Description
Technical field
The present invention relates to a kind of macromolecular material, refer in particular to a kind of delustring PC/ABS automobile instrument panels material and its
Preparation method.
Background technology
Acrylonitrile-butadiene-phenylethylene（ABS）With impact, thermostability, lower temperature resistance, chemical proofing and electricity
Gas function admirable, also with easy processing, product size is stable, lustrous surface property is good the features such as, so extensively application machinery, vapour
The industrial circles such as car, electronic apparatus, instrument and meter, weaving and building, are one of five big general-purpose plastics, but it also has some to lack
Point limits polystyrene and uses in wider field, because its hardness is more crisp than larger and performance, at some
Material based on acrylonitrile-butadiene-phenylethylene cannot be used in the environment of needing excellent toughness, needed for this for third
Alkene is fine-and the existing shortcoming of butadiene-styrene is modified and uses field to increase which.
Merlon（PC）Its good toughness, dimensionally stable, so can by add PC improve ABS toughness.But due to
The glossiness of ABS and PC is all higher, and meter for car disk needs surface matt effect, so needing to carry out at delustring material
Reason.
Cause the compatibility of material poor as delustering agent is added, it is necessary to add compatilizer in the PC/ABS systems,
Improve acrylonitrile-butadiene-phenylethylene by compatilizer to have concurrently come two kinds of matrix trees so as to obtain with the compatibility of Merlon
The high performance alloys of lipid energy
The content of the invention
The technical problem to be solved is to provide a kind of delustring PC/ABS automobile instruments disk material and its preparation side
Method, to the glossiness for reducing material while acrylonitrile-butadiene-phenylethylene toughening modifying, has preferably comprehensively so as to obtain
The modified propylene of mechanical property and appearance requirement is fine-butadiene-styrene material.
The technical scheme that adopted of technical problem for solving the present invention is：A kind of delustring PC/ABS automobile instrument panel materials are provided
Material, including the raw material of following parts by weight：
Another technical scheme that adopted of technical problem for solving the present invention is：One kind is provided and prepares delustring as above
The method of PC/ABS automobile instrument disk materials, comprises the following steps：
Step one, acrylonitrile-butadiene-phenylethylene are dried 4 hours in 80 DEG C of baking oven, and Merlon is at 120 DEG C
It is dried 4 hours in baking oven.
Step 2, composition of raw materials is weighed according to the ratio of parts by weight, mixing 6-10 minutes in high-speed mixer obtains
Mixture；
Step 3, the mixture mixed in step 2 is carried out in double screw extruder extruding pelletization, twin screw is squeezed
Go out machine feed end temperature is set as 150-170 DEG C, area's temperature 190-210 DEG C, two area's temperature 205-225 DEG C, three area's temperature
215-235 DEG C, four area's temperature 215-235 DEG C, 195-215 DEG C of head, 1～2min of the time of staying, pressure are 8-14MPa.
Compared with prior art, the present invention passes through acrylonitrile-butadiene-phenylethylene (ABS) and Merlon（PC）In phase
Hold agent and lower alloy material of the formation with high impact resistance of toughener effect, while by adding homemade delustering agent pairing
Just face glossiness carries out delustring process to golden material.As the good toughness of Merlon causes it and ABS-benzene second
The not enough shortcoming of acrylonitrile-butadiene-phenylethylene toughness can effectively be made up in alkene cohesive process, compatilizer styrene-
Propylene is fine-glycidyl methacrylate effect under, acrylonitrile-butadiene-phenylethylene and Merlon can be good at phase
Hold, consequently facilitating scale processing., due to being the Merlon containing silane component, element silicon is in material for self-control delustering agent
The middle effect that can play fire-retardant light source, while the ground calcium carbonate for adding can also play extinction effect, the two is acted in compatilizer
Good delustering agent can be formed after lower uniform mixing.Simultaneously because the proportion of ground calcium carbonate is higher, which adds and causes delustering agent
Material surface is easily distributed in, material matt effect can be improved.Material obtained by the present invention not only has good impact
Can, and cut down in the glossiness to material surface, application has obtained very big extension.Additionally, the present invention is carried
The composite material and preparation method thereof for going out, simple production process need not add complex device, and with low cost.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
The present invention by add Merlon come toughened acrylic it is fine-butadiene-styrene, while wherein add benzene second
Alkene-propylene is fine-glycidyl methacrylate improving both compatibilitys because acrylonitrile-butadiene-phenylethylene and poly-
The Miscibility of both carbonic esters is not so good, if being added without compatilizer, co-mixing system can be in two kinds of resin materials
Junction form a small amount of layering, so as to form fault structure, this will not only improve acrylonitrile-butadiene-phenylethylene
Toughness, can cause the performance of co-mixing system to reduce on the contrary, thus to add in system bulking agent styrene-propene it is fine-methyl
Glycidyl acrylate, after bulking agent is added in system, can improve surface both com-patibilising effect so that two kinds of matrix trees
Fat reach it is well co-melting, so as to whole system shows more excellent comprehensive mechanical property.Self-control delustering agent is added to conjunction
Jin Zhonghou intercepts the effect of light by which, enables to material and has matt surface.
