Description
Technical field
The present invention relates to a kind of method for preparing lightweight wall plate using ceramic solid waste, belong to industrial solid castoff utilize with
Building energy conservation materials for wall field, and in particular to a kind of to utilize the solid wastes such as ceramic solid waste, flyash, discarded dregs, sludge
Object, again by being machined into a kind of lightweight wall plate with heat preservation, fire-proof function after high temperature sintering.
Background technique
Ceramic can generate a large amount of solid waste in production process, wherein most be cracking or deformation ceramic product,
Waste material and ceramic defect ware that work in-process generates etc..With increasing rapidly for ceramic yield, the solid waste of generation is increasingly
Increase.Currently, China's ceramic industry treatment of wastes produced is relatively low with utilization rate, a large amount of waste residues is caused to tie up arable land, pollution environment,
Limit the development of ceramic industry.Ceramic industry solid waste becomes the problem of society and business circles are paid close attention to jointly using oneself；
The flyash of coal power plant discharge, also belongs to solid waste, also has pollution to environment and water source；
Urbanization, the speed-raising of urbanization, the reconstruction of the old city town in shanty town constantly expand, and produce largely discarded dregs,
There is biggish pollution to environment and underground water source；
Sand(-)washing plant will generate a large amount of washed-out sand sludge in the process of sand, the sewage of industrial enterprise is produced by precipitating
The domestic sludge of raw industrial sludge, city domestic sewage treatment plant settlement of sewage generation, it is harmful to environment, it is necessary to carry out
Harmless treatment；
On the other hand, China uses most important thermal insulating material of the B2 grades of combustible material polyphenylene heat insulation slabs as building energy conservation
Material, it is cheap although its thermal insulation property is superior, it is easy for construction；But it is easy to that serious fire occurs: as Beijing is entreated
Depending on the wildfire occurred during the construction of exterior insulation system of new address 2009-02-03；The prosperous 2011-02-03 in Shenyang ten thousand is drawn due to fireworks
The wildfire built up and occurred using the skyscraper outer heat preservation system of many years risen；Shanghai Jiangzhou road 2010-11-15
Building exterior wall heat preserving decoration renovation during the wildfire etc. that occurs, be all caused by polyphenylene heat insulation slab.For these
Wildfire, relevant departments use series of improving measures, from heat preservation, fire proofing material to building heat preservation and architecture-integral.
Although country pays much attention to the fire safety problem of architectural design, new to have formulated " Code for fire protection design of buildings " GB 50016-2014；But
It is that by practice in recent years, or based on polyphenylene heat insulation slab, inorganic heat insulation material only accounts for few a part, few at this
In the inorganic heat insulation material of part, the mainly foam glass of rock wool, air-entrained concrete building block, foam concrete block and fritter
Deng, the lightweight wall plate of bulk cannot be formed, wall, but also substitution insulating layer have not only been substituted, and can be prevented fires, it is also durable.
How the solid waste such as ceramic solid waste, flyash, discarded dregs, sludge are fabricated to one kind has heat preservation, prevents
Fiery, durable lightweight wall plate, had both solved the problem of environmental pollution of above-mentioned solid waste, and it is energy-efficient also to solve energy saving building
Heat preservation, heat-insulated, the integrated wall problem of fire prevention, are the projects urgently studied.
The present invention attempts to carry out existing energy saving building insulating wall material technology innovation, substitution, designs a kind of utilization
Method of the solid waste such as the ceramic solid waste preparation with heat preservation, the lightweight wall plate of fire-proof function, had both solved ceramic solid waste, powder
The problem of environmental pollution of the solid waste such as coal ash, discarded dregs, sludge also solves the heat preservation, heat-insulated, anti-of energy saving building
The deficient problem of fiery integrated wall material, improves the thermal insulation property of wall, fire protecting performance, and endurance quality has accomplished thermal insulating material
Material and building same service life.
