Problems solved by technology

However, the formula material is not stable, and the lubricating effect of paraffin wax is not very good, which will accelerate the wear of the extrusion machine during the later extrusion. Bamboo powder is easy to mold, which greatly reduces the practical life of outdoor plastic wood, and there will be material purchases. Difficult, complicated and other problems will reduce production efficiency

Embodiment 1

[0017] Take 50g of sawing powder, 25g of PE plastic particles, 4g of compatibilizer, 15g of calcite powder, 5g of talc powder, and 1g of lubricant, and carry out mixing, extruding by extruder, discharging cooling, cutting, and collecting finished products to obtain plastic wood moldings. The mixing method is as follows: Turn on the heater, mix 50g of sawdust and 25g of PE plastic particles evenly, then heat up to 150°C for drying, and then cool to 115°C after drying. Drain and steam until the water vapor in the wood flour is exhausted. Slowly lower the temperature during cooling and stir during the cooling to cool the mixture evenly. After drying and cooling to 115°C, add phase

[0018] Compatible agent 4g, calcite powder 15g, talc powder 5g, lubricant 1g, stir evenly, the temperature during stirring should not be higher than 120 degrees, otherwise the additives and plastics will stick and agglomerate, resulting in waste of raw materials.

[0019] Example 1:

[0020] Take 60...

Abstract

A plastic wood granulation formula is characterized by comprising, in weight percent, 45-65% of wood flour, 10-30% of PE (polyethylene) plastic particles, 2-5% of compatibilizers, 8-15% of calcite powder, 2-8% of talcum powder and 0.4-2% of lubricating agents. According to the formula, kinds of used raw materials are less, additives are less, waste materials are changed into things of value, costis low, production cost is reduced to a large extent, and a produced plastic wood material meets environment-friendly and energy-saving requirements.

Description

technical field [0001] The present invention relates to the technical field of a new material, more specifically to the technical field of a plastic wood material. Background technique [0002] With the depletion of global resources and the increasing awareness of social environmental protection, higher requirements are placed on the application of wood and petrochemical products. In this context, plastic wood composite materials have been gradually promoted and applied by many countries in the world today as green and environmentally friendly new materials. In China, plastic wood material is a very young emerging environmental protection industry, which has been in a period of rapid development since 2005. Plastic wood composites are also used in a wider range of applications, including window and door products, thermal insulation systems, park benches, flower sheds and solar screens for tower buildings. The formula of traditional plastic wood materials is to use raw mate...
