Description
Technical field
The present invention relates to the compound that a kind of biodegradation material is made, more particularly to a kind of biodegradable packaging of energy
Bag.
Background technology
The life that white pollution has given people brings greatly puzzlement, in order to alleviate this problem, can biological drop
The material of solution has brought hope.Biodegradable polymer refers to that can be degraded or digest in vivo, generation
The family macromolecule material that small-molecule substance is absorbed by organisms and excretes.
Biodegradable packaging bag is carried out there is provided various in the prior art, one as disclosed in Chinese patent CN1335807
Biodegradable bag is planted, it is a kind of film and of the biaxial tension of PLA family polymer by a kind of main component
Kind of main component is that the laminated film that is constituted of film of the aliphatic polyester with predetermined structure is heat-sealed conjunctions, thus mainly into
The film for point being a kind of biaxial tension of PLA family polymer will be used as outer layer.But this biodegradable packaging bag is only
It is that can realize that degraded is buried in soil, and can not realizes meeting water degraded.
The content of the invention
The present invention solves the technical problem of a kind of biodegradable packaging bag of energy is provided, can meet what water was decomposed
Biodegradable packaging bag.
Biodegradable food pack in this programme, contains following components：Polyethylene or polypropylene, the life of polyacids anhydride
Thing degradable material and inorganic filler, the polyacids anhydride biodegradation material are polymerized by material of condensing model and hydroxy acid；
The packaging bag surface is coated with purified lipase, and the purified lipase is formulated by the component of following mass fraction：Polyether tetrolses 20
Part, 14 parts of acid anhydrides silicic acid anhydride, Α-positive 15 parts of pentanediol, 2 parts of erythrol.
Using above-mentioned technical proposal, have the following technical effect that：
By the polyacids anhydride biodegradation material for adding, the packaging bag that order is made is met water and is decomposed；Using restriction component
Purified lipase, can remove the harmful aldehyde material in air, and purify air is played a part of to a certain extent；In the bag
Pack is coated with purified lipase on surface, can reduce the aldehyde material that its surface of packaging bag is dissipated.
Further, according to the mass fraction, the polyethylene or polypropylene occupy 30 parts, polyacids anhydride biodegradation material accounts for
5 parts are occupied according to 40 parts, inorganic filler.
Further, the thickness of packaging bag is 0.5 ~ 1.0um.
Further, the inorganic filler is one or both of calcium carbonate, mica mixture.
Further, the inorganic filler is the last additive in manufacturing process.
Further, the thickness of packaging bag is 0.8um.
Specific embodiment
Below by specific embodiment, the present invention is further detailed explanation：
Embodiment one
Biodegradable food pack, contains following components：Polyethylene or polypropylene, polyacids anhydride biodegradation material and
Inorganic filler, the polyacids anhydride biodegradation material is polymerized by material of condensing model and hydroxy acid；Based on its mass fraction
Calculate, the polyethylene or polypropylene account for 30 parts, polyacids anhydride biodegradation material occupy 40 parts, inorganic filler occupy 5 parts.Packaging
The thickness of bag is 0.8um, can save raw material.
Condensing model class biodegradation material is first generated in manufacturing process, polyethylene or polypropylene addition are then carried out into glass
Glass fibrosis；Finally addition inorganic filler is shaped.
The inorganic filler is one or both of calcium carbonate, mica mixture, draws different packaging bags.The bag
Pack surface is coated with purified lipase, and the purified lipase is formulated by the component of following mass fraction：Polyether tetrolses 200g, acid anhydrides
Silicic acid anhydride 140g, Α-positive pentanediol 150g, erythrol 20g.Its preparation process is by polyether tetrolses 200g, acid anhydrides silicic acid anhydride
140g, Α-positive pentanediol 150g, erythrol 20g are put into four-hole boiling flask, then to nitrogen is passed through in flask, are rapidly heated
To 160 to 180 degrees Celsius, after being then incubated half an hour, then to added in flask polyether tetrolses 100g, acid anhydrides silicic acid anhydride 70g,
Α-positive pentanediol 75g, erythrol 10g, to 250 degrees Celsius, insulation is cooled to room to continuous heating again after 15 minutes in 1 hour
Temperature, then discharges the liquid in flask, and it is purified lipase to be prepared to filter out dope.
Purified lipase can certainly be made varnish, be that net urea formaldehyde, wetting dispersing agent, hexamethylene are added in purified lipase
Ketone, then gradually adds butyl acetate under the conditions of the r/min of rotating speed 300 ~ 500, changes it and arrives reasonable viscosity.
With reference to JC/T 1074-2008《Function of purifying indoor air coating material purifying property》Detected.This is sent out
Bright made purified lipase is made varnish and sprays to respectively on 500 mm × 500 mm glass plates with purified lipase, and every piece of quantity for spray is
200 g.In temperature (20 ± 2) DEG C, relative humidity（50±10）Tested after 7 d are dried in % environment, net aldehyde efficacy test result
Shown in following table：
| Net aldehyde efficiency | Net aldehyde persistence | |
| Purified lipase | ≥86% | ≥52% |
| Varnish | ≥76% | ≥91% |
Thus knowable to table, purified lipase is made varnish, persistence can only be improved, and net aldehyde efficiency can be reduced, so for making
The device do not grown with the time, should not carry out net aldehyde using varnish.
Embodiment two
The present embodiment and the difference of embodiment one are the component ratio for changing purified lipase, i.e. the present embodiment purified lipase is by such as
The component of lower mass fraction is formulated：Polyether tetrolses 180g, acid anhydrides silicic acid anhydride 150g, Α-positive pentanediol 160g, erythrol
120g.Preparation method on purified lipase is identical with embodiment one with net aldehyde detection method.For comparative illustration, it is right to increase in addition
Ratio 1, will the component ratio of purified lipase change into：Polyether tetrolses 180g, acid anhydrides silicic acid anhydride 150g, erythrol 120g；Contrast
Example 2, beautiful color the LC200 general-purpose varnishes of Du Pont of Du Pont.
Embodiment two is directly detected with the purified lipase of comparative example 1（Detected again after without being formed into paint）, using right
The varnish of example example 2 is detected that its last testing result is：
Thus table understands that after have changed the component and ratio of purified lipase in embodiment one, net aldehyde persistence does not substantially change, but
It is that net aldehyde efficiency but has substantially reduction, existing varnish does not have net aldehyde effect substantially.
The above is only embodiments of the invention, and the general knowledge such as known concrete structure and characteristic is not made excessively herein in scheme
Description.It should be pointed out that for a person skilled in the art, on the premise of structure of the present invention is not departed from, can also make
The quantity of some deformations and improvement, locating slot and insert sheet for positioning is three.Positioning head is provided with in-line groove or cross bath.
These should also be considered as protection scope of the present invention, these effects and practical applicability for implementing all without the influence present invention.
This application claims protection domain should be defined by the content of its claim, specific embodiment in specification etc. record can
For explaining the content of claim.
