Description

Изобретение относится к области производства строительных материалов на основе гипсового вяжущего.The invention relates to the production of building materials based on a gypsum binder.

Известен способ производства гипсовых плит, предполагающий использование массы, включающей, мас.ч.: вода 700; макулатура 15; двуводный гипс или фосфогипс 85; мочевиноформальдегидная смола 5; крахмал 2,5 [1].A known method of production of gypsum boards, involving the use of mass, including, parts by weight: water 700; waste paper 15; gypsum gypsum or phosphogypsum 85; urea-formaldehyde resin 5; starch 2.5 [1].

Задача изобретения состоит в снижении теплопроводности гипсовых плит, полученных из массы.The objective of the invention is to reduce the thermal conductivity of gypsum boards obtained from the mass.

Технический результат достигается тем, что масса для производства гипсовых плит, включающая воду, макулатуру, двуводный гипс или фосфогипс, мочевиноформальдегидную смолу, крахмал, дополнительно содержит пыль от переработки лубяных волокон, при следующем соотношении компонентов, мас.ч.: вода 680-720; макулатура 17-19; двуводный гипс или фосфогипс 83-87; мочевиноформальдегидная смола 4,8-5,2; крахмал 1,6-1,8; пыль от переработки лубяных волокон 6-8.The technical result is achieved in that the mass for the production of gypsum boards, including water, waste paper, two-water gypsum or phosphogypsum, urea-formaldehyde resin, starch, additionally contains dust from the processing of bast fibers, in the following ratio of components, parts by weight: water 680-720; waste paper 17-19; gypsum gypsum or phosphogypsum 83-87; urea-formaldehyde resin 4.8-5.2; starch 1.6-1.8; dust from the processing of bast fibers 6-8.

Пыль от переработки лубяных волокон (льна, пеньки, джута, кенафа) на 50-90% состоит из частиц размером до 4 мкм и содержит значительное количество минеральных веществ, %: 14-73 при переработке стланцевой льнотресты; 17-53 при переработке моченцовой тресты; 12-75 при выработке льняного луба. Примесь свободной двуокиси кремния в пыли составляет от 4 до 58%.The dust from the processing of bast fibers (flax, hemp, jute, kenaf) for 50-90% consists of particles up to 4 microns in size and contains a significant amount of mineral substances,%: 14-73 when processing shale linen flakes; 17-53 in the processing of a diarrhea trust; 12-75 when producing flax bast. The admixture of free silica in the dust is from 4 to 58%.

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

Компоненты дозируют в требуемых количествах. Пыль от переработки лубяных волокон предварительно смешивают с двуводным гипсом или фосфогипсом. В процессе приготовления массы для производства гипсовых плит используют гидропушитель, в который подают воду, макулатуру, предварительно нарезанную на куски площадью 2-16 см3, и пыль, смешанную с двуводным гипсом или фосфогипсом.The components are dosed in the required amounts. Dust from the processing of bast fibers is pre-mixed with two-water gypsum or phosphogypsum. In the process of preparing the mass for the production of gypsum boards, a water extinguisher is used, into which water, waste paper, previously cut into pieces with an area of 2-16 cm 3 , and dust mixed with two-water gypsum or phosphogypsum are fed.

После распушивания макулатуры образовавшуюся массу перекачивают в емкость, где ее перемешивают в течение 10-15 мин с мочевиноформальдегидной смолой и крахмалом. Затем массу обезвоживают, формуют из нее плиты, которые сушат при температуре 70-75°С.After fluffing up the waste paper, the resulting mass is pumped into a container, where it is mixed for 10-15 minutes with urea-formaldehyde resin and starch. Then the mass is dehydrated, plates are formed from it, which are dried at a temperature of 70-75 ° C.

Теплопроводность гипсовых плит, полученных из предложенной массы, снижается на 3-5% в сравнении с плитами, изготовленными с применением массы [1]. При этом утилизируется лубяная пыль.The thermal conductivity of gypsum boards obtained from the proposed mass is reduced by 3-5% compared with plates made with the use of mass [1]. In this case, bast dust is disposed of.
