Composite insulation template

Abstract

The application provides a composite thermal-insulation template comprising a thermal-insulation board and a slag mortar layer covering one side of the thermal-insulation board. The slag mortar layer is formed by coarse slag, slag powder, cement, and a water reducer; and the particle diameter of the slag powder is less than 2.5 millimeters and the particle diameter of the coarse slag is 2.5 millimeter to 5 millimeters. According to the invention, with the slag mortar layer, the mass of the template is light and the strength is high. The reinforced concrete material can be saved for the building structure design; and a defect of low strength of a main body board made of an organic thermal-insulation material can be overcome, and deformation can be avoided. high and heavy decoration panels like tiles and marbles and the like can be pasted at the outer side. In addition, because of the slag mortar layer, the heat storage coefficient of the template is increased, so that the thermal inertia index is also improved. Besides, the solid wasted slag is also used by the template, so that the energy is saved, the cost is low, and environment protection can be realized.

Description

technical field [0001] The invention relates to the field of building materials, in particular to thermal insulation templates for buildings. Background technique [0002] At present, according to the country's energy-saving and emission-reduction policies, it is necessary to attach thermal insulation formwork around the concrete components of buildings to reduce heat conduction. Most of the thermal insulation templates of buildings use organic thermal insulation materials, such as XPS extruded polystyrene board and EPS molded polystyrene board, which have good thermal insulation performance and low thermal conductivity. The disadvantage is that the fire resistance level is low and it is easy to cause fire accidents. Subsequent documents issued by the Fire Department of the Ministry of Public Security strictly restricted the use of low-grade refractory materials as external wall insulation materials.

Problems solved by technology

Most of the thermal insulation templates of buildings use organic thermal insulation materials, such as XPS extruded polystyrene board and EPS molded polystyrene board, which have good thermal insulation performance and low thermal conductivity. The disadvantage is that the fire resistance level is low, which is easy to cause fire accidents

[0003] Some other insulation materials, such as STP vacuum insulation materials, foamed cement boards, rock wool boards, phenolic boards and other A-class fireproof materials, although they have a high fire resistance rating, their water absorption rate is very high and their mechanical strength is low.

Therefore, after using these materials as insulation materials for concrete components, problems such as cracks and water seepage are prone to occur.

And because of its low mechanical strength, it is easy to deform, so heavy decorations such as tiles and marble cannot be pasted on its surface.

[0004] Some thermal insulation materials are to brush refractory materials on both sides of XPS extruded board and polyurethane board, such as cement mortar. fall off
