Abstract

The invention discloses a hydrophobic inorganic gel material, which is prepared from the following components in part by weight: 10 to 20 parts of magnesium oxychloride or magnesium oxide, 8 to 14 parts of saturated magnesium chloride or magnesium sulfate solution, 0.01 to 0.1 part of oxalic acid, 0.5 to 2.5 parts of retarder, 2 to 4 parts of plasticizer, 1.5 to 3 parts of cellulose, and 0.2 part of hydrophobic waterproof agent. The invention also discloses a preparation method for the hydrophobic inorganic gel material. The hydrophobic inorganic gel material is high in strength, flexible, fireproof, waterproof, halogenide-resistant, nontoxic, odorless, green, environment-friendly and difficult to crack.

Description

technical field [0001] The invention relates to a novel cement and a preparation method thereof, in particular to a hydrophobic inorganic gelling material made from integrated regeneration of waste resources and a preparation method thereof. Background technique [0002] The content of magnesium oxide or magnesium chloride in geology is very rich, and the content in my country accounts for about 65% of the world, but the utilization rate is less than one thousandth, which is a great waste of resources. The basic detection of the current magnesite cement technology is too complicated, which makes the various technologies of the entire industry backward and chaotic. The magnesite products produced by most enterprises are mostly inferior products that cannot meet the standards, which makes the whole society have a lot of magnesite products. Misinterpretation or even market rejection. This technology thoroughly modifies the original technology, making it easier for manufacturer...
