Description
Technical Field
The invention belongs to the technical field of building materials, and particularly relates to a light inner wall capable of realizing heat preservation and sound insulation.
Background
At present, most of the interior wall panels applied to building engineering, particularly to high-rise buildings, are made of light materials. In the prior art, different sizing agents are used as surface layer materials and are pre-compounded with light heat-insulating core materials to form the light sandwich board. However, in the prior art, the inner wall and wall plates are generally made by bonding multilayer material plates by adhesives, but the bonding strength between the layers of materials is not ideal, and the phenomenon of delamination occurs after long-term use, which affects the service life of the inner wall and wall plates; moreover, the composite insulation board in the prior art has poor flame-retardant and fireproof performance and low safety performance.
Secondly, along with the improvement of living standard of people, higher requirements are also provided for the comfort level of living environment, and people not only pay more and more attention to the functionality of the interior decoration material, but also provide more requirements for the safety and environmental protection performance of the interior decoration material. However, most of the interior wall panel materials in the prior art do not have the safety and environmental protection performance, and cannot meet the needs of people.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides the light inner wall capable of realizing heat preservation and sound insulation, the light inner wall has excellent heat preservation and sound insulation effects and flame retardant effects, and has the advantages of high phase change heat utilization rate, light weight, high strength, convenience in use and the like.
In order to achieve the purpose, the invention adopts the following technical scheme:
the light inner wall capable of realizing heat preservation and sound insulation comprises a foamed glass honeycomb core layer and an outer protection material, wherein the outer protection material is poured on the foamed glass honeycomb core layer during machining, the outer protection material is poured into honeycomb holes of the foamed glass honeycomb core layer, and the foamed glass honeycomb core layer is integrally wrapped in the outer protection material.
Preferably, the foamed glass honeycomb core layer comprises the following components in parts by weight: 20-30 parts of high-titanium blast furnace slag, 8-15 parts of fly ash, 10-15 parts of ceramic fiber hollow glass particles, 2-6 parts of foaming agent and 2-6 parts of foam stabilizer.
The foam glass is also called porous glass or foam glass, and is heat-insulating glass with porosity above 90% and uniform pores. Because the pore structure of the material has the physical property of borosilicate, the material has the characteristics of air impermeability, no combustion, no deformation, no deterioration and the like when being used as a heat insulation material, and therefore, the material is widely used as an indoor and outdoor non-combustible heat insulation material. According to the foamed glass honeycomb core layer, TiO2 in the high-titanium blast furnace slag is used as a nucleating agent, so that the nucleation speed of glass crystallization is reduced, the foamed glass honeycomb core layer is well mixed with glass to form a large number of tiny crystal nuclei, and the foamed glass heat-insulating material with a stable porous structure is formed.
Preferably, the ceramic fiber glass particles are prepared by the following method:
(1) spraying a polyvinyl alcohol adhesive solution on the surface of the urea sphere, then coating ceramic fiber, drying, and sintering at high temperature to obtain a ceramic fiber hollow sphere;
(2) grinding waste glass into powder, and heating and melting to obtain a glass melt; adding ceramic fibers into the glass melt and uniformly mixing to obtain glass melt containing the ceramic fibers;
(3) and (3) adding the ceramic fiber hollow spheres obtained in the step (1) into the glass melt containing the ceramic fibers obtained in the step (2), uniformly mixing, obtaining glass spheres by a cooling method, and carrying out annealing and heat preservation treatment to obtain the ceramic fiber glass particles.
