| titleOfInvention | Resin paste for prepreg, prepreg and preparation method and application thereof |
| abstract | The invention relates to the field of molding compounds, and provides a resin paste for a prepreg, the prepreg, a preparation method and an application thereof, wherein the resin paste for the prepreg comprises the following components in parts by mass: 100 parts of a resin system; 0.9-1.8 parts of an initiator; 2-5 parts of an internal release agent; 0-50 parts of a filler; 1-3 parts of a thickening agent; 0.2-0.4 part of a stabilizer; 0.5-3 parts of a dispersing agent; the resin system comprises unsaturated polyester resin and a low-shrinkage additive, wherein the mass ratio of the unsaturated polyester resin to the low-shrinkage additive is 1-2: 1. The invention also provides a preparation method of the prepreg, after the glass fiber cloth is impregnated with the resin paste, the glass fiber cloth impregnated with the resin paste is sealed by adopting a wrapping material, and then thickening treatment is carried out, so that the high-strength prepreg can be obtained, can be used together with sheet molding compounds, and improves the strength of a molded product. |
