Abstract

The invention belongs to the technical field of composite material processing, and particularly relates to a hydrolyzable polymer, which has the following structural formula: a first fragment, a second fragment and a third fragment are respectively selected from one of an alkyl chain, an aromatic part and a polyether chain, are different from one another and are randomly arranged, and the first fragment, the second fragment and the third fragment are different from one another and are different from one another. Wherein a, b and c are integers between 0 and 10 and are not 0 at the same time, m and n are integers between 1 and 3, and m + n is less than or equal to 4. The invention has the following beneficial effects: the raw material cost is low, the problem of poor stability of common treatment agents is solved, the precipitation phenomenon of conventional hydrolyzable series dispersants or silane coupling agents is serious in the use process, precipitation of a large amount of organic matters on the surface of a mixture can be observed within 24 hours, and the treatment effect is good. The hydrolyzable polymer can prolong the stability period of the composite material to 1-6 months, so that the storage stability and the production efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of composite material processing, and in particular relates to a hydrolyzable polymer and an epoxy resin heat-conducting material composition containing the polymer. Background technique [0002] The arrival of the 5G era has provided many conveniences to people's lives, but with the increasing integration of electronic components, the performance requirements for materials have become more stringent, and the application of composite materials has become more extensive. Epoxy resin and polyurethane resin composite materials are widely used in many fields. In order to improve the expected performance of the material, it is the most effective and common practice to increase the amount of fillers, such as thermally conductive adhesives, thermally conductive gaskets, thermally conductive gels, and conductive adhesives. , conductive gaskets, electromagnetic shielding materials, PCB board composite materials, fire...
