Coating composition and vehicle interior material

Abstract

A coating composition comprising 100 pbw as solids of a synthetic resin emulsion and 1-300 pbw of a non-halogen flame retardant in which P and N-containing non-halogen flame retardant particles are surface coated with hydrophobic inorganic oxide fine particles is applicable to vehicle interior materials.

1 . A coating composition comprising 
 100 parts by weight as solids of a synthetic resin emulsion and    1 to 300 parts by weight of at least one non-halogen flame retardant in which phosphorus and nitrogen-containing non-halogen flame retardant particles are surface coated with hydrophobic inorganic oxide fine particles.    
   
   
       2 . The coating composition of  claim 1 , wherein said synthetic resin emulsion is selected from the group consisting of (meth)acrylate resin base emulsions, styrene/acrylate copolymer base emulsions, urethane resin base emulsions, ethylene/vinyl acetate copolymer base emulsions, rubber base emulsions, and mixtures thereof.  
   
   
       3 . The coating composition of  claim 1 , wherein the particulate phosphorus and nitrogen-containing non-halogen flame retardant is selected from the group consisting of guanidine phosphate, ammonium phosphate, melamine phosphate, ammonium polyphosphate, melamine-surface-treated ammonium polyphosphate, silicon compound-surface-treated ammonium polyphosphate, and mixtures thereof.  
   
   
       4 . The coating composition of  claim 3 , wherein the particulate phosphorus and nitrogen-containing non-halogen flame retardant is ammonium polyphosphate.  
   
   
       5 . The coating composition of  claim 3 , wherein the particulate phosphorus and nitrogen-containing non-halogen flame retardant is silicon compound-surface-treated ammonium polyphosphate.  
   
   
       6 . The coating composition of  claim 1 , wherein the hydrophobic inorganic oxide fine particles are hydrophobic silica fine particles.  
   
   
       7 . The coating composition of  claim 1 , wherein the coated non-halogen flame retardant has an average particle size of 3 to 35 μm.  
   
   
       8 . The coating composition of  claim 1 , wherein the hydrophobic inorganic oxide fine particles have an average particle size of 0.001 to 5 μm.  
   
   
       9 . A vehicle interior material coated with the composition of  claim 1.
