Abstract

The invention relates to building materials and is intended for leveling concrete, plastered, wood and metal surfaces. The purpose of the invention is to increase the strength of impact and bending, water resistance and reduce drying time. The putty contains, in wt.%: Lime paste 2-7.5, acidol 10-20, white spirit 12-20, spent plaster forms based on calcium sulfate dihydrate 55-68, household soap 2-10. The drying time of the putty is 2.5-4.0 hours. 2 tab.

Description

The invention relates to building materials, specifically to putties, used to fabricate concrete, plastered, wooden, and metal surfaces intended for painting with glue, water-based and oil paints.

The purpose of the invention is to increase the strength of impact and bending, water resistance and reduce drying time.

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

Spent plaster forms are waste products of ceramic products. For the manufacture of molds, use is made of gtnps, the chemical composition of which determines calcium hemihydrate CaSO 0, containing some calcium anhydrite CaSO and calcium calcium dihydrate CaS04 2H.O,

After a certain service life, the composition of these forms turns into a two-water gypsum with an empirical formula x and becomes unsuitable for the ceramic and porcelain industry.

The proposed putty is prepared as follows.

After heat treatment, pieces of gypsum wastes from the production of ceramic products are crushed on a jaw crusher, then crushed gypsum is passed through small graters to obtain a mixed fraction with sizes ranging from 0.01 to 55 mm.

The organic matter is cut into small pieces, dissolved in warm, water at 70-80 ° C to obtain a 50% solution.

Quicklime is quenched with water, sieved, and, if necessary, evaporated to obtain lime dough with a 50% moisture content.

55-68 kg of prepared gypsum are poured into metal barrels.

2–10 kg of household waste, 12–20 for white spirit, 10–20 kg of xidol and 2–7.5 kg of lime.

Then the surface is leveled, the sludge is left for 15–20 minutes to completely wet the gypsum grains, after which the contents in the barrel are completely transferred to the mortar mixing tank. Then the contents of the mixer in portions are passed into the hopper of the rotary paint grinder for milling. The finished product is placed in the container.

The resulting putty is a homogeneous, non-layering paste-like mass.

The putty mass is applied to the surface to be cleaned with a spatula or a putty unit to fill cracks, cavities and build internal and external concrete, plastered, wooden and metal surfaces of building structures and prepare them for painting to the finish with both.

Putty assigned conditional name Alov-1.
