Description

Technical field

The invention relates generally to flame retardant paints and to a process for the manufacture of such paints.

BACKGROUND OF THE INVENTION

Paints are widely known and used in industry, households and other areas of modern life. Known paints usually include a film-forming compound which 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 for surfaces to which they are applied against the adverse effects of the atmosphere and impart certain colors to the surfaces to which they are applied, they do not protect the substrate surfaces adequately from the effects of fire. It is believed 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 these objects and other objects which become apparent hereinafter, the present invention provides a flame retardant paint for coating a surface of a predetermined color tint, comprising a film-forming binder component, a color component, fillers and additives, further comprising: comprising an effective amount of a flame retardant component, wherein the flame retardant component comprises at least one phosphate or derivative thereof, a carbonifying agent and melamine or a derivative thereof selected from the group consisting of melamine cyanurate, melamine borate, melamine polyphosphate, melamine pyrophosphate, melamine pyrophosphate and melamine phosphate. The effective amount of the flame retardant is at most 20% by weight. % of the color, preferably not more than 15 wt. color.

It has been found to be advantageous if the flame retardant component comprises at least one phosphate or a derivative thereof selected from the group consisting of melamine polyphosphate, melamine diphosphate, melamine pyrophosphate and melamine phosphate. According to another embodiment of the present invention, the flame retardant component comprises pentaerythritol and a derivative thereof selected from the group consisting of mono-pentaerythritol and dipantaerythritol as carbonizer.

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

The phosphorus content of the paint is at most 2% by weight. % of the total amount of paint, preferably at most 1.5 wt. of the total amount of color.

The invention also provides a process for producing a paint comprising the steps of adding a film-forming binder component; adding a coloring agent; mixing the ingredients, wherein some dry ingredients are absent; and adding a flame retardant component to replace the dry powder component.

When the paint is constructed according to the invention, in addition to the conventional characteristics, the paint also significantly protects the surface of the substrate to which it is applied against the effects of fire, in many cases increases the corrosion resistance and extends the lifetime of the paint.

The novel features which are considered to be characteristic of the present invention are set forth in particular in the appended claims. However, the invention itself, as well as its explanation and mode of operation, together with other objects and advantages, will be best understood from the following description of specific embodiments.

Description of preferred solutions

In accordance with the present invention there is provided a paint which 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.

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

The flame retardant 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 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 herein.

It should be understood that in addition to the film-generating substances (binder materials and plasticizers), which are one of the major components of paints that affect durability, gloss, elasticity, binding, flexibility and hardness, as well as pigments by which color powders may be insoluble in binders and soluble in coloring agents, thereby producing color variations and surface coloring properties, the paint may also include 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 paint, can also be included in the paint.

The paint of the present invention may be produced by a process comprising the steps of adding a film-forming binder component; adding a coloring agent; mixing these ingredients, wherein some dry ingredients are absent; and adding a flame retardant component to replace the dry powder component.

In particular, fillers such as calcium carbonate and titanium dioxide are replaced by the flame retardant component. Of course, however, it is possible to replace small amounts of the film-generating component.

The paint according to the invention is illustrated by the following examples.
