Abstract
The cover tape production process for the carrier tape of a surface-mount electronic device comprises the following steps: (a) applying an adhesive agent uniformly on the corona surface of a polyester film, and oven-drying at a temperature of 100 to 120 DEG C; (b) applying a molten hot-melting adhesive uniformly on the adhesive agent surface; (c) cooling the polyester film coated with hot-melting adhesive; and (5) dividing the cooled polyester film into strips by a strip-dividing machine and coiling the strips by a coiling machine. The production process has the advantages of simple process, low production cost and high quality.
Description
Technical field
The present invention relates to the packaging material field.
Background technology
The packing of surface sticking device such as integrated circuit, electric crystal, diode is that surface sticking device is put into the packing carrier band that is shaped by PS, ABS, PC plastics plastic uptake at present, to pack carrier band surface opening place with cover tape again seals, the cover tape of required surface sticking device packing carrier band costs an arm and a leg mainly by import on the existing domestic market.
Summary of the invention
Purpose of the present invention be exactly cover tape at surface sticking device required on present domestic market packing carrier band mainly by import, the deficiency that costs an arm and a leg and a kind of processing technique of surface sticking device load belt and cover belt is provided, the step of its production technology is:
A. coating adhesive: adhesive is evenly coated on the polyester film corona surface, oven dry then, bake out temperature is 100-120 ℃;
B. be coated with PUR: the molten state PUR is uniformly coated on the adhesive faec;
C. cooling: the polyester film cooling that will coat PUR;
D, itemize, rolling: with the polyester film of cooling by banding machine and winder itemize, rolling.
Also electrostatic agent can be coated with evenly respectively on the PUR face on the non-corona surface of polyester film and on the polyester film.The factory formula of PUR is: low density polyethylene (LDPE) 40-60 gram, vinyl acetate 20-40 gram, tackifier 20-30 gram. the factory formula of electrostatic agent is: both sexes antistatic additive 10-20 gram, absolute ethyl alcohol 50 grams, deionized water 100 grams.
Advantage of the present invention is: production technology is simple, and production cost is low, the quality height.
The specific embodiment
Surface sticking device load belt and cover belt is made up of laminated polyester film, adhesive layer, hot melt adhesive layer and two layers of electrostatic layer, and polyester film selects for use its one side to pass through the polyester film of sided corona treatment, and thickness is 30 microns.Adhesive layer is coated on the corona surface of laminated polyester film, and hot melt adhesive layer is coated on the adhesive layer, and one deck electrostatic layer is coated on the hot melt adhesive layer, and another layer electrostatic layer is coated on the non-corona surface of laminated polyester film.
During production, with low density polyethylene (LDPE) 50 grams, vinyl acetate 30 grams, tackifier 25 gram mixings promptly make PUR.With both sexes antistatic additive 15 grams, absolute ethyl alcohol 50 grams, deionized water 100 gram mixings promptly make electrostatic agent.Adhesive is commercial product, and concrete implementation step is as follows:
A. be coated with electrostatic agent: electrostatic agent is evenly coated on the non-corona surface of polyester film, and coating quantitatively is 10 gram/M
2, oven dry then, bake out temperature is 100-120 ℃;
B. coating adhesive: adhesive is evenly coated on the polyester film corona surface, and coating quantitatively is 30 gram/M
2, oven dry then, bake out temperature is 100-120 ℃;
D. be coated with PUR: the molten state PUR is uniformly coated on the associativity resin face, and the hot melt adhesive layer coating thickness is 30 microns;
E. cooling: the polyester film that coats PUR is set to-20 ℃ chill roll by water temperature and cools off fast;
F. be coated with electrostatic agent: electrostatic agent is uniformly coated on the polyester film on the PUR face, and coating quantitatively is 30 gram/M
2, oven dry then, bake out temperature is 100-120 ℃;
Product specification is: thickness 60-65 micron, and width is respectively 5.3mm, 9.3mm, 13.3mm, 21.3mm, 25.5mm, 37.5mm, 49.5mm, 66.5mm, 82.5mm; Length is 300-500 rice. the performance of its product is: tensile strength 2.0 ± 0.5kg f/9.3mm, adhesive strength 40-60g f/9.3mm, surface resistivity 10
9-10
