Hard surface cleaning composition containing waterborne polyurethane dispersion and preparation method thereof

Abstract

The invention provides a hard surface cleaning composition containing a waterborne polyurethane dispersion and a preparation method. The hard surface cleaning composition comprises the following components: (a) 1-30 weight parts of a waterborne polyurethane dispersion; (b) 0.1-15 weight parts of a surfactant; (c) 0-3 weight parts of a chelating agent; (d) 0-30 weight parts of a solvent; and (e) anaqueous carrier. The hard surface cleaning agent composition provided by the invention has excellent decontamination, anti-fogging, anti-scaling, dapple reduction and other properties, cationic groups are introduced into the polyurethane dispersion, after use, the effects of bacteriostasis, static electricity resistance and the like can be achieved, meanwhile, the castor oil modified polyurethanecan also form a layer of durable transparent protective film with toughness and glossiness on the hard surface, the film can be easily peeled off from the surface and take off dirt staying on the film in a next cleaning process, the surface material is not damaged, a new protective film can be formed again after the composition is used for cleaning, and the cleaned surface is further protected.

Description

technical field [0001] The invention belongs to the technical field of civil or industrial cleaning, in particular to a hard surface cleaning composition containing aqueous polyurethane dispersion and a preparation method. Background technique [0002] In recent years, with the development of society, people's living habits have gradually changed, surface materials have been continuously updated, and people's awareness of environmental protection has gradually increased. The development of hard surface cleaners for civil and industrial use has become more and more rapid. In general, hard surface cleaners should remove surface dirt without damaging the surface to be cleaned, leaving no streaking residue, etc. on the surface. The ideal situation is: the surface does not need to be rinsed, the cleaning agent will not leave streaks, stains or traces, has a certain sterilization and antibacterial effect on the cleaned surface, and is harmless to the surface, users and the environ...

Problems solved by technology

However, due to the low amount of polymer added in this patent, the thickness of the formed film is low, it does not have peelability, it cannot improve the secondary cleaning ability, and the polymer has no surface activity, so it cannot be synergistically decontaminated

Chinese literature patent CN201380056767.X also relates to a hard surface cleaning composition, but this composition mainly emphasizes that after adding the polyurethane / polyacryl hybrid dispersion, it provides gloss and water resistance to the hard surface, but the cleaning in the comparison document After the agent is used, the gloss is average, and the formed polymer film is relatively thin, which has no obvious protective effect on the surface, and is not easy to peel off. It is not easy to take the dirt on the surface of the polymer film away from the surface when cleaning next time.
