Problems solved by technology

[0002] With the vigorous development of wireless transmission products and the leap forward of high-frequency transmission technology, higher requirements are placed on the dielectric properties of materials. The existing materials of epoxy resin and phenolic resin system can no longer meet advanced applications, especially Meet the requirements of high-frequency printed circuit boards
Fluorine-based resins are used as substrate materials for printed circuit boards with low dielectric loss, but such resins are expensive and difficult to process, and their applications are limited to military and aerospace fields
In addition, polyphenylene ether resin has good mechanical properties and excellent dielectric properties, and has increasingly become the preferred resin material for high-frequency printed circuit board substrates. However, at present, polyphenylene ether with double bonds is used to manufacture high-frequency and high-speed boards. Through the free radical reaction, special production equipment must be used, and the shelf life of the prepreg is short, the production process conditions are difficult to adjust, and the cost is high
[0003] CN101684191B proposes to use benzoxazine, styrene-maleic anhydride, and phosphorus-containing curing agent to compound and cure epoxy resin to obtain a cured product with lower dielectric constant and dielectric loss, but only with styrene-maleic anhydride When acid anhydride is used to reduce the dielectric properties of materials, there will inevitably be many other problems, especially the impact on adhesion, because the non-polar styrene structural unit in the molecular structure of styrene-maleic anhydride (SMA) reduces Modification of the polarity of the matrix resin weakens the interaction between the resin and the copper foil; at the same time, because a large number of benzene ring structures in SMA increase the brittleness of the resin cross-linked network, it also affects the bonding performance under dynamic conditions. Detrimentally affects the bonding strength between substrates and between substrates and copper foil
[0004] CN100523081C proposes to use benzoxazine, styrene-maleic anhydride and other curing agents to compound and cure phosphorus-containing and halogen-free and phosphorus-free epoxy compositions to obtain a cured product with lower dielectric constant and dielectric loss, but Using phosphorus-containing epoxy resin as the main resin, although it can achieve excellent flame retardancy, too much introduction of phosphorus will inevitably have a great impact on the water absorption of the substrate, which will inevitably have a negative impact on many other properties of the board
[0007] At present, for improving the properties of thermosetting epoxy resin compositions, most of the research focuses on the selection of curing agent or toughening agent to improve the properties of the resin composition, but for improving the performance of the composition through the selection and modification of the main resin components. rarely reported

Abstract

The invention provides a thermosetting alkyl polyol glycidyl ether resin composition and application thereof. The resin composition is prepared by using epoxy resin as a main resin component, wherein the epoxy resin comprises alkyl polyol glycidyl ether which is 50-100 percent of mass of the main resin component. The composition is used for preparing prepregs, laminated boards, printed circuit boards and the like. Since the epoxy resin having an alkyl polyol glycidyl ether molecular structure is adopted as a main resin component, a prepared laminated board has relatively good thermal performance and adhesive performance, and has the advantages of low dielectric performance, low preparation cost, simple method and wide application prospect.
