Homogeneous fire-proof insulating plate and manufacture method thereof

Abstract

The invention provides a homogeneous fire-proof insulating plate and a manufacture method thereof. The method comprises the following steps: accurately weighing raw materials; adding a fire-proof flame-retardant inorganic material into a fire-proof flame-retardant adhesive, adding a dispersing agent, a coupling agent and a flame-retardant agent, and sufficiently stirring and dispersing; injecting a foaming agent into a mixer for foaming after the materials are sufficiently stirred and uniformly dispersed; mixing the material which is stirred and dispersed in the step 1 with expandable polystyrene particles, and sufficiently stirring and dispersing; homogenizing pulp after mixing and foaming, injecting into a flat mold, and placing on a multi-layer airing rack to naturally maintain for 10-15 hours; demolding, stacking for 10-15 hours, cutting, separating, polishing and leveling; and spraying codes on the surface, packaging and piling. The homogeneous fire-proof insulating plate has the characteristics of fire-proofing, heat-insulating and flame-retardant of inorganic materials and low heat conductivity coefficient of organic materials, and can be used for improving the fire-proof flame-retardant performance of a composite insulating material on the premise of not changing the heat conductivity coefficient of polystyrene.

Description

technical field [0001] The invention relates to a homogeneous fireproof and thermal insulation board, in particular to a homogeneous fireproof and thermal insulation board and a manufacturing method thereof. Background technique [0002] At present, the insulation materials used in the market include inorganic insulation materials and organic insulation materials. Organic insulation materials have better insulation performance, lighter capacity, and are easy to process, but have poor stability, are not resistant to aging and are easy to deform. Inorganic insulation materials include perlite, silicon Algae earth, rock wool, foam glass, slag wool, foamed cement board and a series of fireproof functions, although they have fireproof function, poor heat preservation, easy to powder, their own weight increases, some disadvantages of heavy weight. [0003] At present, there are two types in the market. One is a combination of inorganic materials such as glass wool, rock wool board...

AI Technical Summary

Problems solved by technology

However, although the organic insulation board is low in cost, good in insulation effect and convenient in construction, its combustion level is not up to the standard and will be eliminated by the market. Although it is possible to add flame retardants to the organic insulation board, the effect is not very obvious, and most of the When a fire occurs, it will produce toxic gas, which will cause suffocation and endanger life safety
