Abstract
The invention discloses low-gloss HIPS (high impact polystyrene) modified resin which consists of the following components in parts by weight: 66-86 parts of HIPS, 5-15 parts of polyethylene, 5-15 parts of minerals, 1-4 parts of compatilizer and 0.2-1 part of antioxidant. The low-gloss HIPS modified resin disclosed by the invention has the advantages of gloss controllability and good tensile property, bending property and impact strength; and since the polyethylene and minerals in the raw materials are very cheap, the production cost of the low-gloss HIPS modified resin disclosed by the invention is relatively low.
Description
Technical field
The present invention relates to resin art, be specifically related to a kind of low gloss HIPS modified resin.
Background technology
HIPS (polystyrene) resin is a kind of organic polymer material be prepared from for raw material with vinylbenzene and cis-1,4-polybutadiene rubber, its purposes is wide, consumption is large, usually for the manufacture of white domestic appliances product, as for the production of the shell of the products such as conditioner, televisor, computer, washing machine, refrigerator, suction cleaner and component, for the manufacture of the sheet material of the light current device of electrician, telecommunication, instrument, housing and component, and various daily life injection moulding articles for use and plastic toy goods.Because portioned product outward appearance is for the requirement of glossiness, and for the control of production cost, therefore market is badly in need of the HIPS modified resin wanting a kind of low-luster.
Summary of the invention
HIPS modified resin that the object of this invention is to provide a kind of low gloss and preparation method thereof.
In order to achieve the above object, technical scheme of the present invention is, a kind of low gloss HIPS modified resin, by weight, described low gloss HIPS modified resin consists of the following composition: HIPS66 ~ 86 part, polyethylene 5 ~ 15 parts, mineral 5 ~ 15 parts, compatilizer 1 ~ 4 part, 0.2 ~ 1 part, oxidation inhibitor.
Described low gloss HIPS modified resin consists of the following composition: HIPS786 part, polyethylene 10 parts, mineral 10 parts, compatilizer 3 parts, 1 part, oxidation inhibitor.
Described HIPS resin be PH-88FS, 532, PH-88E, GH-660 or 825G.
Described LDPE resin is LD400,1C7A, M200056, LD608 or 5000S.
Described mineral are calcium carbonate, talcum powder, wollastonite, kaolin or silica powder.Order number is between 1000 ~ 10000 orders.
Described compatilizer is maleic anhydride grafted polyethylene.Preferred compatilizer 5904.
Described oxidation inhibitor is β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid) pentaerythritol ester.
HIPS, as the body material of system, makes product material have stronger impact resistance, and lower water-absorbent; Mineral as the matting agent of whole system, add-on number affect the height of gloss, and the cost of mineral is lower, and mineral can increase the intensity of material in addition, reduce shrinking percentage; Polythene PE is the compatilizer of system, increase the com-patibilising effect of mineral and HIPS, and cost is lower; Compatilizer maleic anhydride grafted polyethylene is then the compatilizer of PE and mineral.
The present invention also provides a kind of preparation method of low gloss HIPS modified resin, and described preparation method has following steps:
Step 1, by HIPS66 ~ 86 part, polyethylene 5 ~ 15 parts, mineral 5 ~ 15 parts, compatilizer 1 ~ 4 part, 0.2 ~ 1 part, oxidation inhibitor adds in forcing machine, forms uniform mixture;
Step 2, regulates extruder temperature to be 160 ~ 220 DEG C, makes mixture be converted into molten state, by mixture mixing extrusion, and carry out granulation, obtain low gloss HIPS modified particles.
Described forcing machine is twin screw extruder.
Can select the starting material of different melting index according to the downstream processing methods of material, can be injection moulding, extrusion grade, plastic uptake, blown type.
The filling mineral of different meshes and whiteness can be selected according to the requirement of product and cost.
According to product to the requirement of glossiness Selective filling mineral in scope, filling proportion can be regulated.
Low gloss HIPS modified resin provided by the present invention can require carry out injection moulding according to mobility, and sample is prepared in extrusion sheet or blowing, plastic uptake, reduces material cost when ensureing properties.
The present invention utilizes mineral to increase the concavity and convexity of resin surface, makes light generation diffuse-reflectance, reaches the effect of delustring, and use PE as the interfacial compatibilizer of system, reduce the interfacial tension of mineral and HIPS, avoid system because the yellow dull colour of incompatible generation, may be used for white article.And by the ratio regulating mineral shared in system, change the concavo-convex degree of material surface, thus regulate the glossiness of material.
Low gloss HIPS modified resin of the present invention has the controllability of glossiness, good tensile property, bending property and shock strength; And because the price of polyethylene in raw material and mineral is all very cheap, so the present invention also has lower production cost, be suitable for very much manufacturing white domestic appliances.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read content of the present invention, these equivalent form of values fall within the application's limited range equally.
Embodiment
By HIPS, polyethylene, mineral, compatilizer, oxidation inhibitor, join in stirrer and be uniformly dispersed, again mixture is joined in forcing machine, extruder temperature is regulated to be 160 ~ 220 DEG C, mixture is made to be converted into molten state, by mixture mixing extrusion, and carry out granulation, obtain low gloss HIPS modified particles.
The proportioning of embodiment 1 ~ 3 is in table 1.
Table 1
Tested by low gloss HIPS modified resin prepared by embodiment 1 ~ 3, test result is in table 2.
