| description | The invention relates to the field of foamed cotton, in particular to healthy cotton and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing 60-70% of polyether polyol, 2-8% of polymer polyol and 0.01-0.05% of water to obtain a mixture I; uniformly mixing 20%-30% of isocyanate, 0.05%-0.20% of silicone oil, 0.01%-0.10% of a catalyst and 3%-6% of other auxiliaries to obtain a mixture II; heating the mixture I to 50-70 DEG C, adding the mixture II while stirring, reacting for 2-3 hours after adding, then putting into a mold, curing, demolding and standing to obtain the healthy cotton. The healthy cotton is uniform in foam hole, stable, soft and comfortable, has excellent rebound resilience and air permeability, still keeps excellent performance after being subjected to high-temperature mold pressing processing, and can be suitable for products such as female underwear and bra cotton, infant products, furniture pads or pillows and the like.
