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...

Abstract

The invention discloses a nano-oxide and soybean protein isolate modified polyadipate / butylene terephthalate composite material, which comprises the following components in parts by weight: polyadipate / butylene terephthalate 100 parts, 1-20 parts of soybean protein isolate, 5-10 parts of nano oxide, 0.2-1 part of lubricant, 0.1-1 part of heat stabilizer. The invention can improve the mechanical properties of poly(butylene adipate / terephthalate) by introducing soybean protein isolate and nano-oxide, and can prevent the plastic from aging too quickly, and prolong the life of the composite material as the base material. The service life of agricultural film products meets the modification requirements of poly(butylene adipate / butylene terephthalate).

Description

technical field [0001] The invention relates to the field of biodegradable polymer composite materials, in particular to a nano-oxide and soybean protein isolate modified polyadipate / butylene terephthalate composite material and a preparation method thereof. Background technique [0002] Polybutylene adipate / terephthalate (PBAT) is a fully biodegradable synthetic polymer material, which has excellent processing properties and is widely used in industry, agriculture, household, packaging and other fields prospect. However, pure polybutylene adipate / terephthalate has disadvantages such as low tensile strength and high cost. Modification methods are needed to improve the mechanical properties of the material and reduce the manufacturing cost of the material. [0003] The ultraviolet rays in the atmosphere are mainly in the 300-400nm band, which will affect the service life of non-disposable plastic products. Therefore, it is necessary to add nanoparticles with strong absorptio...
