Description
Technical field
The present invention relates to packaging composite films more particularly to a kind of cleaner packing composite membrane and preparation method thereof.
Background technique
Polyethylene is the simplest macromolecular organic compound of structure, the most widely used high molecular material in the world today it
One.Polyethylene is formed by vinyl polymerization, can be made into various application material.Polyethylene is also the main material of packaging material.
It has the advantage that polyethylene resists a variety of organic solvents, resists a variety of acid and alkali corrosions as packaging material, but not inoxidizability
Acid, such as nitric acid；Crystallization material, moisture absorption is small, is not necessary to abundant drying.But there is also some disadvantages, shrinks range and shrinkage value is big, side
Tropism is obvious, easily-deformable warpage.
Polyethylene can be divided into high density polyethylene (HDPE), medium density polyethylene and low density polyethylene (LDPE) according to the difference of density.Its
In, high density polyethylene (HDPE) has rigidity, hardness and mechanical strength big, and low-temperature impact resistance is good, and anti-stress cracking is good, wear-resisting
Good, the ageing-resistant characteristic of property.High-density polyethylene resin is cheap, processing performance is excellent, and physics and chemical property are all good, together
When there is good barrier property to water isopolarity solvent, therefore be widely used in packaging material.
As the exploitation of the continuous improvement that people require commodity packaging, new package material is also more and more important, packing
Film field, it is also higher and higher to film strength and Functional Requirement.In the market for removing the detergent of the stains such as heavy oil
With certain corrosivity and permeability, generally installed using rigid containers.Rigid containers are at high cost, waste society provides
Source, flexible package is at low cost, but corrosion resistance is not achieved.This functional membrane is produced using special material and technique, breaches this
One problem realizes the softening of cleaner packing, reduces entreprise cost, reduces social resources waste.

The mixture of HDPE, LLDPE and MPE (metallocene PE).Wherein, TIE is binder resin, is available commercially, such as Tao Shi, Du
There are production and sales in nation, three Jing Deng companies.
Further, in the material of first adhesive layer, the second adhesive layer and third adhesive layer TIE and PE mass ratio
It is 1: 2.
Further, the mass ratio of HDPE and LLDPE is 1: 3 in the material of the first base material layer and the second substrate layer.
Further, the mass ratio of HDPE, LLDPE and MPE are 1: 2: 3 in the material of the third substrate layer；Described
The mass ratio of HDPE, LLDPE and MPE are 1: 2: 4 in the material of four substrate layers.
A kind of preparation method of above-mentioned composite membrane comprising following steps: (1) 2- for being 2-3% with mass concentration by PA
The methanol solution of hydroxyl -4- methoxy benzophenone impregnates 5-10 hours, then 12-18 hours dry in 60-80 DEG C, spare；
(2) it will be impregnated 8-25 hours in the methanol solution of the MPE silicon fluoride for being 2-3% with mass concentration, then it is dry in 50-100 DEG C
It is 1-5 hours dry, it is spare；(3) it by each layer raw material ingredient in proportion, is separately added into each layer extruder and carries out fusion plastification, squeezes out, so
It is afterwards 1: 1.5-2 in blow-up ratio, die head temperature carries out coextrusion film blowing under conditions of being 220-230 DEG C, and composite membrane is made.
Further, the temperature of each layer extruder is respectively as follows: the first nylon layer and the plasticization temperature of the second nylon layer is
120-180 DEG C, the plasticization temperature of the first adhesive layer, the second adhesive layer and third adhesive layer is 150-200 DEG C, first base material layer and
The plasticization temperature of second substrate layer is 160-180 DEG C, and the plasticization temperature of third substrate layer and the 4th substrate layer is 190-210 DEG C.
In addition, humidity just may be used in such a situa-tion 30 or more for must be at 25 DEG C or more in room when producing this product
To process this product.
The beneficial effects of adopting the technical scheme are that
1, the composite material that method provided by the invention is prepared has excellent anti-corrosion, prevents blending ageing-resistant performance,
Detergent product is being produced and processed, is transported, not contaminated in storage and use process, corrosion, to improve the quality of product
And the market competitiveness.
2, the present invention by raw material carry out pretreatment and multilayer film it is compound, to the pretreatment of MPE make material prevent
Rotten barrier performance substantially improves, and greatly improves the ageing-resistant performance of material the pretreatment of PA, indices are significantly larger than
