Continuous production method and device of acidic and neutral transparent sealing silicone adhesive

Abstract

The embodiment of the invention discloses a continuous production method and a continuous production device of acidic and neutral transparent sealing silicone adhesive and is used for effectively improving the product quality. The method disclosed by the embodiment of the invention comprises the following steps that firstly, in a first screw rod machine, 107 glue, first auxiliary agents, white oil and silicone oil are quantificationally fed for mixing, dispersion and vacuum pumping, and liquid materials are obtained after the temperature reduction of a cooler; the liquid materials are directly fed into a mixing device; white carbon black powder is metered through a metering tank; the metered white carbon black powder is conveyed to a mixing device through a powder conveying device and is mixed with the liquid materials, and mixed materials are obtained; and next, the mixed materials are conveyed to a second screw rod machine, and the product is obtained through preparation. The method and the device have the advantages that the white carbon black powder body is transported through the powder conveying device, the pressurization is not needed in the delivery process, the complicated step of pressurization is omitted, the equipment damage is avoided, and the yield is improved.

Description

technical field [0001] The invention relates to a production process of liquid silicone rubber, in particular to a continuous production method and device for acidic and neutral transparent sealing silicone rubber. Background technique [0002] Acidic and neutral transparent glue, widely used in construction, electronics, machinery, daily chemical industry and other fields. At present, the method of acidic and neutral transparent sealants produced in China is to use a stirred tank to mix, disperse, and heat polysiloxane polymer compounds (hereinafter referred to as 107 glue), additives, white oil, and silicone oil to make a base material, and then Put it in a planetary mixer or a powerful disperser in a material tank, add various materials such as white carbon black and additives, and then fully stir to produce a large barrel of glue, and then pack it into a sealed silicone glue through a sub-packaging equipment. [0003] see figure 1 , the specific production process incl...

AI Technical Summary

Problems solved by technology

[0004] Since the above method needs to use a special powder pressurizing device, the powder must be pressurized to enter the mixing and dispersing machine, the output of the mixing and dispersing machine is low, and the seal is easily damaged under pressure. tube) are vulnerable parts, and the reliability of equipment operation is poor

The products produced by the above methods are prone to skinning, which affects product quality
