Abstract

The invention belongs to the technical field of fireproof materials, and particularly relates to a high-temperature-resistant fireproof core board and a manufacturing method thereof. The high-temperature-resistant fireproof core board is characterized by comprising the following components in parts by weight: 25-40 parts of water, 10-20 parts of magnesium sulfate, 40-60 parts of magnesium oxide, 0.1-0.8 part of polyester fiber, 1-2 parts of polyurethane adhesive, 2-3 parts of vitrified microbead, 0.01-0.05 part of modifier, 0.01-0.1 part of commercially pure phosphoric acid and 0.1-0.6 part of commercially pure acrylic acid. The high-temperature-resistant fireproof core board has the advantages of favorable fireproofness, favorable flame retardancy, high strength, low heat conductivity coefficient, high chemical stability, wide application temperature range, low moisture absorption capacity, no toxicity or odor and sound absorption. The high-temperature-resistant fireproof core board uses magnesium sulfate instead of magnesium chloride as the conditioner, can completely avoid the problems of halogen returning, moisture absorption, scumming and the like in the prepared board. The manufacturing cost of the high-temperature-resistant fireproof core board is lower, and the manufacturing method is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of fireproof materials, and in particular relates to a high-temperature-resistant fireproof core board and a manufacturing method thereof. Background technique [0002] At present, in order to improve the fire resistance performance of wooden fire doors, inorganic fireproof boards are used as lining boards on the door leaves and door frames of wooden fire doors. The specific hierarchical structure is: press and paste a layer of inorganic fireproof board of a certain thickness on both sides of the wooden door frame, and then press and paste a certain thickness of wooden fireproof plywood on the outside of the inorganic fireproof board; press and paste on the fire-receiving surface of the wooden door frame A layer of inorganic fireproof board with a certain thickness also needs to be pressed and pasted with a certain thickness of wooden fireproof plywood on the outside of the inorganic fireproof board. The fi...
