Polyvinyl chloride resin plasticiser
View Patent ↗The invention relates to a diol-ester based plasticizer prepared by reacting a diol and a carboxylic acid for use with a polyvinyl chloride resin composition to impart improved physical properties, such as hardness and tensile strength.
1. An ester plasticizer, represented by Formula 1 below:
wherein R is (CH 2 ) n is an integer of 0 to 2, R 1 is a substituted or unsubstituted alkyl group of 4 to 16 carbon atoms, and R 2 is a substituted or unsubstituted naphthenic group or aryl group of 5 to 10 carbon atoms.
2. The ester plasticizer according to claim 1 , wherein R 1 is a substituted or unsubstituted alkyl group of 6 to 10 carbon atoms, and R 2 is a substituted or unsubstituted naphthenic group or aryl group of 5 to 8 carbon atoms.
3. The ester plasticizer according to claim 1 , wherein R 1 and R 2 each independently are substituted by a straight-chain or branched-chain alkyl group of 4 to 20 carbon atoms, an alkenyl group of 4 to 20 carbon atoms, a cycloalkyl group of 4 to 20 carbon atoms or an aryl group of 6 to 10 carbon atoms.
4. An ester plasticizer composition, comprising the ester plasticizer of claim 1 in an amount of 50˜100 wt %.
5. The ester plasticizer composition according to claim 4 , further comprising at least one of compounds represented by Formulae 2 and 3 below in an amount of less than 50 wt % based on the total amount of the ester plasticizer composition:
wherein R is (CH 2 ) n , n is an integer of 0 to 2, R 3 and R 4 are each independently a substituted or unsubstituted alkyl group of 4 to 16 carbon atoms, and R 5 and R 6 are each independently a substituted or unsubstituted cycloparaffin or aryl group of 6 to 10 carbon atoms.
6. The ester plasticizer composition according to claim 5 , wherein R 3 to R 6 each independently are substituted by a straight-chain or branched-chain alkyl group of 4 to 20 carbon atoms, an alkenyl group of 4 to 20 carbon atoms, a cycloalkyl group of 4 to 20 carbon atoms or an aryl group of 6 to 10 carbon atoms.
7. A polyvinyl chloride resin composition, comprising the ester plasticizer composition of claim 4 in an amount of 10˜100 phr based on a polyvinyl chloride resin.
8. A polyvinyl chloride resin composition comprising the ester plasticizer composition of claim 5 in an amount of 10˜100 phr based on a polyvinyl chloride resin.
9. A polyvinyl chloride resin composition comprising the ester plasticizer composition of claim 6 in an amount of 10˜100 phr based on a polyvinyl.
10. The polyvinyl chloride resin composition according to claim 7 , further comprising additives, excluding filler and pigment, up to 30 phr based on a polyvinyl chloride resin.
11. The ester plasticizer according to claim 2 , wherein R 1 and R 2 each independently are substituted by a straight-chain or branched-chain alkyl group of 4 to 20 carbon atoms, an alkenyl group of 4 to 20 carbon atoms, a cycloalkyl group of 4 to 20 carbon atoms or an aryl group of 6 to 10 carbon atoms.
