Summary of the invention
The present invention does in view of the above problems, and its purpose is to provide a kind of can make the synthetic marble manufacture method that outward appearance seems the synthetic marble of natural marble.
Manufacturing method of artificial marble involved in the present invention, it is characterized in that, comprise: the composition of hydrated metal compound that will contain thermoplastic resin, 85～60 weight % of 15～40 weight % carries out fusion when shearing, rubs and close, make its curing obtain composite blank, then this composite blank is pulverized, thereby prepared the operation of basic intermediate; To contain when the composition of hydrated metal compound of thermoplastic resin, 85～60 weight % of 15～40 weight % and colouring agent are sheared and carry out fusion, rub and close, make its curing obtain painted composite blank, then should pulverize by painted composite blank, thereby prepare the operation of painted intermediate; The surface of above-mentioned basic intermediate or painted intermediate is carried out painted, thereby prepare the operation of the 1st, the 2nd surface colour intermediate; Suitably with a kind of in above-mentioned basic intermediate and the painted intermediate and, at least a combination the in above-mentioned the 1st surface colour intermediate, above-mentioned painted intermediate and above-mentioned the 2nd surface colour intermediate, and put in the heating shaping molding box, utilize the heating forming press in last direction molding box, to push, make its fusion, flow, and the operation that becomes one.
One of feature of the present invention is, graininess, sheet or mass foundation intermediate or painted intermediate with different colours, be arranged in the heating shaping molding box on the heating surface, utilize the heating forming press to pressurize from the top, the resin of intermediate is flowed, and become one mutually, at this moment, color (colouring agent) is flowed.
As long as the intermediate of different colours flows, colouring agent flowed at its boundary member when perhaps intermediate flowed, and just can produce the synthetic marble that surperficial apperance seems natural marble.
With graininess, sheet or the block intermediate of composite blank or painted composite blank and, be formed with the surface colour intermediate of the superficial layer of colouring agent on its surface, be arranged on the shaping die face and pressurize, intermediate and surface colour intermediate and colouring agent are flowed, and intermediate and surface colour intermediate are become one mutually, thereby obtain the synthetic marble that outward appearance seems natural marble.
Colouring agent, if with as can forming superficial layer on the surface of resin after the raw-material mixed with resin, which kind of colouring agent all can, but consider hear resistance, preferred mineral pigments.And, as the resin of composite blank and painted composite blank, can adopt thermoplastic resins (comprising the natural decomposition plastics) such as polypropylene, polyethylene, polyvinyl chloride, acrylic resin.
As thermoplastic resin, according to purposes can select polyethylene (PE), PET (PET, PETE), polyvinyl chloride (PVC), PLA (PLA), polypropylene (PP), polyamide (PA), Merlon (PC), polytetrafluoroethylene (PTFE), polyurethane (PU), polystyrene (PS), saturated polyamides, ABS resin (ABS), acrylic resin (PMMA), polyacetals resin various thermoplastic resins such as (POM).
The hydrated metal compound that is added as composite, (kick off temperature is 200 ℃ can to select aluminium hydroxide, caloric receptivity is 470cal/g), (kick off temperature is 380 ℃ to calcium hydroxide, caloric receptivity is 222cal/g), (kick off temperature is 340 ℃ to magnesium hydroxide, caloric receptivity is 320cal/g), (kick off temperature is 250 ℃ to calcium aluminate, caloric receptivity is for 340cal/g) etc. various additives, and in the scope of the physical property that does not hinder this kind hydrated metal compound, can and use various incombustible agents, promptly can suitably use ZnO, lead borate, lead stannate, carbon black, copper nitrate, ferric nitrate, metal organic sulfonate, the phosphonitrile compound, nano composite material (Nanocomposite filler), aerosil (fumed silica), PAN etc.
In the combination of thermoplastic resin and hydrated metal compound, importantly, make the decomposition temperature of hydrated metal compound be lower than the decomposition temperature of thermoplastic property resin, and consider and can mix decomposition temperature and caloric receptivity more than 2 kinds and be used.
Because the combined amount at the hydrated metal compound of hot attribute resin is high, be 70 weight %, therefore, in order to mix both equably, the kind and the blending ratio of thermoplastic resin and hydrated metal compound are adjusted into the suitableeest, so that the heat that shearing produced of resin when mixing carries out fusion, and mix fully with hydrated metal compound.And, in order to adjust the melt-flow physical property of intermediate,, make it mobile and become one so that the intermediate of pulverizing is heated, compress, mix the thermoplastic resin more than 2 kinds sometimes.For example, in order to adjust the flowability of thermoplastic resin, mixed rubber sometimes.
It is fashionable that the composition of the hydrated metal compound of thermoplastic resin and high combined amount is rubd, and rubs equably when can utilize the pressurization kneader to shear and close, and still, utilizes other mixers, then once can't rub and close evenly., uneven stirring thing can be pulverized for this reason, and it is restored to mixer repeats to rub and close, thereby obtain almost stirring uniformly thing.
And in the resin of composite blank and painted composite blank, though add hydrated metal compound (the 1st filler), the moisture in these compounds is decomposed through heating, can make marble have flame retardancy or noninflammability.Especially, use the hydrated metal compound of 85～75 weight %, then can obtain the noninflammability synthetic marble at the thermoplastic resin of 15～25 weight %.
And, can also add calcium carbonate.In order to make synthetic marble have sterilization, bacteria-eliminating efficacy, can also add silver nano-grain, titanium particle, contain Ag as the 2nd filler
+Zeolite granular.In the present invention, though colouring agent and the 2nd filler directly can be mixed with resin and the 1st filler,, added with master batch form, more help improving the dispersiveness of pigment and the 2nd filler.
The amount of the 1st filler has no particular limits.Confirm through the present inventor, add the 1st above filler of 70 whole weight %, still can the manufacture of intraocular marble.The 2nd filler can mix obtaining necessary sterilization and the required amount of bacteria-eliminating efficacy in batches, and its addition is 100～10000ppm when adding silver nano-grain, preferred 100～1000ppm.
Resin as composite blank and painted composite blank, can use the natural decomposition plastics, for example poly lactic acid series natural decomposition plastics, aliphatic polyamides are the natural decomposition plastics, can soften other known natural decomposition plastics of fusion through heating.
Especially, when using poly lactic acid series natural decomposition plastics, it is then softening to heat these poly lactic acid series natural decomposition plastics, cause adhesiveness to increase, thereby be difficult to use the cylinder of heating to be processed, but add and the mixing hydrated metal compound to softening poly lactic acid series natural decomposition plastics, then can reduce the adhesiveness of natural decomposition plastics, therefore can be processed into shape arbitrarily.
Importantly, the resin of composite blank and painted composite blank and hydrated metal compound or colouring agent are used with minute form of shape composition, and carry out fusion when mixer is sheared, rub and close.The use amount of hydrated metal compound is 85～60 weight %, greater than thermoplastic resin, is because simple mixer, resin and hydrated metal compound can't be rubd and close.
Crushing operation can use known disintegrating machine.Pressurized operation comparatively it is desirable to, and uses press molding molding box and press molding forcing press, carries out the squash type pressurization in molding box.In addition, intermediate to the extruding of heating shaping molding box, is made its fusion, when flowing, enters if any air, can become the reason of breaking etc.Therefore, comparatively it is desirable to, intermediate soften become to a certain degree after, open a little forcing press deflates.
When forming the speckle apperance of painted intermediate, utilize the colouring agent of light colour to form after the speckle apperance of light colour earlier, add again and the identical and denseer colouring agent of the color of above-mentioned colouring agent than the color of above-mentioned colouring agent, form dark speckle apperance, thereby the color in the mobile apperance of reproduction synthetic marble is dense shallow.
Painted intermediate can also be rubd after the synthetic uniform color, is cured and obtains painted composite blank, then should pulverize and make by painted composite blank.
And, the whole surface of basic intermediate or painted intermediate or a part of surface are carried out painted, make the 1st or the 2nd surface colour intermediate, then can around the mobile apperance of synthetic marble, form coloured border.
The shape of basis intermediate, the 1st, the 2nd surface colour intermediate and painted intermediate, though it is without particular limitation, but,, can form and corresponding point-like of the volume of above-mentioned intermediate or the mobile apperance of island shape if adopt graininess, laminar, block.
Add single or a plurality of different colouring agents to basic intermediate, and it is mixed into the speckle apperance, then can around the mobile apperance that forms by basic intermediate, form the border of single color or multiple color.
