Изобретение относитс к промышленности строительных материалов и может найти применение при изготовлении гипсовых изделий.The invention relates to the building materials industry and may find application in the manufacture of gypsum products.
Известны гипсовые в жущие,включающие полуводный гипс, добавку и воду l. Наиболее близким решением по достигаемому эффекту и технической сущности вл етс в жущее, включающее полуводный гипс, полиакрилаты и воду 2Known gypsum in living, including semi-aquatic gypsum, additive and water l. The closest solution to the effect achieved and the technical essence is a gangway, including semi-aquatic gypsum, polyacrylates and water 2
Недостатком известных в жущих вл етс низка додостойкость изделий и короткие сроки схватывани .A disadvantage of the known in the gnaw is a low dodging resistance of the products and a short setting time.
Цель изобретени - увеличение сроков схватывани гипса и повышение водостойкости .The purpose of the invention is to increase the setting time of gypsum and increase water resistance.
Это достигаетс тем, что в жущее в качестве добавки содержит сополимер акриловой или метакриловой кислоты с дубителем в отношении от 0,3:1 до 0,7:1, при следующем соотношении компонентов , вес.ч.:This is achieved by including in the quality of the additive an acrylic or methacrylic acid copolymer with a tanning agent in the ratio from 0.3: 1 to 0.7: 1, in the following ratio of components, parts:
Полуводный гипс 100-150Semi-aquatic gypsum 100-150
Сополимер акриловойAcrylic copolymer
или метакриловойor methacrylic
кислоты с дубителем 0,005-0,05acids with a tanning agent 0.005-0.05
вода35-100.water 35-100.
В качестве дубителей могут быть использованы экстракты дуба, ели, ивы.. Extracts of oak, spruce, willow can be used as tanning agents.
Ь жущее может характеризоватьс различными составами.B A brute may be characterized by different compositions.
Пример 1. В растворомешалку вливают 35 вес.ч. воды и 0,005 вес.ч, (в пересчете на сухое вещество) сополимера акриловой кислоты с дубителем. В полученный раствор всыпают 100 вес.ч. полуводного гипса и перемешивают в течение 1-2 мин.Example 1. In the mixer pour 35 weight.h. water and 0.005 wt.h, (in terms of dry substance) of acrylic acid copolymer with a tanning agent. In the resulting solution pour 100 weight.h. semi-aquatic gypsum and stirred for 1-2 minutes.
Приготовленную смесь вливают в формы .The mixture is poured into molds.
Пример2.В растворомешалке смешивают 100 вес.ч. воды и 0,05 вес.ч сополимера метакриловой кислоты дубителем . К полученному растворудобавл ют 150 вес.ч. полуводного гипса, перемешивают в течение 1-2 мин. И:заливают в формы.Example 2. In a mortar mixer mix 100 weight.h. water and 0.05 wt.h copolymer of methacrylic acid tanning agent. 150 parts by weight are added to the solution obtained. semi-aquatic gypsum, stirred for 1-2 minutes. And: poured into the form.
Полученные смеси характеризуютс следующими сроками схватывани : начало схватывани 6,30-22,00 мин, конец схватывани 9,00-28,00 мин. Прочность на сжатие образцов, высушенных до постоо нной массы после 28-ми суточног тверцени , составл ет 225-250 кгс/см , на изгиб 82-88 кгс/см.The resulting mixtures are characterized by the following setting times: the start of setting is 6.30-22.00 minutes, the end of setting is 9.00-28.00 minutes. The compressive strength of samples dried to constant weight after 28 days of Tversen is 225-250 kgf / cm, bending 82-88 kgf / cm.
