Description

Polyolefin Resin Composition
Technical Field
The present invention relates to a polyolefin resin composition. More particularly, the invention relates to a polyolefin resin composition which is a composite resin composition with excellent scratch resistance and moldability for use in materials of electronic appliance housing and automobile parts.
Background Art General polypropylene resins have low specific gravity and good moldability and can easily be recycled. The polypropylene resins also exhibit excellent resistance to heat, solvent and chemicals. Polypropylene resins, however, are defective in scratch resistance and surface hardness. Especially, the polypropylene resins added with inorganic fillers in order to improve flexural rigidity and heat resistance are widely used in housing of home electronic products and in interior parts of automobiles. But, as content of talc is increased in the resin, flexural rigidity and heat resistance are improved while scratch resistance is lowered and, in case of complicated article, the molded article is not properly formed in injection molding. So far, much study has been made to solve these problems. As a typical example, Korean Patent No. 117,571 discloses a polypropylene resin having improved binding force between polypropylene matrix, rubber component and inorganic filler, by using inorganic filler treated with amino silane coupling agent and ethylene-alpha-olefin copolymerized rubber modified by ester of alpha,beta-unsarurated acid having epoxide functional group, and Korean Patent No. 52,816 discloses a polypropylene resin having improved binding force between polypropylene matrix and rubber component, thus improving scratch resistance and impact strength, by using ethylene-alpha-olefin copolymerized rubber modified by ester of alpha,beta-unsaturated acid having epoxide functional group and polyolefin modified by unsaturated carbon acid or its derivative. Also, Japanese laid open publication Sho-53-118,055 discloses a polypropylene resin having improved scratch resistance by using glass fiber or mica of flake type and Japanese laid open publication Sho-56-88,447 discloses a polypropylene resin having improved scratch resistance by confining ethylene content of polypropylene resin used as a matrix to some range.
But even with the above-mentioned methods, the improvement of scratch resistance is insufficient. Moreover, in the case of Korean Patent No. 117,571 and 52,816, which uses ethylene-alpha-olefin copolymerized rubber modified by ester of alpha,beta- unsaturated acid having epoxide functional group, flexural rigidity and fluidity of resin decreas as rubber components are added. Also, in the case of Japanese laid open publication Sho-53-118,055, which uses glass fiber or mica of flake type, fluidity of resin decreases and appearance becomes bad, and in the case of Sho-56-88,447, which confines ethylene content of polypropylene resin, impact strength is lowered as the content of ethylene which absorbs impact decreases, and moldability also decreases. Disclosure of the Invention
The object of the present invention is to overcome defects of prior art and provide a polyolefin resin composition with improved impact strength, moldability, fluidity, appearance and scratch resistance.
The polyolefin resin composition of the present invention comprises 100 parts by weight of polypropylene, 5 to 45 parts by weight of inorganic filler, and 2 to 20 parts by weight of silicon-grafted metamotphic polyethylene. The polyolefin resin composition of the present invention is novel resin composition which exhibits better scratch resistance, resin fluidity and moldability than prior art polyolefin resin composition while not deteriorating mechanical characteristics.
The present invention will now be described in detail. The example of polypropylene that can be used in the resin composition of the present invention is homopolymer, block copolymer, random copolymer or terpolymer, or mixture of these. The type of polypropylene may be changed according to the required characteristics of the product. In products requiring impact resistance, for example, block copolymer is used and when flexural modulus is more important than impact resistance, homopolymer is used.
The example of inorganic filler that is used in the resin composition of the present invention in order to reinforce physical properties of polypropylene resin is one or more of materials selected from the group consisting of talc, calcium carbonate, glass fiber, mica and silica. In particular, talc and calcium carbonate are preferable since they are effective in improving heat resistance, flexural modulus of elasticity and scale stability as well as cost effective considering efficacy. In the present invention, talc of average size of 5 ~ 10 micro meters and preferable content is 5 ~ 45 parts by weight. When talc content is below 5 parts by weight, scratch resistance is not substantially improved, and when talc content is over 45 parts by weight, the problem of bad appearance occurs. The silicon-grafted metamorphic polyethylene is prepared by mixing polyethylene resin, silicon oil, crosslinking agent and croslinking coagent, and by crosslinking the polyethylene and silicon by means of reaction extrusion method. The silicon-grafted polyethylene, other than the silicon oil, does not cause blooming phenomenon, is not sticky and has the advantage of reducing surface friction coefficient. Preferable content of the silicon-grafted polyethylene is 2 ~ 20 parts by weight, or more preferably, 5 ~ 10 parts by weight. When the content is below 2 parts by weight, it is difficult to improve scratch resistance, and when the content is over 20 parts by weight, there is a decrease in the flexural modulus of elasticity as well as the rise in the cost of production. Below, the present invention will be described in more detail with reference to examples.
