The invention discloses a production process of a novel environment-friendly plastic building template. The production process comprises the steps of preparation of an A-layer material, preparation of a B-layer material, preparation of a C-layer material, die pressing, cooling shaping, die cutting and finished product conveying, wherein the preparation of the A-layer material, the preparation of the B-layer material and the preparation of the C-layer material respectively comprise material mixing, feeding and mixing modification; and the specific steps are as follows: S1, the preparation of the A-layer material: a, material mixing: feeding a recycled crushed material, PP1, PP2 and an auxiliary agent mixture to a material storage barrel through a vacuum material suction system according to a formula ratio, discharging materials to a material mixing bin according to the formula ratio through a weighing mixer, carrying out mixing and stirring at a high speed in the material mixing bin to form an A-layer mixture, and then discharging the A-layer mixture to a main machine material storage barrel. The production process of the novel environment-friendly plastic building template has the main beneficial effects that the matching accuracy is high, the labor waste is avoided, the cost is saved, the working efficiency is high, the wear resistance, the temperature resistance, the weather resistance and the chemical resistance are achieved, and energy conservation, environmental protection and emission reduction are achieved.
