Description

Изобретение касается производства строительных материалов.The invention relates to the production of building materials.

Известна масса для производства плит, включающая, мас. ч.: вода 700; макулатура 15; двуводный гипс или фосфогипс 85; мочевиноформальдегидная смола 5; крахмал 2,5 [1].Known mass for the production of plates, including, by weight. h: water 700; waste paper 15; gypsum gypsum or phosphogypsum 85; urea-formaldehyde resin 5; starch 2.5 [1].

Задача изобретения состоит в сокращении расхода вяжущего в массе для производства теплоизоляционных плит.The objective of the invention is to reduce the consumption of binder in the mass for the production of heat-insulating boards.

Технический результат достигается тем, что масса для производства теплоизоляционных плит, включающая воду, макулатуру, фосфогипс, мочевиноформальдегидную смолу, крахмал, дополнительно содержит гидролизный лигнин и карбонатный песок, причем компоненты находятся при следующем соотношении, мас. ч.: вода 340-360; макулатура 160-200; фосфогипс 50-60; мочевиноформальдегидная смола 3-4; крахмал 2-3; гидролизный лигнин 3-4; карбонатный песок 160-200.The technical result is achieved in that the mass for the production of heat-insulating boards, including water, waste paper, phosphogypsum, urea-formaldehyde resin, starch, additionally contains hydrolysis lignin and carbonate sand, and the components are in the following ratio, wt. h: water 340-360; waste paper 160-200; phosphogypsum 50-60; urea-formaldehyde resin 3-4; starch 2-3; hydrolysis lignin 3-4; carbonate sand 160-200.

В таблице приведены составы массы для производства теплоизоляционных плит.The table shows the composition of the mass for the production of insulating boards.

В процессе приготовления массы для производства плит используют гидропушитель, в который подают воду (с избытком) и макулатуру, предварительно нарезанную на куски площадью 2-16 см2. После распушивания макулатуры из образовавшейся массы удаляют излишнее количество воды, перекачивают ее в емкость, где массу перемешивают в течение 10-15 мин с мочевиноформальдегидной смолой, крахмалом. Затем добавляют карбонатный песок, гидролизный лигнин фосфогипс и осуществляют перемешивание еще в течение 1-3 мин. Из приготовленной массы формуют плиты, которые сушат до влажности не более 5%.In the process of preparation of the mass for the production of plates using a water extinguisher, which serves water (in excess) and waste paper, previously cut into pieces with an area of 2-16 cm 2 . After fluffing up the waste paper, excess water is removed from the resulting mass, it is pumped into a container, where the mass is mixed for 10-15 minutes with urea-formaldehyde resin, starch. Then carbonate sand, hydrolysis lignin phosphogypsum are added and mixing is carried out for another 1-3 minutes. Plates are formed from the prepared mass, which are dried to a moisture content of not more than 5%.
