Abstract
The utility model discloses bamboo-made composite profile, which comprises at least two layers of profile, and a binding material layer in the middle. The utility model is characterized in that scattered gel guiding eyes are arranged on the bamboo green layer or the bamboo yellow layer of the adhesive surface of the bamboo profile, the gel guiding eyes are penetrated through the fiber layer of the bamboo profile, and the binding material layer is infiltrated into the three dimensional embedded type binding material layer formed by the gel guiding eyes and the bamboo profile; the quantity of the gel guiding eyes is 70000 to 90000 pcs/m<2>, and the depth of the gel guiding eyes is 60 to 80 percent of the thickness of the bamboo profile; the axial distance of two adjacent gel guiding eyes is 4 to 6 mm, and the radial distance of two adjacent gel guiding eyes is 2 to 4 mm. Compared with the prior art, on the basis of retaining the bamboo green layer and the bamboo yellow layer of the bamboo profile, the adhesive bonding of the bamboo profile is realized in the utility model, and compared with the bamboo profile which removes the bamboo green layer and the bamboo yellow layer, the utilization ratio of the bamboo resource is improved by 30 to 50 percent, the gel guiding eyes penetrated through the fiber layer are arranged on the adhesive surface of the bamboo profile, the glue water and the bamboo profile form a three dimensional embedded type binding material layer, and therefore the bonding strength is greatly improved.
Description
Technical field
The utility model relates to the bamboo composite section bar field of bondings such as a kind of bamboo profile and bamboo profile or wooden profile material.
Background technology
Bamboo is made up of the tabasheer layer and the middle fibrage of outer field bamboo green layer, internal layer, bamboo green layer contains a large amount of cured matter, and the tabasheer layer contains a large amount of organosilicons, thereby can't bond with other section bars, so the time with other section bar bondings, all bamboo green layer tabasheer layer will be cutd open, fiberfill layer bonds, and this method caking property is good, relative intensity is higher, but waste of material is serious, and operation is many simultaneously, and the processing cost height is not easy to industrialization.A kind of bonding process that utilizes isocyanate glue to carry out bamboo green layer and Wooden veneer is provided in Chinese patent 200510038523, said as invention itself, isocyanate glue is the price height not only, and it is bigger to contain toxicity, requirement of shelter is also high during operation, and to the greatest extent let it be, and consumption is few, but is conspicuous to the harm that the operator brings, simultaneously, this composite board can not be complied with the demand for development of asepsis environment-protecting.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of bamboo composite section bar that bamboo green layer tabasheer layer bonds and bonding strength is high that keeps is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: at least 2 stratotype materials and the middle glue layer that comprise mutual bonding, lead the glue eye what the adhesive surface bamboo green layer of described bamboo profile or tabasheer layer were provided with dispersion, this leads the material fibrage of the dark and bamboo type of glue eye, and described glue layer is infiltrated and describedly led the glue eye and bamboo profile forms three-dimensional embedded glue layer.
The quantity of leading the glue eye is 70000-90000/m
2, the degree of depth of leading the glue eye is the 60-80% of bamboo profile thickness.
The described cuboid that is shaped as of leading the glue eye, when the thickness of bamboo profile＜6mm, the length of leading the glue eye is 2-2.5mm, wide 1-1.2mm; As bamboo profile thickness 〉=6mm, the length of leading the glue eye is 2.5-3mm, and width is 1.5-2mm.
Described glue layer is nonwoven and glue composite bed, paper and glue composite bed or glue layer.
Described glue is white glue with vinyl, ureaformal dehyde resin glue or resin.
Outer surface at bamboo profile also is provided with the described glue eye of leading, and a plastic layer is by leading the glue eye and bamboo wood layer outer surface is compound.
Compared with prior art, the utility model is on the basis that keeps bamboo profile bamboo green layer and tabasheer layer, realized the gummed of bamboo profile and bamboo profile, compare with the bamboo profile of removing surf green tabasheer layer, improved the 30-50% of bamboo resource utilization rate, raw material have been saved greatly, avoided waste to bamboo wood, and dark and the fibrolaminar glue eye of leading are set at the adhesive surface of bamboo profile, compare bamboo green layer and tabasheer layer, fibrage and glue have good glue performance, and glue layer is infiltrated and led glue eye and fibrage bonding, and glue and bamboo profile form three-dimensional embedded glue layer, thereby improved bonding strength greatly, keep bamboo green layer and tabasheer layer simultaneously, kept the best material of former bamboo intensity, thereby self intensity of the composite material behind the gummed is also high.
The quantity of leading the glue eye is 70000-90000/m
2, the degree of depth of leading the glue eye is the 60-80% of bamboo profile thickness, through a large amount of test, when the quantity of leading the glue eye greater than 90000/m
2The time, the density of leading the glue eye is excessive, bamboo profile easily splits, its intensity decreases on the contrary, when the quantity of leading the glue eye less than 70000/m
2, density is less again, and therefore the influence gummed leads the glue eye at 70000-90000/m
2In the scope, the both fine intensity that has improved gummed, bamboo profile does not ftracture simultaneously, does not reduce self intensity.
Lead the cuboid that is shaped as of glue eye, cuboid has good stamp eye, can not make bamboo wood surf green or tabasheer surface form crackle, thereby when guaranteeing bonding strength, also prevent the generation of crackle, reduces the intensity of bamboo profile self.
In order further to improve the intensity of gummed, cementing layer is nonwoven and glue composite bed or paper and glue composite bed, when improving bonding strength, has also improved the overall performance of composite material.
