Abstract

FIELD: mining industry. SUBSTANCE: compositions are prepared with a solidification time of not more than 5 s at room temperature, an ultimate compression strength of 36.2 MPa, an adhesion to andesite porphyrite, a shrinkage of 6.7%, the content of harmful components in atmosphere when the composition is applied by a spraying method being lower than the permissible concentration. The effect can be attained by using 60-90 vol. parts carbamidoformaldehyde and 10-40 vol. parts of alkylresorcin resin, 4-10 vol. parts of urea, 2-6 vol. parts of semiaqueous gypsum based on 100 vol. parts of the mixture in the composition. The acid hardener includes 8-12 vol. parts of an aqueous oxalic acid solution having a concentration of 8-12% and 5-6 vol. parts of heteropolyacid. EFFECT: improved quality of the polymeric composition. 1 tbl

Description

Изобретение относится к горнодобывающей промышленности и может быть использовано для создания защитно-укрепляющих покрытий, например пород в горных выработках, а также в метростроении и гидротехническом строительстве. The invention relates to the mining industry and can be used to create protective and reinforcing coatings, for example, rocks in mining, as well as in metro and hydraulic construction.

Цель изобретения - снижение содержания вредных компонентов в рудничной атмосфере при нанесении композиции. The purpose of the invention is the reduction of harmful components in the mine atmosphere when applying the composition.

Предложенную полимерную композицию получают следующим образом. The proposed polymer composition is prepared as follows.

Мочевину растворяют в карбамидоформальдегидной смоле, затем добавляют алкилрезорциновую смолу ТСД-9 и полуводный гипс (алебастр) в соответствующих пропорциях и смесь перемешивают. Навеску гетерополикислоты растворяют в водном растворе щавелевой кислоты 8-12%-ной концентрации, после чего полученный кислотный отвердитель добавляют в основу. Urea is dissolved in urea-formaldehyde resin, then TSD-9 alkylresorcinol resin and semi-aqueous gypsum (alabaster) are added in appropriate proportions and the mixture is mixed. A portion of heteropoly acid is dissolved in an aqueous solution of oxalic acid of 8-12% concentration, after which the resulting acid hardener is added to the base.

В качестве гетерополикислоты используют кремнемолибденовую H8[Si(Mo2O7)6] ˙n H2O (ТУ 6-09-01-401-77), кремневольфрамовую H8[Si(W2O7)6] ˙n H2O (ТУ 6-09-3942-75), фосфорномолибденовую Н7[P(Mo2O7)6]˙n H2O (ТУ 6-09-3540-78), фосфорновольфрамовую Н7[P(W2O7)6] ˙n H2O (ГОСТ 18290-72). Составы и свойства известной и предлагаемой композиций и примеры для сравнения приведены в таблице.Silicon-molybdenum H 8 [Si (Mo 2 O 7 ) 6 ] ˙n H 2 O (TU 6-09-01-401-77), silicon-tungsten H 8 [Si (W 2 O 7 ) 6 ] ˙n are used as heteropoly acids H 2 O (TU 6-09-3942-75), phosphoromolybdenum H 7 [P (Mo 2 O 7 ) 6 ] ˙n H 2 O (TU 6-09-3540-78), tungsten phosphorus H 7 [P (W 2 O 7 ) 6 ] ˙n H 2 O (GOST 18290-72). The compositions and properties of the known and proposed compositions and examples for comparison are given in the table.
