Abstract

The invention discloses a novel wood composite board which belongs to the field of composite boards. The novel wood composite board is characterized in that the novel wood composite board consists of a carbon fiber layer, resin layers, wooden board layers, wood-plastic board layers and water proofing layers, wherein a middle layer structure adopts the carbon fiber layer, the resin layers are arranged on the two sides of the carbon fiber layer to improve the hardness and strength, resin is pasted on carbon fibers in the stretching directions of the carbon fibers to form the resin layers, the wood composite board layers are pasted on the outer layers of the resin layers, the wood-plastic board layers are pasted on the outer layers of the wood composite board layers with the resin, and the water proofing layers are pasted on the outer layers of the wood-plastic board layers. A processing method of the wood-plastic composite board comprises the steps of smashing broken straw and wasted chemical fiber scraps, adding slag powder or ash powder and auxiliary agents such as toughening agents and biphasic solvent, mixing in a mixing machine, hot pressing in the mould cavity of a hot pressing machine, conducting switch cooling with cold oil, refrigerating and finalizing. The novel wood composite board has the characteristics of moisture resistance, smooth surfaces, convenience in cleaning, worm-eaten damage prevention, low possibility of cracks and fissures, good bearing capacity, high strength, good durability and environmental protection.

Description

A kind of novel wooden composite plate

Technical fieldThe present invention relates to the composite plate field, specifically relate to a kind of novel wooden composite plate.

Background technologyThe present invention relates to the composite plate field.Along with growth in the living standard, People more and more is paid close attention to natural health, environment friendly and pollution-free house ornamentation environment now; Adopt solid wood materials as decorating and renovating material more, but have moisture-sensitive, easy quilt is damaged by worms; Prolongation along with service time; The phenomenon that crackle and crack can occur influences attractive in appearancely, causes the inconvenience of use.Along with people's improves constantly what living standard required, and the theory of energy-conserving and environment-protective also is rooted in the hearts of the people, and many-sided demands of different of people has been satisfied in the appearance of composite board.

Still there is moisture-sensitive in various degree in the composite plate of nowadays selling on the market, the problem of wiping inconvenience, and also feature of environmental protection aspect can't satisfy people's the health requirements of not having aldehyde benzene fully.

Summary of the inventionDefective in view of existing application technology exists the objective of the invention is to provide a kind of not moisture-sensitive, and smooth surface makes things convenient for wiping, and anti-damaging by worms is not prone to crackle and crack, and bearing capacity is good, and is durable, the novel wooden composite plate of environmental protection.

For realizing above-mentioned purpose, the technical solution that the present invention adopted is by carbon fiber layer, resin bed, and the wood-based planet layer, the Wood plastic boards layer, watertight composition constitutes; Interlayer structure adopts carbon fiber layer, and for adding strong hardness and intensity, both sides are adopted resin bed respectively, and resin can be high temperature resistant; Anti-oxidation, and be insulating materials, resin sticks on the carbon fiber along the carbon fiber draw direction, forms resin bed; The resin bed skin is pasted the wood-based planet layer, and wood-based planet layer skin pasted the Wood plastic boards layer with resin, and Wood plastic boards layer skin pasted watertight composition; Watertight composition can effectively prevent the problem that plate surface makes moist and is prone to damage by worms, and the watertight composition smooth surface, is prone to wiping.

The processing method of Wood plastic boards is with crushed straws, and waste and old chemical fibre rim charge is pulverized, and control order number adds slag powders or grey ground-slag 4%～6%, flexibilizer 0.25% by weight percentage at the 60-80 order; Phase solvent 1%, binder 1%, mobile modifier 2%, coupling agent 2%, activator 0.25%; Paraffin 2%, stearic acid 0.5%, zinc stearate 0.5% is put into mixer and is mixed, and mixes after 5～10 minutes; Mixed raw materials is sent in the hot press die cavity, and the control temperature kept 30 ± 5 minutes at 200 ℃ ± 50 ℃, and controlled pressure is at 20 ± 2Mpa; Switch cooling with cold oil, the refrigeration typing kept 20 ± 2 minutes, made temperature reduce to 50 ℃ ± 5 ℃, promptly made wood-plastic clad plate.

Because the present invention has not moisture-sensitive, smooth surface makes things convenient for wiping, and anti-damaging by worms is not prone to crackle and crack, and bearing capacity is good, and is durable, and the characteristics of environmental protection can be carried out the production of mass, are a kind of new products with promotional value.

Fig. 1 is a structure diagram of the present invention.

Reference numeral shown in Figure 1 is following: 1, carbon fiber layer, 2, resin bed, 3, the wood-based planet layer, 4, the Wood plastic boards layer, 5, watertight composition.

The specific embodiment

In a kind of novel wooden composite plate shown in Figure 1, its specific embodiment is by carbon fiber layer 1, resin bed 2, and wood-based planet layer 3, Wood plastic boards layer 4, watertight composition 5 constitutes; Interlayer structure adopts carbon fiber layer 1; Both sides are adopted resin bed 2 respectively; Resin sticks on the carbon fiber along the carbon fiber draw direction, forms resin bed 2, and resin bed 2 skins are pasted wood-based planet layer 3; Wood-based planet layer 3 skin are pasted Wood plastic boards layer 4 with resin, and Wood plastic boards layer 4 skin are pasted watertight composition 5.

The processing method of Wood plastic boards is with crushed straws, and waste and old chemical fibre rim charge is pulverized, and control order number adds slag powders or grey ground-slag 4%～6%, flexibilizer 0.25% by weight percentage at the 60-80 order; Phase solvent 1%, binder 1%, mobile modifier 2%, coupling agent 2%, activator 0.25%; Paraffin 2%, stearic acid 0.5%, zinc stearate 0.5% is put into mixer and is mixed, and mixes after 5～10 minutes; Mixed raw materials is sent in the hot press die cavity, and the control temperature kept 30 ± 5 minutes at 200 ℃ ± 50 ℃, and controlled pressure is at 20 ± 2Mpa; Switch cooling with cold oil, the refrigeration typing kept 20 ± 2 minutes, made temperature reduce to 50 ℃ ± 5 ℃, promptly made wood-plastic clad plate.

In manufacture process, resin raw material needs sealed storage, keeps fire away, and avoids the sunlight direct irradiation.
