Description

The invention relates to putty formulations and can be used for leveling concrete and plaster surfaces.

The purpose of the invention is to increase the elasticity, adhesive and cohesion strength.

The compositions of the putty and their physico-mechanical parameters are given in table. 1 and 2.

The bottoms residue from acetylacetone vacuum distillation is a waste product of acetylacetone, which is used in chemical syntheses of drugs. VAT residue is formed at the first stage of production - regeneration of acetate-acetone. Properties of the bottom residue: specific gravity of 1.2 g / l; ash content 7 g / l. Composition of VAT residue, g / l: resin-forming substances 675; 67 acetone-acetone. Flash point

residue 114 ° C, ignition temperature 117 ° C. Elemental composition, wt.%: Hydrogen 10.3; oxygen 5.15; carbon 31.9; nitrogen traces, sulfur is absent.

The putty is prepared as follows.

Into the mixer, water is subsequently introduced, household soap, after mixing, the bottom residue from the vacuum distillation of acetylacetone is added and mixed again to obtain a homogeneous mass. Ground chalk is then added to the mixture, ground on a spray meter.

. The increase in adhesion and cohesive strength is achieved by chemical interaction of chalk with acetylacetone to form calcium acetyl acetonate, which contributes to hardening the structure of putty. In addition, when applying the specified putty on the cement substrate pro (/

Acetylacetone is chemically reacted with lime on the substrate, resulting in the formation of calcium acetylacetonate, which contributes to an increase in the adhesive strength of the putty. The acetone contained in the bottoms residue accelerates the precipitation of silica gel during the solidification of liquid glass, which accelerates the curing process of putty.
