Problems solved by technology

[0005] In view of this, one of the purposes of the present invention is to provide a resin composition, which uses BOZ and amine-modified BMI to further react, and well exerts the performance advantages of the two high-performance resins of BMI / BOZ, overcoming the existing A series of problems in the application of BMI in the field of copper clad laminates, such as the high cost of the BT system, high technical difficulty or harsh curing conditions for the allyl-modified BMI system, or the existing BOZ / epoxy (EP) system, do not use The amount of BMI or BMI is small, the Tg is low, the mechanical properties are insufficient, the expansion coefficient is relatively large, and the dielectric properties are relatively high, so that the obtained resin composition has high Tg, high peel strength and elastic modulus. High temperature retention, low CTE, low water absorption, low dielectric loss, good heat resistance, heat resistance and flame retardancy, etc.

[0059] (2) Preparation of resin composition

[0060] Add benzoxazine resin, optional epoxy resin, optional toughening agent, optional curing agent, optional curing accelerator and solvent into a beaker of appropriate capacity in sequence, and stir at high speed to dissolve for 30-60 After dissolving, add amine-modified BMI, optional flame retardant and optional filler, stir for 2 hours to mature, and the solid content and solution viscosity of the resin composition are adjusted by the amount of solvent.

[0061] (3) Production of prepreg

[0062] The prepreg is made by heating and drying the above-mentioned resin composition, and it uses non-woven fabric or other fabrics as the base material, such as natural fibers, organic synthetic fibers and inorganic fibers. Use the above-mentioned resin composition, pre-impregnated fabrics such as glass cloth or organic fabrics, and finally pass the glass cloth through the nip shaft of rolling to remove part of the liquid resin, control ...

[0066] (1) Preparation of amine-modified BMI

[0067] Diaminodiphenylmethane (DDM) and 3,3'-dimethyl-5,5'-diethyl-4,4'-diphenylmethane bismaleimide (BMI) B239 by weight Feed at 1:10 (molar ratio is about 1:4.5), add it into a three-necked flask, then add an appropriate amount of dimethylacetamide (DMAc) solvent to stir and disperse, blow nitrogen, gradually increase the temperature while stirring to further dissolve, and put The temperature is kept at 100-115 degrees, refluxed for 2-4 hours, and then cooled to obtain a DDM-modified BMI, and the solid content of the DDM-modified BMI solution is controlled to 60% by the amount of solvent used.

[0068] (2) Preparation of resin composition

[0069]Feeding according to the material dosage ratio (solid weight) in Table 1 (except for the solvent, it refers to the solid dosage, including DDM modified B239), the specific preparation method is: add DDM modified B23928 parts, D12515 parts, PS to a 1000ml beaker in turn -63135 parts, N...

Embodiment 2

[0075] Example 2, Example 3 and Example 4 were prepared by repeating Example 1 respectively, the main difference being that the epoxy resin was respectively replaced by HP-7200H, NC-7300L, EPR627, wherein Example 2 and Example 4 also added XZ -92741, the preparation of other steps is substantially the same as in Implementation 1.

Abstract

The invention belongs to the technical field of copper clad laminates and particularly relates to a resin composition, prepreg using the resin composition and a laminate. The resin composition contains the ingredients in percentage by weight: 15-55% of amine modified bismaleimide (BMI), 10-45% of benzoxazine resin and 0-75% of epoxy resin. According to the resin composition, through further reaction of benzoxazine (BOZ) and amine modified bismaleimide (BMI), performance advantages of two kinds of high-performance resin, namely BMI and BOZ, are excellently exerted, so that the prepreg and the copper clad laminates, manufactured from the resin composition, have the properties of high Tg, relatively high peeling strength, relatively low CTE, relatively low water absorbing capacity, relatively low dielectric loss, relatively high elastic modulus high-temperature retention rate, relatively good resistance to hot and damp and the like, and reach a flame-retardant level UL94-V0.

Description

technical field [0001] The invention belongs to the technical field of copper-clad laminates, and in particular relates to a resin composition and a prepreg, a laminate and a printed circuit board using the resin composition. Background technique [0002] BMI is currently widely used in BT copper clad laminates for high-end packaging, but BMI in BT resins generally cannot directly react with cyanate (CE) resins, requiring special manufacturing processes, which is very difficult. At present, the manufacturing and market supply of BT copper clad laminates in the world are mainly monopolized by a few Japanese companies. In addition, the cost of CE is high, and the supply of CE market with special structure is limited, which greatly limits the application and technology development of BMI, and also limits the packaging. Further development of technology and industry. [0003] BMI system copper clad laminates modified by allyl compounds such as allyl bisphenol A, due to the intr...
