Abstract

The present invention provides a coating material for mineral wool boards, wherein the coating material is obtained by mixing various components, and per kg of the coating material comprises the following components by weight: 0.48-0.55 kg of calcium carbonate, 0.012-0.019 kg of a pigment, 0.004-0.0065 kg of an alkali, 0.001-0.002 kg of a dispersing agent, 0.04-0.065 kg of a tackifier, 0.008-0.03 kg of a film forming agent, and the balance of water. The present invention further provides a method for preparing the coating material. According to the present invention, when the coating material of the present invention is used for the mineral wool board surface, the good whiteness and the good flatness can be obtained compared with the prior art, and the high appearance performance requirements of people on the mineral wool board can be met.

Description

technical field [0001] The invention relates to a paint, in particular to a paint used for mineral wool boards and a preparation method thereof. Background technique [0002] Mineral wool board is a new type of building material. Because of its excellent sound absorption, heat insulation and fire resistance, it is widely used in the ceiling of buildings at home and abroad. In recent years, as people demand conditions for the living environment With the continuous improvement of the society, the mineral wool board is required to have higher decorative performance. In particular, higher requirements are put forward for the appearance whiteness and flatness of the mineral wool board. [0003] At present, the main method to improve the appearance whiteness and flatness of the mineral wool board is to apply a layer of paint on the surface of the finished mineral wool board, thereby improving the whiteness and smoothness of the appearance of the mineral wool board. However, ther...
