Problems solved by technology

However, the current wood-plastic materials are based on the use of wood fibers, which are easy to tangle and difficult to pave. The process of crushing wood or waste paper into wood powder and then compounding it with plastic is often used. Mixing and extrusion processing, but the energy consumption is large, the mechanical strength is small, and wood powder is needed, which increases the cost and energy consumption of crushed wood powder, and the prepared extruded wood-plastic has low mechanical strength, poor comprehensive performance, and is not resistant to aging
There are also some significant disadvantages, such as poor compatibility with hydrophilic resins, instability at high temperatures, hygroscopicity, and great restrictions on the thickness and size of wood-plastic processing, and the existing wood-plastic materials Most of them are not corrosion resistant, not flame retardant

Embodiment 1

[0019] A method for preparing a flame-retardant wood-plastic wallboard, comprising the following steps:

[0020](1) Flame surface treatment: Treat the surface of the loose sheet with the blue flame of methane for 3 times, and the flame temperature is controlled at 1000°C, so that the flame surface of the sheet is smooth and deburred to form a treatment layer. The treatment layer is located on the outermost surface and has a lot of looseness (2) Washing: Spray the surface of the treatment layer with 7% dilute acid in the form of a spray, and keep the treatment layer facing up, and let it stand for 1 (3) Wetting: use 0.7% sodium α-olefin sulfonate solution in the form of spray to spray on the surface of the treatment layer of the board, and keep the treatment layer facing up, Let it stand for 0.5 hours to wet the surface of the board; (4) Diffusion treatment: add 1.3 parts of sodium dodecylbenzenesulfonate to 100 parts of alcohol solution with a mass fraction of 17% boron triflu...

Embodiment 2

[0028] A method for preparing a flame-retardant wood-plastic wallboard, comprising the following steps:

[0029] (1) Flame surface treatment: use methane blue flame to treat the surface of the loose plate 6 times, and the flame temperature is controlled at 1400°C, so that the flame surface of the plate is smooth and deburred to form a treatment layer. The treatment layer is located on the outermost surface and has a lot of porosity (2) Washing: Spray the surface of the plate treatment layer with 5% dilute acid in the form of a spray, and keep the treatment layer facing up, and let it stand for 0.5 hours , so that dilute acid penetrates into the interior of the board; (3) Wetting: Spray the surface of the treatment layer of the board with a 0.5% sodium α-olefin sulfonate solution in the form of a spray, and keep the treatment layer upward, statically Set aside for 0.1 hour to wet the surface of the board; (4) Diffusion treatment: Add 1.1 parts of sodium dodecylbenzenesulfonate ...

Abstract

The invention discloses a preparation method of a flame-retardant wood-plastic wallboard. The invention belongs to the technical field of wood-plastic processing, the prepared wallboard is nailable, drillable, cuttable, bondable, and can be connected and fixed by a connecting piece, and the wood-plastic wallboard has much better physical properties than that of logs, has better dimensional stability than that of wood, no cracking or warping is caused, no wood knurl or twills are generated, the wallboard can be made into various colorful products, and regular maintenance is not needed; the wood-plastic wallboard has the excellent properties of fire resistance, water resistance, corrosion resistance, moisture resistance, worm resistance, fungus resistance, acid and alkali resistance, is harmless, and is low in maintenance cost; no pollution is caused; the wood-plastic wallboard has a wood-like appearance in use, and is higher in hardness, longer in service life, better in toughness, higher in strength and energy-saving compared with log. The product has the advantages of hard quality, light weight, heat preservation, smooth and flat surface and pollution free performance.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic processing, in particular to a method for preparing a flame-retardant wood-plastic wallboard. Background technique [0002] The introduction of wood-plastic wall panels is a milestone in the home improvement industry. Wood-plastic wall panels are widely used indoors, and can be used in all three-dimensional spaces except the ground. It can be completed at one time, which greatly shortens the time for home decoration and saves a lot of labor costs. The wood-plastic wallboard completely makes the interior decoration say goodbye to the use of paint and other harmful materials to the human body, and makes the home decoration achieve a true sense of environmental protection. It is also the product of choice in the home improvement market. The cement exterior wall hanging board is used as interior and exterior wall decoration materials. Mainly used for facade decoration and transformation of vil...
