HEAR PUTTY AND METHOD OF PREPARING THEREOF Russian patent published in 2001 - IPC

FIELD: building materials industry, more particularly leveling and correction o defects of surfaces. SUBSTANCE: 0.24-0.3 wt.pt of plasticizer is placed into water and the whole is stirred. 50-70 wt parts of clay, 1-5 wt. pts of clay, 1-11 wt parts of hydroxyethyl cellulose (0.1-0.5 wt.pt) and hydroxypropylmethyl cellulose (0.1-0.5 wt.pt) and 1.5-10 wt.pt of latex or aqueous dispersion of polymers are added successively to solution. After stirring, water is added to viscosity of 38.000-65.000 mPa.s. Vacuum treatment is thereafter carried out to 0.05-0.2 atm for 10-30 min. Hard putty is applied onto surface of any material in thin layer to prepare elastic readily grindable coating which dries out within short period of time. EFFECT: improved properties of the hard putty. 5 cl, 2 ex
