Abstract
The method for making shielding fabric resisting electromagnetic wave radiation includes the steps of coarsing, sensitizing and activating, strengthening, first chemical plating, secondary chemical plating, coating organic layer and drying, and is characterized by that in the sensitizing and activating stage the stannous chloride and silver nitrate solution concentration can be raised, in the strengthening stage the concentration of formaldehyde can be increased, and when the first chemical copper-plating process is implemented, the concentration of cupric sulfate, potassium-sodium tartrate and elhylene diamine tetraacetic acid can be raised, so that it can effectively raise productino speed and product performance. Said fabric also possesses the good performance in wear, permeability and washing property.
Description
The present invention relates to anti-electromagnetic wave radiation shielding fabric, particularly a kind of preparation method of anti-electromagnetic wave radiation shielding fabric.
The non-metallic fibers fabric face obtains conducting metal by chemical method, make its have the electromagnetic radiation resistant ability do not change again fabric itself soft wear characteristic, thereby be widely used in communicating by letter, clothes and Environmental Safety fields such as decoration, shielding that aviation, military affairs etc. need industries such as electromagnetic radiation resistant.
Pay close attention to widely because the excellent specific property of anti-electromagnetic wave radiation shielding fabric has caused both at home and abroad, its manufacture method has also been applied for patent, and the manufacture method of this anti-electromagnetic wave radiation shielding fabric comprises the following steps: substantially
1. host material fabric alligatoring;
2. sensitization activation improves fiber top layer molecule and replaceable slaine and produces the ions binding ability;
3. strengthen the surface structure of reinforcing fiber;
4. chemical plating for the first time, the metal lining conductive layer;
5. chemical plating for the second time, plating has the coat of metal of frequency selectivity;
6. armor coated.
But its technology is desirable not enough, and particularly, promptly activation effect is strong not enough, and amount of deposited silver is insufficient, and chemical plating speed is also fast inadequately.
The objective of the invention is to further overcome the deficiency of prior art, provide a kind of anti-electromagnetic wave radiation shielding fabric improved preparation method, adjust chemical formulation and strengthen activation effect, improve manufacturing speed and its wash durability.
The preparation method of anti-electromagnetic wave radiation shielding fabric of the present invention comprises the following steps:
1. matrix fiber fabric alligatoring strengthens its adhesive force;
2. sensitization and activation makes fabric fibre and transition metal good combination, for road, back metal lining conductive layer lays the first stone;
3. strengthen, make activation further perfect, reinforced fiber fiber surface structure;
4. chemical plating for the first time, it is strong to form conductive capability, the copper layer that radiation resistance is good;
5. chemical plating for the second time forms and has anti-CF electromagnetic radiation nickel coating;
6. be coated with organic coating, strengthen that it anti-is washed, anti-oxidation performance,
Be characterized in
Employing concentration is that the sodium hydroxide solution of 5 grams per liters is removed fabric face dirt and alligatoring fiber;
At the sensitization activation stage, improve the content of stannous chloride and silver nitrate, to strengthen its activation effect, improve the argent deposition;
At strain, the concentration of formaldehyde reaches the 90-100 grams per liter, makes silver nitrate remaining on the fabric fibre all become argent, and the fiber surface structure is strengthened;
In first time during chemical plating, improve copper sulphate, the concentration of sodium potassium tartrate tetrahydrate and b diammonium edta, purpose are to improve the stability of chemical plating fluid, and life cycle is long, and initial reaction speed is fast, and its prescription is:
