Preparation method of exterior wall bonding powder polystyrene granule insulating mortar

Abstract

The invention discloses a preparation method of exterior wall bonding powder polystyrene granule insulating mortar, relates to the preparation of architectural insulating material and needs to provide a preparation method of an architecture exterior wall insulating material. The preparation method has the technical scheme that ordinary portland cement, flyash, white lime, construction gypsum, cellulose ether, rubber powder, starch ether, xylon and polypropylene (pp) fibre are adopted and is characterized in that the ordinary portland cement, the flyash, the white lime, the construction gypsum, the cellulose ether, the rubber powder, the starch ether, the xylon and the pp fibre are mixed to be polystyrene granules by the weight ratio of 650:200:100:50:515:1:3:1 in sequence; during the preparation of the mortar, a mortar mixer is switched on, 35-40 kg of water is poured into the mortar mixer, 25 kg of rubber powder is poured in mortar mixer and is stirred for 3-5 min, 150-200 L of polystyrene granules is poured in the mortar mixer and is stirred continuously for 3 min, the mixture is poured out after being stirred evenly and can be used after the stir, and the mortar has to be used during 4 hours. The invention is used for preparing architecture exterior wall insulating materials.

Description

Technical field: [0001] The invention relates to a preparation method of building exterior wall insulation materials. Background technique [0002] The first dwellings of human beings were some primitive caves, and they only used rocks and mud blocks to do some necessary insulation. Later, human beings began to use wood, bricks and concrete to build houses. The improvement of the external wall insulation system is a great progress for human living conditions. . [0003] The use of external wall insulation can avoid thermal bridges, and will not cause additional heat loss in cold winter, thereby saving heat energy; at the same time, it also solves the problems of moisture, condensation, and even mildew on the inner surface of the external wall caused by thermal bridges . In summer, the external thermal insulation layer can reduce the combined effect of solar radiant heat entry and high outdoor air temperature, thereby reducing the temperature of the inner surface of the out...
