Description

Light and heat insulating wall bricks

The invention belongs to building wall block, particularly a kind of light and heat insulating wall bricks that is used for the building construction body of wall.

At present, building trade mainly adopts wall brick and some constructional materials as the inner, external wall materials for wall of (also comprising partition wall, balcony dividing plate, roof panel etc.).Some is heavier for these materials, installs inconvenient; Poor performance such as some insulation, heat insulation, sound insulation, protection against the tide.For example, construction wall all is that the common brick that adopts clay to fire is built by laying bricks or stones for a long time, in the specific period or the warm area of southern climates popularize very much and practical.But the area for China's northeast weather cold then comes with some shortcomings.Along with the progress of society, the economic constantly development of science and technology the heat-insulating property of construction wall and warming is saved being considered to of aspect such as heat energy and attached most importance to, so people has proposed the requirement of each side such as energy-saving and environmental protection, insulation to body of wall.Current searching replaces common brick, the materials for wall that on quality and price, is better than common brick, particularly nation-building portion proposes will reach energy-conservation 50% requirement to wall thermal insulating, make to save the energy and improve the building thermal technique condition and become pressing for of builing industry and even entire society, the foamed brick and the various combined wall technology such as (deck add heat insulation layer structure) of traditional common brick have appearred replacing in succession, as interior, external heat insulating wall, hollow concrete block wall, air-entrained concrete building block body of wall etc., these bodies of wall cut both ways, all there is the cost height, heat insulation effect is poor, floor space is big, and intensity is low, the big deficiency that waits of difficulty of construction.Chinese patent CN99124629.2 number a kind of light and heat insulating wall bricks is disclosed in the recent period, this technology comprises cement, flyash, water, be characterized in: it also comprises the polyethylene foamed particle, by volume part is compared, cement 1-1.25, flyash 2-6, water is an amount of, and the composition of polyethylene foamed particle 3-4.5 is formed.It can use cement, and flyash contains polyethylene foamed and becomes to be cellular, can also have good heat-insulating property at placement perlite in building block hollow, and in light weight than the existing lightweight walling unit of equal volume.And the hollow of this building block is vertical cylindrical hole, and its built-in perlite is though also improved heat-insulating property to a certain extent, but the gap between the cylindrical hole of its uniform setting then is provided with perlite, therefore its heat-insulating property is not high yet, and intensity is lower, and construction is inconvenient.

The objective of the invention is: improve at the problem that prior art exists, design provides a kind of reasonable in design, and warm domestic and international wall thermal insulation technology is in conjunction with the domestic construction characteristics, adopt raw material such as cheap flyash and macromolecule resin, all directions all have grout groove around the reasonable in design, building block, anti-carrying, Wind-Pressure Resistance, antiseismic, quality is light, and floor space is little, heat-insulating property is higher, solved the empty distension of surface layer, split and cold bridge etc., speed of application is fast, the quality height, save mortar, reduce labour intensity, construction adaptability is strong, the light and heat insulating wall bricks of good stability.

The present invention is achieved by following manner: a kind of light and heat insulating wall bricks, it is characterized in that this block body (9) is designed to " S " type, as shown in Figure 1, is provided with respectively and block body (9) is reinforcement interlayer (3) and (11) of one in the upper right of " S " of this block body (9) type and lower-left opening part horizontal length direction (normally 1/3rd positions), and block body (9) is separated into insulation enclosed cavity (2) and go up insulation atrium (5) and down insulation enclosed cavity (8) and under insulation atrium (12), here go up insulation enclosed cavity (2) and go up insulation atrium (5) and down insulation enclosed cavity (8) and under insulation atrium (12) be to be staggered, and when building by laying bricks or stones, after last building block is put well, the vertical Rotate 180 degree of back one building block, insulation atrium (5) is connected into an insulation enclosed cavity identical with following insulation enclosed cavity (8) size with last insulation enclosed cavity (2) just with following insulation atrium (12) on this moment, can place various heat insulating materials in these insulation enclosed cavities (as polystyrene or title benzene plate, phenolic board, polyamine fat plate etc.), with bottom right sealing place recessed block mouthful (14) and vertical grout groove (15) and protruding block mouth (6) and the vertical grout groove (7) thereof that can cooperatively interact and build by laying bricks or stones is set respectively in that " S " of this block body (9) type is upper left, correspondingly with strengthening the grout groove (1) that is interconnected is set respectively on the interlayer (3) and (11) up and down in " S " of block body (9) type, (13), (16) and (4), (10), shown in Fig. 1-4.

The raw material of the present invention and the technological process of production are:

One, material and formation mechanism:

1, main raw material(s): A, fly ash in electric power plant; B, automation type aqueous epoxy resins; C, enhanced fiber; D, form modifier by alkaline constituents and sulfate; E, the aggregate of forming by brick and tile, sand, stone (particulate).

2, concrete material analysis:

Flyash is the industrial residue of steam power station discharging, will discharge 200,000,000 tons flyash and coal drystone every year, owing to have a large capacity and a wide range, and serious environment pollution and take a large amount of soils, for a long time, the comprehensive utilization of flyash is all attached great importance in countries in the world.China does not still catch up with the discharge value of power plant to the comprehensive utilization of flyash, and only 3,000 ten thousand tons of year utilizations, remaining a large amount of appropriation of land, severe contamination a part of rivers, lake and town and country atmospheric environment, therefore the development and use of flyash, resource is wide, price is low, solves environment pollution and soil utilization, and country has put into effect the value-added tax from implementation on the 1st in January calendar year 2001 for this reason, promptly increase the collection policy of promptly moving back and reducing by half, promoted the development and use of flyash greatly.

Resin concrete (pc) was used widely in industry such as the building of developed country, electric, mechanical, chemical industry as far back as the seventies in 20th century, synthetic resin adds an amount of curing compound, flexibilizer, thinner and filler as bonding adhesive, with husky, masonry is aggregate, a kind of composite material that forms through mixing, moulding, curing.Shortcomings such as to have remedied concrete tensile strength low owing to have good anti-corrosion, wear-resisting, water-fast and anti-freezing property etc., and tensile atrain is little, crack resistance is little, fragility is big.Epoxy resin concrete after the curing all has very strong resistance to atmosphere, humidity, chemical mediator, bacterium etc.

This high performance organic-inorganic composite system of resin-mortar, improved the building block crosslink density, improve freeze thawing and resisted mixing property process to be, by flyash and material modified modified particles has bigger inner surface and hole under the mix forcing, water infiltrates in the hole, be dispersed in the fly ash grain body at generation Ca (HO) and gradually become the plasticity powder, form the powder oar, add water-soluble resin when shearing is mixing, polycondensation takes place in the water soluble resin monomer under the high speed shear solidification, produce reaction,, quicken to generate Ca (HO) the fly ash grain parcel, discharge unnecessary moisture content, increase for the powder that does not have complete mix and regulate, form complete plastic, further aquation of fly ash grain and interlaminar resin form a fine and close structure after extrusion forming.Simultaneously be transformed into oil phase by water, unnecessary moisture content evaporates by in resting.Form the complex of organic-inorganic.

Two, the technological process of production:

The technological process of production of present technique (perhaps being called the sandwich building block of solid energy) is that various raw and auxiliary materials are tied material (flyash, modifier) mouthful Admixture mouth resin according to (sand, microlith, the rock ballast) chewing-gum that gathers materials, and renders to the pressing machine that shakes through after 1-3 minute the stirring.After making product, place fog room, carry out insulation in 16-20 hour, resting is finished product, and fortune is put after outdoor 28 days and can externally be sold.

For fear of the excessive product quality that influences of aggregate size, or cause the damage of building block mould, gathering materials must be through the screening preliminary treatment.
