Problems solved by technology

[0009] In the conventional method of adding a fluorine-based release agent during molding, the added fluorine-based release agent may bleed out and cause problems such as white turbidity.
In addition, in the method of grafting the surface of the molded article after molding, there may be problems that unevenness is likely to occur on the surface and the operation is complicated.

Embodiment 1

[0339] The surface of pellets (2 mm x 2 mm x 5 mm) of thermoplastic resin COP (cycloolefin polymer) as the resin material was irradiated with low-energy electron beams at an irradiation dose of 20 kGy in a nitrogen atmosphere using an electron beam irradiation apparatus (irradiation conditions). : acceleration voltage 250kV, irradiation current 1mA, sample-irradiation window distance 15mm). Next, the pellets were taken out, placed in a container under nitrogen, and placed in a C which was a fluorine-containing graft compound 6 F 13 CH 2 CH 2 OCOCH=CH 2 The solution (preliminarily deoxidized) was immersed at an internal temperature of 60°C for 4 hours. After immersion, it was washed with acetone and dried to obtain a compound having a perfluoroalkyl group (C 6 F 13 -) of the graft chain molding material (raw material pellets).

[0340] Further, the pellets obtained above were heated and melted at 260° C., and then film-forming was performed under a pressure of 0.0136 MPa...

Embodiment 2～18

[0342] A molding material (raw material pellet) and a film were produced by the same method as in Example 1, except that the resin material, the perfluoroalkyl group of the fluorine-containing graft compound, and the irradiation dose were changed as shown in Table 1.

Abstract

The present invention provides a method for producing a molded body from a molding material, wherein the molding material has a fluorine-containing graft chain.

Description

technical field [0001] The present invention relates to a method for producing a molded body, and more specifically, to a method for producing a resin molded body from a molding material having a fluorine-containing graft chain. Background technique [0002] The resin molded body is used in various fields, such as the fields of medical parts, optical parts, building parts, clothing, packaging, containers, molds, and the like. Various functions, such as water repellency, oil repellency, etc., are added to such a resin molded body according to the application. [0003] Conventionally, as a method of imparting functions such as water repellency and oil repellency to a resin molded body, a method of segregating fluorine on the surface of the obtained molded body by adding a fluorine-based repellant during molding is known (Patent Document 1). ), or a method of grafting a fluorine-containing monomer after irradiating the surface of the molded body with ionizing radiation to gene...
