Products have average density of 6690-7230 kg/cubic m. Water absorption is 0.15-0.18 % for 24 h. EFFECT: increased average density and lower water absorption of the material. 1 tbl

Description

Изобретение относится к строительным материалам и может быть использовано для изготовления строительных деталей и изделий, предназначенных для защиты от ионизирующих излучений. The invention relates to building materials and can be used for the manufacture of building parts and products designed to protect against ionizing radiation.

Известна сырьевая смесь для изготовления строительных конструкций и изделий (а.с. N 1650637, C 04 B 28/36), включающая серу, добавку, наполнитель и заполнитель при следующем соотношении компонентов, мас.%:
Сера - 10,8 - 12,8
Тонкомолотый наполнитель - 9 - 13
Кубовые остатки крекинга нефти - 0,1 - 0,26
Нефтебитуминозный бархатный песок - 4 - 6
Заполнитель - Остальное
Наиболее близкой к изобретению является композиция (патент N 2105739, C 04 В 28/36) для изготовления строительных изделий, включающая следующие компоненты, мас.%
Сера - 14-16
Наполнитель (отход производства оптического стекла с удельной поверхностью 2000 - 2200 см2/г) - 28 - 42
Заполнитель (тот же отход с размером частиц 0,6-1,25 мм) - 42-58
Однако, для указанных материалов характерно невысокое значение средней плотности, а также значительное водопоглощение.Known raw mix for the manufacture of building structures and products (and.with. N 1650637, C 04 B 28/36), including sulfur, additive, filler and aggregate in the following ratio of components, wt.%:
Sulfur - 10.8 - 12.8
Fine Filler - 9 - 13
Distillation residues of oil cracking - 0.1 - 0.26
Oil bituminous velvet sand - 4 - 6
Placeholder - Else
Closest to the invention is a composition (patent N 2105739, C 04 B 28/36) for the manufacture of building products, comprising the following components, wt.%
Sulfur - 14-16
Filler (waste product for the production of optical glass with a specific surface area of 2000 - 2200 cm 2 / g) - 28 - 42
Aggregate (the same waste with a particle size of 0.6-1.25 mm) - 42-58
However, these materials are characterized by a low average density, as well as significant water absorption.

Цель изобретения - повышение средней плотности и снижение водопоглощения материала. The purpose of the invention is to increase the average density and reduce water absorption of the material.

Поставленная цель достигается тем, что композиция, включающая серу, добавку, наполнитель и заполнитель, в качестве заполнителя содержит свинцовую дробь с диаметром частиц 3 - 4 мм, а качестве добавки - парафин. This goal is achieved in that the composition, including sulfur, additive, filler and filler, contains lead fraction with a particle diameter of 3-4 mm as a filler, and paraffin as an additive.

Для изготовления композиции используют техническую серу (ГОСТ 127-76), парафин, свинцовую дробь и отход производства оптического стекла. Указанный отход содержит 71% PbO, истинная плотность отхода - 5100 кг/м3. Данный отход, измельченный до удельной поверхности 2000 - 2200 см2/г, использовали в качестве наполнителя.For the manufacture of the composition, technical sulfur (GOST 127-76), paraffin, lead shot and waste from the production of optical glass are used. The specified waste contains 71% PbO, the true density of the waste is 5100 kg / m 3 . This waste, crushed to a specific surface of 2000 - 2200 cm 2 / g, was used as a filler.

Использование свинцовой дроби, имеющей истинную плотность 11340 кг/м3, позволяет значительно повысить среднюю плотность композитов, а добавка парафина приводит к снижению водопоглощения.The use of lead shot, having a true density of 11340 kg / m 3 , can significantly increase the average density of the composites, and the addition of paraffin reduces the water absorption.

Композиция готовится следующим образом. В расплавленную при температуре 150- 160oC серу вводят добавку и нагретый до 140 - 150oC наполнитель. Смесь перемешивают до однородной массы. Затем вводят нагретый до 140 - 150oC заполнитель. Смесь тщательно перемешивают, 10 - 15 мин выдерживают при 150 - 160oC, укладывают в формы и вибрируют 10 - 15 с. После охлаждения в течение 30 - 40 мин формы подвергают распалубке.The composition is prepared as follows. The molten at a temperature of 150 to 160 o C sulfur additive is introduced and heated up to 140 - 150 o C excipient. The mixture is stirred until smooth. Then, aggregate heated to 140-150 ° C is introduced. The mixture is thoroughly mixed, kept for 10-15 minutes at 150-160 o C, laid in molds and vibrated for 10-15 seconds. After cooling for 30 to 40 minutes, the molds are stripped.

Составы предлагаемой композиции и свойства полученного материала приведены в таблице. The compositions of the proposed composition and the properties of the obtained material are given in the table.

Как видно из таблицы, предлагаемая композиция имеет более высокую (в 1,5 - 1,7 раза) среднюю плотность и более низкое (в 2,5 - 3 раза) водопоглощение по сравнению с известной композицией. As can be seen from the table, the proposed composition has a higher (1.5 - 1.7 times) average density and lower (2.5 - 3 times) water absorption compared with the known composition.
