Description
Technical Field
The invention relates to the field of bedding articles, in particular to a 6D mattress and a preparation process thereof.
Background
In the traditional concept, in order to enhance the supporting effect of the mattress on the human body, antagonistic support is mostly realized by increasing the stiffness and the high elasticity of the mattress, for example, a spring mattress and a palm mattress are in multipoint pressed contact with the human body all the time when in use, the larger pressed area has more obvious rebounding acting force on the human body, so that the mattress can not adapt to the physiological bending of the human body, and the human body can not obtain good body relaxing and fatigue recovery effects.
In contrast, the prior art proposes a sponge mattress made of sponge material to form a mattress body, the sponge material adopted is commonly called memory sponge and slow-rebound sponge in the industry, and is a porous rubber material with a cellular structure of which all or most are open pores, the material has excellent compressibility, can be compressed under low stress, and is easy to recover and has small rebound force. When in use, the sponge mattress can present a collapse surface which is adaptive to the physiological bending of a human body, so that the contact area of the sponge mattress and the human body is increased, the pressure of the weight of the human body is evenly dispersed, the human body obtains a natural state which is close to the physiological bending of the human body, and better body relaxation and fatigue recovery effects are obtained.
The applicant has found, through extensive research, that the above-mentioned advantages of a sponge mattress are mainly due to the particular cellular structure of the sponge mattress. Under a microscope, the cellular structure of the sponge mattress consists of adjacent tiny chamber units, air is contained in the chamber units, and micropores are formed in the side walls of the chamber units and are communicated with the outside and other chamber units. When pressed by an external force, the chamber unit is compressed and discharges air outward through the minute holes. When the external force is relieved, the side wall of the chamber unit rebounds, and air is sucked into the chamber unit through the micropores. The prior art just utilizes micropores to restrict the speed of air sucked into the chamber unit, so that the resilience force of the chamber unit is inhibited, the shape of the chamber unit cannot be quickly recovered, and the recovery time of the sponge mattress is prolonged.
At the same time, the applicant has also found that the sponge material used in the prior art sponge mattresses is highly susceptible to the blocking of the micropores in the side walls of the chamber cells, resulting in a large number of chamber cells being closed cells that are not accessible to the outside, which results in the actual performance of the latex mattress being far below the design expectations.
Disclosure of Invention
The invention provides a 6D mattress in order to make up for the defects in the prior art, and the technical scheme is as follows.
The 6D mattress is provided with a mattress body made of polyurethane foam, the polyurethane foam is made of foam materials with the whole body distributed all over the tiny chamber units, and the side walls of the chamber units are provided with micropores communicated with the outside and other chamber units; 6 external connecting skeletons are formed around the periphery of the cavity unit, and each tiny cavity unit is crosslinked into a three-dimensional network structure through the external connecting skeletons.
In order to realize the 6D mattress in the technical scheme, the invention also provides a preparation process of the 6D mattress, and the technical scheme is as follows.
The 6D mattress preparation process comprises the following steps:
s1, preparing a polyurethane foam cotton semi-finished product with the whole body distributed throughout the micro chamber units through foaming;
s2, blasting and removing membranes from the polyurethane foam semi-finished product prepared in the step S1, so that all chamber units in the polyurethane foam semi-finished product are respectively melted on the side walls to form micropores communicated with the outside and other chamber units, and meanwhile, adjacent side walls between the chamber units are converged to form an externally-connected skeleton, so that all micro chamber units are crosslinked into a three-dimensional net structure through the externally-connected skeleton, and thus a polyurethane foam finished product is obtained;
s3, cutting and forming the polyurethane foam cotton finished product obtained in the step S2 to obtain a cushion body;
and S4, manufacturing the mattress by adopting the mattress body obtained in the step S3.
Compared with the prior art, the invention has the beneficial effects that: the chamber unit in the polyurethane foam cotton adopted by the cushion body has the aperture ratio higher than 85%, the probability of micropore blocking of the side wall of the chamber unit is obviously reduced, 6 externally-connected bones are formed around the periphery of the chamber unit, and each tiny chamber unit is crosslinked through the externally-connected bones, so that the cushion body is softer, and the support for a human body is more uniform.
The present invention will be further described with reference to specific embodiments.

The foam structure of the polyurethane foam adopted by the cushion body is composed of adjacent tiny chamber units, air is contained in the chamber units, and the side walls of the chamber units are provided with micropores communicated with the outside and other chamber units. When pressed by an external force, the chamber unit is compressed and discharges air outward through the minute holes. When the external force is relieved, the side wall of the chamber unit rebounds, and air is sucked into the chamber unit through the micropores. Therefore, the speed of air sucked into the chamber unit is restricted by the micropores, so that the resilience force of the chamber unit is suppressed, and the shape of the cushion body cannot be quickly recovered, thereby prolonging the recovery time of the cushion body. When the pad body is pressed and deformed by human body, it will not rebound immediately, but will recover slowly after a few seconds, so that if the sponge is pressed by hand to rebound slowly, the obvious outline of the handprint can be seen to keep well, and the pad body can remember the shape of the hand.
Obviously, the 6D mattress in the above embodiment can present a collapsed surface adapted to the physiological curvature of the human body when in use, so that the contact area between the mattress and the human body is increased to evenly disperse the pressure of the weight of the human body, so that the human body can obtain a natural state close to the physiological curvature of the human body, and better body relaxation and fatigue recovery effects are obtained.
In addition, in the above embodiment, since the cushion body uses the polyurethane foam to form 6 external connecting bones around the periphery of the chamber unit, and each micro chamber unit is cross-linked by the external connecting bones, the cushion body is softer and the support to the human body is more uniform.
