Preparation process of composite polyurethane color steel insulation board and color steel insulation board
By optimizing the process of phenolic board pretreatment and polyurethane color steel continuous production line, the three-dimensional positioning, sealing spraying and full filling of phenolic board and polyurethane are achieved to form an integrated composite board. This solves the problems of brittleness of phenolic board and flammability of polyurethane, and realizes a composite board with high fire resistance, high heat insulation and high strength, while reducing the scrap rate.

AI Technical Summary
Existing phenolic foam and polyurethane materials in the field of building insulation have the problem of not being able to balance fire safety and mechanical durability. Existing composite processes have defects such as interface delamination, delamination and performance degradation, making it difficult to achieve the synergistic effect of material performance.
A composite polyurethane color steel insulation board manufacturing process is adopted. Through the pretreatment of phenolic board and the debugging of polyurethane color steel continuous production line, the three-dimensional positioning and fixing of phenolic board, double-sided vertical sealing spraying and overall full filling foaming of the middle are realized to form an integrated structure of phenolic fireproof core layer and polyurethane all-round covering and reinforcing layer. The high-pressure foaming and chemical bonding of polyurethane are used to achieve one-time molding.
A new type of integrated composite board with high fire resistance, high heat insulation and high strength has been developed. The overall thermal conductivity is reduced, the oxygen index is increased and the compressive strength is improved. It solves the problems of brittleness of phenolic board and flammability of polyurethane, and the scrap rate is reduced to below 2%.
