Abstract

The invention relates to the field of medical apparatus and instruments, in particular to a composite membrane used for a filter and a preparation method thereof and aims at providing the composite membrane which is used for the filter and capable of achieving industrial automation and guaranteeing the product quality and the preparation method thereof. The composite membrane is composed of a nuclear track membrane and a lining membrane; the nuclear track membrane and the lining membrane are bonded into a whole through a composite processing method, wherein the nuclear track membrane is made of PET, and the thickness of the nuclear track membrane ranges from 0.01 mm to 0.02 mm; the lining membrane is made of PE or PP, and the thickness of the lining membrane ranges from 0.1 mm to 0.15 mm. The composite membrane has the advantages of being simple in structure, reasonable in design, convenient to use and the like.

Description

Composite membrane on filter and preparation method thereof
Technical field
The present invention relates to medical instruments field, especially a kind of composite membrane on filter and preparation method thereof.
Background technology
Recent years, automatic liquid-stopping transfusion apparatus is popularized on a large scale in European and American areas, also progressively obtains popularization now at home.Filter in automatic liquid-stopping transfusion apparatus is divided into two kinds, the fine filter of 0.2 micron to 5 microns, and this filter has the filtration index of 600 square millimeters, has the flow indicator of 5 microns of rejection rates and 1000ML.
Filter is generally made up of upper casing, lower casing, nucleopore membranes and lining form, the thickness of nucleopore membranes is generally at 0.01 ~ 0.02mm, the thickness of lining form is generally at 0.1 ~ 0.15mm, because the Thickness Ratio of nucleopore membranes is thinner, so can only manually nucleopore membranes be assembled on filter one by one, thus there is joint place when installing at twice in inefficiency and shaped piece and have the shortcomings such as gap.
For above problem, be badly in need of us and solve.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and realize industrial automation and the composite membrane on filter ensureing product quality and preparation method thereof.
In order to achieve the above object, a kind of composite membrane on filter designed by the present invention, it is made up of nucleopore membranes and lining form; The processing mode that nucleopore membranes and lining form pass through compound is bonding integral, and wherein, the raw material of nucleopore membranes is PET, and the thickness of nucleopore membranes is 0.01 ~ 0.02mm; The raw material of lining form is PE or PP, and the thickness of lining form is 0.1 ~ 0.15mm.
As preferably, the thickness of nucleopore membranes is that 0.01mm is best.
The preparation method of the composite membrane on filter is: the first step, first carries out hydrophily process to the surface of nucleopore membranes, improves the water absorbing capacity of nucleopore membranes; Second step, is combined into one nucleopore membranes and lining form by hot complex machining process, and in recombination process, the temperature of hot compound is 100 ~ 150 °, and applying pressure is 0.3 ~ 0.5Mpa, and improving constantly along with temperature, apply pressure and progressively reduce.
According to the above, a kind of composite membrane on filter designed by the present invention and preparation method thereof, change original nucleopore membranes and lining form individual layer and be assemblied in mode on housing, nucleopore membranes and lining form are combined into one by the mode of compound, are then directly assembled in housing.Therefore, it has the features such as structure is simple, reasonable in design and easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of composite membrane.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of composite membrane on filter that the present embodiment describes, it is made up of nucleopore membranes 1 and lining form 2; The processing mode that nucleopore membranes 1 and lining form 2 pass through compound is bonding integral, and wherein, the raw material of nucleopore membranes 1 is PET, and the thickness of nucleopore membranes 1 is 0.01mm; The raw material of lining form 2 is PE, and the thickness of lining form 2 is 0.1mm.
The preparation method of the composite membrane on filter is: a step, first carries out hydrophily process to the surface of nucleopore membranes 1, improves the water absorbing capacity of nucleopore membranes 1; Second step, is combined into one nucleopore membranes 1 and lining form 2 by hot complex machining process, and in recombination process, the temperature of hot compound is 150 °, and applying pressure is 0.3Mpa, and improving constantly along with temperature, apply pressure and progressively reduce.
