Description

A kind of compositional flame-retardant strengthens plastic cement aluminum pigment
Technical field
The present invention relates to pigment technology field, particularly relate to a kind of compositional flame-retardant and strengthen plastic cement aluminum pigment.
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 application One of most metallic effect pigments.Aluminum pigment possesses good antiseptic property, moreover it is possible to reflection visible ray, has argenteous gold Belong to gloss, 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 coating and rubber and ageing of plastics Effect.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 converts For out and out action.Along with material and the development of mould process, exempt to spray the new trend becoming modified plastics development, resin Directly it is molded into part and can meet the effect that the manufacturers such as dumb light, high light or flaring pearlescent require.Eliminate and spray paint Technique, just eliminates the injury to environment, and greatly reduces manufacturing cost.Household electrical appliances, automobile, electronic product industry working of plastics Application complete, along with level of consumption and the raising of price, at household electrical appliances product profit drastically generally by workman is manual While reduction, 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 environment Pollute, improve product appearance class, reduce product cost, improve product competitiveness.So preparation is directly used in resin injection Aluminum pigment is particularly important, and the application in plastic industry of the aluminum pigment is increasingly praised highly.
In patent " a kind of strip aluminum pigment and preparation method thereof " by conventional aluminium pigment is carried out filter pressing then with High molecular polymer and auxiliary agent are extruded, and obtain the aluminum pigment of strip, and obtained aluminum pigment the most easily disperses, without powder Dirt, versatility is good, can greatly reduce current mark during plastic shaping, solves aluminum pigment bad scattered difficult problem in resin, but Resin and aluminum pigment and auxiliary agent are that during owing to extruding or being molded, temperature is all through high temperature melting twin screw again or Single screw extrusion Higher, the easy variable color of aluminum pigment or oxidation under high temperature, so that surface of the work metallochrome is dimmed, this is accomplished by being improved by modification The heat stability of aluminium powder, reduces 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 a kind of compositional flame-retardant strengthens plastic cement aluminum face Material.
The present invention is achieved by the following technical solutions:
A kind of compositional flame-retardant strengthens plastic cement aluminum pigment, is prepared by the raw materials in: flake aluminum 70-75, methyl-prop Alkene acryloxypropylethoxysilane trimethoxy silane 14-15, dehydrated alcohol are appropriate, trimethylolpropane trimethacrylate 28-30, acrylic acid 1-1-1.2, azodiisobutyronitrile 0.09-0.1, polyvinylpyrrolidone 1.75-1.9, fatty acid amide 3.5-4, polypropylene 18- 20, double (ethyl acetoacetate) metatitanic acid diisopropyl ester 2-3, APP 5-6, tetramethylolmethane 2-2.4, tetraethyl orthosilicate 1- 1.3, deionized water 5-6, TX-100.2-0.22, acetone in proper.
Described a kind of compositional flame-retardant strengthens plastic cement aluminum pigment, is made up of step in detail below:
2, a kind of compositional flame-retardant strengthens plastic cement aluminum pigment according to claim 1, it is characterised in that by step in detail below Make:
(1) by the dehydrated alcohol of molten for methacryloxypropyl trimethoxy silane 4-5 times amount, it is subsequently adding flaky aluminum Powder, is heated to 55-60 DEG C, and after reacting 1-1.5 hour with absolute ethanol washing for several times, vacuum drying obtains coupling modifier aluminium powder；
(2) by coupling modifier aluminium powder adds the dehydrated alcohol of 2-3 times amount, put in reactor, add three hydroxyl first while stirring Base propane triacrylate, acrylic acid and be dissolved in the polyvinylpyrrolidone of equivalent dehydrated alcohol, be heated under nitrogen protection 70-80 DEG C, then constant temperature dropping azodiisobutyronitrile, then rise to 85 DEG C and react 30-40 minute, question response is further continued for after terminating Stir 50-60 minute, natural cooling, centrifugation, obtain filter cake, finally filter cake is put into rotary evaporator evaporates anhydrous Ethanol, obtains being grafted aluminium powder；
(3) acetone of tetramethylolmethane with 2-3 times amount is mixed, add TX-10, tetraethyl orthosilicate, be sufficiently stirred for rear Under Ultrasonic Vibration Swing 30-40 minute, be subsequently adding deionized water, be heated to being cooled to room temperature, mistake after 40-50 DEG C of water bath with thermostatic control is reacted 2-3 hour Filter, with washing with acetone filter cake 2-3 time, finally vacuum drying at 60-70 DEG C, obtains Surface coating tetramethylolmethane stand-by；Will be poly- Propylene is sent in banbury, adds Surface coating tetramethylolmethane, APP, is heated to 140-150 DEG C, with 100-120 rev/min Speed banburying 5-6 minute, discharging, broken, obtain fire-retardant reinforcing aids；
(4) the fire-retardant reinforcing aids that grafting aluminium powder step (2) obtained obtains with step (3) mixes, and continuously adds its surplus Remaining composition, puts into extruded shape growth 3-5mm, the cylinder of a diameter of 1-2mm in double screw extruder, controls extrusion temperature and is 90-120 DEG C, finally it is 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 to flake aluminum Carry out coupling so that flake aluminum surface conversion is lipophile, be allowed to preferably mix with oiliness monomer, in order at particle surface Carry out home position polymerization reaction, be then polymerized by in-situ solution and trimethylolpropane trimethacrylate is coated on flake aluminum table Face, clad is uniform and thin, serves the effect increasing interparticle repulsive forces, is equivalent to the effect of dispersant, improves aluminium powder Dispersive property, simultaneously can intercept aluminium powder and directly contact with air, moisture, further increase the decay resistance of aluminium powder with And the activity of holding aluminium powder, the aluminium powder heat stability after cladding is greatly improved simultaneously.
The present invention carries out banburying, as auxiliary agent by compounding to the tetramethylolmethane of surface coating modification and APP with polypropylene Adding in the preparation of aluminum pigment, synergism enables to flame-retardant composition and distributes uniformly in aluminum pigment, the energy when burning The layer of charcoal that enough formation is more stable, flame retardant effect is notable, and product of the present invention is good with the COMPONENTS COMPATIBILITY such as plastics, rubber, dispersibility Can be good, fire prevention, environmental protection, safety coefficient is high, and technique is simply easy to commercial production.
