Abstract

A fire retardant antistatic coating and coated substrate. The coating includes a mixture of a radiation curable halogenated prepolymer, an effective amount of a quarternary ammonium compound antistatic agent and an effective amount of an antimony pentoxide flame ratardant agent. A coated substrate having a substrate film material coated with the above coating is included. A method for making a fire resistant and antistatic film which includes the steps of: (a) providing a substrate film; (b) preparing the coating by mixing a radiation curable prepolymer with an effective amount of a quarternary ammonium antistatic compound and an effective amount of an antimony pentoxide fire retardant compound; (c) the coating is then applied to the film material; and (d) the coating is contacted with electron radiation in an amount sufficient to cure the coating.

Claims

1. A method of making a fire resistant and antistatic film comprising the steps of:

(a) providing a substrate film material;

(b) preparing a flame retardant antistatic coating by mixing a radiation curable halogenated prepolymer with an effective amount of a quaternary ammonium antistatic compound and an effective amount of an antimony pentoxide fire retardant compound;

(c) applying said coating to said film material; and

(d) contacting said coating with electron radiation in an amount sufficient to cure said coating.

2. The method of making a fire resistant and antistatic film of claim 1 wherein said antimony pentoxide fire retardant compound further comprises a colloidal dispersion of an antimony pentoxide in a suitable resin vehicle.

3. The method of making a fire resistant and antistatic film of claim 2 wherein said resin vehicle is a polyester resin.

4. The method of making a fire resistant and antistatic film of claim 3 wherein said colloidal dispersion comprises about 40 parts of said antimony pentoxide in about 60 parts of said polyester resin vehicle.

5. The method of making a fire resistant and antistatic film according to claim 2 wherein said antimony pentoxide is particulate in form having a particle size in the range of from about 0.015 microns to about 0.030 microns.

6. The method of making a fire resistant and antistatic film according to claim 2 wherein said chlorinated oligomer is a diallyl chlorendate and said brominated oligomer is a diacrylate ester of the diglycidyl ether of tetrabromo bis-phenol A.

7. The method of making a fire resistant and antistatic film according to claim 1 wherein said prepolymer is selected from the group of chlorinated oligomer, a brominated oligomer and mixtures thereof.

8. The method of making a fire resistant and antistatic film according to claim 1 wherein said prepolymer further comprises the mixture of a chlorinated oligomer and a brominated oligomer.
