Inorganic high-temperature glue:

Compared to organic glue, this glue will be able to withstand a higher temperature and can withstand a high temperature of 1800.

Targeted comparison according to different needs and conditions to select the most suitable glue.

Glue objects. It is necessary to select the type of adhesive, its properties, adhesive area and stiffness, and generally speaking, the properties of the desired adhesive should be similar to the performance of the adhesive.

Bonding environment. Since factors such as climate, light, heat, moisture, and mold can affect the strength of the bond, choose the right adhesive according to the conditions of the bonding structure.

Economical. By using low-cost products that meet performance requirements, a balance between performance and contact can be struck.

Depending on the location of use, do not use multi-purpose general-purpose adhesives.

For ventilation ducts or substrates that are not suitable for conventional cement-based bonding, such as gold, wood, or high-temperature environments, paste-like structural adhesives or flexible cement mortars should be used.

For liquid adhesives and paste adhesives, in addition to the physical property indicators, environmental properties should also be considered, as well as whether they contain formaldehyde, toluene, xylene and other harmful substances. In the case of powder adhesives, environmental performance is not considered by default. There are no harmful substances in the dry powder, such as:

Formaldehyde, toluene and xylene.

1. Butyl rubber.

Generally, the use temperature of butyl rubber does not exceed 150 degrees. Only butyl rubber with resin vulcanization can work at 150-180 degrees for a long time. Combining 10-20 parts of neoprene or chlorosulfonated polyethylene with general butyl rubber can improve heat resistance.

2. Halobutyl rubber.

The heat resistance of chlorobutyl rubber is related to the vulcanization system, generally chlorinated butyl rubber, the maximum temperature is 130-150 for long-term use, and 160-170 degrees when there is no air.

3. Chlorosulfonated polyethylene rubber.

The maximum service temperature of chlorosulfonated polyethylene for a long time (1000h) is 130 degrees. A short period of time can allow an elevation of up to 160 degrees.

4. Chlorohydrin rubber.

The heat resistance is better than that of nitrile rubber. Homopolymer CHR has better heat resistance than copolymer CHR.

5. Acrylates.

The heat resistance is higher than that of nitrile rubber and lower than that of fluoroelastomer. The long-term (1000h) use temperature is 170 degrees, and the short-term (70h) use temperature can be increased to 200 degrees.

Extended Materials. Rubber processing:

This process includes basic processes such as plasticizing, mixing, calendering or extrusion, molding and vulcanization, each process has different requirements for the product, and is matched with a number of auxiliary operations. In order to be able to add various required compounding agents to rubber, raw rubber first needs to be plasticized to improve its plasticity; Then through mixing, carbon black and various rubber additives are evenly mixed with rubber into rubber compounds.

The rubber material is extruded to make a certain shape blank; then make it combined with the textile material (or with metal material) that has been calendered or glued together to form a semi-finished product; Finally, after vulcanization, the semi-finished products with plastic properties are made into highly elastic end products.

Generally, rubber made of ordinary materials is not resistant to high temperature and is easy to oxidize, but rubber with special materials is very resistant to high temperatures. The high-temperature rubber mat is a kind of vinylidene fluoride and fluorine-free, propylene fluoride and propylene copolymer colloidal elastomer.

Natural rubber is not very resistant to high temperatures, usually around 120 degrees Celsius. Some other rubbers are also generally not very resistant to high temperatures, up to about 140 degrees Celsius.

Silicone can withstand high temperatures, ordinary can reach: about 150-200 degrees Celsius, high-grade silicone rubber can reach 150 degrees Celsius.

Of course, if there are many other substances added to the rubber, the situation changes, it may reach 500 degrees Celsius, but this is only a mixture of rubber, not rubber, and some silicone rubber mixtures can reach 800 degrees Celsius, which is also a mixture of silicone rubber, not silicone rubber.

Hope it helps.

In the decoration process, it is often necessary to use some high-temperature resistant glue, especially in industrial scenes. There are many types of high-temperature resistant adhesives on the market, but the requirements of glue are also different for different construction environments and different substrate surfaces. So, what are the high-temperature resistant glues?

How to choose the right epoxy adhesive? Let's take you to find out.

High-temperature resistant adhesives include temperature-resistant epoxy adhesives, inorganic high-temperature adhesives, organosilicon adhesives, phenolic resin adhesives, etc., among which temperature-resistant epoxy adhesives are the most common organic high-temperature adhesives in construction. This glue can withstand temperatures below 400, in addition to the characteristics of high temperature resistance, it also has insulation, thermal conductivity, flame retardant and other functions.

How to choose the right epoxy adhesive.

1. Confirm the use of epoxy adhesive.

Before choosing an epoxy adhesive, it is necessary to confirm its use and then choose the right adhesive according to its use. If it is used for bonding, then it is necessary to consider the strength, but if it is used for coating, it is necessary to consider its brushability and fluidity.

2. Confirm the cost of epoxy adhesive.

When choosing an epoxy adhesive, there is also a need to consider the cost aspect. If it is used for large quantities of potting, the cost must be controlled. However, if you want to bond a precision product, you need to consider electrical performance and convenience.

3. Confirm the viscosity of epoxy adhesive.

When choosing an epoxy adhesive, it is also important to pay attention to its viscosity, as it is related to the size of the gap in the filler and the dispensing efficiency. Generally speaking, the higher the viscosity of the glue, the larger the filling gap and the poor flowability.

4. Confirm the color of epoxy adhesive.

Epoxy adhesives come in a variety of colors, such as red, blue, black, and transparent. Therefore, when choosing, you must choose according to the actual situation.
