Problems solved by technology

[0004] However, affected by the limitations of epoxy technology itself, water-based epoxy coatings usually have two types of disadvantages during use: 1) Epoxy coatings with a long potency period (up to 4 hours or more), the drying speed is too slow ; 2) Epoxy coatings with faster drying speed, the pot life is too short (less than 2 hours)

Abstract

The invention provides quick-drying type water-borne mental corrosive-resistant paint and a preparation method thereof. The quick-drying type water-borne mental corrosive-resistant paint is prepared from an ingredient A and an ingredient B, wherein the ingredient A is prepared from water-borne acrylic resin emulsion and water-borne modified fatty amine curing agent blended resin; the ingredient B is epoxy resin. A water-borne epoxy technology and a water-borne acrylic technology are creatively compounded and applied, so that a product has a long activation period and fast drying speed; the construction is convenient; healthy and environment-friendly effects are achieved; a paint film has the performance advantages such as high hardness, high impact resistance and excellent adhesive force; the quick-drying type water-borne mental corrosive-resistant paint can be widely applied to decoration and protection of metal substrates such as galvanized plates, tinplate, stainless steel and aluminum-plastic plates.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a quick-drying water-based metal anti-corrosion coating and a preparation method thereof. Background technique [0002] With the wheels of the modern industrial revolution rolling forward, resource and environmental issues have become a pair of major contradictions in the sustainable development of today's society. In order to meet the requirements of environmental protection and energy saving, the development of low-VOC environmentally friendly water-based coatings has become an inevitable trend in the development of the coatings industry.
