Abstract
The invention provides a kind of used as television highlight antiflaming and strengthen PC/ABS compositions, be made up of the raw material including following weight portion: PC 40 80 parts, surface modification agent 5 25 parts, glass fibre 5 25 parts, 5 45 parts of ABS anti-impact modifier one step material；Wherein, described ABS anti-impact modifier one step material is made up of the raw material including following weight portion: ABS 50 80 parts, anti-impact modifier 20 50 parts.Used as television highlight antiflaming of the present invention strengthens the PC/ABS compositions extrusion by ABS anti-impact modifier one step material, owing to aqueous water at high temperature volatilizees, dissolve and take the small-molecule substance in ABS and anti-impact modifier out of, coordinate the effect of double vacuum simultaneously, effectively take volatile matter out of barrel, production obtains ABS anti-impact modifier one step material, has produced to dry and re-uses.
Description
Technical field
The invention belongs to macromolecule modified technical field, especially relate to a kind of used as television highlight antiflaming and strengthen PC/ABS
Compositions.
Background technology
Merlon (PC) is a kind of thermoplastic engineering plastic with desirable physical mechanical performance, and it is transparent and fire-retardant
Property is excellent, simultaneously because it is amorphous material, and its excellent in dimensional stability, it is widely used in a lot of fields；But by
Big in Merlon strand rigidity, melt viscosity is high, is easily generated stress cracking, and solvent resistance is poor, meets water and easily decompose under high temperature
Etc. shortcoming, limit its range to a certain extent.General by modification technology, pass through acrylonitrile-butadiene-styrene (ABS)
The addition of graft copolymer (ABS) improves its processability and internal stress, adds impact improving agent and improves Merlon group further
The toughness of compound.But due to ABS and impact improving agent synthesis time, dispersant or other auxiliary agents can be introduced, make fire retardation PC/
After ABS compositions, being easily generated small-molecule substance and separate out during injection, these little molecules may cause the disconnected of PC strand simultaneously
Split, thus bring great hidden danger to the performance of product and outward appearance.
Summary of the invention
In view of this, it is contemplated that propose a kind of used as television highlight antiflaming to strengthen PC/ABS compositions, ABS-is passed through
The production of anti-impact modifier one step material, by itself and surface modification agent, the collocation of PC, can effectively solve ABS and shock resistance
The problems such as spray that modifying agent small molecular material causes and film dirt, the addition of matching surface improving agent simultaneously can be effectively improved resistance
Combustion strengthens the outward appearance of PC/ABS material, improves other performances of material simultaneously.
