Description
Technical field
The invention belongs to modified plastics field, more particularly, to a kind of low-density, antistatic, wear-resisting enhancing PA6/PS materials
Material.
Background technology
Compared with other crystalline plastics such as polypropylene (PP), polyethylene (PE), styrene (PS) material has dimensionally stable
Property high, the features such as processing characteristics is good, and hygroscopicity is low.It is general material in household electrical appliances and OA Office Equipment Industries, it is domestic at present many
The housing of electrical equipment makes of PS materials extensively in more household electrical appliances producers, such as：Display, TV etc..But styrene materials intensity is general, to electricity
The shape and Functional Design of device housing are a kind of limitations.Meanwhile the heat resistance of PS materials is poor, this also greatly limit its product
The environment of application, it is impossible to which applying is having the product of heat resistant requirements.Nylon (PA6) material is a kind of common crystalline polymer,
Hydrogen bond action be present in its molecular structure, which dictates that it possesses excellent impact flexibility and good heat resistance.But it is inhaled
Water rate is larger, crystallization contraction causes poor dimensional stability.PA6/PS alloy materials combine the excellent properties of 2 kinds of materials, enhancing
PA6/PS alloy materials greatly improve the intensity of material, can apply in the product to material mechanical performance requirement.Mine
The instrument of upper operation first has to wear-resisting, is much that metal manufactures, but density metal is big, and instrument weight is very heavy, it is necessary to realize light
Quantify to substitute.Tool construction is complicated simultaneously, and material injection shaping needs the good processing characteristics of material.In addition, mine work
Environment dust is a lot, if material has anti-static dust-proof function with regard to more preferable.Can be same currently without a enhancing PA6/PS materials
When take into account low-density, permanent anti-static, this wear-resisting three aspects performance.
Chinese patent CN 103408928 discloses a kind of PA6/PS alloy materials of fiberglass reinforced, and this alloy material is close
Spend larger, and material does not possess anti-static function, and wear-resisting functions are also general.Chinese patent CN 103694695 discloses a kind of glass
Fibre enhancing halogen-free flameproof PA6/PS alloy materials, this alloy material add anti-flaming function, but still do not possess low-density, resist
Electrostatic, antiwear characteristic.
The content of the invention
In view of this, the present invention is directed to propose a kind of low-density, antistatic, wear-resisting enhancing PA6/PS materials, improve its boundary
Surface intensity, so as to improve the mechanical property of material.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of low-density, antistatic, wear-resisting enhancing PA6/PS materials, it is characterised in that：The material is by including following weight
