FIELD: construction; manufacture of porous coatings used on different objects of construction and production of sport and other destination items.
SUBSTANCE: the invention is dealt with methods of manufacture of the porous coatings used on different objects of construction - for building of footways, floors on nursery and running-tracks on sports grounds and athletic fields, and also for manufacture of floor mats of a broad spectrum of destination and rugs for use in means of transport, in rooms and at premises entrances, in swimming and diving pools, etc. For manufacture of a filler for such a coating the conduct crushing of the waste rubber products of bus and rubber industry. In the capacity of the waste products are used aged or unused tire casings, that are crushed into the grits of sizes up to 10 mm. At that as the filler they use from 1 up to 6 mass shares. The binding agent based on polyurethane is taken in amount of 0.8 up to 1.2 mass shares. Coloring agent is taken in amount of 0.03 up to 0.1 mass shares. In the capacity of the coloring agent the dry paints such as iron oxide may be used. Process of stirring is conducted in a screw-type mixer with a reversing drive and a horizontally located screw, the overhead loading of components of the mixture and unloading formulation constituents and its unloading along axis of the axis of the screw at the temperature exceeding 2°С, till production of the homogeneous mass. At that the binding agent is introduced after introduction of the filler and the coloring agent during stirring. Unloading of the produced mass is performed by a screw mixer into a prepared container with consequent stacking on previously prepared surface by an even layer with its final thickness exceeding 3 mm. Then the produced coating is leveled, manually compacted and kept up to its full solidification. The invention makes it possible to simplify the method of coating manufacture at improved quality of items.
EFFECT: the invention ensures simplification of the method of the coating manufacture at improved quality of items.
