Title:
COMPOSITE MATERIAL WITH REDUCED DETERIORATION OF PASTE STATE
Document Type and Number:
WIPO Patent Application WO/2016/017581
Kind Code:
A1
Abstract:
The present invention provides a method for producing a composite material that comprises a silane-treated filler, a polymerizable monomer, and a polymerization initiator, said method being characterized by the sequential performance of the mixed polymerizable monomer preparation step, the mixed polymerizable monomer storage step, and the composite material production step that are described below. The mixed polymerizable monomer preparation step is a step in which the polymerizable monomer and the polymerization initiator are mixed in order to prepare a mixed polymerizable monomer. The mixed polymerizable monomer storage step is a step in which 1 to 50 liters of the mixed polymerizable monomer prepared in the mixed polymerizable monomer preparation step are stored under conditions that conform to a storage temperature of 1 to 23 °C and a storage period of 10 days to 1.5 years. The composite material production step is a step in which the mixed polymerizable monomer and the silane-treated filler are mixed in order to produce the composite material.
