The invention provides an antibacterial polyurethane material, a preparation method thereof and an automotive carpet. Raw materials for forming the antibacterial polyurethane material comprise a material A and a material B. The material A comprises first polyether polyol, second polyether polyol, a foaming agent, a catalyst, a foam stabilizer and quaternary ammonium salt, the pH of the first polyether polyol and the pH of the second polyether polyol are respectively and independently 7.5-8, the molecular weight of the first polyether polyol is 5800-6200, the molecular weight of the second polyether polyol is 7200-7700, and the molecular weight of the foaming agent is 5800-6200. The material B is prepared from diphenylmethane diisocyanate. The antibacterial polyurethane material has good bactericidal activity and high elasticity, and the automobile carpet made of the antibacterial polyurethane material is good in antibacterial effect, high in elasticity, low in volatile organic compound content, good in comfort level and high in safety.

    本发明提供了一种抗菌聚氨酯材料及其制备方法、汽车地毯。形成该抗菌聚氨酯材料的原料包括A料和B料,其中,A料包括第一聚醚多元醇、第二聚醚多元醇、发泡剂、催化剂、匀泡剂和季铵盐,第一聚醚多元醇和第二聚醚多元醇的pH分别独立地为7.5‑8,第一聚醚多元醇的分子量为5800‑6200,第二聚醚多元醇的分子量为7200‑7700,B料包括二苯基甲烷二异氰酸酯。该抗菌聚氨酯材料具有较好的杀菌活性和较高的弹性,用其制作的汽车地毯不仅抗菌效果好,而且弹性较高,挥发性有机物低,舒适度好,安全性高。
