Description
Technical Field
The invention relates to the technical field of mattresses, in particular to a functional mattress and a preparation method thereof.
Background
The development history of the mattress is long, the variety is various, the mattress is closely related to the life of people, the shape and the manufacturing materials are various, one third of the time of people is spent on the bed, the mattress is a main appliance for people to sleep and rest, and the mattress is provided with a latex mattress, a soft mattress, a spring mattress and the like, and has the effects of releasing the spinal pressure, relieving the muscle fatigue and the like. With the improvement of living standard and the transformation of consumption concept, the requirement on sleep quality is higher and higher, and the pursuit of comfortable, high-quality and multifunctional mattresses becomes the trend of the times.
Far infrared rays have strong permeability and radiation power, have remarkable temperature control effect and resonance effect, are easily absorbed by an object and are converted into internal energy of the object, after the far infrared rays are absorbed by a human body, water molecules in the body can resonate to activate the water molecules, the intermolecular binding force of the water molecules is enhanced, biological macromolecules such as protein and the like are activated, biological cells are in the highest vibration energy level, the far infrared heat energy can be transmitted to a deeper part of the subcutaneous skin of the human body due to the resonance effect of the biological cells, the temperature of the deep layer rises below, and the generated heat is emitted from inside to outside.
The human body has the epidemic prevention capability for resisting various viruses and bacteria, creates a healthy body, and most importantly, enhances the natural immunity and the natural curative effect for various diseases, so that the physiological effect of hormones is vigorous. Small-particle-size air anions in the natural energy act on a human body, and a strong effect can be exerted. The negative ions can improve the natural ecological environment and purify the air; can regulate the intrinsic biological rhythm of human body and inhibit aging; activating the functions of liver and kidney and the peristalsis of intestine; the pH value of blood and body fluid is alkalescent, and the excretion of wastes and toxins in the body is promoted; improve lipid and sugar metabolism; promoting absorption and digestion, and generating metabolic hormone; activating NK cells, inhibiting proliferation of harmful bacteria and pathogenic bacteria, and preventing infection. Therefore, small-particle-size air negative ions are known as "vitamins of human air".
The mattress that possess far infrared ray and give off the anion simultaneously among the prior art is very few, realizes through the electrical heating mattress simultaneously that the mattress keeps warm and improves health effect and travelling comfort, then power consumption is big, and is energy-concerving and environment-protective not.
Disclosure of Invention
The invention aims to provide a functional mattress and a preparation method thereof, wherein a functional layer is arranged in the center of an emulsion layer, so that the cost is reduced, the softness of the mattress is improved, the prepared mattress has excellent mechanical strength and air permeability, a constant temperature layer containing energy storage materials is further arranged, heat is stored in the energy storage materials under the action of the heating layer, after power failure, the mattress can keep proper temperature for a long time, tourmaline and far infrared ceramics are promoted to emit negative ions and far infrared rays, a magnetic field beneficial to human health is formed, a good health care effect is realized for a user, the bearing capacity of the mattress can be further improved by the spring layer at the lowest layer, and the service life is prolonged.
The technical scheme of the invention is realized as follows:
the invention provides a functional mattress, which comprises a functional layer, a latex layer, a constant temperature layer, a heating layer and a spring layer, wherein the latex layer is arranged on the functional layer; the functional layer is embedded in the center of the latex layer to form a complete layer body, a constant temperature layer, a heating layer and a spring layer are sequentially arranged below the latex layer, a traditional Chinese medicine pillow is arranged at the intersection of the functional layer and the latex layer at the upper end, and the heating layer is a resistance wire layer and can be heated by electrifying; the constant temperature layer contains a phase change energy storage material; the functional layer is prepared from modified EPE foam; the modified EPE foam is prepared from the following raw materials in parts by weight: 10-20 parts of modified tourmaline, 5-10 parts of modified far infrared ceramic, 150 parts of low density polyethylene, 1-3 parts of foaming agent, 0.1-0.2 part of foam stabilizer and 0.01-0.02 part of initiator.
