Synthetic example 1

[0118] Synthesis Example 1: Synthesis of diallyl 1,2-cyclohexanedicarboxylate (crosslinking agent)

[0119] 170.5 g (2.93 mol) of allyl alcohol, 150.1 g (1.63 mol) of toluene, 241.1 g (1.40 mol) of 1,2-cyclohexanedicarboxylic acid, and 7.18 g of dodecylbenzenesulfonic acid were put into a 500 mL flask (0.022mol), stirred with a magnetic stirrer, and refluxed with an oil bath. After 20 hours, the heat was turned off and the flask was cooled. The obtained reaction solution was neutralized and washed with water, the low-boiling components were distilled off with a rotary evaporator, and the obtained concentrated solution was subjected to vacuum distillation to obtain the target diallyl 1,2-cyclohexanedicarboxylate 110.6g. The obtained compound 1 was used in Examples.

Abstract

The purpose of the present invention is to provide a thermosetting resin composition which does not cause environmental issues such as VOC and has excellent curability (in particular, curability at low temperatures) comparable to the case in which a diallyl phthalate monomer is used as a crosslinking agent. A thermosetting resin composition of the present invention is characterized by containing:an unsaturated polyester resin; an alicyclic polyfunctional allyl ester represented by formula (1) (in the formula, n represents an integer of 2-4, and Z is an n-valent alicyclic hydrocarbon group); one kind of initiator selected from the group consisting of peroxy ketals, peroxy esters, dialkyl peroxides, and peroxy carbonates, and having a one-minute half-life temperature in the range of 100-250DEG C and a molecular weight of 100-400 has excellent curability at low temperatures.

Description

technical field [0001] This invention relates to a thermosetting resin composition. Background technique [0002] Recently, sealing resins are being used for electronic components such as capacitors, coils, and resistors for the purpose of improving reliability and productivity. The properties sought as sealing resins vary depending on the shape and size of electronic components, but examples of physical properties include moisture resistance, low stress, high thermal conductivity, impact resistance, and the like. As resins satisfying these properties, thermosetting resins such as diallyl phthalate resins and unsaturated polyester resins are used. [0003] Resin compositions such as known unsaturated polyester resin compositions and vinyl ester resin compositions generally use styrene having excellent reactivity as a crosslinking agent (see Patent Document 1). However, since there are environmental problems such as marine pollution, volatile organic compounds (VOC), and st...
