(57) Abstract:

The solution is to match industry and can be used in the preparation of protivoklescheve solution for impregnation match wood. Impregnating protiviti solution to match wood as a flame retardant contains ammonium polyphosphates with the content of total P2O51,0-2,5%. The technical result is to increase efficiency through the use of cheaper flame retardant. table 2.

The invention relates to match industry and can be used in the preparation of protivoklescheve solution for impregnation match wood.

Known protiviti solution for impregnation match wood containing flame retardant, in which the flame retardant used is phosphoric acid. (Typical technological modes of production matches the assertion. 29.03.90. The minlesprom the USSR, S. 178).

A disadvantage of the known technical solutions is the high cost of impregnation due to the use of expensive flame retardant.

Known protiviti solution for impregnation match wood containing flame retardant, in which the flame retardant used demonise high cost impregnation due to the use of expensive flame retardant.

The purpose of the invention is increased efficiency through the use of cheaper retardant.

This objective is achieved in that the impregnating protivitia solution to match wood containing flame retardant, the flame retardant contains ammonium polyphosphate, and the content of total P2O5it is 1.0 to 2.5%.

The invention has the following differences from the prototype:

impregnating protiviti solution to match wood as a flame retardant contains ammonium polyphosphates;

- the content of total P2O5in impregnating patiotism solution is 1.0 to 2.5%.

This improves efficiency at the expense of an impregnating composition.

In the above us patent information the Fund has not found similar technical solutions, and solutions with these distinctive features.

The invention is applicable and will be used at the enterprises of the match industry in 1999

For the preparation of impregnating protivoklescheve solution used ammonium polyphosphates, THE 2149-062-106-64-029-96;

Preparation of impregnating protivoklescheve solution is performed followed by the RA pour the ammonium polyphosphates and water to obtain a given composition of the solution for P2O5. The contents of the reactor was stirred at room temperature for 5-10 minutes Readiness of the solution is judged by the content of P2O5, density and pH.

Composition proteoclastic impregnation solutions according to the examples presented in table. 1.

The results of the impregnation are shown in table. 2.

Consumption of flame retardant when using ammonium polyphosphates for enterprises with a capacity of 8.8 million boxes./year less than the prototype 35-45 tons/year, and the expected economic effect from the use of flame retardant in the form of ammonium polyphosphates will be 1.5 - 2 million rubles/year.

Thus, the invention improves the efficiency through the use of cheaper flame retardant.

Impregnating protiviti solution to match wood containing flame retardant, characterized in that it contains flame retardant ammonium polyphosphates when the content of P2O5in the impregnating solution 1,0 - 2,5%.
