Problems solved by technology

Since DOTP is not a phthalate-based plasticizer, DOTP has no controversy about environmental hormones, but it has no advantages in terms of physical properties of wallpaper, and multiple problems have been found, such as Compatibility of raw material additives (stabilizers and viscosity reducers), deterioration of foaming performance when making wallpaper, rapid increase in viscosity in winter, etc.

Embodiment 1）

[0070] Based on 100 parts by weight of vinyl chloride resin (emulsion polymer resin with a degree of polymerization of 900), 60 parts by weight of diethylhexylcyclohexane as a plasticizer, 3 parts by weight of K / Zn-based composite stabilizer (KKZ102PF , Woochang Chem.Co.), 3 parts by weight of azodicarbonamide blowing agent (DWPX03, Dongjin Semichem), 5 parts by weight of ester-based viscosity reducer (V5125, BYK Corp.), 10 parts by weight of TiO 2 (R902, Dupont Corp.) and 100 parts by weight of calcium carbonate (OM-10, Omya Korea) having an average particle diameter of 10 μm were mixed in a Mathis mixer for 10 minutes to prepare a plastisol. Then, physical properties were evaluated by the above-mentioned measurement methods, and the results are shown in Table 2.

Embodiment 2）

[0072] Plastisol was prepared by the same method as in Example 1, except that 70 parts by weight of diethylhexylcyclohexane was used as a plasticizer. The results are shown in Table 2.

Embodiment 3）

[0074] Plastisol was prepared by the same method as in Example 1, except that 80 parts by weight of diethylhexylcyclohexane was used as a plasticizer. The results are shown in Table 2.

Abstract

The present invention relates to a vinyl chloride resin composition for wallpaper, comprising diethylhexylcyclohexane as a plasticizer. The diethylhexylcyclohexane of the present invention may replace controversial phthalate-based plasticizers and thus prevent environmental contamination. The vinyl chloride resin composition of the present invention uses the diethylhexylcyclohexane plasticizer, which has a much lower initial viscosity and lower temperature viscosity, and which exhibits many fewer changes as time elapses as compared to conventional phthalate-based plasticizers as well as to dioctyl terephthalate, which serves as an alternative to phthalate-based plasticizers, thus improving workability. The vinyl chloride resin composition of the present invention generates less volatile organic compounds than conventional compositions, and thus may be widely applied to eco-friendly products.

Description

technical field [0001] The present invention relates to a vinyl chloride resin composition, and more particularly, to an environmentally friendly vinyl chloride resin composition capable of minimizing the amount of generated volatile organic compounds (VOCs) to have high safety to the environment and without using Phthalate-based plasticizer. Background technique [0002] Vinyl chloride resin is an interpolymer containing vinyl chloride homopolymer and having a vinyl chloride content of more than 50%, and it is one of five main thermoplastic resins prepared by suspension polymerization and emulsion polymerization. Among them, polyvinyl chloride resin prepared by emulsion polymerization is mixed with plasticizer, stabilizer, filler, foaming agent, pigment, viscosity depressant, titanium dioxide (TiO 2 ) and sub-materials (sub-material) with specific functions are mixed, and are used in various fields in the form of plastisol by coating forming method or molding coating formi...
