Abstract
The invention discloses a novel pearly-luster ABS material. The novel pearly-luster ABS material is prepared from, by weight, 70-85% of ABS resin, 5-10% of pearlescent pigment particles, 5-10% of compatilizer, 0.5-1% of lubricant, 0.2-0.5% of antioxidant and 3-5% of flexibilizer. The components are evenly mixed in a high-speed mixer and a low-speed mixer, and are molten through a single screw extruder for extrusion and granulation. The pearly-luster ABS material produced through the processing method has a good pearly luster effect, and the mechanical performance is greatly improved compared with the prior art.
Description
Technical field
The present invention relates to polymeric material field, especially a kind of novel macreous ABS material and working method.
Background technology
Along with the sustainable development of household electrical appliance and the continuous change of people's aesthetic conceptions, the plastic cement material appliance shell with pearl effect is subject to the popular welcome of people.At present mainly through reaching pearl effect with under type, with ABS (propylene is fine, vinylbenzene, butadienecopolymer) for base material, add a certain proportion of pearly pigment through the blended granulation of twin screw, then be injection molded into appliance shell with the particulate material that blended granulation is produced.Its pearly pigment main component of adding is at the coated layer of metal oxide compound of the mica surface of sheet, changes the particle diameter of metal oxide and pearly pigment, can reach different pearl effects.But due to pearly pigment and ABS resin consistency poor, after blended with ABS resin, not only difficulty obtains good pearl effect, and comparatively large to ABS resin Effect on Mechanical Properties, need be long and shear stronger twin screw and carry out blended granulation processing with major diameter.
Following defect is obviously there is when current ABS and the blended granulation of pearly pigment:
1, pearly pigment and ABS resin poor compatibility, not only affects ABS material physicals, more also there will be pearly pigment dispersion bad caused macroscopic irregularity during injection moulding massive article because consistency is bad, is commonly called as material flower.
2, existing working method can reduce pearly pigment particle diameter, reduces pearl effect.Due to pearly pigment and ABS substrate consistency poor, existing mode is through the blended granulation of major diameter long (being greater than 40) twin screw extruder after ABS mixes with pearly pigment, and it is comparatively large that this kind of method shears dynamics, and then destroy larger to pearly pigment.Pearly pigment particle diameter is diminished, and then finished product pearl effect is deteriorated.
3, finished product machinery poor-performing.Feel when client uses ' embrittlement ' below two kinds of modes to cause ABS mechanical property to decline larger: A, pearly pigment and ABS poor compatibility, add a certain proportion of pearly pigment larger to ABS performance impact; The long twin screw of B, major diameter is sheared comparatively strong, destroys larger to ABS performance.
Summary of the invention
The present invention proposes a kind of novel macreous ABS material and working method, by the pre-treatment to pearly pigment, the consistency of pearly pigment and ABS resin can be improved, make the pearly-lustre ABS material of production have stronger pearl effect and physical strength.
Technical scheme of the present invention is achieved in that
