A kind of water-based styrene-butadiene latex production device and production method

Abstract

A water-based styrene-butadiene latex production device and production method belong to the technical field of styrene-butadiene latex. In order to solve the problem that the traditional water-based styrene-butadiene latex production device is not convenient for rapid production of small sample fluids with the same concentration during preparation, the traditional water-based styrene-butadiene latex The problem that the production device is inconvenient to measure softened water; the present invention intercepts a certain amount of raw material when feeding the raw material into the first stirring inner cavity, and intercepts a certain amount of softened water through the inclined pipe, and the two are mixed by small stirring The paddle is used to stir, and a small dose of sample is first made to observe its concentration. When the softened water enters the water inner shell through the water inlet pipe, a part of the water is reserved first through the structure of the pressure sensing plate, the folded water pipe and the jacking column, and then released. , through the setting of the equalizing tank and the corresponding tank, the demineralized water can be quantitatively entered into the first preparation kettle, the second preparation kettle and the third preparation kettle. The effect of water metering.

Description

technical field [0001] The invention relates to the technical field of styrene-butadiene latex, in particular to a water-based styrene-butadiene latex production device and a production method. Background technique [0002] SBR latex is a stable emulsion obtained by the polymerization of butadiene and styrene at low temperature. According to the difference of styrene content, emulsifier and polymerization temperature, there are many varieties, and their properties and uses are also different. SBR styrene-butadiene latex The latex asphalt modifier is specially developed according to the characteristics of modified asphalt and modified emulsified asphalt. In highway engineering, it is widely used in the preparation of various spray-type and mixing-type modified emulsified asphalt, as well as asphalt modification of high-grade pavement, bridge deck and other road works, such as micro-surface, slurry seal, and sticky oil. It is suitable for the modification of waterproof engine...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of water-based styrene-butadiene latex production device and production method, which solves the problem that the traditional water-based styrene-butadiene latex production device in the background technology is inconvenient when preparing initiator, defoamer, oxidizing agent and reducing agent. The rapid production of small sample fluids, the sample is tested first, and then a large amount of fluid with the same concentration is produced, resulting in errors in the concentration of fluid production, and the traditional water-based styrene-butadiene latex production equipment is not easy to set up linkage structures, resulting in the need for many The driving source of the group is a waste of resources. The traditional water-based styrene-butadiene latex production device is not convenient to measure the softened water, which leads to the problem that the concentration error is prone to occur when the fluid is produced.
