Description

Static mixing pipe capable of improving mixing effect of two-component adhesive

Technical Field

The invention relates to the technical field of static mixing pipes, in particular to a static mixing pipe capable of improving the mixing effect of a two-component adhesive.

Background

The two-component adhesive, also called AB adhesive, is composed of A, B two liquids, one of which is the original adhesive and the other is a hardener, and the two liquids can be mixed with each other to generate a curing effect, and is one of normal temperature hardening adhesives. The common two-component adhesive in the market is a two-component epoxy resin adhesive and has a quick-drying characteristic, after A, B two liquids are mixed, the adhesive is dried completely within 5 minutes at 25 ℃, and the drying time is shortened when the temperature is higher.

The two-component adhesive sold in the market is characterized in that two liquids are independently stored by adopting different packaging bottles, and can be used only after being respectively extruded out by a certain amount and uniformly stirred before being used. Because the stirring tools adopted by users are various, the stirring method and time are different, the stirring uniformity is different, and the bonding effect is inevitably influenced. In recent years, people designed and manufactured a packaging bottle, two kinds of A, B liquids were respectively contained in two bottle bodies parallel in the same packaging bottle, the bottlenecks of the two bottle bodies jointly formed a cylindrical glue outlet with external threads, then the threaded hole of the static mixing tube was adopted to be coupled with the external threads of the cylindrical glue outlet, and the A, B two kinds of liquids were simultaneously pushed into the static mixing tube to be statically mixed.

The static mixing pipe on the market is used for mixing A, B two liquids of the two-component adhesive. The static mixing tube does not need external force, and when A, B two liquids flow through the mixing tube, A, B two liquids are converted into a mixture through the laminating effect of a spiral mechanism in the mixing tube, so that A, B two liquids are mixed.

The static mixing pipe has a good mixing effect on the two-component adhesive. However, when the A, B two liquids flow through the mixing tube, the laminating effect of the spiral mechanism in the mixing tube is only used, so that the adhesive with low viscosity has a good mixing effect, and for the adhesive with high viscosity, the laminating effect of the spiral mechanism is limited, so that an ideal mixing effect is difficult to achieve. For adhesives with higher viscosity, it is necessary to design and manufacture a static mixing tube with better mixing effect.
