The present invention relates to a rubber-reinforced resin composition for coating, which has excellent impact resistance. It has been known to improve the impact strength of a resin composition by adding diorganopolysiloxane to a rubber-reinforced resin composition such as ABS resin (Japanese Unexamined Patent Application Publication No. 1989-1999).
3494). However, when molded articles obtained from conventional rubber-reinforced resin compositions containing diorganopolysiloxane are painted, they have the drawback of repelling paint and causing coating defects, and cannot be used in fields that require painting. As a result of intensive research to solve the above-mentioned drawbacks, the present inventors discovered that a rubber-reinforced resin composition containing a diorganopolysiloxane having a hydroxyl group and/or an amino group can be coated without repelling paint. Based on this knowledge, we have completed the present invention. That is, the present invention provides a rubbery polymer containing (a) an aromatic vinyl monomer, or (a) an aromatic vinyl monomer and (b) a vinyl cyanide monomer, an acrylic acid ester monomer, or a methacrylic acid monomer. A rubber-reinforced resin composition containing a graft polymer obtained by graft copolymerization of a monomer mixture consisting of at least one selected from ester monomers. polysiloxane
The object of the present invention is to provide an impact-resistant rubber-reinforced resin composition for coating, characterized in that it contains 0.01 to 0.3 parts by weight. The rubber reinforced resin composition used in the present invention is
A so-called ABS resin consisting of conjugated diene rubber, aromatic vinyl monomer, and cyanide vinyl monomer,
So-called ethylene/propylene rubber, aromatic vinyl monomer, and cyanide vinyl monomer components.
AES resin, acrylic rubber - aromatic vinyl monomer - vinyl cyanide monomer components
These include AAS resin, conjugated diene rubber, and so-called high-impact polystyrene resin consisting of an aromatic vinyl monomer component. Further, the diorganopolysiloxane having a hydroxy group and/or an amino group used in the present invention has the general formula It is an organofunctional diorganopolysiloxane having hydroxyl groups and/or amino groups as functional end groups. In the formula, R, R'=lower alkyl or phenyl group, 10≦n≦1000. In the present invention, the amount of organic functional diorganopolysiloxane added is determined based on the rubber reinforced resin composition.
0.01-0.3% by weight is suitable. If the amount added is less than 0.01% by weight, the impact strength will not be improved sufficiently, and if it is more than 0.3% by weight, it will adversely affect the paintability. The diorganopolysiloxane having hydroxy groups and/or amino groups used in the present invention can be added at any stage of producing the rubber reinforced resin composition, but is usually added to the powder of the rubber reinforced resin composition. After uniformly mixing using a Henschel mixer, form into pellets. At this time, a more useful molded product can be obtained by mixing a lubricant, an antioxidant, etc. at the same time as necessary. Next, examples of the present invention will be shown. Note that parts and % in the examples indicate parts by weight and % by weight, respectively. Example 1 ABS resin (JSR ABS 12A) with terminal-CH 2 OH
Organofunctional dimethylpolysiloxane having groups (OH group content 1.8%) was added in the proportions shown in Table 1, mixed in a Henschel mixer, pelletized in an extruder, and pelletized at a cylinder temperature of 220°C.
A test piece with a thickness of 6.4 mm for the Izotsu impact strength test and a test piece for the coating test with a thickness of 1.6 mm, a width of 55 mm, and a length of 80 mm were molded. As a comparative example, dimethylpolysiloxane was added in the same manner and a sample was molded. In the coating test, a paint (Planet AH - manufactured by Origin Electric Co., Ltd.) was spray-painted on a specimen and visually judged. The results are shown in Table-1.
