The invention discloses dust-free polyurethane mortar which is composed of a component A, a component B and a component C, and the mass ratio of the component A to the component B to the component C is (10-20): (10-20): (70-90). The component A comprises the following components in percentage by mass: 70-80% of polyol resin, 1-5% of an antibacterial agent, 1-5% of an auxiliary agent and the balance of water; the component B is an isocyanate curing agent; the component C is a filler. The hydroxyl value of the polyether polyol is 56-116 mgKOH/g, when the polyether polyol interacts with other substances in the components, the high ductility of the polyurethane mortar can be guaranteed, the high stain resistance can also be guaranteed, and in addition, the polyurethane mortar has the characteristics of low shrinkage, wear resistance, chemical corrosion resistance, high strength, high impact strength, good toughness, convenience in construction and the like.
本发明公开了一种无尘聚氨酯砂浆，所述无尘聚氨酯砂浆由A、B和C三组分组成，且A、B、C三组分的质量比为10～20：10～20：70～90；其中，A组分按质量百分比计，包括多元醇树脂70～80％，抗菌剂1～5％，助剂1～5％以及余量的水；B组分为异氰酸酯类固化剂；C组分为填料。在本发明中聚醚多元醇的羟值选择为56～116mgKOH/g，当其与组分中其他物质相互作用时，既可以保证该聚氨酯砂浆的高延展性，又可以保证高耐沾污性能，另外其还具有低收缩、耐磨、耐化学腐蚀、强度高，抗冲击强度大、韧性好和施工方便性等特点。
