Abstract

The invention discloses an inorganic waterproof ageing-resistant coating and a preparation method thereof. The inorganic waterproof aging-resistant coating is prepared from, by weight, 50-60 parts of silicon sol, 8-12 parts of sepiolite, 3-8 parts of mica, 5-8 parts of pigment, 10-18 parts of a filling agent, 0.5-1 part of a thickening agent and 0.2-0.5 part of a defoaming agent. The preparation method comprises the steps that a packing is added into the silicon sol to be soaked for 3 hours, then scattering is performed under the 1500 r/min condition for 10 minutes, the rotating speed is improved to be 3000 r/min, high-speed dispersion is performed for 20 minutes till the fineness is smaller than 50 micrometers, the rotating speed is reduced to be 800 r/min, the defoaming agent, the thickening agent, a pH regulator and a sterilization fungicide are evenly dispersed and then a finished product is obtained. The inorganic waterproof ageing-resistant coating has waterproof and aging-resistance performance, is non-toxic, is environment-friendly, has low device requirements and is suitable for industrial large-scale production, and the preparation method is simple in operation.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to an inorganic waterproof and aging-resistant coating and a preparation method thereof. Background technique [0002] Over the past 30 years of reform and opening up, my country's economy has continued to grow rapidly, and various constructions have achieved world-renowned achievements, but at the same time, it has also paid a huge price for the destruction of resources and the environment. The contradiction between economic society and resources and environment has become increasingly acute. At the same time, the fact that greenhouse gases cause global warming is drawing widespread attention from the international community. It is also an urgent need to further strengthen energy conservation and emission reduction work in response to global climate change. In order to achieve the sustainable development of the global economy, governments of various coun...
