NOVELTY - Environment-friendly floor paint comprises 50 to 80 pts. wt. epoxy resin, 10 to 15 pts. wt. pigment, 15 to 20 pts. wt. Pittosporum tobira, 5 to 10 pts. wt. graphene, 5 to 10 pts. wt. tung oil, 5 to 8 pts. wt. aggregate, 3 to 5 pts. wt. trihydroxypropane, 1 to 3 pts. wt. thickener, 2 to 3 pts. wt. defoamer, 1 to 3 pts. wt. leveling agent and water. Environment-friendly floor paint is prepared by pre-treating aggregate, so that the aggregate fineness modulus is 2.4 to 2.8. The Pittosporum tobira leaves, husks or seeds are soaked in deionized water for 35~40h, filtered, filter residue is pressed to obtain the pressing liquid. The pressing liquid and the filtrate are mixed to obtain a extract, and the mass ratio of the extract to the deionized water is 1:2 to 1:5. USE - Environment-friendly floor paint. ADVANTAGE - The environment-friendly floor paint has fast drying speed, improved hardness of the paint film, and good bearing capacity and wear resistance. DETAILED DESCRIPTION - The tung seeds are dried, the water content is 1 to 4% followed by shelling and purifying, pulverizing to a particle size of 35 to 45 mesh, and putting into the extraction kettle, setting the temperature to 40 to 60 degrees C, and the pressure to 25 to 35 MPa. The extraction is carried out, the extraction is carried out for 35 to 45 minutes, then the temperature is adjusted to 25 to 35 degrees C, the pressure is 10 to 15 MPa, and the tung oil is extracted and used. The epoxy resin and the extract are uniformly mixed, and then added to the trihydroxypropane, uniformly mixed, sonicated at 36 to 38 kHz for 35 to 40 minutes to obtain a mixture A. The graphene and the aggregate are uniformly mixed, and then a thickener, an defoamer, a leveling agent are added, and the mixture is uniformly mixed, and ultrasonically irradiated at 36 to 38 kHz for 35 to 40 minutes to obtain a mixture B. Tung oil and pigment are mixed, sonicated at 36 to 38 kHz for 35 to 40 minutes to obtain a mixture C. A, B, and C mixtures are uniformly mixed, and vacuum-rotated at 60-65 degrees C to a water content of 9 to 10%, floor paint. Spray bottle packaging is performed to obtain the finished product.
