Embodiment 1
[0024] The application of the special-shaped aggregate of the present invention to the preparation method of artificial granite includes the following process steps:
[0025] 1 After the calcium carbonate powder sand (or other functional powder sand) and the pigment are evenly mixed in the mixer, add the adhesive to which an appropriate amount of initiator and curing agent have been added and stir into a sticky block.
[0026] 2 Put the stirred mixture into a mold and press it under vacuum conditions, and cure it at room temperature for 4-6 hours, then release the mold and cure it for 5 hours to obtain special-shaped aggregates.
[0027] 3 The special-shaped aggregate obtained in step 2 is optimized according to the material detection method to make artificial granite.
[0028] The special-shaped aggregate is applied to the preparation method of artificial granite in all technical schemes. The preferred step ① The adhesive is unsaturated polyester tree, and the addition amount is 5%-8%...

[0041] ① Preparation method of light blue fluorescent sphere shaped aggregate, the sphere diameter is 1cm. The specific preparation process is:
[0042] Weigh 5kg of calcium carbonate powder (300 mesh and below), 0.05g of ultramarine blue and 20g of blue phosphor in a vertical mixer, stir at 40r / min for 5-8min; when the calcium powder and pigment are almost fully stirred, weigh Take 550g of unsaturated resin, add 1.65g of cobalt naphthenate into the resin and stir well, then add 7.7g of methyl ethyl ketone peroxide and stir well; add the treated unsaturated resin to the calcium powder until the calcium powder and resin become Moist dough-like.
[0043] Fill the stirred material into the spherical mold, vacuumize the filled mold press to -0.098, and press for 5-10 minutes. After pressing, take out the blue spherical shaped aggregate from the mold;
[0044] The prepared blue fluorescent sphere shaped aggregate is placed on a clean flat plate and spread out for room temperature curing...

[0050] ① Preparation method of yellow fluorescent transparent ellipsoid shaped aggregate. The specific preparation method is:
[0051] Weigh 5kg of aluminum hydroxide powder (300 mesh) and 20g of yellow phosphor in a vertical mixer, stir at 40r / min for 5-8min; when the calcium powder and phosphor are almost fully stirred, weigh 550g of unsaturated resin, Add 1.65g of cobalt naphthenate into the resin and stir well, then add 7.7g of methyl ethyl ketone peroxide and stir well; add the processed unsaturated resin to the aluminum powder until the aluminum powder and the resin become a wet dough.
[0052] Fill the stirred material into the ellipsoid mold, vacuumize the filled mold press to -0.098, and press for 5-10 minutes. After pressing, the transparent ellipsoid special-shaped aggregate can be taken out from the mold;
[0053] The prepared blue fluorescent sphere shaped aggregate is placed on a clean flat plate and spread out for room temperature curing.
[0054] ②The preparation meth...
