Description

Изобретение относитс  к составам полимерминеральных смесей дл  производства строительных изделий и конструкций .The invention relates to polymeric mineral blends for the manufacture of building products and structures.

Цель изобретени  - повышение водостойкости .The purpose of the invention is to increase the water resistance.

Полимерминеральную смесь готов т следующим образом.The polymer mineral blend is prepared as follows.

После дозировки отдельных компонентов производ т помол фосфогипса с себациновой кислотой в шаровой мельнице в течение 20-25 мин до получени  порошка с удельной поверхностью 5300-6100 см2/г. Смесь фосфогипса и себациновой кислоты смешивают в смесителе с карбамидной смолой, гидролизным лигнином, стекловолокном и водой в течение 2-2,5 мин до получени  однородной массы. Полученную смесь заливают в формы и уплотн ют на виброплощадках в формы в течение 30-50 с. Отверждение составов осуществл ют поAfter dosing the individual components, phosphogypsum is milled with sebacic acid in a ball mill for 20-25 minutes to obtain a powder with a specific surface of 5300-6100 cm2 / g. The mixture of phosphogypsum and sebacic acid is mixed in a mixer with a urea resin, hydrolysis lignin, fiberglass and water for 2-2.5 minutes until a homogeneous mass is obtained. The mixture obtained is poured into molds and compacted on vibrating platforms into molds within 30-50 seconds. The curing of the compositions carried out on

ч, термостатирование при 80-90 Сh, temperature control at 80-90 С

6 ч, охлаждение 3 ч.6 h, cooling 3 h.

Готов т полимерминеральные смеси, составы которых приведены в таблЛ.Polymer-mineral mixtures are prepared, the compositions of which are listed in Table L.

Дл  приготовлени  составов исполь- зуют карбамидоформальдегидную смолу КФ-К (ГОСТ 14231-78); стекловолокно марки БВ-8 (ГОСТ 10727-75).To prepare the compositions, urea-formaldehyde resin KF-K (GOST 14231-78) is used; fiber glass brand BV-8 (GOST 10727-75).

Результаты испытаний предлагаемой полимерминеральной смеси и известной представлены в табл. 2.The test results of the proposed polymer-mineral mixture and known are presented in table. 2
