Graphite type homogeneous fireproof insulation board and manufacturing method thereof

Abstract

The invention provides a graphite type homogeneous fireproof insulation board and a manufacturing method thereof. The manufacturing method of the graphite type homogeneous fireproof insulation board includes the following specific steps that all components are accurately taken, fire-resistant anti-flaming type inorganic materials are added to a fire-resistant anti-flaming type adhesive, dispersant, a coupling agent and flame retardant are added, and full stirring and dispersing are conducted; after the mixture is fully stirred and dispersed to be uniform, a foaming agent is injected into a mixer for foaming; the material obtained after stirring and dispersing in the step 1 and expandable polystyrene particles are mixed and fully stirred and sieved, mixed foamed homogenous slurry is injected into flat-plate type dies and placed on multiple layers of airing racks for natural curing, curing time is 10-15 hours, and after die release, the slurry is stacked for 10-15 hours and then cut, slit, polished, leveled, subjected to surface treatment and code spraying, packaged and stacked. The graphite type homogeneous fireproof insulation board has the characteristics of fire resistance, heat insulation and flame retardance of the inorganic materials and the low heat conductivity coefficient of organic materials, and the fire-resisting anti-flaming performance of a composite insulation material can be improved on the premise that the heat conductivity coefficient of graphite polystyrene is not changed.

Description

technical field [0001] The invention relates to a homogeneous fireproof and thermal insulation board, in particular to a graphite-type 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, r...

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
