The invention provides an impact-resistant and flame-retardant lining board and a preparation method thereof. The impact-resistant and flame-retardant lining board is prepared by paving multi-layer phenolic resin prepreg, and the outermost layer of the phenolic resin prepreg is paved There is a surface decorative film; the raw materials for the preparation of the phenolic resin prepreg include phenolic resin and reinforcing materials, the reinforcing material is fiber fabric, and the raw materials for the preparation of the phenolic resin include the following components in terms of parts by mass: 0-100 parts of thermoplastic phenolic resin , 0-100 parts of thermosetting phenolic resin, 1-15 parts of flame retardant, 5-100 parts of toughening agent, 0.05-1 part of coupling agent, and 0-20 parts of curing agent; among them, thermoplastic phenolic resin and The thermosetting phenolic resin is not 0 parts at the same time. The impact-resistant, flame-retardant liner and its preparation method, through the improvement of resin formula and prepreg preparation technology, develop a phenolic resin with high toughness, high flame retardancy, low smoke and low toxicity, and cooperate with the liner configuration design , The optimization of composite material forming technology has obtained the composite material liner with impact resistance and high flame retardancy.

The invention provides a method for preparing an impact-resistant film for automatic access control. The polycarbonate film is treated with an alkali reduction method to increase its specific surface area and improve its hygroscopicity, and to construct a nano-microgel coating on the polycarbonate. layer, has hydrophobic and antibacterial properties, and at the same time improves the adhesion to the glass substrate, modifies the carbon nanotubes, improves the dispersion of the carbon nanotubes, and sprays the silanized coating on the glass substrate, obtained by carbonization , improve the adhesion with the polycarbonate film, and then utilize the water-based polyurethane adhesive to laminate and bond the film, and finally spray a layer of hardened coating to improve the impact strength and wear resistance of the film. The invention provides The preparation method of the impact-resistant film has the advantages of simple preparation method, wide source of raw materials and low cost. At the same time, the prepared film has the characteristics of impact resistance, hydrophobicity, antibacterial, high strength and wear resistance, and can avoid glass bursting and improve safety. , is worth promoting.
