Abstract

The invention discloses a hollow glass bead filling-modified acrylonitrile-butadiene-styrene (ABS) material and a preparation method thereof. The hollow glass bead filling-modified ABS material comprises: by weight, 50 to 80% of ABS resin, 3 to 5% of a compatilizer, 5 to 10% of a flexibilizer, 3 to 5% of a coupling agent, 1 to 3% of a reinforcing agent, 5 to 30% of hollow glass beads, and 1 to 3% of plastic processing assistants. The ABS resin as a base resin, the hollow glass beads as filling materials, and appropriate types and proportions of the assistants are prepared into the hollow glass bead filling-modified ABS material under appropriate technical conditions and thus the hollow glass bead filling-modified ABS material has a low cost and excellent tensile strength, bending strength, a bending modulus, impact strength and liquidity indexes, and can be widely used for instruments, household appliances, toys, entertainment products and a construction industry.

Description

[technical field] [0001] The invention relates to the technical field of polymer materials, in particular to a modified ABS material filled with hollow glass microspheres and a preparation method thereof. [Background technique] [0002] ABS resin is modified from polystyrene and butadiene. It is one of the cheapest engineering plastics. It is easy to process, has excellent dimensional stability, higher impact strength than PS, higher rigidity, and excellent dielectric insulation. Good resistance, good gloss, easy to paint, low water absorption. [0003] Hollow glass microspheres are composed of inorganic materials, including silica, alumina, zirconia, magnesia and sodium silicate according to their chemical composition. Its particle size is ten to several hundred microns, and its wall thickness is several microns. It is a closed microsphere filled with carbon dioxide and other gases. And it has the advantages of light weight, low thermal conductivity, non-toxic, non-combus...
