As further technical scheme, described panel is arranged in parallel.
Use and have the beneficial effects that produced by technique scheme:
Owing to sandwich material uses waste or used plastics, its production cost is relatively low, and panel adds fire retardant, it is possible to effectively prevent interlayer from inhaling
Receive too much heat, and then make the heat resistance of template and fire protecting performance good, it is possible to meet actual production demand.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, panel；2, interlayer；3, die cavity passage.
Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
As it is shown in figure 1, be the embodiment 1 of the present invention a kind of cavity type plastic formwork:
Including upper and lower two panels being parallel to each other 1 and interlayer 2, interlayer 2 is provided with several die cavities being parallel to each other uniformly
Passage 3, the moulding of die cavity passage 3 can be born bigger external force, be met the requirement of strength of sheet material so that plastic formwork has weight
The features such as amount is light, intensity is high, the coefficient of expansion is little, impact strength is big.
Anti-flammability and toughness in order to make plastic formwork are further enhanced, and panel 1 includes following materials weight proportion:
Polypropylene 92 parts, fire retardant 6 parts, toughener 2 parts.Fire retardant makes panel 1 have good heat-insulating property so that panel 1 is with outer
The heat exchanger effectiveness on boundary is low, it is possible to be prevented effectively from panel 1 and interlayer 2 too much absorb extraneous heat, and then make panel material
Material has good fireproof flame-retardant effect；Toughener is for increasing the toughness of panel material.
Meanwhile, in order to reduce the production cost of plastic formwork, and also to ensure that its serviceability, interlayer 2 include as follows
Materials proportioning: the waste and old plastic grain of polypropylene 74 parts, plastics Pulvis Talci 20 parts, toughener 2 parts, maleic anhydride grafted polyethylene
4 parts.Use waste or used plastics can effectively reduce production cost, and the physical property needed for Production requirement can be met；Plastics are sliding
Stone powder can be effectively improved heat stability and the intensity of sandwich material；Toughener is for increasing the toughness of sandwich material；Maleic anhydride
Grafted polyethylene belongs to grafting species in modification, by the chemical bond between plastics Pulvis Talci and raw material and, it is achieved
Intensity and the combination of toughness, play a very important role to the serviceability improving sandwich material.
In the present embodiment, the source of polypropylene waste or used plastics can be mainly waste and old battery battery case, raw material side
Easy, it is possible to realize the recycling of plastic resource, beneficially environmental protection.
Said structure makes the panel layer of plastic formwork have good intensity and flame retardant effect, and panel has good resistance to
Hot.Summer when, extreme temperatures in construction site, if panel 1 and interlayer 2 heat absorption after temperature save too high,
Will the fire protecting performance of strong influence plastic formwork, reduce the safety used, adding fire retardant in panel material can
Effectively avoid this problem.
