Problems solved by technology
A large number of studies have shown that although hydrocarbon resins can provide good dielectric properties, due to the flexibility and non-polar carbon chain structure of hydrocarbon resins, hydrocarbon resins have insufficient rigidity, low strength, and poor heat resistance after curing. However, there are still many problems to be solved in practical applications such as low transition temperature and poor adhesion.
For example, in the Chinese invention patent CN10544841B, a combination of hydrocarbon resin and allyl-modified phenolic resin is used to make printed circui...

Synthetic example 1
[0067] Put N-(4-hydroxyphenyl)maleimide (190g, 1mol), phenol (94g, 1mol, M94) and oxalic acid (10g) into the flask equipped with thermometer, condenser and stirrer, mix and stir After uniformity, put it in a constant temperature water bath at 70°C; then, under stirring, add formaldehyde solution (150mL, the ratio of phenol / aldehyde to 1 / 0.8) dropwise into the flask for 0.5 hours; after adding formaldehyde, maintain 70°C The temperature and stirring conditions were reacted for 15 hours; then, the reaction product was dissolved and diluted with 400mL acetone, and then the reaction product was precipitated with 40% methanol aqueous solution; the above dissolution-precipitation operation was repeated 3 to 5 times, and it was filtered, separated, Drying yielded pure maleimide phenolic formaldehyde (P-1).
[0068] Take 100g of maleimide phenolic novolac (P-1) prepared by the above method and 500g of methyl isobutyl ketone solvent and put them in a flask to fully mix and dissolve...

Abstract
The present invention discloses a thermosetting resin composition, which comprises (calculated as the solid weight): (a) 10-80 parts of a hydrocarbon resin, (b) 20-100 parts of maleimide ester, (c) 0.1-8 parts of an initiator, and (d) 5-100 parts of an epoxy resin. According to the present invention, the maleimide ester having the polyfunctional long-chain structure and the rigid imide ring is used and is matched with the hydrocarbon resin having the flexibility to form the thermosetting composition, such that the thermosetting resin composition and the prepared printed circuit prepreg and laminated plate produced by using thermosetting resin composition have characteristics of excellent dielectric property, excellent heat resistance, excellent adhesion, excellent flame retardancy, excellent flexural strength, excellent toughness, high peel strength, low water absorption, excellent processability and the like through the interaction between the hydrocarbon resin and the maleimide ester.
Description
technical field [0001] The invention relates to a thermosetting resin composition, a prepreg and a laminate made by using the composition, and belongs to the technical field of electronic materials. Background technique [0002] In recent years, with the continuous advancement of high-speed and high-frequency technologies for information processing and information transmission, higher and higher requirements have been put forward for printed circuit substrate materials in terms of dielectric properties. To put it simply, printed circuit substrate materials need to have lower dielectric constant and dielectric loss tangent to reduce signal delay, distortion and loss during high-speed transmission, as well as interference between signals. Therefore, expect to provide a kind of thermosetting resin composition, the printed circuit board material that uses this thermosetting resin composition to make can show sufficiently low low dielectric constant and low dielectric constant in...
