Special fireproof mortar of plastic extrusion plate

Abstract

The invention relates to special fireproof mortar of a plastic extrusion plate. A fireproof protection layer is formed at the surface of the plastic extrusion plate, can act as the function of isolating oxygen and enables the oxygen not to directly contact with the extrusion molding plate, thereby avoiding the generation of a combustion reaction. The mortar comprises the following components: 20-50% of cement, 20-60% of sand, 2-10% of dispersible emulsion powder, 0-40% of inorganic composite material and 0.5-10% of organic composite material.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fireproof mortar for preventing and reducing fire hazards during storage and construction of extruded boards in building external heat preservation projects. Background technique [0002] Extruded board is a kind of thermal insulation material with excellent performance, which is widely used in external thermal insulation and internal systems of external walls. However, due to its flammable performance, it is very easy to cause fires on complex construction sites. Recently, fire accidents of building exterior wall insulation materials and systems have occurred one after another in China, which have caused extremely serious losses to the country and people's lives and property, and also caused greater social and political impacts, which have aroused widespread concern from all walks of life. [0003] Combustion can only be carried out under certain conditions, that is, the thre...
