Problems solved by technology

From the point of view of the preparation process, more waste water is generated
[0004] In addition, with the gradual development of the application of aralkylphenol resins, further requirements have been put forward for the performance improvement of aralkylphenol resins. Its service life; and in the application of ultra-thin copper-clad laminates, it is necessary to improve the toughness and the bending resistance of the resin while improving the heat resistance, which puts forward new requirements for the aralkylphenol resin. Generally, in the design of the formula, it is considered to add rubber or carboxyl-terminated rubber, but on the one hand, the addition of rubber will reduce the heat resistance of the composite system while improving the toughness. Generally, it is modified by adding a heterocyclic phosphorus system. But the problem is compatibility; in addition, when the copper clad laminate is incinerated, due to the pollution caused by the introduction of phosphorus, it is introduced into the copper clad laminate system to improve the heat resistance and improve the toughness to a certain extent. The addition of the

Abstract

The invention discloses aralkyl phenol resin and a preparation method thereof. The preparation method comprises the steps that under the condition of an acid catalyst, phenol reacts with dicyclopentadiene or methyl dicyclopentadiene, then alkylphenol is added, the temperature is increased, benzyl halide is dropwise added for a reaction, finally, a terminating agent is added, the mixture is heated to a certain temperature, and redundant phenol and small molecular substances in the system are removed to obtain the aralkyl phenol resin. The softening point of the aralkyl phenol resin prepared by the method is 50-140 DEG C; dicyclopentadiene or methyl dicyclopentadiene is introduced into the resin, so that the heat resistance of the resin is improved, and intramolecular toughening is realized by introducing a C4-C20 alkyl chain or olefin chain. The invention also discloses an application of the aralkyl phenol resin in the fields of electronic packaging materials and epoxy plastic packaging.

Description

technical field [0001] The invention belongs to the field of organic synthesis, and in particular relates to a synthesis method and application of an aralkylphenol resin. Background technique [0002] Phenol aralkyl resins are generally prepared from phenol and aralkyl ethers or aralkyl alcohols as a resin with a multi-aromatic ring structure in the main chain. Compared with ordinary phenol-formaldehyde resins, the main chain contains The multi-aromatic ring structure makes the phenol aralkyl resin have good heat resistance and heat and humidity resistance. It can be widely used in electronics, aviation, machinery and other fields. It is an important raw material for production; at the same time, it can also be used as a high-end epoxy resin Resin curing agent, to improve the heat resistance and other properties of epoxy resin, to broaden the application of epoxy resin. At the same time, it can also react with epichlorohydrin to prepare epoxy resin, which is an important ra...
