СП Изобретение относитс к cTpoirrenbным материалам, а более конкретно к составам дл изготовлени теплоизол онных изделий. HsteecTeH состав дл изготовлени теплоизол ционных изделий, включающий , мае. %: каолиновое волокно (7090 ) и алюмохромофосфатное св зу щее (10-30) 1 . Однако издели из этого состава имеют недостаточные морозо- и химическую стойкость, что ухудшает эксплу атационные показатели изделий. Известна сырьева смесь дл изготовлени теплоизол ционных изделий, включающа , мае. % доломитомергелис тое волокно (75-92); алюмохромофос фатное св зующее (5,5-15) и бутадие с ирольный латекс СКС-65 (2,510 ) t2j . Издели из этой смеси имеют недо точную прочность. Целью изофетени вл етс повыш ние прочности теплоизол ционных изде лий. Поставленна цепь достигаетс тем что сырьева смесь дл изготовлени теплоизол ционных изделий, включающа доломитомергелистое волокно, алюмохр фосфатное св зующее и бутадиен-стирольный латекс СКС-65, дополнительн содержит полнвиниладетаггную эмульсию при следукщем соотношении компонентов , мае. %: Доломитомергелистое ВОЛОКНО75-92 Алкжюхромофосфатное св зующее4,5-13 Бутади ен-с тирольный латекс СКС-65 2-8 Поливишшацетатн а эмульси 1,5-4 Образцы теплоизол ционного издели из предлагаемой смеси изготавливают следукщим образом. В смеситель зали вают 5О%-ную водную эмульсию апщум хромфосфатного св з ощего (АХФС), бутадиен-стирольный латекс СКС-65, 4S поливиниладетатную эмульбию и перемешттают в течение 4 мин. Затем полученный раствор пульверизацией вврд т в минераловатныи ковер из доломитомер гелистого Волокна следующего химического состава: SiOj. 46,94; А6а.0з 18,8; Ре2рз5,22; СаО 23,4; МрО 1,52; ,54; К.рз2.58. Пропитанный св зующим минераловат ный ковер подвергают тепловой обработ ке путем прососа теплоносител с темпе-, ратурой 18О®С в течение 1О-15 мин. Конкретные примеры сосхгавов предлагаемой и известной сырьевой смеси дл изготовлении теплоизол ционных изделий указаны в табл. 1. Физико-технические показатели издели из предлагаемой и известной сырьевой смеск указаны в табл. 2. Из табл. 1 и 2 следует, что оптимальным составом предлагаемой сырьевой смеси вл ютс составы 2-4. Издели из сырьевой смеси составов .1 и 5 имеют ухудшение физико-механических показателей. Эго объ сн етс тем, что в составе 1 указанного количества св зующего недостаточно дл покрыти минераловатного ковра ид доломитомергелистого волокна, что и приводит к уменьшению адгезии ме сду волокном и св зующим; в составе 5 излишнее количество св зующего приводит к разрушению образцов изделий по затвердевшему св зующему , которое без необходимого количества Волокон так же имеет низкие адгезионные свойства. Поливинилацетатна эмульси в предлагаемой сырьевой смеси дл изготовлени теплоизол ционных изделий повыщает пластические деформации пленки во врем ее усадки и снижает температуру остекловывани св зующего, что и позвол ет уменьшить внутренние напр жени и увеличить прочность и долговечность изделий . Из табл. 2 следует, что прочность при сжатии изделий из предлагаемой сырьевой смеси превышает прочность изделий из известной смеси.The invention relates to cTpoirrenb materials, and more specifically to compositions for the manufacture of thermal insulation products. HsteecTeH composition for the manufacture of thermal insulation products, including May. %: kaolin fiber (7090) and aluminum-chromophosphate binder (10-30) 1. However, products of this composition have insufficient frost and chemical resistance, which impairs the operational performance of products. The known raw material mixture for the manufacture of thermal insulation products, including May. % dolomitomergel fiber (75-92); alumos-chromophos phate binder (5.5-15) and butadiene with irolic latex SKS-65 (2.510) t2j. Products from this mixture have inadequate strength. The purpose of izofeteniya is to increase the strength of thermal insulation products. The delivered chain is achieved by the fact that the raw material mixture for the manufacture of thermal insulation products, including dolomite gelgel fiber, aluminum phosphate binder, and styrene-butadiene-styrene latex, SKS-65, additionally contains a full-vintable emulsion with the following ratio of components, May. %: Dolomitomergelous FIBER 75-92 Alkzhuhromofosfatnogo binder 4.5–13 Butadiene en-tyrol latex SKS-65 2-8 Polyvish acetate and emulsion 1.5–4 Samples of the heat-insulating product are made of the proposed mixture as a result. A 5O% aqueous emulsion of apchum chromophosphate coupling (AHFS), styrene-butadiene-styrene latex SKS-65, 4S, polyvinylaminetate emulsion is poured into the mixer and mixed for 4 minutes. Then, the resulting solution by spraying of the mineral wool into the mineral wool carpet made of dolomitomer of gelled fiber of the following chemical composition: SiOj. 46.94; A6a.0z 18.8; Pe2pz5,22; CaO 23.4; MRO 1.52; , 54; K.rz2.58. The mineral wool carpet impregnated with a binder is heat treated by heating the substrate with a temperature of 18 ° R for 1 0 –15 min. Specific examples of the proposed and known raw material mixtures for the manufacture of thermal insulation products are listed in Table. 1. Physical and technical indicators of the product from the proposed and known raw mix are shown in Table. 2. From table. 1 and 2, it follows that the optimal composition of the proposed raw mix is 2-4. Products made from raw mixes of compositions .1 and 5 have a deterioration in physico-mechanical parameters. This is explained by the fact that, in the composition of 1, the specified amount of the binder is not enough to cover the mineral wool of the id of dolomitomergel fiber, which leads to a decrease in the adhesion between the fiber and the binder; in composition 5, an excess amount of binder leads to the destruction of product samples by the hardened binder, which, without the required amount, Fibers also has low adhesive properties. The polyvinyl acetate emulsion in the proposed raw material mixture for the manufacture of thermal insulation products increases the plastic deformation of the film during its shrinkage and reduces the vitrification temperature of the binder, which reduces internal stresses and increases the strength and durability of the products. From tab. 2 it follows that the compressive strength of products from the proposed raw material mixture exceeds the strength of products from a known mixture.
