Abstract
The invention relates to a special aluminium pigment for plastics and a preparation method thereof, wherein the special aluminium pigment for the plastics is prepared by mixing the following components in proportion by weight: 80 to 90 parts by weight of aluminium powder, 8 to 12 parts by weight of gas phase silicon dioxide and 3 to 8 parts by weight of polyethlene wax. The special aluminium pigment for the plastics has good dispersive property in the plastics, so that the injection molding process is more fluent and finer, and the surface of an injection molding part is smoother, brighter and cleaner.
Description
Technical field
The present invention relates to a kind of pigment and manufacture method thereof, especially relate to a kind of special aluminium pigment for plastics and manufacture method thereof.
Background technology
Existing all kinds of plastic cement pigment dispersed relatively poor in plastic cement has detrimentally affect to the quality of moulding, and can make moulding be difficult for the demoulding, and die life is also had negative impact.
Summary of the invention
The objective of the invention is to overcome the defective that existing plastic cement pigment exists, a kind of good dispersity is provided, the quality of moulding is not had detrimentally affect, and can prolong the special aluminium pigment for plastics and the manufacture method thereof of die life.
The present invention's special aluminium pigment for plastics is mixed by following component and weight proportion and forms: aluminium powder 80-90 weight part, aerosil 8-12 weight part, polyethylene wax 3-8 weight part; Optimum ratio is: aluminium powder 84-86 weight part, aerosil 9-11 weight part, polyethylene wax 4-6 weight part; More preferably proportioning: aluminium powder 85 weight parts, aerosil 10 weight parts, polyethylene wax 5 weight parts.
The granularity of aluminium powder is decided on user's needs, generally can be at D
50Select between=5-30 the micron.
The manufacture method of the present invention's special aluminium pigment for plastics comprises the steps: that (1) is mixed: that will select adds the formulated aluminium paste (there is sale in market) of organic solvent (described organic solvent generally is low boiling point organic solvent such as methyl propionate or vinyl acetic monomer) by aluminium powder and places in the kneader, in kneader, add aerosil, polyethylene wax again, be heated to 50-60 ℃, stirred 50-70 minute, and made it to mix; (2) oven dry, remove organic solvent: the pulpous state aluminium pigment that stirs is taken out, place vacuum drying oven, be heated to 115-125 ℃, vacuumizing and drying makes organic solvent wherein evaporate into content≤1wt%; (3) moulding: the aluminium pigment that will dry places the extrusion device moulding, makes it to become the shape (preferably strip as Masterbatch, uses when being convenient to injection moulding) that needs.
Contained organic solvent is a kind of detrimental impurity in the aluminium pigment, and content is few more good more, can not surpass 1 wt% (still not having effective way at present removes it in plastic cement aluminium pigment fully) at most.
Studies show that, described aerosil can be high temperature resistant, trickle (the Φ＜1um) of particle, when high-temperature injection, these characteristics can not change, thereby can play beyond thought dissemination, can make the aluminum particle in the aluminium pigment in plastic cement (injection moulding), disperse more evenly, make injection moulding process more smooth, the moulding surface is more smooth, improves the quality of moulding; And can make the easy demoulding of moulding, mould is played a protective role, prolong die life.
The present invention uses polyethylene wax to make lubricant and auxiliary dispersants, can guarantee the surperficial moist of moulding, can also make plastic cement pigment be easy to be shaped the aluminium pigment of the different shape that obtains wanting; Also help improving the dispersiveness of aluminum particle in plastic cement in the aluminium pigment, make injection moulding process finer and smoother.
In a word, the present invention's special aluminium pigment for plastics has good dispersiveness in plastic cement, can make injection moulding process more smooth, finer and smoother, and the moulding surface is more smooth, brighter and cleaner; Also can prolong die life.
