The square flame-retardant luminous artificial stone according to claim 1, wherein the fluorescent particles are solids formed by one or a mixture of more of fluorescent ceramic particles, fluorescent glass, fluorescent silica particles and fluorescent plastics; the particle size distribution of the fluorescent particles is 5-20 mm.
9. The square flame-retardant luminous artificial stone according to claim 1, wherein the aqueous polymer emulsion is one or more of a styrene-based emulsion, an acrylate emulsion, a vinyl acetate emulsion and an ethylene-vinyl acetate copolymer emulsion.
10. The production process of the square flame-retardant noctilucent artificial stone according to any one of claims 1-9, which comprises the following steps:
(1) weighing inorganic adhesive, auxiliary agent, filler, pigment and fluorescent particle material according to the material proportion, adding the raw materials into a main stirrer by using a conveyor belt, uniformly stirring, adding the weighed aqueous polymer emulsion, continuously stirring, and closing a top door of the stirrer after the materials are stirred into a large cluster of 30-40 cm;
(2) vacuumizing and distributing materials, starting a vacuumizing device to enable the vacuum degree of a vacuum chamber to be below-0.06 MPa, and uniformly dispersing the agglomerated materials in the step (1) in a mold, wherein the size of the mold is 2.70 multiplied by 1.80 multiplied by 1.25 m;
(3) pressing and forming, namely pressing the material in the die by using a pressure head, wherein the pressure of the pressure head is over 12MPa, and the material sequentially passes through low-speed swinging for 60s, low-speed vibrating for 120s, high-speed swinging for 120s and high-speed vibrating for 60 s;
(4) after the pressing of the rough blocks is finished for 4-8h, adding water into the die to submerge the surface of the rough blocks by 3-5cm, and carrying out primary maintenance;
(5) after curing and hardening, demolding the pressed material obtained in the step (4), putting the demolded material into a steam curing system, and curing for 24-36h, wherein the temperature in a steam chamber is controlled to be 55-65 ℃, so as to obtain a raw material of the noctilucent artificial stone;
(6) cutting and surface treatment, cutting the rough material into plates with the thickness of 20mm, 25mm, 30mm or 50mm according to the static pressure of the rough material, polishing, and packaging in grades to obtain the square flame-retardant noctilucent artificial stone.
