More specifically, it is applicable to thin methyl methacrylate-styrene copolymer resin compositions suitable for lens thin K, which can be used as, for example, Fresnel lenses and lenticular lenses for screens of projection televisions Or, it is suitable for thin materials of electronic or electrical equipment that must be able to prevent fine dust and the like. »Front dry and less congestion can be used for projecting the transparent sheet for" eaves and the like. When they are placed on the "vision machine, it is necessary to have sufficient stiffness and dimensional stability to suppress the deviation (deflectioiO, even if the sharpness of the wall is reduced to allow the screen to be enlarged and the clarity of the image to be increased. In addition, materials for lenses used in televisions and the like are usually required to have excellent light diffusion properties. Widen the angle of view to obtain clear and easy-to-trace images • and especially to meet this demand "It is better to use a transparent feed sheet with a high refractive index * A conventional sheet that is clear for transparency, What has been used is: acrylic acid resin (PMMA) sheet and polycarbonate resin (PC) sheet * However, in the case of polymethyl methacrylate sheet, the stiffness is high, but the hygroscopicity is also High, so the size stability is poor and the refractive index is as low as 1.49. For these reasons, polymethyl methacrylate flakes are not used for sharpness. In terms of B-, polycarbonate carbonate flakes In the example, hygroscopicity is the opposite Low, so the size stability is excellent and the refractive index is also as high as 1.59❶ However, the stiffness is low, and for this reason, the polycarbonate sheet is not suitable for sharpness. The Ministry of Economic Affairs Central Standard Falcon Bureau employee consumption Printed by the cooperative. (Please read the precautions on the back before filling in this page.) From the aforementioned point of view, this person has already invested irony on the sheet for sharp use, and the result led to the discovery: methacrylic acid Yan · styrene copolymer resin (MS) sheet, which has high stiffness and low moisture absorption and therefore has excellent dimensional stability and proper refractive index of 1.52 to 1.54. It is preferable to use it as a sheet for baking * However, in addition to the physical properties mentioned above, the transparent sheet also needs to have anti-static properties to prevent the deterioration of the image clarity caused by the adhesion of micro-swells on the surface of 2 sharps.

Description of the invention (2) Japan Goku No. 374W / 1989 Yu Jie: Blending methyl methacrylate-styrene (MS > with a sulfonate (e.g. aliphatic sulfonic acid), and then making the obtained blend to prepare flakes • In this case, the antistatic properties of the flakes are excellent, but because the compatibility of MS and sulfonate is very poor, the external ruptures (such as dents and turbid lines on the flakes), and in addition , There are also difficulties in obtaining transparency and other problems. In addition, Japan ’s Japanese Patent Application No. 43440/1991 discloses that PMMA is blended with sulfonate (such as aromatic sulfonic acid) and polyether, and then The obtained blend of tapirs was prepared in chess to prepare flakes, and Japanese Patent Laid-Open Application No. 197552/1989: PMMA was blended with sulfonate and glycerin fatty acid ester, and then the obtained blend was blended It is made of chess to get thin slices. In these cases, the appearance of the flakes can be improved by the compatibility effect of polyether or glycerin fatty acid. However, "to obtain sufficient anti-static mildew" is the need for large sulfonates, polyethers and the like, and therefore has the problem of not being able to tap enough transparency. In this case, if the sheet is formed by using MS instead of PMMA, inconvenient appearance cracks (such as dents and turbid lines) will occur in the sheet. In addition, in Japan's announcement No. 98/1992 Disclosure: Lithium sulfonate and nonionic surfactant are used together as anti-static agents. According to this technique, when PMMA is used, excellent transparency can be obtained, but when MS is used, external ruptures (such as dents and turbid lines) can occur on the thin slices made by MS. The compatibility of the active surfactants is poor. Shi Ming Jia Shu, who has studied it, is expected to overcome the shortcomings of Fu Tong's method of use, and as a result, its b after a is: when the methacrylic acid methacrylate When the copolymer resin is blended with the specific alkylbenzene-sulfonate lithium, the tapir can have special ® anti-static properties and exterior properties, high refractive index and total light transmittance, less color properties and Therefore, translucent sheets with excellent optical properties, excellent physical properties, and dimensional stability · — 4 — ^ paper size is applicable to China National Standard (CNS) A4 specifications (210X297 mm) (please read the note on the back first $ Item and then fill out this page).

So it can improve the appearance of cracking and the tapir has excellent antistatic properties. In addition to this In addition, contrary to PMMA, it does not need to be used with other additives to improve compatibility. The use of lithium metal with the smallest atomic radius as the test metal allows the preparation of thin sheets with excellent transparency and yellowing resistance. It also B found that when blending specific inorganic fine particles or cross-linked organic polymers as a light diffusing agent, it can obtain light diffusivity suitable for sharp, but it will not impair transparency.

Description of the invention (11) Example 8 The test M was obtained by the same steps as Example 1, but the exception is: the methyl group used in Example 1 Methyl acrylate-styrene copolymer resin, lithium dodecyl benzene sulfonate and cross-linked acrylic resin beads [It contains 80% by weight or more and the particle size is 3 ~ 20wb, manufactured by Zhenshui Chemical Industry Co., Ltd., commodity Name: Tecpo] y «> er-SBX-12 (average particle size 12« B)], blended at the ratio shown in Table 3 and in a pressure kneader, cut off the heat to melt and stir The granules were prepared by mixing. Then, using a vent type 65 mm 0 thin H extruder, the test K was made at a resin temperature of 235¾, and then various physical properties were measured. The measured results are shown in Table 3. Comparative Example 1 Test Η was prepared by the same procedure as Example 1. , But the exception is: the methacrylic acid methacrylate copolymer resin used in Example 1 and sodium dodecyl sulfonate are blended in the ratio shown in Table 4 and then measured Different physical properties. The measured results are shown in Table 4. Comparative Example 2 The test piece was prepared by the same procedure as in Example 1, but the exception was: the methacrylic acid used in Ben Example 1 The methyl ester-styrene copolymer resin and sodium dodecyl benzene sulfonate were blended at a ratio as shown in Table 4, and then various physical properties were measured. The measured results are shown in Table 4. Comparative Examples 3 and 4 Test Η was prepared by the same procedure as Example 1, except for the exception: the methyl methacrylate-styrene copolymer used in Example 1 and the dodecylbenzene Sodium sulfonate was prepared by blending in the ratio shown in Table 4, and then various physical properties were measured. The measured results are shown in Table 4. Related to Comparative Example 4 is that the extrusion of the resin is difficult, and therefore the yellowing index, surface specific resistance value, and total light transmittance cannot be measured. Comparative Example 5 Test Η was obtained by the same steps as in Example 1, but the exception is: it will be used in Example -13 ·-This paper scale is applicable to the Chinese National Falcon (CNS) Α4 ^ Grid (210X297 Ali) '(Please read the ^ face notes before filling this page)
