一种PMMA树脂材料、光学产品及其制备方法和在制备光学产品中的应用A kind of PMMA resin material, optical product and preparation method thereof and application in preparing optical product 技术领域technical field
本发明属于塑胶制品技术领域，具体涉及一种PMMA树脂材料、光学产品及其制备方法和在制备光学产品中的应用。The invention belongs to the technical field of plastic products, and in particular relates to a PMMA resin material, an optical product, a preparation method thereof and an application in preparing the optical product.
背景技术Background technique
为了可真实再现摄影物体的反差，摄像设备通过需要利用中性光学滤光片对光线进行均匀过滤，使得一定波长范围内的光线具有相同或相近的减小效果。故对中性光学滤光片的过滤效果具有较高的要求：一方面要求中性光学滤光片只会对光线进行减弱，而不会对摄影物体的颜色产生其它影响；另一方面要求其中性过滤的波长范围较宽以满足各种波段范围的使用需求。In order to truly reproduce the contrast of photographic objects, the camera equipment needs to use neutral optical filters to uniformly filter the light, so that the light within a certain wavelength range has the same or similar reduction effect. Therefore, there are high requirements for the filtering effect of the neutral optical filter: on the one hand, it is required that the neutral optical filter will only weaken the light, and will not have other effects on the color of the photographed object; on the other hand, it is required that the neutral optical filter The wavelength range of the filter is wide to meet the needs of various band ranges.
光学玻璃滤光片是常用的中性光学滤光片，但其存在较大的局限。一方面，玻璃材质的滤光片需要经高温熔融成型，对设备要求高，制备工艺复杂，成本较高；另一方面，其可中性过滤的波段范围较窄，且中性过滤并不佳，还存在较大的提升空间，限制了其多元化的应用(例如CN105523713A)。Optical glass filters are commonly used neutral optical filters, but they have major limitations. On the one hand, the glass filter needs to be melted and formed at high temperature, which requires high equipment, complicated preparation process, and high cost; on the other hand, its neutral filter range is narrow, and the neutral filter is not good. , there is still a large room for improvement, which limits its diversified applications (eg CN105523713A).
专利CN111522087A通过在玻璃基底上直接生长石墨烯薄膜来得到中性密度滤光片，虽大大拓宽了中性过滤的波段范围，但其仍是以玻璃材质为基础，同样存在对设备要求高，制备工艺复杂，成本较高，无法多元化的应用问题。The patent CN111522087A obtains a neutral density filter by directly growing a graphene film on a glass substrate. Although the wavelength range of the neutral filter is greatly widened, it is still based on glass material, and there are also high requirements for equipment. The process is complex, the cost is high, and the application problems cannot be diversified.
因此，开发一种在较宽的波段具有更为优异的中性过滤效果，且加工程序简单，成本低廉的新型滤光材料具有重要的研究意义和应用价值。Therefore, it is of great research significance and application value to develop a new type of filter material that has a more excellent neutral filter effect in a wider wavelength band, and has a simple processing procedure and low cost.

The PMMA resin material provided by the present invention is compounded with polymethyl methacrylate and a specific transmittance modifier, and the obtained PMMA resin material has a good neutral filtering effect in a wide range of wavelengths, and has easy The processing has the advantages of low cost and can be widely used in the preparation of optical products (such as optical filters, video cameras or digital cameras).

为实现上述发明目的，本发明采用如下技术方案：In order to realize the above-mentioned purpose of the invention, the present invention adopts following technical scheme:
一种PMMA树脂材料，包括如下重量份数的组分：A kind of PMMA resin material, comprises the component of following parts by weight:
聚甲基丙烯酸甲酯100份；100 parts of polymethyl methacrylate;
分散剂0.03～1.0份；Dispersant 0.03～1.0 parts;
抗氧剂0.03～1.0份；Antioxidant 0.03～1.0 parts;
透过率改性剂0.03～0.11份；Transmittance modifier 0.03-0.11 parts;
所述透过率改性剂由CuCr 2O 4和Cr 2O 3组成，所述透过率改性剂中CuCr 2O 4和Cr 2O 3的重量比为(2～11):1，所述CuCr 2O 4的D50粒径为0.2～1.2μm。 The transmittance modifier is composed of CuCr 2 O 4 and Cr 2 O 3 , the weight ratio of CuCr 2 O 4 and Cr 2 O 3 in the transmittance modifier is (2～11):1, The D50 particle size of the CuCr 2 O 4 is 0.2-1.2 μm.
本发明提供的PMMA树脂材料通过聚甲基丙烯酸甲酯和特定的透过率改性剂复配，得到的PMMA树脂材料在较宽的波段范围内具有较好的中性过滤效果，且具有易加工，成本低的优点，可广泛应用于制备光学产品(例如滤光片、摄像机或数码相机)。The PMMA resin material provided by the present invention is compounded with polymethyl methacrylate and a specific transmittance modifier, and the obtained PMMA resin material has a good neutral filtering effect in a wide range of wavelengths, and has easy The processing has the advantages of low cost and can be widely used in the preparation of optical products (such as optical filters, video cameras or digital cameras).
具体地，以聚甲基丙烯酸甲酯(PMMA)为基础体系，PMMA具有优异的硬度和表面耐划伤性能，另外还具有高透明度，低价格，易于机械加工等优点，是玻璃的理想替代材料。故本发明尝试以聚甲基丙烯酸甲酯为基体，并对其进行改性，以实现可控的中性滤光性能。Specifically, based on polymethyl methacrylate (PMMA), PMMA has excellent hardness and surface scratch resistance, and also has the advantages of high transparency, low price, and easy machining, and is an ideal substitute for glass. . Therefore, the present invention attempts to use polymethyl methacrylate as a matrix and modify it to achieve controllable neutral light filtering performance.
研究发现，在聚甲基丙烯酸甲酯体系中，添加CuCr 2O 4可实现425-775nm透过率曲线相对平坦，但775-1025nm波段透过率波动明显；CuCr 2O 4的粒径对透过率有较大的影响，如粒径过大，遮盖力强，着色力变差，透过率偏低，且透过率波段较大；如粒径过小，分散性差，750-1025nm波段透过率逐渐偏高。添加Cr 2O 3可实现750-1025nm波段透过率曲线相对平坦。通过将CuCr 2O 4和Cr 2O 3复配，并调控两者的用量配比及CuCr 2O 4的粒径，可赋予PMMA体系在425～1025nm光谱波段等量吸收入射光，具有优异的中性过滤效果，可广泛应用于制备光学产品(例如滤光片、摄像机或数码相机)。 The study found that in the polymethyl methacrylate system , adding CuCr 2 O 4 can make the 425-775nm transmittance curve relatively flat, but the transmittance in the 775-1025nm band fluctuates significantly; The pass rate has a great influence, such as too large particle size, strong hiding power, poor coloring power, low transmittance, and large transmittance band; if the particle size is too small, poor dispersion, 750-1025nm band The transmittance is gradually higher. Adding Cr 2 O 3 can achieve a relatively flat transmittance curve in the 750-1025nm band. By compounding CuCr 2 O 4 and Cr 2 O 3 , and adjusting the dosage ratio of the two and the particle size of CuCr 2 O 4 , the PMMA system can be endowed with the same amount of incident light absorption in the 425-1025nm spectral band, with excellent Neutral filtering effect, can be widely used in the preparation of optical products (such as optical filters, video cameras or digital cameras).

In comparative example 4, the transmittance in the band after 675nm is gradually higher, the transmittance fluctuates greatly, and has no neutral filter effect; conventional carbon black and aniline black are added in comparative examples 5 to 6, although the obtained PMMA resin The material is consistent with each embodiment, and it is also a black material, but the transmittance in the near-infrared band (750-1025nm) is gradually higher, resulting in large fluctuations in the transmittance; in Comparative Example 7, red, yellow, blue, and green inorganic metals are added Pigment composite coloring agent to obtain black PMMA resin material, although its transmittance curve is flat compared with comparative examples 5-6 with carbon black and aniline black, but the stability is not good, and the 425-1025nm band transmittance fluctuation exceeds 10%; , the amount of additives used in Comparative Example 8 is too large, the light transmittance in the 425-1025nm band is lower than 10%, the light absorption is too strong, it is pure black, and has no neutral filter effect. .
