Transparent composite material composition and method of preparing transparent composite material using the same

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.

What is claimed is: 
     
         1 . A transparent composite material composition, comprising, based on a total amount of the transparent composite material composition:
 90% to 99% by weight of a thermosetting urethane acrylate resin; and   1% to 10% by weight of an organic hydroperoxide initiator.   
     
     
         2 . The transparent composite material composition according to  claim 1 , wherein the thermosetting urethane acrylate resin is at least one resin selected from the group consisting of aromatic urethane acrylate, aromatic urethane diacrylate, aromatic urethane multiacrylate, halogen-substituted urethane acrylate, and sulfur (S)-containing urethane acrylate. 
     
     
         3 . The transparent composite material composition 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. 
     
     
         4 . A weight-reduced transparent composite material prepared by a method of preparing a transparent composite material, wherein the method comprises:
 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.   
     
     
         5 . A molded transparent window product for automobiles made of a weight-reduced transparent composite material prepared by a method of preparing a transparent composite material, wherein the method comprises:
 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.
