The specific embodiment
For those skilled in the art can understand the present invention better, will further set forth below.
A kind of preparation method of artificial stone of imitating marble stripe pattern comprises the steps:
A) stir the two or more pug of preparation through homogenizing, have a kind of striped pug that is in the said two or more pug at least,
The plastic range of said striped pug is: hold with palm and pinch the walk material that pug forms; Drop on the ground by 30cm height freely falling body; The pairing phenomenon of its lower limit is, this walk material can be not broken and a side that be impacted clapped by the part, the pairing phenomenon of its upper limit is; This walk material can be cracked except that not and a side that be impacted clapped by the part, and freely falling body can not shakeout in 30 second time after dropping on the ground automatically;
B) the two or more pug that step a) is prepared converges and makes shape and stir, and makes the striped pug under stirring action, become strip;
C) vacuumize and cloth to mould;
D) vacuum vibrating compacting; Solidify.
Division is following:
A) stir the two or more pug of preparation through homogenizing, have a kind of striped pug that is in the said two or more pug at least,
The plastic range of said striped pug is: hold with palm and pinch the walk material that pug forms; Drop on the ground by 30cm height freely falling body; The pairing phenomenon of its lower limit is, this walk material can be not broken and a side that be impacted clapped by the part, the pairing phenomenon of its upper limit is; This walk material can be cracked except that not and a side that be impacted clapped by the part, and freely falling body can not shakeout in 30 second time after dropping on the ground automatically.
Pug is prepared by batch, and batch stirs and just can obtain pug.Contain two big constituents in the batch, one type is resin combination, and one type is aggregate and filler.Resin combination generally comprises resin, initator, promoter etc., and wherein initator, accelerator dosage are very little, and the two content adds up to and often is lower than 2% of resin content.Resin is generally selected unsaturated polyester resin for use.Aggregate is meant particle and to block marble, corresponding order number is 4 orders～400 orders.Filler is meant the fine-powdered marble; Granularity is that 400 orders are so that thinner powder is called fine powder; Powder particle size more carefully is beneficial to plasticity more and increases; But it is also high more to inhale the resin rate accordingly, although even carefully also can use in principle to 1500 purpose fine powders, too high resin demand makes economically the too high and forfeiture product practical value of cost.
Need to prove, so long as can stir the striped pug prepare through homogenizing, all be can realize of the present invention.In addition, in the batch of pug, also comprise or do not comprise the admixture of a small amount of special decorative effect, like broken two-way mirror particle, shell or shell fragment and so on; Moreover, also comprise or do not comprise the colorant of painted usefulness, no matter be that inorganic pigment or organic pigment all can be selected for use.For candy strip of the present invention prepared purpose, aggregate or filler were that above-mentioned marble perhaps partly or entirely substitutes it with other stone material kind such as granite aggregate actually, can not be affected; But in a single day the aggregate or the filler of granite or quartz and so on high rigidity stone material are mixed; Will make the gang saw cutting processing of waste material become especially difficult or even unworkable; Also increase the complexity of the hardness formation of whole system in addition, thereby cause the polishing performance variation; Thereby, only use marble aggregate and filler in the existing common processes in the waste material method artificial stone.
The inventor recognizes that in developmental research various compositions are different for the influence of pug processing performance and product performance in the artificial stone batch.Aggregate thick and mutually the space big, the ability of infiltration resin is strong, particle slightly causes coefficient of internal friction big and be tending towards loose stacking states again simultaneously, it is tight to be not easy compacting; On the other hand, aggregate intensity is high, can promote the artificial stone product strength to improve, and the product compression property after the abundant compacting is little.
Based on the above-mentioned drawback of aggregate, must add the filler of some in the artificial stone pug, the fine powder state of filler has determined its a series of characteristics, and cohesive strength is big as interior frictional resistance is little, and the infiltration resin ability is little, gives pug bigger plasticity.But then, filler is because specific surface is big thereby suction resin ability is strong, and excessive resin can cause the artificial stone product coefficient of expansion big, is prone to disadvantages such as warpage, so the filler use amount must be controlled at certain scope.
Therefore, the aggregate and the filler of striped artificial stone pug must guarantee rational grating, certainly to the pattern effect of the final products space of a whole page, this grating yet need satisfy simultaneously the decorative detail program requirement; The pug that grating is good, its resin demand can be realized practicing thrift to the full extent, and coefficient of internal friction is moderate, and plasticity is strong, compacting easily.Thereby in the striped pug aggregate, filler and resin combination separately content should satisfy certain matching relationship, specific as follows
Aggregate (30～70)
Filler (20～50)
Resin combination (8～30);
More than expressing system is 100 weight portions in the batch gross weight.
In the resin type artificial stone industry, pug is the general designation for whole batch material under the state of mixing; Process then is divided into two big types of plate method and waste material methods: in the vacuum vibration compression moulding stage, mould therefor can be divided into two big types: when mold cavity is flatly directly to be pressed into lamellar raw sheet when tabular, this kind technology is referred to as plate method technology; When mold cavity is all very big bulk three-dimensional shape of length and width height; The three-dimensional intermediate products of the bulk that is pressed into are called waste material traditionally; Its volume is generally at 3～3.5 cubic metres, and through just obtaining lamellar sheet material after gang saw and so on the machine cuts, this kind technology is referred to as waste material method technology again.
In the present invention; To stir according to function and be divided into homogenizing stirring and two kinds of system shape stirrings; The former is used for preparing pug, and the latter is used for pug is processed into desired shape, in above-mentioned " summary of the invention "; Be exactly to stir preparation striped pug through homogenizing earlier, stir through system shape then it further is processed into candy strip or fringe area in the plate face.
Core of the present invention is pug to be had under the condition of suitable plasticity, through the proper described striated pattern of system shape stirring acquisition; Striped is meant the long and narrow pencil pattern unit that contains in the pug among the present invention, and its length is not less than 4 with the ratio of average diameter; Step a), b in the front " summary of the invention ") promptly belong to core content of the present invention; Step c), d) conventional steps then only just replenished for the process completeness of description, any situation that wherein relates to and parameter all do not possess creativeness without exception, correspondingly all the present invention are not constituted essential meaning.The present invention does not directly relate to whole prescription: the composition that can contain numerous species in the prescription; And the present invention only concentrates concern can determine the composition of pug plasticity; That is aggregate, filler and resin combination; An artificial stone prescription is as long as thereby the suitable guarantee of this three content separately pug possesses suitable plasticity of the presently claimed invention, promptly applicable to the present invention; Certainly, can in the embodiment of back, see some concrete prescriptions.
Preparing suitable pug is committed step of the present invention.In R&D process; The inventor is devoted to the formation rule and the Study on Preparation of bar shaped textured pattern pattern under pug adhesive property, plasticity and the stirring action; The basis that is relied on is that pug has enough plasticity, as long as pug plasticity is fit to just be applicable to the present invention.
Bonding characteristic, plasticity and technology about pug can be understood like this: can the bonding characteristic of pug be interpreted as the cohesive force of keeping suitable shape, and can think corresponding with physical viscosity notion; Certainly, being defined as of physics medium viscosity, under the shearing force effect, hinder the ability or the characteristic of laminar flow in the viscous liquid between each layer.But; The artificial stone pug never is a simple Liquid; Its main body by have complex granule form with the solids of grating with having organic mixing of multi-component liquid that prolongation in time shows the reaction process characteristic; It is the mixed system that very complicated multiphase solid is followed multi-phase fluid; Therefore its bonding characteristic (or viscosity) is difficult to adopt simple apparatus measures, and for example the Engler viscometer of popular " deciding the timing of volume of liquid from the outflow of the thin bore downcast hole of volumetric standard " just lost efficacy useless in the industry.Therefore; Among the present invention then the bonding characteristic and the plasticity that adopt the description of flow deformation characteristic aspect to describe pug; Simultaneously, hold the pug group of firmly pinching tight in one's hands through the deformation characteristics after suitably the height freely falling body collides on cement flooring or the hardboard even also use hand to pinch sensation, palm---cracked loose off or because of plasticity enough not spallation still be one whole but profile is hit degree flat and then that the stream exhibition is shakeout by appropriateness---describe; Practical experience proves, the classification of describing based on plastic deformation ability like this can be played directive function with the experiment or the operation of control to the formation of stirring down floral designs in the pug.
Therefore, we are divided into following several types with the artificial stone pug, and it changes according to plasticity from low to high successively:
(1) loose sand shape pug can not be suppressed closely knitly during the compacting of waste material method, be not suitable for artificial Waste stone material method compacting.
(2) granule spherical shape pug; Particle diameter usually≤5mm; The pug of this state presents the roundlet point-like of numerous dispersions on artificial stone plate's face, and since granule be difficult in mixer, receive abundant shearing so that resin to be difficult to dispersed with stirring even; Particle has the feature difference of kernel and outer ring as a result, show color and texture the two one or both of inhomogenous characteristics simultaneously.
(3) agglomerate pug; Granule adhesion gradually becomes increasing agglomerate, help the artificial stone compacting, but this kind agglomerate is under the effect of paddle shearing force; Loose opening easy to crack; This pug is held the group of pinching tight in one's hands through palm, from suitably highly for example approximately 30cm height freely falling body drop on the hardboard (or on ground) promptly can spallation and no longer keep original bulk profile, waste at present material legal person makes in lapicide's skill to pug compacting and takes this state mostly.
(4) striped pug; The characteristics of striped pug are: pug is soft; Plasticity is higher and certain limit is arranged, and holds the pug group of pinching formation with palm and drops to the scope that the phenomenon that produces on ground or the hardboard is explained said plasticity by 30cm height freely falling body, and the pairing phenomenon of its lower limit is; This pug group can be not cracked and this side that is impacted clapped by the part; And the pairing phenomenon of its upper limit is, this pug group except that not broken and clapped by the part, go back freely falling body and hit back, ground (or falling to hardboard) and in 30 second time, can not shakeout automatically; The pug that is in such plastic range is difficult for splitting when under the effect of mixer shearing force, pushing mutually with pug; So compelled plastic deformation; Pull into form, and owing to pug under this state can not flow freely, diffusion and finely dispersed ability are relatively poor when stirring for long stria; When being no less than this pug coexistence of two colors, be difficult for being stirred and form homogeneous color plate face, therefore be suitable for the production of multicolour striped artificial stone kind.
(5) muddy pug, its characteristics can be described as, from suitably highly for example approximately 30cm height freely falling body drop on the hardboard; Not only can be not cracked, and in 30 second time, can shakeout automatically, that is; But pug presents flow regime under this state; Be prone to stir, but the too high pug with press device of cost glues many reasons such as wall pollution or cleaning difficulty, the general production that also is not actually used in waste material method artificial stone product based on its resin expense is too much.
Among the present invention; Stir through homogenizing in the two or more pug of preparation, have a kind of striped pug that is at least, just above-mentioned (4) plants pug; The plastic behavior that has possessed the striped pug has just had the basis for preparing the linear marking artificial stone of form and position random distribution.
The preparation of striped pug realizes than being easier to; The ratio of unsaturated polyester resin (together with its initator and promoter) slurries in the adjustment batch and aggregate, filler; Can test after reaching evenly through the homogenizing stirring, the characteristic that meets the said striped pug of above-mentioned (4) point can be judged to be the striped pug.The plasticity of pug described in the embodiment after a while is all through such judgement.
B) the two or more pug that step a) is prepared converges and makes shape and stir, and makes the striped pug under stirring action, become strip
This step is that described two or more pug stirs the link that obtains said candy strip through blending together, make shape.
The inventor discovers that different pugs can present different change in pattern in the process of making the shape stirring.
Referring to Fig. 2, picture is the signal of granule spherical shape pug.
Referring to Fig. 3 a and Fig. 3 b, its be the agglomerate pug before system shape is stirred with after two states illustrate.
Referring to Fig. 4 a and Fig. 4 b, its be the striped pug before system shape is stirred with after two states illustrate.
Can know that from the comparison of Fig. 3 a, 3b and Fig. 4 a, 4b the agglomerate pug owing to shear action is split, becomes independently small-sized agglomerate pug after system shape is stirred; And the striped pug does not remain integral body under system shape stirring action cracked but distortion has taken place, and it is elongated to be stretched, and becomes irregular linear marking.
In this step; The problem that should be noted that is; Unsuitable long to the system shape mixing time of striped pug, prolong evolution degree that the striped pug is elongated with mixing time and be among the process of continuous variation, as long as can make the striped pug under the stirring action of appropriateness, become the needed strip of target; The technical staff can come the rough degree that reaches that stirs of judging through observing the pug superficial makings; Combine the empirical law of accumulation in the test practice again, contrast the required grain effect that reaches, be chosen in reasonable time and stop to stir.Because if system shape mixing time is long, the striped pug also can too and not have tangible difference with other pugs mixing so, also just no longer has the linear marking pattern." making the striped pug under system shape stirring action, become strip " is the restricted description to stirring extent; Promptly any time before the strip that the striated pug forms disappears stops to stir and carries out subsequent step, can prepare the artificial stone of striated pattern.
Need point out; The form of system shape whipping process discal patch varve material develops; Be under the comprehensive function of very complicated stirring action factor with in the motion state, to take place, in arbitrary moment of this process, the concrete condition of formed various striped is more than the complicacy of said Fig. 4 a, 4b signal; The present invention with these characteristics be summarised as form at random with the position at random; Abbreviate form and position as at random, its implication for example is: aspect the form or elongated or tubbiness is crooked or an exceptionally straight even same striped also is thick or thin etc. on its total length, aspect the position or intensive or become estranged or keep to the side or placed in the middle etc.; Therefore, every artificial stone that is prepared into according to the method for the invention is no matter whether its candy strip is in patent specification literal, drawing, photo is described within the characteristic range or outward, all belong among the scope of the invention.Fig. 5 is based on the photo of the artificial stone of the inventive method preparation, and the change of candy strip in the picture is multifarious, has embodied the implication of enriching of " parian striped ... " in the title of the present invention strictly according to the facts.
C) vacuumize and cloth to mould
This step is the step of a routine.After the striped pug forms striped, have control be unlikely to for example slowly stir under the stirring that obvious change formed candy strip as far as possible, make pug pass through the feed opening cloth to mould; Purpose with candy strip is irrelevant, and the height of vacuum shows influences the residue gas porosity, be generally-more than the 0.077MPa, be preferably-more than the 0.096MPa.
D) vacuum vibrating compacting; Solidify.
This step is the step of a routine.Vacuum requires with meaning the same.Mould is delivered to the compacting chamber; With the pug compacting, in this process, the striated pug can further flow under the state of the certain pressure that dither and pressure head apply; Also still further distortion can be under the vibration of pressure head and squeezing action, produced, the formation effect of the striped space of a whole page can be strengthened.
Compacting is cured later on, just can obtain artificial stone after the demoulding.Curing can be adopted normal temperature cure, or be heating and curing can, preferably use normal temperature cure, normal temperature cure is to be statically placed under the environment temperature of a workshop or particular place to solidify.
The artificial stone of the demoulding generally also need carry out subsequent treatment can actual be used, and for example cuts, processing such as polishing.
