Embodiment
Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.Following embodiment just provides in order to help to understand content of the present invention, and those of ordinary skill in the art can carry out various changes in technological thought scope of the present invention.Therefore, claim scope of the present invention is not to be defined in described embodiment.
Fig. 1 is for being used for explanation according to the process flow sheet of rostone limestone of the present invention and manufacture method thereof.According to rostone limestone of the present invention, be for comprise cement 35～55 weight %, visually the gross weight of the mixture of the silica sand of differentiable particle shape or glass sand 40～60 weight %, softening agent 0.5～1.0 weight %, cellulosic fibre 1.5～3.0 weight %, sepiolite 0～3.0 weight %, polypropylene 0.1～0.15 weight % is mixed the water of 20～25 weight %, and manufactures various material of construction shapes such as sheet material, external decorative material, interior material, soundproof wall, sash stuff, sculpture, pillar by extrusion moulding or forging type.
Common vacuum extruding form cement uses asbestos, but this asbestos are the fearful materials that bring out diseases such as asbestosis, lung cancer, mesothelioma, and the disease that causes because of asbestos is difficult for being diagnosed, and is difficult to treat.According to relevant research, as long as once be exposed to asbestos, even be not exposed later on, disease also will continue, and can develop into fatal state after about 20 years.Therefore, need to replace asbestos and harmless replacement fiber.But asbestos not only play the effect that strengthens hardness, but also have various functions such as extrudability, model keeping character, moisture retention, therefore are difficult to replace asbestos with a kind of fiber merely.Thereby the present invention does not use asbestos, and blended cellulosic fibres, sepiolite, polypropylene are to replace asbestos.
Mierocrystalline cellulose (cellulose) fiber is produced from timber as organic fibre, and that uses in the present invention obtains from the newspaper shredded paper.Though the hardness of cellulosic fibre and dispersibility are not as other fibers, water absorbing properties is outstanding, and therefore the surface drying phenomenon that takes place in the time of can solving products production has mixed cellulosic fibre.The reason of mixing sepiolite is that it is natural inorganic fiber, has outstanding thermotolerance and dispersibility, thereby can improve physicals.The reason of polypropylene (polypropylene) fiber is, though its poor heat resistance can remedy when extruding the hollow space sinkage of the product that takes place.
In order to embody various color and lusters at the rostone limestone, can use colour silicon sand or the stained glass sand with self color, and also can irrespectively throw in pigment in addition with the color of silica sand or glass sand.
Concrete manufacture method is as follows.
At first, cellulosic fibre is carried out opener (S10).Because of the dispersibility of cellulosic fibre not as asbestos, therefore in order to remedy this shortcoming, through the opener process.As without the opener process, the phenomenon that cellulosic fibre is piled up will take place, and cause condition of surface bad of extrudability and product.The opener of cellulosic fibre can be undertaken by other opener, but also can be earlier being used for dropping into other raw materials after dry mixer that dry type mixes starts cellulosic fibre 60 seconds separately, carry out dry type with this and mix, carry out opener.
Secondly, measure cellulosic fibre, cement, silica sand or glass sand, softening agent, sepiolite, the polypropylene of opener, and drop into dry mixer, making becomes aforesaid weight % (S20).As mentioned above, the opener of cellulosic fibre also can use dry mixer to carry out, and at this moment, the cellulosic fibre of opener in dry mixer, therefore directly devotes dry mixer with surplus stock and gets final product.
At this moment, be characterised in that the present invention uses silica sand or the ORGANDY of the particle shape that can distinguish by vision.When making existing vacuum extruding form cement, used the ground silica of powder shape, but in the present invention, used the silica sand of bigger particle shape.At this, so-called powder shape refers to the size of particles littler than 80 mesh sieves, and what is called can refer to the size of particles bigger than 80 mesh sieves by the particle shape that vision is distinguished.Among the present invention, preferably, use the silica sand of 10 ~ 80 mesh sieve sizes.
At this moment, preferably, silica sand uses environmental protection silica sand, for example jade silica sand, medical stone silica sand, loess stone silica sand, other silica sands to human body beneficial's material.
In order to give surperficial texture and the various color and luster as limestone, its components matching amount is very important, of the present invention being characterized as, and cement accounts for 35～55 weight %, and silica sand accounts for 40～65 weight %.When making vacuum extruding form cement in the past, drop into cement 50 ~ 65 weight %, ground silica 30 ~ 40 weight %, so that the amount of ground silica is lacked than cement, but in the present invention, for the coarse and natural slightly surperficial texture that embodies limestone and soft texture and various color and luster, make the amount of silica sand of the particle shape that can distinguish by vision more than cement.
As silica sand or glass sand, can use colour silicon sand or stained glass sand with self color, thereby give various color and lusters, also can irrespectively drop into pigment with the color of silica sand or glass sand, thereby give color and luster.For the latter's situation, preferably, drop into pigment in the step that devotes dry mixer or wet mixing step described later (S40).
Softening agent is for the oilness of giving cement raw material and viscosity, mainly uses Vltra tears, and the desired viscosity of vacuum extruding form technology is more than the 15000cps.
Then, the dry type of carrying out in dry mixer 150 ~ 240 seconds is mixed (S30).After finishing dry type and mixing, drop into water and carry out 120 ~ 180 seconds wet mixing (S40).After finishing wet mixing, mixture is devoted forcing machine, vacuum extruding form is material of construction shapes (S50) such as external decorative material, interior material, soundproof wall, sash stuff.Vacuum extruding form is that the mixture that will finish wet mixing mixes in mixing machine (small kneader) again, devote forcing machine, and by shift fork screw rod (fork screw), vacuum chamber, wimble (auger screw), gate and finally finish towards film.Outgas at the vacuum pressure of vacuum chamber with about 75mmHg.
The forming composition that vacuum is extruded moves to subsequent technique, and is cut off for the first time, and carry out maintenance (S60) by steam (steam) by the travelling belt that the speed of keeping to be same as extruded velocity moves.Finish after the steam curing, the bending of testing product and condition of surface after carrying out at last cutting off for the 2nd time, are carried out autoclaving (S70).Finish after the autoclaving, through physical property and the last processing of detection, shipping products (S80).
As cement, when using high rigidity cement, even also can obtain the limestone of required hardness without autoclaving (S70), so in these cases, can omit autoclaving (S70).
Fig. 2 is the image that illustrates according to the surperficial texture of rostone limestone of the present invention; Fig. 3 is the image that the surperficial texture of existing vacuum extruding form cement is shown.With reference to Fig. 2 and Fig. 3, in the present invention, because using the silica sand of the particle shape that can distinguish by vision, can embody surperficial texture and the shades of colour of limestone, but existing vacuum extruding form cement then uses the ground silica as the powder shape of flour, and is therefore as broad as long with the very smooth general cement of surperficial texture and color and luster.
As mentioned above, rostone limestone according to the present invention has surperficial texture and the various color and luster of natural stone limestone, and discarded making by hand and die operation in the past, makes artificial limestone in the vacuum extruding form mode, therefore can obtain high-quality product in a large number.Thereby, can supply in the building site endlessly and rebuild on-the-spot required rostone limestone, can also diversity select material of construction, and it is more attractive in appearance that building external is decorated.And, because not using asbestos, harmless.
