Description

BACKGROUND OF THE INVENTION The present invention relates to a self-polishing floor conditioner which, in addition to its cleaning effect, forms a thin, durable protective layer on the floor surface and imparts a pleasant light to the surface. It also facilitates further cleaning.

It is known that in the past, parquet floors and floors were covered with beeswax and polished. Recently, this solution has been replaced by varnishing. Lacquered parquet, but mainly plastic, for example. For cleaning and care of PVC and stone, marble surfaces, instead of or in addition to purely aqueous wiping, it is also advisable to use aqueous formulations that form a thin protective layer on the surface, give back light to the worn surface and increase durability.

The hardness, abrasion resistance, water resistance of floor care products containing predominantly wax emulsion is relatively poor and generally provide adequate light only by polishing and brushing. Hardness and wear resistance can be improved by adding an aqueous polymer dispersion. Due to their limited adhesion (adhesion) they are not suitable for grinding stone pavements.

Die Chem.-Techn. Industrie 61. Oct. 1965; 8. Pages 21/1 767-769 discloses self-shining emulsions containing styrene, synthetic resin and shellac. The polystyrene emulsions are modified with shellac or copolymerized with synthetic resins or styrene acrylates.

The US. According to U.S. Patent 2,596,960, emulsion resin employs an aqueous emulsion of polyvinyl acetate, a plasticizer dibutyl phthalate, an emulsion of a mixture of kamauba and montan wax, a nonionic surfactant, a shellac dispersion, and triethanolamine.

The self-polishing floor conditioner of the present invention has improved surface wetting properties and hardness of the resulting coating as compared to prior art formulations, and has improved its spreadability, gloss and adhesion.

For cleaning and care of lacquered parquet surfaces, it is advisable to use these aqueous compositions instead of or in combination with a wet wipe, since they form a thin layer on the surface, restoring the gloss of the worn surface and thus increasing the durability of the lacquer.

In our studies, it has been found to be desirable to use an aqueous polymer dispersion having a particle size of up to 0.1 mm and a relatively high glass transition temperature (Tg) of at least 40 ° C and polyamide maleic acid to facilitate film forming processes at room temperature. contains its semester. The semi-ester containing hydroxyl and carboxyl groups improves the wettability and film-forming properties of the composition.

The self-polishing floor cleaner of the present invention comprises 2030 parts by weight of a 30-50% aqueous acrylate copolymer resin solution, 45-65 parts by weight of deionized water,

3.5-4.5 parts by weight of an aqueous ammonia solution of 10-20% by weight of the reaction product of rosin and maleic anhydride, 6.5-8.0 parts by weight of a polyethylene wax emulsion, 0.55 parts by weight of sorbitol and / or a 1: 1 mixture of sorbitol and ethylene glycol in maleic anhydride. 10-20% aqueous ammonia in its semester;

Contains 3.5 to 4.8 parts by weight of plasticizer and 1.0 to 3.0 parts by weight of surfactant.

The reaction product of sorbitol and maleic anhydride in the composition of the present invention was prepared according to British Patent No. 928,182.

The rosin maleinate adduct is formed by the addition of abietic acid and other resin acids and maleic anhydride. The resulting resin is hard; powdered alkaline e.g. easily soluble in water, which is alkaline with ammonia or amines.

The self-polishing floor cleaner of the present invention is illustrated by the following examples.

To improve the surface light, the hard resin solution and the reaction product of sorbitol + maleic anhydride are added to the composition. At the same time, there is a measurable increase in adhesion and gloss on the lacquered surface.

A small amount of surfactant is used to further improve spread. A 15% solution of the surfactant is prepared for easier and more accurate dosing.

Both the reaction product of rosin and maleic anhydride as well as the semisester of sorbitol with maleic anhydride are dissolved in ammonia water, and the components of the self-polishing floor cleaner of the present invention are weighed in the order shown in the example and stirred in an autoclave for 60 minutes.
