The paper material being prepared in embodiment 1-5 and comparative example 1-4 is tested for the property, penetrability test reference
GB 1037-88 ；Oxygen permeability test reference GB/T1038-2000；Mechanics Performance Testing refers to GB/T 1404.2-2008, surveys
Test result see the table below:
1 permeability test of table:
2 Mechanics Performance Testing of table
By test result it is found that the paper material that the present invention is prepared has good barrier property, and mechanical property is excellent
It is different.In the preparation of paper material of the present invention, the better crystallinity degree of high molecular material, between filler and high molecular polymer can be very
High fusion, so that the moisture barrier property of paper material is good, OTR oxygen transmission rate is low, and its tensile strength can reach 62MPa, resistance to punching
Hit intensity can reach 12.7Kjm-2。
Do not had a significant impact as plasticizer for the performance of material in comparative example 1 using phthalic acid ester, but
Phthalic acid ester harm is larger, and the present invention uses sunflower oil as plasticizer, and ingredient is safer, and from a wealth of sources,
It is cheap.
Application frequency is 3 times in comparative example 2, and the barrier property of paper is poor, and application frequency is very little, and when tabletting cannot make to apply
Layer and body paper surface are preferably merged, so that its barrier property is poor.
The dosage of powdered rice hulls is more in comparative example 3, and when powdered rice hulls dosage is excessive, resin can not wrap up well it, most
Heat pressure coating is set hole occur eventually, thus its barrier property, mechanical property can all decline.
Comparative example 4 has used unmodified phenolic resin, and comprehensive performance declines, and is modified and changes to phenolic resin
Its brittleness has been apt to it, and has made itself and the better adhesion of paper base material, to improves the comprehensive performance of paper material.
