Lightweight energy-saving paint and its preparation method

[0016] Example 1

[0017] This implementation example provides a light-weight energy-saving coating that can be applied to high-temperature pipelines and its preparation method. The raw materials and mass ratios used are 55 kg of corundum hollow balls, 10 kg of floating beads, 15 kg of bentonite, and mullite fiber 5 kg, 15 kg of water glass binder with a modulus of 2.5, plus 5 kg of sodium fluorosilicate additive. The preparation process of the lightweight energy-saving paint comprises the following steps: (1) mixing water glass and mullite fiber evenly; (2) adding corundum hollow spheres and stirring evenly; (3) adding bentonite and floating beads and mixing evenly; (4) Add sodium fluorosilicate and mix well 0.5 hours before use. The light-weight energy-saving paint in this implementation example should be applied by manual application, and the performance indicators of the prepared light-weight energy-saving paint are shown in Table 1.
