Zusammenfassung: | The utility model provides a composite board for producing an air conditioner air supply pipe. The composite board comprises an outer panel, a heat preservation layer and an inner layer, wherein the inner layer is prepared from PVC materials through spiral winding and rolling; an aluminum substrate middle layer is adhered to the outer side of the inner layer; after being glued, the outer side of the aluminum substrate middle layer is coated with heat preservation cotton to form the heat preservation layer, and the outer side of the heat preservation layer is coated with a metal net to form a reinforcing layer, is glued and is adhered with a fireproof layer; the outer panel manufactured by using a color steel plate is arranged on the outer side of the fireproof layer; the inner side wall of the inner layer is coated with fireproof coatings. The scheme has the advantages that the composite board is unlikely to deform and age and long in service life and has a good heat preservation effect. |
