Hemp insulation fire retardant applicator and method

Abstract

A device and a method for applying a liquid fire retardant onto hemp fibers and into hemp insulation batting using a multiple needle construction, which can act as an insulation substitute to be used in building structures that does not irritate the skin or contain harmful, toxic elements and is a quicker and a more efficient method with a reduction in drying time.

What is claimed is: 
     
         1 . A device for delivering a liquid fire retardant onto and into the fibers of hemp insulation batting comprising:
 a) a pressure pump connected to a container containing a liquid fire retardant;   b) a base holding a plurality of injection needles, the injection needles having one or more exit holes for delivering the liquid fire retardant and are held in place by a ridged base in a fixed relationship;   c) at least one of tubing and conduit connected to both the container and the plurality of injection needles for delivering the liquid fire retardant from the container to the injection needles; and   d) a valve for opening and closing the connection between the container and the injection needles.   
     
     
         2 . The device for delivering a liquid fire retardant onto and into the fibers of hemp insulation batting according to  claim 1  wherein the fire retardant is selected from the group comprising boratic acid and sodium borate. 
     
     
         3 . The device for delivering a liquid fire retardant onto and into the fibers of hemp insulation batting according to  claim 1  wherein the pressure pump creates a pressure from about 10-120 psi.
