A preparation method of XPS-foamed cement composite self-insulating straight wall block

Abstract

The invention discloses a preparation method for an extruded polystyrene (XPS)-foaming cement composite self-thermal-insulation vertical wall building block. According to the preparation method disclosed by the invention, the prepared composite building block comprises two parts, namely an XPS insulation board mould body and foaming cement, wherein the XPS insulation board mould body is prepared by an extrusion moulding method and adopts a cuboid structure, the center of the cuboid structure is a cavity, connection reinforcing ribs are arranged in the cavity, the cavity in an XPS insulation board is filled with the foaming cement, and the foaming cement and the XPS insulation board mould body are solidified and bonded together to be utilized as a sandwich material. The composite self-thermal-insulation building block disclosed by the invention has the advantages that the thermal insulation effect is good, the body weight is light, the compressive strength is high, the strength can be regulated and controlled, the shock resistance is high, the sound insulation performance, the seismic performance, the moisture resistance and the frost resistance are good, the long-term stability is excellent, the flame retardance and fire resistance are good (the fireproofing grade of the utilized XPS is B1 and the fireproofing grade of the utilized foaming cement is A), the production process is simple, the construction and building are convenient, and the comprehensive cost is low; the composite self-thermal-insulation building block is especially suitable for construction of passive houses.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an XPS-foamed cement composite self-insulating straight wall block. Background technique [0002] With the increasing crisis of energy and resources, it is necessary to actively advocate green buildings and strengthen the architectural concept of building energy conservation. Using various wall materials with thermal insulation function can not only save a lot of resources, but also reduce energy consumption and environmental pollution. [0003] In this context, the external wall insulation system has been unprecedentedly developed. However, after the implementation and application in recent years, it was found that the energy-saving method of covering the wall with a jacket did not fundamentally solve the energy-saving problem of the building wall envelope, but also brought many problems such as safety, construction, and cost.
