Problems solved by technology

[0009] However, in the inventions of the aforementioned Patent Documents 2 to 4, there is no mention of the relationship between the light-modified modified layer of the hard coat layer and the cellulose nanofibers, even if the hard coat layer contains cellulose nanofibers with excellent characteristics. However, it is still impossible to achieve high hardness, flatness and high transparency, and to achieve the effect of high scratch resistance and high weather resistance at the same time

Embodiment 1

[0051] Hereinafter, this embodiment will be described with reference to the drawings.

[0052] Such as figure 1 As shown, in the silicone resin-based hard coating solution (AS4700F manufactured by Momentive: about 27% of the solid content of the silicone resin) 1, cellulose was added at a ratio of 0.4% by weight based on the solid content of the silicone resin. Nanofiber dispersion liquid (average fiber diameter is 10~30nm, and average fiber length is 200~800nm, the dispersion liquid of the cellulose nanofiber of 1% by weight) 2, it is stirred by magnetic stirrer, forms the composition that contains cellulose nanofiber Fiber hard coating solution3.

[0053] On the polycarbonate substrate 4, apply an undercoat solution (SHP470 produced by Momentive) by dip coating, and heat and dry it at 130° C. for 15 minutes to form a 4 μm layer. Thick film undercoat5. On this substrate, the hard coating liquid 3 containing the above-mentioned cellulose nanofibers was coated by the dip coa...

Embodiment 2

[0055] A hard coat layer was prepared in the same manner as in Example 1, and the surface thereof was photomodified, except that a hard coat liquid containing cellulose nanofibers at a ratio of 2.0% by weight relative to the solid content of the silicone resin was used. The thickness of the modified layer was 0.4 μm.

Embodiment 3

[0057] A hard coat layer was prepared in the same manner as in Example 1, and the surface thereof was photomodified, except that a hard coat liquid containing cellulose nanofibers at a ratio of 4.0% by weight to the silicone resin solid content was used. The thickness of the modified layer was 0.3 μm.

Abstract

The present invention provides a resin glass sheet, the surface of which is modified to be glass-like, and a method for manufacturing the same, whereby transparency, scratch resistance, abrasion resistance, and durability with respect to temperature change can be enhanced. In the present invention, a hard coat layer comprising a thermosetting material of a silicone polymer containing cellulose nanofibers is formed on a transparent resin substrate, and a modification layer having a film thickness of more than 0.2 [mu]m and less than 0.6 [mu]m is also formed thereon by irradiating the surface ofthe hard coat layer with vacuum ultraviolet rays having a wavelength of 200 nm or less.

Description

technical field [0001] The present invention relates to a resin glass plate whose surface is modified like glass among transparent resin plates for see-through and lighting, and its manufacturing method. Background technique [0002] Conventionally, polycarbonate substrates have been used as substrates for transparent resin sheets used in windowpanes for vehicles and windowpanes for building materials. This polycarbonate substrate has the following problems, that is, although it is light in weight and excellent in formability compared with glass substrates, its surface is very easily damaged, and deformation due to sunlight, wind and rain, etc. is easy to occur. , discoloration, deterioration. Then, in order to solve this problem, the present inventors proposed the following resin glass plate and its manufacturing method in the previous application, in which a hard coat layer made of a silicone resin polymer is formed on a transparent resin substrate , and by irradiating t...
