Abstract
The invention discloses a glass fiber mat enhanced polypropylene plate with a decoration surface layer, relating to a glass fiber enhanced thermoplastic composite material. The glass fiber mat enhanced polypropylene plate takes metal plates as an upper surface layer and a lower surface layer and is formed by taking the polypropylene plate enhanced by a glass fiber mat as a core layer. The invention has the advantages of not only utilizing the high intensity of the glass fiber mat enhanced polypropylene plate and also compounding the metal plates with the actions of decoration and obstruction on the surface. The invention preferentially selects an aluminum foil or an aluminum plate layer and can be coated with corresponding membranes on the upper surface layer and the lower surface layer for further enhancing the obstruction action of the metal plates, thereby expanding an application range of the glass fiber mat enhanced polypropylene plate.
Description
Technical field
The present invention relates to a kind of glass fiber reinforced thermoplastics composite, especially relate to the glass mat RPP plate that has architectural surface.
Technical background
The glass mat reinforced polypropylene compound material has that intensity height, impact flexibility are good, light weight, characteristics such as easy to be recycled, has wide application prospects at aspects such as auto parts and components, building template, container wall panels.But because this material is to be matrix with nonpolar polypropylene, the external coating difficulty is bigger, in the application scenario that needs the outer surface application limitation is just arranged; Material surface reveals glass fibre sometimes, influences product appearance.In addition, resin and glass fibre combination interface have micropore, and gas can spread by micropore, make the occasion of glass mat RPP plate in the better gas barrier requirement of needs, use limited as aspects such as refrigerator car boxboards.Make panel with glass mat RPP plate, can occur during polyurathamc betwixt oozing out in the micropore of polyurethane slave plate and influence outward appearance.Therefore, under situation about directly using with sheet material, the range of application that decorative layer or barrier layer will be expanded material is covered on the surface.
Summary of the invention
The present invention is directed to above-mentioned deficiency, a kind of intensity height, light weight are provided, are easy to application, the glass mat RPP plate that has architectural surface of barrier property is arranged again.
Technical scheme of the present invention is: it is to be upper surface layer and undersurface layer with the metallic plate, is that sandwich layer constitutes with glass mat enhanced polypropylene plate.
Described metallic plate is aluminium foil, aluminium sheet, Copper Foil, copper coin.
Described sandwich layer replaces stacked being melted in by three-layer polypropylene film and layer glass fibrofelt and constitutes together.
Metal sheet surface is coated with film.
The invention has the beneficial effects as follows: the high strength of both having utilized the glass mat RPP, again in surface recombination have and decorate and the metallic plate of iris action, the present invention preferentially selects aluminium foil or aluminum layer for use, in order further to improve the iris action of metallic plate, can apply the corresponding film of one deck in upper and lower surface, enlarge the range of application of glass mat RPP plate.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1-upper surface layer, 2-sandwich layer, 3-undersurface layer.
The specific embodiment
With reference to Fig. 1, the present invention is upper surface layer 1 and undersurface layer 3 with the metallic plate, is that sandwich layer 2 constitutes with glass mat enhanced polypropylene plate.Described metallic plate can be aluminium foil, aluminium sheet, Copper Foil, copper coin or other thistle board commonly used, the present invention preferentially selects aluminium foil or the aluminium sheet with good combination property for use, sandwich layer 2 of the present invention replaces stacked being melted in by three-layer polypropylene film and layer glass fibrofelt and constitutes together, the present invention also can be coated with film at metal sheet surface, with its barrier property of further raising.
The present invention's polypropylene screen that 1.2mm is thick is cut into 1m * 1m size, 760g/m
2Fiberglass needled mat also is cut into 1m * 1m size, with one deck polypropylene screen, layer of glass felt, one deck polypropylene screen, layer of glass felt, one deck polypropylene screen totally five stacked putting, be placed on again between the aluminium foil of two-layer identical size (aluminum foil thickness 0.05mm), put into together and on pressurized state, heat 10min on the hot press, change pressurize cooling 3min on the cold press subsequently over to, board-like material is unloaded in release.Obtaining thickness is the glass mat RPP plate of the band aluminium foil architectural surface of 3.9mm, glass fibre mass percent 30～45% in the sandwich layer, polypropylene mass percent 70～55%.After tested, the peel strength of surperficial aluminium foil is 8.4N/cm, and the hot strength of sheet material is 82MPa, bending strength 126MPa, impact strength 56kJ/m
