Abstract

The invention discloses a production method of an unsaturated polyester emulsion binder for chopped strand mats, which is characterized by comprising the following steps of: putting 55-70 percent of unsaturated polyester resin, 10-15 percent of acetone and 20-30 percent of reactive emulsifier in percent by weight in a high-speed dispersion machine for evenly stirring and mixing; then adding deionized water until the system generates phase inversion; keeping stirring for a while and then adding the deionized water for dilution to obtain an unsaturated polyester emulsion with a certain concentration, wherein the reactive emulsifier is a polymerizable emulsifier which contains double bonds and can participate in reaction. The production method of the unsaturated polyester emulsion binder is simple and easy to operate; the produced unsaturated polyester binder has smaller grain size, good stability, strong binding power and high penetration velocity in cinnamene, thereby being very suitable for preparing glass fibre chopped strand mats.

Description

(1) Technical field [0001] The invention relates to a production method of an unsaturated polyester emulsion, in particular to a production method of an unsaturated polyester emulsion binder for chopped strand mats.
