Title:
POLYVINYL CHLORIDE LOW-TEMPERATURE TOUGHENING MODIFIER AND POLYVINYL CHLORIDE COMPOSITION CONTAINING LOW-TEMPERATURE TOUGHENING MODIFIER
Document Type and Number:
WIPO Patent Application WO/2017/182003
Kind Code:
A1
Abstract:
Disclosed in the present invention are a polyvinyl chloride low-temperature toughening modifier and a polyvinyl chloride composition containing the low-temperature toughening modifier. The low-temperature toughening modifier is rubber powder of which the elongation at break is 1000% to 1600%, the Shore hardness is greater than 53.0 HA and the tensile strength is greater than 9.0 MPa. The polyvinyl chloride composition comprises the following raw material components in parts by weight: (a) 100 parts of polyvinyl chloride resin; (b) 1 to 30 parts of low-temperature toughening modifier; (c) 0.5 to 5 parts of stabilizer; (d) 0 to 50 parts of filler; (e) 0 to 50 parts of wood flour; (f) 0 to 10 parts of acrylate polymer; (g) 0 to 20 parts of anti-impact modifier; (h) 0 to 5 parts of lubricant; and (i) 0 to 10 parts of pigment. By modifying PVC by using the low-temperature toughening modifier, the elongation at break of a PVC hard product can be greatly improved without affecting the hardness and the tensile strength of the PVC.
