Fireproof insulation board of outer wall and preparation method of fireproof insulation board

Abstract

The invention discloses a fireproof insulation board of an outer wall.The fireproof insulation board is prepared from 31-34 parts of cement, 32-39 parts of fly ash, 4-7 parts of quartz powder, 2-5 parts of paper pulp, 9-14 parts of inorganic fibers, 4-9 parts of lime, 1-3 parts of a water reducing agent, 1-3 parts of a composite activity activator, 35-85 parts of fly ash, 11-42 parts of vitrified microbeads, 12-35 parts of acrylic acid emulsion, 4-9 parts of a halogen-free phosphorus series, 2-11 parts of glass fibers, 1-6 parts of a defoaming agent and 1-4 parts of a dispersing agent.The outer side of a main structure is wrapped by the fireproof insulation board of the outer wall, therefore, the main structure can be protected, and the life of a building can be prolonged; hot bridges of a building structure can be effectively decreased, the effective space of the building is increased, the wall surface water condensation phenomenon caused by cold bridges and the hot bridges can be eliminated, and the living comfort degree is improved; the physical performances such as sound insulation and heat insulation of other building materials are not influenced; the fireproof insulation board is more beneficial for volatilization of harmful substances in an outer wall heat insulation material.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fire-proof and thermal insulation board for an outer wall and a preparation method thereof. Background technique [0002] Traditional exterior wall materials are generally ceramic tiles, mosaics, glass curtain walls, stone materials, paints, etc. Ceramic tiles, mosaics, and glass curtain walls have good appearance and decoration, but the construction is complicated, the construction period is long, and the cost is high. In addition, ceramic tiles have poor air permeability and the tile itself is heavy. When it is bonded to the wall, it is easy to fall off due to the composition of the adhesive and the influence of the construction environment, and there is a risk of falling and hurting people. Use tiles. As an exterior wall decoration material, paint is simple in decoration and easy to construct, but its durability is not enough. [0003] Energy conservation is an important...

Problems solved by technology

Its shortcomings are: due to manual wet work on site, it is difficult to ensure the thickness, uniformity, and uniformity of the operation surface, and the plastered area is large, and the plastered surface is prone to stress concentration caused by material shrinkage. Form, climatic conditions, system materials, construction technology, construction management and other reasons, the construction quality is difficult to guarantee, and there are many project quality problems, especially the cracks and hollowing problems on the facade of the thermal insulation system are prone to occur, which will affect the appearance at least , serious water seepage, fall off, loss of energy saving effect, shorten the service life of the building
