Abstract

The invention relates to a multifunctional composite sheet material and the production process thereof. The production process comprises the following steps: material preparation, hot mixing, cold mixing, extrusion granulation, extrusion output, lamination, aluminum foil attachment and finishing. The sheet material consists of four layers: aluminum foil, a substrate, fiber glass and polyurethane foam. The production process has the advantages of simple process, low cost and easy construction and maintenance. The product has sound-insulating and heat-insulating effects and good resistance to light radiation and thermal radiation. The multifunctional composite sheet material allows the building to meet the requirements for sound insulation, heat insulation, light radiation resistance and thermal radiation resistance. The multifunctional composite sheet material reflects ultraviolet ray in sunlight, ensures normal temperature difference and normal flow and running of oil and gas in a tube, slows down the light ageing and thermal ageing processes of a pipe network, and prolongs the service life of the equipment. Additionally, the multifunctional composite sheet material can efficiently prevent water-freezing and explosion of a pipe and substantially eliminate the noise during water drainage. The product provides good sound-insulating and heat-insulating effects and good resistanceto light radiation and thermal radiation in refrigerated warehouse in logistical refrigerators and special vehicles and ships.
