Styrene foam particle-magnesium oxychloride cement composite heat insulation material and preparation method thereof

Abstract

The invention discloses a polystyrene foam particle-magnesium oxychloride cement composite heat insulation material and a preparation method thereof. The EPS (expanded polystyrene) particle-magnesium oxychloride cement composite heat insulation material is a novel lightweight organic-inorganic composite heat insulation material which is prepared by steps of firstly foaming magnesium oxychloride cement, industrial waste slag, EPS particles, PPF (polypropylene fiber) fiber, a foaming agent and water by using a slurry body of a cementing material of the magnesium oxychloride cement and further mixing with the EPS particles. The EPS particle-magnesium oxychloride cement composite heat insulation material comprises the following components in percentage by weight: 49.81-52.13% of magnesium oxychloride cement, 16.76-17.52% of industrial waste slag, 1.83-5.61% of EPS particles, 0.37-0.81% of PPF fiber, 0-0.21% of foaming agent and 26.89-28.10% of water. The EPS particle-magnesium oxychloride cement composite heat insulation material disclosed by the invention has the prominent features of low price, good heat insulation performance, energy conservation, waste recycling, environmental friendliness and the like.

Description

technical field [0001] The invention relates to a novel lightweight, organic-inorganic composite thermal insulation material prepared by using polystyrene foam (EPS) particles, magnesium oxychloride cement, industrial waste residue and foaming agent. Specifically, it is an organic-inorganic composite thermal insulation material prepared by combining EPS particles with a gelled material matrix obtained by foaming technology. Mainly used in building energy saving, wall insulation and other fields. Background technique [0002] The construction industry is a pillar industry in my country, and building energy consumption accounts for about 1 / 3 of the total energy consumption of the society. With the acceleration of urbanization and the improvement of people's living quality, the total energy consumption of buildings in my country is increasing year by year, and the high energy consumption of buildings intensifies the energy consumption. The crisis has become the weakness of my c...
