Abstract

An acenaphthene-type polyphenyl copolymerized allyl phenolic active dilution resin and a preparation method thereof, relating to a resin and a preparation method thereof, the phenolic resin synthesized by the present invention reacts with allyl chloride to generate an allyl ether phenolic resin, and the resin is used in Claisen rearrangement reaction occurs at high temperature, and then allyl phenolic resin is generated; at the same temperature, acenaphthyl cyclopentadienone is added to undergo Diels-Alder reaction with allyl resin, and finally acenaphthyl polyphenyl copolymerized allyl The phenolic reactive diluting resin replaces the phenolic hydroxyl hydrogen in the phenolic resin with an allyl group, and the resulting resin has a relatively low viscosity, which can be used as a reactive diluting resin to reduce the resin viscosity. The acenaphthene-type polyphenyl condensed ring structure with larger molecular groups is introduced, and under specific conditions, Diels-Alder reaction occurs with the double bond in the allyl phenolic resin, and multiple benzene ring groups are introduced to make the synthesized resin It has high temperature resistance and thermo-oxidative stability.

Description

technical field

[0001] The invention relates to a resin and a preparation method thereof, in particular to an acenaphthene-type polyphenyl copolymerized allyl phenolic active dilution resin and a preparation method thereof. Background technique

[0002] Phenolic resin has been widely used as a high-performance thermosetting resin. However, during the curing process of phenolic resin, small molecular substances such as condensation water or ammonia are released, and pressure is often required during molding. Moreover, the formed phenolic resin material is brittle and has pores. , The performance is not high, thus hindering the high-performance development of phenolic resin materials.

[0003] The Chinese patent No. 200310113965.3 proposes to use chemical toughening method to manufacture closed-cell phenolic foam. The Chinese patent No. CN200710127849.5 uses cashew nut oil to modify phenolic resin to improve the toughness of phenolic resin and is used to prepare copper plates...
