High-temperature-resistant high-strength fireproof door panel and manufacturing method thereof

Abstract

The invention discloses a high-temperature-resistant high-strength fireproof door panel. The high-temperature-resistant high-strength fireproof door panel comprises the following raw materials in parts by weight: 50-80 parts of foaming agent, 30-40 parts of perlite powder, 20-30 parts of ore filler, 10-14 parts of magnesium sulfate, 14-18 parts of magnesium oxide, 3-5 parts of expansible graphite, 4-6 parts of zinc borate, 8-12 parts of calcium hydroxide, 25-35 parts of adhesive, 10-16 parts of desulfurized gypsum, 4-6 parts of boron oxide, 15-25 parts of reinforced fibers and 10-14 parts of anti-cracking fibers. The fireproof door panel disclosed by the invention has relatively good high temperature resistance and waterproof performance, is relatively strong in heat insulation and fire smoke resistance, is relatively good in mechanical performance indexes such as pressing resistance and bending resistance, is green and environmentally friendly, is light and is high in strength, and achieves the requirements of fireproof combustion and safety; and meanwhile, raw material components are safe and reliable, are harmless on environment, and are easily available, the cost is relatively low, the process is simple and clear, operation is easy and industrial production is easily realized, a practical value is higher and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of fire door materials, in particular to a high-temperature-resistant high-strength fire door core plate and a preparation method thereof. Background technique [0002] At present, with the development of the national real estate industry, the demand for fireproof building materials is getting wider and higher, and the requirements are getting higher and higher. Fire doors have multiple functions and practicability such as closure, fire resistance, partition, safety, heat preservation, and sound insulation. The fire door implements a license system. The production of fire doors must obtain the production license issued by the State Fire Administration. The fire door core plate is an essential core material for fire doors. It needs to be inspected by relevant departments in terms of combustion performance and safety performance. Higher conditions are put forward for the production of fire door core panels. ...

AI Technical Summary

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

[0004] To sum up, at present, there is no ideal door core panel product in the market that can satisfy fire door manufacturers.
