Initiator composition, unsaturated polyester resin composition comprising same, and method for curing resin

摘要

An initiator composition, including: at least two compounds represented by the chemical formula of R—CO—O—O—CO—R and a compound represented by the chemical formula of R1—CO—O—O—R2, where R represents a C2-C12 alkyl or a C6-C10 aryl or substituted aryl, R1 represents a C1-C10 alkyl or a C6-C10 aryl, and R2 represents a C1-C10 alkyl.

1. An initiator composition for expediting the curing of an unsaturated polyester resin at room temperature, the initiator composition comprising:
at least two diacyl peroxides; and a carboxylic ester peroxide;wherein:
the two diacyl peroxides are selected from the group consisting of benzoyl peroxide, 2,4-dichlorobenzene acyl peroxide, lauroyl peroxide, and diacetyl peroxide; and the carboxylic ester peroxide is selected from the group consisting of tert-butyl peroxybenzoate (TBPB), tert-butyl peroxy diethyl acetate, and t-butyl peroctoate (TBPO).
