Description

(54) PUTTY

The invention relates to construction materials, and in particular to the compositions of putties used in the repair and construction and finishing works of residential, public and industrial buildings. Known putty, including, wt.%: Distillation residues of the products of the pyrolysis of methyl ester 1,5-3; aqueous solution of bone glue 1-2; filler 60-75; an aqueous solution of household soap 0.5-0.7 1. The closest to the proposed technical essence and the achieved result is a putty, including, weight. including: distillation residues from the rectification of crude benzene 2-4.0; 10% aqueous solution of bone glue 18-20; 10% aqueous solution of laboratory, 6.0-6.5; ground chalk 60-65; water up to working density 2. The disadvantages of known putties include loss of adhesion properties when applied to surfaces without careful preparation, greater shrinkage and cracking during drying and abrasion, as well as increased drying time after application to the surface to be finished. The purpose of the invention is to increase adhesion, reduce shrinkage, abrasion, and also reduce drying time. This goal is achieved in that the putty, including organic binder, ground chalk, bone glue and water, contains as an organic binder waste production of butyl acetate at the following ratio of components, wt.%: Waste production of butyl acetate 8-10 Ground chalk60-65 Bone adhesive 18 -20 Water Else Butyl acetate waste contains in its composition, wt.%: Butyl alcohol 5-10; butyl acetate 4-8; isoamylacetate 0.5-2; butylpropionate 1-5; butyl isobutyrate 1-6; butyl butyrate 0.8–7.0; butyl isovaleanate 0.6-1.4; resinous substance else. Specific formulations of the proposed tschakpevki are given in table. one.

Comparative physicomechanical indicators of pradlagvema and known putties are given in table. 2

table 2

The proposed filler has a light yellow color, the creamy consistency is maintained by adding water, the smell

weak, volatilized 2-3 hours after drying, the putty is non-toxic.

The proposed putty applied to the surfaces to be treated, has a high adhesion to concrete, brick, plaster and wooden surfaces, does not give shrinkage and delaminations during drying. In addition, the advantage of the proposed putty, in comparison with the known, is the possibility of applying it on wet surfaces, while it dries with the treated surface.
