Abstract

The thermal insulating brick in the shape of rectangle, square or arc is made up of such raw materials (wt.%) as flyash (55-88), expanded pearlite (25-35), used polystyrene foam particles (3-10), and cement (5-15) through proportional mixing, addition of appropriate water, stirring and moulding under 7-10 kg pressure, and features good insulating performance and light weight.

Description

Thermal insulating brick and making method thereof
The present invention relates to a kind of insulating brick, belong to the thermal isolation technique field, be applicable to the insulation of buildingss such as pipeline, kiln, equipment and roof.
Traditional lagging material such as asbestos, vermiculite, diatomite, perlite, mineral wool and goods thereof, its shortcoming are that density is big, the thermal conductivity height, and construction is inconvenient.Application number is 92102051 inorganic composite insulating material, and adopting flyash and pearlstone is aggregate, and sepiolite, asbestos, wilkinite are the mashed prod that filler and water, tackiness agent, permeate agent combine.Its shortcoming is the slurry construction, and is dry slow, long construction period.
The objective of the invention is to overcome the weak point in the above-mentioned background technology, and a kind of good heat insulating is provided, body is light, easy construction, insulating brick of short construction period and preparation method thereof.
The object of the present invention is achieved like this: this invention be shaped as the square or lonely shape brick of rectangle, its material composition is (weight ratio): flyash 50～58%, pearlstone 25～35%, waste polystyrene foam plastic particle 3～10%, cement 5～15%.Its making method is: with flyash, pearlstone, waste polystyrene foam plastic particle, after cement mixes in proportion, add the water of overall weight 18～20%, put into mould, get product at 7～10 kilograms forming under the pressure.Pearlstone wherein, the waste polystyrene foam plastic particle can reduce thermal conductivity and density, contains a large amount of microballons in the flyash, and not only thermal conductivity is low, and density is relatively also less.Cement had both played cohesive action, also can improve product strength.
Purpose of the present invention can also reach by following measure:
The best proportioning (weight ratio) of its material composition is: flyash 55%, pearlstone 30%, waste polystyrene foam plastic particle 5%, cement 10%.
The present invention compares with background technology has following advantage:
1, waste polystyrene foam plastic particle and flyash all are utilization of waste material, can turn waste into wealth, and reduce the pollution to environment.
2, body is light: density is 350～400kg/m 3
3, good heat insulating: thermal conductivity is 0.06～0.07W/mk.
4, compressive property is good: ultimate compression strength is 0.4MPa/cm 2More than, watt better than perlite.
5, cost is low, and price is low, than perlite watt low about 20%.
6, because of being formed material, short construction period has overcome slurry lagging material drying slowly, the shortcoming of long construction period.
The invention will be further described below in conjunction with (accompanying drawing) embodiment:
Accompanying drawing is a structural representation of the present invention.
Embodiment: get 55 kilograms in flyash, 30 kilograms of pearlstones, 5 kilograms of waste old polystyrene foamed plastic particles, 10 kilograms of cement add 18 kilograms water, fully stir, it is mixed, put into mould, moulding promptly gets finished product of the present invention in 10 kilograms of pressing machinees.

Claims (3)

1, a kind of insulating brick is characterized in that: it is shaped as the square or lonely shape brick of rectangle, and its material composition is (weight ratio): flyash 50～58%, pearlstone 25～35%, waste polystyrene foam plastic particle 3～10%, cement 5～15%.
2, according to claim, described insulating brick is characterized in that: the best proportioning (weight ratio) of its material composition is: flyash 55%, pearlstone 30%, waste polystyrene foam plastic particle 5%, cement 10%.
3, the making method of insulating brick as claimed in claim 1 is characterized in that: get flyash, pearlstone, waste polystyrene foam plastic particle and cement, by said ratio, after mixing, the water that adds overall weight 18～20%, be placed in the mould, get product at 7～10 kilograms forming under the pressure.
