Description

Technical field

The invention relates to glass articles, in particular hollow articles, on which there is a layer with good abrasion resistance which has a good appearance (is homogeneous, translucent and invisible) and allows adaptation of the glued parts.

BACKGROUND OF THE INVENTION

Glass articles, especially hollow articles, may collide with each other when used, filled, packaged or washed prior to use, which may cause abrasion, especially scratches, thereby reducing their mechanical strength.

It has already been described that the surface of glass articles can be treated to improve their abrasion resistance, regardless of whether the articles are dry or wet, for example when they are washed.

Thus, U.S. Pat. No. 3,438,801 describes the treatment of glass bottles with the aim of improving their dry abrasion resistance by using an aqueous solution of diaminosilane, i.e. 3- (2-aminoethyl) -aminopropyltrimethoxysilane, In the second step at 140 ° C an aqueous solution of polyethylene in combination with a potassium salt of oleic acid is used.

Such glass bottles are generally intended to be sealed and consequently the abrasion-resistant layer applied to the glass surface also allows good adhesion of the label using conventional adhesives such as casein and dextrin. To achieve such good adhesion as well as corresponding good abrasion resistance, U.S. Pat. No. 3,873,352 describes the treatment of a glass surface with an aqueous composition comprising a polyethyleneiminopropyltrimethoxysilane having a molecular weight of about 1400 (or a mixture of silane with diaminosilane, DAMO) and polyethylene in combination with potassium.

However, it has been noted that such layers are associated with a cloudy appearance and thus render these glass items unusable, as well as the abrasion resistance of

However, it has been noted that such layers are associated with a cloudy appearance and thus render these glass articles unusable, as well as that the abrasion resistance of these articles in moisture is insufficient. In addition, some of these layers do not allow the label to adhere well.

Attempts have been made to form coatings on the glass surface that have a good appearance and on which labels would adhere well to achieve such good abrasion resistance in both dry and wet conditions.

There has also been a search for a simple manufacturing method that can be used in industry, both on the production lines of such glass articles, as well as for their recycling, for example refilling them.

In particular, the cover layer dry matter and monoaminosilánu monoaminosiiánov applied to the surface of glass being between 10 ^-4 mg / cm ² to 5.10 ^"2 mg / cm ^2, preferably from 6:10" ³ mg / cm ² and 10.5 ^"2 mg / cm ^2, and dry matter and the dry matter applied to the surface skia moving amount between about 5.1 * ⁴ mg / cm ² to 5.10 ^"2 mg / cm ^2, preferably between 2.10 ^-3 mg / cm ² to about 10 ² mg / ^cm2.

By the surface used is meant the surface of the glass article which is usually exposed to the risk of abrasion and which must therefore be protected by a covering layer.

In the aforementioned general formulas of the monoaminosilanes, R ¹ and R ² may have the same or different meanings and preferably represent hydrogen or a methyl group, R ³ represents, for example, a propylene, butylene, isopropylene, preferably propylene or oxyethylene, a polyoxyalkylene group containing a number of different oxyalkylene units, R ⁴ preferably represents a methyl or ethyl group, each of R ⁵ and R ⁶ having the same or different meanings preferably being a methyl or ethyl group, or else a group of the formula -O- (C 11 H 2 nO) b R ⁴ ; m and n are preferably 2 or 3, and b and n are preferably zero or 1, R ⁷ is preferably hydrogen or a methyl group, and X is a chloride, bromide, sulfate or methyl sulfate anion.

Monoamino silanes which are particularly useful in the present invention include, for example, 3-aminopropyltrimethoxysilane, 3-aminopropyltriethoxysilane,

4-aminobutyltrimethoxysilane, N-methyl-3-aminopropyltrimethoxysilane and 3-aminopropyltris (2-methoxyethoxyethoxy) silane.

Adhesives useful in the process of the present invention are preferably: oleic acid, sodium or ammonium salt of stearic acid, any of the long-chain alkylaminoacetates (carbon atoms greater than or equal to 8) such as tallow or coconut oil, a polyolefin or a mixture thereof products. However, an oxidized or partially oxidized polyolefin is particularly suitable.

The oxidized or partially oxidized polyolefin may preferably be polyethylene, polypropylene or polyisobutylene or most preferably polyethylene.

Particularly suitable are oxidized or partially oxidized polyethylene having a relatively low molecular weight, for example in the range of 1000 to 10,000.

The method of manufacturing these glass articles depends on applying the silane or silanes and the lubricant or lubricants to the heat-treated glass surface simultaneously or sequentially.

The heat treatment is preferably carried out at a temperature in the range of 60 ° C to 160 ° C, most preferably in the range of 80 ° C to 150 ° C. At temperatures above 180 ° C, the coatings do not allow good label adhesion and the optical density is insufficient.

In particular, to achieve the cover layers with the properties as described below, it is sufficient to heat the glass surface to a temperature in the range indicated above, i. in the range of 60 'C to 160' C, preferably in the range of 80 'C to 150' C before or after the application of the silane or silanes and the lubricant or lubricants. The surface temperature can be controlled and controlled by any suitable means, for example using an infrared pyrometer.

The process of applying the cover layers to the glass surface as described above can be carried out in one step in that the silane (silane) and the adhesive (s) are in the same composition. It is also possible to apply the silane (s) in the first stage and then the adhesive (s) in the second stage.

The cover layer formed on the glass surface is achieved, for example, by applying an aqueous monoaminosilane or monoaminosilane composition and a lubricant or lubricants.

In particular, if the deposition is carried out in a single step or in two steps, the compositions used for such deposition may comprise from 0.005% to 2% by weight, preferably from 0.01% to 1.5% by weight. % of monoaminosilane or monoaminosilanes; and from 0.10% to 2% by weight, preferably from 0.15% to 1.5% by weight. glue (s).

As mentioned above, the adhesive is preferably an oxidized or partially oxidized polyolefin, most preferably in the form of a nonionic or ionic aqueous emulsion.

The coating on the glass surface can be carried out by any suitable method, for example with a brush or by spraying, especially when treating the glass surface at a higher temperature or by spraying or immersion in an aqueous solution if the treated glass surface is at a low temperature.

The composition may be sprayed onto the glass surface by any suitable method, but in particular by using a pneumatic spray device. It is also possible to use an ultrasonic spray device.

If the application is by brush, a brush impregnated with the composition or else with a precipitate obtained by precipitating the components in an acidic medium is used.

According to one embodiment of the present invention, the aqueous composition of the monoaminosilane or monoaminosilanes and the adhesive (s) is applied in one step. Such a composition may be applied directly to the glass surface at a temperature in the range as above, i.e. in the range of from 60 ° C to 160 ° C, preferably in the range of 80 ° C to 150 ° C. The heat treatment then takes place simultaneously.

However, it is also possible to apply the monoaminosilane (s) and the adhesive (s) to the glass surface at a temperature below 60 ° C, for example at room temperature or even lower. This is particularly the case when such articles, especially bottles, are intended for recycling. After being applied to the glass surface, the components are heat treated by heating at least the glass surface to a temperature in the range as above.

Another method of carrying out the present invention consists in applying to the glass surface in the first step an aqueous solution of monoaminosilane or monoaminosilanes, and in the second step an aqueous adhesive or adhesives composition. The aqueous silane or silane solution may be applied directly to the glass surface at a temperature in the range of 60 ° C to 160 ° C and the aqueous lubricant composition is then applied at a temperature within the same range. Between two applications, it may be necessary to heat the glass surface to be treated, taking into account that at least the glass surface has the temperature required to apply the aqueous adhesive composition (s), i.e. to a temperature in the above range.

Another method is based on applying an aqueous solution of silane or silanes at a temperature below 60 ° C, for example at room temperature, followed by heating the glass surface to at least a temperature of between 60 ° C to 160 ° C, preferably in the range 80 ° C to 150 ° C. wherein an aqueous adhesive / adhesive composition is then applied. In carrying out this second deposition process, according to the invention, at least the glass surface must be heated - if necessary - before or after the deposition of the aqueous adhesive / adhesive composition.

According to yet another process of the present invention, the aqueous silane (silane) solution and the aqueous adhesive (s) suspension are subsequently applied at a temperature below 60 ° C and then the coating is heat treated and treated by heating the glass surface to at least 60 ° C to 160 ° C.

The heat treatment can be carried out by any suitable device, particularly at the outlet of the heating furnace, or during the production of glass articles. It is also possible to do this in the heating space by blowing hot air under infrared heating or by microwave.

If the deposition of the components, ie silane (silanes) and lubricant (s) takes place on the glass surface at a temperature higher than 60 ° C or preferably above 80 ° C, no further temperature increase during the heat treatment is necessary; in this case the application and the heat treatment take place simultaneously.

The application of the components to the surface of the glass articles at low temperature can often be advantageous in particular with regard to the possible recycling of the articles intended for further use. Such deposition can be carried out, for example, after washing these articles.

In the examples that follow and explain the process without limiting it in any way, glass objects (bottles) are placed in a rotary machine at 75 to 130 rpm and the deposit is sprayed.

The treated and treated bottles are then tested to determine the dry and wet abrasion resistance, the appearance of the deposited layer and the adhesion of the label.

DETAILED DESCRIPTION OF THE INVENTION

The following tests were performed;

1. Abrasion resistance

The test is based on placing two bottles on the same treatment horizontally, one on top of the other with the lines forming an angle of 30 ° and pushing one another against each other, allowing one to slide second. If the pressure increases, the abrasion occurs when the force used is to be increased so that the two bottles slide on top of each other. The force exerted is limited to 400 N, since a higher force would result in the breakage of one bottle or both.

The acceptable value of the abrasion resistance depends on the requirements associated with the use of the glass article. The minimum value is considered to be 200 N dry and 100 N wet. In general, good abrasion resistance values are obtained at values higher than 300 N dry and higher than 200 N wet.

For information only, in the case of an untreated bottle, the chafing starts to appear at about 20 N.

2. Adhesion of label

A paper label is used using a conventional adhesive such as a casein-based aqueous adhesive. Allow to dry for 3 to 4 hours at ambient temperature or 20 minutes at 60 ° C.

To determine the adhesion of the label, an attempt is made to tear it off, and the surface of the glass container is checked.

If it remains from the label

100% excellent adhesion% acceptable adhesion below 80% unacceptable adhesion

3. Layer appearance

The layer must be homogeneous, transparent and invisible. Testing shall be performed visually:

- layer not visible, good appearance

- the layer as a whole is not visible, but a visible value of 0 is small dots, acceptable appearance

- the layer is visible, the appearance unacceptable

- appearance is cloudy, unacceptable value 1 value 2 value 3

The following silanes were used in the following cases: 3-aminopropyltrimethoxysilane 3-aminopropyltriethoxysilane [3- (2-aminoethyl) aminopropyl] -trimethoxysilane or N-methyl-3-aminopropyltrimethoxysilane
