Embodiment 1

[0040] Accurately weigh the wood-plastic particles A, B and C according to the ratio of 6:3:1, put them into the mixer and stir them evenly, and then extrude them through the special-shaped conical twin-screw extruder to process the plastic Wood grain planks.

Embodiment 2

[0042] Accurately weigh the wood-plastic particle A, wood-plastic particle B and wood-plastic particle C according to the ratio of 5:2:3, put them into the mixer and stir evenly, and then extrude them through the special-shaped conical twin-screw extruder to process the plastic Wood grain planks.

Embodiment 3

[0044] Accurately weigh the wood-plastic particle A, wood-plastic particle B and wood-plastic particle C according to the ratio of 9:6:5, put them into the mixer and stir them evenly, and then extrude them through the special-shaped conical twin-screw extruder to process the plastic Wood grain planks.

[0045] In the extrusion process of the above embodiment, special attention should be paid to the precise control of the temperature and speed ratio of the machine to achieve a better wood grain effect. The formed board is cut after water cooling, and then polished by a sander or directly removed. After deburring, put into storage.

[0046] The plastic-wood wood-grain panels formed in the above three examples are tested according to the GB / T17657-1999 standard, and the highest values ​​of the main physical properties are as follows: density 1.25 grams per cubic centimeter, 24-hour water absorption 0.1%, Rockwell hardness 90HRR, static bending strength 37.5MPa, modulus of elasti...

Abstract

The invention discloses a plastic wood grain sheet and a processing method thereof. Present sheets having a wood grain effect mainly comprise a composite sheet, a wood sheet and a PVC sheet, and have the disadvantages of harmfulness to human bodies, environmental pollution, consumption of a large amount of forest resources, and benefiting for the sustainable development of the environment. The plastic wood grain sheet comprises 50-70 parts of a fused vegetable fiber, 20-30 parts of a plastic, 1-2 parts of a lubricant, 3-4 parts of a compatilizer, 1-2 parts of a color master batch material and 1-4 parts of an additive. The plastic wood grain sheet has a natural wood grain effect, plastics can use the wax paper of waste wires and cables, waste beverage bottles or plastic bags and the like, the vegetable fiber can use waste wood chips, bamboo chips and the like of a timber processing factory, and the recycle of waste materials can save a large amount of natural resources comprising the forest and the like; and the processing method has the advantages of no need of a gellant, and mitigation of the harms of the formaldehyde component to human bodies and the environment.

Description

【Technical field】 [0001] The invention relates to the field of boards, in particular to a formula and a processing method of plastic wood boards. 【Background technique】 [0002] Building panels are widely used in wall panels, ceilings, decorative panels, guardrails, outdoor leisure tables and chairs, indoor and outdoor floors, etc. The existing boards with wood grain effect mainly include composite boards, solid wood boards and PVC boards, but these existing boards with wood grain effects are not only harmful to the human body, pollute the environment, but also consume a large amount of forest resources. Not conducive to the sustainable development of the environment. 【Content of invention】 [0003] According to the problems mentioned in the background technology, the present invention provides a wood-plastic wood-grain board and its processing method. After adjusting and optimizing the formula and improving the processing technology, the produced wood-plastic wood-grain ...
