The invention relates to a novel sports floor adhesive. The novel sports floor adhesive is prepared from the following raw materials including, by weight, 1-3 parts of polyethylidene maleic acid, 0.5-1 part of sodium diacetate, 5-9 parts of perfluoroalkyl ethyl methacrylate, 1-4 parts of methacrylamide, 10-18 parts of isocyanate, 2-5 parts of polyethylene, 10-15 parts of rosin, 5-8 parts of tetraethyl orthosilicate, 1-2 parts of propylene glycol methyl ether acetate, 5-9 parts of acrylate monomer, 15-20 parts of acetic ether, 2-7 parts of alkyl polyglucoside, 1-3 parts of putamen rubber powder, 1-2 parts of ammonium chloride, 8-12 parts of polyether polyol, 2-5 parts of plasticizer, 4-11 parts of tris(clorisopropyl)phosphate, 3-6 parts of sodium hydroxide and 3-10 parts of silica micropowder. The novel sports floor adhesive is free of toxicity and pollution, odorless, safe and environmentally friendly; the raw material source is rich, the production cost is reduced, the stability of the adhesive is improved by the aid of mutual cooperation of all the raw materials, and the adhesive is resistant to acid and alkaline corrosion; and the adhesive is good in elasticity, color retention and low-temperature flexibility and excellent in pressure resistance and is not volatile.
