pmma/ABS合金的耐候性
众所周知，由于ABS中存在不饱和双键，其产品耐候性较差。尤其是浅色产品在使用和放置期间容易变黄和变白，这会影响产品的外观，并导致机械性能显著降低。材料悄然失去使用价值。为了提高ABS的耐候性，通常的方法是添加耐候剂，但随着光照时间的增加，成本会显著增加，耐候性的提高受到限制。通过制备PMMAIABS合金，材料的耐候性显著提高。天然ABS/PMMA合金的风化曲线。当PMMA添加量为20%时，材料的4E降低68%，并随着PMMA含量的增加而逐渐降低。然而，应该注意的是，PMMA熔体的粘度相对较大，韧性相对较低。PMMA与耐候剂的复配可以在较低的PMMA添加量下获得更好的耐候性，并保持材料的加工和使用性能
与PCIABS相比，PMMAJABS具有无可比拟的耐候性优势。在相同的试验条件下，PMMA含量为50%的PMMAABS合金的浅色色差约为ABS的1/30和PCIABS的1/4，使得PMMAIABS平台金特别适用于要求高耐候性的浅色产品，如户外工厂广告牌、荧光标志等，可以长时间保持优异的外观效果

Weather resistance of PMMA/ABS alloy
As we all know, due to the presence of unsaturated double bonds in ABS, its products have poor weather resistance. Especially light-colored products are prone to yellowing and whitening during use and placement, which affects the appearance of the product, and causes a significant decrease in mechanical properties. Material loses use price quietly. In order to improve the weather resistance of ABS, the usual method is to add weathering agents, but the cost will increase significantly and the improvement of weather resistance is limited with the increase of light time. By preparing PMMAIABS alloy, the weather resistance of the material is significantly improved. The weathering curve of natural ABS/PMMA alloy. When PMMA is added 20%, the 4E of the material decreases by 68%, and gradually decreases with the increase of PMMA content. However, it should be noted that the viscosity of PMMA melt is relatively large and the toughness is relatively low. The compounding of PMMA and weathering agent can achieve better weather resistance at low PMMA addition and maintain the processing and use performance of the material.
Compared with PCIABS, PMMAJABS has incomparable weather resistance advantages. Under the same test conditions, PMMAABS alloy with PMMA content of 50% has a light color difference of about 1/30 of ABS and 1/4 of PCIABS, making PMMAIABS platform Gold is particularly suitable for light-colored products that require high weather resistance, such as outdoor factory billboards, fluorescent signs, etc., which can maintain excellent appearance effects for a long time.
