Embodiment 1

[0032] The low-temperature perceptual memory foam based on air and structural support provided in this embodiment is made of the following raw materials in parts by weight: 50-90 parts of polyether polyol, 10-40 parts of polymer polyol, 35-50 parts Parts of diphenylmethane diisocyanate, 10-20 parts of water, 0.5-3 parts of foam stabilizer, 0.2-5 parts of cross-linking agent, 0.5-4.5 parts of chain extender, 3-6 parts of opening agent, 1-3 parts of foam stabilizer, 1-3 parts of polysiloxane polyether copolymer, 0.3-1.3 parts of organotin catalyst and 0.5-1.5 parts of amine catalyst.

[0033] The polyether polyol is a kind of chemical, which is an oligomer of terminal hydroxyl groups, the hydroxyl groups on the main chain are connected by ether bonds, and the initiators are low molecular weight polyols, polyamines or compounds containing active hydrogen , formed by ring-opening polymerization with alkylene oxide under the action of a catalyst, and is commonly used in the manufac...

Embodiment 2

[0052] The difference between this example and Example 1 lies in that this example provides the specific content of each raw material in the low-temperature perceptual memory foam based on air and structural support.

[0053] The low-temperature perceptual memory foam based on air and structural support provided by this embodiment is made of the following raw materials in parts by weight: 60 parts of polyether polyol, 30 parts of polymer polyol, 40 parts of diphenylmethane di Isocyanate, 15 parts of water, 2 parts of foam stabilizer, 1.5 parts of crosslinking agent, 2 parts of chain extender, 4 parts of cell opener, 2 parts of foam stabilizer, 2 parts of polysiloxane Ether copolymer, 0.8 part of organotin catalyst and 1 part of amine catalyst.

Embodiment 3

[0055] The difference between this embodiment and the first embodiment is that in this embodiment, the components of the raw materials in the low-temperature sensitive memory foam based on air and structural support are taken as the maximum values ​​in the first embodiment.

[0056] The low-temperature perceptual memory foam based on air and structural support provided in this embodiment is made of the following raw materials in parts by weight: 90 parts of polyether polyol, 40 parts of polymer polyol, 50 parts of diphenylmethane Diisocyanate, 20 parts of water, 3 parts of foam stabilizer, 5 parts of crosslinking agent, 4.5 parts of chain extender, 6 parts of cell opener, 3 parts of foam stabilizer, 3 parts of polysiloxane Polyether copolymer, 1.3 parts of organotin catalyst and 0.5-1.5 parts of amine catalyst.

Abstract

The invention discloses a low-temperature sensitive memory sponge based on air and structural support and a preparation method thereof, wherein the low-temperature sensitive memory sponge based on airand structural support is made of the following raw materials in parts by weight: 50-90 parts of polyether polyol, 10-40 parts of polymer polyol, 35-50 parts of diphenylmethane diisocyanate, 10-20 parts of water, 0.5-3 parts of foam homogenizer, 0.2-5 parts of crosslinking agent, 0.5-4.5 parts of chain extender, 3-6 parts of opening agent, 1-3 parts of foam stabilizer, 1-3 parts of polysiloxane polyether copolymer, 0.3-1.3 parts of organotin catalyst and 0.5-1.5 parts of amine catalyst. The invention has the advantage that it still has better resilience at low temperature.

Description

technical field [0001] The invention belongs to the technical field of memory foam manufacturing, and in particular relates to a low-temperature perceptual memory foam based on air and structural support and a preparation method. Background technique [0002] Memory foam is a polyurethane sponge with slow resilience characteristics. Because of its remarkable slow resilience, it can effectively absorb impact force, reduce vibration, and adapt to external pressure through stress relaxation. Therefore, it is a pillow, seat cushion, and mattress. The preferred material for other bedding. [0003] However, the existing memory foam is sensitive to the temperature of use and tends to harden in winter, especially below 8 degrees Celsius. The softness and resilience of the memory foam are severely lost and become stiff, which seriously affects the comfort of use. Doesn't work as memory foam should. Contents of the invention [0004] In order to solve the problem that the existing...
