Background technology:
PET strap is that main raw material is through extruding the shaping a kind of polyester packing belt of unilateral stretching with PET, the novel environment friendly wrapping material of most popular alternative steel band, steel wire, heavy PP strap in the world at present, there is plurality of advantages: (1) stretching resistance is strong, stretching resistance as existing steel band, there is again the shock proof ductility of energy, more can guarantee the transportation safety of product; (2) unit elongation is little, and elongation is only 1/6th of polypropylene tape, can keep tightening force for a long time; (3) security is good, and do not have steel band to get rusty pollution by the drawback of bundle object, color light can reflect; (4) economic benefit is good, and the length of 1 ton of PET strap is equivalent to the steel band length of 6 tons of same specifications, and every meter of unit price is lower than steel band by more than 40%, significantly can reduce packing cost.But, also there is the not good defect of ageing-resistant performance in PET, and thermal destruction and photo-oxidative degradation are the main puzzlements that PET is subject to, and causes PET strap easily aging under rugged environment.
The Chinese patent that publication number is CN101348601B, publication date is 2011.02.09, application people is Southeast China University discloses " plastic-steel baling belt Nano-meter SiO_2
2the preparation method of activeness and quietness PET composite material ", adopt melt-blending process to prepare Nano-meter SiO_2
2reinforced PET Composite masterbatch, gas phase SiO
2mass percentage be 25-40%, molten system remains that high speed shear is disperseed, and mixes in the ultrasound environments of 20KHz, also adds coupling agent KH550 or Al120 in molten system, and its consumption is SiO
2the 2.5-4% of consumption, feeds intake blended with PET by a certain percentage for masterbatch, obtains Nano-meter SiO_2
2the PET composite material of activeness and quietness, its Nano-meter SiO_2
2content be 1-3.5%, Nano-meter SiO_2
2particle is uniformly dispersed in PET, crystal property good, reinforced effects is obvious, good with PET consistency, simultaneously again simple to operate, cost is lower.This invention PET master batch and the blended production plastic-steel baling belt of PET, can improve the intensity, toughness etc. of PET preferably.But, there is the not good problem of ageing-resistant performance in this PET composite material equally, easily aging under rugged environment.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of preparation method of PET strap masterbatch, and the strap masterbatch prepared has good ageing-resistant performance, can be applicable to rugged environment.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A preparation method for Novel PET strap masterbatch, comprises the following steps:
(1) fly ash float is washed, add hydrofluoric acid solution and stir 8 minutes, after suction filtration, washing 5 times with water, be placed in baking oven and dry 3 hours, obtain acidifying fly ash float;
