Fireproof heat insulation plate and preparation method thereof

Abstract

The invention provides a fireproof heat insulation plate and a preparation method thereof. The fireproof heat insulation plate comprises 30 to 50 parts of polyether polyol, 4 to 10 parts of a flame retardant, 0.1 to 1 part of a catalyst, 1 to 5 parts of a chain extender, 5 to 15 parts of expandable graphite, 0.1 to 2 parts of a pigment, 0.1 to 3 parts of aerogel, 45 to 60 parts of a base material and 10 to 25 parts of a surface material. The fireproof heat insulation plate has the advantages of being stable in structure, good in protectiveness and capable of improving the heat insulation performance of the ultra-thin plate.

Description

technical field [0001] The invention relates to the technical field of fireproof sealing materials, in particular to a fireproof heat insulation board and a preparation method thereof. Background technique [0002] In the early days, wooden boards and other materials were used as partition boards or decorative boards. Due to the extremely low ignition point of wooden boards, once a fire accident occurred, not only could not gain more time for disaster relief, but it would cause greater casualties and losses due to the combustion-supporting effect. In order to reduce the occurrence of such disaster expansion, the industry and users have switched to fireproof panels as compartment decoration. Fire-proof and heat-insulating board, also known as fire-resistant board, is scientifically called thermosetting resin impregnated paper high-pressure laminate, and its English abbreviation is HPL (Decorative High-pressure Laminate). It is a refractory building material for surface decora...

Problems solved by technology

[0003] However, the fireproof and heat insulation boards currently used in the market are mainly mineral wool boards and rock wool boards. This kind of fireproof blocking board is limited by its own materials during use, and its strength is not enough and its load-bearing capacity is limited. After the material absorbs moisture, the structure of the fireproof blocking board is easy to collapse, causing secondary damage; the flying catkins produced during the production process of mineral wool board and rock wool board are easy to migrate in the environment and cause air pollution, and at the same time, it is harmful to the life and health of workers. Threat exists

In addition, when the board shape of the fire blocking board is thin, there is also the problem of poor thermal insulation performance
