comparing result with common bi-component track performance
The performance of runway specifies comparative result with International Track and Field Association in the present invention of table 2
The runway and common bi-component runway poisonous and harmful chemical composition content comparative result prepared in the present invention of table 3
Knowable to table 1, table 2, the runway physical motion performance indications in the present invention are high, add from knot line technique, surface line
Clear it is clear, do not fall particle, low temperature be not hardened, wearing coefficient it is high；Tensile strength and elongation rate of tensile failure are higher, increase the service life.
From the data of table 3, track material of the invention more conforms to national environmental protection with single-component water-based materials chemistry performance
It is required that.
Embodiment described above only expresses one embodiment of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Shield scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
