Binder for heat-insulating silencing pipe and using method of binder

Abstract

The invention discloses a binder for a heat-insulating silencing pipe and a using method of the binder. The binder comprises 10-15 parts of type III polypropylene, 20-23 parts of heat-resistant polyethylene, 1-3 parts of maleic anhydride, 2-6 parts of silicon dioxide, 10-38 parts of epoxy resin, 1-5 parts of propylbutadienyl triethoxysilane, 8-26 parts of a curing agent, 2-3 parts of boron trinitride ethylamine, 2-2.5 parts of a polysulfide rubber flexibilizer, 5-25 parts of olefine acid resin, 10-41 parts of a heat conducting agent, 1-3 parts of an accelerator and 5-12 parts of a regulator. The curing agent is used for improving the curing effect, absorbed heat can be rapidly dispersed through the heat conducting agent, and then the crosslinking speed and viscosity of the binder are improved through the accelerant and the regulator, so that the binder is easier to use; therefore, the product has good heat resistance and is not easy to burn and fall off, so that a hush pipe bonded by using the binder can stably work in a high-temperature environment, and the problem that the hush effect of the hush pipe in the high-temperature environment is reduced due to poor thermal stability ofan existing binder is solved.

Description

Technical field [0001] The present invention relates to the field of binders, and more particularly to a binder for insulating silencers and methods thereof. Background technique [0002] During the water discharge process, since the amount of water flow is too large, the flow rate is too fast, resulting in a large noise, thereby causing a bad impact on the surrounding environment, so the sound absorbing tube is required to drain, the soundproofing tube is generally checked by the inside of the pipe. Composition, the insulation layer is also required outside when working in a high temperature environment, which is mainly connected by an adhesive, but the existing binder thermal stability is not good, so that the sound insulation layer is easily detached, thereby causing the silence tube Reduce the silence effect in a high temperature environment. Inventive content [0003] It is an object of the present invention to provide an adhesive of a heat insulating silence tube and a met...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an adhesive for heat-insulating and sound-absorbing pipes and its use method, aiming to solve the problem that the thermal stability of existing adhesives is not good enough to reduce the sound-absorbing effect of sound-absorbing pipes in high-temperature environments
