Abstract

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.

Description

technical field [0001] The application relates to the field of foamed cotton, more specifically, it relates to a healthy cotton and a preparation method thereof. Background technique [0002] Foamed cotton refers to materials with pores, such as polyvinyl chloride foamed materials, polyurethane foamed materials, etc. Its bubble structure can improve the flexibility of cotton materials, and it is easy to compound with other materials and has good processability. It is widely used in sofas, cushions, pillows and other fields. [0003] At present, with people's quality requirements for foamed cotton, fillers are added to improve the strength and toughness of foamed cotton, and anti-aging agents, ultraviolet absorbers and other additives are added to improve the aging resistance and yellowing resistance of foamed cotton. , to prolong the service life of the foamed cotton. [0004] However, the addition of fillers in the process of preparing foamed cotton materials at present w...
