Abstract
The invention provides a novel thermal-insulation building block, which belongs to the field of building materials. The novel thermal-insulation building block has a heat conductivity coefficient of 0.08 W/(m.k) and comprises the following raw materials by mass: 54 to 58% of fly ash, 14 to 18% of vitrified microsphere, 5 to 6% of cement, 19 to 21% of quicklime, 2 to 3% of gypsum and 0.05% of aluminum powder. A wall built by using the building block has self-heat-preserving performance and can perform a thermal-insulation effect meeting requirements prescribed in national energy saving standards in China without secondary thermal-insulation subdivisional construction. The wall has the advantages of a substantial thermal-insulation effect, no need for construction of other thermal-insulation system, reduction in a construction period for a building, decrease of cost and conservation of cost.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of New Insulation Building Block.
Background technology
At present, China's building energy conservation body of wall is taking external wall outer insulation as main, main external insulation system has: expansion polyphenyl plate external insulation system, large die built-in polyphenyl board external insulation system and glue powder polyphenyl particle external insulation system etc., its common ground is all at peripheral structure one deck polystyrene foamed material that bonds outward.
There are three large disadvantages in the practice of these several external insulation systems: one, and polystyrene belongs to petroleum product, can aggravate energy shortage, its two, affected by oil price, construction costs fluctuation is large, price is high, they are three years old, the weather resistance (comprising resistivity against fire) of heat insulation system has been subject to query. and New Insulation Building Block is that one has realized resource, the novel wall material of Performance and Cost Modeling best of breed, have energy-conservation, comprehensive utilization of resources, the plurality of advantages such as recycle, wherein the most outstanding advantage is that energy-conservation this building block can meet the requirement to wall heat transfer coefficient in 65% energy conservation standard, and the heat insulation system of this building block composition is non-petroleum product, endurance quality (comprising resistivity against fire) is indubitable, in as cladding, play again the effect of insulation, comprehensive cost is starkly lower than above several heat insulation systems, so be the optimal selection of wall heat insulation material., the application prospect of New Insulation Building Block is very wide, to promoting the technical progress of outer wall heat preservation system also very favourable, the development that promotes building block industry is had to active effect.
Summary of the invention
Dangerous large in order to overcome exterior-wall heat insulation construction, material fire-protection rating is not high, and the shortcoming of long construction period the invention provides a kind of New Insulation Building Block, thereby shortens engineering, reduces construction costs, cost-saving, energy-saving and emission-reduction.
Technical scheme of the present invention is:
Raw material is by mass percentage: flyash 54～58%; Glass bead 14～18%; Cement 5～6; Unslaked lime 19～21%; Gypsum 2～3%; Aluminium powder 0.05%, water.
Wherein, water is 0.53～0.58 of above-mentioned raw materials gross weight.
Above-mentioned raw materials is mixed through increasing temperature and pressure 3h, constant temperature and pressure 5h(200 DEG C, 1.5MPa), decrease temperature and pressure 2h, finally go out still.The thermal conductivity of the New Insulation Building Block of making is 0.08W/ (mk); And meet national sector standard JG/T407-2013.
The body of wall that the present invention builds by laying bricks or stones has self-insurance warm nature, and the construction that does not need to carry out again secondary insulation subitem just can reach the heat insulation effect of national energy-saving standard-required; Wall thermal insulating effect is remarkable, without other heat insulation system constructions, shortens the building operation duration, reduces cost, cost-saving.
Embodiment
Proportioning raw materials (mass percent): flyash 56.95%; Glass bead 16%; Cement 5; Unslaked lime 20%; Gypsum 2%; Aluminium powder 0.05%, water is 0.53～0.58 of material.
Above-mentioned raw materials is mixed through increasing temperature and pressure 3h, constant temperature and pressure 5h(200 DEG C, 1.5MPa), decrease temperature and pressure 2h, finally go out still.
