Abstract
A kind of PVC foaming aluminum plastic building mould, being formed by upper aluminium alloy plate top layer, lower aluminium alloy plate top layer and middle foamed core layer, do are component and the parts by weight of described middle foamed core layer: SG-5 type polyvinyl chloride resin 25～30,20～50 order PVC waste material powder 60,1000 order precipitated calcium carbonates 10～15, AC blowing agent 0.2～0.3, NC blowing agent 0.4～0.5, foaming control agent 4～5, composite thermal stabilizer 2.5～3.0, paraffin 0.4～0.5, OPE 0.2～0.3, Tissuemat E 0.5～0.6, CPE-135A 4～5. The present invention is taking thermoplastic--and polyvinyl chloride or waste vinylene chloride plastic are base material, using precipitated calcium carbonate as filler, add various auxiliary agents and modifier, through bipyramid extruder and foaming mould extrusion modling, tool smooth surface, intensity are large, good toughness, impact resistance are strong, the feature of long service life.
Description
Technical field
The present invention relates to building template, especially a kind of PVC foaming aluminum plastic building mould.
Background technology
Plastic building template is the 4th generation concreting template after plank sheathing, bamboo offset plate, steel form, is jointEnergy environmentally friendly machine, plastic formwork technology also becomes one of 10 new technologies of building industry (2010 editions) that firmly portion of building widelys popularize.In recent years, China's plastic formwork development is very rapid, and the low foaming formwork of hard PVC is the main flow on China's plastic formwork marketProduct, but because the more traditional bamboo and wood glued board of the low foaming formwork intensity of PVC is poor, apply significantly and limited.
Summary of the invention
Object of the present invention is just to provide that a kind of smooth surface, intensity are large, good toughness, impact resistance are strong, long service lifePVC foaming aluminum plastic building mould.
PVC foaming aluminum plastic building mould of the present invention, by upper aluminium alloy plate top layer, lower aluminium alloy plate top layer and middle foamingSandwich layer forms, and component and the parts by weight of described middle foamed core layer are: SG-5 type polyvinyl chloride resin 25～30,20～50 order PVCWaste material powder 60,1000 order precipitated calcium carbonates 10～15, AC blowing agent 0.2～0.3, NC blowing agent 0.4～0.5, foaming are adjustedJoint agent 4～5, composite thermal stabilizer 2.5～3.0, paraffin 0.4～0.5, OPE 0.2～0.3, Tissuemat E0.5～0.6、CPE-135A4～5。
PVC foaming aluminum plastic building mould of the present invention, with thermoplastic--polyvinyl chloride or waste vinylene chloride plasticFor base material, using precipitated calcium carbonate as filler, add various auxiliary agents and modifier, be squeezed into through bipyramid extruder and foaming mouldType, concrete technology flow process as shown in Figure 1, bipyramid extruder, temperature arranges as follows:
PVC foaming aluminum plastic building mould of the present invention, has overcome existing PVC foaming building template intensity low, poor toughnessProblem, provides a kind of brand-new complex method-plastic-aluminum combined, upper and lower surface Al-alloy plate significantly to improve the strong of templateDegree, toughness, meanwhile, also strengthened the impact resistance of template, increases it and reuse number of times.
Main performance index is as following table:
| Project | PVC plastic building template | PVC foaming aluminum plastic building mould | Detection method |
| Vicat softening temperature, DEG C | 65～75 | ﹥100 | GB/T 1633-2000 |
| Hot size distortion rate, % | 0.5～2.0 | 0.05 | GB/T 8814-2004 |
| High low temperature composite straightedge with protractor cun rate of change, % | 0.5～2.0 | 0.02 | GB/T 8814-2004 |
| Hardness, HD | 70～80 | ﹥100 | GB/T 2411-2008 |
| MOR, Mpa | 20～24 | 40 | GB/T 17657-1999 |
| The modulus of elasticity in static bending, Mpa | 1000～1500 | 5000 | GB/T 17657-1999 |
| Reuse number of times | 25 | 50 | —— |
, as seen from the above table, compare the low foaming building template of common PVC, the combination property of PVC foaming aluminum plastic building mouldAll have significantly and promote. The weather resistance of PVC foaming aluminum plastic building mould significantly promotes, and has improved reusing time of templateCount, widened the range of application of template. Template good processability, can follow closely, digs, saws, cut. Template physical and mechanical property excellence, toolHave the features such as lightweight, high-strength, high-ductility, high rigidity, more traditional bamboo and wood glued board has significant advantage. Template service lifeLong, can Reusability more than 50 times, the template after scrapping can also 100% be recycled. Template is environment friendly and pollution-free, formwork effectGood, the concrete surface after the demoulding is smooth, can do clear water metope. Template water-tolerant, water absorption rate is low, after chance water, does not depositIn problems such as expansion, distortion; Template good flame resistance, can reach B1 level fire-retardant.
