Description

Viscoelastic cushion

This work is about a cushion structure, especially a viscoelastic cushion that can increase the tensile strength and can be spliced into a large area or longer.

Due to the change of social patterns, modern people generally lack exercise, and often maintain the same posture for a long time, and it is prone to back pain after a long time. In addition to the regular movement of the limbs to stretch the bones, maintaining the correct posture and how to get the proper support of the body are ways to prevent the above problems. For the purpose of health and comfort, you can see a variety of cushions or cushions for supporting the human body, such as mattresses, cushions, cushions and pillows. The function of the cushion should be, in addition to providing soft comfort, it should also have the effect of dispersing weight and fully supporting the weight of the human body.

Known cushions provide support, bulk and softness through different materials and structural designs. Common materials include: foam, memory foam (polyurethane), natural cotton, latex, and viscoelastic (viscous elastomer) ), these known materials each have different characteristics and applicable conditions.

Viscous elastomer is a polymer compound with excellent pressure conductivity and excellent impact absorption. It can also be a polymer copolymer, which can be thermoplastic, such as SEBS (hydrogenated styrene butadiene copolymer). Or Thermoplastic Polyurethane (TPU) is a flexible viscoelastic colloid formed, and its hardness can be adjusted as needed, with low backlash elasticity, so it is especially suitable for making A highly flexible pad, so more and more padded gel materials have been used. However, the viscoelastic body has poor ductility, and a large area or a long viscoelastic material is easily broken, and it is difficult to handle due to its heavy weight. Therefore, a large area or a long length is directly produced from a viscoelastic material. Viscoelastic soft Pads, which have considerable difficulties in implementation, need to be further overcome.

This creation proposes a viscoelastic cushion that increases the tensile strength of the viscoelastic cushion.

Please refer to FIG. 1 for a flow chart of the steps of an embodiment of the method for manufacturing a viscoelastic cushion, comprising: 1-1. preparing a foam layer having a plurality of pores, which are soft and breathable. And the effect of the bulk pressure; 1-2. A mesh body 20 is adhered to one side surface of the foam layer, and the net body 20 is a kind of bullet The structure of the mesh 21 woven by the fiber (see "Fig. 3"), the specific embodiment should select the wire with better tensile strength, so that the mesh body 20 can be front, back or left, right or front and back. And stretching the left and right sides to make the net body 20 have the stretching property; and 1-3. providing a viscoelastic body on the surface of the net body, and directly bonding the viscoelastic body to the net body through casting or coating. And the foam layer is condensed into one.

The above viscoelastic system is a gel or thermoplastic polyurethane (TPU). The gel formulation contains mineral oil, so it cannot be directly combined with other foam materials and other foam layers, and TPU and foam need to use a solvent-based adhesive material that is unfavorable to the human body, but this ( Solvent-based adhesive materials are often detrimental to the human body system and the environment, and are prone to pollution and environmental problems. Through the embodiment of the method steps described above, the water-based adhesive generally free from pollution and environmental problems can be first bonded to the mesh body and the foam layer, and then the viscoelastic body is directly combined with the mesh body or the foam layer. Together, a viscoelastic cushion is formed to solve the problem that the viscoelastic body is not easily bonded directly to the foam layer.

One of the embodiments of the above method steps is to heat the viscoelastic material to a molten fluid state (generally, the viscoelastic material is heated to about 200 ° C to 240 ° C to be melted into a fluid state), and then the molten fluid state is obtained. The viscoelastic material is poured or cast or coated on the mesh surface of one side surface of the foam layer. Since the foam layer is a porous structure, the viscoelastic material in the molten fluid state can be covered with the mesh after covering the mesh body. The body is condensed together, and some of the viscoelastic material in the molten state will penetrate into the pores of the foam layer, and the viscoelastic body formed by cooling the viscoelastic material in the fluid state can be combined with the mesh body and the bubble. The cotton layers are integrated into one body, wherein the two axial directions of the plane of the net body can be stretched and deformed, and have sufficient tensile strength, since the viscoelastic body directly condenses with the net body, and the viscoelasticity is increased through the net body. The tensile strength of the body cushion and the foam layer further solves the problem that the viscoelastic body and the foam layer material are easily broken when stretched or handled.
