METHOD OF PRODUCTION OF HIGHLY DISPERSED MATERIAL FOR MANUFACTURE OF DAMPPROOF, ANTINOISE AND SPORT SURFACES Russian patent published in 2008 - IPC B29B13/10 B29B17/00 C08J3/20 C08L17/00 

FIELD: technological processes.

SUBSTANCE: method includes processing of rubber crumb with thermoplastics in device of rotor type for high temperature shear grinding during heating by means of simultaneous exposure of processed material to pressure and shear stress. At that processing is carried out in two stages. At the first stage rubber crumb or mixture of rubber crumb and one thermoplastic with ratio of rubber crumb: thermoplastic or mixture of thermoplastics, equal to, weight % (99.5-90.0):(0.5-10.0), are processed under conditions that provide high temperature shear grinding of rubber crumb. At the second stage processing of product produced at the first stage is carried out in the presence of thermoplastic or mixture of thermoplastics with the following ratio - product produced at the first stage: thermoplastic or mixture of thermoplastics, equal to, weight % (2-90):(98-10). At that processing is carried out under conditions that provide high temperature shear grinding of thermoplastic or mixture of thermoplastics.

EFFECT: increase of extent of mixture uniformity and high physico-mechanical and other operational characteristics of coating.
