Description
Technical field
The present invention relates to field of material technology, and in particular to a kind of high glaze scratch resistance polycarbonate and preparation method thereof and
Using.
Background technique
Polycarbonate (PC) has because of its excellent mechanical property, thermal stability, dimensional stability and surface gloss
Extensive purposes, already development is one of most important engineering plastics.Plastics exempt from spraying due to its environmental protection, the advantages such as drop this at present
One of the development trend for already becoming plastic industry exempts from spraying PC and is also applied wherein, however due to surface scratch resistance energy
Power is poor to limit it in the application in the field.The general method for increasing surface hardness has the side such as modification, blending, plated film
Method, wherein filling-modified compared with simple economy.But relatively fewer on the research of the direction at present and easy influence glossiness, impact are strong
The important performances such as degree, so that the requirement for exempting from painted plastic be not achieved.
Summary of the invention
To solve the problems, such as that background technique is mentioned, the present invention provides a kind of high glaze scratch resistance polycarbonate, according to weight
The ingredient of proportion includes:
Further, ingredient according to the weight ratio includes:
Further, the PC resin melt index is 3-15g/min.
Further, the MBS resin is insensitive to shearing, and is suitable for PC toughening and influences on other performances small.
Further, the scratching resistant is low molecular weight propylene acids particular polymer, can be hard on the raising surface PC
Its glossiness and transparency are not influenced while spending.
Further, the silicone powder white in appearance is powdered, and average grain diameter is less than 5 μm.
Further, the antioxidant selects the (β-[3,5- di-tert-butyl-hydroxy phenyl] of Hinered phenols antioxidant 1076
Propionic acid n-octadecyl alcohol ester) it is compounded with phosphite ester antioxidant 168 (three [2,4- di-tert-butyl-phenyl] phosphite esters), compounding
Ratio is 1:1.
Further, the lubricant is pentaerythritol tetrastearate (PETS).
The present invention also provides a kind of preparation methods of above-mentioned high glaze scratch resistance polycarbonate, comprising the following steps:
Step 1: by the PC resin matched according to constant weight, MBS resin, scratching resistant, silicone powder, antioxidant, lubrication
Agent is added in batch mixer and mixes 5-10min, obtains pre-mixed material；
Step 2: pre-mixed material is added twin-screw extrude by main spout, melted through double screw extruder
It squeezes out, using water cooling bracing pelletizing mode, high glaze scratch resistance polycarbonate (PC) is made using screening and dewatering.
The invention also includes application of the above-mentioned high glaze scratch resistance polycarbonate in terms of exempting from sprayed product.
Compared with prior art, the present invention has a characteristic that
(1) scratching resistant that adds of the present invention is low molecule acrylic acid particular polymer, by addition molecular weight it is low third
Olefin(e) acid class particular polymer improves the surface hardness of polycarbonate (PC), this is because the low molecular weight propylene acids of hard is special
Different polymer work in-process is easy to be covered on frosting formation anti-scratch layer, to reach scratch resistant purpose.Simultaneously because
The presence of low molecular weight propylene acids polymers is processed more simple so that melt viscosity reduces.
(2) although it has also been found that addition scratching resistant enables to the scratch resistance effect promoting of substrate, with anti-
Scratching increasing for agent additive amount instead weakens the impact strength of substrate, if by addition MBS resin come toughening, on the one hand, need
Largely to add MBS resin just can make impact strength considerable, and on the other hand, the bloom that can but make material is added in a large amount of MBS resins
Property it is impaired, the effect for exempting from spraying is not achieved.For this purpose, not only there is help present invention discover that passing through the silicone powder of addition specific quantity
Modified material crystallization, improves impact strength, improves plastic processing mobility and release property, additionally it is possible to improve material surface gloss,
And the addition of silicone powder can reduce the usage amount of scratching resistant and guarantee that material surface has good adhesion strength.But
It adds excessive silicone powder and is not further added by surface scratch resistance, while also will affect mechanical property and glossiness.
In conclusion the present invention exactly makees in the scratching resistant of specific additive amount, MBS resin and the collaboration of silicone powder three
A kind of modification material of polycarbonate that high glaze scratch resistance effect is good could be obtained with lower, which is improving adhesion strength
The important performances such as glossiness, impact strength have been combined, have there is good and balanced mechanics, heat and electrical property as substrate PC
Can, and melt viscosity is lower, it is more easy to process.And the preparation method of bloom scratch resistance PC of the present invention, preparation is simple, can grasp
The property made is strong, easy to implement, large-scale industrial production can be realized by means of existing mature technology double screw extruder,
Exempt from spraying field with boundless application prospect.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention,
Technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is the present invention one
Divide embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making
Every other embodiment obtained, shall fall within the protection scope of the present invention under the premise of creative work.
It should be noted that in the examples where no specific technique or condition is specified, it is described according to the literature in the art

Table 1
For the ease of comparing the coordinative role proved between component provided by the invention, the present invention also provides pairs of such as table 2
Ratio 1-5 (each component matches according to parts by weight):
Table 2
The following are the preparation methods of above-described embodiment and comparative example (to weigh each implementation by the parts by weight proportion of Tables 1 and 2
The component of example):
PC resin is placed in drying box by the first step, under the conditions of 120 DEG C, 3h is dried, then by the PC resin after drying
It is added in high-speed mixer with MBS resin, scratching resistant, silicone powder, antioxidant, lubricant and mixes 5min, mixing machine turns
Speed is 300r/min, is uniformly mixed in batch mixer and obtains pre-mixed material；
Above-mentioned pre-mixed material is added in double screw extruder by second step from main spout, through double screw extruder
Melting extrusion, extruded stock use water cooling bracing pelletizing, modification material of polycarbonate are made using screening and dewatering.Specifically, double
The screw slenderness ratio of screw extruder is 40:1, engine speed 300r/min, in double screw extruder from feed zone to head
Each conversion zone temperature be respectively 230 DEG C, 240 DEG C, 250 DEG C, 250 DEG C, 250 DEG C, 250 DEG C, 250 DEG C, 250 DEG C, 260 DEG C, 260
