Description
Technical field
The present invention relates to a kind of thermoplastic resin composition.More specifically; the thermoplastic resin of grafted ABS polymkeric substance and heat-resistant copolymerized thing comprises acryl resin, superoxide based additive or crosslinking additives; thereby; the cold stress albefaction (cold stresswhitening) of this thermoplastic resin is lowered, important hot tool weldability (hot-tool weldability) and painted and coating extension characteristics are enhanced and keep splendid thermotolerance and mechanical characteristics in aftertreatment; as tensile strength, bending strength and other characteristic, and make thermoplastic resin itself have low gloss.
Background technology
Recently, with demand to the lightweight automobile, in order to develop the light-weight material inside, carry out many acrylonitrile-butadiene-styrene (ABS) (ABS) resins that efforts be made so that and had stable on heating research, wherein ABS resin has good shock resistance, chemoresistance and workability etc.
As making ABS (acrylonitrile-butadiene-styrene (ABS)) resin have stable on heating method, have the method that good stable on heating multipolymer and grafted ABS polymkeric substance prepare thermotolerance ABS by mixing and be proposed.United States Patent (USP) the 3rd, 010,936 and 4,659, No. 790 the method for preparing the thermotolerance ABS resin is disclosed, wherein, the alpha-methyl styrene that the vinylbenzene of used part or all of amount is had an excellent heat resistance in the preparation of heat-resistant copolymerized thing substitutes.Publication number is Japanese publication and the United States Patent (USP) the 4th of clear 58-206657, clear 63-162708, clear 63-235350, the method etc. that preparation comprises the method for the method of thermotolerance ABS resin of maleimide compound and mixed polycarbonate and ABS and add inorganic substance in ABS is disclosed for 757, No. 109.
These thermotolerance ABS resin are prepared as pellets usually, thereby the preparation of finished product needs the procedure of processing as jet molding or extrusion molding.
Under at low temperatures, especially being lower than 0 ℃ temperature, store or when transportation thermotolerance ABS resin or processing layered product tonal variation that may take place not expect and common albefaction.
If be known as the phenomenon of " cold stress albefaction ", then the priming color of layered product disappears, and this is especially deleterious to painted layered product.
In order to use in thermotolerance ABS resin or processing layered product, the reduction degree of cold stress albinism should be splendid.
Therefore, need increase thermotolerance ABS resin with extremely excellent cold stress albefaction reduction, and, as the method for this thermoplastic resin of preparation, various methods (publication number is Korea S's publication of 2002-0047285) of in thermoplastic polymer, adding the organopolysiloxane of 10~200ppm have been researched and developed.
And procedure of processing and back workability that the thermotolerance ABS resin has behind many jet moldings are important.Especially, the back lampshade of automobile is by injection plexiglass (PMMA), the PMMA sheet is interconnection to be produced for the surface of evenly injection and beautiful outward appearance make with thinner coating, deposition of aluminum and with constant temp and pressure, thereby, the coating stage in preparation process, if the ductility of coating is lowered, then must use thinner extraly, and that thinner can cause the destruction of coating procedure and the deposition appearance in waste and the al deposition process is destroyed.And, because the fusion zone in the generation hot tool welding process, so the reduction of hot tool weldability, and owing to the bonding unevenly evil matter that causes outward appearance.Therefore, the polymethylmethacrylate (PMMA) that uses as the back lampshade of automobile must be splendid aspect hot tool weldability, the painted and coating ductility.
And, along with recent user's organoleptic quality requires the raising of level, to the increase in demand of low gloss resins with more graceful atmosphere.In addition because environmental problem significantly changes, therefore, low gloss resins just towards direct use, avoid low gloss to apply or use the processing of liner to apply direction developing.
Prepare the used cardinal principle of this low gloss resins and be, the slipperiness of control resin surface is to the scope that surpasses visible light, thereby incident light is scattered, therefore, and the performance low gloss effect.Explain method more specifically by following three examples.
The first, as the method that is used to improve acrylonitrile-butadiene-styrene resin, use by what mass polymerization obtained to have a large diameter rubber grain greater than 2 μ m.But by the resin of this method preparation, its low gloss effect is not remarkable, and shock resistance and thermotolerance are relatively poor.
The second, in resin, introduce the method have greater than the low gloss filler of the granularity of 5 μ m.Resin by this method preparation shows splendid formability, still, low gloss characteristic aspect deficiency, and especially, the deterioration of resistance to impact shock is serious.
The 3rd, by using the method for preparing resin as the graft polymerization as the monomer of ethene-unsaturated carboxylic acid and the acrylonitrile-butadiene-styrene (ABS) polymkeric substance by emulsion polymerization prepared of properties-correcting agent.
Resin by the preparation of these methods shows splendid low gloss characteristic and all is being good aspect shock resistance and the various physical properties, therefore is widely used in making resin to have the low gloss effect.
But for use above-mentioned resin in splendid heat-resistant resin, its thermotolerance is relatively poor.And, when above-mentioned resin being applied to the weathering resistance resin that recent its consumption increases, as in the acrylonitrile-butadiene-styrene resin time, the weathering resistance variation.
