Description

A kind of black high-brightness ABS composition and method of making the same

Technical field

The present invention relates to ABS technical field, particularly, relate to a kind of black high-brightness ABS composition and method of making the same.

Background technology

ABS resin is a kind of high strength, good toughness, the thermoplastic macromolecule material of thermotolerance, lower temperature resistance, chemical proofing and excellent electrical properties, act normally the environment of-25 DEG C ~ 60 DEG C are little, and having good formability, the product size processed is stablized, and surface smoothness is high, be easy to application, dyeing and plating, be thus widely used in technical fields such as being applied to household electrical appliances.

But ABS also exists some defects, as melt viscosity is high, poor fluidity, thermostability and weathering resistance are not good.PMMA is a kind of good in optical property, has excellent weather resistance, and physical strength is good, has high transparency, and transmissivity is up to 91%-93%, but the shock strength of PMMA is not high, especially to notch sensitive.ABS and PMMA is carried out melt blending, the ABS/PMMA alloy of preparation can the advantage of comprehensive two kinds of plastics, make up respective shortcoming, the invention solves the compatibility problem of ABS/PMMA alloy material, increase high gloss and the scratch resistance of ABS/PMMA alloy material simultaneously, obtain there is high gloss, exempt to spray paint, the alloy material of scrape resistant, and make material have good mechanical property, thus achieve white goods housing high gloss, scrape resistant, exempt from sprayingization.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of black high-brightness ABS composition and method of making the same, described black high-brightness ABS composition luminance brightness is high, and glossiness is good, is convenient to shaping, without aerosol.

Technical scheme of the present invention is as follows: a kind of black high-brightness ABS composition, comprises each component that mass percentage is following:

Described black high-brightness ABS composition, comprises each component that mass percentage is following:

Described ABS is be the mass polymerization ABS resin of 50-80 according to ASTM D523 standard 60 ° of incident angle glossiness.

Described ABS is PA758.

The preparation method of described black high-brightness ABS composition, comprises the steps:

1) ABS and PMMA is added stirrer first to stir, then add ethylene bis stearamide, and toner 2N is blue, 3G is yellow, and EG is red and HBL purple, stirs 5-15 minute, obtain mixture in stirring stirrer according to 30-50rpm;

2) mixture is dropped in twin screw extruder, after melting, extrude, granulation, in whole process, the temperature of twin screw is divided into 9 sections, and each section of temperature is followed successively by 190 ± 15 DEG C, 195 ± 15 DEG C, 200 ± 15 DEG C, 200 ± 15 DEG C, 205 ± 15 DEG C, 205 ± 15 DEG C, 210 ± 15 DEG C, 210 ± 15 DEG C, 215 ± 15 DEG C.

Major ingredient of the present invention is ABS and PMMA.PMMA is commonly called as synthetic glass, has excellent optical property and photooxidation aging property, but its melt viscosity is large, and mobility is poor, and its notched Izod impact strength is very little.ABS and PMMA is carried out blended, resistance toheat and the mechanical property of ABS can be improved on the one hand; The mechanical property that can improve PMMA on the other hand particularly lacks M shock strength.When PMMA content reaches 40%, the tensile strength that the surface smoothness of ABS/PMMA alloy can bring up to 93%, ABS/PMMA alloy also significantly improves, but shock strength decreases.Result of study shows, ABS/PMMA mixture apparent melt viscosity raises gradually along with the increase of PMMA content in system.

Beneficial effect of the present invention is: the present invention, by ABS with PMMA is mixed, overcomes the opacity of ABS, has taken into account again the good transparency of PMMA simultaneously, products made thereby has good surface smoothness, pleasing appearance, shiny black, Gao Guang, be applicable to high light product, as printer casing, telephone outer shell and some automotive upholsteries, toy articles for use, building decoration bar, also can be used for electronic apparatus aspect, as the field such as instrument, high CD.
