Problems solved by technology

However, this method requires the addition of a certain amount of organic resin raw materials, so the upper limit of the filling ratio of the filler to the entire composition is limited, and it may not be possible to say that the thermal conductivity of the obtained resin (cross-linked product) is sufficient.

Abstract

The purpose of the present invention is to provide a light- or heat-curing method whereby a cured material (crosslinked material / resin) can be obtained even when a large amount of a filler is included, and to provide a curable resin composition used in the curing method. The present invention relates to a light- or heat-curing method and a curable resin composition used in the curing method, the curing method including: a step 1 for obtaining a condensate having Si-O-Al and / or Si-O-Si constituent units, obtained from a silane derived from a silane coupling agent having a mercapto group and aluminum derived from (E) an aluminum alkoxide, from (A) a compound comprising a salt of a carboxylic acid and an amine and having a carbonyl group for generating a radical and a carboxylate group for decarboxylating and generating a base by light irradiation or heating, (B) an aluminum alkoxide, (C) a silane coupling agent having a mercapto group, and (D) water; and a step 2 for reacting the condensate (E), (H) a compound having two or more polymerizable unsaturated groups, and (I) a filler under a condition of light irradiation or heating.

Description

technical field [0001] The present invention relates to a light or thermal curing method for obtaining a cured product (crosslinked product / resin) containing a filler, a curable resin composition used in the curing method, and the like. Background technique [0002] With the increasing demand for high-power LED devices for lighting applications, electronic devices represented by PCs and tablet terminals that process high-speed and large-capacity information, and power semiconductors that control motors in electric vehicles or hybrid vehicles, etc. With higher performance and higher density, the heat generated from components becomes a problem. The generated heat has problems such as having a great influence on the performance and life of the product. How to efficiently dissipate the generated heat without sacrificing product performance such as miniaturization / lightweight / thinness has become an issue. [0003] In general, metals and ceramics are examples of materials with ...
