Abstract

PURPOSE:To improve the adhesion strength of both a polypropyrene based film and a substrate by a pressure lamination of the polypropyrene based film extruded from a T die at 200-330 deg.C on the substrate anchor-coated after it is subjected to an ozone treatment. CONSTITUTION:A polypropyrene based resin is extruded from a T die at 200- 330 deg.C to form a melted thin film, subjected to an ozone treatment on one side thereof by blowing air with the ozone concentration of 14g/cm<2> and laminated monolithically on a substrate coated dry with an isocyanate based anchor coat agent with a pressure laminator. As the extrusion and ozone treatment are done at a specified temperature, this provides a film adhesion with a metal foil and various resin films other than the substrate having an anchoring effect such as paper and cloth.

1) Industrial application field The present invention relates to an extrusion lamination method of propylene resin, and more specifically, to a base material made of a material different from the propylene resin. Related to lamination methods. 2) Conventional technology Conventionally, anchor coating agents have been applied to various types of base materials such as resin films, metal foils, paper, and cloth in order to impart heat sealability, moisture resistance, etc. to these base materials. , extrusion lamination of ethylene-based resins such as polyethylene has been carried out. On the other hand, propylene-based resins such as polypropylene, which have superior mechanical properties such as rigidity and surface strength compared to ethylene-based resins, can be used as substrates made of homogeneous materials such as biaxially oriented polypropylene, polypropylene woven fabric, etc., and paper. , woven fabric,
Although similar extrusion lamination is possible for very limited base materials such as nonwoven fabrics that can be expected to have an anchor effect, it is possible to use various resin films, metal foils, etc. made of materials different from propylene resins. At present, extrusion lamination is not carried out for the base materials of 1 to 3 because substantially sufficient adhesive strength cannot be obtained. 3) Problems to be Solved by the Invention In view of the above-mentioned current situation, the present invention provides a base material made of the same material as the propylene resin and a base material 3 that can be expected to have an anchor effect when extrusion laminating propylene resin. Extrusion laminates are used to obtain propylene resin laminates that exhibit excellent adhesive strength even to substrates made of different materials and have excellent physical properties such as heat sealability. This was done for the purpose of providing a method. 4) Means to solve the problem In the propylene resin extrusion lamination method of the present invention, the propylene resin is passed through the die of an extruder at a resin temperature of 200 to 300 ml.
It is characterized in that it is extruded at 30° C. to form a molten thin film, then treated with ozone, and then pressure-bonded and laminated onto an anchor-coated substrate using the treated surface as an adhesive surface. The propylene-based resin in the present invention includes all propylene homopolymers and propylene-based copolymers; typical examples include polypropylene,
Examples include random copolymers such as propylene-ethylene, propylene-butene-1, propylene-ethylene-butene-1, and the like, and these may be used in combination with each other. The melt flow rate of these propylene resins is not particularly limited as long as it can be processed by extrusion lamination, but is usually 0.01 to 30 (1/10 min, preferably 0.1 to 100 f/10 min, more preferably is 0
.. 5-50? /10 minutes. In addition, these propylene resins can be mixed with ethylene resins such as low density polyethylene and rubbers such as ethylene-propylene rubber in order to improve their extrusion lamination processability (spreadability, neck-in, etc.). Antioxidants, heat stabilizers, ultraviolet absorbers, slip agents, antistatic agents, antifogging agents, colorants, and the like can be added as necessary in amounts that do not excessively reduce the adhesive strength with the base material. In the present invention, when extruding the propylene resin through the extruder to form a molten thin film, the resin temperature is set at 20°C.
A temperature of 0 to 330°C is essential and, yes, preferable! d2
The temperature is preferably 00 to 300°C, more preferably 200 to 280°C. If the temperature is less than 200° C., the resin itself has poor spreadability and a molten thin film cannot be obtained smoothly, and the adhesive strength with the base material is insufficient. Furthermore, if the temperature exceeds 330°C, the adhesive strength with the base material will decrease. In the present invention, it is essential to subject the adhesive surface of the molten thin film to a base material (described later) within the air gap to ozone treatment. Ozone treatment ID: Directs ozone-containing gas (air, etc.) from a nozzle or slit-shaped outlet toward the molten thin film surface, or toward the substrate surface (described later), or between the molten thin film and the substrate. This is done by spraying it towards the crimped area. In addition, when carrying out extrusion lamination at a high speed of 100 m/min or more, it is preferable to spray toward the crimped part of the molten thin film and the base material. The concentration of ozone in the gas to be blown is preferably 11/Z or more, more preferably Hr1
It is 3y/n1 or more. Further, the amount of spraying is preferably at least 0.0 sz/min/cm, more preferably 0.1 t1 min/cm, relative to the width of the molten thin film. In this case, it should be avoided to increase the flow rate to an extremely high level since this will cause the molten thin film to oscillate and become uneven in thickness. Next, the molten thin film treated with ozone by the method described above is guided to a pressure roll, and the treated surface is used as the adhesive surface.
