Problems solved by technology

[0003] In recent years, with the continuous increase in the production of bamboo products, the leftovers, leftovers, and bamboo tips of bamboo processing enterprises have not been utilized. Except for a very small part that is used to produce bamboo chopsticks, most of them cannot be processed. These "three wastes" Either used as fuel, or discarded everywhere, not only the utilization rate of resources is less than 50%, the waste of resources is large, and new pollution is formed

Embodiment 1

[0030] Step 1: put the bamboo into a mill to grind into bamboo fibers, and obtain 4-mesh particles after sieving, and then dry them in an oven at 110°C for 24 hours to keep the average moisture content of the bamboo fibers at 5%;

[0031] Step 2: Put 40 parts of dried bamboo powder into a high-speed mixing mixer, and spray 2 parts of prepared aluminate coupling agent solution while stirring until the bamboo powder is fully and evenly infiltrated by the coupling agent solution, then take it out.

[0032] Step 3: Mix the treated bamboo powder, PP plastic granules, and reinforcing agent according to the ratio of 40, 50, and 0.3 parts by weight, and put them in a high-speed mixing mixer for high-speed stirring at a stirring speed of 2000r / min for 15 minutes.

[0033] Step 4: Mix the lubricant polyethylene wax and the composite lubricant Opka-100 in a mass ratio of 1:1, add to the raw materials mixed in step 3, the amount of lubricant added is 2 parts, and stir at high speed after ...

Embodiment 2

[0040] The difference from Implementation 1 is that the ratio of the two lubricants is different, polyethylene wax and composite lubricant Opka-100=1:3; namely:

[0041] Step 4: Mix polyethylene wax with composite lubricant Opka-100 in a mass ratio of 1:3, and then take

[0042] Add 3 parts to the raw materials mixed in step 3, stir at high speed for 15 minutes, and then pave the mixture into a slab of 400mm×400mm.

[0043] Refer to the standard GB / T17657-2013 (Test methods for physical and chemical properties of wood-based panels and decorative wood-based panels), test the physical and mechanical properties of bamboo powder / PP wood-plastic reinforced wall panels. The result is as follows:

[0044] Shore hardness: 87.67HA Bending strength: 47.88MPa, elastic modulus: 2908.60Pa, tensile strength: 17.56MPa, Charpy impact strength: 13.55KJ / m2; 24-hour water absorption: 0.87%.

Embodiment 3

[0046] The difference from Example 2 is that

[0047] The difference from Implementation 1 is that the ratio of the two lubricants is different, polyethylene wax and composite lubricant = 3:1; that is

[0048] Step 4: Mix polyethylene wax and compound lubricant at a ratio of 3:1, take 1.5 parts and add it to the raw materials mixed in step 3, stir at high speed for 15 minutes, and then pave the mixture into a 400mm×400mm board Blank.

[0049] Refer to the standard GB / T17657-2013 (Test methods for physical and chemical properties of wood-based panels and decorative wood-based panels), test the physical and mechanical properties of bamboo powder / PP wood-plastic reinforced wall panels. The result is as follows:

[0050] Shore hardness: 82.54HA Bending strength: 40.78MPa, elastic modulus: 2678.90Pa, tensile strength: 15.20MPa, Charpy impact strength: 10.78KJ / m2; 24-hour water absorption: 0.91%.

Abstract

A bamboo powder / PP(propene polymer) wood-plastic reinforced wall board is characterized by comprising, by weight, 30-45 parts of bamboo fibers, 40-50 parts of PP plastic, 2-4 parts of coupling agent, 2-5 parts of lubricating agent and 0.2-0.8 part of reinforcing agent. A processing method includes the steps of pretreatment, material stirring, mat formation, hot-press curing, drying, maintaining and the like. The wood-plastic reinforced wall board prepared according to the processing method has low water absorption and high mechanical property, is better than wall boards with the same specification in the market, and is simple in process, low in production cost and widely applied to construction industry, thereby having good market prospect.

Description

technical field [0001] The invention relates to the technical field of wood-based panels, in particular to a bamboo powder / PP wood-plastic reinforced wallboard and a processing method thereof. Background technique [0002] Wood-plastic panel is a new type of environmentally friendly composite material product. It has been developed rapidly in recent years. Wood, crop straw, bamboo, etc. are the main raw materials. However, China's forest resources are limited, so it is necessary to seek new materials and new energy sources to replace wood powder. Wood-plastic composite materials can not only save forest resources, but also provide new materials for the preparation of wood-plastic composite materials. [0003] In recent years, with the continuous increase in the production of bamboo products, the leftovers, leftovers, and bamboo tips of bamboo processing enterprises have not been utilized. Except for a very small part that is used to produce bamboo chopsticks, most of them ca...
