Description
Technical field
The present invention relates to Casting Technology field more particularly to a kind of furan resin casting reinforcing agent and its preparation sides
Method.
Background technology
Reinforcing agent is also known as coupling agent, and there are two different reactive groups in structure, and one is the bases of close inorganic matter
Group X (such as methoxyl group, ethyoxyl), can be hydrolyzed reaction and generate silicone hydroxyl (Si-OH), with the keys such as glass, silica
It closes；Another kind is organophilic group Y (such as vinyl, amino), can be with interpolymer interaction.Furane resins are as viscous
Agent is tied, an important indicator of performance is the intensity of resin sand.Mainly there are two aspects for the raising of mechanical strength of resin：First, passing through
Production technology is adjusted, the intensity of resin itself is improved；Second is that it is strong to reach reinforced resin that reinforcing agent such as silane coupling agent etc. is added
The purpose of degree.The structure feature of silane coupling agent make it have by inorganic matter (such as sand) and organic matter (such as synthetic resin) this two
The ability that the material that kind property differs greatly combines.
