Composite heat-preservation, fireproof and energy-conservation decorating plate and preparing method thereof

Abstract

The invention discloses a composite heat-preservation, fireproof and energy-conservation decorating plate. A preparing method of the composite heat-preservation, fireproof and energy-conservation decorating plate includes the steps that fly ash, lime powder, calcium silicate, a silicone amide foam stabilizer and aluminum powder suspension liquid which are classified and screened serve as raw materials, the raw materials are weighed in weight ratio and subjected to the stirring technology, the steam-curing technology, the pressure forming technology and the like, and an autoclaved-aerated-concrete-block heat preservation layer is prepared; nano-composite siliceous, lime powder, cement, softwood pulp and an additive which are independently developed serve as raw materials, the raw materials are subjected to the stirring technology, the flow-pulp plate preparing technology, the steam-curing technology, the pressure forming technology and the like, and a calcium silicate plate is prepared and serves as a decorating layer; the composite heat-preservation, fireproof and energy-conservation decorating plate is prepared in the mode that the heat preservation layer and the decorating layer are fixed through high-temperature-resistant waterproof glue, the fireproof temperature is 600 DEG C to 700 DEG C, the heat conductivity coefficient is reduced to be 0.01 W / m.K-0.02 W / m.K, energy sources are effectively saved, the composite heat-preservation, fireproof and energy-conservation decorating plate is simple in production technology, durable in using, low in energy consumption, free of pollution and capable of widely applied to the multiple outer wall engineering fields such as municipal construction, apartments and park scenic spots.

Description

Technical field [0001] The invention belongs to the field of building materials, and relates to a composite thermal insulation and fire-resistant decorative board and a preparation method thereof. Background technique [0002] Insulation decorative materials, also known as integrated insulation and decoration finished panels, are prefabricated panels with external wall insulation functions. The thermal insulation decorative board is composed of a composite of thermal insulation materials and decorative materials, and is used for hanging on the outer wall of a building, and has thermal insulation and decorative functions. Traditionally, decoration materials and thermal insulation materials are produced and installed independently of each other. The installation of facade decoration and thermal insulation materials are all manual operations. The construction personnel and working environment will seriously affect the final quality and consume a lot of manpower and material resource...

AI Technical Summary

Problems solved by technology

The decorative layer of the thermal insulation material is made of organic boards, and the fire resistance level is low, which still poses safety hazards.

At the same time, due to the large difference in thermal expansion coefficient between the insulation layer material and the decorative layer material, the product is prone to cracking and unstable performance.

At present, there are few reports on the preparation of an integrated composite thermal insulation, refractory and energy-saving decorative board with inorganic salts as the main raw materials for both the thermal insulation layer and the decorative layer.
