Problems solved by technology

However, the currently produced wood-plastic panels are generally divided into two categories, one is solid panels, which are bulky, inconvenient to transport and install, and prone to defects such as bending and deformation when suspended in the air; the other is foamed plastic-wood panels , this type of board has a lower overall density and lighter weight, but its surface microporous structure is easy to absorb dust, often the surface needs to be covered with a film, and the bearing capacity is low, and most of them use polyvinyl chloride matrix, polyvinyl chloride in the long-term It is easy to age, change color and even release toxic gas during use

Embodiment 1

[0040] Embodiment 1: A kind of preparation method of honeycomb structure wood-plastic composite board, its preparation process is:

[0041] (1) Mix the wood flour and isocyanate that have been vacuum-dried at 100°C for 5 hours to constant weight in a small high-speed mixer for 20 minutes, then add stearic acid and continue mixing for 20 minutes at 100°C, the mass ratio of wood flour:stearic acid:isocyanate For 100:6:4, obtain 120 mesh modified wood flour;

[0042] (2) After blending polypropylene, modified wood powder, EPDM, and antifungal agent, extrude and granulate to form wood-plastic composite material particles. The temperature of the extrusion barrel is 190°C, and the temperature of the die is 190°C;

[0043] (3) Lay plastic-wood composite material particles at the bottom of the mold cavity, pressurize it into a 4mm thick plate;

[0044] (4) Take the FRP grating whose length and width are both smaller than the length and width of the mold cavity, and use the plate pres...

Embodiment 2

[0048] Embodiment 2: a kind of preparation method of honeycomb structure wood-plastic composite board, its preparation process is:

[0049] (1) Mix wood flour and isocyanate, which have been vacuum-dried at 100°C for 5 hours to constant weight, in a small high-speed mixer for 10 minutes, then add stearic acid and continue mixing for 10 minutes at 100°C, the mass ratio of wood flour:stearic acid:isocyanate For 100:5:3, obtain 40 mesh modified wood flour;

Abstract

A honeycombed plastic wood composite material sheet is formed by a plastic wood composite material outer cladding layer, a glass steel grating and a porous core material, the glass steel grating is filled with the porous core material, and the periphery of the glass steel grating is provided with the plastic wood composite material outer cladding layer. A making method of the sheet comprises the following steps: modifying wood powder; extruding the modified powder, and granulating to obtain plastic wood particles; carrying out mold pressing, and cutting to form a sealing plate; laying the plastic wood plastics, the sealing plate and the glass steel grating; foaming the core material in the glass steel grating; covering the grating with the sealing plate, and filling with the plastic wood plastics; and carrying out mold pressing. The method has the advantages of convenient production and low production cost. Compared with solid plastic wood sheets, the sheet disclosed in the invention has the advantages of small use amount of the plastic, environmental protection, low and flexibly adjustable density, light weight and creep resistance; and compared with traditional foamed plastic wood sheets, the sheet disclosed in the invention has the advantages of small use amount of plastic wood, large rigidity, high modulus, no surface coating, no dust adsorption, and realization of convenient adjustment of the density.

Description

technical field [0001] The invention discloses a composite material board, in particular to a plastic-wood composite board with a honeycomb structure and a production method thereof. Background technique [0002] In recent years, the research and application of wood-plastic composite materials have received high attention. It has excellent anti-corrosion, waterproof, crack-proof and anti-fouling properties, no secondary processing, easy installation, no toxic chemical components, low-carbon environmental protection, It does not need to be painted, polished, easy to maintain, and easier to clean, so it can be widely used in various occasions such as indoor and outdoor decoration, garden engineering construction, workshop anti-corrosion engineering, marine anti-corrosion engineering, sanitation facilities, etc. It can be used as pallets, packing boxes and other packaging Materials, storage materials such as planks and beams, decoration and decoration materials such as houses, ...
