Description

A kind of anstatic desiccant wrapping paper and preparation method thereof
Technical field
The invention belongs to wrapping paper fields, and in particular to a kind of anstatic desiccant wrapping paper and preparation method thereof.
Background technique
General desiccant pack package material is broadly divided into both at home and abroad: country's ventilation paper (filter paper) class, non-woven fabrics, extrusion coating paper, Reticulate pattern paper.Filter paper can be used for the silica-gel desiccant packaging of small dimension, for packing montmorillonite intensity not enough and easily leaking powder, thoroughly Gas is good；Extrusion coating paper gas permeability is poor, causes rate of moisture absorption slow, is generally not suitable for the damp-prrof packing of electronic product；Non-woven fabrics Existing certain intensity, and have excellent gas permeability, but for packing montmorillonite, be easy leakage powder；Common reticulate pattern paper is ventilative Property it is good, intensity is high, and dust tightness is preferable, and applicability is wide, but is easy to be corroded for fields such as chemical foods, and wears no resistance, easily Desiccant is caused to reveal.The main composition of the saturating paper of state is natural plant fibre, and major defect is that material self-strength is not high, heat Sealing strength is poor；It is polyethylene terephthalate (abbreviation PET) and polypropylene (PP) or poly- second that domestic non-woven fabrics, which mainly forms, Alkene (PE), major defect are that material self-strength is not high, and heat seal strength is poor, and anti-dust ability is poor.
With the fast development of social life economy, people increasingly improve desiccant package material requirements, therefore in drying In the selection of agent packaging material, centainly it is noted that the safety of product.The safety of packaging material is mainly reflected in its anti-tensile Intensity, anti-dust performance, encapsulation performance and antistatic performance.The principle of desiccant is played by absorbing the steam in air Control ambient humidity, it is ensured that product provides important protective effect from the invasion of moisture for Product quality and safety guarantee.And it dries It is exactly not antistatic that a bad phenomenon can be generated after agent moisture absorption again, and in daily life, electrostatic is nearly ubiquitous, connects Touching separation electrification will cause spark discharge, and this spark has very big hidden danger in terms of some transport of materials.Mesh Preceding packaging material on the market is all only to focus on moisture-proof, anticorrosion, anti-dust performance, and there are no the desiccant packs for capableing of antistatic Fill paper.
It would therefore be highly desirable to develop a kind of desiccant packing paper its not only mechanical property, heat seal strength, anti-dust performance are strong, And antistatic performance effect is good.

Preferably, wherein the material of antistatic backing non-woven fabrics is selected from one of ES, PET, PP, PE, OPP and blank sheet of paper or several Kind.
Preferably, in antistatic backing, aluminium forms 250~450 angstroms of stack layer on non-woven fabrics, and the mass fraction of aluminium is 99.9% or more.
A kind of preparation method of anstatic desiccant wrapping paper, comprising the following steps:
(1) non-woven fabrics is vacuumized；
(2) aluminium of 99.9% or more heating quality score is evaporated to chilling on non-woven fabrics and accumulates, formed on non-woven fabrics anti- Electrostatic film obtains antistatic backing；
(3) antistatic backing for obtaining step (2) is as surface layer, and for PE material as middle layer, ES hot-wind nonwoven cloth is bottom Layer obtains anstatic desiccant wrapping paper by primary hot-forming.
Preferably, in step (1), the pumpdown time is 10~30min, until vacuum degree is extracted into 10-5~10-4mba。
Preferably, in step (2), in vacuum, by the aluminium of 99.9% or more mass fraction be heated to 1000 DEG C~ 1500 DEG C, it is allowed to be evaporated to chilling on non-woven fabrics, using liquid nitrogen as refrigerant, the temperature of chilling is -150 DEG C~-90 DEG C, shape At 250 angstroms to 450 angstroms of stack layer.
Preferably, in step (3), primary hot-forming temperature is 90~150 DEG C.
It is as follows the present invention also provides the preparation method of two kinds of anstatic desiccant wrapping papers:
A kind of preparation method of anstatic desiccant wrapping paper, comprising the following steps:
