Technical Field
The invention relates to a functional mattress and a preparation method thereof, in particular to a konjac glucomannan functional mattress and a preparation method thereof, belonging to the technical field of daily necessities.
Background
in recent years, the quality of household articles and the functions thereof become important indexes for people to enjoy life and improve the quality of life. Having good sleep is a problem that people in every age stage pay attention to, and the choice of mattress is closely related to the quality of sleep. Most of the mattresses in the market at present are mainly made of traditional cotton or sponge. The traditional cotton or sponge mattress is easy to mildew and grow insects when meeting moisture, and even some cotton or sponge mattresses are compacted, collapsed and deformed, so that the softness is sharply reduced. The over-soft cotton mattress is not good for the growth and development of children skeletons, and can relieve the pressure of shoulders of adults, thus aggravating the burden of waist to cause diseases such as lumbar muscle strain, lumbar disc herniation and the like. The konjac glucomannan gel has good elasticity and toughness, can realize slow rebound as an inner core of a mattress, and the raw materials are tightly bonded with each other, so that the powder of the traditional Chinese medicine components can be well and uniformly fixed in the raw materials, and the medicinal effect is improved. The special physical structure can completely block fine dust and mites. Compared with the traditional mattress, the utility model has more and better functional characteristics for human body.
the invention patent 'a negative potential physiotherapy mattress' (application date: 207.11.22) with the application number of 201711175471.6 introduces a negative potential physiotherapy mattress, wherein a bamboo charcoal emulsion layer and a negative potential generation layer of the mattress are electrically connected with a control device to realize the potential physiotherapy function, a pressure sensor and the negative potential generation layer are arranged in a mattress body, and when the pressure sensor detects that a person lies on the mattress body, a negative potential generation module works to enable a negative potential wire to generate negative potential, so that the body of a sleeper absorbs the negative potential, and the metabolism of the body is improved. However, the negative potential physiotherapy mattress is not made of all natural materials, and has low safety performance, poor moisture resistance and weak durability.
The invention patent with application number 201610361232.9, a manufacturing method of a honeycomb cotton mattress (application date: 2016.05.26), introduces a manufacturing material of a cotton layer, which is a bionic honeycomb cotton product and has various effects of good strength, fluffiness, heat preservation, heat dissipation and the like. Be provided with rather than sliding fit's radiator fan on the litter of mattress both sides, this radiator fan's air outlet sets up with the bottom on the cotton layer directly over it relatively, is provided with temperature sensor on radiator fan, and ventilation effect is stronger, and ventilation effect is better moreover. However, the anti-moisture capability is weak, the acarid is easy to grow, the manufacturing process is complex, the cost is high, and the popularization is not easy.

the invention relates to a high-density and non-deformable multifunctional mattress of konjac glucomannan, wherein nano pores are formed by konjac glucomannan gel, and the biological polysaccharide porous material has very high porosity and very large specific surface area, has very good buffering performance and flexibility, has strong supporting force and has the characteristic of slow rebound; the konjac glucomannan used as the raw material has wide sources and high yield, is mainly distributed in the south of clouds, nobility, Sichuan, Shaanxi and the west of Hubei in China, and is most abundant in the mountain areas around Sichuan basins. It is readily available and inexpensive. The small molecule, high density structure increases flexibility and moisture resistance. The special material has certain protection effect on human vertebra, and the high-density molecular structure makes the human vertebra more fit with the body shape, increases the comfort degree, and improves the sleep quality. Therefore, the mattress has better antibacterial property, moisture resistance and flexibility. The prepared konjac glucomannan functional mattress is subjected to the following performance tests:
(1) Slow rebound resilience
the artificial (body weight greater than 80 kg) was used for 30 days and tested using thickness test.
(2) Moisture resistance
The water content of the functional mattress inner core of konjac glucomannan and the traditional mattress (cotton and sponge) is detected and compared.
(3) hardness and softness
And (3) detecting by using a mattress hardness tester (a spherical steel plate with a convex bottom), recording a force value-displacement of a loading curve, and checking the hardness.
(4) Durability
The konjac glucomannan functional mattress core and the traditional mattress were passed through a hexagonal roller weighing 240 pounds for 10,000 cycles.
(5) flame retardancy
The lighted cigarette ends or flames are closely placed along the vertical surface and the horizontal surface of the mattress, and whether the inner core is smoldering or flaming is detected.
The results of the comparison of the konjac glucomannan functional mattress of the invention with the similar products sold in the market in slow rebound resilience, moisture resistance, hardness, durability and flame retardance are shown in table 1.
TABLE 1 comparison of the performance of the functional mattress of Konjac glucomannan of the invention with the performance of the same type of products on the market
Through the comparison tests, the konjac glucomannan functional mattress has excellent performances, and the indexes of the konjac glucomannan functional mattress exceed those of the commercially available traditional mattress, so that the konjac glucomannan functional mattress can replace the existing mattress.
