Preparation technology of inorganic foaming partition plate

Abstract

The invention relates to a preparation technology of an inorganic foaming partition plate. The preparation technology comprises the following steps that magnesium chloride and water are mixed, prepared to be bittern and added into a stirring machine, and PP fiber is added into the bittern; caustic-burned magnesia powder and modifying agent are added and continue to be stirred for 30s; efficient chemical foaming agent is added, the mixture continues to be stirred to be uniform, and slurry with completely-dissolved solid materials and uniform liquid surface foams is prepared; the bottom layer ofa die is coated with a plastic film, a layer of glass fiber gridding cloth is fully laid on the film on the bottom layer of the die, the prepared slurry is rapidly poured into the die, the surface ofthe die is also coated with a layer of glass fiber gridding cloth after the die is filled and coated with a layer of plastic film again, the die is locked, and standing is carried out at indoor temperature for 24h; and the die is removed, the upper surface, lower surface and periphery of the cured partition plate are each spread with a layer of anti-crack mortar. According to the technology, operation is easy, operation steps are simplified, building requirements are met, and meanwhile working efficiency is improved. The inorganic foaming partition plate prepared through the technology is lowin cost, and the manufacturing cost of enterprises is reduced.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a preparation process of an inorganic foamed partition board. Background technique [0002] Partition wall panels are lightweight slats for building partition walls, and are used as the main material for non-load-bearing inner partition walls in general industrial buildings, residential buildings, and public construction projects. With the continuous improvement of the level of construction technology, modern buildings are gradually developing towards high-rise buildings and large bays, and their functional requirements continue to increase. The overall requirements for the development of wall materials are light weight, high strength, space saving, thermal insulation, sound insulation, and construction efficiency.

Problems solved by technology

With the continuous improvement of the level of construction technology, modern buildings are gradually developing towards high-rise buildings and large bays, and their functional requirements continue to increase. The overall requirements for the development of wall materials are light weight, high strength, space saving, thermal insulation, sound insulation, and construction efficiency. High, with the deepening and expansion of wall reform, some new wall materials are also emerging, but the proportion of various partition boards only accounts for 3.4% of the total wall materials. The reason is that most of the partition boards The cost is high, the quality is poor, and the physical and mechanical properties such as material density, wall thickness, external dimensions, bending load, fire protection, and sound insulation cannot meet the requirements, resulting in relatively few applications of partition boards in the current construction field.
