Embodiment 1
[0024] A modified polyadipate / butylene terephthalate composite material containing nano-oxide and soybean protein isolate, calculated in parts by mass, its composition and content are as follows:
[0025]
[0026] Above-mentioned formula reacts according to the following steps:
[0027] (1) Put a certain amount of soybean protein isolate into a 60°C oven and dry to constant weight, then take a certain amount of pre-dried soybean protein isolate, add epichlorohydrin (45% by mass fraction of soybean protein isolate) ) in a beaker, stirred evenly with a glass rod, and then placed in a mold of a flat vulcanizing machine for curing and molding. The temperature of the flat vulcanizing machine was set at 80°C, the pressure was 30 MPa, and the temperature was kept at a constant temperature for 5 minutes.
[0028] (2) After the pressure holding is completed, open the mold and take out the sample. After it is cooled to room temperature, use a high-speed pulverizer to pulverize the so...
