Problems solved by technology

For example, Chinese invention patent 201010270929.8 discloses a method of preparing flame-retardant resin by reacting DOPO with BMI and allyl compounds, which has a good flame-retardant effect, but the storage stability of the prepolymer and the toughness of the cured product Still need to improve
In addition, Chinese invention patent 201110239153.8 discloses a halogen-free phosphorus-containing flame-retardant polyimide resin composition and its preparation method, which is obtained by a one-step reaction, which improves the storage stability of the resin composition and the toughness of the cured product , but the added bisphenol A epoxy resin itself has extremely low heat resistance, resulting in a reduction in the heat resistance of the obtained bismaleimide resin composition

Abstract

The invention discloses a halogen-free flame-retardant polyimide resin composition, comprising, by weight, bismaleimide a, composite allyl compound b, and phosphorous compound c. A preparing method of the halogen-free flame-retardant polyimide resin composition includes: heating the bismaleimide, the composite allyl compound and the phosphorous compound in a reaction flask for reaction, with the composite allyl compound being composed of first allyl compound and second allyl compound. The first allyl compound is made from one or any of diallyl bisphenol A, diallyl bisphenol S, allyl phenoxy resin, and diallyl diphenyl ether. The second allyl compound is made from one or any of diallyl bisphenol A diglycidyl ether, diallyl bisphenol S diglycidyl ether, diallyl diphenyl ether diglycidyl ether. A laminate made from the halogen-free flame-retardant polyimide resin composition has the advantages of high resistance, high toughness, low water absorption rate, and excellent dielectric property and flame retardance.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and relates to a halogen-free flame-retardant polyimide resin composition and a prepreg and a laminate made by using the composition. Background technique [0002] With the development of high-functionality, high-performance, high-reliability and environmental protection of electronic components, the heat resistance of the plate must be improved to meet the harsh processing technology of lead-free soldering and multiple pressing. The traditional FR-4 The heat resistance of the material is far from meeting the requirements. [0003] Bismaleimide resin is a kind of compound with dual active end groups, which can be cross-linked and cured under the action of heating or catalyst, and has excellent heat resistance, heat and humidity resistance, dielectric properties, good mechanical properties and Dimensional stability, so it is widely used in many high-tech fields such as aerospace, ele...
