Description
Technical field
The present invention relates to the technical field of athletic floor, more particularly, to a kind of aqueous half prefabricated high-environmental athletic floor and
Its construction method.
Background technique
Currently, being to make extensively in the world at present using water-based acrylic resin as the acrylic acid court material of main film forming substance
Court surface paver, this kind of product have many advantages, such as that aqueous, environmentally friendly, nontoxic, odorless, good weatherability, wearability are good.
Prefabrication type athletic floor need to have flexibility appropriate and impact absorbing ability, to increase the comfort of Athletess, reduce
Sports fatigue reduces the probability of movement tumble injury.
Existing Authorization Notice No. is that the Chinese patent of CN202644936U discloses a kind of athletic floor, including foaming layer,
The surface layer for being covered in PET plastic layer above foaming layer and being covered in above PET plastic layer, the foaming layer is from top to bottom successively
Including the first foamed buffer layer, stabilized zone and the second foamed buffer layer；The surface layer, PET plastic layer, the first foamed buffer layer,
Stabilized zone and the second foamed buffer layer synthesize an entirety by physical thermal.PET plastic is set between surface layer and foaming layer
Layer, improves the impact resistant strength and high and low temperature resistance of athletic floor；Two-ply foam buffer layer is set in foaming layer and is carried secretly
Glass chopped strand mat layer improves the cushion performance and elasticity of athletic floor, and anti seismic efficiency is good, long service life.
When traditional prefabrication type sports ground is laid with above-mentioned athletic floor, typically monolith place mat, in later period splicing
It is local that cracking hollowing easily occurs, it causes later maintenance cost big, a large amount of solid waste rubbish is caused when renovating place, therefore need
It is further improved.
Summary of the invention
It is an object of the present invention to provide a kind of aqueous half prefabricated high-environmental athletic floors, with crack resistence excellent performance
Effect.
Foregoing invention purpose of the invention has the technical scheme that
A kind of aqueous half prefabricated high-environmental athletic floor including bottom, the fiberglass layer above bottom, is located above fiberglass layer
Middle layer and the surface layer above middle layer, if the bottom includes the precast slab unit of dry splice, the precast slab unit
Top surface on offer several for carrying the circular holes of filler, the circular hole runs through the top and bottom of precast slab unit.
By using above-mentioned technical proposal, when surface of base mats formation athletic floor, by circular hole and contiguous prefabricated
Filler is filled in gap between plate unit, precast slab unit is not only bonded in surface of base after filler is solid, also by phase
Adjacent two pieces of precast slab units connect even closer.And the material of filler is identical as the material of precast slab unit, filler is dry
It combines together after Gu with precast slab unit, realizes seamless connection, reduce the production of athletic floor later period shelling alice, cracking phenomena

It is made after certain proportion mixing, and the material of filler is identical as the material of precast slab unit, the solid rear and prefabricated board of filler
Unit combines together, and same system has preferable caking property.
The present invention is further arranged to: the elastic granule is one or both of EDPM, TPE particle.
By using above-mentioned technical proposal, EPDM, TPE belong to thermoplastic elastomer (TPE), all with more excellent elasticity with
And elastic recovery properties (creep-resistant property of resistance to flexion).TPE is a kind of high resiliency with rubber, high intensity, and has and can infuse
Mould the environmentally friendly low-carbon composite material of machining feature.It has the performances such as environment-protecting and non-poisonous safety, and has excellent coloring, sense of touch
Softness has weatherability, fatigue resistance, and can be recycled reduces cost.EPDM rubber is asynthetic rubber, main component
For ethylene and propylene, introducing after Third monomer synthesizes is ethylene propylene diene rubber, belongs to saturation high polymer.EPDM ageing-resistant performance
It is superior, weather resistance is good, wear-resisting property is good.Elastic granule adds in filler so that entire bottom have it is appropriate soft
Soft and impact absorbing ability increases the comfort of Athletess, reduces sports fatigue, reduces the probability of movement tumble injury.
The present invention is further arranged to: the filler is prepared via following steps,
Weighing: elastic granule and water soluble acrylic acid adhesive are weighed according to the proportion；
Spice: weighed elastic granule is launched into mixing plant, under conditions of revolving speed 900-1100r/min, while stirring
Water soluble acrylic acid adhesive is added, 10min is stirred, obtains filler after mixing.
By using above-mentioned technical proposal, after being mixed to get filler in mixing plant, filler is filled to circular hole
And in the gap between contiguous prefabricated plate unit, precast slab unit is not only bonded in surface of base after filler is solid, also will
Adjacent two pieces of precast slab units connect even closer.It combines together after filler is solid with precast slab unit, realizes seamless company
It connects, reduces the generation of athletic floor later period shelling alice, cracking phenomena.
The present invention is further arranged to: the precast slab unit includes the following component of content meter by weight percent,
Elastic granule 14-20%

Glutinous agent, then glass fiber reticular cloth is sticked, glass fiber reticular cloth increases the flexibility of product, reduces product and the phenomenon that warpage occurs.Then
Closing middle layer 4 batch is scraped with filler, finally roller coating surface layer 5 on 4, surface layer 5 have certain skid resistance and can provide in middle level
The color sense organ of distinct multiplicity.Roller coating surface layer 5 uses water soluble acrylic acid colour-wash, uses same system, phase with 2 material of bottom
There is preferable caking property with system.And water-borne acrylic coatings have more excellent weather-proof effect, while can be according to design
It is modulated into various demand colors.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
