[Example 68] [Title of the Invention] A process of formation of heat insulator and the mixing gun [Claims] 1. A process to form flame resistant insulation into a space between two surfaces by injection of a compound composed of synthetic high molecular weight foaming particles, synthetic high molecular weight latex binding agent and organic bromine-containing compound to give flame resistibility to the bound synthetic high molecular weight foaming particles. 2. A mixing gun with an aspirating chamber (4) with a high-pressure gas nozzle (3) connected an injection pipe (1) at its front-end, an aspirating pipe (6) to aspirate the foaming agent attached to branch out near the a high-pressure gas nozzle (3) of the injection chamber (4) and the injection chamber (5) to contain the latex binder and the flame retardant. [Excerpt from Detail Description of the Invention and Drawings] This invention concerns insulation where heat resistively is desired in the spaces between two surfaces such as those in a building. Foaming polystyrene beads are appropriate for building space insulation because they form a foam structure. Because they have very low volume density and free liquidity, however, they are difficult to confine within the space and prevent it from running out of gaps and damaged area. The solution to this problem to be solved effected by the inventor is to cover the foaming polystyrene beads with synthetic high molecular weight latex binder. By this process, the said latex binder prevents movement of foaming polystyrene beads, and leakage of foaming polystyrene beads through openings is prevented. Further uniqueness of this invention is that the proportion of synthetic high molecular weight foaming particles to latex binder and flame retardant can be controlled and the mixture is sent into the desired space by a nozzle (2) of the mixing gun. In the mixing gun, the high molecular weight foaming particles are mixed with the mixture of the latex binder and the flame retardant near the nozzle (2) of the injection chamber (1) and is immediately injected out into the space through the nozzle (2). Thus, even if a long tubing is used to place the mixture into the space, the mixture will not build up on the inside of the tubing enabling continuous even placement in the space. Furthermore, the said gun can be used to apply other mixtures such as noise dampening or water proofing material into the inter-wall spaces of a building by applying first an adhesive. Figure 2 114
Figure 1 [Explanation] The related invention (Claim 2), the mixing gun, can be used for processes other than the process of the specified invention (Claim 1), but is appropriate for that of the specified invention. The mixing gun of the related invention is directly used equipment for working the process of the specified invention. [Concerned Section] Patent Law Section 37(iv) 115
