Abstract
The invention relates to a preparation method of a mildew-proof vacuum compressed bag. The method comprises steps as follows: 60 kg of basic resin, 35 kg of a mildew preventive and 5 kg of a compatilizer are weighed; the basic resin contains vinyl acetate-vinyl copolymers and low-density polyethylene (LDPE Q281 Shanghai Petrochemical) which are equal in weight; on the basis of the total weight of the vinyl acetate-vinyl copolymers, the content of vinyl acetate in the vinyl acetate-vinyl copolymers is 20% by weight; the compatilizer is di(butylcarbitol) adipate and is put in a high-speed stirrer to be mixed uniformly, a double-screw extruder is used for extrusion granulation, a blended material is obtained, 30 granules of the material are weighed and put in a 1 mm-thick mold frame, preheated on a mold pressing machine with the loading and unloading temperature being 180 DEG C for 6 min, then subjected to hot pressing under the pressure of 5.0 MPa for 4 min and subjected to cold pressing under the pressure of 10.0 MPa to the normal temperature, and the mildew-proof vacuum compressed bag is obtained.
Description
Technical field
The present invention relates to Material Field, specifically, the present invention relates to the preparation method of a kind of mildew-resistant vacuum compression bag.
Background technology
The operation principle of vacuum compression plastic bag is that the air within cotton-wadded quilt medicated clothing is taken away so that volume is reduced,
Utilize atmospheric pressure that the article such as the original cotton-wadded quilt expanded are flattened, isolate outside air, to save space, reach dust-proof, mildew-resistant, anti-
Tide, the effect of insect protected.The effect of vacuum compression plastic bag mildew-resistant to be reached, then requiring must before the article such as storage cotton-wadded quilt
The article such as the cotton-wadded quilt being contained are dried or dry.But, many times, the when that user receiving the article such as cotton-wadded quilt in arrangement,
Can not necessarily ensure that the article such as cotton-wadded quilt are dry, this will cause i.e. using the article such as vacuum compression plastic bag storage cotton-wadded quilt,
But the article such as cotton-wadded quilt are also possible to can be mouldy.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of mildew-resistant vacuum compression bag.
In order to realize the purpose of the present invention, the present invention provides the preparation method of a kind of mildew-resistant vacuum compression bag, the method bag
Including: weigh the base resin of 60 kilograms, the antifungus agent of 35 kilograms and the compatilizer of 5 kilograms, described base resin comprises identical heavy
The vinyl acetate-ethylene copolymer of amount and Low Density Polyethylene (LDPE Q281, oil of SPC), based on described vinyl acetate-second
The gross weight of alkene copolymer, the vinyl acetate content of described vinyl acetate-ethylene copolymer is 20 weight %, and described antifungus agent has
There is a having structure:
Described compatilizer is diethylene glycol monobutyl ether adipate ester, puts into mix homogeneously in homogenizer, then uses twin screw
Extruder extruding pelletization, obtains blend composition, weighs 30 pellets and is placed in thick framed of 1mm, at the mould that upper and lower mould temperature is 180 DEG C
First preheat 6min on press, then with the pressure hot pressing 4min of 5.0MPa, then cold pressing to room temperature with the pressure of 10.0MP, to obtain final product.
The present invention also provides for the material with following structural as the purposes in compressed bag antifungus agent:
Mildew-resistant vacuum compression bag of the present invention has good anti-mold effect, is worth large-scale promotion to use.
Detailed description of the invention
Below by way of the description of detailed description of the invention, the invention will be further described, but this is not the limit to the present invention
System, those skilled in the art are according to the basic thought of the present invention, and various modifications may be made or improves, but without departing from this
The basic thought of invention, the most within the scope of the present invention.

The gross weight of ethylene-vinyl copolymer, the vinyl acetate content of described vinyl acetate-ethylene copolymer is 20 weight %, described
Antifungus agent has a having structure:
Described compatilizer is diethylene glycol monobutyl ether adipate ester, puts into mix homogeneously in homogenizer, then uses twin screw
Extruder extruding pelletization, obtains blend composition, weighs 30 pellets and is placed in thick framed of 1mm, at the mould that upper and lower mould temperature is 180 DEG C
First preheat 6min on press, then with the pressure hot pressing 4min of 5.0MPa, then cold pressing to room temperature with the pressure of 10.0MP, obtain sample
Product 1.
Embodiment 2
Preparing sample 2 according to the same manner as in Example 1, difference is not use the mildew-resistant with having structure
Agent:
Experimental example
Performance test
(1) hot strength that ASTMD412-1998 (2002) measures；
(2) HG/T 4301-2012 measures fungicidal properties.
Result
The sample of embodiment 1: hot strength is 17.6Mpa, mildew-resistant grade is one-level, occurs without any mildew；
The sample of embodiment 2: hot strength is 11.3Mpa, mildew-resistant grade is three grades, somewhat has mildew to occur.
From the above results, after adding antifungus agent, intensity and fungicidal properties been significantly enhanced, and before addition
Comparing with result after addition, difference has statistical significance (P < 0.05).
Claims (2)
1. a preparation method for mildew-resistant vacuum compression bag, the method includes: weigh the base resin of 60 kilograms, 35 kilograms anti-
