Problems solved by technology

However, this kind of EPS board only melts the flame retardant and polystyrene particles and then makes the particles into foam molding, which greatly reduces the strength and water absorption of the EPS board, and its thermal conductivity is as high as 0.040w / m.k, not conducive to the application of EPS board

Abstract

The invention provides an energy-saving and environment-friendly thermal insulation material and a preparation method thereof. The energy-saving and environment-friendly thermal insulation material comprises the following components in parts by weight: 60 to 80 parts of polystyrene, 2 to 6 parts of nanometer titania, 2 to 4 parts of nano-aluminium hydroxide, 10 to 14 parts of cross-linking agent, 20 to 30 parts of PPF fiber, 15 to 22 parts of mineral waste residue, 10 to 14 parts of epoxy resin, 8 to 16 parts of foaming agent, and 45 to 60 parts of water. The preparation method comprises the steps of uniformly mixing the components, injecting into a mold, extruding in a spacing way, and maintaining for 8 to 12h under sustained pressure. The thermal insulation material has a higher flame retardant property, a lower heat conductivity coefficient and higher breaking strength.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an energy-saving and environment-friendly thermal insulation material and a preparation method thereof. Background technique [0002] External wall thermal insulation system consists of thermal insulation layer, protective layer and fixing materials (adhesives, anchors, etc.) External wall insulation can reduce the impact of cold bridges, and at the same time protect the main wall material from large temperature denaturation stress, which has made a huge contribution to building energy saving. It is currently the most widely used energy-saving technical measure in building wall energy-saving in my country , It is also the heat preservation practice vigorously advocated by the state. [0003] At present, there are mainly the following types of external thermal insulation systems used in my country: expanded polystyrene board (EPS) thin plaster external therm...
