Preparation method of bio-based polyurethane foam soil
The invention relates to a foam soil material, in particular to a preparation method of bio-based polyurethane foam soil. The invention relates to a preparation method of bio-based polyurethane foam soil, which comprises the following steps: (1) cleaning, airing and crushing recycled polyurethane foam to obtain polyurethane foam particles; (2) airing and sieving the fine aggregate to obtain air-dried fine aggregate; (3) carrying out amplification culture and centrifugal concentration on the bacillus pasteurii to obtain a bacillus pasteurii suspension; and (4) doping fly ash into the air-dried fine aggregate, adding the bacterial suspension, uniformly mixing, adding polyurethane foam particles, a nutrient source and a calcium source, uniformly mixing, filling into a mold, and curing to obtain the bio-based polyurethane foam soil. The method is small in soil material consumption, low in cost, excellent in performance and free of secondary pollution.
本发明涉及泡沫土材料，尤其涉及一种生物基聚氨酯泡沫土的制备方法。一种生物基聚氨酯泡沫土的制备方法，包括以下步骤：（1）将回收聚氨酯泡沫清洗晾干、粉碎，获得聚氨酯泡沫颗粒；（2）将细骨料晾晒过筛，获得风干细骨料；（3）将巴氏芽孢杆菌扩大培养，离心浓缩，获得巴氏芽孢杆菌悬液；（4）在风干细骨料中掺入粉煤灰，加入菌悬液，混合均匀，加入聚氨酯泡沫颗粒、营养源、钙源，混合均匀，装模养护，获得生物基聚氨酯泡沫土。本发明土料用量小，成本低、性能优良，且无二次污染。
