Graphene-based stone foamed lightweight wall plate and preparation method thereof

Abstract

The invention belongs to the field of building enclosure wall materials and in particular relates to a graphene-based stone foamed lightweight wall plate and a preparation method thereof. The stone foamed lightweight wall plate contains the following components in percentage by weight: 45-90% of stone tailings, 0.05-10% of a high-temperature cosolvent, 0.05-15% of graphene, 0.05-5% of expanded graphite, 1-20% of zirconia, 0.05-10% of calcium carbonate, 1-10% of clay, 0.05-5% of a stabilizer, 0.05-5% of a dispergator and 0.05-5% of inorganic colors. The stone foamed lightweight wall plate has the advantages of integrating overall performances such as obvious aging resistance, corrosion resistance, heat insulation, sound insulation, water seepage resistance, fire resistance, lightweight, high strength, cracking resistance, greening and environment friendliness, the preparation method is simple and easy to operate, and the production process is green, low-carbon, high-efficiency, energy-saving and consumption-reducing.

Description

【Technical field】 [0001] The invention relates to the field of building enclosure wall materials, in particular to a foamed lightweight wallboard based on graphene and stone and a preparation method thereof. 【Background technique】 [0002] The existing concrete aerated blocks, shale hollow bricks, lightweight ceramsite concrete wall panels, and lightweight polyethylene concrete wall panels are of poor quality for the interior and exterior walls of the same volume, low compressive and flexural strength, and sound and heat insulation. Poor performance, poor waterproof and impermeability, high water absorption, easy cracking at joints, easy cracking and falling off of cement mortar batch layer, easy aging, unsafe and environmentally friendly, when making partition walls with aerated concrete and hollow brick wall panels, there are Large volume, large building space, heavy weight, sporadic masonry is required, the surface of the wall panels needs to be leveled with cement mortar...

The invention with the Chinese patent application number 201610090524.3 discloses a cement-based foamed lightweight composite material and its preparation method. Regulation, through the use of modified starch foam stabilizer and graphene oxide nano-materials to achieve effective regulation of the pore structure and cement hydration products and structure, so that the pore structure formed has fine particle size, uniform distribution, and regular shape of cement hydration products , arranged in an orderly manner, so that the cement-based foam composite material has a cross-linked network structure, so as to improve the strength and toughness of the cement-based lightweight composite material, but the raw materials used need to be pre-treated, and the operation process is complicated, only recorded The density in strength is 0.6~0.7g / cm 3 , the compressive strength is greater than 2.5MPa, and the wear resistance, weather resistance, high temperature resistance, heat insulation, sound insulation, waterproof and impermeability have not been better improved, and need to be improved

The invention of Chinese patent application number 201610258377.6 discloses a lightweight partition wall board with loofah fibers added. In this application, a large amount of chemical additives and conventional raw materials are used. The raw materials are expensive and complicated. The prepared wall board has good Excellent heat insulation effect, not prone to gaps, moisture absorption, and bubbling characteristics, which improves the quality of the partition wall, but the water absorption rate still reaches 21.4%, and the compressive strength is 5.5MPa, and there is still room for further improvement
