Abstract
(EN)
Provided is an aqueous resin composition which contains a plasticizer (D) and in which a composite resin (ABC) obtained through binding between, through a silicon-oxygen bond, a polysiloxane segment (C) derived from a condensate (c) of an alkyltrialkoxysilane having an alkyl group having 1-3 carbon atoms, and a polysiloxane segment (B) of a composite resin (AB) obtained through chemical binding of a polymer segment (A) having a neutralized acidic group and the polysiloxane segment (B), is dissolved or dispersed in an aqueous medium. The aqueous resin composition is characterized in that the total contained proportion of the polysiloxane segment (B) and the polysiloxane segment (C) in the composite resin (ABC) is 15-85 mass%. The aqueous resin composition can be used to form a coating film having excellent coating film appearance, adhesion to a base material, hot water resistance, solvent resistance, weather resistance, antifouling properties, and followability to a base material, and therefore, is suitable for a coating agent.
(FR)
L'invention concerne une composition de résine aqueuse qui contient un plastifiant (D) et dans laquelle une résine composite (ABC) obtenue par liaison, par l'intermédiaire d'une liaison silicium-oxygène, entre un segment polysiloxane (C) issu d'un condensat (c) d'un alkyltrialcoxysilane comprenant un groupe alkyle comportant 1 à 3 atomes de carbone, et un segment polysiloxane (B) d'une résine composite (AB) obtenue par liaison chimique d'un segment polymère (A) comportant un groupe acide neutralisé et du segment polysiloxane (B), est dissoute ou dispersée dans un milieu aqueux. La composition de résine aqueuse est caractérisée en ce que la proportion totale de segment polysiloxane (B) et de segment polysiloxane (C) présente dans la résine composite (ABC) varie de 15 à 85 % en masse. La composition de résine aqueuse peut être utilisée pour former un film de revêtement présentant un très bel aspect de film de revêtement, une remarquable adhérence à un matériau de base, une très grande résistance à l'eau chaude, aux solvants et aux intempéries, d'excellentes propriétés antisalissure et une remarquable adaptabilité à un matériau de base, et est, par conséquent, appropriée pour former un agent de revêtement.

中和された酸基を有する重合体セグメント(A)及びポリシロキサンセグメント(B)が化学結合した複合樹脂(AB)のポリシロキサンセグメント(B)と、アルキル基の炭素原子数が1~3のアルキルトリアルコキシシランの縮合物(c)由来のポリシロキサンセグメント(C)とが珪素-酸素結合を介して結合している複合樹脂(ABC)が水性媒体中に溶解又は分散し、さらに可塑剤(D)を含有している水性樹脂組成物であり、前記複合樹脂(ABC)中の前記ポリシロキサンセグメント(B)及び前記ポリシロキサンセグメント(C)の合計の含有比率が15~85質量%であることを特徴とする水性樹脂組成物を提供する。この水性樹脂組成物は、塗膜外観、基材密着性、耐温水性、耐溶剤性、耐候性、耐汚染性、及び基材追従性に優れた塗膜を形成可能であることから、コーティング剤に好適に用いることができる。
