Description

A kind of aluminum pigment of PET covered composite yarn filler reinforced insulation performance
Technical field
The present invention relates to pigment technology field, particularly relate to the aluminum pigment of a kind of PET covered composite yarn filler reinforced insulation performance.
Background technology
Aluminum pigment is also known as aluminum paste, aluminum argentum powder, flake aluminum, and it has smooth and very thin sclay texture, is to apply one of most metallic effect pigments.Aluminum pigment possesses good antiseptic property, moreover it is possible to reflection visible ray, has argenteous metallic luster, is also changing, so aluminum pigment has good decorative effect along with the intensity of the light of the different reflections of angle simultaneously;Aluminum pigment also can reflect infrared light and ultraviolet light, thus also have heat-insulating property and delay the effect of coating and rubber and ageing of plastics.Along with country and the raising of social concerns degree, low-carbon (LC) is the most no longer a concept with the topic of environmental protection, but has been converted into out and out action.Along with material and the development of mould process, exempting to spray the new trend becoming modified plastics development, resin is directly molded into part can meet the effect that the manufacturers such as dumb light, high light or flaring pearlescent require.Eliminate the technique sprayed paint, just eliminate the injury to environment, and greatly reduce manufacturing cost.Household electrical appliances, automobile, the application of electronic product industry working of plastics complete by hand generally by workman, along with level of consumption and the raising of price, while household electrical appliances product profit drastically reduces, wage sharp rises, but the rising of recruitment cost has become enterprise and has been difficult to undertake the burden that must be born by again.Preparation has pearl effect, the plastic material of metal-like is directly used in the machine-shaping of household electrical appliances plastics appearance member and can reduce environmental pollution, improve product appearance class, reduce product cost, improves product competitiveness.So the aluminum pigment that preparation is directly used in resin injection is particularly important, the application in plastic industry of the aluminum pigment is increasingly praised highly.
Patent " a kind of strip aluminum pigment and preparation method thereof " is then extruded with high molecular polymer and auxiliary agent by conventional aluminium pigment is carried out filter pressing, obtain the aluminum pigment of strip, obtained aluminum pigment the most easily disperses, without dust, versatility is good, current mark can be greatly reduced during plastic shaping, solve aluminum pigment bad scattered difficult problem in resin, but resin is through high temperature melting twin screw again or Single screw extrusion with aluminum pigment and auxiliary agent, owing to when extrusion or injection, temperature is the highest, the easy variable color of aluminum pigment or oxidation under high temperature, so that surface of the work metallochrome is dimmed, this heat stability being accomplished by being improved aluminium powder by modification, reduce the corrosivity of aluminum pigment.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that the aluminum pigment of a kind of PET covered composite yarn filler reinforced insulation performance.
The present invention is achieved by the following technical solutions:
A kind of aluminum pigment of PET covered composite yarn filler reinforced insulation performance, it is prepared by the raw materials in: flake aluminum 70-75, methacryloxypropyl trimethoxy silane 14-15, dehydrated alcohol is appropriate, trimethylolpropane trimethacrylate 28-30, acrylic acid 1-1-1.2, azodiisobutyronitrile 0.09-0.1, polyvinylpyrrolidone 1.75-1.9, N, N ethylenebis ricinoleic acid amide 3-4, Low Density Polyethylene 17-19, Kaolin 2-3, distearyl thiodipropionate 1-1.2, alkylation nano silicon 3-4, deionized water 14-17, PET resin 2-3.
The aluminum pigment of described a kind of PET covered composite yarn filler reinforced insulation performance, is made up of step in detail below:
(1) by the dehydrated alcohol of molten for methacryloxypropyl trimethoxy silane 4-5 times amount, being subsequently adding flake aluminum, be heated to 55-60 DEG C, after reacting 1-1.5 hour with absolute ethanol washing for several times, vacuum drying obtains coupling modifier aluminium powder;
(2) coupling modifier aluminium powder will add the dehydrated alcohol of 2-3 times amount; put in reactor; add trimethylolpropane trimethacrylate, acrylic acid while stirring and be dissolved in the polyvinylpyrrolidone of equivalent dehydrated alcohol; it is heated to 70-80 DEG C under nitrogen protection; then constant temperature dropping azodiisobutyronitrile; then rise to 85 DEG C react 30-40 minute; question response is further continued for stirring 50-60 minute after terminating; natural cooling; centrifugation; obtain filter cake, finally filter cake is put into and rotary evaporator evaporates dehydrated alcohol, obtain being grafted aluminium powder;
(3) will add deionized water in alkylation nano silicon, stirring, to being uniformly dispersed, is subsequently adding Kaolin, ultrasonic disperse 30-40 minute, is then spray-dried, obtains mixed fillers;Mixed fillers is put in kneader, continuously add PET resin, distearyl thiodipropionate, being heated to 180-200 DEG C, mediate 15-20 minute, then discharging mixes with Low Density Polyethylene, put in mixing roll, it is heated to 90-100 DEG C, mixing 9-10 minute, discharging, broken, obtain PET covered composite yarn filler;
(4) the PET covered composite yarn filler that grafting aluminium powder step (2) obtained obtains with step (3) mixes, continuously add remaining residual components, put into extruded shape growth 3-5mm, the cylinder of a diameter of 1-2mm in double screw extruder, control extrusion temperature and be 90-120 DEG C, be finally vacuum dried 5-6 hour at 50-60 DEG C and get final product.
The invention have the advantage that the present invention first passes through methacryloxypropyl trimethoxy silane and flake aluminum is carried out coupling, making flake aluminum surface conversion is lipophile, it is allowed to preferably mix with oiliness monomer, to carry out home position polymerization reaction at particle surface, then it is polymerized by in-situ solution and trimethylolpropane trimethacrylate is coated on flake aluminum surface, clad is uniform and thin, serve the effect increasing interparticle repulsive forces, be equivalent to the effect of dispersant, improve the dispersive property of aluminium powder, aluminium powder and air can be intercepted simultaneously, moisture directly contacts, further increase the decay resistance of aluminium powder and keep the activity of aluminium powder, aluminium powder heat stability after cladding is greatly improved simultaneously.
Kaolin, alkylation nano silicon are obtained compounded mix by PET resin cladding by the present invention, add in the preparation of aluminum pigment, it is possible to increase the electrical insulation capability of product;Product of the present invention possesses good dispersibility, it is possible to be uniformly dispersed in plastic material, can manufacture the plastic parts that insulating requirements is high, has metallic luster, good stability of the dimension.
