Abstract

A polymer microsphere insulation mortar contains the following raw material by weight: the inorganic binder 15-30, lightweight aggregate 20-50, polymer microsphere 5-30, hollow fiber 0.5-3 and dispersible emulsion powder 8-20 and the method includes: fully mixing the raw material by an adding sequence of inorganic cementitious material, hollow fiber, polymer microsphere, dispersible emulsion powder and lightweight aggregate to obtain a mixture, and then blending the mixture with water to obtain a paste shape. The mortar is commonly characterized in both the thermal resistance material and the heat capacity material with high coefficient of the thermal storage, which greatly stabilizes the temperature of the insulation. The high binding force and the overall strength of the mortar and the wall substantially improve the performance of tensile, crack resistance and anti-fracture. A good barrier layer is formed in the middle of the mortar material through a mutual gradation among cement, lightweight aggregate, hollow fiber and polymer materials according to particle size, thereby reducing the hot and cold bridge in the mortar and further improving the thermal insulation performance.

Description

technical field [0001] The invention relates to a building material for coating interior and exterior walls for architectural decoration, in particular to a polymer microsphere thermal insulation mortar. Background technique [0002] In the field of building thermal insulation and energy saving in recent years, the research on high-efficiency thermal insulation mortar has received extensive attention. The reason is that high-efficiency thermal insulation mortar can greatly improve the effect of building energy conservation. The energy saving of buildings is mainly achieved by maintaining the indoor temperature. So it can be said that to achieve high efficiency and energy saving, the best way is to maintain the indoor temperature for a long time by some means. In order to achieve this goal, in addition to improving the building In addition to the sealing, the thermal insulation performance of the building wall should be improved. The simple thermal resistance wall insulation...
