Description
Technical field
The present invention relates to modified resin technical field, specifically, it relates to a kind of PC/ABS composition and its preparation method improving air-conditioning panel photoetch phenomenon.
Background technology
Instantly, the demand of air-conditioning product is broken through the limitation of product basic function by people already, and whether the profile of product is attractive in appearance, whether with domestic environment harmony, has become one of principal element of considering when people choose household electrical appliance. On the other hand, frequency conversion, the big technical development trend of energy-saving and environmental protection three lack support under current industry environment, and development is relatively slower, and the change of the product appearance that the fine setting of basic technology brings just is becoming a kind of irresistible trend. In this context, the concealed design of LED display is arisen at the historic moment, and becomes one of mainstay of air-conditioning panel instantly.
The concealed design of display screen is " stealthy formula " by the design of LED of air-conditioning panel, during off-position, cannot see the existence of display screen on panel, when after work, displaying contents above display screen machine just can be seen, panel is integral type, it is not necessary to reserve display screen windows. The concealed design of LED display makes product design more flexible, the overall artistic design of available protecting product design. LED is super, and big numerical monitor can be seen clearly without the need to walking close to, and greatly facilitates the use of human consumer.
ABS resin not only has toughness, hardness, rigidity excellent mechanical property balanced mutually, and has the performances such as good dimensional stability, surface gloss, low temperature tolerance characteristics, tinctorial property and processing fluidity. Excellent performance, extremely high cost performance make ABS resin become the only selection of air-conditioning panel. But ABS can produce photoetch effect under the irradiation of light source. After light source irradiation, in ABS material, the structure of the coloring matter of trace changes so that ABS resin color becomes white, if the color of material is more shallow, this kind turns white effect and will be easy to be found. This characteristic of ABS makes white color system ABS, PC/ABS materials application when the air-conditioning panel of the concealed design of display screen, and the field color irradiated through LED can occur significantly to become white, seriously affects the outward appearance of air-conditioning. At present, there is not yet the document report improving white ABS, PC/ABS photoetch phenomenon.
