Abstract

Изобретение относитс  к строительным материалам и предназначено длч изготовлени  декоративно-изол ционных изделий дл  внутренней отделки зданий. Иель изобретени  - повышение прочности при сохранении объемной массы, снижение горючести и температуры термообработки изделий. Сырьева  смесь дл  изготовлени  теплоизол ционных изделий содержит, мас.%: карбамидоформальдегидна  смола 52-60; ацетилсалицилова  кислота 0,5-1,2- бикарбонат аммони  1,0-3,0; вспученный перлит остальное. Горючесть изделий по потере массы в огневой трубе составл ет 16,7-18,5%, температура термообработки 100-120 C. 2 табл..The invention relates to building materials and is intended for the manufacture of decorative and insulating products for interior decoration of buildings. The invention is an increase in strength while maintaining the bulk density, reducing the flammability and temperature of heat treatment of products. The raw material mixture for the manufacture of thermal insulation products contains, wt%: a urea-formaldehyde resin 52-60; acetylsalicylic acid 0.5-1.2-ammonium bicarbonate 1.0-3.0; expanded perlite else. The flammability of the products by mass loss in the fire tube is 16.7-18.5%, the heat treatment temperature is 100-120 C. Table 2.

Description

Изобретение относитс  к производ- |ству строительных материалов, а именно к сырьевой смеси дл  изготовлени  декоративно-изол ционных изделий дл  внутренней отделки стен и потолков промышленных, культурко-оытовых, административных зданий.The invention relates to the production of building materials, namely, a raw material mixture for the manufacture of decorative insulating products for interior decoration of walls and ceilings of industrial, cultural, administrative and administrative buildings.

Цель изобретени  - повышение прочности при сохранении объемной массы, снижение горючести.и температуры термообработки .The purpose of the invention is to increase the strength while maintaining the bulk density, reducing flammability and heat treatment temperature.

Составы смеси и их физико-механические показатели приведены в табл.1 и 2.The compositions of the mixture and their physico-mechanical parameters are given in Tables 1 and 2.

Технологи  изготовлени  изделий из предлагаемой сырьевой смеси следующа  .The technology of manufacturing products from the proposed raw mix is as follows.

Смесь ацетилсалициловой кислоты и бикарбоната аммони  перемешивают с карбамидоформальдегидной смолой, затем ввод т вспученный перлит, перемешивают до гомогенизации и формуют с последующей сушкой при 100-120 С.A mixture of acetylsalicylic acid and ammonium bicarbonate is mixed with a carbamide-formaldehyde resin, then expanded perlite is introduced, mixed until homogenized, and molded, followed by drying at 100-120 C.

Как видно из полученных данных, предлагаемый состав по сравнению с известным при одинаковой плотности обладает высокими прочностными показател ми , низкой горючестью и низкой температурой термообработкиAs can be seen from the obtained data, the proposed composition, as compared with the known one, with the same density, has high strength characteristics, low flammability and low heat treatment temperature.
