Embodiment 2

[0045] A preparation method for a wooden composite door, comprising the steps of:

[0046] Step 1: Crush walnut and cherry wood into small pieces with a diameter of 20mm, and then grind them into 90-mesh wood powder. The wood powder is dried at 150°C for 5 hours, and the water content is controlled at 2% for later use. Fraxinus mandshurica, rosewood and oak wood Wood, kiln-dried, control the moisture content to 13%, and eliminate defects;

[0047] The second step: take by weighing 100 parts of walnut wood powder, 0.25 parts of octadecanoic acid, 10 parts of phenolic fiber, 6 parts of magnesium oxide powder, 5 parts of insect repellent quick-killing and 10 parts of potassium silicate according to the ratio of parts by mass. 5 parts of oxidized polyethylene, 12.5 parts of silane coupling agent KH-570, 12 parts of silane coupling agent KH-560, 10 parts of butyl stearate, 100 parts of HDPE, 90 parts of cherry wood powder, 3 parts of LDPE , 3 parts of chlorinated polyethylene, 5 p...

Embodiment 3

[0060] A preparation method for a wooden composite door, comprising the steps of:

[0061] Step 1: Crush walnut and cherry wood into small pieces with a diameter of 10mm, and then grind them into 80-mesh wood powder. The wood powder is dried at 140°C for 4 hours, and the water content is controlled at 2% for later use. Fraxinus mandshurica, rosewood and oak wood Wood, kiln-dried, control the moisture content to 12%, and eliminate defects;

[0062] Step 2: Weigh 100 parts of walnut wood powder, 0.15 parts of stearic acid, 8 parts of phenolic fiber, 4 parts of flame retardant FRC-6, 3 parts of insect repellent Mibaca, potassium 8 parts of water glass, 3 parts of oxidized polyethylene, 10.5 parts of silane coupling agent KH-570, 10 parts of silane coupling agent KH-560, 5 parts of butyl stearate, 80 parts of HDPE, 80 parts of cherry wood powder , 2 parts of LDPE, 2 parts of chlorinated polyethylene, 4 parts of borax, 2.5 parts of light calcium carbonate, 3 parts of dimethyl meth...

Abstract

The invention discloses a wooden composite door preparation method, wherein Fraxinus mandshurica Rupr, a walnut wood-plastic composite sheet material, Ormosia henryi, a cherrywood wood-plastic composite sheet material and oak are sequentially subjected to glue coating stacking pressing, and the obtained material is coated with an inner layer coating material and an outer layer coating material toprepare the wooden composite door. According to the present invention, the prepared wooden composite door does not contain formaldehyde; and compared with the conventional composite door, the preparedwooden composite door of the present invention has the following characteristics that the tensile strength is increased by 50-70%, the flexural strength is increased by 40-50%, the flexural modulus is increased by 45-55%, the bearing force is increased by 40-60%, the high-low temperature notched impact strength is increased by 50-60%, the oxygen index is increased by 40-50%, the heat distortion temperature is increased by 25-35%, the two-way anti-warping ability is high, the sound absorption effect is good, the sound insulation performance is good, the heat absorption effect is good, the overall mass is reduced by 15-25%, the toughness is good, the mechanical property is good, the bending stress is high, the internal stress is low, the insect control effect is good, the bidirectional drydeformation is low, the elongation at break is increased by 5-25%, insect pests are avoided, and the product further has advantages of corrosion resistance, moisture resistance, high hardness and goodcold resistance.

Description

technical field [0001] The invention relates to the technical field of wooden doors, in particular to a preparation method of a wooden composite door. Background technique [0002] Solid wood composite door refers to a solid or close to solid body made of wood, glued wood, etc. as the main material, and the surface layer is a door with wooden veneer veneer or other cladding materials. [0003] Solid wood composite door The door of the solid wood composite door is mostly made of pine, fir or imported filler material, and the external density board and solid wood veneer are made by high temperature hot pressing and sealed with solid wood lines. Generally advanced solid wood composite door, the door core is mostly high quality white pine, the surface is solid wood veneer. Due to the low density and light weight of white pine, and it is easier to control the moisture content, the weight of the finished door is lighter, and it is not easy to deform and crack. In addition, the s...
