Makrolon abbreviation PC, acrylonitrile-butadiene-styrene copolymer abbreviation ABS, the PC/ABS that the two is formed are compound
Material is a kind of important engineering plastics, can not only improve the heat resistance and tensile strength of ABS, moreover it is possible to reduce the melt viscosity of PC
So as to improve processing performance.
On the one hand, due to containing unsaturated double-bond in ABS structure so that the weatherability of PC/ABS composite materials is poor.Separately
On the one hand, phosphate ester flame retardants are often added in order to enhance the flame retardant property of PC/ABS composite materials, but the based flame retardant adds
Toughness of material can inevitably be reduced by adding;To ensure the toughness of PC/ABS composite materials, methyl methacrylate-fourth is often added
Styrene (MBS) can further decrease PC/ as toughener due to also containing unsaturated double-bond in MBS structures
The weatherability of ABS composite material.
In order to improve the weatherability of PC/ABS composite materials, need to add weather resisting agent.At present frequently with benzophenone purple
Ultraviolet absorbers, Benzotriazole Ultraviolet Stabilizer and triazine-based ultraviolet absorbent are as weather resisting agent.Though this kind of weather resisting agent
Weatherability can so be enhanced, but the weather resistance of made PC/ABS composite materials is limited, especially with prolonging for materials'use time
Long weatherability drastically declines.The addition of weather resisting agent must just be increased by wanting raising weather resistance and extension weatherability action time
Amount, and the increase of weather resisting agent additive amount can influence the toughness of material.
