Embodiment 1

[0015] Based on 100 parts by weight of the mixture of polyether polyol and polymer polyol, add 33.5 parts of toluene diisocyanate, 0.8 part of polysiloxane polyether copolymer, 0.2 part of triethylene diamine solution, and 0.06 part of stannous octoate , 1.9 parts of foaming agent water. Among them, the above-mentioned polyether polyols are two kinds of Mn700 polyether polyols and Mn3000 polyether polyols, and the material ratios in 100 parts are respectively: 60 parts of Mn700 polyether polyols, 20 parts of Mn3000 polyether polyols, and Mn6000 polymers 20 parts of polyols.

[0016] The air-permeable slow-rebound sponge made from the above raw materials has a porosity of 95%. Press the sponge with your hands, and you can obviously feel the air circulation; blowing air from one side of the 40cm thick sponge, you can feel the airflow immediately on the other side.

Embodiment 2

[0018] Based on 100 parts of the mixture of two polyether polyols and polymer polyols, add 35.8 parts of toluene diisocyanate, 1 part of polysiloxane polyether copolymer, 0.16 parts of triethylenediamine solution, 0.08 parts of stannous octoate, and foam 2.2 parts of agent water. Among them, the above-mentioned polyether polyols are two kinds of Mn700 polyether polyols and Mn3000 polyether polyols, and the material ratios in 100 parts are respectively: 60 parts of Mn700 polyether polyols, 15 parts of Mn3000 polyether polyols, and Mn6000 polymer 25 parts of polyols.

[0019] The air-permeable slow-rebound sponge made from the above raw materials has a porosity of 97%. Press the sponge with your hands, you can obviously feel the air flow quickly, and you can hear the sound of air flow; blow air from one side of the 50cm thick sponge, and you can feel the air flow through the other side immediately; the human body lies flat on the sponge, No stuffy feeling.

Embodiment 3

[0021] Based on 100 parts of the mixture of two polyether polyols and polymer polyols, add 35.8 parts of toluene diisocyanate, 0.8 parts of polysiloxane polyether copolymer, 0.2 parts of triethylenediamine solution, 0.06 parts of stannous octoate, and foam 2.05 parts of potion water. Among them, the above-mentioned polyether polyols are two kinds of Mn700 polyether polyols and Mn3000 polyether polyols, and the material ratios in 100 parts are respectively: 65 parts of Mn700 polyether polyols, 30 parts of Mn3000 polyether polyols, and Mn6000 polymers 5 parts polyol.

[0022] The air-permeable slow-rebound sponge made of the above raw materials has a porosity of 98%. Press the sponge with your hands, you can obviously feel the air flow quickly, and you can hear the sound of air flow; blow air from one side of the 50cm thick sponge, and you can feel the air flow through the other side immediately; the human body is wrapped in the sponge, can Breathe freely.

Abstract

The invention mainly discloses a novel ventilated slow-resilience sponge, in particular relates to a ventilated slow-resilience sponge which ensures the aperture ratio of a product by adjusting raw materials and the proportioning of a product, so that the aperture ratio of the product is improved to over 95 percent without using a pore-forming agent or pore-forming silicone oil, and the ventilation property of the product is improved. When the ventilated slow-resilience sponge is used, a human body contacts the product and obviously feels that the product is floppy; and the product is more comfortable after being used for a long time, particularly in muggy summer.

Description

technical field [0001] The invention relates to a slow-rebound sponge, in particular to an air-permeable slow-rebound sponge synthesized without using a pore-opening agent or silicone oil with an opening ratio greater than 70%. Background technique [0002] Since the slow rebound sponge was developed by the United States Space Development Agency in the 1950s, most of the products produced have a low opening rate, generally less than 70%. In the production process, cell opener or open cell silicone oil is used, and the product has low air permeability and poor comfort. Contents of the invention [0003] The main task of the present invention is to provide a novel air-permeable slow-rebound sponge, in particular to a product that does not use a cell-opening agent or silicone oil to increase the porosity of the product so as to improve the gas permeability of the product. [0004] In order to solve the above technical problems, the components and proportions of a novel breat...
