The invention relates to building materials and can be used in arranging coatings for sports grounds, in particular tennis courts.

The aim of the invention is to increase the durability of the coating, at a separation and at a negative temperature.

The composition is prepared as follows. .

The rubber, oligoether acrylate, vulcanizing agent, iron oxide, block copolymer and water roll at 80–90 ° C for 3–6 min, then crumb rubber is added and rolled for another 3–5 min. Then the mixture is placed in the mold and vulcanized in a press at 150-180 ° C for 20-45 minutes. After that, the product cooled down before and left for 24 hours.

In the proposed composition, rubbers are used: butadiene, styrene butadiene, isoprene, butyl rubber, etc., oligoesters - oligoether acrylate, TGM-3., MGF-9, or oligocarbonate methacrylate, as a vulcanizing agent, peroxymon or an oroxy- etheroxy. magnesium in the ratio 2: f,

Rubber crushing is used for resilient grinding.

Examples of specific composition and properties are given in table. 1 and 2,

As can be seen from the above data, the coating made from the proposed composition has high strength at tear and at negative temperature.,

Invention Formula

The composition for covering sports fields, including rubber, rubber crumb, oligoacrylate and a vulcanizing agent, has been applied so that, in order to increase the strength of the coating during tear and negative temperature, it additionally contains iron oxide, nitrogen-containing tetrafunctional block copolymer of ethylene oxides and propylene and water in the following ratio of components, wt.h .:
