Abstract

The invention discloses a cyanate resin raw material composition and cyanate resin and a cyanate resin metal composite material and a preparation method thereof. The cyanate resin raw material composition comprises, based on 100 parts by weight, 40-89.5 parts by weight of cyanate monomer material, 10-50 parts by weight of short glass fiber, 0.01-0.1 part by weight of catalyst, and 0.2-10 parts byweight of liquid promoter, wherein the short glass fiber contains a boron element, and on the basis of 100 parts by weight of the short glass fiber, the content of the boron element is 15 parts by weight or above based on B2O3. The use of the cyanate resin raw material composition is beneficial for increasing the bonding force between a resin material and a metal material in the resin metal composite material.

Description

technical field [0001] The invention relates to the field of resin metal production, in particular to a cyanate resin raw material composition, cyanate resin and cyanate resin metal composite material and a preparation method thereof. Background technique [0002] It is a well-known fact in the industry that the material of metal alloy is smoother, flatter and less wear-resistant. Based on the aforementioned characteristics, in order to make the metal can be used to prepare the casing of electronic products, it is usually necessary to inject resin on the surface of the metal material to form a resin layer to protect the surface of the metal material. [0003] In the existing solutions, the metal material is usually subjected to high-temperature aqueous solution corrosion, electrochemical corrosion, and high-temperature water washing, and then the thermosetting material is injected on the surface of the metal material, so that the thermosetting material and the metal material...
