Outline
A resin paste was prepared from vinyl resin, low shrinkage agent, powder, initiator, and polymerization inhibitor. The resin paste was used to impregnate continuous glass felt, then a polyester glass fiber felt board prepreg was obtained after curing, and a polyester glass fiber felt board was prepared by mould pressing and hot pressing. The preparation of resin, the selection of initiator system, and the pressing molding process were studied. The results show that with the increase of the thickness of polyester glass fiber felt board, it is more difficult to mold, and there are more internal defects in it. A high thickness polyester glass fiber felt board with grade 155(F) of heat resistance is obtained by using the self-prepared vinyl resin and carbon-carbon intermediate temperature initiator under 120-125℃ and 7.5 MPa, and the problems of pores and cracks in the high thickness polyester glass fiber felt board are solved at the same time.
