The paint is produced by a method including providing a film-forming binder component; providing a color-producing component; mixing the components with some of dried powder components missing; and adding a fire retardant component to replace the dry powder component wherein the fire retardant component is represented by melamine and melamine-polyphosphate.

Description

Technical field

The invention generally relates to paints and to methods of making paints.

BACKGROUND OF THE INVENTION

Paints are widely known and used in industry, households and other areas of modern life. Known paints typically include a film-forming binder component that provides film formation and adhesion to the substrate to which the paint is applied, and also include a color-forming component such as pigments and other coloring agents.

Although known paints provide some protection to the surfaces to which they are applied, they do not protect the surfaces of the substrates adequately from the effects of fire, and give certain colors to the surfaces to which they are applied. It is believed that it is appropriate to overcome this disadvantage.

It is therefore an object of the present invention to provide a paint that avoids the disadvantages of the prior art and provides a method for producing a paint.

SUMMARY OF THE INVENTION

In accordance with the objects mentioned above and other objects that will become apparent hereinafter, the present invention is based on a coating comprising a film-forming binder component, a color-forming component and a flame retardant component adapted to significantly protect the surface to which the paint is applied. applies.

When the coating composition of the present invention is in addition to the conventional characteristics, the coating also significantly protects the surface of the substrate to which it is applied from the effects of fire, in many cases increases the corrosion resistance and extends the life of the color coating.

According to another embodiment of the invention, the flame retardant component comprises at least one phosphate and / or a derivative thereof, such as melamine polyphosphate, ammonium polyphosphate.

According to another embodiment of the invention, the flame retardant component comprises melamine and / or a derivative thereof selected from the group consisting of melamine cyanurate, melamine borate, melamine polyphosphate, melamine diphosphate, melanine pyrophosphate and melamine phosphate.

The invention also provides a process for producing a paint comprising the steps of adding a film-forming binder component, adding a color-forming component, mixing the components, some of the dry components being absent, and adding a flame retardant component to replace the dry powder component.

The novel components considered to be characteristic of the present invention are set forth specifically in the appended claims. However, the invention itself, its description and mode of execution, together with other objects and advantages thereof, are best understood from the following description of specific embodiments.

According to the invention, there is provided a paint that comprises a film-forming binder component, a color-forming component, and a flame retardant component adapted to significantly protect the surface to which the paint is applied from fire.

- 1 GB 305026 B6

The flame retardant component may include a phosphate or a derivative thereof, such as melamine polyphosphate, ammonium polyphosphate.

The flame retardant component may also include melamine or a derivative thereof, such as melamine cyanurate, melamine borate, melamine polyphosphate, melamine diphosphate, melamine pyrophosphate and melamine phosphate.

In the paint of the invention, the flame retardant component may include a carbonizer such as pentaerythritol, mono-pentaerythritol or di-pentaerythritol and a swelling agent such as melamine and another agent selected from the group of agents specified above.

It is understood that, in addition to film-forming substances (binder materials and softeners), which are one of the major components of paints that affect durability, gloss, elasticity, bond, flexibility and hardness, as well as pigments, which may render color powders insoluble in carriers and soluble in coloring agents, thereby creating color variation and surface coloring ability, the paint may also contain volatile components which, in combination with binder materials, in most cases form a solution or so-called primer. Additives which are auxiliary chemicals forming the specific characteristics of the paints may also be included in the coating.

The coating paint of the invention may be made by a process comprising the steps of adding a film-forming binder component, adding a color-forming component, mixing these components, some of the dry components being absent, and adding a flame retardant component to replace the dry powder component.

In particular, fillers such as calcium carbonate and titanium dioxide are substituted flame retardants. Of course, however, it is possible to replace a small amount of film-forming component.

The paint according to the invention is described by means of the following examples.
