Embodiment Construction

[0023] The proportion of raw materials in this embodiment is as follows: epoxy resin: 30 parts; calcium borate: 21 parts; carbon powder: 2.5 parts; polyvinyl alcohol: 0.3 parts; n-butanol: 0.3 parts; Titanium dioxide: 13 parts; water: 30.4 parts.

[0024] The main components of industrial waste calcium borate are boric anhydride and calcium oxide. Boric anhydride, calcium oxide and carbon powder will generate calcium hexaboride and carbon monoxide at high temperature. The synthesis of calcium hexaboride is very sensitive to temperature changes, and the synthesis temperature The range is relatively narrow, and it cannot be synthesized above or below a certain temperature range. After testing, the chemical reaction is the best when the sintering temperature is 1950K and the holding time is 30min.

[0025] Epoxy resin is a kind of polymer material with poor conductivity, and it has almost no shielding effect on electromagnetic waves. The present invention forms a conductive netw...

Abstract

The invention discloses a latex paint with electromagnetic shielding performance, which is characterized in that the formula is as follows: epoxy resin: 29-31 parts; calcium borate: 20-22 parts; carbon powder: 2-3 parts; polyvinyl alcohol: 0.3 n-butanol: 0.3 parts; silane coupling agent: 2.5 parts; nano titanium dioxide: 12-14 parts; water: 30-31 parts. The latex paint prepared by the invention has the advantages of good electromagnetic shielding, low cost and simple process.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an emulsion paint with electromagnetic shielding performance. Background technique [0002] With the rapid development of electronic information technology, electromagnetic wave radiation pollution has become a major public hazard in today's society, and its impact on economic construction, national defense security and social life is becoming more and more serious. Electromagnetic shielding technology is an effective means to deal with electromagnetic radiation pollution. Various electromagnetic shielding materials, especially electromagnetic wave shielding latex paint, have become new materials for electromagnetic environmental pollution protection due to their high cost performance and good applicability. Research and application a hotspot. The commonly used latex paints with electromagnetic shielding properties use metal fillers such as silver and copper. Due to the high co...
