PC/ABS的耐候性
产品详细信息PC/ABS的耐候性由于ABS中的丁二烯组分含有双键，在长期光照条件下很容易破坏分子键，当PCIABS用于浅色和户外产品时，存在变色风险，从而影响产品的外观。耐候PC/ABS，主要用于车灯、电脑外壳、手机外壳等。
由于ABS中的丁烯成分含有双键，在长期光照条件下很容易破坏分子键。PC/ABS在户外使用时可能会变色，这将影响产品的外观
以下方案通常用于提高材料的耐候性
<1>添加耐候剂。添加时应考虑与基材的匹配。应尽可能避免使用组胺光稳定剂。大多数组胺光稳定剂是弱碱性物质，容易降解PC，导致材料性能恶化
<2>增加碳粉浓度，并尽可能避免使用荧光增白剂0B。如果金红石型二氧化钛能屏蔽紫外线，不易变色；炭黑吸收紫外线J.
荧光增白剂，通常通过300-400mm的紫外吸收波长，可在500nm下发出蓝色或蓝紫光，达到产品增白增白效果，在长期使用过程中易使分子活化，导致分子链断裂，呈黄色，易碎，对使用中的白色产品的耐候性有更高的要求

Weather Resistance Of PC/ABS
Product Details
Weather resistance of PC/ABS
As the butadiene component in ABS contains double bonds, it is easy to break molecular bonds under long-term light conditions, and there is a risk of discoloration when PCIABS is used in light color and outdoor products, which affects the products
View. Weather resistant PC/ABS, mainly used for car lights, computer housing, mobile phone housing, etc.
As the butene component in ABS contains double bonds, it is easy to break molecular bonds under long-term light conditions. PC/ABS may be at risk of discoloration when used outdoors, which will affect the appearance of the product.
The following schemes are commonly used to improve the weather resistance of materials
Weather resistance of PC/ABS:
<1> add weather resistant agent. The match with the base material should be considered when adding. The use of histamine light stabilizers should be avoided as much as possible. Most histamine light stabilizers are weak base substances, which are easy to degrade PC, resulting in the deterioration of material performance.
<2> increases toner concentration and avoids the use of fluorescent brightener 0B as far as possible. If rutile type titanium dioxide can shield uv, not easy to change color; Carbon black absorbs ULTRAVIOLET light J.
Fluorescent whitening agent, usually through uv absorption wavelength of 300 to 400 mm, can emit blue or LanZiGuang under 500 nm to achieve products whitening and brightening effect, easy to make in the process of long-term use of molecular activation, lead to molecular chain rupture, showing it is yellow, brittle, higher requirements on weather resistance of white products in use.
