Solid silane coupling agent composition, process for producing the same, and resin composition containing the same
View Patent ↗It is an object of the present invention to provide a non-gelling solid silane coupling agent which enhances adhesion of a resin composition to metals and so forth when added to the resin composition, and which has excellent storage stability and molten fluidity. The present invention is a non-gelling, pulverizable, solid silane coupling agent composition composed of a reaction product of the following components. (A) 1 to 40 wt % of a silane coupling agent containing one or more functional groups from among a vinyl group, glycidyl group, styryl group, methacryl group, acryl group, ureido group, chloro alkyl group, mercapto group, and isocyanate group (B) 1 to 40 wt % of a silane coupling agent containing one or more functional groups from among an amino group, dimethylamino group, and imidazole group (C) 50 to 90 wt % of a phenol compound
1. A non-gelling, pulverizable solid silane coupling agent composition comprising a reaction product of the following components:
(A) 1 to 40 wt% of a silane coupling agent containing one or more functional groups selected from the group consisting of a vinyl group, glycidyl group, styryl group, methacryl group, acryl group, ureido group, chloro alkyl group, mercapto group, and isocyanate group;
(B) 1 to 40 wt% of a silane coupling agent containing one or more functional groups selected from the group consisting of an amino group, dimethylamino group, and imidazole group; and
(C) 50 to 90 wt% of a phenol compound.
2. A method for manufacturing a non-gelling, pulverizable, solid silane coupling agent composition, the method comprising:

drying the reaction product at 90 to 150° C.
3. A method for manufacturing a non-gelling, pulverizable, solid silane coupling agent composition, the method comprising:
adding the silane coupling agent (A) described in claim 1 , a mixed solution of the silane coupling agent (B) described in claim 1 and an alcohol to the phenol compound (C) described in claim 1 which has been melted by heating at 60 to 150° C.;
causing the resultant mixture to react at 60 to 150° C.; and
drying the reaction product at 90 to 150° C., whereby the silane coupling agent composition is obtained.
4. A non-gelling, pulverizable, solid silane coupling agent composition, obtained by causing the silane coupling agent (A), the silane coupling agent (B) and the phenol compound (C) described in claim 1 to react in the presence of an alcohol at 60 to 150° C., and then drying the reaction product at 90 to 150° C.
5. The non-gelling, pulverizable, solid silane coupling agent composition according to claim 1 , wherein the phenol compound (C) is a phenol resin.
