Abstract

The invention relates to a wood / plastic composite floor board production process and belongs to the field of wood / plastic composite floor board processing. The production process includes the first step of carrying out drying and ungrease treatment on small wood angle materials, straw and other things and then carrying out smashing to enable the fineness degree to reach 70-100 meshes, the second step of getting and mixing fine powder raw materials, PVC, light calcium carbonate, calcium stearate, PVC processing agents, PVC foaming agents, PVC tensile modifying agents, compound stabilizers, plastic filling agents, soda, PE wax, stearic acid and PVC foaming modifiers at a high speed, wherein the mixing temperature is 100 DEG C to 130 DEG C, the rotation speed for mixing is 700 rounds per minute, the mixing time is 25 to 35 minutes, and the feeding speed of equipment is 100 to 800 rounds per minute, the third step of carrying out high-temperature extruding and forming on obtained wood / plastic mixed powder through a double-screw extruder and a shaping die, and making the wood / plastic mixed powder into basic plates, and the fourth step of enabling male grooves and female grooves to be cut in four faces of the basic plates through a double-end milling device, and carrying out printing on the basic plates through coating and curing process to form finished wood / plastic composite floor boards. The finished wood / plastic composite floor boards are friendly to environment, waterproof, resistant to corrosion, capable of preventing insects, high in mildew resistance, good in flame retarding performance, strong in moisture retention and convenient to install.

Description

technical field [0001] The invention relates to a wood-plastic composite floor production process, which belongs to the field of wood-plastic composite floor processing. Background technique [0002] Wood-plastic composite board is a kind of wood (wood cellulose, plant cellulose) as the base material, thermoplastic polymer material (plastic) and processing aids, etc., which are mixed evenly and then heated and extruded by mold equipment. The high-tech green environmental protection material has both the performance and characteristics of wood and plastic, and can replace wood and plastic as a new environmentally friendly high-tech material. Wood-plastic composite board is widely accepted by people for its good strength, high hardness, small rebound after water absorption, corrosion resistance, and recyclability. It is an ideal material to replace wooden flooring for household use. Mainly used in building materials, furniture, logistics packaging and other industries. The w...
