Description
Technical field
The present invention relates to a kind of goods and preparation method thereof of artificial sandstone plate.
Background technology
The natural sand rock beam that relates in the prior art has following shortcoming: 1, natural sand rock beam color and luster, texture too rely on natural mineral resources, cause color and luster single, moulding is simple, and it is bigger to manufacture the cost input, needs main equipments such as exploitation, cutting, polishing, engraving, and product is heavier, the cost that increases transportation and install, Partial Physical Property is relatively poor in addition, as flexural strength, when product is thinner, fracture easily; 2, organic material uses as cementitious material, the ultraviolet light weak effect can occur, and time one long products is variable color easily just, and weatherability is poor, the life-span is short; 3, inorganic material is used as cementitious material, and the production cycle is long, production efficiency is low, need just to finish depanning in about 24 hours, and sandrock effect not significantly, have a problem such as surperficial drop.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention aims to provide a kind of artificial sandstone plate preparation method that can the rapid shaping demoulding, not only can enhance productivity, solution can't be made moulding complexity, the different sandstone plate of chromaticness, and the natural sand rock beam is manufactured the problem of the natural mineral resources of undue dependence, easy to change, weatherability is poor, the life-span the is short technical barrier of artificial organic sandstone plate have also been solved, when reducing infusion of financial resources, also shorten the production molding cycle, avoided phenomenons such as the consumption worker is consuming time.
The technical scheme that the present invention solves the problems of the technologies described above is: a kind of goods of artificial sandstone plate, constituted by the surface layer that links together and deck, the component of described surface layer and content (parts by weight) are 100 parts of 42.5 grades of fast hard low-alkalinity sulphoaluminate cements, 3 parts of polyvinyl acetate rubber powders, 5 parts of emulsion acrylic, 70～90 parts in water, color sand stirs pulping for 250 parts, is sprayed on described die surface, sprays twice, 3～5min guarantees surface layer gross thickness 4～5mm at interval; The component of described deck and content (parts by weight) are 100 parts of 42.5 grades of fast hard low-alkalinity sulphoaluminate cements, 6 parts of alkaline-resisting rovings, 5 parts of emulsion acrylic, 100～120 parts in river sand, water stirs pulping for 50～60 parts, is sprayed on the described surface layer, and uses the compression roll compacting, second time structure material of spraying behind the lapping lattice cloth, the compression roll compacting of spray back; 20～25 ℃ of temperature, solidify under the condition of humidity 70～80%, get artificial sandstone slab products after microwave curing, demoulding, the surfacing.
The preparation method of artificial sandstone slab products of the present invention is made by following step:
One, mould is prepared: at first silica gel mould is cleaned out, the soft mode pad is docile, release agent spraying then, and wipe unnecessary release agent with clean rag.
Two, prepare surface layer by ratio of weight and the number of copies, step 1: the component of described surface layer and content (parts by weight) are 100 parts of 42.5 grades of fast hard low-alkalinity sulphoaluminate cements, 3 parts of polyvinyl acetate rubber powders, 5 parts of emulsion acrylic, 70～90 parts in water, 250 parts in color sand; Step 2: pour 2/3 water into mould, polyvinyl acetate rubber powder, emulsion acrylic are added stir again; Step 3: the fast hard low-alkalinity sulphoaluminate cement of color sand and 2/3 is added mould stirred 30 seconds, remaining water and cement are added, stirred 3～5 minutes; Step 4: adopt the special-purpose surface layer rifle of GRC to spray, surface layer is divided into secondary injection, sprays muzzle and mould angle at 45,40～60 centimetres of vertical distances, the compound that step 3 is made is ejected in the mould equably, sprays twice, 3～5min guarantees gross thickness 4～5mm at interval.
Three, prepare deck by ratio of weight and the number of copies, step 1: the component of described deck and content (parts by weight) are 100 parts of 42.5 grades of fast hard low-alkalinity sulphoaluminate cements, 6 parts of alkaline-resisting rovings, 5 parts of emulsion acrylic, 100～120 parts in river sand, 50～60 parts in water; Step 2: earlier emulsion acrylic is added to the water mixing, again mixed liquor is injected agitator; Step 3: stirring in the mixed liquor of river sand, cement, chopped strand adding step 2, mixing time must not be above 3 minutes; All compounds stir the back and used up in 10 minutes, forbid secondary to add water; Step 4: the structure material sprays, treat that surface layer has certain intensity after, with GRC special-purpose ejecting equipment screw rod car, spray first pass structure material earlier, lapping lattice cloth sprays the structure material again second time after spray, every time structure material compression roll compacting.
Four, receive light, make product thickness mold side mouth unanimity; When receiving the light end product is marked numbering.
Five, microwave curing: product is put the microwave machine transport tape successively, by microwave curing, make cement mortar under the effect of microwave, aquation forms hydrate rapidly, improves early strength.
Six, the demoulding: microwave curing finished to carry out after 20～30 minutes the demoulding again to be handled, and the product broadside is vertically placed after the demoulding, and on the limit mouth of band outseam was super, per two back sides were adjacent to.
Seven, maintenance: maintenance in the maintenance room behind the product stripping, the maintenance room keeps constant temperature and humidity, and 25 ℃ of maintenance environment, maintenance is 3 days under the condition of humidity about 85～95%.
Eight, surfacing: pickling or surface sand-blasting.
Nine, surface waterproofing: adopt the hydrophober sprayed product 2 times, every all over 3～5 minutes at interval.
Production environment control among the present invention is in 20～25 ℃ of temperature, humidity 70～80%.
Preparation method of the present invention is with scientific and rational prescription, and through molding procedure such as stirrings, injection, microwave curing, the product after the demoulding finally forms the artificial inorganic sandstone plate of every performance indications excellence again by pickling or sandblast, waterproofing work.But its products obtained therefrom rapid shaping, shorten the mould life cycle, enhance productivity greatly, the inorganic sandrock effect of making is abundanter, plasticity is stronger.
Goods of the present invention are perfect adaptations of natural inorganic material and advanced technology, have brought up the superfine product in the manufactured sand rock beam.The product that the present invention makes not only has durable, the strong firmly texture of natural stone material, sandstone as weathering, in texture, the nature that has all kept true sandstone on color and luster and the texture, the variation, the plasticity that have simultaneously the incomparable color of true sandstone and style again, its sound insulation in addition, heat insulation, waterproof, anti-skidding, weatherability, heat insulation fire retardant, performance such as radiationless and pollution-free are more excellent, thereby all can show unique charm fully in indoor or outdoor decoration.The more important thing is, when guaranteeing properties of product, can guarantee simultaneously to produce this production efficiency of products promotes significantly, promote more than the several times than traditional artificial sandstone board production technology, can guarantee that tame middle-size and small-size scale enterprise artificial inorganic sandstone plate annual production reaches 50～1,000,000 square meters, make that it lowly drops into, high yield.
