Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the packing explosive puncture-resistant structure of composite membrane schematic diagram of the utility model preferred embodiment.
Detailed description of the invention
The packing explosive puncture-resistant structure of composite membrane of the utility model preferred embodiment as shown in Figure 1, comprise upper layer film 1 and lower membrane 3, between upper layer film 1 and lower membrane 3, be provided with the thermoplastic resin puncture-resistant functional layer 2 adopting inorganic filler and thermoplastic resin to be co-extruded; Upper layer film 1 and lower membrane 3 are the skin covering of the surface adopting high density polyethylene (HDPE), LLDPE, Masterbatch hybrid process to be prepared from; The glue that upper layer film 1, lower membrane 3 are made by employing 5 kilograms of polyurethane binder, 1 kilogram of curing agent and 6 kilograms of ethyl acetates with thermoplastic resin puncture-resistant functional layer 2 respectively and upper layer film and lower membrane are bonded together; Thermoplastic resin puncture-resistant functional layer 2 thickness is greater than rete 1 and lower rete 3.Because centre adopts thermoplastic resin puncture-resistant functional layer 2, formula and preparation technology are simply, with low cost, realize packing explosive film and are not punctured under environment for use, are easy to explosive and store, eliminate safe hidden trouble.
Preferably, in above-described embodiment, thermoplastic resin puncture-resistant functional layer 2 thickness is 90-120 micron.Thermoplastic resin puncture-resistant functional layer 2 is made up of thermoplastic resin matrix and inorganic filler, and each component mass percent is thermoplastic resin matrix 75%-90%; Inorganic filler: 10%-25%.Thermoplastic resin matrix can adopt one or more in polyethylene or polypropylene.Inorganic filler can adopt one or both the mixture in talcum powder or mica sheet.The particle diameter of inorganic filler is 20-100nm.Adopt individual layer film extrusion.Described pet resin layer adopts pet resin.
Preferably, in above-described embodiment, upper layer film thickness is 60-90 micron, and lower membrane thickness is 60-90 micron.Upper layer film, lower membrane preparation technology are as follows: raw material (high density polyethylene (HDPE), LLDPE, Masterbatch) is added inflation film manufacturing machine, blown film is out cut afterwards, blowing is out tubular, folds after putting down and carries out cutting into the independent film of two parts, wound into a roll respectively.
Preferably, the adhesive layer thickness between upper layer film 1 and thermoplastic resin puncture-resistant functional layer 2 is 1-3 micron; Adhesive layer thickness between lower membrane 3 and thermoplastic resin puncture-resistant functional layer 2 is 1-3 micron.In adhesive, ethyl acetate is used for glue to dilute, too thickness is unfavorable for coating, cable roll is adopted to apply at the lower surface of upper layer film and the upper surface of lower membrane during coating, spread is 2.5-5g/ ㎡, the upper layer film 1 having applied glue is entered level Four drying tunnel (4 drying tunnel blowing hot-airs) respectively with lower membrane 3, temperature increases gradually from 35-50 degree, this process is mainly in order to drain the ethyl acetate in glue, then compound is carried out, compound tense adopts stainless steel warm-up mill to carry out pressing, temperature is at about 50 degree, film after compound carries out rolling, finally carry out slaking, place 24 hours in the drying room of 40 degree, reach and solidify completely.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
