Abstract

The invention discloses high-toughness high temperature-resistant modified unsaturated polyester resin. Raw materials of the high-toughness high temperature-resistant modified unsaturated polyester resin comprise maleic anhydride, m-phthalic anhydride, o-phthalic anhydride, ethyl acetate, methyl methacrylate, hydroxyhydroquinone, hydroquinone, dicyclopentadiene, cobalt naphthenate styrene, phosphate melamine, methyl ethyl ketone peroxide, dicumyl peroxide, a silane coupling agent KH-550, nano titanium dioxide, nano-silicon dioxide, nano-aluminium trihydrate, modified glass fibres, decabromodiphenyl ethane, silane microcapsule-coated ammonium polyphosphate, ethylene glycol, diethylene glycol and propylene glycol. The invention further provides a preparation method for the high-toughness high temperature-resistant modified unsaturated polyester resin. The unsaturated polyester resin prepared by the preparation method has excellent toughness and high temperature resistance.

Description

technical field [0001] The invention belongs to the technical field of unsaturated polyester resins, in particular to a modified unsaturated polyester resin with high toughness and high temperature resistance and a preparation method thereof. Background technique [0002] Unsaturated polyester resin refers to a type of polymer with a linear structure and a main chain with repeated ester bonds and unsaturated double bonds. It is generally formed by polycondensation of diols and unsaturated dibasic acids at high temperatures. UPR has been widely used in the fields of construction, shipbuilding, automobile industry, rail transit, electrical products, and light industrial products due to its good process performance, good overall performance of the cured resin, and low price. However, the resin is flammable and prone to fire, which has led to public questions about the safety of its products. [0003] The toughness and high temperature resistance of unsaturated resins in the pr...
