preparation example Construction

[0016] The present invention also discloses a preparation method of the above-mentioned bio-based degradable material, which includes the following steps: after weighing the raw materials in the above-mentioned bio-based degradable material formula in proportion, putting the three kinds of raw materials into a high-speed mixer and stirring them evenly, and then Pour directly into ring mill or flat mill for granulation to form bio-based degradable material.

[0017] The bio-based degradable materials produced by the above method form pellets, which can be used as intermediate materials in the preparation of degradable materials. The bio-based degradable materials are directly mixed with degradable resins, additives and other raw materials, and then poured into double Granulated in a screw extruder to make degradable material. Among them, the degradable resin can be PBAT, PBS, PLA, PHA, PVA, PHB or PHBV, etc., and the additive can be an antioxidant. Since most of the antioxidant...

Abstract

The invention discloses a formula of a bio-based degradable material. The formula comprises the following raw materials in parts by weight: 30-100 parts of biological filler, 1-10 parts of PCL and 1-10 parts of a degradable liquid toughening agent. The preparation method of the bio-based degradable material comprises the following steps: weighing the raw materials in proportion, putting the raw materials into a high-speed stirrer to be uniformly stirred, and then pouring the raw materials into an annular mill or a flat mill to be granulated so as to form the bio-based degradable material. According to the invention, the interface bonding force between the degradable resin and the filler can be increased, the overall thermoplastic processability of the degradable material can be improved, and the cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of degradable composite materials, in particular to a formulation of a bio-based degradable material, a preparation method and an application thereof. Background technique [0002] At present, the requirements for degradable resins in various countries are increasing, but the cost of degradable resins on the market is too high, or the performance itself cannot meet the requirements of use, and there is no way to widely promote them. [0003] Some common degradable materials have the following disadvantages: some have high toughness and poor fluidity; The cost is too high, the market promotion is difficult, and the application field is narrow. Contents of the invention [0004] The purpose of the present invention is to provide a formula of bio-based degradable materials and its preparation method and application, which can increase the interfacial bonding force between the degradable resin and the filler,...
