Description
Technical field
The present invention relates to the macromolecule composite sheet, particularly a kind of shock resistance package sheet material and preparation method thereof.
Background technology
Rim charge and the waste product of noncrystallineization PETG APET are recyclable, belong to the degradability plastics, its transparency height has good barrier properties for gases, favorable rigidity and extensibility are widely used in the packing of industries such as cosmetics, food, electronics, toy, printing.But the APET resistance to water is relatively poor, and particularly under hot and humid situation, in sea borne process, hydrolysis can take place material, causes the material shock resistance that becomes fragile to reduce, thus the generating material problems of crack.For improving the shock resistance of APET sheet material, flexibilizer is chosen polyolefin elastomer usually, and as POE, SBS, EPDM etc., but this type of flexibilizer can influence the transparency of APET, and needs to add compatilizer usually.PETG is a PET modification by copolymerization thing, and full name is a PETG-1, the 4-cyclohexanedimethanoester ester, it is by terephthalic acid (TPA), ethylene glycol and 1, three kinds of monomers of 4-cyclohexanedimethanol product of ester-interchange method polycondensation, its goods highly transparent, excellent shock resistance.PETG and APET compatibility are good, with the impact strength of APET recombination energy raising APET sheet material, composite sheet transparency height.
Summary of the invention
The invention provides that a kind of compatibility is good, transparency is high, have the polyester composite sheet material of favorable shock resistance.
Shock resistance package sheet material of the present invention is made up of the superficial layer on substrate layer and substrate layer both sides, described substrate layer is made up of noncrystallineization PETG APET, superficial layer is made up of following components in weight percentage: PETG-1,4-cyclohexanedimethanoester ester PETG resin 85% ~ 95%, smooth master batch 0.1% ~ 0.5%, 0.2% ~ 1% antistatic additive, other auxiliary agent 4% ~ 14%.
Above-described antistatic additive is glycerin monostearate or N, two (2-hydroxyethyl) alkylamines of N-or octyl group acid APEO.
Auxiliary agent of the present invention is polyethylene of dispersing agent wax or OPE.
The thickness of substrate layer of the present invention accounts for 85% ~ 93% of sheet thickness, and the thickness of superficial layer accounts for 3.5% ~ 7.5% of sheet thickness respectively.
Another technical problem that the present invention solves provides the preparation method of above-mentioned shock resistance package sheet material: earlier to load weighted PETG-1, it is dry again that 4-cyclohexanedimethanoester ester APET resin carries out pre-crystallization treatment, to load weighted PETG-1,4-cyclohexanedimethanoester ester PETG resin carries out drying to be handled, with smooth master batch, antistatic additive, the auxiliary agent weighing well the back with dry good to PETG-1,4-cyclohexanedimethanoester ester PETG mixed with resin is even, utilize multi-layer co-extruded sheet extruder extrusion sheet, the substrate layer extrusion temperature is 250 ℃ ~ 280 ℃, the superficial layer extrusion temperature is 230 ℃ ~ 250 ℃, die head is extruded after three roll-ins are prolonged, and cuts edge then, the traction rolling makes the shock resistance package sheet material.
Shock resistance complex polyester sheet material component compatibility of the present invention is good, and sheet material does not have lamination, sheet material transparency height, and smooth surface is smooth, and composite sheet has favorable shock resistance.
