Abstract
A process for preparing high-granularity granite plate includes mixing resin, solidifying agent and catalyst to obtain adhesive, coating it on paperboard template, sticking grnaite slice, filling granite particles, adding the mixture of small granite particles, stone bits, quartz powder, resin, solidifying agent and coupler, vibrating, shaping, thermal solidifying, ageing, and surface treating.
Description
The present invention relates to a kind of new decorative material for building, particularly a kind of bulky grain reproduces the manufacture method of granite in slab.
Agglomerated stone reproduces, turns waste into wealth and gain the name through bonding for the stone material particle because of it.Present domestic agglomerated stone sheet production method is that the stone grain of getting fine grain adds the polyester unsaturated-resin after grating, curing agent mixes the rear fender moulding.This moulding process is compared the balk moulding and has been saved resource, has improved production efficiency, but this agglomerated stone sheet material is the fine grain particle owing to what use, and the whole stone texture of product surface is poor, thereby has influenced the decorative effect of agglomerated stone sheet material.
Purpose of the present invention just provides the manufacture method of the extremely strong bulky grain agglomerated stone sheet material of the whole stone texture in a kind of surface.
The present invention can be realized by following mode: (1) gets 1% anti-corrosion resin, an amount of curing agent, catalyst by weight percentage, mixes to stir and makes the even brushing of adhesive on stiff paper form; (2) get by weight percentage that 40～43% thickness, 15～18mm, length are not less than 130mm, area is not less than 0.004m
2, be not more than 0.014m
2Irregular granite block section evenly sticks on the stiff paper form of having brushed adhesive, makes the gap of reserving 20～25mm between the granite block section; (3) (particle diameter 1 5～20mm) big particle diameter granite grains evenly stick between the granite block section gap to get 4～5% by weight percentage; (4) getting particle diameter by weight percentage is that 4～6mm granite grain 10～13%, particle diameter are 2～4mm granite grain, 10～13%, 20～100 order granites quarrel, 15～18%, 300～325 order quartz powders 10～13%, anti-corrosion resin 6～8%, curing agent 0.1%, an amount of coupling agent, drops into mixer and stirs; (5) mixture of granite grain in the mixer and resin is put on the stiff paper form in (1) floating and vibration; (6) stiff paper form after the floating jolt ramming is sent in the punching block of make-up machine, the punching block temperature is 90～120 ℃, and make-up machine high pressure matched moulds, pressure are 10～13Mpa; (7) heat high pressure after 5 minutes, granite grain and resin compound be curing molding, sends into drying room and carries out 24 hours burin-in process of heating, and temperature is 150 ℃～170 ℃; (8) goods are carried out bottom surface corase grind, surface corase grind; (9) goods after the corase grind of surface are repaired; (10) polishing of the product surface after will repairing then, is cut, is waxed.
Superficial layer of the present invention can reach 60 gloss unit after polishing, superficial layer is that granite block section, big particle diameter granite grain are formed, thereby makes the whole stone texture of product surface extremely strong.The present invention makes full use of the leftover bits and pieces of natural crystal resource, and comprehensive utilization of resources has with low costly, can realize auto industrialization production, the production efficiency height, and characteristics such as properties of product are stable are widely used in office building, auditoriums, hotels, family indoor and outdoor wall ground is fitted up.
Below in conjunction with embodiment, the invention will be further described.
Embodiment one (to make 580mm * 580mm * 18mm, gross weight 19.4kg is an example).
1, prefabricated stiff paper form
Get resin 0.2kg, add an amount of curing agent, catalyst, puddle earlier evenly, brush then on stiff paper form, 8kg thickness 16mm, long 120mm, area 0.01m
2Irregular granite block section and the big particle diameter granite of 0.8kg grain (diameter 18mm) stick on hardboard and are coated with on the brush layer, the gap that 20mm is arranged between the granite block section, the stone grain evenly sticks between the gap of granite block section, flag and stone grain are covered with the stiff paper form area more than 70%, reserve the gap of 8mm between granite block section and the big particle diameter granite grain.
2, the stirring that mixes of resin and building stones
Get resin 1.3kg, add an amount of curing agent, coupling agent, puddle earlier evenly.Get fine grain granite grain (diameter 4mm) 2kg, fine grain granite grain (diameter 2mm) 2kg, 100 order granites quarrel 3kg, 325 order quartz powder 2.1kg, above-mentioned raw material are dropped into mixer stirred 5 minutes, it is stirred.
3, floating, vibration
In the granite material and the prefabricated stiff paper form in the resin compound input (1) that stir, cardboard four edge breaks are risen, form a container.Floating again compound is put on the oscillating table and was vibrated 3 minutes, makes its jolt ramming and discharges bubble.
4, the high-pressure molding of heating
Mixture after vibration is under the support of cardboard mould, deliver to make-up machine by conveyer belt, one mold is installed in the make-up machine (emptyly in the mould is 604mm * 604mm), be divided into upper die and lower die, when upper and lower mould was opened, ultimate range was 0.5 meter, thermocouple and electrothermal tube are housed in the upper and lower mould, the patrix temperature is that 110 ℃, counterdie temperature are 100 ℃, earlier patrix is opened to highest point, and the cardboard mould that compound will be housed is then sent in the counterdie.
Make-up machine produces high pressure with upper and lower mould matched moulds, and this moment, pressure was 12Mpa, heating high pressure conditions after 5 minutes, opened patrix, and at this moment, the compound in the mould is curing molding.Because compound periphery and below the cardboard mould is arranged, one deck brown paper is arranged above, so, can sticking to mould.Three automatic square thimbles eject the goods of forming, put into drying room and carry out 24 hours burin-in process of heating, and temperature is 160 ℃.
5, back side corase grind and positive corase grind
The granite block section is decided to be the front with cardboard mould stickup face, the floating face of the mixture of granite material and resin is decided to be the back side, grind off surperficial glue-line with diamond disk at the corase grind back side, make product when paving, can paste firmly with cement mortar, and the flatness at the assurance back side, treat the back side to grind smooth and coarse surface occurs, and when exposing chicken girt fully (grinding off 1.5mm thickness approximately), promptly goods are upwards transferred to by the back side and facing up, carry out front corase grind (grinding off 1.0mm thickness approximately) by the automatic panel-turnover device.
6, goods are positive repairs
Goods are delivered on the repairing platform, and goods face up, and get 325 order quartz powder 0.2kg, and anti-corrosion resin 0.12kg, an amount of curing agent, promoter mix, and is with compound that the dit in goods front is floating, solidifies with hot blast then.
7, the positive mirror polish of goods
Goods are repaired towards last, carried out surface finish with automatic polishing and burnishing machine.Polish the 0.5mm thickness that weares and teares approximately, polishing back product thickness is 18mm.
8, cutting
Polished goods are carried out deburring cutting with automatic gas cutting machine, are cut into the specification of 580mm * 580mm * 18mm, and cut smooth, do not collapse and lose.
9, waxing
Waxing is better maintained the surface of product, in use is difficult for immersing spot.After classification and Detection and packing can dispatch from the factory.
After testing, product physical and chemical index: glossiness 〉=60 gloss unit, Mohs' hardness 〉=6.5, hardness Barcol 〉=50, rupture strength 〉=8.5Mpa, compression strength 〉=90Mpa, density 〉=2.42g/cm
