[Industrial Application Field] The present invention relates to a method for producing a synthetic resin molded article having a surface with excellent scratch resistance and antistatic properties. [Prior art] Currently, many synthetic resin molded products are on the market, and although they have many excellent properties, they generally have low surface hardness and low resistance to scratches, so they are difficult to handle during processing and transportation. The surface is easily scratched and scratched, which not only damages the product value, but also when removing dirt such as dirt that adheres to the surface of plastic products with a cloth during use. It is easily scratched, and it is also prone to abrasion scratches due to collisions with other objects, and in extreme cases, these scratches can cause the optical properties to be lost, making it completely unusable, a fatal drawback. It was hot. To address this problem, several methods have already been used industrially to form a scratch-resistant film on the surface of synthetic resin molded products, and the problem has been practically solved in many application fields. ing. However, in applications such as instrument dials and see-through panels, there is an extremely strong demand for synthetic resin molded products that have not only scratch resistance but also antistatic properties. However, with the prior art, a synthetic resin molded product having both scratch resistance and antistatic ability that satisfies market requirements has not been obtained industrially. That is, for example, in Japanese Patent Application Laid-open No. 55-86848,
A compound having three or more (meth)acryloyloxy groups (acryloyloxy group or methacryloyloxy group, hereinafter the same) in one molecule,
A coating that forms a film with both scratch resistance and antistatic properties by irradiating active energy rays in air, which is made of a polymerizable acidic phosphate ester having a (meth)acryloyloxy group and an ethanolamine compound. A material composition is disclosed. However, there are problems with the above method, such as when a large amount of compound is added in order to impart sufficient antistatic ability, cloudiness tends to occur due to what is thought to have bleed onto the surface. There is a need for improvement. [Problems to be Solved by the Invention] Under the current situation as described above, as a result of intensive studies aimed at providing a synthetic resin molded product having sufficient scratch resistance and antistatic properties, we have found that a specific polymerizable product The above-mentioned method can be achieved by forming a cured film on the surface of a synthetic resin molded product using a cross-linked curable resin material made of a compound and a specific polymerizable acidic phosphate ester using a mold made of glass or metal. The inventors have discovered that a synthetic resin molded article that meets the purpose can be obtained, and have arrived at the present invention. [Means for Solving the Problems] The method for producing a synthetic resin molded product having a surface with excellent scratch resistance and antistatic properties according to the present invention is a method for producing a synthetic resin molded product having a surface with excellent scratch resistance and antistatic properties. 90 to 99.8% by weight of a polymerizable compound (A) having at least two acryloyloxy groups and/or methacryloyloxy groups in the molecule;

Hereinafter, the present invention will be explained in more detail with reference to Examples. Parts in the examples represent parts by weight. The scratch resistance is evaluated by the increase in haze value determined by the falling sand method shown below. In other words, the test piece is tilted at an angle of 45° to the horizontal direction and rotated around the vertical axis at a speed of 11 R.PM.
300g of 60 mesh carborundum from 70cm above
is dropped at a speed of 150 g/min, and the increase in haze value is calculated by subtracting the haze value before sand fall from the haze value after sand fall. Note that the haze value is expressed by the following formula. Haze value (%) = total light transmittance - parallel light transmittance / total light transmittance x 100 The smaller the increase in haze value, the better the scratch resistance. Moreover, the antistatic property was expressed by the value of charge half-life measured under the following conditions. That is, after holding the sample for 24 hours under constant temperature and humidity conditions at a temperature of 20° C. and a relative humidity of 50%, a voltage of 10 KV was applied for 10 seconds using an honest meter (manufactured by Shishido Shokai) to measure the half-life. In addition, changes in the appearance of synthetic resin molded products after being left unused will be observed after manufacture at a constant temperature and humidity of 20°C and relative humidity of 50%.
The results of observing the appearance after leaving the sample for a period of time are shown. Example 1 A crosslinked curable resin material consisting of 97.5 parts of 1,4-butanediol diacrylate, 2.5 parts of Kayamer PM 1 (manufactured by Nippon Kayaku Co., Ltd., monomethacryloxyethyl phosphate), and 1.5 parts of benzoin ethyl ether was heated to 610 mm. ×460mm×
Cast on one side of a 6mm (thick) tempered glass plate,
A colorless and transparent methacrylic resin plate (Mitsubishi Rayon Co., Ltd., Acrylite E# 001) heated to 45°C and heated to 45°C was placed on top of it, and a roller was applied from above to ensure that no air bubbles remained between the resin plate and the glass. The resin material coating film was spread to a thickness of approximately 10 μm. First, take the items in such a condition at 75mm intervals.
10 fluorescent chemical lamps arranged (manufactured by Toshiba,
FL-20BL) was irradiated for 1 minute from a height of 6 cm from the methacrylic resin plate side. After that, the glass plate was peeled off from the methacrylic resin plate on which the film was formed, and the side on which the film was formed was then irradiated for 30 seconds from a height of 20 cm using two high-pressure mercury lamps (manufactured by Toshiba, H2000L) arranged at 400 mm intervals. The film was then post-cured. The scratch resistance of the film-formed side of the resin plate obtained in this way showed an increase in haze value of 11% using the head drop method, and a charge half-life of 2 seconds, indicating excellent scratch resistance and antistatic properties. Also, no change in appearance was observed after being left alone. The increase in haze value on the surface of the resin plate on which the film is not formed is 55%, and the charge half-life is 120%.
It was hot for more than a second. Example 2 The cross-linked curable resin material used in Example 1 was 610 mm thick.
A 1 mm thick brown smoke colored polycarbonate resin plate (Mitsubishi Rayon Co., Ltd.) was cast on one side of a 460 mm x 6 mm (thick) tempered glass plate.
(Dialite 1530) was placed on top of the resin plate and spread with a roller so that no air bubbles remained between the resin plate and the glass, so that the resin material coating film had a thickness of approximately 8 μm. First, remove the item in such a condition from 75
The glass side was irradiated for 1 minute from a height of 6 cm using 10 fluorescent chemical lamps (FL-20BL, manufactured by Toshiba) arranged at mm intervals. After that, the glass plate was peeled off from the polycarbonate resin plate on which the film was formed, and then the film-formed side was exposed to the film-formed side for 30 seconds from a height of 20 cm using two high-pressure mercury lamps (manufactured by Toshiba, H2000L) arranged at 400 mm intervals. The coating was post-cured by irradiation. The scratch resistance of the surface on the non-coated side of the resin plate obtained in this way is determined by the increase in haze value in the sand drop method.
67%, and the charge half-life was more than 120 seconds,
Regarding the scratch resistance of the surface on which the film is formed, the haze value increases by 12% using the sand drop method, the charge half-life is 2 seconds, and the scratch resistance and antistatic properties are excellent. No change in appearance was observed. Comparative Example 1 The same film raw material as in Example 1 was heated to 45°C.
The cross-linked curable resin material in Example 1 was applied to one side of a 610 mm x 460 mm x 6 mm (thickness) methacrylic resin plate (Mitsubishi Rayon Co., Ltd., Acrylite E # 001),
The top is covered with a taut polypropylene film cover with a thickness of 20 μm, and the film is spread from above using a roller so that no air bubbles remain between the film and the resin plate, until the thickness of the resin material coating is approximately 20 μm. I made it so. Then, it was cured under the same curing conditions as in Example 1 to obtain a resin plate having a cured film on one side. The abrasion resistance of the surface of the obtained resin plate on which the film was formed showed that the haze value increased by 12% by the sand drop method, and the charge half-life was 45 seconds. Example 3 The same procedure as in Example 1 was repeated using a stainless steel plate as the mold and changing the composition of the cross-linked curable resin material as shown below to produce a resin plate with a hardened film on the surface. I got it. The scratch resistance of the film-formed side of the obtained resin plate showed an increase in haze value of 11% and a charge half-life of 2 seconds, showing excellent scratch resistance and antistatic properties.
No change in appearance was observed after standing. Crosslinked curable resin material composition Trimethylolpropane triacrylate 50.0 parts 1,6-hexanediol diacrylate 47.5 parts Kayamer PM 1 2.5 parts Benzoin ethyl ether 1.5 parts [Effects of the Invention] As described above, by the method of the present invention Since the resulting synthetic resin molded product has both scratch resistance and antistatic properties, it is particularly preferable to have both, as well as for applications that require scratch resistance or antistatic properties alone. , instrument scale plate,
Suitable for use in transparent panels, CRT front panels, etc.
