| titleOfInvention | A preparation method of Fv0 grade flame-retardant paper-based copper-clad laminate |
| abstract | The invention belongs to the technical field of copper-clad laminate production, and in particular relates to a method for preparing a flame-retardant paper-based copper-clad laminate with a flame-retardant grade of Fv 0. Phenol, epoxy soybean oil and amine catalysts are sequentially put into a reactor, and reacted at high temperature. , then formaldehyde and nitrogen-containing phenolic resin are put into the reaction kettle to obtain epoxy soybean oil modified phenolic resin, and the impregnated resin obtained by adding organic flame retardant is dip-coated on wood pulp paper to obtain impregnated tablet. The flame-retardant paper-based copper-clad laminates are made by superimposing the sheets, and the flame-retardant reaches Fv 0 level. The present invention adopts epoxidized soybean oil to replace tung oil, the product quality is stable and the price is low, the nitrogen content in the nitrogen-containing phenolic resin is increased, and the nitrogen-phosphorus synergistic flame-retardant effect of the copper-clad laminate is improved, thereby reducing the formation of tetrabromobisphenol A in flame-retardant dioxin, saving and environmental protection; the quality of the plate produced by the invention is improved, and it has the advantages of low water absorption, better punching property, better solder resistance, etc., and has a better appearance color. |
