Barium-titanium organic composite emulsion and application thereof for preparing external thermal insulation finishing mortar

Abstract

The invention provides a barium-titanium organic composite emulsion and application thereof for preparing external thermal insulation finishing mortar. The preparation method comprises the following steps: (1) mixing nanometer titanium powder, water and grafted gelatin with a barium nitrate solution and an ammonium sulphate solution, adding the ammonium sulphate solution into the mixed solution, preserving the heat, adjusting pH, washing precipitate, and adjusting the pH value once again, and collecting barium-titanium mixed crystal; (2) mixing (methyl) acrylic ester, (methyl) styrene and a molecular weight regulator, and mixing the mixture with a reactive emulsifying agent, an evocating agent and water to obtain a mixed solution; (3) mixing the barium-titanium mixed crystal with water, and adding ethyl hydroxyethyl cellulose, polyvinylpyrrolidone and methacryloxymethyl dimethylethoxysilane into the mixture; and (4) making the mixed solution, the reactive emulsifying agent and the evocating agent react with the product of the step (3), adding the mixed solution into the mixture to obtain the barium-titanium organic composite emulsion. The composite emulsion can be used for preparing the ornamental model finishing mortar composition, and the composition has excellent cracking resistance and water resistance after the mortar composition is formed.

Description

technical field [0001] The invention relates to an artistic modeling type external thermal insulation plastering mortar composition for external walls. Background technique [0002] With the continuous development and progress of human society and the continuous economic growth, energy conservation is important to the sustainable development of human beings, and its significance is to be highlighted. People are constantly exploring and have achieved gratifying results. In energy consumption, the proportion of building energy consumption is about 40%. If effective energy-saving measures are taken and new energy-saving building materials are used rationally, it can not only improve people's office and living comfort, but also save energy due to the use of air conditioners. And consume 40% to 50% of electricity, the reduction of energy consumption reduces the waste of non-renewable resources. The external thermal insulation system of the external wall is being paid more and mo...

AI Technical Summary

Problems solved by technology

The external thermal insulation system of the external wall is being paid more and more attention by people. The plaster mortar for external thermal insulation of the external wall is being continuously developed and developed. Now it is developing towards the integration of art and decoration. On the basis of continuous development, human beings New building materials put forward higher and wider requirements. However, due to the limitations of technology and conditions, the plastering mortars currently on the market cannot meet the requirements of artistic modeling exterior wall external thermal insulation plastering mortars. Water resistance and crack resistance cannot meet the requirements of artistic decoration, and protection treatment is required. Not only the cost is high, the construction period is long, but there are also quality and safety hazards
