Building composite heat preservation board

Abstract

The invention discloses a building composite heat preservation board, and belongs to the field of building heat preservation materials. The building composite heat preservation board comprises a heat preservation layer, waterproof layers and decoration layers. Reinforced ribs are arranged in the heat preservation layer, and the waterproof layers are arranged on the upper side and the lower side of the heat preservation layer; the decoration layers are arranged on the other faces of the waterproof layers; and the reinforced ribs are of a cross-intersected structure in the heat preservation layer. The heat preservation board after being composited can achieve heat preservation and thermal insulation and can prevent a fire from happening, the reinforced ribs are arranged in the heat preservation board after being composited, so that firmness of connection between the heat preservation board and a base layer wall body is ensured, and the waterproof layers are arranged in the heat preservation board after being composited so that water can be prevented from entering the heat preservation layer. The safety is high, the energy-saving effect is good, the service life is long, the manufacturing cost is low, the heat preservation effect is good, corrosion resistance is achieved, and the property is stable.

Description

technical field [0001] The invention relates to a building composite thermal insulation board, in particular to a composite thermal insulation board suitable for structural buildings requiring thermal insulation for walls and roofs of construction projects. Background technique [0002] With the development of energy-saving work, building external thermal insulation technology has been widely used, but at the same time that external thermal insulation technology is widely used, fire accidents also occur frequently. There are many reasons for fires, but the flammability of thermal insulation materials is also an important reason. At present, the insulation boards used in buildings are mostly polystyrene foam boards, extruded polystyrene boards, molded polystyrene boards and polyurethane foams. These thermal insulation materials have excellent thermal insulation performance, but they are combustible materials, which have the risk of causing fire. Once a fire occurs, the therma...

Problems solved by technology

These insulation materials have excellent thermal insulation performance, but they are combustible materials, which have the danger of causing fire. Once a fire occurs, the insulation board will burn rapidly. Hidden dangers, a large amount of toxic smoke will be produced during the fire
