| titleOfInvention | Black low-flow-mark polyester molding compound and preparation method thereof |
| abstract | The invention discloses a black low-flow-mark polyester molding compound which is prepared from mixed materials of, by weight: 65-80% of resin paste and 20-35% of alkali-free short chopped fiberglass. The resin paste is composed of raw materials of, by weight: 50-70 parts of unsaturated polyester resin, 30-50 parts of a black polyvinyl acetate solution, 1-1.5 parts of a curing agent, 2-4 parts of a mold release agent, 150-200 parts of a filling material, and 0.8-1.2 parts of a thickening agent. According to the invention, a low-shrinkage agent solution is prepared from polyvinyl acetate with a black body, such a shrinkage is lower than 0.05%. More importantly, the color of the molding compound is realized by the black color of polyvinyl acetate rather than by adding a black pigment. Therefore, non-uniform color due to pigment agglomeration caused by phase separation is avoided. Also, no black pigment is adopted in the formula, such that an inductive effect of a black pigment upon the curing agent is avoided, and the polyester molding compound provided by the invention has a longer storage life than other black polyester molding compounds. |
