Title:
VINYL CHLORIDE RESIN AGGREGATE PARTICLE, METHOD FOR PRODUCING SAME, AND GLOVES COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2012/165021
Kind Code:
A1
Abstract:
The present invention provides: vinyl chloride resin aggregate particles which enable the production of a plastizol having excellent impermeability and good sagging properties; a method for producing the vinyl chloride resin aggregate particles; and gloves produced using the vinyl chloride resin aggregate particles. The vinyl chloride resin aggregate particles according to the present invention have a volume average particle diameter of 10-60 μm, wherein the content ratio of particles having particle diameters of 10-60 μm is 50 vol% or more, the moisture absorption rate is 1.5 wt% or less when being held under the conditions of a temperature of 30˚C and a relative humidity of 97.0 ± 0.4% for 24 hours, and a plastisol comprising 100 parts by weight of the vinyl chloride resin aggregate particles and 160 parts by weight of di-2-ethylhexyl phthalate fulfills the relationship represented by the formula 3 ≤ η70/η40 ≤ 1000. In the vinyl chloride resin aggregate particles according to the present invention, the number of voids each having a void size of 1.0 μm or more is less than 5.0 per one aggregate particle, and the content ratio of particles having particle diameters of 1.0 μm or less after being subjected to an ultrasonic treatment is less than 3.0 vol%.
