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...
