Embodiment approach

[0042] Hereinafter, the present invention will be described in more detail with reference to examples. However, these examples are only for illustrating the present invention, and the scope of the present invention is not limited thereto. In these examples, the following methods were used to evaluate the physical properties of the samples.

[0043] hardness

[0044] Based on ASTM D2240, the measuring needle of the hardness tester (type A) is completely pressed on a certain point of the sample for 5 seconds, and then the hardness of the sample is measured. The hardness test was carried out at three points of each sample, and then the average value thereof was obtained. The hardness is used as an index to express the plasticizing efficiency.

[0045] Tensile Strength, Elongation, Modulus of Elasticity at 100% Elongation

[0046] Based on the ASTM D412 method, UTM was used to measure the tensile strength and elastic modulus of the samples. The tensile strength and modulus...

Embodiment 1

[0050] Preparation of Ester Plasticizers Using 1,4-Cyclohexanedimethanol, Benzoic Acid and 2-Ethylhexanoic Acid

[0051] First, 1.0 mol of 1,4-cyclohexanedimethanol, 0.6 mol of benzoic acid, 1.2 mol of 2-ethylhexanoic acid, 200 g of toluene (as a solvent) and 3.0 g of sodium bisulfate (as a catalyst) were placed in a A 2L round bottom flask with a stirrer and a condenser, then heated to 100°C, and reacted for 12 hours.

[0052] After the reaction, the pressure was reduced to 5 mmHg with a vacuum pump at 200° C., the unreacted organic acid was neutralized with a 10% by weight aqueous sodium carbonate solution, washed with water, dehydrated, and then filtered with an adsorbent to obtain a plasticizer composition. The plasticizer composition was found to comprise 4-(2-ethyl-hexanoyloxymethyl)-cyclohexylmethyl ester conforming to Formula 1 (about 50% by weight) as a main component.

[0053] Preparation of polyvinyl chloride resin composition

[0054] Test specimens were prep...

Embodiment 2

[0057] An ester plasticizer and a polyvinyl chloride resin composition were prepared in the same manner as in Example 1 except that capric acid was used instead of 2-ethylhexanoic acid. The test results are shown in Table 1 below.

Abstract

This invention relates to diol-ester based plasticiser compound, particularly to plasticisers for polyvinyl chloride (PVC), and plastics containing the same. More specifically, this invention relates to plasticisers prepared by esterification reaction of a diol with an organic acid. By using the plasticiser according to the present invention in the manufacture of polyvinyl chloride resin, product having high plasticisation efficiency and improved physical property such as hardness and tensile strength, etc., can be obtained.

Description

technical field [0001] The present invention relates to ester compounds and plastics containing the compounds, in particular to plasticizers for polyvinyl chloride (PVC) resins. More specifically, the present invention relates to ester plasticizers prepared by esterification of diols with carboxylic acids, through which plasticizers having high plasticizing efficiency and improved physical properties can be produced. (such as hardness, tensile strength, etc.) polyvinyl chloride resin composition. Background technique [0002] Polyvinyl chloride resin is a homopolymer of polyvinyl chloride or a copolymer containing more than 50% polyvinyl chloride. It is a commonly used resin, and it can be formed into various products through extrusion molding, injection molding, calendering and other processes. Such polyvinyl chloride resins are widely used as raw materials for various products such as pipes, wires, electric appliances, toys, films, sheets, synthetic leather, tar canvas, t...
