Problems solved by technology

[0007] Bismaleimide triazine resin (BT resin) of Mitsubishi Gas can be said to be a model for the application of bismaleimide and cyanate ester. Although it has successfully solved the problem of water absorption in the application of bismaleimide resin, And the patented technology has been disclosed, but its key technical points are still difficult for domestic technicians to grasp
Amines are epoxy resin curing agents. After the amine reacts with the epoxy resin, the epoxy resin ring-opens to produce a large number of hydroxyl groups, and the hydroxyl groups will reduce the ring-opening temperature of the benzoxazine resin and accelerate the opening of the benzoxazine. Ring reaction, so that a large number of hydroxyl groups and amino groups are rapidly generated in the system, which leads to the acceleration of the curing reaction of the entire system and narrows the rheological window

Synthetic example 1

[0070] In a 500ml three-neck flask equipped with a stirrer, a reflux condenser and a thermometer, place it in an oil bath, add bisphenol A: 91.2g, p-phenylenediamine: 94.4g, formaldehyde: 48.0g; then add 80ml of ethanol and 20ml of toluene was used as a solvent, and the temperature was slowly raised to 75° C. and kept for 3 hours. During the process, the stirring state was kept continuously, and nitrogen was bubbled into the three-necked flask for protection. Above-mentioned reaction finishes, and after the product is cooled to room temperature, keep stirring and dropwise add methanol solution in the flask, to no longer having precipitate to separate out, stop stirring, leave standstill 24hr under room temperature, filter supernatant liquid, collect precipitate, will The precipitate was placed in a vacuum drying oven at 50°C and dried for 5 hours to obtain a diamine containing a benzoxazine structure, which was designated as N(BOZ)-1.

Synthetic example 2

[0072]In a 500ml three-neck flask equipped with a stirrer, a reflux condenser and a thermometer, place it in an oil bath, add bisphenol F: 79.2g, p-phenylenediamine: 94.4g, formaldehyde: 48.0g; then add 80ml of ethanol and 20ml of toluene was used as a solvent, and the temperature was slowly raised to 60° C. and kept for 5 hours. During the process, the stirring state was continuously maintained, and nitrogen was bubbled into the three-necked flask for protection. Above-mentioned reaction finishes, and after the product is cooled to room temperature, keep stirring and dropwise add methanol solution in the flask, to no longer having precipitate to separate out, stop stirring, leave standstill 24hr under room temperature, filter supernatant liquid, collect precipitate, will The precipitate was placed in a vacuum drying oven at 50°C and dried for 5 hours to obtain a diamine containing a benzoxazine structure, which was designated as N(BOZ)-2.

Abstract

The invention discloses a resin composition comprises, by 100 parts of solid weight, 40-99 parts of diamine modified bismaleimide resin containing a benzoxazine structure and 10-60 parts of epoxy resin. Bismaleimide and diamine resin containing benzoxazine are enabled to pre-react first at low temperature, and benzoxazine is almost not in ring opening at the low temperature; a part of reaction groups are consumed through pre-reaction to form prepolymer with certain molecular weight, so that steric hindrance of benzoxazine ring-opening reaction is increased, reaction rate of the benzoxazine structure in resin structure is slowed down, a rheolytic reaction window of the resin composition is adjusted well, and a risk that the resin composition has the defect that dried flowers or white stripes appear on a base material due to the fact that reaction is too fast in the process of press-fitting is lowered.

Description

technical field [0001] The invention relates to a resin composition and a prepreg and a metal foil laminate made by using the resin composition, which belong to the technical field of electronic materials. Background technique [0002] The advancement of electronic technology is changing with each passing day. Portability and thinning have become the direction that electronic complete products have been pursuing. However, the thinning and thinning of complete electronic products requires the preparation of electronic products, including printed circuit boards, to be thinner. Therefore, it is necessary to The base material of copper clad laminate has high rigidity and anti-warping ability, so as to meet the structural support and processing requirements of printed circuit boards. [0003] In the prior art, the material prepared from the thermosetting resin composition with epoxy resin and its curing agent as essential components has the advantages of good heat resistance, ins...
