The resin composition of the present invention is a resin composition comprising a) 150 to 350 parts by weight of a heat-resistant resin, and c) an unsaturated hydrocarbon having 2 to 6 carbon atoms, an acrylate-based compound And 0.2 to 20 parts by weight of a terpolymer copolymerized with carbon monoxide as a monomer. According to the resin composition of the present invention, paintability, fluidity, chemical resistance and impact strength are all improved, so that the defect rate can be minimized and the product can be used in products exposed to harsh environments.
Description
The present invention relates to a resin composition, and more particularly, to a resin composition which is formed into a product such as an automobile, a TV, and a monitor and has improved paintability upon application.
BACKGROUND ART Acrylonitrile-butadiene-styrene (ABS) resin is a copolymer derived from acrylonitrile, butadiene, and styrene, and is excellent in impact resistance, chemical resistance, Weather resistance and the like, and is excellent in molding properties such as injection molding and extrusion molding, and is excellent in secondary workability and is used in various industries.
However, even in such excellent properties, when the ABS resin is treated with a solvent (thinner or the like) for the purpose of coating or the like, the surface component of the rubber component becomes severe due to the component of the strong solvent and the adhesion surface between the paint and the molded resin becomes uneven Large and small cracks are generated, which leads to pin holes which are defective in coating.
In order to solve such a problem, Japanese Patent Publication No. 7-47679 discloses a method of diluting a component of a solvent and a styrene-acrylonitrile (SAN) having a high content of acrylonitrile (AN) ) Is proposed to prevent damage to rubber components. However, there is an inconvenience that the diluted solvent should be exposed to the molded resin for a long time, and when styrene-acrylonitrile (SAN) having a high content of acrylonitrile (AN) is used, there is a problem that the chemical resistance and gloss characteristics are lowered .
In addition to this, various studies have been made, such as increasing the butadiene rubber content of the ABS resin, increasing the rubber size, increasing the molecular weight, etc. However, in this case, the residual stress of the molded product increases due to the decrease in fluidity, There is a limit to improvement.
It is an object of the present invention to provide a resin composition having chemical resistance and excellent impact strength which are resistance to a solvent used in coating in a state in which fluidity is secured in order to improve paintability.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a resin composition,
a) 100 parts by weight of an acrylonitrile-butadiene-styrene (ABS) resin,
b) 150 to 350 parts by weight of a heat resistant resin, and
c) from 0.2 to 20 parts by weight of a terpolymer having an unsaturated hydrocarbon having a carbon number of C2 to C6, an acrylate-based compound, and a terpolymer copolymerized with carbon monoxide as a monomer. It is possible to improve the paint pinhole defect at the time of coating due to the improved chemical resistance, fluidity and other physical properties of the resin composition of the present invention and improved paint performance.
The b) heat-resistant resin includes styrene,? -Methylstyrene,? -Ethylstyrene, p-ethylstyrene, and vinyl toluene. (AMS) may be preferably used. The aromatic vinyl compound may be used alone or in combination of two or more.
The unsaturated hydrocarbon (c) includes an alkenyl group substituted with a fatty acid or an unsubstituted alkenyl group. Preferably, an unsubstituted alkene group can be used, and more preferably unsubstituted ethylene can be used.
The acrylate compound of c) includes n-butyl acrylate, ethyl acrylate, methyl acrylate, and isobutyl acrylate. Preferably, n-butyl acrylate can be used.
The resin composition of the present invention improves the paintability, chemical resistance, flowability and impact strength by containing a small amount of the terpolymer in the ABS resin.
In the case of using a ternary copolymer in which ethylene, n-butyl acrylate and carbon monoxide monomer are copolymerized, pinhole defect does not occur and impact strength is improved. If the amount of the ternary copolymer contained in the ABS resin is small and is included in the amount of 1.6 to 7.0 parts by weight based on 100 parts by weight of the ABS resin, the paintability, chemical resistance, fluidity and impact strength are improved .
The following detailed description of the invention is set forth to be in a specific embodiment, in which the invention may be practiced, and will be described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. Accordingly, the following detailed description is not to be taken in a limiting sense, and the scope of the present invention should be construed as encompassing the contents of the claims and all the equivalents thereof.
Hereinafter, the present invention will be described in detail.
<ABS resin>
The ABS resin can be produced by graft-polymerizing an aromatic vinyl compound (styrene) and a vinyl cyanide compound (acrylonitrile) on a conjugated diene rubber (butadiene rubber). The conjugated diene rubber typically uses butadiene rubber.
The particle size and gel content of the butadiene rubber affect the impact strength and workability of the resin. In general, the smaller the particle size of the butadiene rubber, the lower the impact resistance and processability. The larger the particle size, the better the impact resistance. The lower the gel content, the more swollen the monomer is contained in the butadiene rubber and the polymerization takes place, so that the apparent particle diameter is increased, so that the impact strength is improved.
However, when the content of butadiene rubber is large and the particle size is large, the graft rate is decreased. If the graft ratio is lowered, the amount of ungrafted ABS resin increases, which causes a change in inherent properties (thermal stability deterioration). Also, when the particle size of the butadiene rubber is increased, the size of the anchor hole during the etching process becomes excessively large, and the adhesion may be deteriorated, resulting in deterioration of paintability.
Therefore, the ABS resin of the present invention can adopt various particle diameters of the butadiene rubber while maintaining the inherent physical properties. For example, it is preferable to use a rubber having a butadiene rubber particle diameter in the range of 600 Å to 5000 Å.
Butadiene rubbers include diene rubbers such as polybutadiene, polystyrene-butadiene and polyacrylonitrile-butadiene, saturated rubbers obtained by adding hydrogen to the diene rubbers, C1-C8 Isoprene rubber, chloroprene rubber, and ethylene-propylene (EPM) rubber such as alkyl acrylate (Alkylacrylate), polyacrylate, ethylhexylacrylate and the like, isoprene rubber, And ethylene-propylene-diene (EPDM) rubber, which can be an ABS resin.
The graft polymerization process can be produced by graft-copolymerizing an aromatic vinyl compound and a vinyl cyanide compound on a butadiene rubber. As a specific example, a composition comprising 15 to 40 parts by weight of an aromatic vinyl compound, 5 to 20 parts by weight of a vinyl cyanide compound, 0.2 to 0.6 parts by weight of an emulsifier, 0.2 to 0.6 parts by weight of a molecular weight adjuster, 0.1 to 0.5 parts by weight of the grafted ABS resin can be prepared.
The aromatic vinyl compound may be at least one selected from the group consisting of styrene,? -Methylstyrene,? -Ethylstylnene, o-bromostryene, p-ethylstyrene p-bromostryene, p-chlorostryene, p-methylstyrene, vinyl toluene, and derivatives thereof.
The vinyl cyanide compound may be selected from the group consisting of acrylonitrile, methacrylonitrile, ethacrylonitrile, and derivatives thereof.
The polymerization reaction temperature is suitably from 45 캜 to 80 캜, and the polymerization time is preferably from 3 to 5 hours. In the graft polymerization, each raw material monomer may be added in a batch, multistage, or continuous manner. In order to improve the grafting rate and minimize the formation of coagulation product, a multi-stage divided administration method or a continuous administration method Is preferably used.
The emulsifying agent may be used as a mixture of at least one selected from the group consisting of alkyl aryl sulfonates, alkali metal alkyl sulfates, sulfonated alkyl esters, fatty acid soaps and rosin acid alkali salts.
As the molecular weight regulator, tertiary dodecylmercaptan may be used. Examples of the polymerization initiator include peroxides such as curing hydroperoxide, diisopropylbenzene hydroperoxide, persulfate and the like, sodium formaldehyde sulfoxylate, sodium ethylenediamine tetraacetate , An oxidation-reduction catalyst system comprising a mixture with a reducing agent such as ferrous sulfate, dextrose, sodium pyrophosphate, sodium sulfite and the like can be used.
After completion of the polymerization, an antioxidant and a stabilizer are added, and the resulting mixture is agglomerated with an aqueous solution of sulfuric acid at a temperature of 80 ° C or higher, followed by dehydration and drying to prepare a grafted ABS resin.
Such a polymerization method includes an ordinary polymerization method such as an emulsion polymerization method, a suspension polymerization method, a solution polymerization method, a bulk polymerization method, a method using a suspension polymerization and a bulk polymerization together, and a system using both emulsion polymerization and bulk polymerization .
As a specific example of the bulk polymerization method, butadiene rubber or styrene-butadiene rubber is dissolved in a solution prepared by dissolving a styrene-based monomer and an acrylonitrile-based monomer in a reaction medium such as ethylbenzene or toluene. Subsequently, an appropriate amount of a reaction initiator, a molecular weight modifier and other additives are mixed and then heated, thereby obtaining an ABS resin produced by a bulk polymerization method.
As a specific example of the production method by the emulsion polymerization method, the butadiene rubber is transferred to the reactor, and styrene, acrylonitrile, emulsifier and initiator are injected into the reactor. When the reaction is complete, add the antioxidant, coagulant and steam in the meat. Thereafter, the precipitated slurry is filtered and centrifuged, washed and dehydrated, and then dried to obtain an ABS resin.
≪ Heat resistant resin &
The heat-resistant resin (b) of the present invention includes those prepared by copolymerizing a polymer having heat-resistant characteristics within a certain temperature range, an aromatic vinyl compound, and a vinyl cyanide compound.
For example, the polymer may be selected from the group consisting of N-phenylmaleimide, N-phenylmalieciacid, styrene maleic anhydride and alpha-methylstyrene Lt; / RTI > The aromatic vinyl compound may be at least one selected from the group consisting of styrene, alpha-methylstyrene, alpha-ethylstyrene, and para-methylstyrene. It is preferable to use alpha methyl styrene. The vinyl cyanide compound includes acrylonitrile, methacrylonitrile, and ethacrylonitrile.
The heat-resistant resin is preferably contained in an amount of 150 to 350 parts by weight based on 100 parts by weight of the ABS resin. If the content of the heat-resistant resin is less than 150 parts by weight, the heat resistance may be poor. If the content of the heat-resistant resin exceeds 350 parts by weight, impact strength may be significantly decreased.
≪ Ternary copolymer &
The terpolymer refers to an unsaturated hydrocarbon having 2 to 6 carbon atoms, an acrylate compound and a carbon monoxide monomer copolymerized. The ternary copolymer exemplified below improves the chemical resistance, which is resistance to a solvent used in coating the resin composition of the present invention, and increases fluidity.
The unsaturated hydrocarbons include substituted or unsubstituted alkene groups. Ethylene can be preferably used. The acrylate compound includes n-butyl acrylate, ethyl acrylate, methyl acrylate, and isobutyl acrylate. Preferably, n-butyl acrylate can be used.
As a specific example, the terpolymer may be represented by the following general formula (1).
As shown in Formula 1, the terpolymer is preferably a copolymer comprising ethylene, carbon monoxide, and n-butyl acrylate as monomers. The terpolymer may be contained in an amount of 0.2 to 20 parts by weight based on 100 parts by weight of the ABS resin. When the content of the terpolymer is less than 0.2 parts by weight, the fluidity and chemical resistance are poor. When the content is more than 20 parts by weight, fluidity and chemical resistance can be secured, but the heat resistance is poor. Preferably, the terpolymer may be contained in 1.6 to 7 parts by weight. The content of the monomers of the terpolymer may vary, but preferably the content ratio of ethylene, carbon monoxide, and n-butyl acrylate is preferably 57:13:30.

- Preparation of Examples 1 to 3 and Comparative Examples 1 and 2
Examples 1 to 3 and Comparative Examples 1 and 2 were prepared using the raw materials having the above-described specifications in the amounts shown in Table 1 below.
<Table 1> Preparation of Examples and Comparative Examples
Examples 1 to 3 and Comparative Examples 1 and 2 were kneaded at 250 ° C in a twin-screw extruder, and then subjected to injection to prepare specimens. The flowability, paintability, chemical resistance, Izod impact strength and heat distortion temperature were measured by the following method Respectively.
≪ Test Example 1 >

≪ Test Example 2 >
Take 10 cm X 10 cm of specimen, degrease with isopropyl alcohol, and spray black paint. Five minutes after the spraying, a clear paint was sprayed and dried in an oven at 85 캜 to observe whether pin-holes were generated. The results of the paintability measurement are shown in Table 1.
A, B and C classification levels shown in Table 1 were judged based on the following criteria.
A: No pinhole occurred
B: 1 ~ 5 corner holes
C: More than 6 corner holes
≪ Test Example 3 >
A 200 mm X 12.7 mm X 3.2 mm specimen was fixed to a curvature jig having a strain of 1.7% and a time for generating a crack in the specimen after coating 1 cc of a thinner was measured. The results of the chemical resistance test are shown in Table 1.
≪ Test Example 4 > Izod impact strength
A 3.2 mm thick specimen was taken according to the ASTM D 256 method and the Izod Impact Strength was measured to measure the resistance (absorbed energy) against impact while notching. The impact strength was confirmed as shown in Table 1.
≪ Test Example 5 >
A 6.35 mm thick specimen was taken according to the ASTM D 648 method and the heat distortion temperature was measured under a load of 18.6 kg. Table 1 shows the results of measurement of heat distortion temperature.
Comparing the examples 1 to 3 and the comparative example, all of the comparative examples, which are ABS resins not containing the terpolymer, produced pinholes as grade C in all of the paintability tests. On the other hand, in Examples 1 to 3, pinholes were not generated as Class A due to the inclusion of the terpolymer. It was confirmed that the appearance problem, that is, pinhole generation problem, could be solved by the inclusion of the terpolymer.
With respect to improvement in paintability, it was confirmed that the ternary copolymer affects the chemical resistance and fluidity improvement of durability against solvents such as thinner. From the viewpoint of chemical resistance, Examples 1 to 3 were found to be 25 to 50 times higher than those of Comparative Examples, and in terms of fluidity, Examples 1 to 3 were higher than Comparative Examples.
With respect to impact strength, Examples 1 to 3 were higher than Comparative Example 1. It can be seen that the ABS resin containing the terpolymer according to the present invention has improved paintability, fluidity, chemical resistance and impact strength. From the viewpoint of thermal deformation temperature, Examples 1 to 3 were somewhat lower than Comparative Example 1, but it was found that the difference was small.
Comparing the physical properties of Examples 1 to 3 in order to confirm the change in physical properties according to the content of the terpolymer, the coating properties, fluidity and chemical resistance were improved as the content of the terpolymer increased. In particular, it was found that the chemical resistance, which is a durability against a strong solvent, is greatly improved during coating.
As described above, the resin composition of the present invention improves the paintability, chemical resistance, flowability and impact strength by containing a small amount of the ternary copolymer in the ABS resin.
When a terpolymer copolymerized with ethylene, carbon monoxide or n-butyl acrylate monomer is added, not only the pinhole defect but also the impact strength is improved. If the amount of the ternary copolymer contained in the ABS resin is small and is included in the amount of 1.6 to 7.0 parts by weight based on 100 parts by weight of the ABS resin, the paintability, chemical resistance, fluidity and impact strength are improved .
