Device and method for preparing bi-component modified silicone sealant for prefabricated building

Abstract

The invention discloses a device and a method for preparing a bi-component modified silicone sealant for a prefabricated building, relates to the technical field of prefabricated buildings, and aims to solve the technical problems that the secondary mixing time is long, the same viscous raw material is not easy to fuse with other raw materials, the mixture has high adhesion, the mixture is not easy to discharge completely after falling down automatically, and the temporary retention amount is large. The mixing box is arranged at the output end of the primary mixing mechanism, the multiple raw material conveying pipes are arranged at the upper end of the primary mixing mechanism, the secondary mixing mechanism is arranged in the middle of the mixing box, the discharging mechanism is further arranged on the outer side of the mixing box, and the secondary mixing mechanism is in meshed connection with the discharging mechanism, so that the mixing uniformity of raw materials can be preliminarily improved; the materials can be extruded and mixed and can also be stirred and mixed, so that the materials are convenient to discharge and relatively clean to discharge.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a device and method for preparing a two-component modified silicone sealant for prefabricated buildings. Background technique [0002] A prefabricated building is a building assembled from prefabricated parts at the construction site, which is called a prefabricated building. According to the form and construction method of prefabricated components, it is divided into five types: block building, plate building, box building, skeleton plate building and rising plate building. [0003] Silicone sealant is a paste made of polydimethylsiloxane as the main raw material, supplemented by crosslinking agent, filler, plasticizer, coupling agent and catalyst in a vacuum state. With water in the air it should cure to form elastic silicone rubber. [0004] However, when the existing silicone sealant preparation device mixes the raw materials, the initial mixing is single, a...

Problems solved by technology

[0004] However, when the existing silicone sealant preparation device mixes the raw materials, the initial mixing is single, and there is no auxiliary full mixing, which leads to a long secondary mixing time. The raw materials are stirred and mixed, because the silicone sealant is gelatinous. Yes, when stirring and mixing, the same viscous raw materials are not easy to fuse with other raw materials. Since the mixture is jelly, the adhesion is relatively high, it will not be easy to discharge when it falls automatically, and the temporary retention is large.
