Fire resistant paper machine oils

Abstract

A fire resistant paper machine oil comprising a blend of oil soluble base and water insoluble base having the formula: 0-100 wt % Oil Soluble PAG (Polyalkylene Glycol); 0-100 wt % Polyol Ester; an anti-wear additive; rust inhibitor; hindered phenolic anti-oxidant; alkylated di phenyl amine anti-oxidant; and, foam inhibitor. A blend of the base oils are the most preferred embodiment, however, a product could be formulated using only one type of base material such as an oil soluble base or a water insoluble base.

What is claimed is: 
     
         1 . A fire resistant paper machine oil comprising a blend of oil soluble base and water insoluble base. 
     
     
         2 . A fire resistant paper machine oil, comprising:
 a base comprising oil soluble Polyalkylene Glycol or Polyol Ester or a blend thereof;   an anti-wear additive;   a rust inhibitor;   an anti-oxidant; and;   a foam inhibitor.   
     
     
         3 . The fire resistant paper machine oil of  claim 2  wherein said anti-wear additive is selected from a group consisting of T-Butyl Phenyl Phosphate and amine phosphate or a mixture thereof 
     
     
         4 . The fire resistant paper machine oil of  claim 2  wherein said rust inhibitor is selected from the group consisting of sulfonate, metallic salt, calcium, zinc, and barium. 
     
     
         5 . The fire resistant paper machine oil of  claim 2  wherein said anti-oxidant is an alkylated di phenyl amine. 
     
     
         6 . The fire resistant paper machine oil of  claim 2  wherein said foam inhibitor is silicon based. 
     
     
         7 . A fire resistant paper machine oil, comprising
 Oil Soluble Polyalkylene Glycol ISO 15-680 grades;   Polyol Ester,   0.4 wt % T-Butyl Phenyl Phosphate;   0.5 wt % rust inhibitor;   0.3 wt % Hindered phenolic anti-oxidant;   0.75 wt % Alkylated di phenyl amine anti-oxidant;   0.02 wt % Foam inhibitor.   
     
     
         8 . The fire resistant paper machine oil of  claim 7  wherein the oil soluble PAG is 0 wt %-100 wt %. 
     
     
         9 . The fire resistant paper machine oil of  claim 7  wherein said Polyol Ester is 0 wt %-100 wt %. 
     
     
         10 . The fire resistant paper machine oil of  claim 7  wherein said Polyol Ester is ISO 68 grade. 
     
     
         11 . The fire resistant paper machine oil of  claim 7  wherein said rust inhibitor is selected from the group consisting of sulfonate, metallic salt, calcium, zinc, and barium. 
     
     
         12 . The fire resistant paper machine oil of  claim 7  wherein said rust inhibitor has a TBN of 0-50. 
     
     
         13 . The fire resistant paper machine oil of  claim 7  wherein said Hindered phenolic anti-oxidant has a CAS 125643-61-0. 
     
     
         14 . The fire resistant paper machine oil of  claim 7  wherein said Alkylated di phenyl amine anti-oxidant has a CAS 68411-46-1. 
     
     
         15 . The fire resistant paper machine oil of  claim 7  wherein said foam inhibitor is silicon.
