Abstract
The invention relates to a method for processing a polystyrene foaming section, The polystyrene foaming sectional material is prepared from a main material of a mixture of general polystyrene and impact-resistant polystyrene, auxiliary materials of nanometer beta silicon carbide and nanometer light active calcium carbonate, and an auxiliary agent and a colorant by mixing. The method for processing the polystyrene foaming section comprises the following: step one, mixing the auxiliary agent and the colorant first, and then mixing and stirring the mixture with the main material and the dried auxiliary materials to prepare a mixed material; step two, extruding and forming the mixed material in an extruding machine; and step three, performing surface processing according to set grains, and cutting out the formed material by size to prepare the polystyrene foaming sectional material. Compared with the prior PVC section, the polystyrene foaming sectional material has the following advantages that: a general extrusion process is adopted for forming without special requirements on extruding devices and the like, the processing cost is low, and the polystyrene foaming section is colorfast and has good planarity, water resistance, insect prevention, decay resistance, convenient construction, environmental production, replacement of wood, energy conservation and recycling raw materials.
Description
Technical field
The present invention relates to the machine-shaping of plastic products, especially a kind of processing method of polystyrene foaming section.
Background technology
Wooden profile material is indoor and outdoor furniture, paving or ornamental main material, but the wood grows cycle is long, resource is few, cost of manufacture is high.A lot of products with the composite replacing wood have appearred now on the market.But making the section bar with wooden profile material outward appearance with polystyrene does not spread out on market as yet with the product that replaces solid wood material.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing method of polystyrene foaming section, and technology is simple, the similar solid wood material of the section bar that makes.
The present invention solves the problems of the technologies described above the technical scheme of being taked: a kind of processing method of polystyrene foaming section, mixture with general purpose polystyrene and impact resistant polystyrene is a major ingredient, nano beta carborundum and nanoscale light active calcium carbonate are auxiliary material, and auxiliary agent and colouring agent mix, and processing method comprises the steps:
The first step: auxiliary agent and colouring agent are mixed earlier, mix stirring with major ingredient, dried auxiliary material again, make compound;
Second step: compound is extruded machine-shaping in extruder, adopt general expressing technique;
The 3rd step: carry out Surface Machining by setting lines,, make polystyrene foaming section by the size cutting.
On the such scheme basis, described polystyrene foaming section comprises following component by weight:
General purpose polystyrene 100 weight portions
Impact resistant polystyrene 25～35 weight portions
Nano beta carborundum 1～3 weight portion
Nanoscale light active calcium carbonate 1～3 weight portion
Auxiliary agent 1～3 weight portion
Colouring agent 0.5～2 weight portion.
Concrete, in general purpose polystyrene 100 weight portions,
The consumption of impact resistant polystyrene can be 25,26,27,28,29,30,31,32,33,34 or 35 weight portions;
The consumption of nano beta carborundum can be 1,1.5,2,2.5 or 3 weight portions;
The consumption of nanoscale light active calcium carbonate can be 1,1.5,2,2.5 or 3 weight portions;
The consumption of auxiliary agent can be 1,1.5,2,2.5 or 3 weight portions;
The consumption of colouring agent can be 0.5,1,1.5 or 2 weight portions.
On the basis of such scheme, the polystyrene foaming section that the 3rd step was made carries out an acceptance inspection, the finished product warehouse-in; Waste product carries out color grading, pulverizing, recovery granulation in regular turn, is circulated to auxiliary material, auxiliary agent and colouring agent to mix stirring once more, makes compound.
On the basis of such scheme, described auxiliary agent comprises ultra-violet absorber, the agent of the liquid banksia rose, blowing agent, dispersant and lubricant.Wherein, described blowing agent is CF-420, is white powder, the endothermic blowing agent spontaneous nucleation; On the basis of such scheme, described lubricant comprises the AC6A exterior lubricant, the G72 internal lubricant.
The present invention and PVC section bar ratio, its beneficial effect is: adopt general expressing technique moulding, to no specific (special) requirements such as extrusion equipments, processing cost is low, product is colour-fast, do not chap, not reflex action, planarization is good, not yielding and waterproof, protection against the tide, insect protected, anti-rotten, convenient construction, environmental protection, nontoxic, alternative timber, energy savings, raw material can be recycled sustainable development.

| Colouring agent | ?1 | 0.5 | ?2 |
Processing method comprises the steps:
The first step: auxiliary agent and colouring agent are mixed earlier, mix stirring with major ingredient, dried auxiliary material again, make compound;
Second step: compound is extruded machine-shaping in extruder;
The 3rd step: carry out Surface Machining by setting lines, by the size cutting, for a size cutting not the material of compound specification carry out secondary operations, make polystyrene foaming section;
The 4th step: the polystyrene foaming section that the 3rd step was made carries out an acceptance inspection finished product warehouse-in, quantitative package, shipment; Waste product carries out color grading, pulverizing, recovery granulation in regular turn, is circulated to add in proportion to produce, and mixes stirring once more with auxiliary material, auxiliary agent and colouring agent, makes compound.
