Abstract

The invention discloses an inorganic composite magnesium gelling material and application in the insulating case domain, which comprises the following parts: 100g MgO with content over 60%, 80-95% magnesium chloride with specific gravity at 1. 20-1. 24, 30-50% talcum powder, 1. 5-2% anti-halogen agent and 0-0. 5% soluble dye. The invention can improves solidifying speed, which possesses superior heat preservation and high strength.

Description

(1) Technical field [0001] The invention relates to the field of inorganic composite materials, in particular to a magnesia inorganic composite gelling material and its application in thermal insulation shells. (2) Background technology [0002] The development and application of magnesia-based inorganic composite materials are increasingly valued by people. At present, there are many types of such products at home and abroad, and their applications are relatively common. For example, in the building materials industry, there are fireproof boards, fireproof decorative Ventilation pipes, corrugated tiles, etc.; in the municipal industry, there are garbage bins, water meter boxes, pit covers, etc.; in the machinery industry, there are packaging boxes, inorganic non-combustible cable troughs, etc.; in agriculture, there are vegetable sheds, grain storage bins, etc. However, due to the unstable performance of the existing magnesia gelling materials and the immature application t...
