Problems solved by technology

The existing fire door cores in China are mainly divided into two types. The first one is made of expanded perlite as the main raw material and is made by high temperature hot pressing process. This kind of fire door core board has low production efficiency, high cost, easy pulverization, High water absorption, and will pollute the environment during the production process
The second type of fire door core board made of magnesite cement as the main raw material will return to halogen during use, and its hardness will drop and it will be easily deformed. Magnesium chloride decomposes into chloride ions and magnesium ions, which will cause corrosion and rust of steel door panels and reduce the service life of the door
[0003] The fire door core board made of ordinary foamed cement has large drying shrinkage and high water absorption rate, resulting in a decrease in its hardness, which has a great impact on its fire performance

Abstract

The invention discloses a fireproof foamed cement door core plate and a making method thereof. The fireproof foamed cement door core plate comprises, by weight, 100-200 parts of Portland cement, 5-20parts of silica fume, 90-150 parts of water, 15-30 parts of an emulsifier, 6-12 parts of a high efficiency water reducer, 5-15 parts of a foaming agent, 5-10 parts of attapulgite clay and 1-2.5 partsof fibers, wherein the foaming agent includes, by weight, 100-150 parts of light magnesium oxide, 25-40 parts of lauryldimethylamine oxide, 20-30 parts of coconut diethanolamide, 5-50 parts of hydrogen peroxide, 0.1-10 parts of polyether modified silicone oil and 5-60 parts of water. The fireproof foamed cement door core plate has the advantages of low production cost, high strength, good waterproof property, good fireproof property, non-deformation and impermeability, and has a certain adsorption effect on formaldehyde, ammonia, benzene and other harmful gases in air in order to protect the environment and the body health of users.

Description

technical field [0001] The invention relates to the field of building products, in particular to a foamed cement fireproof door core board and a preparation method thereof. Background technique [0002] Fire doors have multiple functions and practicability such as closure, fire protection, partition, safety, heat preservation, and sound insulation, and have become an indispensable part of buildings. The existing fire door cores in China are mainly divided into two types. The first one is made of expanded perlite as the main raw material and is made by high temperature hot pressing process. This kind of fire door core board has low production efficiency, high cost, easy pulverization, The water absorption rate is high, and it will pollute the environment during the production process. The second type of fire door core board made of magnesite cement as the main raw material will return to halogen during use, and its hardness will drop and it will be easily deformed. Magnesiu...
