Description

Composite pillow and preparation method thereof

Technical Field

The invention relates to the technical field of pillow manufacturing, in particular to a composite pillow and a preparation method thereof.

Background

Sleep is a healthy root, and people have healthy bedding which is sanitary, comfortable and durable, besides the reasons of work, life, body, psychology and the like, which is the key point for obtaining high-quality sleep. A good sleep is very important to the health of a person, since a large part of the life of a person is spent in sleep.

With the continuous progress of material culture and technical process, the types of mattresses used by modern people gradually tend to be diversified, but most of the pillows used by people use fillers such as grains and cotton wool as the fillers of the pillows. Therefore, the traditional pillow has poor air permeability and slow heat dissipation, so that heat generated by the head of a person cannot be dissipated in time when the pillow is used in summer, the body of the person easily feels stuffy and wet and hot, and the good sleep cannot be provided for the person.

Therefore, people invent and use the polyurethane pillow, and the polyurethane pillow can generate rebound force with different supporting force under different deformation states when being pressed and can generate corresponding deformation along with the curve of a human body or the curve of a neck. The gel coating is coated on the surface of the polyurethane sponge pillow, so that the surface of the mattress or the pillow has a cool feeling, and people feel more comfortable in summer. However, some of the gel coatings in the existing pillows are formed by coating gel on the pillows by using a roll coating or spray coating method, but the side surfaces of the pillows are difficult to coat due to the fluidity of the gel, even if the side surfaces can be coated with a thin layer, the side surfaces of the pillows are difficult to coat flatly, so the gel layers are not coated on the side surfaces of the pillows by using the roll coating or spray coating method in the prior art.

Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1, it is a schematic structural view of the composite pillow provided by the present invention. The composite pillow comprises a pillow core 10 and a gel coating layer 11 coated on the outer side of the pillow core 10. In addition, in order to avoid the contamination of the composite pillow, the outer side of the gel coating layer 11 further comprises a protective film, which is well known to those skilled in the art and will not be described herein again.

The pillow core 10 is made of polyurethane sponge, and the polyurethane sponge can be made of various polyether polyols or polymer polyols, isocyanate, stannous octoate, diethanolamine, triethanolamine, an organic silicon foam stabilizer, an amine catalyst and other materials. The polyurethane sponge has the rebound force which can generate different supporting forces under different deformation states when being pressed, and can generate corresponding deformation along with the curve of a human body or the curve of a neck, so that the pillow is more accordant with human engineering, and people can feel more comfortable when sleeping.

The gel coating layer 11 comprises an upper cover 12 along the sleeping pressure direction of the pillow core 10, the upper cover 12 comprises a cover body 14, and a cover edge 15 arranged on the periphery of the cover body 14. The lid rim 15 is integrally formed with the lid body 14. Since the cover edge 15 includes four sides for a general pillow, any two adjacent sides of the four sides are also integrally formed therebetween. The material for preparing the gel coating layer 11 comprises one or more polyether polyols and modified isocyanate which are synthesized when the gel coating layer is not foamed. Of course, it is conceivable that the material of the gel coat layer 11 also comprises other materials, for example, a blue colorant is also included in the material of the gel coat layer. By adjusting the ratio of the polyether polyol or polyols and the modified isocyanate, the hardness of the gel coat layer 11 can be adjusted. Therefore, the gel coating layer 11 is composed of a hard layer and a soft layer, and the soft layer is connected with the pillow core. The ratio of the one or more polyether polyols to the modified isocyanate in the hard layer is 100: 25 to 30. The ratio of the one or more polyether polyols to the modified isocyanate in the soft layer is 100: 20 to 25. Because the gel coating layer is provided with the hard layer, the composite pillow does not need a protective film and can be directly contacted with the skin of a person. According to different pillow forms, there are a round pillow and a right-angle pillow, so when the pillow is a round pillow, the cover edge 11 further includes four transition arcs disposed between any two sides of the four sides, and the transition arcs are integrally formed with the adjacent sides.

The invention also provides a preparation method of the composite pillow, which comprises the following steps:

STEP1 providing a gel sheet comprising a hard layer and a soft layer;

STEP2 providing a mold for molding the pillow core and including an upper mold and a lower mold, flatly placing the gel sheet into the lower mold, facing the soft layer to the material injection surface of the pillow polyurethane material, and pouring the pillow polyurethane material on the soft layer surface of the gel;

STEP3, closing the upper die and the lower die, foaming and curing for 5-10 minutes to form the composite pillow;

in order to make the pillow core more breathable, the gel sheet can be provided with a plurality of through holes arranged at intervals.

The manufacturing method of the composite pillow also comprises the preparation method of the gel sheet, namely, a mould with proper specification is selected, a layer of centrifugal paper is laid under the mould, the soft layer gel material is poured on the centrifugal paper, after the reaction and the curing are carried out for 1-5 minutes, the hard layer gel material is poured on the soft layer gel, and the curing is carried out for 1-5 minutes.

Compared with the prior art, the composite pillow provided by the invention has the advantages that the side surface of the pillow can be provided with the gel coating layer 11 through the preparation method of the composite pillow, the upper cover 12 of the gel coating layer 11 can be made of the cover body 14 and the cover edge 15, the upper cover 12 can be integrally formed, and the cover edge 15 can be integrally formed. For a common pillow, the cover edge 15 is rectangular, and the four edges can be integrally formed, so that no matter any two of the four edges are in round angle transition or right angle transition, the cover edge can be integrally formed without any trace, and therefore, the gel layer can be coated on one side or two sides of the whole pillow, the whole gel layer is flat and smooth, the appearance of people is attractive, and the use experience of users is improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
