Embodiment 1～3

[0034] Use the polystyrene foam particles specified by the factory or use a crusher to crush the waste polystyrene foam so that the particle size is about 2.5mm. According to the mass ratio of the selected components in Table 1, weigh each raw material. Wherein, the mineral admixture used in embodiment 1-3 is respectively 60 purpose limestone powder, 90 purpose slag and 80 purpose double fly powder, cellulose ether is hydroxyethyl methyl cellulose, air-entraining agent is LP- 50, is water-soluble powder, ethylene-vinyl acetate copolymer latex powder is DM117P of Wacker Company, and the average particle diameter of quartz sand is 1.0mm. The fine powder is mixed first, and then mixed with water and polystyrene foam particles to form thermal insulation 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...
