Polystyrene foam particle heat-insulating mortar

Abstract

The invention discloses polyphenylacetylene foam heat-insulating mortar in and out wall of building and preparing method domain. The mass portion of each component as follow: 65-88 gelling material, 2-22 mineral blending material, 0.1-2 thickener, 0.1-0.4 air-entrainer, 1-2.5 thickener, 3-9 polyphenylacetylene particle and 0-6 building sand. This heat-insulating mortar possesses better thermal insulating effect, which can formulate diverse density and performance request heat-insulating mortar based on diverse environmental condition and thermal insulating demand.

Description

technical field [0001] The invention relates to a commercial mortar for thermal insulation systems in construction engineering, in particular to the field of polystyrene foam thermal insulation mortar for building interior and exterior walls and a preparation method thereof. Background technique [0002] At present, the thermal insulation performance of most houses in my country is far lower than that of developed countries. For example, the heat transfer per unit area of ​​walls, roofs, doors and windows is 2-3 times that of developed countries with similar climate conditions. The reason is that for a long time, my country has put too much emphasis on reducing the one-time investment of buildings, and has not made strict regulations on thermal insulation performance indicators. In addition, the quality control of building materials and construction is not strict. , resulting in long-term energy waste. If we continue to build a large number of houses without energy-saving me...
