Abstract

The invention relates to a terrace coating and a preparation method thereof, and belongs to the technical field of building coatings. The terrace coating is prepared from, by weight, 40-50 parts of polytetrafluoroethylene, 10-16 parts of epoxy resin, 1-5 parts of nano-zinc oxide, 30-38 parts of precipitated barium sulphate, 2-6 parts of talcum powder, 1-5 parts of reactive diluent, 1-5 parts of antioxidant and 1-5 parts of defoaming agent. The preparation method includes the steps that the raw materials are evenly mixed and then are ground through a sand mill till the fineness is 5-10 microns to be placed in a reaction container, and the temperature of the reaction container is 70-80 DEG C to be kept for 60-65 minutes; afterwards, the reaction container is cooled to be at an indoor temperature, ultrasonic treatment is conducted for 40-50 minutes, filtering is performed through cloth of 120-150 microns, the pH of emulsion is adjusted to be 9.0-10.0 through sodium hydroxide, and accordingly the finished product can be obtained. The terrace coating has excellent chemical medium corrosion resistance, weather resistance, oil resistance, water resistance, good mechanics mechanical performance and construction performance and the like. Meanwhile, attractiveness, slipping resistance and environment-friendly safety are achieved, and no poison and harm are caused to human bodies and the environment; the preparation cost is low, and the cost performance is high.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a floor coating and a preparation method thereof, belonging to the technical field of architectural coatings. Background technique [0002] Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called a paint. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. The general composition of coatings: including film-forming substances, pigments and fillers, solvents, and additives. [0003] Driven by downstream industries, China's coatings industry is growing day by day, and architectural coatings, one of its branches, have also achieved consid...
