Embodiment 1

[0066] In this example, the water paint was prepared according to the following method:

[0067] 1. Raw materials

[0068] The dispersion of 65 parts by weight, the full methyl etherified amino resin of 10 parts by weight (purchased from Cytec), the dimethylethanolamine of 0.2 parts by weight, the defoamer (Tego-902w of Tego Company of Tego Company) of 0.2 parts by weight; The BYK-024 of BYK company, mass ratio is 1:1), the deionized water of 15 weight parts, the substrate wetting and leveling agent of 0.2 weight part (Tego-4100 of Tego company; And the BYK-346 of BYK company, The mass ratio is 1:1), 0.5 parts by weight of surface leveling agent (PW336 of Xianchuang Company), and 0.2 parts of thickener (OMG0620 of OMG Company).

[0069] 2. Steps

[0070] (1) 25 parts by weight of E-20 epoxy resin and 15 parts by weight of E-12 epoxy resin, 3 parts by weight of polyethylene glycol 4000, 2 parts by weight of polyethylene glycol 6000 are dropped into the reaction vessel, and th...

Embodiment 2

[0075] Prepare water paint according to the method for embodiment 1, difference is that raw material is as follows:

Abstract

The invention provides a water-based paint and a preparation method thereof, and a container and a preparation method thereof. The water-based paint comprises a dispersion which is selected from the group consisting of epoxy resin chain-extended by polyamine and epoxy resin chain-extended by m-phenylenediamine. The water-based paint has at least one of the following advantages: good solvent resistance, boiling water resistance, adhesion and scratch resistance, high hardness and fullness, good gloss, low odor and low VOC content.

Description

technical field [0001] The invention relates to the field of chemical industry. Specifically, the invention relates to a water paint for metal surfaces and a preparation method thereof. Background technique [0002] Coating refers to the general term for a class of liquid or solid materials that can form a solid coating film with protection, decoration or special properties (such as insulation, anti-corrosion, signs, etc.) when applied to the surface of an object, including oil (based) paint, water (based) Lacquer, powder coating. Paint is mainly made of benzene and other organic solvents as diluents to decorate and protect articles. Benzene solvents are toxic and carcinogenic, have high VOC emissions, are flammable and explosive, and pollute the environment. Water-based paint is mainly a paint with water as the diluent. Compared with paint, it has the characteristics of energy saving and environmental protection, non-flammable and non-explosive, ultra-low emission, and lo...
