SU649733A1 - Putty for finishing work - Google Patents

Description

The invention relates to the field of building materials for putties for finishing work and can be used in civil and industrial construction for the preliminary preparation of an oil and glue surface. Known putty on the basis of linseed oxol, syng-ative, animal glue, household soap, chalk and solvent l. A putty is also known, which includes resin (based on the residual lolo solvent fraction), bone glue, household soap, chalk and water. Putty and oil of putties are the use of essential oils made from natural oils as a bonding agent, as well as thorough drying of the base for the putty, which complicates the work, and putty on the basis of ACS resin — the content of a large amount of toxic substances that adversely affect the health of the workers. The closest to the technical essence of the invention is the composition of a lead-free putty, including glue U (based on the sodium salt of karboksimetelcelluloye). Host soap 1st lul and water 31 An otherwise well-known composition has a neo-sufficient strength (2 kg / cm), honey, leihyu dries out when applying olo more than 0, S mm (a layer of 0.5 mm applied putty dries 4 hours). The chain of the invention is to increase the strength, reduce the drying time and the expansion of the range. The goal is achieved by the fact that the putty, including sodium carboxymethyl cellulose, household soap, chalk and water, additionally contains a 33% aqueous solution of saponified tall oil pitch in the following ratio, wt.% 1 33% aqueous solution of saponified tall oil pitch . 5.5-7.0 Carboxymethylcellulose Sodium Salt 1.0-1.4 ml, fo fool, 25-0.35, Mel60.0-70.0, WaterOtheral, Washed tall oil pitch is a viscous mass obtained from tall oil saponification 10% -HiA4 grow in orom SoCoz. %: Composition of tall nstcaf Smooth acid ika12-15 nifol) Neutral substances (stearin) 30-40 Fatty acids 15-21.
