INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD The present invention relates to the field of bamboo composite profiles in which bamboo profiles are bonded to bamboo profiles or wood profiles. [Prior Art] Bamboo consists of an outer layer of bamboo green layer, an inner layer of bamboo yellow layer and an intermediate fiber layer. The bamboo green layer contains a large amount of wax, and the bamboo yellow layer contains a large amount of organic germanium, so it cannot be bonded to other profiles. Therefore, when bonding with other profiles, the bamboo green layer and the bamboo yellow layer should be cut off and bonded with the fiber layer. This method has good adhesion, high relative strength, but material waste is serious, and the process is at the same time. Many, high processing costs are not easy to industrialize. In Chinese Patent No. 200510038523, a process for bonding a bamboo cyan layer to a wood veneer using an isocyanate rubber is provided. As the invention itself claims, the isocyanate rubber is not only expensive but also contains a large toxicity and a high protective requirement during operation. Although it is used in a small amount, the harm to the operator is obvious. At the same time, the composite sheet cannot meet the development requirements of non-toxic and environmental protection. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a bamboo composite profile and a manufacturing method for retaining a bamboo green layer of bamboo and yellow layer for bonding and having high bonding strength, in view of the above-mentioned shortcomings of the prior art. In order to solve the above technical problems, the present invention adopts the following technical solutions: including at least two layers of profiles and an intermediate glue layer bonded to each other, and a bamboo cyan layer or a bamboo yellow layer is dispersed on the bonding surface of the bamboo profiles. The guide rubber eye, the rubber gel layer and the bamboo fiber material layer, the glue layer penetrates into the 200914228 rubber eye and the bamboo profile to form a three-dimensional embedded glue layer. The number of rubber eyes is 70,000 to 90000 / m2, and the depth of the rubber eye is 60 to 80% of the thickness of the bamboo profile. The shape of the guiding rubber eye is a rectangular parallelepiped shape. When the thickness of the bamboo profile is < 6 mm, the length of the guiding rubber eye is 2 - 2.5 mm, the width is 1 - 1.2 mm; when the thickness of the bamboo profile is 26 mm, the length of the guiding rubber eye The adhesive layer of 2.5_3mm and width of 1.5 - 2 mm ° is a non-woven fabric and a glue composite layer, a paper and glue layer or a glue layer. The glue is white latex, wood glue or resin. The guide rubber eye is also disposed on the outer surface of the bamboo profile, and a plastic layer is composited with the outer surface of the bamboo layer through the rubber guide eye. The method for preparing the composite profile comprises the steps of: 1) selecting a bamboo profile; 2) processing the rubber film on the bonding surface of the bamboo profile and guiding the rubber layer of the bamboo profile fiber layer; 3) applying a glue layer on the bonding surface; The embryo is placed in another bonded profile and then formed. Compared with the prior art, the invention realizes the bonding of the bamboo profile and the bamboo profile on the basis of retaining the bamboo profile bamboo layer and the bamboo yellow layer: the bamboo profile is improved, and the bamboo is improved compared with the bamboo profile which removes the bamboo green bamboo yellow layer. The resource utilization rate is 30-500%, which greatly saves the raw materials, avoids the waste of bamboo, and sets the rubber film of the deep and fiber layer on the bonding surface of the bamboo profile, compared with the bamboo blue layer and bamboo yellow. The layer, the fiber layer and the glue have good bonding performance, the glue layer penetrates into the rubber eye and the fiber layer, and the glue and the bamboo material form a three-dimensional embedded glue layer, thereby greatly improving the bonding strength while retaining the bamboo blue layer. And the bamboo yellow layer retains the best material of the original bamboo strength, so the composite material 200914228 after gluing has its own high strength. The number of rubber eyes is 70,000 - 90000 / m2, and the depth of the rubber eye is 60 to 80% of the thickness of the bamboo profile. After a large number of tests, when the number of rubber eyes is more than 90,000 / m2, the rubber eye The density is too large, the bamboo profile is easy to crack, and its strength is reduced. When the number of the rubber guide is less than 70,000/m2, the density is small, which affects the gluing, so the rubber eye is in the range of 70,000 to 90000/m2. Not only greatly improves the strength of the glue, but the bamboo profile does not crack and does not reduce its strength. The shape of the rubber guide eye is a rectangular parallelepiped shape, and the rectangular shape has a good eye-punching property. It does not cause cracks on the surface of bamboo bamboo green or bamboo yellow, thereby preventing the generation of cracks while ensuring the bonding strength, and reducing the bamboo profile itself. Strength of. In order to further improve the strength of the gluing, the gluing layer is a non-woven fabric and a glue composite layer or a paper and glue composite layer, which improves the overall strength of the composite profile while improving the bonding strength.

When the thickness of the bamboo profile is < 6mm, the length of the rectangular shape is 2 - 2.5 mm and the width is 1 - 1.2 mm; when the thickness of the bamboo profile is 26 mm, the length of the rectangular shape of 200914228 is 2.5 - 3 mm and the width is 1.5 - 2 mm ' The depth of the cuboid is 60-80% of the thickness of the bamboo. The glue layer 2 penetrates into the rubber guide 11 to form a three-dimensional embedded glue layer between the wood board 3 and the bamboo board 1. The glue layer 2 can be a simple glue, but in order to further increase the strength and flexibility of the bond, the glue The mixture layer may also be a non-woven fabric and a glue composite layer, a paper and glue composite layer or a glue layer, and the glue is selected from white latex, wood glue powder or resin.
