Problems solved by technology
Polystyrene is used as thermal insulation material. Although its thermal insulation performance is good, its maximum applicable temperature is 40°C. When the temperature is high, it will shrink, decompose, and crack; the cost of foam glass and microporous calcium silicate thermal insulation materials is too high. high
In addition, the cement polystyrene insulation board is thick, the surface layer is easy to crack, and the polystyrene foam plastic is highly flammable, and the smoke is highly toxic, so it is not suitable for civil building interior decoration materials; Longer, affecting the progress of the project

Embodiment Construction
[0037] The raw materials of the composite insulation board of the present invention are waste phenolic foam powder, fly ash, expanded perlite, mineral wool, glass wool, sepiolite, palygorskite, neutral water glass as an inorganic binder, and organic The methyl cellulose of binding agent and water form, and raw material component is prepared by following mixing ratio (weight %):
[0038] Waste phenolic foam powder-15%; fly ash-7%; perlite-15%; sepiolite-10%; palygorskite-5%; mineral wool-10%; water glass-2.75%; Cellulose - 0.25%; Water - 35%.
[0039]Add water to palygorskite and mineral wool for high-speed dispersion, add sepiolite for stirring, then add neutral water glass and methyl cellulose to mix, then add waste phenolic foam powder, fly ash and perlite Mixing, final injection molding, forming and drying are made into the composite material insulation board of the present invention.

Abstract
The thermal insulating plate of composite material is produced with waste foamed phenolic plastic powder as basic heat insulating material, flyash as stuffing, expanded perlite as aggregate, mineral wool, glass wool, sepiolite and palygorskite as reinforcing material, neutral water glass or silica sol as inorganic adhesive and guar gum, methylcellulose or CMC as organic adhesive, and through high speed dispersion, stirring, mixing, molding, forming and drying. The thermal insulating plate has low heat conducting coefficient, is non-inflammable, smell-less, non-toxic, long in service life and wide in application range. The production process adopts industrial waste as main components and produces no waste, and used plate may be reused, so that the present invention is significant in environment protection.
Description
Technical field [0001] The invention relates to the technical field of thermal insulation materials for buildings and boiler pipes, in particular to the technical field of producing composite material thermal insulation boards by using industrial waste. Background technique [0002] Insulation materials refer to materials or material composites that are not easy to conduct heat and have significant resistance to heat flow. They are functional materials used to reduce heat exchange between structures and the environment. The thermal insulation performance of the material is determined by the thermal conductivity of the material. The smaller the thermal conductivity, the better the heat preservation and heat insulation performance. The characteristics of thermal insulation materials are light, loose, porous, some are fibrous, and have good thermal insulation and heat insulation effects. Usually refers to thermal insulation material refers to the density <350kg / m 3 , Mate...
