Description

The invention relates to building materials, in particular to compositions of putties intended for leveling concrete and stucco surfaces of walls of buildings and structures Known putty l, including, masd: Lime paste 29-3 Perlite sand 2.5-3.5 Portland Cement Animal glue 2,65-2,86 Water Remaining The closest to the proposed one is putty 2, which includes mas.h: Bone glue 3,5-9,0 Deficit - lime-. containing sugar from the sugar industry10, 0-50.0 Mel groundTOO, household 2.3-8.0 Organic additive - a mixture of drying oil-oxol with a synthetic emulsol 2.0-25.6 Water 45.0-65.0 Known putty they are characterized by insufficient adhesion to the surface of concrete and plaster products and slow drying. The purpose of the invention is to increase the adhesion and shorten the drying time. The goal is to achieve that the putty, including bone glue, lime-containing component, ground chalk, organic water, contains lime as a limestone holding component, and as an organic additive from the process of filling the skin at the next ratio of components, May.%; Bone glue 5.9-8.91 Lime paste 2.9-29, A Chalk, ground 29.6-35.2 Leather processing waste from the process of filling the skin {on a dry basis) 0.35-0.4 Water Elastic Waste, Production from the skin filling process is an aqueous dispersion of a copolymer of methyl methacrylate with chloroprene (copolymer MX-ZO) 0 ,, concentration. The structure of macromolecules of methyl methacrylate copolymer with chloroprene is: I 1 -CH., - C-CH2-sn -ssoosn, i.e. consists of links of chloroprene and methyl methacrylate. Moreover, the methyl methacrylate units in the copolymer macromolecules consist mainly of one monomeric unit, and the chloroprene units, of different number of monomer units. The proposed putty is prepared as follows. A calculated amount of warmed water, bone glue is loaded into the drum of a paddle stirrer, mixed and added to the leather production, limestone dough, finely ground and mixed again for 10-15 minutes. The resulting mixture is passed through krasoterku. Specific compositions of putty and their physico-mechanical properties are given in table. 1 and 2 respectively. The technical and economic effect from the application of the proposed putty is to achieve uninterrupted work in the performance of finishing work, as well as to reduce the cost of putty due to the use of production waste as part of the putty. In addition, recycling leather waste contributes to the preservation of the environment. 1 proposed putty can be used in construction when performing exterior and interior decorating.
