Abstract
The present invention discloses a wall plate made from steel fiber reinforced cement and a making method thereof. The existing walling materials have the defects of heavy weight, high price, toxicity(some walling materials), etc. In the making method, chopped steel fiber reinforced cement is used to make wall plate materials, and reasonable components of regular cement, inorganic light materials, steel fibers, coagulation accelerators, etc. are treated by the procedures of stir, pump extrusion, forming, water absorption, core pull, etc. to obtain the wall plate with light weight, energy conservation and high strength.
Description
The present invention is wallboard of a kind of steel fibre enhancing ordinary Portland cement and preparation method thereof.
Traditional materials for wall loam brick is commonly called as Qin brick and Han tile, and the history in existing several thousand, but loam brick Heavy Weight are not only made time-consumingly, and it is serious to ruin the field.In recent years, some novel materials for walls have appearred both at home and abroad, as thorough of concrete, thorough of gypsum, sheet asbestos, the Taibo plate is known uncle's plate etc., but these materials exist significantly not enough, as, weight is big, costs an arm and a leg, some material has toxicity such as carcinogenic, and some material temperature has toxic gas when higher and overflows.The wall board material that strengthens as glass fiber is owing to be method and the cutting injection method that adopts artificial lapping in addition, and automaticity is low, and labour intensity is big, and price is not cheap yet.The WO93/23343 patent disclosure a kind of steel fiber reinforced concrete material of high-flexural strength, but it only is suitable for beam for building, bridge floor or tunnel Dong Ding, and does not consider its deadweight, energy-conservation, sound insulation and processing technology.
The objective of the invention is to seek a kind of in light weight, low price, good energy-conserving effect, cement wall plate easy to make and preparation method thereof.
Wallboard of the present invention is the wallboard that strengthens ordinary Portland cement with steel fibre, and wherein Main Ingredients and Appearance is ordinary Portland cement, inorganic lightweight material, setting accelerator and steel fibre, and the content of each component is:
Ordinary Portland cement: 30～60%
Inorganic lightweight material: 15～30%
Steel fibre: 2～5%
Setting accelerator: 0.5～5%
Water: 18～34.5%
Water in the component is to be used for stir mixing, and some is used for hydrated cementitious, and unnecessary water is all taken out when vacuum dehydration.
It is as follows that above-mentioned steel fibre strengthens ordinary Portland cement wallboard preparation method: the each component of above-mentioned content is added 18～34.5% water and mix, stir with blade-less stirrer, blade-less stirrer does not damage fibrous material and dispersed fabulous, mixing time is also short, after stirring, through screw pump squeeze note cloth, rubber screw pump preferably, homogenizing and the squeeze note second time by screw pump, the processability of compound is greatly improved, and through punching automatically, compound is injected into moulding form vibration moulding then, such compound is easy to be full of mould, can reach desirable moulding purpose.With the mold pressing car mold pressing vacuum mat is pressed in vacuum dehydration on the mould, the excessive moisture suction is gone, treat not automatic core-pulling during initial set of cement, saved the time so greatly, from vacuum dehydration finish to automatic core-pulling only number pick up second and can finish, saved the production time greatly, adopted quiet stopping then, operations such as maintenance can be prepared into steel fibre and strengthen light energy-saving wall board.
The steel fibre that wallboard preparation of the present invention is used is the short steel wire fibre that chops up, fibre length is 0.5～5cm, cross section path length 0.2～3.0mm, i.e. which kind of cross sectional shape fiber no matter, its radical length cross section is very suitable in this scope, the fibre section can multiple shape, and that uses at present has the fiber of cross section as garden shape, square and rectangle, and effect is all fine.It can be cut by normal carbon steel fibre weak point and form.
Its particle diameter of inorganic lightweight material that uses in the wallboard preparation of the present invention is 0.5～20mm scope, and unit weight is 50～500kg/m
3Scope.So the inorganic lightweight material of scope can be dispersed between the each component preferably, makes the wallboard weight of making reasonable again.These inorganic lightweight materials can be expanded perlite, lightweight kieselguhr, haydite, foam glass etc.
Ordinary Portland cement is used in wallboard preparation of the present invention, is generally 325#～625# silicate series cement, and in PH=11～15 scopes, they have portland slag cement, high strength portland cement, expansion portland cement, early strength silicate cement or the like.These kind cement wide material sources, the supply centre is many, and buying is convenient, very suitable a large amount of production materials for walls.
During material of the present invention, according to the different behavior in service of inner, external wall, can suitably adjust component content, during as the preparation exterior wall, cement and steel fibre can suitably increase, to strengthen exterior wall intensity.During the preparation interior wall,, can increase the inorganic lightweight material amount, suitably reduce the content of cement and steel fibre in order to improve heat insulating ability.
Steel fibre of the present invention strengthens the ordinary Portland cement wallboard because component is reasonable, has guaranteed that wallboard weight is light, good heat insulating, thereby has played energy-conservation good effect, and other performance such as sound insulation, fire prevention, intensity etc. have also all reached the requirement as wall board material after tested.The used prices of raw and semifnished materials of this wallboard are cheap, only are equivalent to 50% of low alkali cement price as ordinary Portland cement, and the price of finer wire fiber also only is equivalent to 50% of alkali-resistant glass fibre price.Because the present invention has adopted special blade-less stirrer to stir, squeeze through pump again, vibration moulding, vacuum dehydration and automatic core-pulling have shortened the production cycle greatly.Stirring adds pump squeezes component is evenly distributed, and the good result of vacuum dehydration makes the strength of materials obtain bigger raising in addition, is a kind of light energy-saving wall board preparation methods of low-cost and high-quality really.
Embodiment one:
Raw material proportion design: 425# ordinary portland cement 20kg
Finer wire fiber (0.3mm diameter, long 15mm) 0.75kg
Expanded perlite (capacity: 80kg/M
