Technical field
The invention belongs to rubber gloves field, more particularly to a kind of fluorine ether/fluorine silicon compounded rubber gloves and its preparation side
Method.
Background technology
Rubber gloves is widely used in the social every field such as hospital, family, electron trade, food service industry, gardening plantation,
Primarily serve isolation pollution, the effect of protection both hands.If traditional rubber gloves is divided into the different of raw materials used-sizing material
Dry kind, such as:Emgloves, with Heveatex as primary raw material;Butyronitrile gloves, with by butadiene and acrylonitrile Jing emulsion polymerization
Into artificial synthesized latex be primary raw material;Butylbenzene gloves, with by the artificial synthesized of butadiene and styrene emulsion polymerization
Latex is primary raw material.
Fluorosioloxane rubber is to apply most common fluorine silicon systems row new material so far.Because fluorine is the most strong element of electronegativity, its
The C-F key quite stables connected into carbon atom, heat resistance is also higher.Fluorine element is introduced into siloxanes, not only with silica
The superior heat resistance of alkane, weatherability, hydrophobicity and demoulding, and the waterproof with fluorochemical, oil resistant and solvent resistance
Etc. performance.Therefore, fluorosioloxane rubber can be used in -60-200 DEG C of temperature province and excellent with oil resistant, solvent resistance etc.
