The present invention relates to a method for treating a thermoplastic resin, and more particularly to a method for treating a thermoplastic resin, which is characterized by subjecting the thermoplastic resin to a low-temperature plasma treatment at a specific temperature. Thermoplastic resins are used in many fields because they have excellent physical properties and are easy to mold. However, because thermoplastic resins such as polyolefins have low polarity, they have poor adhesion, paintability, printability, plating properties, etc., and in order to improve these problems, surface treatment of the resins is sometimes performed. many. As surface treatment methods for thermoplastic resins, chromic acid mixture treatment, corona discharge treatment, flame treatment, etc. are known. However, the treatment method using a chromic acid mixture has problems in the treatment of waste liquid, and other treatment methods have problems such as limitations on the thermoplastic resins that can be applied. Therefore, low-temperature plasma processing has recently attracted attention as a new processing method. As a method to efficiently perform surface treatment of thermoplastic resin by this low-temperature plasma treatment, the surface temperature of thermoplastic resin is
It has been proposed to carry out the process at a relatively high temperature of 100°C (Japanese Patent Laid-Open No. 115431/1983). However, in order to avoid deformation of thermoplastic resin molded products, this method
It is necessary to set the upper limit to a temperature that is 10°C or more lower. On the other hand, when manufacturing a laminate using two or more different types of thermoplastic resins, methods such as pasting them together using an adhesive or coextruding an adhesive resin between both resins are adopted. There is. However, this method has problems such as requiring an adhesive as a third component and requiring extrusion equipment for adhesive resin. The object of the present invention is to provide a method for treating thermoplastic resins that eliminates all of the above-mentioned drawbacks, and which provides excellent effects from low-temperature plasma treatment and which treats thermoplastic resins that have undergone this treatment. This makes it possible to obtain a resin laminate by utilizing surface activity. The present invention provides a method for treating a thermoplastic resin, which comprises subjecting the thermoplastic resin to a low-temperature plasma treatment at a temperature higher than the melting point or softening point of the resin. The thermoplastic resin to which the present invention is applied is not particularly limited, and includes, for example, high-density polyethylene, low-density polyethylene, polypropylene, copolymers of two types of olefins, and copolymers of olefins and unsaturated carboxylic acids or derivatives thereof. Polyolefins such as polyesters; polycarbonates; polyamides; polystyrene resins such as general-purpose polystyrene (GP-PS), high-impact polystyrene (HI-PS), AS resins, and ABS resins; polyvinyl chloride; acrylic resins, etc. can. These thermoplastic resins may be used alone or in combination of two or more. In addition, thermoplastic resins include various stabilizers (oxidation, heat, light, etc.), fillers (calcium carbonate, talc, clay, etc.), reinforcing materials (glass fiber, carbon fiber, etc.), rubbers, A lubricant, an antistatic agent, a plasticizer, etc. can be added as appropriate. In the present invention, the thermoplastic resin is subjected to low-temperature plasma treatment at a temperature above the melting point of the crystalline resin and above the softening point (or glass transition temperature) of the amorphous resin. Therefore, for molded products, the surface temperature is raised by heating as described above, and in the case of extrusion molding, low-temperature plasma treatment is performed before cooling the thermoplastic resin extruded from the die. . Here, low-temperature plasma refers to non-equilibrium plasma, and specifically, it is produced by high-frequency discharge, glow discharge, microwave discharge, corona discharge, etc., such as air, oxygen, nitrogen, hydrogen, argon, helium, Nitric oxide, methane, ethane, freon,
It is obtained by activating ethylene, acrylonitrile, acrylic acid, benzene, tetrafluoroethylene, tetramethylsilane, tetramethyltin, etc., and mixed gases thereof. Low temperature plasma treatment is 0.005~20 Torr,
The above discharge is preferably carried out under a pressure of 0.02 to 5 Torr, and the thermoplastic resin is treated with the resulting low temperature plasma for a predetermined period of time, usually from 1 second to 10 minutes. After the low-temperature plasma treatment, the temperature of the thermoplastic resin is lowered to a predetermined temperature in the case of molded products, and in the case of unmolded products, it is molded into sheets, films, etc. by pressure treatment. In that case, it may be laminated with other materials such as resins and metals. If the material to be laminated with the low-temperature plasma-treated thermoplastic resin is another thermoplastic resin, the resin may also be subjected to the low-temperature plasma treatment as described above, and the treated surfaces of the resins may be laminated by overlapping each other. desirable. Lamination is performed under vacuum or non-vacuum. In the present invention, as mentioned above, it is necessary to perform low-temperature plasma treatment on the thermoplastic resin at a temperature higher than the melting point or softening point, and even if the thermoplastic resin is treated at a temperature lower than the above temperature, the desired effect cannot be sufficiently obtained. do not have. According to the present invention, the surface modification effect of thermoplastic resin is high, and properties such as paintability, printability, plating performance, and adhesiveness are improved, and when manufacturing a laminate, adhesive resin is not used. A laminate with excellent adhesive strength can be obtained. Furthermore, bonding can be carried out in a clean atmosphere free of impurities and air, resulting in a high-quality product. The method of the present invention can be incorporated and integrated into the process of forming sheets, films, etc., thereby reducing equipment costs. Another feature is that the product obtained by the present invention is free from warping and deformation. Next, the present invention will be explained in detail with reference to examples. Example 1 A sheet of GP-polystyrene (melt index (MI) 3.8 g/10 minutes) was inserted into a plasma treatment chamber, heated to 210°C, maintained at this temperature, and depressurized to 1 × 10 -2 Torr. . Next, while flowing nitrogen gas at a rate of 50 c.c./min, the pressure was adjusted to 1 Torr, and low-temperature plasma treatment was performed at a discharge output of 50 W for 60 seconds. This treatment reduces the contact angle of water on the sheet surface to 39
The contact angle was 86 degrees before treatment, indicating an increase in hydrophilicity compared to the contact angle of 86 degrees before treatment. Example 2 In Example 1, high-density polyethylene (density 0.965 g/cm 3 , MI 14 g/cm 3 ) was used instead of GP-polystyrene.
10 minutes) and the heating temperature was 190°C. The water contact angle of the molded article after treatment was 61 degrees.
Note that the contact angle before treatment was 100 degrees. Examples 3 to 7 The thermoplastic resins shown in Table 1 were heated and maintained at predetermined temperatures, and subjected to low-temperature plasma treatment according to Example 1. Next, in a plasma processing chamber, two types of resins A and B were successively stacked on top of each other with their respective treated surfaces facing inside, and pressurized to obtain a laminate. The results of measuring the 180 degree peel strength of the heat-sealed part of the obtained laminate were compared with the results for the untreated sample.
Shown in the table.
