Polyurethane modified foam concrete and preparation method thereof
The invention discloses polyurethane modified foam concrete and a preparation method thereof. The polyurethane modified foam concrete is prepared from the following raw materials in parts by weight: 400-800 parts of ordinary Portland cement, 6-50 parts of polyurethane emulsion, 2-5 parts of a foaming agent, 0.02-0.04 part of a foam stabilizer and 180-300 parts of water. The preparation method comprises the following steps: diluting the foaming agent in a ratio of 1: 30, adding the foam stabilizer, and uniformly stirring to prepare a foaming agent aqueous solution; uniformly mixing the polyurethane emulsion with water, and stirring with cement to form cement paste; stirring the foaming agent aqueous solution at high speed to prepare foam; and uniformly mixing the prepared foam with cement paste to prepare the polyurethane modified foam concrete. According to the prepared polyurethane modified foam concrete, the mechanical property and the energy absorption property of the foam concrete are improved.
本发明公开了一种聚氨酯改性泡沫混凝土及制备方法，包括以下重量份的原料：普通硅酸盐水泥400～800份，聚氨酯乳液6～50份，发泡剂2～5份，稳泡剂0.02～0.04份，水180～300份；制备方法为：将发泡剂以1:30的比例稀释，掺入稳泡剂搅拌均匀，制备出发泡剂水溶液；将聚氨酯乳液与水混合均匀，再与水泥搅拌成水泥浆体；高速搅拌发泡剂水溶液，制备成泡沫；将制备好的泡沫与水泥浆体混合均匀制得聚氨酯改性泡沫混凝土。本发明制备出的聚氨酯改性泡沫混凝土提高了泡沫混凝土的力学性能与吸能性能。
