Abstract

The invention relates to industrial household chemicals, in particular to compositions for cleaning metal surfaces. The purpose of the invention is to increase the cleansing effect and dirt of the repellent effect of the means for cleaning letter type fonts. The tool contains, wt%: butyl acetate 9.0-10.0; caprolactam 0.1-0.7; acid ester alkenyl succinic acid 0.01-0.03; white spirit 5-32; and gasoline-solvent with a boiling point of 80-120 ° C to 100. The introduction of caprolactam and alkenyl succinic acid ester contributes to an increase in the cleansing effect and effect of the repelling effect. The cleaning ability of the product is 80-90% by weight when removing contaminants from a typewriter. The cleaning time of one typewriter is no more than 1 min. The contamination dissolves and is removed in 3-4 seconds. The tool has a zeottic effect, there is no corrosive effect. 2 tab. with f (ls

Description

This invention relates to the household chemical industry, in particular, compositions for cleaning metallic surfaces.

The purpose of the invention is to increase the cleansing effect and the repellent effect.

The formulations of the proposed tools are presented in table 1.

To obtain the agent, equipped with a stirrer (60 rpm), load the calculated amount of butylacetate, add the acid ester of alkenyl succinic acid and caprolacta. After aqueous dissolution of the acidic acid, alkenyl succinic acid and caprolactam are added white spirit and gasoline Galosh

The process is carried out at room temperature.

Table 2 shows the physico-mechanical properties of the proposed and known means.

Quality indicators are determined by known methods.

Comparative tests were carried out with a known agent of the following composition, wt.%:

Oil solvent 60

Oleic acid 1, 5

Water36,5

Ammonia 25%

water0,5

Peitol1,5

2-3 ml are sufficient for cleaning the font of one typewriter. The tampon is moistened with this amount of funds and all typewriter type letters are cleaned. One swab is enough to clean one typewriter.

The time of complete cleaning of one typewriter is no more than 1 min. The contamination dissolves and is removed in 3-4 seconds,

As follows from the data of table 2,

The proposed remedy has at the same time high cleaning ability and a repellent effect. Its advantage is a short evaporation time, as well as use in small quantities, which reduces the fire hazard of the cleaning process,

Formula of invention.

A tool for cleaning typewriter typefaces containing white spirit, gasoline-solvent with a boiling point of 80-120 0, butyl acetate and a surfactant, characterized in that in order to increase the cleaning effect and the repellent effect, the agent contains an acid ester of alkenyl succinic acid as a surfactant and additionally contains caprolactam at the following ratio of components, wt.%:
