Description

Technique of prefabricated decorative board from handstones

Technical field:

The invention belongs to decoration material field, particularly a kind of technology that is prefabricated into by handstone with resistance to water water penetration dalle.

Background technology:

The existing building ornament materials is rich and varied, is many with ceramic, as: floor tile, ceramic veneer, and then development has the Art Stone brick of the imitative bag reason of vitreous brick and surface of any surface finish such as mirror.These Ceramic Tiles moulding process all need through potter's clay grinding, spray do, powder shaping, biscuiting and glaze firing.Complex process, the production process power consumption is big, especially high-temperature sintering process.Ceramic tile still is the ornament materials of main flow on the market at present.Cobblestone is the natural product that people are loved very much, also be employed in more and more in environment and the home decoration, but there is the influence of quality, size and storage in it, can't large tracts of land use; Surface-brightening is its characteristic, also is its deficiency, is difficult to adopt cement to cement, and the ground of decoration or metope phenomenon such as usually occur coming off influences attractive in appearance.Building stones rich in mineral resources, quality is various, utilize the leftover bits and pieces of stone ore exploitation process compound prefabricated decorative board material research topic of the present invention.

Summary of the invention:

The objective of the invention is to create a kind of building stones crushing grinding that adopts and become handstone, and the prefabricated decorative board manufacture craft by the colloid molding bonded.

Technical solution of the present invention is achieved in that a kind of technique of prefabricated decorative board from handstones, it is characterized in that the manufacture craft flow process is:

(1) selects materials: be chosen to the near building stones of form and aspect.The appearance color of more distinctive stone has: chrysanthemum, chicken are blood red, white, green, light brown, dark-brown, pink, wood grain look, topaz, sapphire, jade Huang, agate, crystal etc.Lovely luster, clean mark is the higher former work stone of processing decoration sheet material added value.

(2) preliminary treatment: building stones adopt disintegrating apparatus that it is crushed to the handstone that is not more than 30mm, drop into the extremely surperficial no obvious burr of polishing in the milling apparatus again, rinse and make its drying well.Milling apparatus can be selected the drum unit tool for use, adds the drum ball and polish that (the drum ball can not too greatly can not be too little, if too big, small stone can become stone flour, all scraps in rotary drum; If too little, can not polish carrot-free small stone again), the time is to get final product in 6 to 8 hours, and the handstone after the polishing is with the sensation of surface as frosted, and no burr exceeds; After having polished, screen with the sieve of all size size, after screening finished, water cleaned up, and drying can adopt heat drying or dry naturally.

(3) classification: difference is classified by size, and every class size is more or less the same in 5mm.Be good generally with the not super 3mm of Size Error, as: handstone classification specification is respectively 2mm-4mm, 4mm-6mm, 6mm-8mm, 8mm-10mm etc., and the specification error is more little, and the outward appearance uniformity of sheet material is good more.

(4) gluing: surface cleaning, dry handstone are put into mixing plant, pour glue into, be stirred to the handstone surface and evenly be coated with very thin one deck colloid.The ratio of handstone and glue is to decide according to the specification of the color of handstone and handstone and moisture deal, handstone generally is controlled at 100 kilograms than getting final product in the 6-10 kilogram scope with the weight ratio of glue, glue concentration is in the 500-2000cps scope, handstone is with after glue mixes, mixing time was not less than 20 minutes, made the handstone surface evenly be coated with glue.

(5) moulding: will on have the handstone of thin glue to pour into to be placed in framed on the flat board, suitably vibration makes handstone closely knit, and touches plane surface, deviate from framed, the base substrate curing molding.The curing molding of base substrate has dual mode, and the one, dry naturally, the 2nd, the oven dry of heating, the finished surface fineness after the former solidifies is higher, but solidifies the length that takes time, and the place takies big defective; The latter is more suitable for industrialized mass.The oven dry of heating of base substrate is meant after the demoulding molding blank moved in the baking oven and dries, temperature is decided according to the character of glue, generally be controlled between 50 to 60 degree, high mutability, and influence the service life of product or the fastness of bonding, drying time according to base substrate thickness extent control between 3 to 6 hours, and naturally the cooling get final product.Mode of vibration also has two kinds, first body vibration makes handstone closely knit gradually, and it two is to utilize hand-held vibratory equipment directly to the handstone jolt ramming in framed, perhaps both combine also can, if the surface is not touched and flatly can not produced the protruding naturally Massage pedal of surperficial handstone.

In described moulding process, can in base substrate, add grid cloth in case of necessity, play reinforcement or be called skeleton function, make base substrate more firm, especially when making ultrathin type or ultra-large type sheet material base substrate, avoid product jackknifing in handling process, to occur, if jackknifing also can play correlation, be easy to be reduced to complete during laying.Grid cloth can be in the bottom or the panel middle part of sheet material, its moulding in the following way respectively.

During moulding, be placed with grid cloth in advance in framed bottom, handstone, the demoulding of then pouring gluing into are solidified.

Perhaps, during moulding, the handstone of pouring a part of gluing earlier into repaves a grid cloth after framed bottom is covered, and then pours handstone, the demoulding curing of gluing into.

Above-described grid cloth is the wire rod that general reference has the longitude and latitude wire, as: glass fibre, wire, cotton, nylon wire and macrolattice fabric.

The present invention has the design uniqueness, and technology is reasonable, utilizes less glue, and play related cementation between handstone, and, cause prefabricated panels to have higher permeability not as inserts, but venting and water permeable; Raw material is extensive, can directly select natural handstone for use, more can adopt the stone material leftover bits and pieces, aboundresources not only, and turn waste into wealth, moreover can strictness produce radiationless sheet material; The sheet material wearability that processes is good, and has the bright more characteristics of mill more.
