Abstract

The invention discloses a bio-based polyurethane composite material containing CBD and a preparation method of the bio-based polyurethane composite material. Raw materials of the composite material comprise a component A and a component B, wherein the ratio of the component A to the component B in parts by weight is 100: (20-50). The component A is prepared from the following components, by weight: 40 to 60 parts of vegetable oil-based polyol, 35 to 50 parts of polyether polyol I, 0 to 10 parts of polyether polyol II, 0.5 to 5 parts of CBD, 0 to 5 parts of natural pigment, 0 to 3 parts of silicone oil, 0 to 5 parts of a cross-linking agent, 0.2 to 1 part of a catalyst and 0.8 to 4 parts of water; and the component B comprises the following components, by weight: 20-50 parts of modified MDI. The composite material has good stability and excellent degradation performance; by adding the CBD, anxiety of people can be relieved and sleep quality of people can be improved in the sleep processof people, and by adding the natural pigment, a bactericidal effect can be achieved, and the polyurethane material is effectively prevented from mildewing.

Description

technical field [0001] The invention belongs to the field of polymer chemistry, and in particular relates to a CBD-containing bio-based polyurethane composite material and a preparation method thereof. Background technique [0002] Polyurethane is a common polymer material that is widely used in daily life. However, most of the polyols used in the production of polyurethane come from petrochemical products, and as non-renewable petroleum resources are limited and cannot be degraded naturally. One of the major problems in polyurethane products is that they can only be disposed of by burning at the end of their useful life, which will cause air pollution. [0003] Because the natural vegetable oil base is sustainable and degradable, it reduces dependence on petrochemical products. Therefore, more and more natural vegetable oil-based materials are applied to polyurethane materials. However, because vegetable oil-based polyurethane composite materials are high-protein material...
