Abstract
The invention discloses a method for chemically plating copper without palladium on a polyester film, comprising the following steps: firstly removing oil on the polyester film, and optically grafting crylic acid onto the surface of the polyester film by a grafting method, so as to improve the hydrophilism and activity of the surface; then soaking by utilizing ammonia water and a nitric acid sliver solution for activating; and finally carrying out chemical copper plating to realize the metallization of the surface of the polyester film. The method is simple to operate and easy to realize. By utilizing the method, the plasma processing equipment and palladium chloride can be omitted, thereby being beneficial to lowering the cost; and the method can be applied to preparing metal line patterns by an addition process in the circuit board industry.
Description
Technical field
The invention belongs to the metallized technical field of non-metal material surface, relate to a kind of method of on polyester film, not having the palladium electroless copper.
Background technology
Polyester (polyethylene terephthalate; English abbreviation is PET), belong to general engineering plastic, nineteen forty-one has been since raw material makes fiber first by British J.R. Whenfield and J.T. Dikson with terephthalic acid and terepthaloyl moietie; Obtained gradually using widely; Its membrane product (polyester film, PET film) owing to nontoxic, weathering resistance, chemicalstability is good and have the favor that extremely excellent mechanical property receives circuit-board industry, can be used for making FPC.
But because polyester film wetting ability difference and surface inertness must could carry out electroless copper on its surface through processing such as surface coarsening (like plasma treatment), activation.Use the most general activation method " two-step approach " and " single stage method " arranged." two-step approach " is exactly that the PET film is earlier at SnCl
2Carry out sensitization in the solution and handle, then at PdCl
2Activation in the solution; In order to reduce operation, develop " single stage method ", promptly use SnCl separately
2-PdCl
2The colloid activation solution.More than two kinds of methods, though can on PET, cause the deposition of copper, certain degree of difficulty is arranged, be difficult for deposition and go up copper.In addition, because the PdCl that uses
2Cost an arm and a leg, and relate to SnCl again
2Use, activation system is unstable.
Summary of the invention
The objective of the invention is to overcome the deficiency that palladium catalyst costs an arm and a leg in the electroless copper, the apparatus for processing plasma cost is higher, a kind of method of on polyester film, not having the palladium electroless copper is provided.Can realize the no palladium electroless copper of PET film, its technical process is following: PET film oil removing → PET film load light trigger → UV-light causes gas phase graft acrylic acid → activation → electroless copper.Concrete a kind of method of on polyester film, not having the palladium electroless copper may further comprise the steps:

(3) UV-light causes the gas phase graft acrylic acid: have the PET film of BP to put in the reaction unit load, the reaction unit synoptic diagram is as shown in Figure 1, and wherein 1 is acrylic acid solution, and 2 is uv lamp, and 3 for answering container, and 4 is polyester film (PET film).Used uv lamp power is 9 watts or 15 watts, and predominant wavelength is 254nm.If the uv lamp that uses is 9 watts, then the PET film of BP and the distance of uv lamp are arranged is 1.0～2.0cm in load, and the time of UV-irradiation is 5～30 minutes; If the uv lamp that uses is 15 watts, then the PET film of BP and the distance of uv lamp are arranged is 1.0～5.0cm in load, and the time of UV-irradiation is 5～15 minutes.The massfraction of used acrylic acid solution is 10%～50%.
UV-light initiation grafting acrylic acid is a vapor phase process, promptly has load the PET film of BP to put in the reaction unit that is filled with the vinylformic acid steam, initiation grafting vinylformic acid under UV-irradiation.The vinylformic acid steam is through the mode of high pure nitrogen to the acrylic acid solution bubbling produced.
(4) activation: UV-light is caused PET film behind the gas phase graft acrylic acid put in the zero(ppm) water ultrasonic cleaning into 2～3 minutes; Put the pH value then into and be that normal temperature soaked 10～20 seconds down in 11.50～12.00 the ammonia soln, put the AgNO that concentration is 0.5～1.0g/L again into
3Normal temperature soaked 10～30 seconds down in the solution, put in the zero(ppm) water under the normal temperature soaking and washing at last into 2～5 seconds.
(5) electroless copper: the PET film after the activation put into carry out electroless copper in the chemical bronze plating liquid.The use temperature of chemical bronze plating liquid is 40～50 ℃, and using the pH value is 12～13, and the time of electroless copper is 2～10 minutes.Consisting of of used chemical bronze plating liquid: Salzburg vitriol 16g/L; Seignette salt 14g/L; EDTA Disodium 19.5g/L; Sodium hydroxide 14g/L; Formaldehyde 15mL/L.
Beneficial effect of the present invention: the present invention proposes with methods such as grafting, absorption, cause the electroless copper process.Its technical process is: with absolute ethyl alcohol or acetone PET is carried out oil removal treatment earlier, then load light trigger UVNUL MS-40 (BP), initiation grafting Acrylic Acid Monomer under UV-irradiation afterwards.Can carry out chemisorption to silver ions behind the Acrylic Acid Monomer in the grafting of pet sheet face, thereby reach the activatory purpose.
The present invention need not to use plasma processing, and technology is simple, and uses AgNO
3Replace PdCl
2As the catalyzer of electroless copper, help reducing cost.
