Abstract

The utility model discloses a composite wooden board. The composite wooden board comprises a solid board at the lower layer and a wedge joint board at the upper layer; and the composite wooden board is characterized in that a glass fiber mesh layer is molded between the wedge joint board and the solid board, a waterproof protection layer covers the wedge joint board, and the waterproof protection layer is embedded with reinforcing ribs. The composite wooden board disclosed by the utility model not only is firm in structure and strong in bearing ability, but also has a better waterproof performance.

Description

Composite wood board
Technical field
The utility model relates to architectural decoration material field, relates in particular to the composite wood board that a kind of bearing capacity is strong and water resistance is good.
Background technology
Along with the pursuit of people to quality of the life, increasing people likes decorating household with solid wood board.Solid wood board sheet material is sturdy and durable, the lines nature, mostly has the distinctive fragrance of natural timber, has hygroscopicity and gas permeability preferably, is of value to health, does not cause environmental pollution, is the high-quality sheet material of making top-grade furniture, decorating house.Some special substances are still made the ideal material of gun stock, precision instrument as the solid wood board of beech.
But solid wood board also has its weak point, and that is exactly that cost and construction process requirement are higher.
Because solid wood board class sheet material cost is high, and construction process requirement is high, uses also few on the contrary in finishing.In addition, timber resources is limited, makes to utilize in a large number solid wood board to become possibility as manufacturing furniture, decorating house.Due to these reasons, the solid wood board of pure solid wood is difficult to promote.Along with improving constantly of the level of production, some composite wood boards that are applied to the building decoration field arise at the historic moment.Publication number is CN 201220440, discloses a kind of composite wood plate for the Chinese patent literature of 2009.04.15, and it is characterized in that in open day: be three-layer composite structure, upper and lower two-layer be finger-jointed plate, be provided with the solid wood cortex of traverse between upper and lower finger-jointed plate.This patent documentation is due to the two-layer finger-jointed plate that is in up and down, and finger-jointed plate is to be formed by the polylith wood board splicing, no longer glues up and down and presses clamping plate, and glue consumption greatly reduces, and has saved to a certain extent production cost.But because being is formed by the polylith wood board splicing, the glue that finger-jointed plate is used is generally milky white adhesive, i.e. the aqueous solution of polyvinyl acetate.Due to the two-layer all use in up and down is finger-jointed plate, in case meet for a long time water, will reduce the viscosity of milky white adhesive, thereby make finger-jointed plate produce the crack, and then soak the solid wood cortex of the layer that mediates, seriously reduced the normal service life of composite wood board, in addition, its bearing capacity also a little less than, be not suitable for putting in the above some weights.
The utility model content
The utility model is intended to provide for the relatively poor defective of above-mentioned prior art water resistance the composite wood board that a kind of bearing capacity is strong and water resistance is good.The utility model is not only firm in structure, and bearing capacity is strong, and has good water resistance.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
Composite wood board comprises the solid wood board of lower floor and the finger-jointed plate on upper strata, it is characterized in that: be injected with the glass fibre stratum reticulare between described finger-jointed plate and solid wood board, covering on described finger-jointed plate has fish tail and waterproof layer, is embedded with reinforcement on described fish tail and waterproof layer.
The thickness of described glass fibre stratum reticulare is 5-10mm.
Described fish tail and waterproof layer is polyvinyl chloride layer or layer of polyurethane.
Described reinforcement is circular.
Glass fiber mesh chemical stability described in the utility model is good, alkali resistant, acidproof, water-fast, water-fast mud etch, and anti-other chemical attacks; Strong with resin-bonded property, be soluble in styrene; Have high strength, high-modulus, lightweight characteristics.
Polyvinyl chloride true qualities described in the utility model are that little yellow is translucent, and are glossy; Transparency is better than polyethylene, polypropylene, is worse than polystyrene, and is different with auxiliary dosage, is divided into soft, PVC-U, and soft goods is gentle and tough, and feel is sticking, and the hardness of boardy product is higher than low density polyethylene (LDPE), and lower than polypropylene, albinism can appear in the place in flexion.
Polyurethane described in the utility model is the polymer of being made by raw materials such as the chain extenders such as polyisocyanates and PPG or PEPA or polyamine or water or crosslinking agents, has stronger resistance to water.
The beneficial effects of the utility model are mainly manifested in the following aspects:
One, the utility model, with publication number be CN 201220440, compared for the Chinese patent literature of 2009.04.15 in open day, covering on finger-jointed plate has fish tail and waterproof layer, fish tail and waterproof layer adopts polyvinyl chloride or polyurethane, these two kinds of materials all have stronger resistance to water and corrosion resistance, can effectively protect finger-jointed plate not to be damaged; Be embedded with reinforcement on fish tail and waterproof layer, improved the composite wood board overall construction intensity, strengthen bearing capacity.
Two, the utility model, with publication number be CN 201220440, compared for the Chinese patent literature of 2009.04.15 in open day, the thickness of glass fibre stratum reticulare is arranged to 5-10mm, make whole composite wood board rational in infrastructure, when strengthening water resistance, also alleviated the quality of composite wood board.
Three, the utility model, with publication number be CN 201220440, compared for the Chinese patent literature of 2009.04.15 in open day, the reinforcement setting is circular, further improved the structural strength of whole composite wood board, the service life of prolongation composite wood board.
