METHOD OF PRODUCING INERT MATERIAL

摘要

FIELD: chemistry.SUBSTANCE: invention relates to production of polymer composite materials. Non-plasticised cellulose fibres are used as the reinforcement component and polyvinyl acetate is used as the binding component. After dilution of the suspension with water to working concentration of 0.9-1.1% at temperature higher than 25°C, the polyvinyl acetate is deposited on the cellulose fibres by adding components of aqueous aluminium sulphate solution at 70-80°C to the aqueous dispersion. The amount of aluminium sulphate is 2.0-2.5 pts.wt per 1 pts.wt polyvinyl acetate. The mixture is stirred for 20-30 minutes.EFFECT: method of producing inert material, which includes preparing an aqueous suspension of components, forming a matrix from the obtained mixture and removing water.1 tbl
