Embodiment 1

[0026] Composite material preparation method: first, get 50kg polypropylene carbonate and be mixed with the chloroform solution of mass fraction 5%, 10kg terminal hydroxyl branched polystyrene, be mixed with the chloroform solution of mass fraction 10%; Then two The solution is mixed, and the ultrasonic wave is used to promote its uniform mixing, and the time is 10 to 20 minutes. Then, after volatilizing and recovering most of the solvent at normal temperature and low pressure, put it in a vacuum oven, and dry it at 40-50°C to constant weight; then add the obtained mixture and 15kg of propylene-propylene glycol copolymer to the mixing equipment, at 180-200 Melting and blending at ℃, the co-melt formed was dissolved in chloroform again to obtain a solution with a mass fraction of 10%, and finally, 25kg of polyhydroxybutyrate-co-hydroxycaproate was formulated into a mass fraction of 5 % chloroform solution, and ultrasonically mix with the above solution for 20-30 minutes; repeat...

Abstract

The invention relates to a degradable polymer composite material. The composite material is prepared from the following raw materials in parts by weight: 10-30 parts of polystyrene, 30-50 parts of aliphatic polycarbonate, 15-30 parts of a propylene-propylene glycol copolymer and 15-30 parts of polyhydroxybutyrate-co-hydroxy hexanoate. Preparation of the degradable polymer composite material is achieved by a method of combining solution blending with melt blending; and the composite material fully plays a synergistic effect of various components, and has relatively high degradation capability and thermostability and relatively high mechanical property.

Description

technical field [0001] The invention relates to the field of preparation, processing and application of composite materials, in particular to a degradable polymer composite material and a preparation method thereof. Background technique [0002] With the development of science and technology, polymer materials are more and more widely used in social production and life. Plastic, in particular, has become one of the four major industrial materials due to its light weight, corrosion resistance, easy processing, and good overall performance. However, it has a non-negligible impact on the environment, such as visual pollution caused by waste plastic products, air pollution caused by incineration of toxic gases, soil pollution and water pollution caused by burial, and most of the raw materials used in the production process come from petroleum, natural gas, etc. Renewable resources, it can be seen that under the current situation of increasingly scarce resources, the development...
