Abstract
The invention belongs to the field of polyurethane foaming, and particularly relates to a polylactic acid polyurethane material and a preparation method thereof. The polylactic acid polyurethane material is prepared from a component A and a component B. The component A comprises the following raw materials in parts by weight: 50-200 parts of polyether polyol 1, 50-200 parts of polyether polyol 2 and 10-100 parts of TDI, wherein the functionality of the polyether polyol 1 is 2, and the molecular weight of the polyether polyol 1 is 1000-12000; and the functionality of the polyether polyol 2 is 3, and the molecular weight of the polyether polyol 2 is 1000-12000. The component B comprises the following raw materials in parts by weight: 20-200 parts of polylactic acid, 20-200 parts of a chain extender and 10-50 parts of a silane coupling agent. The prepared polylactic acid polyurethane material is good in biocompatibility, friendly to environment, resistant to bacteria and biodegradable, and the preparation method is simple in process.
