Abstract
The utility model relates to an anti-UV multi-layer co-extruded functional polystyrene (PS) foamed profile which is of a layered structure. The PS foamed profile is characterized by sequentially comprising the following layers from inside to outside: a PS foaming layer, a high impact polystyrene (HIPS) covering layer, an ethylene-vinyl acetate copolymer (EVA) bonding layer, an acrylic-styrene-acrylonitrile (ASA) functional layer and an ASA anti-radiation layer. By adding the ASA functional layer, the surface of the PS foamed profile has crystal-clear effect; and the outermost layer is an ASA resin, wherein, acrylic rubber without unsaturated double bonds in the ASA resin structure is adopted to resist degradation, ageing and fading caused by ultraviolet irradiation and can resist decomposition or discoloration caused by high temperature during the oxidation process in air. Therefore, the anti-UV multi-layer co-extruded functional PS foamed profile has the advantages of excellent ageing resistance and weather resistance and layered product appearance.
Description
Technical field
The utility model relates to the multi-layer co-extruded functional polystyrene foaming section of a kind of uvioresistant.
Background technology
Series of advantages such as polystyrene low-foaming material has that light weight, price are low, insect protected, mothproof, moisture-proof, asepsis environment-protecting.Be widely used in places such as photo frame, picture frame, home decoration material.Along with the raising of people's living standard, also more and more diversified to the performance demands of product, can adapt to outdoor high UV-irradiation environment, surface and have transparent effect as the crystal, durable in use, the non-discoloring product of scratch-resistant more and more is subjected to client's favor.
At present, the polystyrene imitating wood section product major part on the market is the double-layer coextrusion product, and its skin-material mostly is the high impact polystyrene material, stamps various patterns from the teeth outwards by technologies such as ink jet printing, hot rolling seals then.Because the high impact polystyrene material is originally as opaque material, typography can't be copied out the transparent effect as the crystal.And the printing ink ultraviolet-resistant capacity of printing is relatively poor, and easy variable color comes off when using out of doors for a long time, so existing manufacturing technique can't be made the product that the surface has transparent effect as the crystal and is fit to outdoor long-time use.Therefore develop the production technology that makes new advances, make the product that meets the requirements of the customers,, have crucial economic worth to satisfy the growing market demand.
Summary of the invention
According to the deficiencies in the prior art, the technical problems to be solved in the utility model is: provide a kind of uvioresistant multi-layer co-extruded functional polystyrene foaming section, its surface has transparent effect as the crystal, and anti-uv-ray is strong, and product appearance has stereovision.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of uvioresistant multi-layer co-extruded functional polystyrene foaming section, have layer structure, it is characterized in that: be followed successively by foamed polystyrene layer, high impact polystyrene cover layer, ethylene-vinyl acetate copolymer tack coat, acrylic acid-styrene-acrylonitrile functional layer, acrylic acid-styrene-acrylonitrile radiation protective layer from inside to outside.
Be provided with ornament in described acrylic acid-styrene-acrylonitrile functional layer.
Use transparent acrylic acid-SAN in described acrylic acid-styrene-acrylonitrile radiation protective layer.
Also can adopt transparent plexiglass to replace acrylic acid-SAN in described acrylic acid-styrene-acrylonitrile functional layer and acrylic acid-styrene-acrylonitrile radiation protective layer.
Wherein ground floor (sandwich layer) polystyrene (PS) foaming layer is the main part that constitutes product; Second layer high impact polystyrene cover layer (HIPS), main effect is to cover various pores and the other defect that the core layer foaming layer produces, and can stamp background color, determines the dominant hue of product; The three-layer ethylene-acetate ethylene copolymer (EVA) tack coat prevents that bonding is not firm between each layer, produces the generation of the phenomenon of layering; The 4th layer of acrylic acid-styrene-acrylonitrile (ASA) functional layer, this layer adopts transparent ASA resin to add the relatively poor colouring agent of thin shade covering power therein and mixes colours, and add the decoration particle (as circle, rhombus, various petal-shaped particle) of the various different shapes of making by high-melting-point ASA or resin and the good other materials of ASA compatibility, this decoration particle is dispersed in the ASA functional layer in the process of extruding, to produce versicolor Aero Glass; Layer 5 acrylic acid-styrene-acrylonitrile radiation protective layer, this layer adopt transparent ASA resin and add the antioxidant of 0.01%-1% and the UV resistant agent of 0.01%-2% with its oxidation resistance of further raising.
The PS expanded material of ground floor through screw diameter be that the single screw extrusion machine of Φ 90 is extruded, second layer HIPS resin adds that screw diameter is that the single screw extrusion machine of Φ 45 is extruded, the 3rd layer of EVA resin adds that screw diameter is that the single screw extrusion machine of Φ 30 is extruded, the 4th layer of ASA resin adds that screw diameter is that the single screw extrusion machine of Φ 45 is extruded, to add screw diameter be that the single screw extrusion machine of Φ 45 is extruded to layer 5 ASA resin.The material that five extruders are extruded imports in the co-extruding mould, and extrusion molding obtains described multi-layer co-extruded functional polystyrene foaming section.
Wherein also can adopt transparent plexiglass (PMMA) to replace acrylic acid-SAN (ASA) in acrylic acid-styrene-acrylonitrile functional layer and acrylic acid-styrene-acrylonitrile radiation protective layer.
The beneficial effects of the utility model are: by the interpolation of ASA functional layer, the surface has transparent effect as the crystal; Outermost layer adopts ASA (acrylic acid-styrene-acrylonitrile) resin, the degraded of using the acrylic rubber do not contain unsaturated double-bond can resist the ultraviolet ray irradiation in the ASA resin structure to cause, wear out, fade, simultaneously can resist decomposition or the variable color that the high temperature in the aerial oxidation process causes, have fabulous anti-aging and weather resistance; Product appearance has stereovision.
