Technical field
The invention belongs to technical field of polymer materials more particularly to a kind of high dispersive flame-proof ABS Masterbatch and its preparations
Method.
Background technology
ABS resin is the terpolymer of acrylonitrile, butadiene and styrene, its production method has blending method, is total at present
Poly- method and emulsion graft polymerization method three categories.By adjusting the proportioning of three kinds of monomers, can processability is different, the trade mark is different resin,
Such as high impact-resistant type, universal and special type.ABS is nontoxic, tasteless, has both tough, hard, rigid characteristic, is easy molding, comprehensive
Can be excellent, it is widely used in fields such as household electrical appliance, light industry stationery sports goods, auto industry and chemical industry.But it is to carry with ABS
When the Masterbatch of body is coloured, since carrier flow performance is poor, it is not easy to control to be susceptible to flow liner, uneven color, aberration
The problems such as.
Country's Masterbatch product structure is single at present, kind is not complete, and universal product accounts for very big proportion, and plastics need to colour
When coloured using monochromatic Masterbatch, need to add Anti-static electricity color master batch when antistatic property, addition resistance when needing flame retardant property
Fire Masterbatch.The method for adding single master batch to need to add when having high requirement to vector resin comprehensive performance
Thus the Masterbatch of a variety of different roles to consume a large amount of vector resin, and brings antioxidant in process to consume
The shortcomings of amount is high, downstream processing and forming component is more, complex process, following Masterbatch will be towards multifunction, high color content
It is continued to develop with the direction of high technology content.
With the improvement of living standards, pursuit itself living environment of people more is safe and healthy, clean comfortable, and pass through
It often appears in people at one's side, is in direct contact the plastic products of human body, the antibiotic property and anti-flammability of its own are to creating clean, peace
Full living environment plays an important role, and anti-microbial property is stronger, can more reduce disease incident, protects health；It is fire-retardant
Performance is stronger, can more reduce occurrence index, protects property safety and personal safety.For this purpose, the present invention is from plastic formula
Essential Masterbatch is set about, provide it is a kind of with high dispersive, fire-retardant, anti-microbial property ABS color master batch and its preparation side
Method.
Invention content
The present invention overcomes prior art deficiencies, provide a kind of high dispersive flame-proof ABS Masterbatch and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of high dispersive flame-proof ABS Masterbatch, is made of the raw material of following weight parts：
Polystyrene 40-60, inorganic pigment 20-30, composite dispersing agent 4-6, fiber 10-15, flame retardant of magnesium hydroxide 6-
9, filler material 0.1-1.

One kind in cobalt blue, iron oxide brown, chrome oxide green or arbitrary combination.
The composite dispersing agent be by dispersant YY -5023, maleic anhydride grafted polyethylene wax, titanate coupling agent by
Mass ratio is 2：2：1 ratio is formulated.
It is 2 in mass ratio that the fiber, which is by bamboo charcoal fiber and coconut palm Carbon fibe,：1 ratio composition.
The filler material is made of one or more in calcium carbonate, calcium stearate, barium sulfate.
A kind of high dispersive flame-proof ABS Masterbatch preparation method, includes the following steps：
(1) it is filtered after impregnating inorganic pigment 1-2 days with 2-3 times of deionized water, obtained filter residue 3-5 wash with distilled water
Secondary removal water-solubility impurity, in the case where power is 400-500W, microwave drying 2-3 minutes, obtains pigment and aluminate coupling agent, three
Ethylene diamine, polybutadiene epoxy resin are 20-25 in mass ratio:4:1:2 ratio is sent into micronizer, batch mixing 1-
1.5 hours, obtain the modified pigment that grain size is 0.5-10 μm；
(2) polystyrene is mixed by weight proportion with composite dispersing agent, fiber, flame retardant of magnesium hydroxide, filler material,
It is stirred 30-50 minutes under the mixing speed of 1000-1200r/min, is sent into pulverizer and crushes after cooling, it is big to obtain grain size
Small is 100-300 μm of mixture；
(3) above-mentioned modified pigment is sent into autoclave, carbon dioxide is added, adjust the pressure in autoclave
For 60-90MPa, temperature is 100-150 DEG C, and carbon dioxide is made to become supercritical fluid；
(4) it being stirred using magnetic stirring apparatus, post-modification pigment is completely dissolved in supercritical fluid within 3-5 hours, then
The mixture in step (2) is added, continues stirring 20-30 hours, maintains temperature-resistant reduction pressure to 1-5MPa, continues to stir
It 10-15 hours, is deflated by gas bleeder valve, thick color masterbatch is taken out after cooling；
(5) by above-mentioned thick color masterbatch by melting, extrusion, granulation, the ABS color master batch that particle size is 1-10mm is obtained.
Compared with prior art, it is an advantage of the invention that：
The present invention effectively enhances the compatibility with carrier, pigment is made to be uniformly dispersed, more preferably by the way that inorganic pigment to be modified
Coloring, and modified pigment does not allow fugitive color, it is more aesthetically pleasing, substantially prolong its service life.
The bamboo charcoal fiber of honeycomb microporous structure is mixed with carrier, auxiliary agent, elliptical shaped apertures have been covered in mixture.It will
Inorganic pigment is dissolved in supercritical carbon dioxide fluid, is penetrated into mixture after numerous hole after it, by decompression expansion,
Micron-sized inorganic pigment can be gradually deposited in mixture, carbon dioxide recoverable.
Supercritical carbon dioxide fluid viscosity is low, diffusion property coefficient is big, diffusion boundary layer is small, the inorganic face of unimolecule of dissolving
Material can be rapidly soaked into gap in mixture, and coloration efficiency is far above traditional handicraft, substantially reduce the production cycle, and
Color is uniform, aberration is smaller, colour stability greatly improves.
It, can using dispersant YY -5023, the dispersant of maleic anhydride grafted polyethylene wax, titanate coupling agent composition
The melt flow rate (MFR) of Masterbatch is improved, increases counter balance torque, the time reached needed for peak torque is shortened, in the shortest time
It is interior to obtain ideal dispersion effect, and dispersant dosage is reduced, reduce cost.
Flame retardant of magnesium hydroxide is cheap, and capacity of decomposition is high, and flame retarding efficiency is high, and suppression cigarette ability is strong, and hardness is small, to equipment
It rubs small, helps to extend equipment life.The magnesia that generates is a kind of high intensity, high heat-resisting material after magnesium hydroxide burning dehydration
Material can be used as protection wall isolation burning things which may cause a fire disaster and toxic and harmful gas, and the neutralising capacity of magnesium hydroxide and acid is strong, can neutralize plastics rapidly
Sour gas SO2, NOx, CO2 for being generated in combustion process etc..
ABS color master batch provided by the invention has good dispersibility and flame retardant property, low processing cost, preparation process
Simply.Bamboo charcoal fiber is added, antibiotic rate is up to 90% or more, and ultraviolet ray transmissivity is low, and anti-aging property is strong；When applied to ABS
When the coloring of product, have that uniform coloring, good flame resistance, antibiotic property is good, colour stability is high, aberration is small and to plasthetics machine
The advantages that tool performance is without influencing.
