Description
Technical field
The invention belongs to technical field of material, and in particular to a kind of preparation method of foam glass.
Background technology
Building energy conservation is a national extremely important policy, be benefit the nation and the people, the system engineering for the offspring that benefits future generations.Add
The insulation of strong building is not only directly but also real for the work and housing conditions, energy saving role that improve people
Border, in China's building heat preservation insulation contractors, thermal insulation material water absorption rate is high, durability difference is always two hang-ups, it is greatly dropped
The heat-insulating property of low material influences the effect of insulation, increases the energy expenditure of air-conditioning system.And after absorbing water, insulating layer
Become aquifer, waterproof layer can be made to play drum and destroyed, cause to leak, still leak in a very long time after the rain.In exterior wall
In construction, due to the needs of insulation, wall need to be thickeied and use functional requirement to meet, due to there is no thermal insulation material at present
Original common brick can be replaced as materials for wall, outer patch thermal insulation material can only be used to carry out insulation.Outer wall heat insulating is main
There are three types of forms, the first is that polyurethane hard bubble thermal insulation material etc. is sprayed directly on wall, and heat insulation effect is preferable, but in sunlight
Easy to aging under irradiation, contraction and cracking, are not easy to construct, cost is higher；Second is using bonding modeling polystyrene board, it is main
Problem is that cost is too high, and every square metre at more than 150 yuan or more；The third is more using benzene plate, silk screen, mortar, powder and coating
It is waited up to six or seven layers and is staggeredly mixed to form insulating layer, adopted currently, setting up centralization in severe cold, cold district and hot-summer and cold-winter area
Warm newly-built, enlarging, reconstruction residential architecture (including house, apartment, villa, dormitory, hostel, ward room, nursery etc.)
Mostly this kind of form is used to carry out external wall body thermal insulation；Although it has preferable heat insulation effect, material price is cheap, is not easy to apply
Work, layer and layer are easy to fall off, crack, and fire line is also not very good, and construction efficiency is not high.And foam glass be one kind with waste plate glass
It is raw material with container glass, and add foaming agent, property-modifying additive and foamed promoter etc., then through the porous of high temperature foaming
The material of inorganic non-metallic material, generation has superior adiabatic (cold insulation), sound absorption, moisture-proof, fire prevention, waterproof, and nontoxic, corrosion resistant
Erosion, mothproof, not aging, "dead", insulation, anti-magnetic wave, antistatic, lightweight intensity is high, good etc. special with all kinds of mud caking property
Property.It is that a kind of performance is stable and can be widely applied to the multifunctional novels proximate matter such as external wall and roof insulation, sound insulation, waterproof
Material.Foam glass can apply to the heat insulating work of flue, kiln and freezer, various air-liquids, oily conveyance conduit it is heat-insulated, anti-
Water, FPE, subway, library, office building, theatre, movie theatre etc. be various need sound insulation, heat insulation device place, basis
The isolation of Facilities Construction, insulation works, the multiple fields such as rivers and canals, guardrail, the leakproof of dykes and dams, mothproof engineering.
