preparation example Construction

[0031] In a specific embodiment, the preparation method of above-mentioned waterborne epoxy paint, its specific steps are:

[0032] Add 10-15 parts of deionized water, 1-2 parts of water-based dispersant, 0.2-0.5 parts of water-based defoamer, 0.1-0.3 parts of water-based wetting agent, 0.1-0.5 parts of water-based bentonite, modified phosphoric acid 3-6 parts of zinc, 6-10 parts of modified aluminum tripolyphosphate, 10-15 parts of titanium dioxide, 0.5-1 part of carbon black, 10-20 parts of precipitated barium sulfate. When the temperature is below 20 microns, add 30 to 50 parts of special water-based epoxy resin, and get the first component after dispersing evenly.

[0033] In another stirred tank, add 60-80 parts of water-based polyamide epoxy curing agent, 1-5 parts of water-based anti-flash rust additive, and 20-40 parts of deionized water to obtain component B.

[0034] During construction, mix components A and B evenly according to the mass ratio of 5 to 10:1, add an ...

Embodiment 1

[0036] The preparation method of the special water-based epoxy paint for urban rail interior decoration of the present embodiment is as follows:

[0037] Add 12 parts of deionized water, 1.5 parts of water-based dispersant, 0.3 parts of water-based defoamer, 0.2 parts of water-based wetting agent, 0.3 parts of water-based bentonite, 5 parts of modified zinc phosphate, and 5 parts of modified three 8 parts of aluminum polyphosphate, 12 parts of titanium dioxide, 0.8 parts of carbon black, and 15 parts of precipitated barium sulfate. After uniform dispersion at high speed, grind the fineness of the sand mill to below 20 microns, then add 40 parts of special water-based epoxy resin, and disperse After homogenization, component A is obtained.

[0038] In another stirred tank, 70 parts of water-based polyamide epoxy curing agent, 3 parts of water-based anti-flash rust additive, and 27 parts of deionized water were sequentially added to obtain component B.

Abstract

The invention discloses a water-based epoxy coating for rail transit interior decoration and a preparation method. The water-based epoxy coating comprises a component A and a component B, wherein thecomponent A comprises the following components in parts by weight: 30-50 parts of bisphenol A epoxy resin prepared by emulsifying a phosphate emulsifier, 10-15 parts of water and other assistants andadditives; and the component B comprises the following components in parts by weight: 60-80 parts of a curing agent, 20-40 parts of water and other assistants. The problem of adhesive force on the surface of the aluminum alloy without sand blasting and polishing can be effectively overcome and the adhesive force level of the common oily epoxy paint is reached or even exceeded,and the coating has the advantages of extremely low VOC content and TVOC content, stable performance and simple preparation and can be widely applied to rail transit interior decoration and related fields.

Description

technical field [0001] The invention belongs to the field of paint preparation, in particular to a water-based epoxy paint suitable for rail transit interior decoration and a preparation method. Background technique [0002] Epoxy coatings are widely used in the field of coatings due to their excellent anti-corrosion effect on metal substrates. In recent years, due to the increasingly stringent requirements of the country on environmental protection and the increasing requirements of users on indoor air quality, At present, the trend of water-based interior coatings in the rail transit field is becoming more and more obvious. Compared with oil-based paints, water-based paints can greatly avoid indoor air pollution of rail transit vehicles due to their extremely low VOC content. [0003] Since the base material of the interior parts is mainly made of aluminum alloy, the shape is different, and some structures are very complicated. Some parts cannot be completely covered when...
