Embodiment 1

[0030] Take the following components by weight, and use raw material tanks for batching: 90 parts of polyether polyol with a hydroxyl value of 230-306, 50 parts of isocyanate TDI80, 0.1 part of amine catalyst A33, and 0.3 parts of tin catalyst T9 1 part of silicone oil, 3 parts of sodium tetraborate, and 1 part of zinc oxide powder. The above-mentioned components are prepared in a raw material tank and then sent to the reaction kettle for mixing. The stirring speed is 3000r / min and the temperature is 21°C. Then the stirred mixture is sent to the foaming box for aging and film removal. 100s, process and cut the sponge obtained after aging and stripping into finished products.

Embodiment 2

[0032] Take the following components by weight, and use raw material tanks for batching: 110 parts of polyether polyols with a hydroxyl value of 230-306, 30 parts of isocyanate TDI80, 0.3 parts of amine catalyst A33, and 0.1 parts of tin catalyst T9 3 parts of silicone oil, 1 part of sodium tetraborate, and 3 parts of zinc oxide powder. The above-mentioned components are prepared in a raw material tank and then sent to the reaction kettle for mixing. The stirring speed is 5000r / min and the temperature is 23°C. Then the stirred mixture is sent to the foaming box for aging and stripping. The aging time is 150s, process and cut the sponge obtained after aging and stripping into finished products.

Embodiment 3

[0034] Take the following components by weight, and use raw material tanks for batching: 100 parts of polyether polyol with a hydroxyl value of 230-306, 40 parts of isocyanate TDI80, 0.2 parts of amine catalyst A33, and 0.2 parts of tin catalyst T9 2 parts, silicone oil 2 parts, sodium tetraborate 2 parts, zinc oxide powder 2 parts. The above-mentioned components are prepared in a raw material tank and then sent to the reactor for mixing. The stirring speed is 4000r / min and the temperature is 22°C. Then the stirred mixture is sent to the foaming box for aging and stripping. The aging time is 120s, process and cut the sponge obtained after aging and stripping into finished products.

Abstract

The invention discloses low-bounce ice-cold breathable sponge. The low-bounce ice-cold breathable sponge comprises the following components, by weight part, of 90-110 parts of polyether polyol, 30-50 parts of isocyanate, 0.1-0.3 part of amine catalyst, 0.1-0.3 part of tin catalyst, 1 part to 3 parts of stabilizers, 1 part to 3 parts of sodium tetraborate and 1 part to 3 parts of zinc oxide powder. The hydroxyl value of the polyether polyol is 230 to 306. The invention further correspondingly provides preparing process of the sponge. The preparing process comprises the steps of adding raw materials into a reaction kettle in proportion to be evenly mixed and stirred, sending the stirred and mixed raw materials into a foaming box to be cured and demoulded, cooling the cured and demoulded sponge for 24 hours and cutting the sponge into finished products. The sponge has good bounce, breathability and moisture penetrability and excellent mechanical property and also has the ice-cold effect.

Description

technical field [0001] The invention relates to the field of sponge processing and preparation, in particular to a low-rebound ice-cold breathable sponge and a preparation process thereof. Background technique [0002] Sponge is a type of polyurethane foam that falls specifically within flexible polyurethane foam. It has a porous honeycomb structure, so it has excellent softness, elasticity, water absorption, and water resistance. It is currently widely used in various industries such as sofas, mattresses, clothing, and flexible packaging. [0003] Low-rebound foam has excellent resilience and memory properties, so low-rebound pillows and mattresses made of it allow the body to rest in a natural, stress-free position. However, when the human body is in direct or indirect contact with the low-rebound sponge for a long time, the sponge will absorb heat and the temperature will rise accordingly, especially in hot weather, sitting on a sofa made of low-rebound sponge for a long...
