Abstract

The invention provides an outer-wall insulating material and a preparation method thereof. The outer-wall insulating material comprises the following components in parts by weight: 30-40 parts of polystyrene foam particles, 50-60 parts of Portland cement, 10-15 parts of mineral slag, 4-6 parts of wood fiber, 3-5 parts of sodium carboxymethylcellulose, 0-6 parts of foaming agent and 40-50 parts of water. The preparation method comprises the following steps of: firstly weighing the required Portland cement, mineral slag, wood fiber, sodium carboxymethylcellulose and water according to the proportion of a formula, stirring all the components to be uniform slurry-like substance; adding the foaming agent into a foaming machine for foaming, then injecting foam into Portland cement slurry, and stirring to be uniform; then adding the polystyrene foam particles into the Portland cement slurry in ratio, mixing and stirring to be uniform, casting, forming and then naturally curing. The outer-wall insulating material provided by the invention has the advantages that the combustion performance can meet the standard of an A-level incombustible material, the strength is higher and the heat-conductivity coefficient is low.

Description

technical field [0001] The invention belongs to the technical field of building materials, and particularly relates to an external wall thermal insulation material and a preparation method thereof. Background technique [0002] External wall thermal insulation system consists of thermal insulation layer, protective layer and fixing materials (adhesives, anchors, etc.) and is a general term for non-load-bearing thermal insulation structures installed on the surface of external walls. External thermal insulation of external walls can reduce the impact of cold bridges, and at the same time protect the main wall materials from the stress of temperature denaturation. It is also the thermal insulation practice strongly advocated by the state. [0003] At present, the external thermal insulation systems used in our country mainly have the following forms: expanded polystyrene board (EPS) thin plastered wall external thermal insulation system, large mold built-in (with mesh, no mes...
