Problems solved by technology

However, it needs to be improved in terms of fire resistance, stability and fit.
The Chinese invention patent with the application number of 200910023626.3 discloses a porous iron tailings sintered insulation board, which uses a large amount of iron tailings and uses a mixture of sodium carbonate powder, silicon carbide powder, iron powder and calcium phosphate powder as a foaming agent. Borax, potassium feldspar, albite feldspar or lead oxide are used as flux, and the prepared board has a certain degree of improvement in high strength and thermal insulation performance, but in terms of fire retardant and bonding with the base layer of the wall needs improvement

Abstract

The invention provides a graphene and stone tailing based foaming light heat insulation board. The graphene and stone tailing based foaming light heat insulation board is prepared from the following components of a stone tailing, clay, graphene, calcium carbonate, vermiculite, a high temperature cosolvent, expanded graphite, a stabilizer, a dispergator and a pigment. The heat insulation board usesthe stone tailing as the base material, the graphene and the vermiculite are added, then the board better achieves the advantages of light weight, high strength and heat insulation, the performancesof fireproofing, insulation and weatherproofing of the board are better improved, the expanded graphite is used as a foaming agent, the high temperature foaming process is used, the sectioned thermalinsulation mode is adopted in sintering, the hardness, the high temperature resistance and the flame retardance performance of the heat insulation board are improved, the density and the pore distribution of the board are better controlled, the better effects of heat insulation, light weight and high strength are achieved, and the heat insulation board further has the functional characteristics offireproofness, sound insulation, waterproofness, anti-aging, corrosion resistance, green and environmental protection.

Description

technical field [0001] The invention relates to the technical field of new building thermal insulation materials, in particular to a foamed lightweight thermal insulation board based on graphene and stone tailings and a preparation method thereof. Background technique [0002] my country's research on external wall insulation materials began in the early 1980s. After more than 20 years of development, the more commonly used insulation materials include the existing insulation boards such as extruded polystyrene board (XPS) and expanded polystyrene board (eps). ), polyurethane insulation board, phenolic insulation board, etc. [0003] Among them, the extruded polystyrene board (XPS) itself has high strength, which makes the board brittle and not easy to bend. The stress on the board is concentrated when the stress exists on the board, which is easy to damage and crack the board; if the temperature difference between the two sides of the board is large , high humidity is prone...
