The invention relates to the field of chemical adhesives, in particular to a floor glue. The floor glue is composed of the following substances by weight: 25-35 parts of white latex, 30-40 parts of organic silicon resin, 5-10 parts of talcum powder, 5-8 parts of zeolite powder, 3-8 parts of sorbic acid, 15-20 parts of quartz powder, 15-20 parts of sodium hydroxide, 25-30 parts of urea, 15-25 parts of diethylene glycol, 5-8 parts of melamine, 15-25 parts of nano-silica, 5-10 parts of a toughening agent, 8-12 parts of a curing agent, 35-45 parts of castor oil, 5-8 parts of a catalyst, 15-25 parts of polyvinyl alcohol, 5-10 parts of a flame retardant, 8-12 parts of a wear-resistant agent, 0.5-5 parts of a defoaming agent, and 50-70 parts of deionized water. The floor glue provided by the invention has the characteristics of reasonable raw material cost, no pollution, minimum damage to human body health, good bonding properties, stable performance, and good waterproof properties. The wear-resistant agent and nano-silica are added into the floor glue to increase the surface area of the floor glue so as to greatly enhance the wear resistance of the floor, and the flame retardant material is added to greatly increase the safety factor of the floor. Being safe and environment-friendly, the floor glue is very promising.
