Description
Technical field
The invention belongs to technical field of material, and in particular, to a kind of high brilliant black makrolon material and its preparation
Method.
Background technique
Polycarbonate (PC) is had excellent performance, and has tough and rigid mechanical property, unnotched impact strength is in engineering plastics
In rank first, creep resistant is good, and glass transition temperature is high, can be used continuously in the range of 120 DEG C -130 DEG C, electrical insulating property
It is good with dimensional stability.With performance close to compared with polymethyl methacrylate, the impact resistance of polycarbonate is good, refractive index
Height, processing performance is good, and not needing additive just has UL94V-2 grades of flame retardant property.
Application of polycarbonate (PC) material on automotive upholstery, with irreplaceable excellent of following other class materials
Point:
1) superior impact resistance, cyclopentadienyl before impact strength ranks in thermoplastic；
2) good covering with paint property and the adhesion to cover film；
3) dimensional stability of height；
4) component installation is integrated into one；
5) design and process great flexibility application；
6) linear expansion coefficient is low, and thermal expansion coefficient is small.
However, the melt viscosity of PC is big, mobility, wears no resistance at solvent resistance, to notch sensitive.Polycarbonate it is resistance to
Mill property is poor.Some polycarbonate devices for purposes easy to wear need to carry out specially treated to surface.Polycarbonate is acidproof, resistance to
Oil.Polycarbonate not ultraviolet resistance, intolerant to highly basic.
For makrolon material, the Chinese patent of Publication No. CN108148372A discloses a kind of improvement polycarbonate
Weatherable polycarbonate dedicated parent material of dedicated parent material weatherability and preparation method thereof.Polycarbonate is a kind of tough thermoplasticity
Resin.Polycarbonate is colorless and transparent, heat-resisting, shock resistance, there is good mechanical performance in commonly used temperature.Polycarbonate
Weak acid resistant, resistance to weak base, resistance to neutral oil, not ultraviolet resistance, intolerant to highly basic.Main performance defect is that stability to hydrolysis resistance is not high enough,
To notch sensitive, resistance to organic chemistry moral character, resistance to scratch is poor, and being exposed in ultraviolet light for a long time can turn to be yellow.Therefore, by poly- carbonic acid
When ester prevents weather-proof product for manufacturing requirement, it is necessary to carry out anti-aging processing.Polycarbonate dedicated parent material can be significantly improved
Weather resistance, so that makrolon material is improved security performance when in use.However, polycarbonate provided by the patent is dedicated
Masterbatch, main purpose are promotion weatherability, and the resistance to highly basic and resistance to purple light performance boost for makrolon material are unobvious.
Summary of the invention
Above-mentioned to solve the problems, such as, the purpose of the present invention is to provide a kind of high brilliant black makrolon material and its systems
Preparation Method, the material possess excellent high glaze, high blackness, high tenacity, weatherability, dimensional stability, high intensity, have centainly
Wear resistance, addition carbon black etc. pigment have the characteristic of high blackness, while guaranteeing that the toughness of material does not reduce, as exterior trimming parts
Weatherability is excellent, there is certain wear resistance, substitutes imported material, reduces the cost of material.
In order to achieve the above objectives, the technical scheme is that
A kind of high brilliant black makrolon material, the material include the ingredient of following parts by weight: polycarbonate: 20~30

15 minutes, obtain mixed material；
4) double screw extruder is added in mixed material, the barrel temperature of the double screw extruder is controlled 210~270
DEG C, it squeezes out, pelletizing, obtains the high brilliant black makrolon material.
The beneficial effects of the present invention are:
The high brilliant black makrolon material of preparation is to carry out rationally effective screening from basic material and carbon black, adopt
With the PC of high molecular weight and the carbon black of different-grain diameter, the auxiliary agents such as toughener, UV absorbent, antioxidant, lubricant are added, together
Sheared in Shi Xuanyong arrangement screw-rod structure and reasonable extrusion process.
Polycarbonate (PC) is in the inorganic fillers process such as addition carbon black since Strong shear be easy to cause strand disconnected
It splits, the reduction of one's share of expenses for a joint undertaking amount is caused to cause toughness very poor.Addition antioxidant and lubricant can effectively reduce screw rod shearing and cause to drop
Solution.Ensure the mechanical property and hot property of material.Addition toughener can make rubber phase deformation absorb energy raising toughness of material.
Addition UV absorbent can effectively improve the weatherability of material.Polycarbonate (PC) material that the present invention develops is a kind of bloom
Damp, high blackness, high tenacity, weatherability be excellent, composite material with certain wear resistance.Possess lower cost and good
Performance, no matter market is all to have good prospect still in overseas market at home.
Moistened using PC and ultra-fine grain diameter carbon black the addition organosilicon toughener and heavy duty detergent polysiloxanes of high molecular weight
The compound double screw extruder with shearing screw thread arrangement in warp such as lubrication prescription is blended, and addition antioxidant, UV absorbent, coupling agent etc. help
Agent.Under reasonable process conditions, this high brilliant black PC material is produced.
The ultra-fine grain diameter carbon black that the present invention uses disperses by the double screw extruder of specific arrangement threaded block, and addition is efficient
Type polysiloxanes lubrication reinforces dispersion of the carbon black in polycarbonate (PC) material, keeps the blackness of material and glossiness high, reduces
Influence to the mechanical property of materials, comprehensive performance are substantially improved.
Polycarbonate (PC) commonly uses the toughener of butadiene rubber system, and toughening effect is good, but weatherability is poor.Acrylic acid
Rubber toughening agent, toughening effect is preferable, and weatherability is excellent, but coloring is poor.The present invention uses organosilicon toughener, toughening effect
Fruit is good, and weatherability is excellent, while can promote the wearability of material, has synergistic effect with heavy duty detergent polysiloxanes.Comprehensive performance
It is substantially improved.
The heavy duty detergent polysiloxane emollient that the present invention uses, this auxiliary agent can effectively reduce material and rub in extrusion process
It wipes, reduces the decline of the mechanical performance as caused by shearing.The hardness of raising material surface and smooth degree, make the wearability of material
Enhancing.The mechanical property and hot property that material after this auxiliary agent is added significantly improve.The abrasion of extruder is reduced simultaneously and reduces energy
Consumption.
