Cool bamboo charcoal memory foam throw pillow

Abstract

The invention relates to the technical field of polyurethane foam materials, and aims to provide a cool bamboo charcoal memory foam throw pillow, which is characterized by comprising a throw pillow case and a polyurethane memory foam pillow inner, and a cool gel sheet is arranged on the inner side of the throw pillow case. The cool gel sheet is prepared from the following raw materials in parts byweight: 55-80 parts of combined polyether polyol, 15-32 parts of high-resilience polyether polyol, 10-12 parts of temperature-sensitive polyether, 8-12 parts of hydrophobic polyol polyether, 0.3-0.8part of a chain extender, 0.1-0.5 part of a chain extension crosslinking agent, 0.9-1.2 parts of a weak catalyst, 0.5-1.5 parts of a foaming agent, 0.3-0.8 part of a foam stabilizer, 15-25 parts of natural bamboo charcoal powder, 8-15 parts of a cooling additive, 5-8 parts of an antibacterial mildew-proof agent and 45-60 parts of isocyanate; the product prepared by the invention has the advantagesof good heat dissipation effect in summer, coolness, comfort, mildew resistance and mite resistance.

Description

technical field [0001] The application relates to the technical field of polyurethane foam materials, more specifically, it relates to a cool bamboo charcoal memory foam pillow. Background technique [0002] Memory foam (Memory Foam), also known as slow rebound sponge, is a polyurethane polymer with an open cell structure (Open-cell). Absorptive capacity. The open cell structure (Open-cell) of the memory foam will "flow" and displace and deform when it is pressed by an external force, and due to the intermolecular Van der Waals force, the material will perform a uniform and slow recovery on the contact surface that fits the pressure object. elastic, so that the pressure is evenly distributed to the entire contact surface, and the deformed material will slowly return to its original shape when the pressure is removed. Therefore, memory foam is also widely used in pillow cores, pillow cores, seat cushions, back cushions, etc., which significantly improves the comfort and exp...

AI Technical Summary

Problems solved by technology

[0003] Although the commonly used pillow cores are mostly made of polyurethane memory foam, which has a slow rebound memory effect, it is easy to feel stuffy when using this kind of pillow in hot summer, especially when the user holds the pillow, the pillow is in contact with the human body The heat in the parts is not easy to dissipate, which aggravates the stuffy feeling and reduces the user experience

[0004] In view of the related technologies mentioned above, the inventor believes that the current memory foam pillows have poor heat dissipation effect in actual use and are prone to stuffy feeling, which needs to be further improved.
