Description

technical field [0001] The invention relates to the field of injection molding materials, in particular to an antibacterial injection molding material. Background technique [0002] At present, many injection molding materials can realize one-time injection molding of products, without chemical crosslinking, high product purity, simple process, low energy consumption, and high processing efficiency. Especially for medical materials, which are used in related fields such as the rehabilitation of patients, the antibacterial performance is also a particularly important aspect. However, how to improve the antibacterial performance of disposable injection molding materials is still a big problem. [0003] CN106243711A discloses a preparation method for synthesizing antibacterial plastics, and CN 107586433A discloses a durable antibacterial injection molding material for medical components. It is still an urgent problem to develop more and more types of antibacterial injection mo...
