Abstract

To use the old known chemistry in a novel way to create a new product with unique properties that via an acid-base reaction to create a product that has a higher calorific value and hence greater protection. At via emulsified fish oil and binder (1-10%) and jodpræparat and cooking salt to improve the known issues brandimprægneringen without compromising on ecology and sustainability. Besides illiminere hygroskopien also to improve the protection against mildew and leaching or leaching of solids. In this way, to meet two essential factors, namely seepage to the surrounding environment as well as retention of the active substances in the wood To the accessory product to save industry resources by without priming to make subsequent treatment with a surface product.

Description

Mould preventive fire impregnation

The invention relates to a fire retardant liquid for impregnating cellulose-containing materials, including wood.

(DI) (US 200710037001A1) discloses a composition for stabilization of wood and wood products. The composition may also have a biocide and fire retardant properties. The composition comprising less than 25 percent by weight, water, biocides, flame retardants, as well as an oil. In relation to (Dl) (US 200710037001A1) differs this product in the composition, the composition of nitrogen and phosphorous compounds are 40 w / w%, fish oil is 10 W / W% and urea is 10 w / w%.

The novelty or the invention lies in: 1. To use the old known chemistry in a novel way to create a new product with unique properties 2. via an acid-base reaction to create a product that has a higher calorific value and hence greater protection.

3. In addition to eliminating hygroskopien also to improve the protection against mildew and leaching or leaching of solids. In this way, to meet two essential factors, namely seepage to the surrounding environment as well as retention of the active substances in the wood 4. with the product used to save industry resources by without priming to make subsequent treatment with a surface product.

5. The invention relates to a liquid - so-called fire retardant skimmmelhindrende liquid for use in the impregnation plant, the vacuum pressure at which there is a dosage of the process.

The mold preventive fire retardant liquid has several functions. It should reduce the surface tension of the water, to thereby increase the absorption in the wood. At the same time contribute to the ingredients that there is a fixing Thus, the liquid is inside the wood.

Fire impregnating liquid prepared as an acid-base reaction where in the process the fish oil is used which acts as binder. The reaction results in a mixture of salts having high active content of P and N as the fire safety, reduction-generating substances. The fish oil acts as a "binder" and helps ensure a stable emulsion, while after curing the fish oil helps to ensure that the active substances are fixed in the wood, and that it reduces leaching.

There exists today already flame retardants on the Danish market but none of these agents have the same manufacturing method. Common to these funds are also to apply the process technology but they are not suitable product technically. There is no fixation of the wood, which means that the timber occurs while the hygroscopic salts are washed out. This in turn means that brand value is reduced.

It has now been found that is possible to produce a fire retardant fluid that is environmentally friendly and non-toxic and where the fluid is in contrast to prior art compositions may be used for all types of cellulosic materials including wood and to any known impregnation forms, including . trvk. vacuum, dip, etc.

The fluid consists mainly of nitrogen and phosphorous compounds.

The invention thus relates to a fire retardant liquid, which can not burn consisting of:

Cellulosic materials, for example. Wood fire retardant shall have a maximum humidity of 25% and shall not be contaminated by visible mold or rot / fungus. The wood is placed on suitable vehicles which run into an impregnation tank (autoclave). Then establishes a vacuum. Then filled the autoclave with fire retardant liquid, then vacuum compensated. The creation of pressure in the autoclave. After moving fire retardant liquid back into the storage tank.

In order to ensure distribution of the liquid in the cellulose-containing material, for example. the timber and to minimize the liquid on the surface is established by a vacuum. The impregnated wood is run out of the autoclave and placed on a dedicated fixing space.

When the wood is dry handed it to the customer.

Fire impregnating liquid has the advantage that it reduces the surface tension and eliminating lime deposits from the water. Fire retardant liquid is temperature-stable and may be effective at lower temperatures. It is stable during transportation and storage, and finally it is with the addition of corrosion inhibitors are chemically inert to the bolts, nails, screws, etc.

Claims

1. Saline water-borne mold preventive fire retardant liquid, comprising:

2. Fire impregnating liquid according to claim 1 characterized in that salts of nitrogen and phosphorous compounds is defined as ammonium chloride, ammonium phosphate, diammonium phosphate.

3. The use of the mold preventing fire retardant liquid according to claim 1 or claim 2 for impregnating cellulose-containing materials, for example. wood desired fire and mold impregnated and thus fire and mold protected.
