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 a polystyrene cement compound thermal insulation material and a preparation method thereof. The polystyrene cement compound thermal insulation material contains the following components in parts by weight: 30-40 parts of polystyrene foam grains, 50-60 parts of magnesium oxychloride cement, 10-15 parts of porous ceramsite, 4-6 parts of wood fibers, 3-5 parts of sodium carboxymethylcellulose, 0-6 parts of foaming agents and 40-50 parts of water. The preparation method comprises the following steps: firstly, weighting the required magnesium oxychloride cement, porous ceramsite, wood fibers, sodium carboxymethylcellulose and water at formula ratio and stirring till forming uniform slurry matter; adding the foaming agents into a foaming machine for foaming; injecting foams into magnesium oxychloride cement paste and stirring uniform; adding polystyrene foam grains into the magnesium oxychloride cement paste at formula ratio, uniformly mixing and stirring, pouring and forming, and then naturally curing. The polystyrene concrete compound thermal insulation material has combustion performance reaching A-level incombustible material standard, higher strength and low heat conductivity coefficient.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a polystyrene cement composite thermal insulation material, a preparation method thereof, and a non-combustible wall thermal insulation material. 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 polystyre...
