Problems solved by technology

However, the existing MDI foam material is prone to closed cells, poor air permeability, easy to harden at low temperature, and the side is easy to crack when the mold is opened, which affects the appearance and yield
[0004] At the same time, the existing health pillows are generally difficult to clean, and are prone to bacteria and mites after long-term use. Therefore, new requirements are put forward for the antibacterial properties of pillows.

Embodiment 1

[0031] Embodiment 1: the sleeping pillow comprising modified MDI foam provided by this embodiment, refer to Figure 1-4 , including a pillowcase (not shown in the figure) and an inner pillow body formed by modified MDI foam. The upper section of the inner pillow body 1 is provided with a head groove 2, and the lower section is provided with a triangular-like soft body 4. On the head A neck groove 3 is preset between the groove and the triangular-like soft body, and cooperate with each other to support the head, neck, and chest in a straight line. There is an angle of 35 degrees between the upper surface of the upper surface and the lower surface of the inner pillow body; the quasi-triangular soft body is similar to the duck tongue structure. Adopting the principle of ergonomic design, the cervical traction is increased through the grooves of the head and the neck, and the triangular-like software is used for support to achieve zero pressure on the cervical spine, soft support,...

Embodiment 2

[0037] Embodiment 2: The sleep pillow comprising modified MDI foam provided by this embodiment is substantially the same as that of Embodiment 1, except that:

[0038] A modified MDI foam is made of the following components in parts by weight: 70 parts of diphenylmethane diisocyanate MDI, 35 parts of hydroxyl-terminated polydimethylsiloxane, 3 parts of carboxymethyl chitosan quaternary ammonium salt 4 parts, Phellodendron cortex extract, 10 parts of nano-silver-loaded titanium dioxide, 0.5 parts of graphite fluoride, 4 parts of surfactant, 0.9 parts of catalyst, 1 part of chain extender, and 5 parts of foaming agent. Among them, the blowing agent is cyclopentane; the catalyst is triethylenediamine; the surfactant is Momentive L-580 and Evonik B8715 at a mass ratio of 1:3; the chain extender is glycerin.

[0039] In the specific preparation process: control the temperature of material A and material B at 28°C, and the speed of high-speed stirring at 2000 rpm; control the temperat...

Embodiment 3

[0041] Embodiment 3: The sleeping pillow comprising modified MDI foam provided by this embodiment is substantially the same as that of Embodiment 1, except that:

[0042] A modified MDI foam is made of the following components in parts by weight: 63 parts of diphenylmethane diisocyanate MDI, 24 parts of hydroxyl-terminated polydimethylsiloxane, 3 parts of carboxymethyl chitosan quaternary ammonium salt 6 parts, Phellodendron Phellodendri extract, 9 parts of nano silver-loaded titanium dioxide, 1 part of graphite fluoride, 3 parts of surfactant, 0.5 part of catalyst, 6 parts of chain extender, and 3 parts of foaming agent. Among them, the foaming agent is 15wt% sodium bicarbonate solution; the catalyst is dimethylethanolamine and organotin compounded at a mass ratio of 3:1; the surfactant is Momentive L-8002 and Evonik B8158 at a mass ratio of 2 : 3 compounds; the chain extender is castor oil.

[0043] In the specific preparation process: control the temperature of material A ...

Abstract

The invention discloses a sleep pillow containing modified MDI (diphenylmethane diisocyanate) foam, which comprises a pillowcase and an inner pillow body that is obtained by molding the modified MDI foam, wherein the upper segment of the inner pillow body is provided with a head groove, the lower segment of the inner pillow body is provided with a triangle-like soft body, a neck groove is preset between the head grove and the triangle-like soft body, and mutual cooperation is performed to keep the head, neck and bosom at the same straight line; the modified MDI foam is prepared from the following components in parts by weight: 60-70 parts of MDI, 20-35 parts of hydroxy-terminated poly-dimethylsiloxane, 2-3 parts of quaternized carboxymethyl chitosan, 4-9 parts of golden cypress extracting solution, 8-10 parts of nanometer silver-loaded titanium dioxide, 0.5-1.5 parts of fluorinated graphite, 2-4 parts of surface active agent, 0.3-0.9 part of a catalyst, 1-6 parts of a chain extender and 1-5 parts of a foaming agent. Compared with the prior art, the sleep pillow containing modified MDI foam has the advantages of having no pressure caused to the cervical vertebra, bearing softly, being appropriate in rebound resilience and good in limpness at a low temperature, self-cleaning, and being anti-microbial, anti-acarien, non-toxic, environmentally friendly and the like.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a sleeping pillow containing modified MDI foam. Background technique [0002] Traditional pillows are usually filled with solids, which are bulky, inconvenient for storage and transportation, and many of them rest the head instead of the neck, causing compression of the cervical spine, changing the normal physiological curve of the cervical spine, causing muscle fatigue and ligament stretching or damage , causing "stiff neck", often in this situation is one of the common causes of cervical spondylosis. Along with the improvement of people's quality of life and the emphasis on health, it is very urgent to develop a healthy and comfortable sleep pillow to improve the above problems. [0003] The curing rate of diphenylmethane diisocyanate MDI (expressed in this article as MDI) is faster than that of toluene diisocyanate commonly known as TDI (hereinafter expressed in TDI...
