Fireproof door core plate sheet material and preparation method thereof

Abstract

The invention discloses a fireproof door core plate sheet material. The fireproof door core plate sheet material is prepared from the following components in parts by weight: 5-30 parts of reinforced fibers, 2-10 parts of bentonite, 6-30 parts of an adhesive, 10-25 parts of inorganic gel material, 1-12 parts of an adhesion agent, 1-10 parts of fireproof expansion blocking material, 0.2-2 parts of a waterproof agent and 150-260 parts of water, wherein the adhesion agent has the effect of promoting the compatibility and the foaming effect of all the raw materials and the adhesive and the inorganic gel material are used for keeping generated foam; and the reinforced fibers have the effect of endowing the materials with certain flexibility and good mechanical strength. When the fireproof expansion blocking material suffers from a fire, the fireproof expansion blocking material expands to form a ceramic carbon layer to effectively block cracks which are formed when the sheet material suffers from the fire, and thus the fireproof door core plate sheet material has good heat insulation and fire smoke blocking performances. A preparation method of the fireproof door core plate sheet material is simple and convenient, is easy to operate and can be easily put into industrial production. The fireproof door core plate sheet material has the characteristics of small volume-weight, long fireproof time, no moisture absorption, no halogenation and the like.

Description

technical field [0001] The invention relates to the technical field of building materials and building fire protection. It specifically relates to a fire door core plate that can be used for various fire doors (steel, wood, steel and wood, etc.) and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the process of urbanization is accelerating, and a large number of high-rise buildings in cities are emerging. With the continuous increase of high-rise buildings, in recent years, the fires in high-rise buildings in my country have become more and more serious. Due to the difficulty of fire rescue and extinguishing in high-rise buildings, high-rise fires often lead to serious casualties, serious economic losses and other consequences, causing great social impact. Therefore, when a fire occurs, how to block the fire, delay the spread of the fire, and buy time for the people in the fire to escape and the firefighting f...

Problems solved by technology

However, these fire door core boards have certain problems in practical applications, such as: magnesite fire door core boards have problems of returning brine and moisture, corroding the door boards; expanded vermiculite boards and expanded perlite boards have poor toughness, fragility and large volume and other problems; foamed cement boards have problems such as easy water absorption, fragility and poor fire resistance

[0005] The Chinese Invention Patent with the publication number CN103214228A and the publication date of July 24, 2013 discloses an inorganic fire-proof and thermal insulation material and its preparation method. Although this new type of fire-proof board has basically solved the above problems, it has The board will deform and produce irregular cracks, which will eventually cause the board to fail to maintain good heat insulation and integrity after being exposed to fire for a long time, and fail to meet the national standard requirements for Class A fire doors
