Abstract

A color curb is composed of a main body made of ordinary concrete and a color surface layer. It is made up by a special mould composed of internal and external plastic moulds through pouring color material into the gap between internal and external moulds, vibration, then laying aside, removing internal mould, pouring concrete, vibration, levelling, then laying aside for 72 hr, demoulding, and curing for 3 days. Its advantages are high strength, color fastness, antiwear performance, smooth finish and size precision.

Description

Coloured curb and particular manufacturing craft and manufacture method

Technical field

The present invention is in International Classification of Patents, relate to building or its paving of road, stadium or similar engineering: build the machinery and the outfit group (E01C) of repairing usefulness, also with clay or other ceramic component, slag or to contain the mixture group (B28B) of cement material relevant, coloured curb and particular manufacturing craft and the manufacture method continued to use of road both sides or flower bed circle particularly.

Background technology

Common curb is that common building stones cut cutter or stir injection molding by cement, stone, sand and water and form.Product colour is gloomy, rough surface.99222179.X number patent and No. 00229822.8 patent provide the coloured curb technology for society, have played good facilitation to beautifying the environment, warn traffic.99108287.7 the manufacture method that discloses coloured curb that number patent application is then comparatively detailed.This method forms the colored front surface and the upper surface of curb step by step.Analyze from text, this method demoulding difficulty has the disadvantage of scurrying material between colored surface layer and the basic unit.

By the new scape in Zhejiang Jiaxing city industrial corporation is No. 98124500.5 the innovation and creation that present bright and beautiful magnificent Industrial Co., Ltd. provides, and discloses colour floor brick and preparation method thereof.Its colored surface layer has adopted and has been cement by weight: sand: water: water reducer: pigment=1: 0.8-1.8: 0.26: 0.01～0.09: 0.004～0.15 prescription.Said water reducer chemical general formula is: Said pigment is that metal oxide, titanium cyanines are green, and for example iron oxide yellow, iron oxide red, chromium peroxide, titanium dioxide etc. are selected materials according to required color.The floor tile that this method is produced, its surface layer intensity height, color fastness, wearability, fineness are all more satisfactory.

The invention scheme

The purpose of this invention is to provide a kind of coloured curb and particular manufacturing craft and manufacture method.

It is as follows to disclose new technical scheme;

A kind of coloured curb is made of the basic unit and the colored surface layer of normal concrete.The colour plane layer material is cement by weight ratio: sand and/or stone: water: water reducer: pigment=1: 1～1.5: 0.20～0.22: 0.03～0.07: 0.004～0.1.Particular manufacturing craft is tiltedly to put corresponding with the coloured curb profile and inverted external mold on the mould bases, and internal mold places the bottom of external mold and the gap that maintenance is equivalent to the colour plane layer thickness.The preparation method of coloured curb is to put into the colour plane layered material in the gap between internal mold and external mold, vibrates 2-5 minute, leaves standstill 15-120 minute; Remove internal mold, cover steel plate or plank, add the normal concrete base material, on shake table, wipeed after vibration off 2-5 minute; Leave standstill the demoulding after 72 hours, and maintenance 3 days.

The coloured curb of Zhi Zaoing has the intensity height according to the method described above, advantage such as color fastness, wearability, surface smoothness are good.After particularly adopting special-purpose plastic form, the demoulding is easy, and surface-brightening is bright in luster, and the dimensional accuracy height, considerably beyond existing procucts.Can also improve output simultaneously, reduce cost.

The specific embodiment

On the mould bases 4 of metal or wooden making, tiltedly putting corresponding with the coloured curb profile and inverted external mold 1, internal mold 2 places the bottom of external mold 1 and the gap 5 that maintenance is equivalent to the colour plane layer thickness.Said colored surface layer is preferably upper surface and front surface, and front surface to curb and road surface intersection or intersection slightly down till.The hypotenuse of triangle mould bases 4 and horizontal plane have an angle, and be changeable, and angle is 45 ° usually.It has guaranteed that external mold 1 and horizontal plane keep identical angle, for example above-mentioned 45 °.Interior

external mold

2,1, favourable to the demoulding and the surface smoothness of curb when adopting plastic form, dimensional accuracy surpasses the metal formwork.

Coloured curb is made of the basic unit and the colored surface layer of normal concrete.The material of colored surface layer adopts proportioning in the background technology, and optimum ratio is cement by weight: sand and/or stone: water: water reducer=1: 1～1.5: 0.20～0.22: 0.03～0.07: 0.004～0.1.Said pigment is that metal oxide is good.Main aerobic iron oxide yellow, iron oxide red, chromium peroxide, titanium cyanines are green, titanium dioxide or the like, decide on the color of customer requirements.Usually choosing is yellow or white, does not also get rid of other colors.

Earlier the cement in the said components, pigment, sand and/or stone are stirred evenly, it is mixed to add water then, adds water reducer again and stirs 2 minutes to 1 hour, makes the colour plane layered material.Gap 5 with between colour plane layered material injection internal mold 2 and the external mold 1 vibrates 2-5 minute, places 15 minutes to 120 minutes.Time length is decided on the workshop temperature, when temperature is hanged down, adopts 120 minutes, to prevent the material of front surface and upper surface, flows to its intersection and long-pending thick.Remove internal mold 2, cover steel plate or plank, add normal concrete basic unit material, on shake table, wipe vibration 2-5 minute off.The demoulding after 72 hours, maintenance 3 days.When surface thickness 5 millimeter of coloured curb, this floor adopted more than No. 325 cement, intensity was higher.

Embodiment 1, and the siccative after 50kg425 white cement, 4kg iron oxide yellow are stirred evenly is put into machine with 60kg sand and/or stone and fully stirred.Add 12kg water then and stir, add the 2.5kg water reducer again, stirred 10 minutes.Put into the gap 5 of mould, vibrate 2 minutes, left standstill 35 minutes.After removing internal mold 2, cover steel plate or plank, will be by ordinary cement: yellow ground: basic unit's material of stone=with suitable quantity of water fully stir at 1: 2: 3, add external mold 1, wipe off and shake flat, 72 hours rear demouldings, maintenance 3 days becomes yellow curb.

Embodiment 2, mix into No. 425 white cement 50kg, titanium dioxides thoroughly siccative for 0.4～1 kilogram, put into sand and/or stone 60kg, fully stir.Add entry 12kg then and stir, add water reducer 2.5kg again, stir and became white capstock in 10 minutes.Again this material is put in the die clearance 5, stirred 2 minutes, leave standstill 40 minutes,, prolong dozens of minutes again if the workshop temperature is lower.After removing internal mold 2, cover steel plate or plank, put into basic unit's material, vibration on shake table, strickling.The demoulding after 72 hours, maintenance 3 days, white curb.

Embodiment 3, make above-mentioned pigment into iron oxide red 3kg, mix stirring into siccative with No. 425 normal silicates or portland slag cement, and all the other parameters and method are constant.Red curb.
