Abstract
Technique the present invention relates to a kind of environment-friendlythin thin film absorption hollow out dishware and preparation method thereof, it is characterized in that environment-friendlythin thin film is adsorbed on tableware completely by the effect of Electrostatic Absorption, both the problem of having avoided the existing germ contamination food of tableware in use, solve the cleaning problems after tableware use again, wherein, environment-friendlythin thin film is made for PLA/PBAT mixing materials, PLA contents are 60% in environment-friendlythin thin film, PBAT contents are 40%, film thickness is 0.015mm, it is with good biocompatibility, compost is degraded under field conditions (factors), it ensure that and environment will not be polluted after film is discarded；Hollow out dishware refers to the U.S. tableware of resistance to ware of hollow out crockery, hollow out made of metal tableware, hollow out, hollow out PLA injection tablewares etc., since tableware is hollow out tableware, saves material, reaches the peak use rate of tableware material.Using conventional equipment, technique is simple, and operation is easy, easy to industrialization promotion application.
Description
Technical field
The invention belongs to environment-friendlythin thin film application field, and in particular to environment-friendlythin thin film production method and increase Electrostatic Absorption
The method of power.
Background technology
Environment-friendlythin thin film is a kind of biodegradable PLA/PBAT modified materials.PLA is mainly with corn, wheat, beet
It is raw material etc. amyloid agricultural product, after fermented generation lactic acid, is polymerized, it is degradable under compost；PBAT is derived from
Oil, but it is with good biocompatibility, it is degradable under compost.It is made again through polycondensation and melt spinning.Face increasingly
Serious white pollution problems, China oneself prevented " white pollution " through beginning to take on measure.On December 31st, 2007 promulgates
" plastic limit ", only its situation or more satisfactory in terms of the execution of big supermarket, the use of plastic shopping bag is big
Width is reduced.It is no inherently to solve the problems, such as " white pollution " but it also has significant limitation.Clothes, packaging for foodstuff,
The various fields such as fresh-keeping, disposable product, the use of plastic film are still startling.
On the other hand, plastics are come out by Petroleum refining, and oil is the natural resources of mankind's preciousness, are non-renewable money
Source.Major part plastics are that oil is raw material at present, and petroleum resources total amount is limited, for the long term growth of descendants, seek
Looking for can substitute the biodegradable plastics of hollow out class plastics to be trend of the times.
The development of biodegradable plastic is improvement and the important channel for solving white pollution, and biodegradation material can be in short-term
In by the microorganism decomposition in nature be CO2With war H2O, will not produce pollution.Moreover, biodegradation material raw material sources
In renewable resource, such as corn and soybean, be conducive to the mankind and break away from dependence to petroleum resources.And it is preceding production and application
In biodegradation material, polylactic acid is that the skilful and widest material of industrialized production and application, polylactic acid raw material source are ground in laboratory
Popularity and biodegradability the research to polylactic acid is particularly important.
The content of the invention
The purpose of the present invention is a kind of environment-friendlythin thin film absorption hollow out dishware of Wholly-degradable of application, environment-friendlythin thin film is
PLA, PBAT are made by blending and modifying, and use upward blown film legal system by single screw rod inflation film manufacturing machine by PLA/PBAT modified materials
.PLA contents are that 60%, PBAT contents are 40% wherein in environment-friendlythin thin film, film thickness 0.015mm.Made by heating, pressurizeing
Obtain environment-friendlythin thin film and be bonded hollow out dishware completely, make to increase its electrostatic force without gas residue therebetween, so that it is thin to complete environmental protection
Film adsorbs hollow out dishware；Or hollow out is bonded completely by coating a kind of pasty masses environment-friendlythin thin film on environment-friendlythin thin film surface
Dishware, makes to increase its electrostatic force without gas residue therebetween, so as to complete environment-friendlythin thin film absorption hollow out dishware.
The object of the present invention is achieved like this：
1st, environment-friendlythin thin film modified materials are manufactured：After PLA is mixed with PBAT by the formula of the environment-friendlythin thin film modified materials, in 160-
At a temperature of 180 DEG C, the environment-friendlythin thin film modified materials are obtained through twin-screw extrusion.
2nd, environment-friendlythin thin film is manufactured：By environment-friendlythin thin film modified materials obtained by above-mentioned 1 step, by single screw rod inflation film manufacturing machine using blowing upwards
Environment-friendlythin thin film is made in embrane method.
It is by vacuum special-shaped hot press vacuum using vacuum pressed, heating during the environment-friendlythin thin film the being related to absorption of the present invention
Pressurization, heating are realized；The pasty masses coated during environment-friendlythin thin film absorption of the present invention, using silica gel material.
The progressive effect of the present invention, conventional equipment, technique is simple, and operation is easy, easy to industrial application.
