Abstract

The invention discloses a preparation method of a fireproof insulation board with high flexural strength, and belongs to the technical field of board preparation. A mixture of polyphenyl granules andvitrified beads is taken as a substrate; honey is used for modifying the mixture; self-made basalt fiber is modified by polyethylene glycol monostearate; basalt is pulled into fibrous structure basalt; after the basalt fiber is modified, the bonding strength of an interface can be enhanced greatly; the polyphenyl granules are prone to burn at a high temperature; surface modification is performed on magnesium cement by a silane coupling agent; magnesium cement has very high density in a setting and hardening process, and is taken as an interfacial bonding agent after being modified; internal pores of the insulation board are effectively filled with the granules; magnesium hydroxide and aluminum hydroxide are modified together through a titanate coupling agent TMC-201, so that the flame temperature is lowered; a flame-retardant pyrophosphoric acid acyloxy group in the titanate coupling agent TMC-201 is introduced, so that the fire retardancy of the insulation board is enhanced.

Description

technical field [0001] The invention discloses a preparation method of a high-bending-strength type fireproof and thermal insulation board, which belongs to the technical field of board preparation. Background technique [0002] The insulation board is easy to understand, it is a board for building insulation. The thermal insulation board is a rigid foam plastic board made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, mixed with heat and injected with a catalyst, and then extruded to form a rigid foam plastic board. It has moisture-proof and waterproof properties. Reduce the thickness of the building's outer envelope, thereby increasing the indoor usable area. [0003] The common types are: XPS insulation board: it is a rigid foam plastic board made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, heated and mixed while injecting catalyst, and then extruded. Its scientific name is extruded...
