Abstract

The invention relates to production equipment and a production process for a novel multicolour wood-plastic composite material. The production equipment comprises a rack, a main motor, a screw, a machine barrel, a vacuumizing device, a main feeding device and an auxiliary feeding device, wherein the screw is composed of a conical section and a cylindrical section, and the cylindrical section is arranged at a shallow spiral groove of the conical section. The production process comprises the steps of preheating the machine barrel and a die, adding light-colour wood-plastic composite material particles, regulating a speed, starting a vacuum pump, adding dark-colour colour master batches, and forming. The equipment disclosed by the invention is high in extrusion pressure, and is a conical single-screw extruder provided with the main feeding device, the auxiliary feeding device and the vacuumizing device, which is reasonable in extrusion speed, free from bubbles and bulges, used for producing a high-wood-flour-content multicolour wood-plastic composite material, and accurate and efficient in process.

Description

technical field [0001] The invention relates to a production equipment and a production process of a wood-plastic composite material, in particular to a production equipment and a production process of a colorful wood-plastic composite material. Background technique [0002] The traditional wood-plastic composite materials have the same color throughout and no color. The development of multi-color wood-plastic composite materials has become one of the research hotspots. The traditional single-screw extruder has no vacuum device, no main feeding device, and is prone to bubbles, bulges and other problems. It is produced by low-speed extrusion, with low extrusion pressure and low efficiency, and has been eliminated by the industry. Existing multi-color wood-plastic composite materials are mainly produced by conical twin-screw extruders, and dark-color masterbatches are added to light-color wood-plastic particles to obtain multi-color wood-plastic composite materials. The main ...
