Embodiment 1
[0031] A method for preparing a high thermal insulation and water-resistant polystyrene sandwich panel, comprising the following steps:
[0032] (1) Preparation of colored galvanized steel sheet
[0033] The hot-dip galvanized steel sheet is used as the base material, and its surface is degreased, phosphating, and chromate-treated, and then a layer of organic paint is applied on the surface of the hot-dip galvanized steel sheet by a two-coating and two-baking process to obtain a colored galvanized steel sheet; Wherein, the organic coating is composed of the following components in parts by weight: 20 parts of water-soluble polyacrylic resin, 2 parts of organosilicon sol, 0.3 part of silane coupling agent, 3 parts of titanium dioxide, 0.2 part of defoamer, 25 parts of water;
[0034] (2) Preparation of polystyrene foam board
[0035] A) By weight, 50 parts of expandable polystyrene particles, 1 part of waterproofing agent, 0.5 part of magnesium hydroxide, and 0.1 part of carb...
