Description
Technical field
The present invention relates to field of packaging material, and in particular to a kind of preparation method of environment-friendly modified Pearl wool material
And its application.
Background technology
Packaging material refers to meeting product packaging for manufacturing packing container, packing and decorating, packages printing, packed and transported etc.
Material used in it is required that, it had both included metal, plastics, glass, ceramics, paper, bamboo sheet, wild mushroom class, natural fiber, chemistry fibre
The main packaging material such as dimension, composite material, and include the auxiliary materials such as coating, adhesive, strapping, decoration, printing material.So
And as the industrialized development of society, all trades and professions need the packaging material being related to multifarious, type is various, while right
The demand of corresponding packaging material steeply rises.But while packaging material embodies its value in industrial society, perhaps
More drawbacks also occurs simultaneously, and frequency of use and durability be not high, and gas that is not degradable, being volatilized is harmful to environment, returns
Receipts mechanism lacks or non-recovery is worth etc..Therefore, exploitation is a kind of having the packaging material of better performance and environmental sound just
Seem particularly necessary.Pearl wool foaming material is a kind of novel environmental protection package, packing material.Its advantageous characteristic, increasingly
It is recognized, therefore its use constantly will expand and innovate.Especially in terms of packing with other industrial cut stocks, it is than passing
System uses material performance more preferable, and cost is lower, class higher, beautiful and generous, better.Pearl cotton is passed through by low density polyethylene (LDPE)
Physical blowing generates countless independent air bubble and constitutes, overcome frangible common foamed glue, deformation, restorative difference disadvantage.Pearl
Cotton have water proof is moisture-proof, shockproof, sound insulation, heat preservation, plasticity is good, toughness is strong, reconstituted circularly, environmental protection, crashworthiness power by force etc. it is many
Advantage also has good chemical resistance, is the ideal substitute of conventional packaging material.But current Pearl wool material
Still to be improved on degradation property, to further enhance its feature of environmental protection.
Invention content
In order to solve the above technical problems, the present invention provides a kind of preparation method of environment-friendly modified Pearl wool material and its answers
With, this method be by talcum powder, mica powder grinding refinement, then with low density polyethylene (LDPE), lauric monoglyceride, polyethylene glycol

In, mixer internal temperature is improved to 180~190 DEG C, at such a temperature internal mixing and plasticizing 40~60 minutes, is then added anti-quiet
0.5~1.5 part of electric agent improves mixer internal temperature to 250 DEG C, and secondary internal mixing and plasticizing 20~30 minutes obtains secondary close
It refines product and heats and maintain molten condition；
（4）15~25 parts of isopropyl three (dioctylphyrophosphoric acid acyloxy) titanate esters, 5~9 parts of isooctyl acid glycidol ether is mixed
Conjunction is heated to molten condition, is added into the secondary mixing product for being similarly molten condition, by temperature after being uniformly mixed
It maintains and keeps mixture in the range of molten state, 1~2 part of physical blowing agent is filled with into molten mixture, keep melting mixed
Object is closed fully to foam；
（5）Molten mixture after foaming is injected in extruder while hot, sets extruder temperature as 150 DEG C, screw speed is
80~100 revs/min, extruder pressure is 50 MPa, and modified pearl cotton material is obtained after extruded, cooling, packaging.
Further, the step（1）Middle mixed material is preferably stirred with 200~300 revs/min of rate in a kettle
Mix reaction 25~35 minutes.
Further, the step（2）The microwave frequency of middle microwave treatment be 280~300 MHz, processing time be 15~
25 minutes.
Further, the step（3）In antistatic agent to be selected from cationic antistatic agent, anionic antistatic
Any one in agent and non-ionic antistatic agent.
Further, the step（4）In physical blowing agent it is any one in butane, hexane and carbon dioxide
Kind.
