Embodiment 1

[0038] see figure 1 with figure 2 , a seat back cushion core, including polyurethane shaped cotton skeleton 1 and embedded in the polyurethane shaped cotton skeleton 1 in the sponge core 2 and U-shaped pearl cotton outer core 3. Wherein, the hardness of the polyurethane shaped cotton skeleton 1 is greater than the hardness of the U-shaped pearl cotton outer core 3 , and the hardness of the U-shaped pearl cotton outer core 3 is greater than the hardness of the sponge inner core 2 .

[0039] see figure 1 with figure 2 , The polyurethane shaped cotton skeleton 1 includes a frame body 11 and a flange 12 that is arranged around the frame body 11 in the circumferential direction. The frame body 11 is provided with an installation channel 13 penetrating through the sides and upper and lower surfaces of the frame body 11 . The sponge inner core 2 is fixedly embedded in the installation through groove 13 by an adhesive. The opening of the installation channel 13 is opened on the...

Embodiment 2a

[0043] A method for manufacturing a seat back cushion core, comprising the steps of:

[0044] Step1, foam molding polyurethane stereotyped cotton skeleton 1, U-shaped pearl cotton outer core 3 and sponge inner core 2 through mold foaming;

[0045] Step2, coat the commercially available acrylic elastic adhesive in the installation channel 13 and the U-shaped channel of the U-shaped pearl cotton outer core 3, purchased from Shanghai Derun Petrochemical Co., Ltd.;

[0046] Step 3: Embed the sponge inner core 2 in the installation channel 13, and embed the U-shaped pearl cotton outer core 3 in the U-shaped channel. After the adhesive is cured, the seat back cushion core is obtained.

Embodiment 2b

[0048] A method for manufacturing a seat back cushion core, comprising the steps of:

[0049] Step1, foam molding polyurethane stereotyped cotton skeleton 1, U-shaped pearl cotton outer core 3 and sponge inner core 2 through mold foaming;

[0050] Step2, apply commercially available epoxy resin rigid glue in the installation channel 13 and the U-shaped channel of the U-shaped pearl cotton outer core 3, purchased from Shanghai Derun Petrochemical Co., Ltd.;

[0051] Step 3: Embed the sponge inner core 2 in the installation channel 13, and embed the U-shaped pearl cotton outer core 3 in the U-shaped channel. After the adhesive is cured, the seat back cushion core is obtained.

Abstract

The invention discloses a back cushion core of a seat and a manufacturing method of the back cushion core, aiming at solving the problem that existing commercial back cushions, since polyurethane forming cotton is relatively high in cost, are high in cost. According to the technical scheme, the back cushion core is characterized by comprising a polyurethane forming cotton skeleton, a mounting through slot which is arranged in the polyurethane forming cotton skeleton and a U-shaped semi-slot which is arranged around the mounting through slot and communicates with the mounting through slot, wherein a sponge inner core is embedded in the mounting through slot; a U-shaped pearl cotton outer core is embedded in the U-shaped semi-slot; the sponge inner core and the U-shaped pearl cotton outer core are bonded on the polyurethane forming cotton skeleton via adhesives; and the polyurethane forming cotton skeleton is greater than the sponge inner core and the U-shaped pearl cotton outer core inhardness. Under the circumstance of guaranteeing same comfort with back cushions which are integrally manufactured by polyurethane forming cotton, other materials can be used for replacing the polyurethane forming cotton, so that cost of the back cushion can be reduced.

Description

technical field [0001] The invention relates to daily necessities, in particular to a seat back cushion core and a preparation method thereof. Background technique [0002] Cushions are indispensable objects in daily life, and they are widely used, such as on beds, sofas, and car seats. For people who sit for a long time, such as drivers and white-collar workers, if they keep sitting for a long time, their lumbar spine is prone to soreness. Sometimes they do not pay attention to their sitting posture and maintain a bad sitting posture for a long time, which will cause damage to the lumbar spine and easily cause lumbar spondylosis. Therefore, a cushion is often placed on car seats, sofas, and office seats to adjust the position of the lumbar spine and the seat, obtain a more comfortable angle, and reduce lumbar fatigue. [0003] For example, the cushion disclosed by the patent with the authorized announcement number of CN202941745U includes a cushion core and a jacket. The c...
