Abstract

The invention relates to biomass-based polyurethane foam containing vegetable oil residue, which is composed of a biomass liquification product, a catalyst, a foam stabilizer, vegetable oil residue and isocyanate. The invention also relates to a preparation method of the biomass-based polyurethane foam containing vegetable oil residue. The polyurethane foam provided by the invention has better degradation property, thus waste biomass is completely utilized and the pressure of petrochemical resources is reduced; the preparation cost is lower, and the raw materials are inexpensive, easily available and renewable; and the pore structure of the polyurethane foam material is improved and the compressive strength of the foam is improved.

Description

technical field [0001] The invention belongs to the field of chemical polymers, and in particular relates to a biomass-based polyurethane foam containing vegetable oil residue and a preparation method thereof. Background technique [0002] As a class of polymer materials, polyurethane foam has been widely used in various fields such as transportation, furniture, beds, construction and heat insulation because of its low relative density, high specific strength, excellent thermal properties and good processing performance. In recent years, polyurethane foam materials have opened up new uses in the fields of agriculture, medicine and health, three wastes treatment, energy saving, space flight, national defense and military affairs, and become one of the most widely used varieties of materials. According to the different raw materials used and the change of the formula, it can be made into soft, semi-rigid and rigid polyurethane foam materials. [0003] At present, the raw mate...
