- Comparative Example 1 since the glass fiber reinforced polycarbonate composition was not modified, and the traditional polycarbonate composition (PCABS material) was high gloss, a matte surface texture could not be achieved.
- the addition of the toughening agent cannot achieve a matte effect, but it brings the risk of processing defects and phase separation; in Comparative Example 3, because only acrylic shell silicone rubber was added, the matte effect could not be achieved through the addition amount; in Comparative Example 2, only the addition of Polyurethane, although it can reduce the gloss, does not meet the requirements of uniform matte, and adding polyurethane alone will cause the polycarbonate resin matrix to not have enough toughness, resulting in application limitations;
- Comparative Example 6 is due to the addition of acrylic shell silicone rubber rubber particles The diameter (D50) is too small, and the fluidity is further improved, which will easily lead to unstable extrusion; when subjected to external force, the thickness of the resin layer between the rubber particles is not enough to effectively prevent the crack from expanding, so the bending toughness is not good, and the phenomenon of fracture occurs; At the same time,
- Comparative Example 7 Because the diameter of the added glass fiber is too large, the effective surface roughness under the same amount of addition is difficult to exert the limiting effect on the rubber particles on the surface of the composition, and the distribution of the excessive glass fiber diameter in the matrix resin causes stress The transfer point is greatly reduced, so the flexural modulus decreases, the flexural toughness is broken, and the gloss cannot be effectively improved.

It is used in various fields, especially in the fields of electronic appliances, transportation, and building materials. With the development of the industry, the requirements for materials are also getting higher and higher. The modified polycarbonate and its alloys are reinforced by glass fibers, giving the material higher strength, rigidity, high temperature resistance and insulation properties. development trend. In addition to the high-performance development requirements for materials such as high rigidity and high modulus, it is also necessary to give materials a certain degree of visual perception, especially in the design of electrical and electronic product casings, the matte technology of materials can improve the use of materials. In the process, the visual comfort is improved, for example, on the housing of household appliances, the frame and the back shell of the PAD, etc., from the perspective of improving the visual comfort, the enhancement of the hand feel, and the convenience of post-processing, the appropriate matte effect should be considered. Glass fiber reinforced polycarbonate material is one of the key considerations for design optimization, so the development of glass fiber reinforced polycarbonate with matte effect has broad application prospects in different industries.
目前常用哑光技术有以下几种：At present, the commonly used matte technologies are as follows:
1)添加无机材料，如纳米二氧化硅，通过利用填料表面和基体树脂之间的不相容性和不易浸润性，在加工的过程中填料会迁移，形成凹凸不平的的表面，从而产生哑光效果；CN201410177444.2就公开通过添加ACS和纳米二氧化硅来实现哑光效果的PCABS。1) Add inorganic materials, such as nano-silica, by utilizing the incompatibility and infiltration between the filler surface and the matrix resin, the filler will migrate during processing to form an uneven surface, resulting in dumb Light effect; CN201410177444.2 discloses PCABS which realizes matte effect by adding ACS and nano-silica.
2)加入含量较高的橡胶，尤其是粒径较大或者具有一定交联度的橡胶，在加工过程中橡胶和树脂基体会发生分相，通过橡胶发生的微收缩导致材料表面形成粗糙的效果而产生哑光效果；2) When adding rubber with high content, especially rubber with larger particle size or a certain degree of cross-linking, the rubber and resin matrix will undergo phase separation during processing, and the micro-shrinkage of the rubber will cause the surface of the material to form a rough effect. resulting in a matte effect;
3)加入环氧类物质，通过环氧基团的引入，降低了ABS和PC树脂之间的相容性，从而降低材料表面的光泽度，从而产生哑光效果；CN201810442932.X就公开了通过添加环氧化物和云母粉来实现哑光效果的PCABS。3) Adding epoxy substances, through the introduction of epoxy groups, the compatibility between ABS and PC resins is reduced, thereby reducing the gloss of the material surface, thereby producing a matte effect; CN201810442932.X has disclosed that through Add epoxy and mica powder to achieve matte finish PCABS.
4)也可通过注塑模具的纹路设计，使材料表面具有一定的粗糙度，从而实现哑光效果。4) The surface of the material can also have a certain roughness through the pattern design of the injection mold, so as to achieve a matte effect.
以上的哑光技术均具有一定的局限性，如填料的加入会导致基体连续相的不一致，容易引起力学性能和外观等其它性能，尤其是加工过程中熔接线隐患；橡胶和环氧的大量加入会大幅度影响树脂的流动性，以及降低材料的刚性，因此在一定程度上限制了材料的应用，尤其是薄壁化的行业发展趋势下，较低的流动性将产生较大的弊端；依靠模具设计对材料的加工条件依赖性强，适用性不广。The above matte technologies all have certain limitations. For example, the addition of fillers will lead to inconsistencies in the continuous phase of the matrix, which may easily cause other properties such as mechanical properties and appearance, especially the hidden danger of weld lines during processing; a large number of rubber and epoxy are added. It will greatly affect the fluidity of the resin and reduce the rigidity of the material, so it limits the application of the material to a certain extent, especially in the thin-walled industry development trend, lower fluidity will produce greater drawbacks; relying on The mold design is strongly dependent on the processing conditions of the material, and the applicability is not wide.
因此，开发一种兼具哑光，弯折韧性，且易于加工的玻纤增强聚碳酸酯具有重要的研究意义和经济价值。Therefore, it is of great research significance and economic value to develop a glass fiber reinforced polycarbonate that has both matte finish, bending toughness, and easy processing.

表4 各实施例和对比例的玻纤增强聚碳酸酯组合物的性能测试结果Table 4 Performance test results of glass fiber reinforced polycarbonate compositions of each embodiment and comparative example
从表4可知，本发明各实施例提供的玻纤增强的聚碳酸酯具有较好的弯折韧性及优异的哑光性能。It can be seen from Table 4 that the glass fiber reinforced polycarbonate provided by each embodiment of the present invention has good bending toughness and excellent matte performance.
其中，玻纤的引入，除可实现材料的增强外，由于玻纤与树脂之间的的表面 张力存在一定的差异，材料的注塑光泽度会随着玻纤含量的增加而降低，同时弯曲模量增高，在一定范围内和丙烯酸酯类硅橡胶以及聚氨酯的哑光和韧性协同，实现较高的弯折韧性；随着玻纤含量的增加，弯曲模量也增加。Among them, the introduction of glass fiber, in addition to the enhancement of the material, due to the difference in the surface tension between the glass fiber and the resin, the injection gloss of the material will decrease with the increase of the glass fiber content, while the bending mold With the increase of the amount of glass fiber, it can cooperate with the matteness and toughness of acrylic silicone rubber and polyurethane within a certain range to achieve higher flexural toughness; with the increase of glass fiber content, the flexural modulus also increases.
丙烯酸壳类硅橡胶的加入可使得光泽度能呈现较为满意的哑光效果，但弯曲模量会稍微下降；具体地，在一定范围内(实施例1、6～9)，丙烯酸壳类硅橡胶的添加量增大时，弯折韧性得到较好的保障，而且注塑哑光效果越来越明显，挤出哑光效果维持满意水平；丙烯酸壳类硅橡胶的添加量继续增大时，哑光效果由于丙烯酸壳类硅橡胶和聚氨酯的协同作用减弱也略有降低；但丙烯酸壳类硅橡胶的添加量较大时，外观会出现缺陷隐患；如丙烯酸壳类硅橡胶的添加量过大(如对比例4)，会引起材料的严重分层外观缺陷，并且丙烯酸壳类硅橡胶中的橡胶粒子将析出至组合物的表面导致相分离，且使得哑光效果相对于不添加(对比例1)仅略有提升。The addition of acrylic shell silicone rubber can make the gloss show a satisfactory matte effect, but the flexural modulus will decrease slightly; When the addition amount of acrylic shell silicone rubber continues to increase, the bending toughness is better guaranteed, and the injection molding matte effect becomes more and more obvious, and the extrusion matte effect maintains a satisfactory level; when the addition amount of acrylic shell silicone rubber continues to increase, the matte finish The effect is also slightly reduced due to the weakening of the synergistic effect of acrylic shell silicone rubber and polyurethane; however, when the addition amount of acrylic shell silicone rubber is large, there will be hidden defects in appearance; if the addition amount of acrylic shell silicone rubber is too large (such as Comparative example 4), will cause serious delamination appearance defects of the material, and the rubber particles in the acrylic shell silicone rubber will precipitate to the surface of the composition resulting in phase separation, and make the matte effect relative to no addition (Comparative example 1) Only slightly improved.
聚氨酯的加入可改善韧性和光泽效果。在一定范围内(实施例1、10～13)，聚氨酯的添加量增大时，哑光效果越来越好，尤其是挤出哑光改善，弯折韧性也增强；但聚氨酯的添加量较大时，哑光效果由于丙烯酸壳类硅橡胶和聚氨酯的协同作用减弱也略有降低，且体系的热稳定性降低将导致弯折韧性的下降；如聚氨酯的添加量过大(如对比例5)，会严重降低体系的热稳定性导致弯折韧性的下降，进而出现折断现象；当丙烯酸壳类硅橡胶的添加量为5～10，聚氨酯的添加量为5～10时，具有更佳的综合性能。而对比例1由于未对玻纤增强的聚碳酸酯组合物进行改性处理，和传统的聚碳酸酯组合物(PCABS材料)都为高光泽，无法实现哑光的表面质感，通过单一的增韧剂的加入不能实现哑光效果，却带来加工缺陷和相分离的风险；对比例3由于仅添加丙烯酸壳类硅橡胶，无法通过添加量实现哑光效果的呈现；对比例2由于仅添加聚氨酯，虽然可以降低光泽度但是不满足均匀的哑光要求，同时单独加入聚氨酯会导致聚碳酸酯树脂基体不具备足够的韧性导致应用局限；对比例6由于添加的丙烯酸壳类硅橡胶的橡胶粒径(D50)过小，流动性得到进一步提升易引起挤出不稳定；在受到外力作用时，橡胶粒间的树脂层厚度不足以有效阻止裂纹扩展，因此弯折韧性不佳，出现折断现象；同时玻纤增强的聚碳酸酯组合物无法形成足够的表面质量的橡胶粒子来达到一定的漫反射效果，对光泽的改善效果不佳。对比例7由于添加的玻璃纤维的 直径过大，在同等添加量下有效的表面粗糙度对组合物表面的橡胶粒子的限制作用难以发挥，同时玻纤直径过大在基体树脂中的分布造成应力传递点大大降低，故弯曲模量下降，弯曲韧性差出现折断，光泽度也无法得到有效提升。The addition of polyurethane can improve toughness and gloss effect. Within a certain range (Examples 1, 10-13), when the addition amount of polyurethane increases, the matte effect is getting better and better, especially the extrusion matte is improved, and the bending toughness is also enhanced; but the addition amount of polyurethane is relatively When it is large, the matte effect is also slightly reduced due to the weakening of the synergistic effect of acrylic shell silicone rubber and polyurethane, and the reduction of the thermal stability of the system will lead to a decrease in bending toughness; if the amount of polyurethane added is too large (such as Comparative Example 5 ), it will seriously reduce the thermal stability of the system, resulting in a decrease in bending toughness and a fracture phenomenon; when the addition of acrylic shell silicone rubber is 5-10, and the addition of polyurethane is 5-10, it has better performance comprehensive performance. In Comparative Example 1, since the glass fiber reinforced polycarbonate composition was not modified, and the traditional polycarbonate composition (PCABS material) was high gloss, a matte surface texture could not be achieved. The addition of the toughening agent cannot achieve a matte effect, but it brings the risk of processing defects and phase separation; in Comparative Example 3, because only acrylic shell silicone rubber was added, the matte effect could not be achieved through the addition amount; in Comparative Example 2, only the addition of Polyurethane, although it can reduce the gloss, does not meet the requirements of uniform matte, and adding polyurethane alone will cause the polycarbonate resin matrix to not have enough toughness, resulting in application limitations; Comparative Example 6 is due to the addition of acrylic shell silicone rubber rubber particles The diameter (D50) is too small, and the fluidity is further improved, which will easily lead to unstable extrusion; when subjected to external force, the thickness of the resin layer between the rubber particles is not enough to effectively prevent the crack from expanding, so the bending toughness is not good, and the phenomenon of fracture occurs; At the same time, the glass fiber reinforced polycarbonate composition cannot form rubber particles with sufficient surface quality to achieve a certain diffuse reflection effect, and the effect of improving gloss is not good. Comparative Example 7 Because the diameter of the added glass fiber is too large, the effective surface roughness under the same amount of addition is difficult to exert the limiting effect on the rubber particles on the surface of the composition, and the distribution of the excessive glass fiber diameter in the matrix resin causes stress The transfer point is greatly reduced, so the flexural modulus decreases, the flexural toughness is broken, and the gloss cannot be effectively improved.
