Common court types are acrylic court, EPDM ground, silicon PU court, and the like.
The acrylic acid court is formed by adding a certain proportion of quartz sand and water into high-quality acrylic acid surface layer paint, the paint is a water-based raw material, is bright in color, good in sun resistance, not easy to crack and foam, easy to construct and convenient to maintain, but has a high requirement on a foundation, the foundation is required to be flat and crack-free, water is required to be well prevented, the surface layer thickness is about 2mm after the completion, and the service life of the acrylic acid court is about 4 years. The EPDM floor is composed of a surface layer EPDM colored rubber layer and a black rubber buffer layer, is a non-toxic and tasteless environment-friendly product, can greatly save the foundation cost compared with a PU surface layer, is prepared by mixing EPDM colored rubber particles on the surface with glue, has the thickness of 6mm generally, and can be used as a surface layer of basketball courts and tennis courts. The silicon PU court is a healthy professional elastic synthetic ball court layer material system which accords with the human engineering principle and meets the requirements of sports physical characteristics, is convenient to construct and simple to maintain, can be directly constructed on the basis of asphalt concrete or cement concrete, is simple and convenient to operate, has good energy absorption, shock absorption and wear resistance, absorbs most impact force by a ground system when bearing instant impact, and better protects a sporter from stepping on the ankle by feet.
Silicon PU is an ideal ball surface layer material, and in order to further improve various performances of the silicon PU court, the existing silicon PU court is compounded in a multi-layer mode by adopting different materials. Current silicon PU court material mostly is single component or two ingredient have a large amount of conventional polyurethane materials of packing, and physical properties is poor, and the rebound resilience is low, uses for a long time, takes place hard powdering easily, leads to life low, causes people's joint injury. Because the material contains a large amount of filler, the material is extremely easy to be pulverized after being used outdoors for a long time, so that the service life of the court is short, and about 3 to 5 years, the court material needs to be repaired again or even laid again; in addition, the common court material has low resilience and is easy to cause damage to the bodies and joints of students.
The utility model discloses a no solvent silicon PU court in patent CN201720741757.5, including the metalling, the up end pouring on metalling has concrete layer, the tie coat has been laid to concrete layer's up end, concrete layer passes through tie coat and silicon PU bed course bonding, silicon PU bed course includes prefabricated no solvent silicon PU material to no solvent silicon PU's inside packing has granular gravel, no solvent silicon PU layer has been laid to silicon PU bed course's up end, the insulating layer has been laid to the up end on no solvent silicon PU layer, the insulating layer includes thermal-insulated backing plate, metal coating has been laid to thermal-insulated backing plate's up end, metal coating's surface spraying has metal coating. This no solvent silicon PU court can avoid no solvent silicon PU layer to take place to soften because of the temperature is higher and influence its resilience force, but the physical properties on silicon PU layer can be influenced in the use of graininess gravel, and its shock absorption is poor, and the rebound rate is low, uses for a long time, takes place hard powdering easily, leads to life low.
Disclose a silicon PU type plastic court in patent CN201510282557.3, including basal layer, waterproof layer, silicon PU elastic layer and finish coat protective layer, silicon PU elastic layer comprises screed-coat and enhancement layer, and wherein silicon PU elastic layer adds 10 ~ 20% quartz sand, and the addition of quartz sand has improved the wearability in court, but can influence the physical properties on silicon PU layer, reduces its rebound rate low, and the life in court is shorter.
