Abstract
The invention discloses a composite material for computer shells. The composite material comprises the following components in parts by weight: 50-80 parts of PC, 5-20 parts of ABS, 15-25 parts of organic fibers, 5-25 parts of inorganicfibers, 5-10 parts of talcum powder, 1-8 parts of a flexibilizer, 0.5-2 parts of an antioxygen, 10-15 parts of a fire retardant and 0.1-0.3 part of toner. Through addition of organic fibers and inorganic fibers and on the basis that the mechanical performance of PC is not changed greatly, the composite materialhas the advantages that surface toughness is improved, application filed is widened and the application cost is lowered.
Description
Technical field
The present invention relates to a kind of matrix material of computer casing, belong to technical field of polymer materials.
Background technology
PC (polycarbonate) has excellent shock resistance, creep resistance, dimensional stability and electric insulating quality, a kind of engineering plastics of superior performance, be widely used in the fields such as mechanical means, computer equipment, automobile making, but also there is the shortcomings such as poor fluidity, easily stress cracking, easily aging and poor toughness, its application is in a lot of fields restricted.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to the defect overcoming prior art, a kind of matrix material of computer casing of activeness and quietness is provided.
In order to realize above-mentioned target, the present invention adopts following technical scheme: a kind of matrix material of computer casing, is characterized in that, comprises following component and the parts by weight of each component are:
PC 50-80 part;
