Problems solved by technology
Experts and scholars concerned about the development of eucommia gum in the industry believe that for a long time, the planting area of eucommia ulmoides in my country is small, the technology content is low, the promotion efforts cannot keep up, and an industrial chain has not been formed, so farmers are not very enthusiastic about planting

Abstract
The invention relates to a shape memory functional material containing gutta-percha and a method for making the same. The functional material is technically characterized in that the compositions in mass portion are: 10 to 50 portions of gutta-percha, 10 to 60 portions of rubber, 10 to 30 portions of polyethylene, 0.5 to 3 portions of accelerating agent containing sulfur, 1 to 3 portions of antideteriorant, 1 to 5 portions of zinc oxide, 0 to 2 portions of magnesia, 1 to 5 portions of sulfur, 1 to 3 percent of dicumyl peroxide, 10 to 70 portions of siliceous reinforcing agent and 1 to 10 portions of stearine. The invention provides the shape memory functional material containing gutta-percha and the method for making the same and can be applied to produce the products such as an orthopedic external fixation material, a prosthetic limb sleeve, a sports protection tool and a health beauty appliance. A medical gutta-percha plate replaces plaster to serve as the orthopedic external fixation material because the gutta-percha plate is sanitary, light and convenient and radiotransparent X, has convenient and simple operation, high quality and low price, and is more popular compared with other imported macromolecule materials for replacing plaster; the shape memory functional material can be made into a film stuck with the metal perfectly because the material has good radar wave-transparent performance, thereby synthesizing a radar wave-transparent material for sealing a pore radar waveguide antenna and contributing to the development of the war industry.
Description
technical field [0001] The invention relates to a shape memory functional material containing Eucommia gum and a preparation method thereof. Using eucommia gum as the basic raw material, the material with shape memory function was prepared by blending modification. Background technique [0002] Eucommia is a deciduous tree of Eucommiaceae, also known as silk cotton wood. Up to 10 to 20 meters high. The bark is used as medicine, and the Chinese patent medicine with Eucommia as the main raw material is well-known in Southeast Asian countries, Hong Kong and Macao; the leaves can be made into health tea and exported to Japan, and Eucommia gum can also be extracted. In the 1980s, Chinese scientists extracted natural gum from Eucommia ulmoides, and found that the resulting product was very similar to gutta-percha (trans-1,4-polyisoprene) in performance and the same chemical structure, so it is also called Chinese gum. Gutta gum. Experts and scholars concerned about the develop...
