What glue can be used to stick stainless steel to stainless steel?

1. The first thing is to determine the specific materials of the two things to be glued. Whether stainless steel and stainless steel are bonded or stainless steel is bonded to other materials.

2. If it is stainless steel and stainless steel to stick:

Acrylic acid structural adhesive, epoxy structural adhesive, organic silicon structural adhesive can be used for self-adhesive; acrylic acid has good strength and good airtightness, but it is a bit odor; epoxy structural adhesive should be used well, ordinary effect is not good, and weather resistance is also poor , It may leak water after a long time; the silicone structural adhesive has the best sealing performance, weather resistance and high temperature resistance.

3. Adhesion of stainless steel and other materials:

You can choose JL-498 special quick-drying glue for metal, it is simple to use, just drop a small drop of glue on the clean and dry bonding surface, that is, it is time to bond, and press the two bonding objects firmly, 8-15 seconds It can be fixed, the strength can be reached within 30 minutes, and the maximum strength can be reached within 24 hours. After bonding, it has high strength, good transparency, excellent water resistance, acid and alkali resistance, and is suitable for continuous production line operations.

For rigid PVC plastic bonding to metal, epoxy resin AB glue can also be used for bonding.
Notice:
If there is dust or oil on the bonding surface, please clean it and dry it before bonding;
If the metal surface is relatively smooth, in order to increase the bonding strength, the metal surface can be roughened.

The advantages of this: stainless steel and other objects can be tightly bonded together, and will not be released for a long time to crack. This method is relatively simple, operability is relatively strong, materials are relatively easy to obtain, and economical, so it is recommended Use the above method.

Glue classification

1. Rubber type

This type of sealant uses rubber as the base material. Commonly used rubbers include polysulfide rubber, silicone rubber, and polyurethane rubber.

Neoprene rubber and butyl rubber, etc.

2 Resin type sealants are based on resin. Commonly used resins include epoxy resin, unsaturated polyester resin,

Phenolic resin, polyacrylic resin, polyvinyl resin, etc.

3 oil-based

This type of sealant uses oil as the base material. Commonly used oils include various vegetable oils such as linseed oil and castor oil.

And tung oil, and animal oil (such as fish oil), etc.

Expansion information:

Glue is a substance that can bond two objects together. Glue does not exist independently, it must be applied between two objects in order to play a bonding role. The chemical composition of the glue, in an aqueous environment. The macromolecules in the glue (vinyl acetate in white glue is a kind of petroleum derivative) are all round particles, and the radius of the particles is generally between 0.5 and 5 μm. The bonding of objects is achieved by the tension between the macromolecules in the glue.

In the glue, water is the carrier of the medium polymer, and the water carries the polymer and slowly immerses into the tissue of the object. When the water in the glue disappears, the macromolecules in the glue will rely on mutual tension to bind the two objects together tightly. In the use of glue, if the amount of glue is too much, the polymers in the glue will crowd together; the polymers cannot produce good tension. The polymers crowd each other, and thus cannot form the strongest attraction between each other. At the same time, the moisture between the polymers is not easy to evaporate. This is why “the thicker the film, the worse the bonding effectiveness of the glue” during the bonding process. If the amount of glue is too much, the glue plays a “filling effect” rather than a bonding effect. The adhesion between objects does not rely on the adhesive force of the glue, but the “cohesion” of the glue. If it is not water-soluble, the principle is the same, that is, other solvents are used instead of water.
