Description
Technical field
The present invention relates to the little foaming co-extrusion method of a kind of polystyrene.Be specifically related to the little foaming co-extrusion of a kind of polystyrene imitated wood material and preparation method thereof.
Background technology
Series of advantages such as the polystyrene imitating wood section has that light weight, price are low, insect protected, mothproof, moisture-proof, asepsis environment-protecting, long service life.Be widely used in places such as photo frame, picture frame, home decoration material.The technology of imitative wood grain mainly contains following several in the imitated wood material manufacturing process of polystyrene at present: use the various decorative patterns of reflex printing on the surface of polystyrene extruded material 1.; 2. make various decorative patterns at the surface lacquer of polystyrene extruded material; 3. coat gypsum on the surface of polystyrene extruded material, spray paint then and make various decorative patterns.Wherein use the technology of reflex printing wood grain complicated, it is higher to consume energy, and need special equipment that paster and material are heated so that printing ink prints on the polystyrene material, and the paster waste is bigger; The wood grain kind that surface lacquer technology is made is less, and lacquer comes off easily; Gypsum coats lacquer spraying technique, though the lacquer difficult drop-off, itself comes off gypsum easily, and service life is shorter.Therefore demand developing a kind of preparation method of polystyrene imitating wood section urgently, to satisfy the demand in market.
Summary of the invention
The objective of the invention is to provides a kind of high efficiency wood grain manufacture craft for the little foaming co-extrusion of polystyrene material shows, to overcome the defective of prior art.The present invention designs a kind of preparation method of polystyrene imitating wood section, it is characterized in that: preparation skin-material and core material, skin-material and core material are put into respectively in auxiliary extruder and the main extruder, in two extruders co-extrusion to a mould, combine together in mould, wherein skin-material is coated on the surface of core material.The skin-material base material be high impact polystyrene and contain with the high impact polystyrene compatibility good, but mobile and dispersed different flow liner look mother, core material is the polystyrene micro-foaming material, and core material and skin-material weight ratio are 85-95%: 5-15%.Being formulated as of skin-material: get 100 parts of high impact polystyrenes, add primary colours Masterbatch 1-5 part and flow liner Masterbatch 1-5 part, use low speed mixer to mix; Being formulated as of core material: get 100 parts of polystyrene, blowing agent 1-5 part, Masterbatch 1-5 part, plasticizer 1-3 part adds high-speed mixer and mixes.The primary colours Masterbatch is better mobile, is uniformly dispersed, and flow liner look mother is and the high impact polystyrene compatibility is good but melt index is lower, and is dispersed relatively poor in high impact polystyrene.The processing temperature that adds the extruder of core material is 130-180 ℃, and screw speed is 10-35rpm, and the extruder processing temperature that adds skin-material is 150-180 ℃, and screw speed is 5-40rpm.The wood-imitating type material surface of coextrusion produces the embossing of stereoeffect or other effect and handles.Preparation principle disclosed in this invention is: utilize the Masterbatch of different substrate materials, make primary colours Masterbatch and flow liner Masterbatch respectively.Wherein the flowability of primary colours Masterbatch and better dispersed is dispersed in process and forms background color in the polystyrene material, and the flow liner look female and the high impact polystyrene compatibility is good, but melt index is lower, and is dispersed relatively poor in high impact polystyrene.In process, can not be dispersed in the polystyrene material, along with extruding of material forms wood grain or other decorative pattern.Different according to primary colours Masterbatch that skin-material added and flow liner Masterbatch color, the difference of component, the difference of the kind of flow liner Masterbatch, the difference of processing technology can be produced the product of multiple different-effect.As various imitative wood grain products, the product of various patterns etc.
