Description
Technical field
The present invention relates to a kind of production methods of lightweight wall plate, belong to industrial solid castoff utilization, building energy conservation wall
Material Field, and in particular to it is a kind of to utilize industrial solid castoff, it is used again after high temperature sintering and is machined into a kind of tool
There is the lightweight wall plate of heat preservation, fire-proof function.
Background technique
With the development of mining industry, it is useless to belong to solid for the various mine tailings or CHARACTERISTICS OF TAILINGS SAND generated during mining activities
Gurry is deposited among mountains and rivers and river more, takes up an area and pollute environment, and some meetings generate great accident, to the life of the people
Property causes heavy losses；
Urbanization, urbanization, the reconstruction of the old city town in shanty town expand, and a large amount of building waste are produced, to environment and ground
There is biggish pollution at lower water source；
The flyash of coal power plant discharge, also belongs to solid waste, also has pollution to environment and water source；
The Waste foundry sand that foundary industry generates, and belongs to solid waste, to environment and and water source also have pollution,
Etc..
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, such as from heat preservation, fire proofing material to building heat preservation and building one
Change.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 by practice in recent years, or based on polyphenylene heat insulation slab, inorganic heat insulation material only accounts for few a part,
In this small part inorganic heat insulation material, the mainly foam of rock wool, air-entrained concrete building block, foam concrete block and fritter
Glass etc. cannot form the lightweight wall plate of bulk, not only substitute wall, but also substitution insulating layer, and can prevent fires, also durable.
How above-mentioned industrial solid castoff to be fabricated to a kind of with heat preservation, fire prevention, durable lightweight wall plate, both solved
It has determined the problem of environmental pollutions of various industrial solid castoffs, has also solved the heat preservation of building energy conservation, heat-insulated, fire prevention integration is asked
Topic realizes sustainable development, is the project urgently studied.
The present invention attempts to carry out existing energy saving building insulating wall material technology innovation, substitution, designs a kind of lightweight
The production method of wallboard, had both solved the problem of environmental pollution of various industrial solid castoffs, also solved the guarantor of energy saving building
Warm, heat-insulated, the integrated heat preservation of fire prevention, fire-proof wall problem of materials, improve the thermal insulation property of wall, fire protecting performance, durability
Can, accomplish thermal insulation material and building same service life.
