Problems solved by technology

Both have their own advantages and disadvantages, but relatively speaking, the most fundamental thing is that the comprehensive performance of all aspects of water-based industrial coatings needs to be further improved.
The subsequent water-based industrial coatings use the compound of acrylic acid and water-based polyurethane as the main raw material, which not only inherits the advantages of acrylic products in weather resistance and good construction tolerance, but also improves the hardness of water-based industrial coatings, but the chemical properties and flexibility are still the same. not well resolved

Abstract

The invention relates to the field of chemical engineering, in particular to a graphene waterborne industrial coating and a preparation method thereof.The graphene waterborne industrial coating comprises emulsion, graphene water dispersion liquid, an ammonia neutralization agent, an antifoaming agent, a wetting agent, a flatting agent, colour paste, a thickening agent and water.The preparation method includes the steps that the emulsion and the graphene water dispersion liquid are added into a mixing kettle to be stirred till all materials are mixed to be uniform, and the mixture is obtained; the antifoaming agent, the wetting agent, the flatting agent and the colour paste are added in sequence, the mixture is stirred continuously till the mixture is mixed to be uniform, the water, the ammonia neutralization agent and the thickening agent are added slowly and stirred to be uniform, and a finished product of the graphene waterborne industrial coating is obtained.Through high stability and high strength capacity of the grapheme, abrasive resistance and hardness of the whole system are improved; meanwhile, the grapheme has excellent electrical conductivity, and electrochemical corrosion can be effectively relieved; a protection membrane can be formed due to the structural characteristics of the grapheme, and the abrasive resistance of the waterborne industrial coating is further improved.

Description

technical field [0001] The invention relates to the field of chemical industry, relates to a coating and a preparation method thereof, in particular to a graphene water-based industrial coating and a preparation method thereof. Background technique [0002] Objects are exposed to the atmosphere and are corroded by oxygen, moisture, etc., which can easily cause damage phenomena such as metal corrosion, wood decay, and cement weathering. However, coating the surface of the object to form a protective film can prevent or delay these damage phenomena The occurrence and development of various materials prolong the service life of various materials. Coatings can be coated on the surface of objects by different construction techniques to form a solid film with strong adhesion, certain strength and continuous. But at the moment, environmental protection issues are becoming a "big problem" facing the coatings industry. The volatile organic compounds released during the paint paintin...
