Abstract

The invention relates to the technical field of plastic-wood floor production, in particular to a manufacturing process of particle wood flour for plastic-wood floor production, the particle wood flour is prepared from, by weight, 25-30 parts of sawdust wood shavings, 30-35 parts of straw, 7-9 parts of flame retardant, 5-8 parts of coupling agent and 12-16 parts of filler, and the manufacturing process comprises the following steps that S1, the raw materials are weighed according to the weight for standby application; s2, adding the sawdust, the wood shavings and the straws into a mixing kettle, sequentially adding the filler, the coupling agent and the flame retardant, and mixing and stirring to obtain a product A; and S3, the product A is placed in a rotary drum of drying equipment to be electrically heated, and a product B is taken out 15-20 minutes later and placed in a dry place. According to the invention, the compatibility of the fiber and the filler is improved, the water content of the product can be reduced, and the flame retardant property and heat resistance of the particle wood powder can be improved.

Description

technical field [0001] The invention relates to the technical field of plastic wood floor production, in particular to a manufacturing process of particle wood powder for plastic wood floor production. Background technique [0002] The formula of wood powder and plastic is the core technology in wood-plastic processing technology, and its quality will directly affect the processing technology and product quality of the product. WPC formula is generally composed of plastic, wood powder and various additives, and its ratio varies with different processing equipment, and also varies with different uses and requirements of the product. Before processing, put wood flour, plastics and additives in a high-speed mixer according to the formula ratio for mixing, mainly to make several raw materials and additives evenly mixed, and prepare for extrusion production or compression injection. [0003] In the manufacturing process of wood powder, it is easy to cause the moisture content of...
