Process for manufacturing integral outer wall decorative plate

Abstract

The invention discloses a process for manufacturing an integral outer wall decorative plate. In the process, the integral outer wall decorative plate is processed on the basis of a prefabrication heat insulation core plate, and the process comprises the following steps of: cutting the heat insulation core plate according to the design size to form a stepped assembly port or a reservation installation groove; cutting a mesh sizing rib lining of a closed shell layer according to the physical characteristics of the cut heat insulation core material; enveloping and positioning the mesh sizing rib lining on the outer surface of the heat insulation core plate to form an integral structure; fixing on a fire protection shell by using infrared heating wind; spraying to form a decorative surface layer on an outer surface of the fire protection shell by using a spraying machine; and drying the decorative surface layer by using the infrared heating wind again. The steps are simple, the integral plate manufactured in a factory can meet the national requirement on the outer wall decorative plate in the conveying and construction process, the prices of the raw materials used in the process are low, the production speed can be improved during batch production, and production cost is reduced.

Description

technical field [0001] The invention belongs to a manufacturing process of an integrated external wall three-proof decoration thermal insulation core board, and the process steps of processing the thermal insulation core material to make a waterproof and fireproof shell after prefabricating the thermal insulation core material. Background technique [0002] With the development of society, high-grade, high-rise buildings have become the symbol of the city. The requirements for fire protection, waterproofing and thermal insulation of high-rise buildings have been raised to a prominent position. And higher and higher requirements are also put forward for the decorative surface of the building's exterior wall. The current completion process of building exterior insomnia includes the manufacture of basic materials and the completion of on-site construction in two stages. In the prior art, the boards manufactured in the factory generally only achieve the purpose of heat preserv...

AI Technical Summary

Problems solved by technology

In the prior art, the boards produced in the factory generally only achieve the purpose of heat preservation, and basically do not carry out fire prevention and waterproof treatment. Only simple fire prevention treatment is added during on-site construction. These treatments cannot prevent the fire during the construction process at all, especially The heat-insulating exterior wall decoration base material currently used belongs to the flammable series. It has been widely used due to its light weight and low cost. However, how to solve the problems of fire prevention and waterproofing has always plagued the field, hindering the insulation core. Application of panels in exterior wall decoration

Some solutions in the prior art are to add a fireproof and waterproof layer to form a sandwich structure on the insulation core board, but the effect is not ideal, especially in the long-term thermal expansion and deformation process, due to the different materials and thermal expansion coefficients of the three-layer structure, A long time will inevitably lead to cracks and warping, and the intrusion of moisture cannot be avoided, and even the insulation material will be exposed, which is prone to fire hazards
