Problems solved by technology

[0002] General magnesium cement is made by mixing magnesium oxide and magnesium sulfate. It has the characteristics of light weight, fire prevention, fast setting speed, good sound insulation effect, and high heat insulation efficiency. However, magnesium cement has strong thermal expansion during the curing process, and is easy to deform and crack. , The mechanical strength is low, so the promotion and application of this magnesium cement are limited, so that the characteristics of magnesium cement can be changed by developing modifiers

Abstract

The present invention discloses a modified magnesium cement, which comprises the following raw materials by weight: 100 parts of magnesium oxide, 40-150 parts of a magnesium sulfate aqueous solution having a concentration of 30-55%, 0.1-15 parts of a modifier, and 0-300 parts of a filler, wherein the modifier is citric acid or sodium citrate. According to the present invention, the time of the reaction of the magnesium oxide in the magnesium cement and the magnesium sulfate aqueous solution can be effectively shortened, the magnesium cement cementing strength is high, the compression resistance of the product is good, the rigidity of the product is strong, and the modified magnesium cement can meet the use requirements in fields of industry, agriculture, building, building materials, civil, and the like.

Description

technical field [0001] The invention relates to a magnesium cement material used in fields such as industry, agriculture, construction, building materials and civil use, in particular to a modified magnesium cement. Background technique [0002] General magnesium cement is made by mixing magnesium oxide and magnesium sulfate. It has the characteristics of light weight, fire prevention, fast setting speed, good sound insulation effect, and high heat insulation efficiency. However, magnesium cement has strong thermal expansion during the curing process, and is easy to deform and crack. , The mechanical strength is low, so the promotion and application of this magnesium cement is limited, so the characteristics of magnesium cement can be changed by developing modifiers. Contents of the invention [0003] In order to overcome the inherent shortcomings of magnesium cement and improve the performance of magnesium cement, the invention provides a modified magnesium cement.
