Assembling type vacuum foam wall body and preparation method thereof

Abstract

The invention discloses an assembling type vacuum foam wall body and a preparation method thereof. The wall body comprises a wall surface layer and vacuum balls, wherein a first containing cavity is surrounded by the wall surface layer; the vacuum balls are arranged in a first containing cavity and are in a closest accumulation arrangement way; the first containing cavity is filled with foamed filler which is distributed in a gap between each vacuum ball and the wall surface layer and in a gap between vacuum walls; each vacuum ball comprises an external protection layer, a vacuum diaphragm andfoam, wherein the external protection layer, the vacuum diaphragm and the foam are arranged in sequence from the outside of the ball body to the inner side of the ball body; a second containing cavity is surrounded by the vacuum diaphragm and is filled with foam. The preparation method is used for manufacturing the assembling type vacuum foam wall body. The assembling type vacuum foam wall body provided by the invention not only can perform a relatively good thermal insulation and heat insulation function but also can perform a relatively good sound insulation effect. In addition, the invention can provide a thinner wall body so as to realize a purpose that indoor use space is increased to a maximum degree under a situation that wall body strength is not influenced.

Description

technical field [0001] The invention relates to the technical field of wall preparation, more specifically, the invention relates to an assembled vacuum foam wall and a preparation method thereof. Background technique [0002] At present, the proportion of building energy consumption in the total energy consumption of countries in the world is quite large. For our country, the huge building energy consumption has gradually affected the sustainable development of our country's economy. Building energy conservation is a comprehensive systematic project, which depends on the thermal insulation effect of exterior walls, doors, windows and roofs, and the thermal insulation and energy conservation effect of exterior walls accounts for 50% to 60% of the whole. Therefore, how to effectively improve the thermal insulation performance of the building's exterior wall is the key to determining the overall energy-saving effect of the building. [0003] The traditional thermal insulation...
