Description

POE (polyolefin elastomer) compatibilizing material, preparation method and high-performance PGA (PGA) material Technical Field The invention relates to the technical field of polymers, in particular to a POE compatibilizing material, a preparation method and a high-performance PGA material. Background The application field of 3D printing technology is very wide, almost covering various fields of manufacturing industry. In terms of prototype design, 3D printing techniques can quickly prototype products, helping designers and engineers to verify the feasibility of the design. In terms of production applications, 3D printing technology has gradually shifted from prototyping to production applications, especially in the high-demand fields of medical, aerospace, automotive, etc., and 3D printing technology has shown great potential. For example, in the medical field, 3D printing techniques may produce personalized medical devices and implants, and in the aerospace field, 3D printing techniques may print complex parts and structures. The 3D printing technology of degradable materials is a leading-edge field combining environmental protection and advanced manufacturing technology. The technology utilizes biodegradable materials to construct three-dimensional entities in a layer-by-layer stacking mode, and has wide application prospect and important environmental protection significance. In recent years, with the increasing global awareness of environmental protection, the demand for degradable materials has been shown to increase in blowout. PGA (polyglycolide or polyglycolic acid) has been an important biodegradable material, and has been an important role in replacing conventional plastics, reducing environmental pollution, and the like, and its market size has been continuously expanding in recent years. It is predicted that by 2029, the global PGA resin market size will reach $ 5.2 billion and is expected to continue to grow at a composite annual growth rate of 26.7% in the next few years. The industrial production technology of PGA has been relatively mature and mainly includes a glycolic acid (ester) polycondensation method, a glycolide ring-opening polymerization method and the like. With the continuous progress of technology, the production cost of PGA is gradually reduced, and the productivity is continuously enlarged, so that powerful support is provided for the application of PGA in wider fields. The chinese PGA industry is coming with the opportunity for rapid development. A plurality of large PGA projects are successively landed, such as 5 ten thousand tons/year and 20 ten thousand tons/year polyglycolic acid projects of the national energy group elm chemical industry limited company, and the like. Implementation of these projects not only promotes rapid promotion of PGA productivity, but also promotes improvement of industry chains and promotion of technical level. PGA also has excellent workability, and can be synthesized and processed by various methods. PGA is chemically stable, but can be rapidly degraded under specific conditions (e.g., water and microbial action), and the final degradation products are carbon dioxide and water, which are environmentally friendly. The degradation rate is the fastest in degradable plastics and no special degradation conditions are required. PGA is widely used in medical fields such as surgical suture lines, drug controlled release carriers, fracture fixation materials, tissue engineering scaffolds, etc., because of its good biocompatibility and degradability. PGA can be degraded into water and carbon dioxide in a human body, so that rejection reaction is not caused, and PGA can be used as a completely biodegradable plastic to replace the traditional plastic in various fields such as agricultural films, fresh-keeping packages, bottle materials and the like, although PGA materials have new material green labels, the structural problem of PGA leads to material performance defects, and the application of the PGA has great limitation. How to solve the problems of low hardness, poor toughness, large brittleness, high crystallization speed, poor fluidity and the like of materials is a difficult problem which needs to be solved in the modified blending processing. Disclosure of Invention In order to solve the problems, the invention provides a POE (polyolefin elastomer) compatibilizing material, a preparation method thereof, a high-performance PGA material and a preparation method thereof, wherein the POE compatibilizing material with better hardness, rebound resilience and heat resistance is obtained by adding a cross-linking agent, a cross-linking auxiliary agent and carboxyl butylbenzene rubber powder, and the POE compatibilizing material is used as a toughening base material of the PGA material to obtain the green and environment-friendly high-performance PGA material with better rigidity, strength, shock resistance, toughness, fluidity and glass transition temperat
