preparation example Construction

[0020] A preparation method of lightweight fireproof partition slurry, comprising the following steps:

[0021] Step a: calcining magnesite at a temperature of 100-900°C to lightly burnt magnesia, then adding magnesium chloride solution, accompanied by crystallization, thereby generating strength;

[0022] Step b: adding fly ash to increase the volume of the product, reduce the amount of light-burned magnesia, reduce the weight of the product, and improve the performance of the product;

[0023] Step c: Add catalyst to the magnesium oxychloride material, and then introduce air to form uniformly distributed and self-closing bubbles, which can significantly reduce the weight of the product and improve the thermal insulation performance, frost resistance and sound insulation and sound absorption performance of the material. During the foaming process, because the fast setting can fix the bubbles, the bursting of the bubbles is greatly reduced, and the porosity of the material is ...

Abstract

The invention discloses light fireproof partition plate slurry and a preparation method thereof. The light fireproof partition plate slurry is prepared from the following raw materials: magnesium oxide, magnesium chloride, a glass fiber net, fly ash, palm fibers, a catalyst and water. The catalyst is prepared from the following raw materials in parts by weight: 9.3%-9.8% of sodium abietate, 6.5%-6.8% of sodium alpha-olefin sulfonate, 3.6%-4% of fatty acid diethanolamide, 1.7%-2% of sodium dodecyl benzene sulfonate, 0.2%-0.3% of sodium chloride, 0.2%-0.3% of sodium hydroxide and 75%-80% of water. The preparation method comprises the following step of: a, calcining magnesite at 100-900 DEG C to obtain light calcined magnesia, adding a magnesium chloride solution, and generating crystals under the accompanying condition, thereby generating strength. The light fireproof partition plate has the advantages of low weight, high strength, multiple environmental protection, heat preservation andinsulation, sound insulation, breathing humidifying, fire prevention, rapid construction, wall cost reduction and the like, the reasonably-arranged heat insulation and sound absorption inorganic foaming profiles or other heat insulation materials are arranged on the inner layer, and the wallboard is formed through assembly line pouring, leveling and scientific maintenance.

Description

technical field [0001] The invention relates to the technical field of fireproof partitions, in particular to a preparation method of lightweight fireproof partition slurry. Background technique [0002] Cement is a very important cementing material in lightweight wallboards. According to the composition of the main elements, it can be divided into two categories, namely calcium cement and magnesium cement. Calcareous cement mainly includes Portland cement and aluminate cement. And sulfoaluminate cement; magnesia cement is subdivided into magnesium oxychloride cement, magnesium oxysulfide cement, magnesium sulfate cement; they are all cementitious materials. [0003] my country is a country with a large magnesium resource. The solid mineral magnesium resource has 3.564 billion tons, accounting for 28.7% of the world's total resources, ranking first in the world. The economical use, rational use and comprehensive utilization of magnesium cementitious materials can improve the...
