Abstract

PURPOSE:To permit to weld integrally by fusion welding strongly without spoiling the function, commercial value and the like of the molded body substantially after fusion welding by a method wherein polyarylate resin is used together with polyethylene terephthalate resin upon welding the molded products of polyethylene terephthalate resin mutually by supersonic fusion welding. CONSTITUTION:The molded products, consisting of independent or mixed resin of polyethylene terephthalate and polyarylate, are welded by pressure and fusion by contacting a supersonic vibration horn to either one of the molded products. The molded product 1, to which the supersonic vibration horn 4 is contacted, is composed of a resin blended with 30wt% or more of polyarylate resin and, whereby, the thermal deformation temperature of the molded product is increased without spoiling the transparency of the polyethylene terephthalate resin and good fusion welding can be effected by applying supersonic vibration. On the other hand, in case the blended amount is less than 30wt%, the fusion welding becomes insufficient.

難であった。Among these methods, the ultrasonic welding method involves bringing a horn vibrating at an ultrasonic frequency into contact with one of the molded products to be welded, applying ultrasonic vibration to one of the molded products, and applying vibrational energy to the contact surface between the molded products. This method uses the energy generated to melt the contact surfaces of the molded products and weld them together as one unit.This method is easy to install, and it is said that a strong and clean adhesive finish can be obtained in a short period of time. Due to its unique characteristics, it has recently been used as a method for joining various synthetic resin materials. However, when this welding method is applied to welding polyethylene terephthalate 41) 1 resin molded products together,
It is not possible to form a strong, integrated weld. In other words, polyethylene terephthalate resin has a melting point of around 255°C, but when heated, it easily softens below the melting point. Therefore, by applying an ordinary ultrasonic welding method, welding is performed by applying ultrasonic vibrations to the molded products under pressure. If this is done, the resin on the joint surface will soften before it melts, and even if ultrasonic vibrations are applied, the same heat generation as before softening will no longer occur and the resin will not be able to melt, resulting in the melting of the resin. is not carried out,
Furthermore, since the molded product is pressurized in such a state, the molded product is deformed, making it difficult to obtain an integrally welded product in the desired shape.

Furthermore, for applications using molded bodies after welding, it is desirable to use a material that does not impair the properties of polyethylene terephthalate. From this point of view, we conducted various investigations and found polyarylate resin as a suitable material.

(As a result of performing ultrasonic welding on molded products with a fat composition, we found that depending on the amount of polyarylate resin blended and the way in which ultrasonic vibrations are applied, welding may be either complete or insufficient. It is complete.

は近い方がより一体溶着し易く望ましい。According to the present invention, among the molded products subjected to ultrasonic welding, the molded product on the side in contact with the ultrasonic vibration horn has a resin composition blended with polyarylate resin in an amount of 30% by weight or more. +-VI4a
The heat deformation temperature of the molded product increases without impairing the transparency of S, and good welding occurs when ultrasonic vibration is applied.
Polyethylene terephthalate VJ4II! This makes it possible to eliminate poor welding and softening deformation that can occur when using a single method. On the other hand, if the blend amount is less than 30% by weight, the above effects will be insufficient and welding will be insufficient. Boria relay 1-4 is also a molded product to be welded! The more fat content there is on the side that comes in contact with the ultrasonic vibrating horn, the more efficiently the ultrasonic vibration energy is transmitted, the heat generated on the contact surface increases, and the whole thing is FF! I @ is desirable because it is easy to carry out, and even if the polyarylate resin content in the molded product on the side that the ultrasonic vibration horn contacts is 30 or more, the polyarylate resin content in the other molded product The smaller the number, the more desirable it is, and the closer the resin compositions of both molded products, the easier it is to weld them together, which is desirable.
