Abstract

The invention provides a polyurethane memory foam material for a mattress as well as a preparation method of the material. The polyurethane memory foam material comprises the following raw material components in parts by mass: 40 to 60 parts of diisocyanate, 90 to 110 parts of poly-polyol, 10 to 15 parts of a chain extender, 5 to 10 parts of carbon fiber, 1.5 to 3 parts of a foaming agent, 1 to 2parts of a foam stabilizer, 0.5 to 1 part of a pore opening agent and 0.3 to 1 part of a catalyst, wherein the poly-polyol comprises low-molecular-weight poly-polyol with the number-average molecularweight of 800 to 1500, medium-molecular-weight poly-polyol with the number-average molecular weight of 3000 to 5000 and high-molecular-weight poly-polyol with the number-average molecular weight of 8000 to 12000. The polyurethane memory foam material is prepared by a method for performing polymerization foaming at one step and finally curing. The polyurethane memory foam material provided by the invention has high strength, has glass transition temperature close to the human body temperature, has high shape recovery ratio and is particularly suitable for a mattress material.

Description

technical field [0001] The invention belongs to the technical field of shape-memory polyurethane materials, and in particular relates to a polyurethane memory foam material for mattresses and a preparation method thereof. Background technique [0002] Shape memory polymer generally refers to a polymer material that can restore its original shape after being stimulated by external conditions (such as heat, electricity, light, chemical induction, etc.) after a product with an initial shape changes its original shape and is fixed under certain conditions . According to its recovery principle, it can be divided into thermotropic shape memory polymers, electrotropic shape memory polymers, phototropic shape memory polymers, chemical induction shape memory polymers, etc. As a class of extremely important shape memory materials, shape memory polymers have been widely used in aerospace, biomedicine, power electronics, packaging, intelligent control systems and other fields. Among t...
