Body fadedness and mechanical performance retentivity, it is possible to increase the thermostability of Heat resistance ABS material and mechanical performance.Meanwhile, 2-
(2 '-hydroxyl-3 ', 5 '-di-tert-butyl-phenyl)-5-chlorinated benzotriazole is imitated with above-mentioned antioxidant and with having significantly to work in coordination with
Should, it is possible to be effectively improved the thermo-oxidative stability of Heat resistance ABS material.Ultraviolet absorber can select such as BASF to produce
UV327, can directly buy from market.
Generally, during to ABS resin modification, bad i.e. can the causing in material of material plasticizing effect has little particle shape to occur,
Once these little granules of injection mo(u)lding will form pit.Ethylene bis stearamide and 2-(2 '-hydroxyl-3 ', 5 '-two tertiary fourths
Base phenyl)-5-chlorinated benzotriazole all can have preferable cooperative effect and the compatibility with above-mentioned heat-resistant agent, antioxidant,
Thus avoid producing pit in ABS resin modifying process.
The preparation method of a kind of Heat resistance ABS material that the embodiment of the present invention provides, comprising:
According to the mass fraction, by the ABS resin of 80～95 parts, the high glue powder of 0～10 part, the heat-resistant agent of 2～15 parts, 0.3
～auxiliary agent mixing, extrusion and the pelletize of the antioxidant of 0.9 part and 0.5～1 part, obtain Heat resistance ABS material.Wherein, auxiliary agent
Including lubricant and ultraviolet absorber.
Specifically, above-mentioned ABS resin, high glue powder, heat-resistant agent, antioxidant and auxiliary agent are joined mixing in mixer equal
Even.Mixer can select high speed mixer.Screw extruder can select double screw extruder, the screw rod of double screw extruder
It is divided into feed zone, compression section, fluxing zone and homogenizing zone.Feed zone is the leading portion of screw rod, near the feeding of double screw extruder
Mouthful, the effect of this section is material to act primarily as heat transfer soften, carry.Compression section is the stage casing of screw rod, and the effect of this section is to thing
Material continues heating, softens and melted.Fluxing zone is the part between terminal and the rear of screw rod, and the effect of this section is to melted
Material plastify completely.Homogenizing zone is the rear of screw rod, and near the die orifice of double screw extruder, the effect of this section is to mould completely
The material stirring changed uniformly becomes the melt of uniform quality and extruded.
Stagger arrangement angle refers to the angle of adjacent two panels kneading block symmetrical center line.It is generally divided into 30 °, 45 °, 90 °.On making
State material to reach preferably plastify and melt effect during extruding pelletization, dropped by the selection at kneading block stagger arrangement angle
The weak shearing of the low screw rod shear strength to material, i.e. screw combinations, to prevent material from dropping during extruding pelletization
Solve.The screw combinations of use double screw extruder is: the stagger arrangement angle of fluxing zone kneading block is 30 ° or 45 °, homogenizing zone kneading block
Stagger arrangement angle is 30 ° or 45 °.
Owing to the viscosity of sizing material is higher, Extrusion can produce under the effect of shearing force substantial amounts of heat.Pass through
Controlling twin screw draw ratio is 40:1, it is possible within making the rising of temperature be maintained at certain limit.To avoid material at double spiral shells
Decompose in bar extruder.
The above-mentioned material mixed is joined in double screw extruder, the temperature of setting double screw extruder: feed zone
Temperature is 190～200 DEG C, and compression section temperature is 195～200 DEG C, and fluxing zone temperature is 215～230 DEG C, and homogenizing zone temperature is
210～225 DEG C, die temperature is 205～220 DEG C.Mixed material passes sequentially through feed zone, compression section, fluxing zone, homogenizing
Section, die orifice/die head, complete extrusion and pelletize, obtain Heat resistance ABS material.
The Heat resistance ABS material prepared by said temperature control and screw combinations is had and has more preferably than common ABS
Thermostability, it is possible to the field that cannot meet for common ABS heat resistance, such as manufacture automobile lamp time, lamp material is 90
～it being sprayed at Heat resistance ABS material by baking finish process under the conditions of 100 DEG C, the thermostability of the Heat resistance ABS material of the present invention can reach
To using requirement.Simultaneously, it is to avoid make automobile component and the problem of pit occurs, shades of colour can be made into again and meet automotive trim
All kinds of color requirements.
