Abstract

The invention provides a cement gypsum-based straw light-weight wall heat-insulation board and a preparation method thereof, and relates to the technical field of building materials. The cement gypsum-based straw light-weight wall heat-insulation board comprises a low-density cement gypsum-based straw liner panel, glass fiber gridding cloths, high-density cement gypsum-based straw outer panels andcement gypsum protection layers, wherein the glass fiber grinding cloths are glued on the front side and the back side of the gypsum-based straw linear panel; the high-density cement gypsum-based straw outer panels are arranged on the outer layers of the glass fiber gridding cloths; and the cement gypsum protection layers are arranged on the outer sides of the high-density cement gypsum-based straw outer panels. According to the cement gypsum-based straw light-weight wall heat-insulation board and the preparation method thereof provided by the invention, the various layers in the heat-insulation board are mutually combined, mutually reinforced and synergized, so that the heat-insulation board has a small heat transfer coefficient and an excellent heat-insulation performance, keeps higherstrength at the same time, has a good mechanical property, and is suitable for popularization and application in a large range.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cement gypsum-based straw lightweight wall insulation board and a preparation method thereof. Background technique [0002] At present, building energy conservation has become an important component of my country's sustainable energy development. With people's increasing awareness of energy saving and environmental issues, the development of new wall materials has become the development trend of the construction industry. [0003] my country is a large agricultural country with abundant crop straw resources. And as the crop yield increases year by year, the straw yield also presents a trend of increasing year by year. However, the problem of straw disposal has been a hot issue bothering the production and life of the country and individuals for a long time. To study the discarded straw and make it into new building materials has become a topic that many scholars a...
