Bio-based hydrophilic zero-pressure material and preparation method thereof

Abstract

The invention discloses a bio-based hydrophilic zero-pressure material and a preparation method thereof, and the bio-based hydrophilic zero-pressure material comprises the following raw materials by weight: 55-75 parts of bio-based macromolecular first polyol, 25-45 parts of bio-based macromolecular second polyol, 0-10 parts of bio-based macromolecular third polyol, 1.5-2.5 parts of a foam stabilizer, and 0.5-1 part of a composite amine catalyst. The surface hardness of the hydrophilic zero-pressure material prepared by the method is lower than 1asker F and even reaches 0asker F, and the hydrophilic zero-pressure material is used for mattresses, pillow surface layers, air conditioning quilt linings, corseses and the like, has excellent comfort, can sense the temperature of a human body, forms a shape completely conforming to the human body, provides comfortable embracing and supporting for the human body, and reaches a zero-pressure state, The compression of blood vessels and nerves is relieved, so that the times of turning over and stiff neck are reduced, and a good sleep quality effect is achieved. A hydrophilic pore-foaming agent is arranged, air flows among foam molecules through an open pore type molecular structure, hot air emitted by a human body and air flow in the air are emitted into the air from the periphery of the air flow product, and the effects of ventilation, heat dissipation and stuffiness prevention are achieved.

Description

technical field [0001] The invention relates to the technical field of soft polyurethane foam, in particular to a bio-based hydrophilic zero-pressure material and a preparation method thereof. Background technique [0002] Soft polyurethane foam (commonly known as sponge) products are widely used in daily life. From car seats to mattress pillows to bras, soft polyurethane foam is essential. In a large number of applications, flexible polyurethane foam products are used in parts that come into contact with the human body. In this case, the softness and comfort of cotton products are very important, and this is one of the reasons why materials such as cotton, silk floss, and latex are widely used. The traditional sponge, whether it is ordinary cotton, high resilience or memory foam, cannot achieve the softness close to the skin's touch due to its material structure. There are also some related research in the industry, but the effect is not ideal. Disclosed is a preparatio...

Problems solved by technology

Combining the above elements, the bio-based hydrophilic zero-pressure material is very delicate and soft, which solves the problem that the softness of polyurethane foam made by traditional methods is limited and cannot achieve skin-friendly softness.
