Abstract
The production method of multifunctional concrete block includes the following steps: firstly, pouring decorative layer on the bottom portion of the mould, in the formula of the decorative layer the nano titanium dioxide or other nano particles are contained, then pouring a layer of concrete, making vibration or applying pressure to make it be compacted, then placing filling material as heat-insulating material into the mould, then pouring concrete into gap portion of the mould, utilizing vibration or pressurizing equipment to compact them, and forming, curing and demoulding.
Description
The present invention relates to the production method of the multifunctional concrete decorative block that uses in a kind of architectural engineering.
At present the decorative buiding block of concrete that uses in the architectural engineering is by the block machine disposal pressed moulding, rough surface, and decorative effect is relatively poor, does not have antibiosis and self-cleaning and a self light emission function.
The purpose of this invention is to provide a kind of photocatalysis that has, antibiosis and self-cleaning is arranged and absorb the concrete decorative block of waste gas or light-accumulated luminous function.
To achieve these goals, the present invention is earlier at mold bottom cast one deck decorative layer, raw material are nanoparticles such as water, chemical industry auxiliary material, cement, filler, pigment, nano titanium oxide in the decorative layer prescription, mix and stir well even back injection molding, placed about 1 hour behind the vibratory compaction, cast concrete in mould again, the filler that has added function of heat insulation through vibration or pressurization after making it closely knit in the above, again at mould gap cast concrete, the vibration or the pressurization make it closely knit, after the maintenance demoulding product.
In the decorative layer prescription, nano titanium oxide changed into luminescent material when producing luminous concrete segment or add luminescent material and nanoparticle simultaneously.
Nano material in the decorative layer prescription can adopt multiple, as nano titanium oxide, receive silica, nano-aluminium oxide, nano-sized iron oxide etc.The mixture that can add a kind of nanoparticle or several nanoparticles during interpolation.
In addition, can adopt way to obtain the self-cleaning building block of multifunctional antibiotic at common decorative block surface preparation one deck nano thin-film.
Utilize the present invention to produce multifunctional building block, make building block have antibiosis and self-cleaning, multiple function such as light-accumulated luminous is improved block surfaces intensity, weather resisteant etc., can reduce environmental pollution, improves the decoration function of concrete segment.
Fig. 1 is the cutaway view after pouring into a mould decorative layer at mold bottom and making it closely knit.
Fig. 2 is the cutaway view after pouring into a mould the ground floor concrete and making it closely knit.
Fig. 3 is the cutaway view behind the adding filler.
Fig. 4 is at mould gap cast concrete and the cutaway view after making it closely knit.
Shown in Figure 1, earlier at mold bottom cast decorative layer 1.Mould uses mould of plastics.Formula for raw stock is a white cement in the decorative layer: quartz sand: brightener: pigment: nano titanium oxide=1: 1-1.5: 0.02-0.03: 0.01-0.03: 0.01-0.05, and add water stir in right amount the back injection molding.Injection molding thickness is 2-5mm, is placed on vibratory compaction on the shake table then, discharges bubble, under normal temperature laboratory, placed about 1 hour, and time in winter proper extension, the time in summer suitably shortens.Observe its surface and touch its hardness, to be difficult for squishing into suitable with finger with hand.
The layer concrete 2 of in mould, pouring into a mould shown in Figure 2.Concrete strength is placed on vibratory compaction on the shake table then by the relevant concrete hollow block standard preparation of country.Notice during cast that concrete thickness should be behind vibratory compaction and the wall thickness basically identical (30mm) of normal concrete building block.
Shown in Figure 3, in mould, put into filler 3 and 4, filler is selected the GPPS foamed plastics for use.In advance foamed plastics is processed into shape and the volume the same with normal concrete building block hole, and reins in reinforcing bar 5 and 6 with two bands and connect.Measure between them and they and the mould distance of wall all around with ocular estimate, adjust this distance and make this apart from the wall thickness of ordinary concrete hollow block, rein in thick basically identical.
Shown in Figure 4, live foamed plastics with hand, and to mould internal pore part cast concrete 7.With the mould gap water fill with and exceed mould a little, be placed on jolt ramming on the shake table then, the surface is floating.As mould after the jolt ramming less than, should add concrete and jolt ramming is floating once more again.The demoulding after natural curing 3-4 days under normal temperature laboratory, the sale of just can dispatching from the factory in natural curing 7-8 days under normal temperature laboratory after the demoulding.
The mould that should will pour decorative layer when adopting the insert mode of production earlier with positioner is fixed on vibration or the pressurized equipment, to put into mould with the insert of the same shape of normal concrete building block hole by positioner then, insert is used steel weldering system and is processed.Cast concrete in mould is filled with mould then, makes it closely knit with mode of vibration.Promote positioner then and make insert leave mould, in mould, just form like this with normal concrete building block two holes of a size.In hole,, these two holes are filled up GPPS foam-plastic blocks (with obtaining after the discarded foamed plastics pulverizing).Cast concrete again in the mould then, and exceed mould a little, adopt vibration or pressurized equipment to make its closely knit moulding, the demoulding after natural curing 3-4 days under normal temperature laboratory, under normal temperature laboratory natural curing 7-8 days again, the sale of just can dispatching from the factory.
Equipment can adopt the control of electronics, computer mode in process of production, makes it in batching, the time of pressurization, and strength control, what of inventory, the automatic adding of material reaches more accurate, realizes automated production.
When producing the luminous ornament building block, the decorative layer prescription should be white cement: quartz sand: brightener: pigment: luminescent material=1: 1-1.5: 0.02-0.03: 0.01-0.03: 0.01-0.1, prescription can be adjusted according to actual conditions, and an amount of nanoparticle can be added.
Block surfaces after the demoulding prepare one deck receive the material film have many methods to make.As liquid phase deposition, sol-gel process, chemical vapour deposition technique, thermal decomposition method, magnetron sputtering method etc.
When building block is prepared nano thin-film with sol-gel process, take by weighing a certain amount of metatitanic acid fourth fat, it is dissolved in the absolute ethyl alcohol, add acetylacetone,2,4-pentanedione again.Stir and add the mixed liquor of nitric acid and deionized water and absolute ethyl alcohol.More than the quantity of several materials than for metatitanic acid fourth fat: ethanol: water: nitric acid, acetylacetone,2,4-pentanedione=1: 18: 2: 0.02: 0.5.
The colloidal sol that the building block that utilizes equipment to clean is then prepared above putting into, speed with 1.5-2mm/s upwards proposes liquid level, and put into baking oven and be warmed to 450 ℃, make if desired that film is thicker to need to repeat above operation, building block is promoted from colloidal sol and oven dry repeatedly.
