Sealant additive online adding device and method

Abstract

The invention provides a sealant additive online adding device. The sealant additive online adding device comprises a material conveying pipeline, a reaction cylinder, a mixing device, a superchargingdevice, a condensing unit, a buffer device, a filling machine, a metering device and an additive storage tank, wherein the reaction cylinder, the mixing device, the supercharging device, the condensing unit, the buffer device and the filling machine are sequentially arranged on the material conveying pipeline; the mixing device is further provided with an additive feed port; a discharge port of the metering device is connected with the additive feed port of the mixing device; a discharge port of the additive storage tank is connected with a feed port of the metering device; and the mixing device is a multi-component mixing machine. Compared with the prior art, the provided device is sequentially provided with the reaction cylinder, the mixing device, the supercharging device, the condensing unit, the buffer device and the filling machine on the material conveying pipeline, the high temperature filling is avoided, the guarantee period of a product is prolonged, the energy consumption is reduced; moreover, an additive is added online, so that the additive is stably mixed with a base stock, the quality fluctuation of the product is small, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of sealant production, and more specifically relates to a device and method for adding sealant additives online. Background technique [0002] Sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of cohesion. It is an adhesive used to fill the gap in the configuration to play a sealing role. Sealant can be divided into three categories: elastic sealant, liquid gasket and sealing putty, which have the functions of anti-leakage, waterproof, anti-vibration, sound insulation, heat insulation, etc., and are widely used in construction, transportation, electronic instruments and components of the seal. [0003] At present, the production of sealant is usually based on asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber and other dry or non-drying viscous substances, combined with talcum powder, clay, carbon...

Problems solved by technology

[0004] However, on the one hand, the high-speed disperser will generate high-speed friction on the material during stirring and dispersing, thereby generating a large amount of heat and heating up the material. Although cooling water is passed during the stirring process, the cooling is only heat transfer from the wall of the kettle to the inside, and the cooling effect Not very ideal, the time to stir a kettle is about 2 hours, the power consumption is about 120kw, and the high temperature filling will also cause the problem of short product warranty period; on the other hand, since the additives are added in batches, the adequacy of the stirring Difficult to detect, so the quality of each batch of products fluctuates greatly and the production efficiency is low
