METHOD FOR APPLYI NG ELASTOMERI C MATERI AL TO GLASS

Technical Field of the I nvention

The invention subject matter of the application is related to a method developed to apply elastomeric materials to the surfaces of glass household products in different ways to provide decorative and functional properties to the products in the final stage of the production process of the glass household products at room temperature.

Known State of the Art ( Prior Art)

Glass, both as a decorative ornament and as a household good, is applied to a wide range of areas. Especially, glass containers and drinking glasses used for storage and serving of food and drinks as well as glass products used for decorative purposes have become an inseparable part of our lives. Glass products that have a wide range of use are placed on furniture such as tables, coffee tables, and cabinets etc. which are made of different materials. The most significant technical problem when a glass product is placed on a flat, rough or inclined surface is that it slips since it is inherently smooth.

The most efficient way of preventing the glass products from slipping on the surface is to apply non-slip materials on the base having an appropriate shape and amount suitable for different purposes. I n the known state of the art, a large number of materials such as textiles and polymers are mounted as non-slipping support to the glass products during manufacturing. However, among these materials, the most efficient one is elastomeric materials. Elastomeric materials can be used functionally since they provide non-slipping properties and for decorative purposes thanks to different application methods. However, in order to obtain the desired efficiency from elastomeric materials, the method of application to the glass products, presents a great importance.

Objects and Brief Description of the I nvention

Detailed Description of the I nvention

The invention subject matter of the application is a method developed to apply elastomeric materials (4) to the surfaces of glass household products in different ways to bring decorative and functional properties to the products in the final stage of the production process of the glass household products at room temperature and comprises the steps given below:

• Removing the cold coating from the surface of the glass household product, if any,

• Placing the A, B and C (colouring) materials that form the elastomeric material (4) into three different chambers of the dosing unit in liquid form,

· Mixing the A, B and C materials in the dosing system,

• Obtaining the elastomeric material (4) to be applied after mixing,

• Setting the feed rate of the prepared material according to application method,

• I n the case that the glass product is a low depth wide surface container such as a plate, fixing the product on a conveyor performing an indexed movement,

· Application of the elastomeric material (4) on the desired part of the product in desired shape by a robot on which the dosage system is integrated after the product is fixed,

• I f the glass product is a product with a deep and narrow surface such as a glass (3) and if the application will be performed on the external surface of the product, fixing the product on an indexed conveyor such that the product will be rotated on its own axis,

• After fixing, application of the elastomeric material (4) on the desired area in desired shape while the product rotates about its own axis by the robot on which the dosage system is integrated, and

• Oven drying the elastomeric material (4) for curing.

The 2-component elastomeric material (4) used in the method of the invention is obtained from A and B components when in transparent form. A colourless and flexible elastomer is obtained when A and B components come together. A and B materials are held in liquid form in two different chambers in the dosing system and they are mixed at a location close to the injection point by the dosing system . I n order to colour the material, a third C component can be added or the colouring agents can be added into the B component.

The curing time required for the elastomeric material (4) obtained by A, B and C components depending on the application method after being applied on the glass surface depends on the thickness of the elastomeric material (4) and temperature and humidity of the application environment. Curing is completed in 1 -2 hours range depending on these variable conditions. I n order to shorten this time, subjecting the product to heat is the most efficient application method. Curing is accelerated by applying heat while the product is on the conveyor or by putting the product in a separate oven at 80 °C for 10-15 minutes.

Besides, in order to increase the dishwashing machine resistance of the elastomeric material (4) applied on the glass product, a D material can be added into A or B component to enable the elastomeric material (4) to hold on the glass stronger.
