Description
Technical field
The invention belongs to baking-free brick technology fields, and in particular to a kind of addition modified pearl rock-glass bead preparation heat preservation
The method of heat-insulated mixing tailing baking-free brick.
Background technique
Currently, the tailing quantity in stock in China is very big, and there are many type, these tailings not only pollution of ecological environment, wave
Take land resource, but also there are security risk, result in waste of resources.How to handle these tailings and also become one and needs to solve
Certainly the problem of, such as builds tailing dam and is stored up, for bashing, but the recycling of tailing is sharp using traditional method
Increasingly paid attention to direction, is favored wherein making non-burning brick direction using tailing.
Expanded and vitrified small ball is a kind of novel inorganic lightweight material, has light fire-proof, physicochemical property stabilization, water absorption rate
The low, excellent properties such as thermal coefficient is small, are widely used in building energy-saving heat-insulating material.But since expanded and vitrified small ball is transporting
With it is easily broken in forming process, cause its thermal insulation property to be deteriorated, water absorption rate the problems such as increasing substantially, to limit its application
Field, therefore how to carry out enhancing to it while keeping excellent characteristics possessed by expanded and vitrified small ball itself and be treated as
The widely applied key of expanded and vitrified small ball.
With the economic level in China and the continuous improvement of resident's living conditions, the functions such as insulation of building are constantly complete
It is kind, but while meeting the requirement of resident's comfort level, building energy consumption problem is also more prominent.China's existing building 95% is high consumption
It can build, architectural energy consumption reaches 33% or so of national total energy consumption, and the ratio that exterior wall energy consumption accounts for building energy consumption is maximum, therefore
The development of external wall energy-saving thermal insulation material and the application of technology will play the role of building energy conservation vital.
Phase-changing energy storage material, which has, adjusts the characteristics such as temperature, storage energy, and exterior-wall heat insulation has the performances such as heat preservation, heat-insulated, if
The two is combined, i.e., there is heat preservation, heat-insulated function using phase-changing energy storage material in the thermal insulation mortar of exterior wall, gypsum, coating
Can, while also there is the characteristic for adjusting temperature and storing energy, will there is important meaning to the whole energy consumption for substantially reducing building
Justice.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of addition modified pearl rock-glass bead preparation guarantor is provided
The method of the heat-insulated mixing tailing baking-free brick of temperature, the mixing tailing baking-free brick according to this method production have good heat insulation property
