Continuous automatic production system and method for component B of two-component silicone adhesive

Abstract

The invention provides a continuous automatic production system for a component B of a two-component silicone adhesive. The continuous automatic production system comprises a high-speed dispersion machine, a vacuum additive tank and a metering and mixing unit, the metering and mixing unit comprises multiple sections of metering and mixing assemblies which are connected in sequence, each metering and mixing assembly comprises a first metering cylinder, a second metering cylinder and a mixer, and the base material inlet end of the mixer of the later section of metering and mixing assembly is connected with the discharging port end of the mixer of the previous section through the first metering cylinder; and a base material inlet end of the mixer of the first section of metering and mixing assembly is connected with a discharge hole of the high-speed dispersion machine through a metering cylinder I; and an auxiliary agent inlet end of the mixer of each section of metering and mixing assembly is connected with a discharge hole end of the vacuum auxiliary agent tank through a metering cylinder II. According to the invention, through the design of the segmented metering and mixing units, the continuous and uninterrupted mixing of the component B base material and the component B auxiliary agent is completed, the continuous and automatic production of the component B of the two-component silicone adhesive is realized, and compared with the traditional intermittent production, a large amount of intermediate ring time is saved, and the production efficiency is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of glue production for construction, and in particular relates to a continuous automatic production system and method for component B of two-component silicone glue. Background technique [0002] At present, the curing type of two-component silicone adhesive is mainly condensation type, which is widely used in the bonding and caulking of building curtain walls, the second sealing of insulating glass, etc. The two-component silicone sealant is composed of A and B components. A component contains basic polymers and fillers, and B component is composed of fillers, crosslinking agents, coupling agents, catalysts and other additives. Mix components A and B evenly in a specific ratio, and use it in the gaps of various substrates to play the role of bonding and sealing. After fully curing, it has high and low temperature resistance, aging resistance, high strength, high modulus, good elasticity, etc. advantage. D...

Problems solved by technology

[0004] This kind of method is intermittent production, with complicated steps, low production efficiency, and great pollution to the production environment. At the same time, it is easy to come into contact with air and dust during production and transfer, which will affect the quality and appearance, and there is a lot of waste during transfer.
