Fig. 1 is a kind of structural representation of the PS sheet materials of surface papery of the present utility model.

Fig. 2 is a kind of the first structural representation of the support layer of the PS sheet materials of surface papery of the present utility model；

Fig. 3 is a kind of second of structural representation of the support layer of the PS sheet materials of surface papery of the present utility model.

Embodiment

It is real below in conjunction with the present embodiment to make the purpose, technical scheme and advantage of the present embodiment embodiment clearer The accompanying drawing in example is applied, the technical scheme in the present embodiment embodiment is clearly and completely described, it is clear that described reality It is the present embodiment part of the embodiment to apply example, rather than whole embodiments.

Fig. 1 be the present embodiment a kind of surface papery PS sheet materials structural representation, the surface papery of the present embodiment Change, there is three-decker, from top to down for be with the superficial layer 1 that fusing point is 180 DEG C to 190 DEG C, with fusing point 200 DEG C extremely 210 DEG C of support layer 2 and the contact layer 3 that there is fusing point to be 180 DEG C to 190 DEG C, described superficial layer 1, support layer 2 and contact layer 3 height ratio is respectively 20%, 60%, 20%, and described superficial layer 1 uses the papery structure of frosted, in superficial layer 1 Surface forms frosting, papery master batch is added in described superficial layer 1, using the mixing of papery master batch, PS, function additive Thing, wherein the papery master batch, PS, the ratio of function additive are respectively 20%, 70%, 10%；Described support layer 2 uses HIPS, SBS, PS mixed structure, wherein described HIPS, SBS and PS ratio are respectively 65%, 5%, 30%, it is described Contact layer 3 uses PS materials.Above-mentioned signified papery structure, refer to that the surface of superficial layer 1 has the texture of frosted, specific knot Structure is prior art, is no longer being repeated herein.

Further, the raw material of the papery master batch include diatomite, calcium carbonate, kaolin, it is bentonitic a kind of or It is a variety of.Diatomite, calcium carbonate, kaolin, bentonite herein is prior art, and its corresponding combination is only physical process, The component formed is also prior art, and here is omitted.

Fig. 2 is a kind of the first structural representation of the support layer 2 of the PS sheet materials of surface papery of the present embodiment；Fig. 3 For a kind of second of structural representation of the support layer 2 of the PS sheet materials of surface papery of the present embodiment.As shown in Figures 2 and 3, The support layer 2 of the present embodiment uses engraved structure, wherein, the engraved structure forms void region by reinforcement.Its In, void region can be rectangle or rhombus.So, in the case where sheet material gross thickness is constant, integral sheet is reduced Weight, convenient use.The width of above-mentioned reinforcement is 1mm to 2mm, and finite support can be provided with this.

In the present embodiment, HIPS is impact resistant polystyrene, and SBS is styrene (styrene)-butadiene (butadiene)-styrene (styrene) block polymer elastomer, PS is polystyrene.Function additive is this area Conventional material, those skilled in the art can be selected as needed.Above-mentioned HIPS, SBS and PS's is this area Known materials, above-mentioned HIPS, SBS and PS combination formed component be prior art, its accordingly combine only be thing Reason process, here is omitted.

Equipment main technologic parameters set as follows：

In the production process of sheet material, reach the papery effect of class frosted by adding self-control master batch in outer surface layer 1, while Support layer 2 and contact layer 3 increase the ratio or the discharging ratio of increase support layer 2 and contact layer 3 of PS material, to keep PS sheet materials Quality, performance it is constant.

Each layer raw material proportioning is as follows：

Raw material is well mixed according to the above ratio, is added in the three-layer co-extruded equipment set by above-mentioned parameter, it is blended The steps such as extrusion, the regulation of hot pressing thickness, cooling and shaping, trimming, winding obtain the papery PS sheet materials with frosted finish effect.

Above content described in this specification is only to the present embodiment example explanation.Belonging to the present embodiment Those skilled in the art can make various modifications or supplement to described specific embodiment or using similar Mode substitutes, without departing from this example demonstrates that book content or surmount scope defined in the claims, all should Belong to the protection domain of the present embodiment.
