Definitions
- the present invention relates to a removable multi-layer system consisting of a formulation based on acrylic resins in a water dispersion and selected fillers, a fibre-reinforced PVC mat and a removable adhesive, which said system can be used to make surfaces with high wear resistance for professional tennis court use and indoor multi-sport areas.
- Sports surfaces are the crucial construction component that determine the quality of a tennis court, and significantly influence the technical characteristics of the game played on it.
- the physical factors that determine the characteristics of a surface are friction, elasticity, damping and bounce.
- Elasticity is a very important characteristic, because it determines the ability of the surface to dampen the impact forces of the foot during play.
- An optimum elasticity value aids speed, reduces muscle fatigue, and limits the possibility of trauma to the joint ligaments.
- a fundamental characteristic of the surface is its damping capacity, namely its ability to return to the limbs a quantity of energy less than the impact energy.
- Bounce height is determined by elasticity, damping and friction.
- stabilised soil is category 1, while synthetic surfaces, as already stated, can have a speed ranging from 1 to 5.
- Synthetic clay and synthetic grass are much less commonly used for professional tennis, but are employed to quite a large extent for amateur use.
- the choice of surface must be based on a plurality of factors: -
- the prevalent use of the court professional tennis, training, amateur or recreational tennis, or all-purpose use; if mainly professional or training use is envisaged, it can be useful to choose synthetic courts with an average speed, which are the most common type of surface used on the professional circuit; however, if exclusively amateur use is envisaged, red clay is normally the best solution; while if the court is to be used for a number of disciplines, a synthetic grass solution can be considered, so that five-a-side football matches can also be played, for example.
- the courts can then be improved at a later stage by laying other layers of better-quality, technically good resin that build on the initial investment and optimise the forms of use and the profit and loss account.
- the system object of the invention consists of the following components:
- Removable adhesive mat/base containing a water dispersion of vinyl acrylic resins, a water dispersion of carboxylated acrylic resins, a tackifier resin based on rosin, and inorganic fillers.
- suitable fillers of the formulation include talc, quartz, calcium carbonate and silicates, preferably quartz and/or talc.
- Dry residue 60-75%, preferably 68-72%.
- Brookfield viscosity (rotor - 6-10 rpm): 60,000-75,000 mPa.s preferably 68,000-72,000 mPa.s.
- - talc 5-10%, preferably 8-9%.
- the mean size of the resin particles is about 0.1 microns.
- the speed characteristics of the surface can be modulated by varying the type of fillers in the formulation.
- a quartz with the following characteristics will be used:
- Thickness 1.5 mm (+/- 0.2 mm)
- Hardness 70 Shore A (UNI EN ISO 717-2).
- the removable adhesive mat/base containing an aqueous dispersion of vinyl acrylic resins, an aqueous dispersion of carboxylated acrylic resins, a tackifier resin based on rosin, and inorganic fillers, has the following characteristics:
- Consistency liquid; Dry residue: 30-56%, preferably 40-49%;
- Brookfield viscosity (rotor 4-20 rpm): 500-2000 mPa.s, preferably 1000-1500 mPa.s.;
- - inorganic fillers preferably calcium carbonate: 8-16%, preferably 12-14%.
- the carboxylated acrylic resin also presents the following characteristics: ⁇ Mean particle size: 0.2 microns;
- Vistex (mean viscosimetric molecular weight): from 1.07 to 1.10 dl/g.
- the system object of the invention improves the performance of the different playing surfaces and guarantees that the court will have an excellent level of softness, at the same time maintaining the speed and precision typical of a synthetic or cement surface.
- the system meets the needs associated with the safety of the players and the techniques of the game, with significant financial advantages associated with rapid maintenance, and renovation if necessary.
- Said system therefore allows the construction of surfaces with a high degree of comfort of play and excellent technical performance such as the bounce of the ball, a rapid, safe change of direction when running, and an excellent ratio between balance and slipping by the user.
- the system of the invention can be applied to already painted old indoor flooring or to new cement or asphalt flooring which needs to be coated. It can be made in different colours, guarantees excellent scratch resistance and resistance to all weather conditions, and ensures that the backing will receive long-lasting protection.
- the system of the invention allows sports surfaces to be installed even for short events or exhibitions, as they are easily removed after the end of the event.
- Finishing application of resin-filler formulation in 3-4 coats, 6-12 hours apart, preferably after 12 hours.
