The stabilizer is a BS-105 rare earth composite heat stabilizer.
The titanium dioxide is R6628 titanium dioxide.
The diatomite superfine powder is prepared by grinding diatomite into 2500-mesh diatomite superfine powder by a superfine tire vertical mill (also called superfine roller mill), wherein the chemical component of the diatomite is SiO 2 (92.54%)、Fe 2 O 3 (1.54%)、Al 2 O 3 (3.38%) and others (2.54%).
The dust mud kiln slag superfine powder is prepared by grinding dust mud kiln slag into 2500-mesh dust mud kiln slag superfine powder through a superfine tire vertical mill (also called superfine roller mill), and the chemical component of the dust mud kiln slag is Fe 2 O 3 (32.25%)、SiO 2 (19.83%)、CaO(16.41%)、Al 2 O 3 (11.28%)、MgO(3.82%)、Na 2 O(2.81%)、ZnO(2.70%)、MnO(2.42%)、TiO 2 (1.34%)、K 2 O (0.67%) and others (6.47%).

And then the solid waste base PVC flame-retardant wood grain film precursor is hot-pressed for 15-20 min on a hydraulic flat press at 180-200 ℃ to obtain the solid waste base PVC flame-retardant wood grain film.
The innovation points of the invention are as follows:
(1) the superfine tyre vertical mill (also called superfine roller mill) uses motor to drive speed reducer to drive grinding disc to rotate, the material to be ground is fed into the centre of rotary grinding disc by means of air-locking feeding equipment, and under the action of centrifugal force the material can be moved toward the periphery of grinding disc, and fed into grinding roller table. Under the action of the roller pressure, the material is crushed by the extrusion, grinding and shearing actions. Meanwhile, air is uniformly sprayed upwards at a high speed from an air ring surrounding a grinding disc, the ground materials are blown up by a high-speed air flow at the air ring, the materials with coarser granularity are blown back to the grinding disc to be ground again, fine powder is brought into a grading machine by the air to be graded, qualified fine powder flows out of the grinding machine along with the same air, the fine powder is collected by a grading system (patent No. ZL201030143470.6) of secondary air separation to be a product, unqualified coarse powder falls on the grinding disc again under the action of blades of the grading machine and is ground again together with a newly fed material (patent No. ZL200820113450.1), and the circulation is carried out to obtain the superfine materials with the particle size of 3-10 mu m.

Not only breaks through the technical barrier that the powder ground by a common tire vertical mill (also called common roller milling) can only reach the fineness of 400, but also solves the technical problem that the ball-milled powder only forms a spherical appearance and does not have fiber characteristics. Wherein the common diatomite is spherical, and is ground into gravel (such as prismatic, sub-prismatic and sub-circular) by an ultrafine tire vertical mill (also called ultrafine roller grinding), and can replace ultrafine powder of needle-shaped wollastonite, so that the mechanical property is further improved.
