Description

Technical Field

[0001] The invention relates to the technical field of polyurethane materials, and in particular to a high-temperature resistant polyurethane foaming plate. Background Art

[0002] Due to the supply and demand relationship of artificial boards and some disadvantages such as high formaldehyde content, poor moisture resistance, corrosion resistance and poor flame retardancy and thermal insulation, boards with different functions have appeared on the market, such as wood-plastic boards, composite sandwich honeycomb sandwich boards, glass fiber reinforced polyurethane foam boards, etc. Among them, glass fiber reinforced polyurethane foam boards have more advantages than artificial boards and honeycomb sandwich boards in terms of mechanical properties, thermal insulation properties, service life, stability, processability and post-maintenance.

[0003] However, glass fiber is not environmentally friendly, and glass fiber is a homogeneous glass cylinder. The fabric layers of the polyurethane foam board prepared by glass fiber fabric ply are not connected, and it relies on pure polyurethane foam for support. Therefore, the compressive strength and interlayer shear strength of the glass fiber polyurethane foam board are poor.

[0004] Using green and environmentally friendly biomass fibers as reinforcing materials is the future development trend of fiber-reinforced polyurethane foam boards. Natural fibers have the characteristics of high strength and low density. Cellulose is its main component. The hydroxyl groups on the molecules can form chemical cross-links with polyisocyanates in polyurethane to form carbamates, thereby improving the mechanical properties of the board. However, as a purely natural source, natural fibers have uneven texture and many impurities on the surface, which will affect the distribution of pores, resulting in unstable performance of the board after foaming. In addition, since natural fibers are relatively short, they need to be twisted to form continuous yarns and woven into cloth to meet the molding of continuous boards, which makes it extremely difficult to impregnate polyurethane.

[0005] General polyurethane foam boards are made of completely synthetic polyurethane materials, and their strength is difficult to meet the high difficulty requirements in actual production. In addition, the strength, elasticity and high temperature resistance of polyurethane materials need to be further enhanced to expand their application areas. Summary of the invention

[0006] The present invention aims to overcome the deficiencies in the above-mentioned prior art, and its main purpose is to provide a high-temperature resistant polyurethane foam board. The high-temperature resistant polyurethane foam board divides a foam board into three parts, and polyurethane foam boards with different components are composited to form a foam board with excellent performance and structure, which significantly improves the strength, elasticity and high-temperature resistance of the polyurethane foam board.
