## Abstract

The present invention consists of an aqueous putty or liquid suspension, formed by a mix of components a) and b) which are described as follows: a) an anhydrous silicate of an alkaline metal or alkaline terreous, in any of its forms (in dust, particles, granulates or fibers), or a hydrated silicate of an alkaline metal or alkaline terreous (in dust, particles, granulates or fibers), or a mix of both, b) a component of titanium, and optionally, in addition, of components c), d), e) and f), described as follows: c) one or more neutral or acid salts, of mono or poli ammonia, d) fungicide components, e) antibacterial components, and f) odor-controlling components. This putty can be utilized to stop or retard fire, as a coating or incorporated into granulated or aminated components, or in finished moulded products and similar items.

## Claims

### Claim 1

A fire retardant mix for coating or impregnation of wood and construction boards, wherein it contains anhydrous or hydrated silicates of an alkaline metal or alkaline terreous, or a mix of both, titanium dioxide and one or more neutral or acid salts of a poli ammonia, and containing optionally fungicide, antibacterial and odor-controlling components, wherein the salts of the ammonia used are those of bromides, sulphates and phosphates and the fire-retardant mix for coating or impregnation of wood and construction boards is inorganic.

### Claim 2 (depends on 1)

A fire retardant mix for coating or impregnation of wood and construction boards, as in claim 1, wherein the anhydrous silicates of an alkaline metal or alkaline terreous are fibers.

### Claim 3 (depends on 1)

A fire retardant mix for coating or impregnation of wood and construction boards, as in claim 1, wherein the fire retardant mix includes the fungicide which is boric acid in proportions ranging between 5% to 15% of the total weight of the mix.

### Claim 4 (depends on 1)

A fire retardant mix for coating or impregnation of wood and constructions boards, as in claim 1, wherein the silicates used are those of sodium, potassium and magnesium.

### Claim 5 (depends on 1)

A method of using the fire retardant mix of claim 1 for coating or impregnation of wood and construction boards comprising:
coating the fire retardant mix onto or incorporating the fire retardant mix into granulated or laminated wood components, joists, wooden boards known as oriented strand board (OSB), plywood, particle board, medium density fiberboard (MDF), high density fiberboard (HDF), hard board, fiber silicate mineral board, gypsum board, panels, or finished moulded products, moulded door skins, and furniture.
