Embodiment 1

[0098] In this example, 60 parts of polyether polyol, 32 parts of polymer polyol, 0.3 part of silicon surfactant 1 (Y-10366 produced by American Momentive Company), 0.1 part of Surfactant 2 (L-3001 produced by Momentive, USA), 2 parts of diethanolamine, 0.3 parts of A33, 0.5 parts of DMEA, 0.05 parts of C-225 and 4 parts of water are mixed evenly; add 0.5 parts TDI, 3 parts of polymerized MDI, and 1.5 parts of modified MDI were mixed and foamed, the foaming time was 8 seconds, and the temperature was 23°C; after the mold was preheated to 60°C, the foamed A and B The components were poured into the mold while stirring rapidly and evenly, and cooled at room temperature to obtain the cold-cured high-resilience foam with a core density of 41Kg / ㎡.

Embodiment 2

[0100] In this example, in parts by weight, 70 parts of polyether polyol, 35 parts of polymer polyol, 0.2 part of silicon surfactant 1 (Y-10366 produced by American Momentive Company), 0.05 part of Surfactant 2 (L-3001 produced by Momentive, USA), 1.5 parts of diethanolamine, 0.5 parts of A33, 0.7 parts of DMEA, 0.1 parts of C-225 and 6 parts of water are mixed evenly; add 1.5 parts TDI, 1 part of polymerized MDI, and 1.5 parts of modified MDI were mixed and foamed, the foaming time was 9 seconds, and the temperature was 25°C; after the mold was preheated to 62°C, the foamed A and B The components were poured into the mold while stirring rapidly and evenly, and cooled at room temperature to obtain the cold-cured high-resilience foam with a core density of 38Kg / ㎡.

Abstract

The present invention discloses a cold cure high resilient foam and a preparation method, the cold cure high resilient foam comprises components A and B, the component A comprises, by weight, 60-70 parts of polyether polyol; 30-35 parts of polymer polyol; 0.25-0.55 part of a silicone surfactant; 1-2 parts of a crosslinking agent; 0.85-1.3 parts of a catalyst; and 4-6 parts of water; the B component comprises, by weight, 0.5-1.5 parts of TDI (80 / 20); 1-3 parts of polymerized MDI and 0.5-1.5 parts of modified MDI, the water is used as a foaming agent, by adjusting the catalyst, the requirements of reduced density can be met, the density of the made cold cure high resilient foam is about 35KG / m<2>, the mechanical properties of the prepared cold cure high resilient foam can meet car and furniture seat back cushion requirements, so that the seat back cushion foam is further lightweight, and has very high availability and market value.

Description

technical field [0001] The invention relates to the field of foam products, in particular to a cold-cured high-resilience foam and a preparation method thereof. Background technique [0002] Cold-cured high-resilience foam has been widely used in the fields of car seats and furniture seats due to its high elasticity, high comfort, and high production efficiency. In recent years, the automobile and furniture industries have developed rapidly, and the market competition has also intensified. The sales prices of various models and furniture are getting lower and lower. Under the premise of ensuring the original performance, the production of foam products in the entire interior material, that is, foam, will be reduced. Cost has become a problem for many manufacturers. [0003] In order to reduce the foam density, many domestic raw material manufacturers usually use the method of adding foaming agents to the composite materials, such as adding foaming agents such as dichloromet...
