Sponge for mattresses and preparation method thereof

Abstract

The invention discloses a sponge for mattresses. The sponge for mattresses includes a sponge body, the sponge body is internally provided with a placement groove, the placement groove is internally provided with a plurality of spring mechanisms in rectangular arrangement, and each spring mechanism comprises a first plastic spring, a second plastic spring and a third plastic spring that are arranged from top to bottom in order, and the elastic forces of the first plastic spring, the second plastic spring and the third plastic spring increase in turn. The sponge body comprises the following rawmaterials by weight: 100-120 parts of a polyether polyol composition, 50-70 parts of polyester, 30-50 parts of toluene diisocynate, 9-18 parts of tourmaline powder, 20-40 parts of bamboo and wood fiber powder, 3-9 parts of graphene, 5-10 parts of carbon black, 1-10 parts of silicon resin, and 20-40 parts of a Chinese medicinal composition. The invention also puts forward a preparation method of the sponge for mattresses. The sponge for mattresses provided by the invention has the advantages of low cost, and coexistence of supportiveness and softness, reduces metal products compared with pure spring mattresses, enhances comfort, and has simple making process and good health care effect, thus being suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of mattress sponges, in particular to a mattress sponge and a preparation method thereof. Background technique [0002] The sponge is named after the algae in the ocean, which is characterized by its softness and elasticity. Most of the sponges we use in our lives are formed by foaming chemical products such as rubber, polyester, and polyether. Sponge has a wide range of uses, and is widely used in seats, mattresses, sofas, medical and health care products, and decorative products based on its thermal insulation, sound insulation, and impact resistance properties. The production of sponge in the world is very large, and it is an industrial field that cannot be ignored. But the sponge of prior art mainly plays heat preservation and anti-shock effect, along with the raising of people's demand and use standard, higher requirement is also proposed to sponge, such as requiring more functions and the health that...

Problems solved by technology

But the sponge of prior art mainly plays heat preservation and anti-shock effect, along with the raising of people's demand and use standard, higher requirement is also proposed to sponge, such as requiring more functions and the health that is beneficial when using.

[0003] In addition, existing mattress products are usually pure spring mattresses or polyurethane cotton mattresses. Both types of mattresses have their own advantages and disadvantages. Spring mattresses have excellent support, but due to the presence of metal springs, they are noisy, easy to break the surface, After a long time, the problem of unequal mattresses, pure polyurethane mattresses do not have the above problems, but the support can not meet the needs of everyone
