[0004] CN202960472U discloses a pulse pillow for traditional Chinese medicine. The pulse pillow filling material is porous flexible sponge or fiber silk material, which has good elasticity and air permeability. However, the pulse pillow products made of this material often suffer from stress when used. Concentrated at a certain local point, it is easy to cause the patient's muscle tension or arm shaking during the diagnosis and treatment process. In severe cases, there may be a tingling sensation, which will affect the doctor's diagnosis and treatment progress of the disease.

Abstract

The invention relates to a polyurethane composite material for a zero-pressure memory foam pulse pillow and a preparation method of the polyurethane composite material. The polyurethane composite material comprises a component A and a component B, wherein the component A is prepared from raw materials in parts by weight as follows: 45-65 parts of polyether polyol 1, 20-40 parts of polyether polyol 2, 5.0-20 parts of polymer polyol, 0.5-4.0 parts of a chain extender, 2.0-6.0 parts of an opening agent, 1.0-4.0 parts of a catalyst, 0.5-3.0 parts of a foaming agent and 0.2-0.5 parts of a foaming stabilizer; the component B is an isocyanate prepolymer which is prepared from raw materials in parts by weight as follows: polyether polyol, small molecular alcohol and isocyanate. The polyurethane composite material has the characteristics of slow recovery, comfort, mould proof, antibiosis and the like; the zero-pressure memory foam pulse pillow prepared from the composite material has a special shape memory function, produces zero-pressure support on each part of the wrist, promotes the blood circulation and relieves possible fatigue caused by nervousness.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyurethane composite material for a zero-pressure-sensitivity memory foam pulse pillow and a preparation method thereof. Background technique [0002] Polyurethane slow rebound foam, also known as memory foam, is unique in that it can conform to the shape of the load, and the molecular structure "flows and shifts", which maximizes the contact area, minimizes the stress gradient, and relieves the concentrated point of force. There is no local extrusion, approximately static zero pressure. When the temperature of a certain part of the body is transferred to this material, it can remember the shape of external pressure and gradually soften to form the shape of this part of the body, while the part that is not in direct contact still has a certain support force and is extremely comfortable. This memory foam The cotton can be applied in the pulse pillow of t...
