[0018] Example 1
[0019] A method for preparing composite decorative paper, the method comprising the following steps:
[0020] (1) Preparation of modified impregnation solution: Weigh 20 parts of formaldehyde, 18 parts of melamine, 3 parts of diethylene glycol, 1 part of sodium hydroxide, and 4 parts of water into the reaction kettle according to mass parts. Stir continuously and slowly heat to 60 parts. After ℃, stop heating and keep the temperature for 30 minutes, add 20 parts of soybean gum, when cooled to 40℃, add 2 parts of aldehyde removal agent to the reaction kettle and cool to room temperature for later use;
[0021] (2) Preparation of composite reinforced powder: add ultrafine Al 2 O 3 5 parts of powder, 1 part of ultrafine quartz stone powder, and 0.1 part of pigment powder are placed in a ball mill and mixed thoroughly to obtain a composite reinforced powder; the fineness of the ultrafine quartz powder is 4000 mesh; the Al 2 O 3 The fineness is 2000 mesh; the fineness o...
