Static mixer of silicone sealant and method thereof for preparing silicone sealant

Abstract

The invention discloses a static mixer of a silicone sealant and a method thereof for preparing the silicone sealant. The mixer comprises a container for storing a first material, a container for storing a second material, a static mixer and a separation mechanism, wherein the separation mechanism is connected with the static mixer; the container for storing the first material is connected with afirst pump; the first pump is connected with a first metering cylinder which is internally provided with a first piston; a first metering cavity is formed among the front end of the first piston, an inlet and an outlet; the container for storing the second material is connected with a second pump; the second pump is connected with a second metering cylinder which is internally provided with a second piston; a second metering cavity is formed among the front end of the second piston, the inlet and the outlet; the ratio of the diameter square of the first metering cavity to the diameter square of the second metering cavity is equal to the volume proportion of the first material to the second material; and the backs of the first piston and the second piston are provided with an extrusion oilcylinder and a synchronous extrusion mechanism. The mixer has the advantages of simple and reasonable structure, convenient operation and low maintenance cost.

Description

(1) Technical field [0001] The invention discloses a silicone sealant static mixer and a method for preparing silicone sealant, in particular to a silicone sealant static mixer for automatic synchronous quantitative mixing of materials, and automatic synchronous quantitative mixing of materials and continuous preparation The silicone sealant method. (2) Background technology [0002] Most of the one-component silicone sealants are cured by moisture, so they are required to be produced under sealed and vacuum conditions. The traditional production methods and equipment are planetary mixers, single-cylinder intermittent production, and various components are added during the production process. Auxiliaries and color pastes, because they are all manually operated, there are inevitable errors, and because they are produced in a single cylinder, they must be exposed to air when they are discharged, which is more likely to cause unstable quality. In addition, the material cylinder...

[0002] Most of the one-component silicone sealants are cured by moisture, so they are required to be produced under sealed and vacuum conditions. The traditional production methods and equipment are planetary mixers, single-cylinder intermittent production, and various components are added during the production process. Auxiliaries and color pastes, because they are all manually operated, there are inevitable errors, and because they are produced in a single cylinder, they must be exposed to air when they are discharged, which is more likely to cause unstable quality. In addition, the material cylinder and agitator need to be cleaned, which causes material loss, pollute the environment
