Prior art points out, utilizes polymer materials to make lathe base with becoming a kind of matrix material as the grouan fragment of filler is bonding.These examples were once worked out according to 2/1980 technical notes by Ciba-Geigy and were bound into book form.Here described by a kind of cement special and granite aggregate and with and the epoxy " concrete " made.
Described a kind of machinery bed in Swiss Patent 612610, it forms sand and gravel mixing bonding by synthetic adhesive.At the paper that is entitled as " acrylic resin concrete " (Werkstatt und Betrieb 115(1982) 11. by H.Schulz and G.Nicklau write) prior art narrated spoken of and used acrylic resin and basalt to manufacture the base of panel material and measuring machine.In United States Patent (USP) № 4,382,820, a kind of member of nonmetal type has been described as lathe base.Wherein wash with water, concrete or the pottery as basic material, again some solid materials are resembled fiber, filament and metal and add in the above-mentioned basic material as strongthener.Can consult in 1052 to 1058 pages of industry and engineering chemistry (Industrial and Engineering Chemistry) the 23rd the 9th phases of volume " grading of aggregate " literary composition and U.S.'s ceramics can be rolled up by magazine (Journal of American Ceramics Society) the 44th as the orthopedic gradation that will obtain the solid material maximum density, the 10th phase, 513 to 522 pages, " the machinery filling of spheroidal particle " literary composition.
Use a kind of solidified plastics to fill space between solid particulate, can make the quantity and the volume minimum in space, with the dispersion solid particle compression moulding of this volcanic rock material that various granularity is different.Thereby make rigid articles obtain high strength and damping property, in prior art, all do not set forth for the method for using the volcanic rock material like this.In prior art, do not disclose varigrained basalt solid particulate and Plastic Resin yet and also made the content of the moulded piece of a kind of unique properties described herein with compression moulding.
An advantage of the invention is provides a kind of matrix material of manufacturing moulded piece, this composite material by adopting the unique combination of a kind of volcanic rock material and a kind of solidified Plastic Resin.Another advantage of the present invention is to utilize the representative of basalt as the volcanic rock material, uses with cycloaliphatic epoxy resin, has made a kind of intensity height, the moulded piece that damping property is good.After this moulded piece was deviate from from mould, its outward appearance light was smooth satisfactory; Can expect to be added in the matrix material of this uniqueness with assisting to add, make the moulded piece of different shape; The method of manufacturing moulded piece is simple, does not need special instrument, also needn't repair processing and just can make a kind of space matrix material seldom.
The matrix material that adopts mold pressing of the present invention to manufacture can embody above-mentioned advantage and overcome the deficiency of prior art.In matrix material of the present invention, the dispersion solid particle of the volcanic rock material that various viscosity is different is that the mode of the quantity of particle voids and volume minimum is arranged and compacting.A kind of plastic material of solidified is filled among the space between solid particulate and provides a kind of matrix material for it.Employed volcanic rock material is basalt preferably, and basaltic content is more preferably greater than 70% of whole matrix material volume, resin content is most preferably less than 70% of whole matrix material volume, as for adhesives, alicyclic ring based epoxy resin preferably, especially the multipolymer with two (2,3-oxirane ring amyl group) ethers and ethylene glycol is best.In order to make the toughness maximum of moulded product, selected basalt material should so that make their closely contacts easily, thereby make mutual space quantity minimum at least by three kinds of varigrained granulometric composition.
The invention allows for a kind of peculiar methods of manufacturing moulded piece, in this method, according to the particulate different grain size, the various dispersion solid particles of volcanic rock material are evenly dispersed in the mould, through overcompaction, make the intergranular space minimum, then resin material is added to around these particles, so that fill the space and get rid of wherein air.In order to fill space and excluding air, adopt the method that adds Plastic Resin at mold bottom from bottom to top, to keep a definite resin-air interface.For resin flow optimum behaviour is done, before resin adds in the mould, should be earlier with solid particulate and resin heating.As everyone knows, reduced the viscosity of resin by heating.
By the accompanying drawing of reference this paper, will have preferably content of the present invention and the method for manufacturing moulded piece and understand.
Fig. 1 is a synoptic diagram, illustrates according to principle of the present invention resin is injected the exemplary production system that mould is manufactured module.
The section plan of Fig. 2 for being done along 2-2 line among Fig. 1, illustrate after the moulding material component of the present invention.
Fig. 3 is another concrete module, illustrates a moulded piece that geometrical shape is different.
Fig. 4 is a vertical cross section, illustrates a kind of method of resin being injected mould.
Fig. 5 and Fig. 4 are similar, illustrate the method that another injects resin.
Fig. 6 has compared some performance of the volcanic rock that comprises grouan and basalt.
Although many igneous rock can be used in the composite, optimal orthopaedics is the various basalt with high strength and high-modulus. The representational parameter that they have is:
Compressive strength 64,000 P.S.i
Hot strength 3,200 P.S.i
Modulus 12,000 P.S.i of elastic compression 30
Elastic tensile modulus 17,000 P.S.i
Should be noted that on mineralogical composition and crystalline-granular texture, basalt and grouan have tangible difference.It is acid that grouan is, and basalt is alkalescence.When the early stage geologic epoch formed, the basalt lava of ejection sharply cooled off, thereby forms superfine crystal grain; And the speed of cooling of grouan lava is very slow, thereby has formed very big crystal grain and heterogeneous texture.The physicals of coarse grained grouan is poorer than the basaltic physicals of compact grained.
Basalt mainly is made up of natural plagioclase (about 85%), and all the other are pyroxene (pyrozene) and peridotites.
Obviously lack quartz in the basalt; And grouan contains the quartz more than 25%.Some characteristic of basalt and grouan contrasts in Fig. 6.Here in three-dimensional plot, illustrate their key distinctions aspect mineral constituent and grain size.
Employed basalt particle should be according to size classification thorough drying then among the present invention, so that the unlikely resin that is aggregated of moisture absorbs and hinders its normal curing.In order to reach this purpose, should build the crushed aggregate bunker.For resin is fully solidified, should in this storehouse, feed warm air, so that make it pass through aggregate.Perhaps replace warm air to carry out drying with vacuum drying method.This method just need vacuumize the aggregate bin limitation, so that the moisture evaporation of aggregate surface is fallen.Also having another to make aggregate exsiccant method is to use a kind of chemical seasoning material resemble the portland cement simultaneously.
Though various resin materials can both be used for as the component of this matrix material, employed in the method for the invention some cycloaliphatic epoxy resin class is best.For example, the ERLA-4617 cycloaliphatic epoxy resin that obtains from union carbide corporation (The Union Carbide Corporation) is the multipolymer of two (2,3-oxirane ring amyl group) ethers and ethylene glycol under tertiary amine catalytic.Following table 1 has shown that the performance of ERLA-4617 high-strength resin and ERLA-2772 ordinary resin compares, and the latter is dihydroxyphenyl propane-3 a chloro-1,2 epoxy prapane Resins, epoxy, also can obtain from union carbide corporation.

Basalt is after crushed with flushing with clean water and dry.
The internal surface of satisfactory mould (shown among Fig. 4 10) should carry out polished finish in advance, makes it reach suitable surface smoothness.Mould in this example is a rectangular configuration, and it is long to be the 2-7/16 inch, and wide is the X2-5/8 inch, and height is the 12-1/8 inch.This mould inner surface scribbles the suitable remover of one deck, and for example MM S5050(Ecolab.Inc. sells).Resin, solidifying agent and mixture of catalysts are prepared when being heated to 100 ℃.
The basalt aggregate is placed in the good mould of prepared beforehand, and with suitable compacting means, for example pneumatic hammer carries out compacting again.Be heated to 100 ℃ mould with through the aggregate of compacting then.Then 100 ℃ of flowable resins that prepare down are injected in the band pressure vessel, are injected in the mould by a conduit (shown among Fig. 4 16), flow velocity can be controlled with a pressure-regulator.Injection pressure upwards is adjusted to 10 pounds/inch of maximum gauge pressure values gradually
2(PSig).Along with resin raises along mould, just kept a definite resin-air interface, constantly got rid of air and filled the intergranular space of solid basalt simultaneously.
As shown in the figure, through the basalt particulate different grain size numeral 11,12 of compacting, 13 mark.The basalt particle that numeral 11 refers to maximum particle size, its granularity be-the 3/4+3/8 order, and numeral 12 refers to medium-grained particle, and its granularity is-8 ± 16 orders, and digital 13 is the particle than small grain size, and its granularity is-the 50+100 order.Numeral 14 is the arborescens plastics, and it is filled in the intergranular space of basalt, makes the moulded piece resemble the machine element thus.
After moulded piece is deviate from from mould, its surface-brightening is smooth, core and hole seldom.Before the use, need not it is carried out further surface treatment.
From example 1, can see, just can keep a definite resin-air interface to the effect of resin by means of gravity.In addition, mould is applied other the field of force, for example centrifuge field also can be kept a definite resin-air interface.For example, make the mould motion, just can produce a centrifuge field by rotation or alternate manner.In the example of back, resin is to inject from the neighboring of mould.
Example 2
In this representative instance, employed alicyclic epoxide compound refers to the ERLA-4617 in the table 1.The using method of this specific resin and all identical with example 1 with the proportioning of basalt aggregate.
Here employed suitable solidifying agent refers to the m-phenylenediamine.All other conditions of injecting resin and cast matrix material all with before example 1 stated the same.
Be noted that a kind of method of injecting resin material varigrained between the basalt particle 11～13 of overcompaction has been described among Fig. 4.Here, resin material is under the effect of pressure, injects from the bottom of mould by conduit 16.If necessary, also can use among Fig. 5 20 such moulds.Be used for resin deliver to from the top of mould one of mold bottom fixedly filling tube 23 be placed on the pipe 21 and be coaxial with it.Resin at first injects from mold bottom, and this is for upwards exhausted air is very favourable because when resin gradually when the bottom is full of mould, air is present on the interface all the time.Another advantage that has the mould device 20 of a telescopic filling tube 23 is to regulate the liquid level of resin by stretching of filling tube 23, and in order to inject resin gradually and to drain air, can select a position more than 22 at side opening.
Fig. 1 represents the typical process flow of a large-scale feeding device, and the throughput that it produces the moulding press bed member is very high.Large quantities of resins is transported to resin raw material basin 34 and the solidifying agent basin 30 from tank car 31 by suitable transfer lime 32 and 33.Resin and solidifying agent will be transported in the conditioning tank 38 by pipeline 35 and 36 respectively by pump 37 and nurse one's health.Then the material through conditioning is transported in the batch mixes machine 40 by topping-up pump 39.Suitable tinting pigment is added in the moulded piece, and this pigment is stored in the basin 45, and by connecting the transfer lime 41 and 42 of conditioning tank 38 and topping-up pump 39, is transported in the batch mixes machine 40.By again the material through mixed preparing being injected in the mould 41 of aggregate here.
As previously mentioned, illustrate Manufactured molded composite material among Fig. 1 and Fig. 2.Among Fig. 2 16 represented be the rectangular cross section of the matrix material after from mould 41, taking out.
Fig. 3 has described another geometric configuration 50.This specific concrete member has been simulated typical worker's one supporting beam.It should be noted that basalt particle 11,12,13 is in the compaction state of tight contact in the particular elements of the present invention, and surrounded by arborescens plastic bonding layer.
Can expect that aspect other important purposes, such composite is unrestricted when being molded as bathtub, manhole cover, door handle, furniture and structural material. In some illustrated epoxy resin, preferentially select cycloaliphatic epoxy resin herein. Except using the bisphenol-A epichlorohydrin epoxy, also can use the epoxy resin of other class, such as phenolic resins and line style aliphatic epoxy resin, still can obtain desirable characteristic. Although some epoxy resin had been done description, the resin that other viscosity is very low refers to mylar or methacrylic resin, and they can form desirable bonding between the granite of the various viscosity of compacting.
Preferably use at least three kinds of varigrained igneous rock particles. If required, also can use the different particle of granularity more than three kinds, as above narrate, the particle of smaller particle size can be full of the space between larger particles. Should be noted that in order to obtain the uniform high strength goods of quality in process, the full-size of particle should be lower than 1/3 of the wall thickness that contains this material members. Although in the above example, epoxy resin is independent and basalt and usefulness, if necessary, other reinforcing material or filler also can and be used with the basalt particle such as steel disc or steel fibre.
Use steel disc and steel fibre can improve its intensity and toughness as composite reinforcing material. Steel disc is filled in the composite can improve its damping performance; Have a large amount of polymer interlayers between the steel disc that is separated from each other, all these polymer interlayers play catabiotic effect when member deformation, and the composite that is filled with like this steel disc has good damping capacity. The composite that steel disc and/or steel fibre are filled has the characteristics of the high and good toughness of intensity, and this is just because of the intensity height of filler, due to good toughness and their the high bearing capacitys. High bearing capacity be since they in length and breadth (size) than due to.
As mentioned above, a key character of the present invention be varigrained igneous rock particle tightly compacting in mould, use then curable resin filling plastic. For obtain resistance to shock that maximum toughness becomes reconciled use a large amount of igneous rock materials a small amount of and to use the resin plastics be very necessary. If specific igneous rock is basalt, and be the epoxy resin resinous materials with it and with what play bonding effect, wherein one of polymer unit in this copolymer is two (2,3-epoxy radicals cyclopenta) ether, so, can also obtain other benefit.
The invention provides unique composite materials of making machine bed member mechanograph, raw material obtains easily and very high intensity and damping behavior can be provided. Material used in the present invention is quite cheap, therefore very suitable cheap composite and the goods of being made into. In addition, after product of the present invention took out from mould, surface-brightening was smooth, and with colour, outward appearance is satisfactory, need not to carry out surface treatment before therefore using again.
Although, in order fully to disclose actual mechanical process of the present invention, done detailed description for the illustrated instantiation of the present invention, but, should be understood that, given concrete member such as material mixture ratio only are in order to illustrate, yet as long as without prejudice to spirit and the technical scope of hereinafter appended claim, the characteristic of so various novelties all can embody in other version.
