Description
Technical field
The present invention relates to a kind of XPS sheet material formula and the preparation technology thereof with foam structure.
Background technology
Current XPS (polystyrene foamed plastics be called for short XPS) industry is mainly base material taking polystyrene, after adding the auxiliary agent such as whipping agent, nucleator, plastify through forcing machine high temperature, mix, cooling, then extrudes formation sheet material. Use the XPS sheet material of conventional formulation and explained hereafter, epidermis is thicker, bubble hole around epidermis is less, and diameter is about 15 ��m, and bigger in the bubble hole at position, sheet material center, diameter can reach 100 ��m, cell size difference is very big, and the cell size of sheet material is inconsistent, distributes uneven, thus cause ultimate compression strength and dimensional stability poor, reduce the use range of product. Prior art also has the homogeneity using nano-nucleating agent to improve bubble hole, it is to increase quality product, but such complete processing is complicated, and production cost is higher, is not suitable for market batch production.
Summary of the invention
It is an object of the invention to overcome the defect of prior art existence, it is provided that a kind of XPS sheet material formula and preparation technology thereof with foam structure.
The technical scheme realizing the object of the invention is: a kind of XPS sheet material with foam structure, the XPS sheet material with foam structure is mixed by polystyrene, nucleator, processing aid, whipping agent and suds-stabilizing agent, and its each constituent mass ratio is: 100:0.5��2:0.3��4:9��10:2��10.
As optimization, described nucleator is the mass ratio of the mixture of talcum powder and calcium stearate, talcum powder and calcium stearate is 1:0.3��1.
As optimization, described processing aid is any one in glyceryl monostearate, glycerine three (acetoxyl group stearic acid) ester, two diglycol stearates or triethylene glycol dibenzoate.
As optimization, described suds-stabilizing agent is any one in amino dodecane Soxylat A 25-7, stearylamine Soxylat A 25-7, sorbitan monolaurate or polyoxyethylene-sorbitan mono-oleate.
A preparation technology with the XPS sheet material of foam structure, step is as follows:
1) get the raw materials ready: weigh the suitable polystyrene of proportioning, nucleator, processing aid, whipping agent and suds-stabilizing agent;
2) feeding: parallel dual-screw extruding machine is heated and remains between 190��220 DEG C, again polystyrene, nucleator and processing aid are put in parallel dual-screw extruding machine by weight-loss metering feeding system, when the raw material put in parallel dual-screw extruding machine melts, after being melted to certain viscosity, by whipping agent injected system, whipping agent is injected in parallel dual-screw extruding machine, with three ram pumps, suds-stabilizing agent is injected in parallel dual-screw extruding machine, again by the shearing action of parallel dual-screw extruding machine, make the mixing of each component materials, homogenizing;
3) cooling plasticizing: by mixed melt extrusion to hydraulic screen replacing device filter, then melt is injected in single screw extrusion machine cooling, plasticizing, again mix;
4) shaping: being injected in mould by the melt after cooling plasticizing by the static mixer of constant temperature, extrusion moulding sheet material is put in storage.
As optimization, in step (2), before adding suds-stabilizing agent, suds-stabilizing agent need to being heated to molten state in parallel dual-screw extruding machine, Heating temperature is 25��55 DEG C. The suds-stabilizing agent of molten state is convenient injects parallel dual-screw extruding machine, and can well mix with the material of molten state.
The present invention has positive effect: after the present invention with the addition of processing aid and suds-stabilizing agent, by the preparation technology of this case, by raw materials melt, fully mixing homogenizing, the cell size that the XPS board materials production solving routine causes differs, the problem of board dimension stability difference. Using the sheet material cell size of the present invention's production between 80��170 ��m, according to " GB/T8811-2008 rigid foam dimensional stability test method " detection, when less than 70 DEG C, the dimensional stability of sheet material maintains 1.3��1.5%. Present invention reduces production cost, simplify production technique, it is to increase the quality of product, expand the use range of product, the XPS sheet material stability that this case is produced and ultimate compression strength are better, can be applicable to the fields such as railway, building, highway, are suitable for popularity and use.
