Abstract

A transparent composite material composition, comprises, based on a total amount of the transparent composite material: 90 to 99% by weight of a thermosetting urethane acrylate resin; and 1 to 10% by weight of an organic hydroperoxide initiator. Such a transparent composite material composition exhibits superior properties such as superior transparency, impact resistance, scratch resistance, and weather resistance while realizing weight reduction.

First claim

What is claimed is:

1. A method of preparing a transparent composite material, the method comprising:
preparing a thermosetting urethane acrylate resin;
preparing a transparent composite material composition, based on a total amount of the transparent composite material composition, by adding 1% to 10% by weight of an organic hydroperoxide initiator to 90% to 99% by weight of the thermosetting urethane acrylate resin; and
hardening and molding the transparent composite material composition,
wherein the thermosetting urethane acrylate resin is a halogen-substituted urethane acrylate resin.

2. The method according to claim 1 , wherein the organic hydroperoxide initiator is at least one selected from the group consisting of perbutyl peroxide, di-t-butyl peroxide, t-butylcumyl peroxide, dicumyl peroxide, di-(2,4-dichlorobenzoyl)-peroxide, dibenzoyl peroxide, di(2-tert-butylperoxyisopropyl)benzene, t-butyl peroxybenzoate, 1,1-di-(t-butylperoxy)-3,3,5-trimethylcyclohexane, and 2,5-dimethyl-2,5di(t-butylperoxy)-hexane.

3. The method according to claim 1 , wherein the hardening is carried out by heating to 45 to 95° C.

4. The method according to claim 1 , wherein the hardening is carried out through UV irradiation.
