Description

Изобретение относитс  к строительным материалам и может быть применено при изготовлении строительных изделий и конструкций в транспортном строительстве. ,The invention relates to building materials and can be applied in the manufacture of building products and structures in transport construction. ,

Целью изобретени   вл етс  повышение прочности при изгибе.The aim of the invention is to increase the bending strength.

Технологи  приготовлени  композиции заключаетс  в следующем. Готов т рассчитанное количество св зующего, дл  чего мо- чевиноформальдегиднофурановую смолу и хлористый аммоний тщательно перемешивают в течение 2-3 мин. Дл  обеспечени  однородности отдельно готов т заполнитель путем перемешивани  рассчитанного количества песка и фосфогипса. Затем заполнитель и все компоненты тщательно перемешивают в течение 3-5 мин дополнительно. Полученную, композицию укладывают в формы, уплотн ют и выдерживают , например, в сушильном шкафу при 70°С в течение 2 ч. После чего издели  хран т в естественных услови х.The preparation technology of the composition is as follows. The calculated amount of binder is prepared, for which the urine-formaldehyde-furan resin and ammonium chloride are thoroughly mixed for 2-3 minutes. To ensure uniformity, the aggregate is separately prepared by mixing the calculated amount of sand and phosphogypsum. Then the aggregate and all components are thoroughly mixed for an additional 3-5 minutes. The resulting composition is placed in molds, compacted and kept, for example, in an oven at 70 ° C for 2 hours. After that, the products are kept in natural conditions.

Используемое в составе композиции мочевиноформальдегиднофурановое св зующее имеет условное.наименование БС-40 и удовлетвор ет следующим требовани м:The urea-formaldehyde-furan binder used in the composition has a conditional name BS-40 and satisfies the following requirements:

1.Внешний вид Однородна  жидкость от светло-желтого до темно-коричневого цвета. Допускаетс  присутствие взвеси и осадка.1. Appearance Uniform liquid from light yellow to dark brown. Suspension and sediment are allowed.
