The traditional method is characterized by convenience, easy operation and mass production. However, there are many problems such as easy occurrence of mold or deterioration during the water-absorbing drying process; due to the suppression, the plants can not keep the growth form of the original habitat, the flowers, fruits and leaves are deformed, and the color is also greatly changed. Therefore, some information of the plant, which is closely related to the shape, is lost or misled.
The traditional water-immersed plant three-dimensional specimen can not preserve plants for a long time, especially some rare plants and plants with higher ornamental value, and the preservative solution needs to be replaced frequently, which wastes time and labor. Moreover, the traditional plant three-dimensional specimen can not be disassembled generally, and the plant is difficult to be observed carefully and comprehensively. Meanwhile, the traditional plant three-dimensional specimen is inconvenient to move and carry, needs to be managed regularly, and is relatively time-consuming.
Epoxy resin adhesive (epoxy resin adhesive) generally refers to an adhesive prepared by using epoxy resin as a main body, and is divided into soft adhesive and hard adhesive. However, the existing epoxy resin AB glue is usually not good in high-temperature thermal stability, aging resistance and the like, is easy to reduce in strength especially under high-temperature conditions, and is easy to crack after multiple times of thermal expansion and cold contraction, so that the bonding property of the epoxy resin AB glue is not good under high-temperature environments, and the epoxy resin AB glue is not good in compression resistance and shock resistance and is easy to break. Therefore, a new method for preparing the plant three-dimensional specimen by using the epoxy resin AB glue is needed.
Through the above analysis, the problems and defects of the prior art are as follows:
(1) in the traditional method for manufacturing the plant specimen, the mildew or the quality is easy to occur in the water absorption and drying process; due to the suppression, the plants can not keep the growth form of the original habitat, the flowers, fruits and leaves are deformed, and the color is also greatly changed. Therefore, some information of the plant, which is closely related to the shape, is lost or misled.
(2) The traditional water-immersed plant three-dimensional specimen can not preserve plants for a long time, especially some rare plants and plants with higher ornamental value, and the preservative solution needs to be replaced frequently, which wastes time and labor. Moreover, the traditional plant three-dimensional specimen can not be disassembled generally, and the plant is difficult to be observed carefully and comprehensively. Meanwhile, the traditional plant three-dimensional specimen is inconvenient to move and carry, needs to be managed regularly, and is relatively time-consuming.
(3) The existing epoxy resin AB glue is usually not enough in the aspects of high-temperature thermal stability, aging resistance and the like, particularly, the epoxy resin AB glue is easy to reduce in strength under the high-temperature condition and easy to crack after multiple times of thermal expansion and cold contraction, so that the bonding property of the epoxy resin AB glue is not good under the high-temperature environment, the compression resistance and the shock resistance are not enough, and the epoxy resin AB glue is easy to break.
