Definitions
- the invention relates to a substantially liquid aqueous composition, based on rare earth oxide, for the maintenance of the polished appearance of smooth surfaces. 'objects to present such an aspect.
- the invention relates, more particularly but not exclusively, to the maintenance of faces of glazing of the so-called semi-reflecting type, that is to say of glazing of which one of the faces is made partially reflective to light rays by depositing a thin layer of metal compounds, such as metal oxides.
- the thickness of the aforementioned layer is generally between zero point three and one point two micrometers (0.3 and 1.2 ⁇ m).
- composition of the invention can also be applied to the faces of objects of material of a nature as diverse as polyvinyl chloride, stainless steel, lacquered paint, copper, marble.
- glazing of the semi-reflecting type has the distinction of being sensitive to certain atmospheric agents which significantly alter the polish of their partially reflecting face.
- composition is criticized for being particularly subject to the phenomenon of syneresis and, moreover, for sensitizing semi-reflecting glazing to the action of altering atmospheric agents.
- polishing compositions are known such as that described in the patent application (GB-A-2.01.1939).
- Such polishing compositions contain cerium oxide particles whose diameter is between one and fifty microns, which gives them a high abrasive power and prohibits their use for the maintenance of glazing of the aforementioned type.
- the abrasive composition described in the patent application would not be suitable for the maintenance of glazing of the aforementioned type because it contains in particular abrasive particles whose diameter is between thirty and five hundred microns .
- a first result which the invention aims to obtain is a composition for the maintenance of the polished appearance of smooth faces of objects having to have such an appearance, which composition has no destructive effect on a possible coating of metal oxide that can include the face thus treated.
- a second result which the invention aims to obtain is a composition for maintaining the polished appearance of semi-reflective glazing which has a protective effect on said surface, that is to say which hinders its deterioration by atmospheric agents .
- a third result which the invention aims to obtain is a composition of the aforementioned type which is stable over time, that is to say which, in particular, is not subject to syneresis.
- the subject of the invention is a composition of the aforementioned type, particularly characterized in that:
- the rare earth oxide present in the composition is there in the form of particles whose average diameter is less than one two micrometers (2 ⁇ m) and,
- the aqueous solvent comprises a polysiloxane oil and a degreasing and diluting agent for the polysiloxane oil.
- the composition is aqueous, substantially liquid, based on rare earth oxide and is used for the maintenance of the polished appearance of smooth faces of objects having to have such an appearance.
- the composition is advantageously made from cerium oxide, kept in suspension in a substantially liquid solvent containing water.
- the rare earth oxide present in the composition is found there in the form of particles whose average diameter is less than one two micrometers (2 ⁇ m).
- the composition contains a surfactant.
- the average diameter of the rare earth oxide particles is between half a micrometer (0.5 ⁇ m) and one and a half micrometers (1.5 ⁇ m).
- Rare earth oxide consists of cerium oxide and, remarkably, in a selection of at least eighty percent (80%) pure cerium oxide. The choice of the purity index of the cerium oxide is decisive for the chemical stability of the maintenance composition.
- the liquid solvent comprises:
- polysiloxane oil is, on the one hand, to coat the particles of rare earth oxide in order to allow them to remain in suspension in water and, on the other hand, to generate the constitution of a protective film on each side treated with the composition.
- the polysiloxane oil is a polymethylsiloxane oil.
- polysiloxane oil has, at a temperature of twenty five degrees centigrade
- the degreasing and diluting agent of polysiloxane oil is an agent made up of esters, hydrocarbons and surfactants.
- the surfactant is of the quaternary ammonium type and comprises a carbonate sequestering agent.
- the degreasing agent is an aliphatic hydrocarbon.
- the degreasing agent is an aromatic hydrocarbon.
- the proportions of the various remarkable constituents of the composition are, as a percentage of the total weight of the composition containing water, of:
- the proportions of the various remarkable constituents of the composition are, as a percentage of the total weight of the composition containing the water of:
- the composition contains a thickening agent in a proportion varying between zero point one and twenty five percent (0.1 and 25%) by weight of the composition containing water and, preferably, in a proportion of zero point four percent (0.4%).
- the thickening agent is of the nonionic heteropolysaccharide type, such as xanthan gum.
- composition of the invention contains phosphoric acid or phosphomolybdic acid.
- composition of the invention is extremely simple since it consists in:
- composition onto a cotton ball or felt pad, applying the impregnated side of the pad to the side to be treated, rubbing and allowing the composition to dry on said side, and
- composition of the invention therefore requires no preparation of the face to be treated, nor any rinsing of the treated face.
