Description
Technical field
The present invention relates to a kind of self-heat conserving foamed ceramics composite wall body material, particularly relate to a kind of glaze self-heat conserving foamed ceramics composite wall body material and preparation method thereof.
Background technology
Slag is the industrial waste of Steel Plant, and the slag amount that produces in steelmaking process is about the 15%-20% of output of steel.With 2008 be example, Chinese output of steel is about 5.0 hundred million tons, slag promptly reaches nearly hundred million tons.And the utilization ratio of slag is lower, and as slag is all abandoned as industrial waste, floor space is very big, takes up an area of in order to reduce waste residue, prevents the pollution of the environment, and iron and steel enterprise is just making great efforts to explore the Multipurpose Utilization of Steel Slag approach in recent years, in the hope of turning waste into wealth.
Flyash is the waste of coal-fired thermal power factory discharging, in recent years, along with developing rapidly of power industry, the flyash quantity discharged sharply increases, and the flyash total amount that coal-fired thermal power factory is discharged every year increases year by year, is about 1.5 hundred million tons in 2000, to reach 300,000,000 tons by 2010, how to realize the comprehensive utilization of flyash, turn waste into wealth, turn bane into boon, become the problem that people constantly explore.At present, flyash can be used widely in all departments such as building worker, building materials, water conservancy.
The up-to-dateness of China's building operation is lower, and basic reason is intensity, heat-insulating property and the aesthetic property that material of construction will reach country and user's requirement, needs to divide materials for wall, lagging material, finishing material is successively constructed, it is loaded down with trivial details to construct, and the cycle is very long, and security is also very poor.Compoundization building materials more and more are subject to people's attention.
Present most widely used materials for wall is pressed the difference of thermal insulation layer material, mainly is divided into external heat insulating wall system, inside heat insulation wall body system and self heat insulation wall system.Self heat insulation wall self-heat conserving system wherein, adopting collection to go along with sb. to guard him with incubation and thermal insulation function is the light wall material of one, can effectively solve outer wall cracking, the caducous problem of exterior wall tile, can prolong the wall body structure life-span; Maintenance cost is low, and is safe and reliable, and outer decoration can be diversified; Owing to need not save inside and outside compound thermal-insulation system material and construction, under the prerequisite that reaches identical energy-saving and thermal insulating effect, have the good technical economic benefit at the nonweight-bearing heat insulating tectonic system of the inside and outside increase of main body walling.In Department of Science and Technology's Eleventh Five-Year Plan supporting plan project, also comprise the energy-saving residence self-heat preservation heat insulation wall, this shows that energy-conservation self heat insulation wall has become one of China's building technology field development priority.
Foamed ceramics is a kind of ceramic of three-dimensional cubic network skeleton structure.It is evenly distributed and has the micropore of mutual perforation, thereby have that density is little, void content is higher, specific surface area is big, low-thermal conductivity, advantage such as high temperature resistant, corrosion-resistant, be widely used in thermal and sound insulating materials, industrial sewage processing, vehicle exhaust processing, electrotechnical, electronic field, field of medical materials and biochemical field.On performance, foamed ceramics is well suited for as material of construction, realizes the insulation of building, heat insulation, sound insulation, fire prevention, antidetonation, prolongs life, can be used as the main part of non-bearing composite wall body material, plays dual parts to be incubated and to go along with sb. to guard him.At present, prepare the research that foamed ceramics is used for materials for wall with slag and do not see bibliographical information as yet.
