Novel environment-friendly and energy-saving wall heat-preservation wallboard prepared from domestic waste and construction technique thereof

Abstract

The invention discloses a novel environment-friendly and energy-saving wall heat-preservation board prepared from domestic waste and a construction technique thereof. According to the construction technique, the domestic waste such as coal ash, slag, waste building garbage, waste rice hulls, waste tire particles and waste fabric short fibers are utilized reasonably and used for the outer wall heat-preservation board. A heat-preservation board body is square, and the heat-preservation board comprises a heat-preservation board base body and a heat-preservation board face layer; the heat-preservation board base body is a board base body (4) containing waste aggregate, and four square two-way dovetail grooves (2) are formed in the inner side of the board base body; and the heat-preservation board face layer comprises an alkali-resistant glass wool cloth thin plastering internal face layer (1), a polyurethane rubber particle lateral face layer (3) and a polyurethane rubber particle externalface layer (5).

Description

technical field [0001] The invention belongs to the technical field of building engineering construction, in particular to a novel green energy-saving wall thermal insulation wall panel prepared from domestic waste and a construction process. Background technique [0002] The current thermal insulation wall adopts organic materials, such as EPS board, XPS board, polyurethane rigid foam, phenolic board and so on. In order to prevent fire and reduce costs, inorganic materials are also used, such as rock wool board, cement perlite insulation mortar, etc. Inorganic materials have good fire resistance, but the water resistance of rock wool board and the heat insulation performance of cement perlite insulation mortar are poor. Under the premise that the country vigorously advocates sustainable development, aiming at the disadvantages of poor wall insulation performance, high cost of insulation materials, complicated process and lack of wide applicability of the walls of rural res...

Problems solved by technology

From the perspective of construction, the current insulation board construction of the external thermal insulation wall adopts the method of pasting cementing materials between planes. After the rainwater is immersed, due to freezing and thawing and other reasons, there are phenomena such as weak paste, not durable, and easy to fall off; in order to strengthen the insulation of the wall The plate is usually reinforced by self-tapping screws, which will cause local thermal bridges and reduce the thermal insulation performance of the wall.
