Abstract

The invention discloses integrally hydrophobic calcium silicate heat insulation spray coating and a preparation method thereof. The hydrophobic mechanism of the coating is characterized in that strong chemical affinity between an organosilicone compound and an inorganic silicate material is sued to effectively change the surface characteristic of the silicate material in order to reach the hydrophobic effect. The integral hydrophobicity of the coating is superior, is slightly affected by surrounding environment, and lasts for a long time; and the coating has heat insulation functions, integrates the advantages of various building materials, and also has the advantages of high practical values, stability in material, long service life, energy saving and environmental protection. The preparation method comprises the following steps: 1, waste recovery; 2, raw material pretreatment; 3, calcium silicate synthesis; 4, modification treatment; 5, granulation; 6, hydrophobic treatment; and 7, coating synthesis.

Description

technical field [0001] The invention relates to a paint, in particular to an integral hydrophobic calcium silicate thermal insulation spray paint and a manufacturing method thereof. Background technique [0002] Under the influence of the global financial crisis, the energy issue has become a prominent contradiction. Due to the rapid economic development of our country, the contradiction between energy and environmental protection has become more prominent. Building energy conservation is mainly to reduce energy consumption and reduce environmental pollution. my country is currently the largest construction market in the world, with about 2 billion square meters of new buildings added every year, of which more than 95% are high-energy buildings. If no energy-saving measures are taken, 50% of the country's energy will be consumed in buildings by 2020. It will bring huge losses to the national economy and energy. The government has promulgated special policies in the form of...
