Abstract
The invention relates to an uvioresistant multi-layer polystyrene foaming section bar with co-extrusion function, comprising a layer structure. The uvioresistant multi-layer polystyrene foaming section bar with the co-extrusion function is characterized by comprising a polystyrene foam layer, a high impact polystyrene covering layer, an ethylene-vinyl acetate copolymer adhesive layer, a crylic acid-styrene-acrylonitrile (ASA) functional layer, and a crylic ASA radiation-proof layer from inside to outside, wherein the polystyrene foaming layer is shaped by extruding the following materials in parts by weight in a single-screw extruder: 100 parts of polystyrene, 1-5 parts of foaming agent, 1-3 parts of coloring agent and 1-5 parts of oil; the crylic acid-styrene-acrylonitrile radiation-proof layer is shaped by extruding the following materials in parts by weight in a single-screw extruder: 100 parts of crylic acid-styrene-acrylonitrile, 0.01-1 part of antioxygen and 0.01-2 parts of ultraviolet agent. By adding the ASA functional layer and the ASA radition-proof layer, the invention can prevent degradation, ageing and colour fading caused by ultraviolet irradiation as well as decomposition or discoloration caused by high temperature in the oxidation working process, and has the anti-ageing and weather-resist performance.
Description
Technical field
The present invention relates to a kind of uvioresistant multi-layer polystyrene foaming section bar with co-extrusion function.
Background technology
The series of advantages such as the polystyrene low foaming sectional materials has that quality is light, price is low, insect protected, mothproof, moisture-proof, asepsis environment-protecting.Be widely used in the 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 requirement of the performance of product, can adapt to outdoor high UV-irradiation environment, surface and have transparent effect as crystal, durable in use, the non-discoloring product of scratch-resistant more and more is subject to client's favor.
At present, the polystyrene wood-like profile product major part on market is the double-layer coextrusion product, and its skin-material mostly is high impact polystyrene material, then stamps from the teeth outwards various patterns by techniques such as ink jet printing, hot rolling seals.Originally as opaque material, typography can't be copied out the transparent effect as crystal due to high impact polystyrene material.And the printing ink ultraviolet-resistant capacity of printing is relatively poor, and when using out of doors for a long time, easy variable color comes off, and has as crystal transparent effect and is fit to the outdoor long-time product that uses therefore existing production technology can't be made the surface.Therefore develop the production technology that makes new advances, make the product that meets the requirements of the customers, to satisfy the growing market demand, have very important economic worth.
Summary of the invention
Not enough according to prior art, technical problem to be solved by this invention is: a kind of uvioresistant multi-layer polystyrene foaming section bar with co-extrusion function is provided, and its surface has transparent effect as crystal, and anti-uv-ray is strong, and product appearance has stereovision.
The technical solution adopted for the present invention to solve the technical problems is: a kind of uvioresistant multi-layer polystyrene foaming section bar with co-extrusion function is provided, has layer structure, it is characterized in that: be followed successively by from inside to outside 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, wherein:
The foamed polystyrene layer is put into the single screw extrusion machine extrusion molding by following weight portion raw material,
100 parts of polystyrene
Blowing agent 1-5 part
Colouring agent 1-3 part
Grease 1-5 part
Acrylic acid-styrene-acrylonitrile radiation protective layer adds the single screw extrusion machine extrusion molding by following parts by weight raw material,
100 parts of acrylic acid-styrene-acrylonitriles
Antioxidant 0.01-1 part
UV resistant agent 0.01-2 part.
The wherein tectal preparation of high impact polystyrene: the high impact polystyrene covering layer material is put into the single screw extrusion machine extrusion molding.
The preparation of ethylene-vinyl acetate copolymer tack coat: the ethylene-vinyl acetate copolymer bonding layer material is put into the single screw extrusion machine extrusion molding.
The preparation of acrylic acid-styrene-acrylonitrile functional layer: clear acrylic-styrene-acrylonitrile functional layer material is put into the single screw extrusion machine extrusion molding.
Above-mentioned five layers of extrudate are imported in co-extruding mould extrusion molding.
Described polystyrene can use the GPPS virgin material (beautiful PG-22 as strange in Taiwan) on market, or the polystyrene reclaimed materials.
Described high impact polystyrene material can use the existing trade mark such as the HIPS-514 of Shanghai petrochemical industry Co., Ltd of match section production, the HIPS-425 of Korea S bright and beautiful lake petro-chemical corporation etc. on market.
Described blowing agent is one or more in Celogen Az, diisopropyl azodiformate, diethyl azodiformate, dinitrosopentamethlyene tetramine, 4,4 ' OBSH, sodium acid carbonate, ammonium carbonate or ammonium nilrite.Described colouring agent is toner or Masterbatch, and wherein toner is carbon black, iron oxide yellow, ultramarine, titanium dioxide or iron oxide yellow, and Masterbatch is the mixture of high impact polystyrene and toner.
Described grease is one or more in alkane oil, dioctyl phthalate, dibutyl phthalate, dioctyl adipate, di-n-octyl sebacate, epoxidized soybean oil or epoxyoleic acid butyl ester.
Be provided with the decoration point in described acrylic acid-styrene-acrylonitrile functional layer.
