Abstract
The invention discloses a polystyrene foamed sheet with PP coating layers. The foamed sheet comprises a polystyrene core sheet, PP film layers, and adhesive layers. Each external surface of the polystyrene core sheet is coated with a layer of PP film, and an adhesive layer is provided between each PP layer and the polystyrene core sheet. The production method is that: polystyrene particles are extruded and foamed, and the polystyrene core sheet is shaped; the polystyrene core sheet is foamed to a thickness of 5.0mm to 5.5mm; the obtained product is stored and cured for 10 to 15 days; adhesive is applied on the PP films, and the PP films are then coated on the two surfaces of the cured polystyrene core sheet; the obtained product is shaped by heavy-pressing, and is trimmed and packed. The polystyrene foamed sheet provided by the present invention has simple structure and easy production. Compared to prior polystyrene foamed sheets, the polystyrene foamed sheet provided by the present invention has enhanced surface hardness, flexible quality, and superior performance.
Description
Technical field
The present invention relates to technical field of plastic in the show and colour field, and be particularly related to foamed polystyrene board and manufacturing process thereof that a kind of employing PP (polypropylene) does the overlay film layer.
Background technology
Often using the foaming plate aspect building decoration, advertisement displaying sales promotion, culture and arts and the packing, the product that present market is seen mainly is to make by being covered with the PVC film after the foamed polystyrene moulding, and the application technology of PVC film has been tending towards vague generalization.In the building materials field, use composited aluminum and plastic decking, with as antiultraviolet, anti-aging, fire proofing material more.In this field person skilled the making material and the structural behaviour of various foaming plates are being updated, wished to obtain the better composite plate of performance, to satisfy people's demand higher to quality of the life.
As the Chinese patent notification number is the disclosed a kind of plastic-aluminum combined foaming plate of CN201021510Y, comprises two plastic-aluminum flaggies, is provided with a foamed material layer between the two plastic-aluminum flaggies, and foamed material layer is the polypropylene physical foaming material.Because therefore the foamed material layer that adopts directly foaming to produce between the plastic-aluminum flaggy has stronger fastness, and in light weight, consumptive material is few, has good insulation and effect of heat insulation.And the material that physical blowing obtains does not have toxicity, and can the corroding metal material, and toughness greatly improves, and the plastic-aluminum combined foaming plate of this patent disclosure is compared former composited aluminum and plastic decking substantial change and raising on performance.
The Chinese patent notification number is the disclosed PVC co-extrusion foaming of a CN200955239Y decorative panel, and it is the sheet material by little foaming PVC and UPVC reinforced materials coextrusion mold, and sheet material is the double-decker that little foamed bottom layer of PVC and high strength UPVC superficial layer are formed.The surface longitudinal of sheet material offers groove, is provided with protruding line of apsides bar in the groove; Vertically be provided with reinforcement on the bottom surface of sheet material.It integrates the advantage of timber and plastics by the improvement to plate construction, and surperficial resistance power is strong, and pliability is splendid, and the natural characteristic of similar wood is arranged again, can cut, bonding, connects with nail or bolting.
Above-mentioned employing PVC is more and more as the foaming plate pattern of covering material, though this foaming plate light weight, pliability are good, but the shortcoming that is difficult to overcome is arranged also, case hardness as PVC foaming plate is lower, structure is single, functional limitation's property is strong, can not get expansion, so people are seeking the overlay film layer of the more superior material of other performance as the foaming plate.
Summary of the invention
In order to overcome the defective that above-mentioned prior art exists, the invention provides foamed polystyrene board and manufacturing process thereof that a kind of PP of employing does the overlay film layer, adopt PP as covering material, the case hardness of foaming plate is strengthened, quality is more pliable and tougher, overall performance strengthens, and is applicable to indoor decoratings such as family, hotel, office building office.
To achieve these goals, technical scheme of the present invention is as follows:
Adopt PP to do the foamed polystyrene board of overlay film layer, XPS sandwich layer, PP rete, adhesive phase, the outer surface of described XPS sandwich layer cover one deck PP film, are provided with adhesive phase between described PP film and the XPS sandwich layer.
The upper surface of described XPS sandwich layer or lower surface cover one deck PP film, are provided with adhesive phase between described PP film and the XPS sandwich layer.
In the middle of described XPS sandwich layer is positioned at, described PP rete comprises two, these two PP retes place respectively the top of described XPS sandwich layer and below, between described PP rete and the described XPS sandwich layer is described adhesive phase, and this adhesive phase is fixed together described PP rete and XPS sandwich layer.
Described adhesive phase is neutral glue.
Adopt PP to do the foamed polystyrene board manufacturing process of overlay film layer, may further comprise the steps:
(1) granules of polystyrene foam shaping by extrusion foams to thickness 5.0mm-5.5mm, obtains XPS.
(2) XPS that obtains of step (1) was deposited slaking 10-15 days, as the XPS sandwich layer.
(3) adopt neutral glue, with PP film gluing overlay film, surface one side or two overlay films through the XPS after step (2) slaking form foamed polystyrene board.
(4) with after the foamed polystyrene board weight moulding after step (3) processing, the packing of cutting edge forms the foamed polystyrene board product.
The thickness of described PP film is generally 0.08mm-0.16mm, and is thinner.
Adopt dull and stereotyped hydraulic press to be squeezed to smooth in the described step (4).
The thickness of above-mentioned XPS sandwich layer is generally 5.0mm-5.5mm.
Its main feature is, adopt the PP film before replacing PVC film commonly used changed the situation of former single kind PVC film as the covering material of foamed polystyrene board, make the quality of foaming plate more pliable and tougher, overall performance improves, people's selection is also more diversified.
The main material of PP film is a polypropylene, and its material is softer, and that can do is very thin, by modification, adds auxiliary agent, makes its performance as packing, building and ornament materials better, and it is cheaper to compare its price of PVC film, is accepted by masses easily.
The upper surface of described XPS sandwich layer or lower surface cover one deck PP film.The upper surface or the lower surface that can be the XPS sandwich layer according to actual needs have only one side to cover one deck PP film.The present invention adopts polystyrene to make the foaming plate as expanded material, and raw material are granules of polystyrene, and foam shaping by extrusion lamina core is exactly described XPS sandwich layer.
The invention has the beneficial effects as follows, simple in structure, easy to make, to compare former foamed polystyrene board case hardness and strengthen, quality is more pliable and tougher, and performance is more superior.
Description of drawings
Fig. 1 is the surface structure schematic diagram of one embodiment of the invention;
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated: present embodiment is being to implement under the prerequisite with the technical solution of the present invention, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
