Reinforced composite film and manufacturing method therefor

Abstract

The present invention relates to: a reinforced composite film, which can be manufactured at low cost and has very remarkable durability and physical properties such as restorability, flexibility, lightweightness, water resistance, and heat resistance, is prevented from being easily torn or damaged even if an external force is applied thereto, and can be semi-permanently used even if repeatedly bent; and a manufacturing method therefor. According to the present invention, the reinforced composite film comprises: a first flexible layer and a second flexible layer which have flexibility; a mesh layer located between the first flexible layer and the second flexible layer; and main binding layers for binding the first flexible layer, the mesh layer and the second flexible layer, wherein the first flexible layer and the second flexible layer have joint parts that are positioned to face each other and are penetratively formed in a predetermined shape such that the mesh layer can be exposed tothe outside. In addition, according to the present invention, a method for preparing the reinforced composite film comprises: a preparation step of positioning a pair of main binding layers between apair of flexible layers having flexibility, forming penetrated joint parts in a predetermined shape on the flexible layers and the main binding layers, and positioning a mesh layer between a pair ofthe main binding layers; and a main binding step of binding a pair of the flexible layers and the mesh layer by melting a pair of the main binding layers.

Description

technical field [0001] The present invention relates to a composite reinforced film and a preparation method, and more specifically relates to the following composite reinforced film and a preparation method. According to the composite reinforced film of the present invention, it can be produced at a low price, and has durability, resilience, flexibility, and light weight. , Water resistance, heat resistance and other physical properties are very excellent, even if it is subjected to external force, it is not easy to tear or break, not only that, even if it is bent repeatedly, it can be used semi-permanently. Background technique [0002] Hereinafter, for convenience of explanation, the present invention will be described using a toy, but the present invention is not limited to the toy, and is applicable to various fields. [0003] Various children's toys are sold on the market. These toys come in a variety of materials, sizes, and shapes depending on the type. Recently, ma...

Problems solved by technology

[0005] However, in terms of the characteristics of paper, there are problems that it is afraid of water, and it cannot maintain its original shape when it is repeatedly bent and unfolded, and it will be wrinkled or torn.

[0006] In particular, in the case where the structure that plays the role of repeatedly bending joints among the toy parts is formed of paper, after a certain period of time, it is separated into multiple layers along the grain or is torn. limited use
