Abstract

The invention provides environment-friendly waterborne coating. The environment-friendly waterborne coating is characterized by being prepared from the components in parts by weight: 45 to 55 parts ofa modified polyethylene glycol methacrylate type film-forming polymer, 20 to 30 parts of a pyrrolidinone type ion co-polymer, 1 to 3 parts of a flatting agent, 10 to 15 parts of nano titanium dioxide, 2 to 5 parts of a de-foaming agent and 20 to 30 parts of water. The invention further discloses a preparation method of the environment-friendly waterborne coating; the preparation method comprisesthe following steps: mixing all the components in percentage by mass in sequence and stirring; raising the temperature to 85 to 90 DEG C under a stirring condition and carrying out heat insulation for1 to 2h; and then filtering, packaging and storing to obtain the environment-friendly waterborne coating. The environment-friendly waterborne coating prepared by the preparation method is more convenient to construct, has better fullness, lower production cost and more excellent comprehensive performance and is more green and environmentally friendly to use.

Description

technical field [0001] The invention relates to the technical field of coatings and preparation methods thereof, in particular to an environmentally friendly water-based coating and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of industry, environmental pollution and energy problems have become increasingly serious, which have become important factors restricting social development. Countries around the world are currently taking strict measures to limit the emission of volatile organic compounds. Green environmental protection materials have entered people's sight and gradually become an indispensable part of people's lives. In order to adapt to this trend, water-based coatings emerged as the times require and have become the mainstream direction of the development of the modern coatings industry. [0003] Water-based coatings use acrylic acid as the main raw material and use water as the dispersion medium and thin...
