Problems solved by technology

Therefore, some people use block fillers such as talc as lubricants to improve processability, but the effect is not obvious, and the addition of these block fillers further deteriorates the interlayer adhesion.
In addition, in order to improve the drilling processability, metal molybdenum compounds are added, metal molybdenum compounds such as zinc molybdate are added to the thermosetting resin composition to improve processability, and molybdenum compound particles are supported on talc, etc., which exists in the layer of laminated boards. The problem of the obvious reduction of the adhesive force between them, and the dispersibility of this type of molybdenum compound in the resin is poor, the density is also high, and it is prone to sedimentation, and satisfactory results cannot be obtained.

Abstract

The invention discloses a thermosetting resin composition and application thereof. The thermosetting resin composition contains thermosetting resin and inorganic filler, and the inorganic filler is subjected to wrapping treatment by molybdenum alkene disulfide; and on the basis of the total mass of the thermosetting resin composition, the content of the inorganic filler is 10wt%-80wt%. According to the provided thermosetting resin composition, the molybdenum alkene disulfide wraps the inorganic filler, the compatibility of the inorganic filler and a resin system can be improved effectively, and the resin composition which is uniform and stable in dispersion can be obtained without complicated dispersing equipment. Provided prepreg is prepared by dipping the thermosetting resin compositionin a reinforcing material and then drying the thermosetting resin composition, problems about dispersion and settling of a molybdenum compound are solved effectively, and the molybdenum compound can be uniformly distributed in the prepreg. A provided laminated board contains at least one prepreg; and a provided printed circuit board contains at least one prepreg.

Description

technical field [0001] The invention relates to a thermosetting resin composition and its application. Background technique [0002] Printed circuit boards have begun to develop rapidly in the direction of high precision, high density, high performance, microporosity, thinning and multi-layering, and their application range is becoming wider and wider, and the substrate material determines the printed circuit board to a large extent. performance of the circuit board. At present, in order to reduce the thermal expansion coefficient of laminates, resins with low thermal expansion coefficients are usually selected or the content of inorganic fillers is increased. However, the low thermal expansion coefficient resin has a special structure and high cost; and the method of increasing the content of inorganic filler can not only effectively reduce the thermal expansion coefficient of the compound, but also greatly reduce the cost. However, highly filled resins will significantly...
