What is the chemical structure of Methacryloxymethyltriethoxysilane?
The chemical structure of methacryloxymethyl triethoxysilane is quite interesting. This compound contains three parts, the first is methacryloxy. Methacryloyl, with alkenyl and carbonyl groups, the alkenyl group is in the shape of\ (CH_2 = C (CH_3) -\), and the carbonyl group is\ (C = O\). The two are connected, and the alkenyl group is rich in reactivity. It can be polymerized into polymers by addition reaction, which is commonly used in the preparation of polymeric materials.
is a methyl group, which is connected between the alkenyl group and the silicon atom as a bridge to connect, which affects the steric resistance and chemical activity of the compound.
The end is triethoxysilyl group, that is,\ (Si (OC_2H_5) _3\). The silicon atom is the center, connected to three ethoxy groups\ (- OC_2H_5\). The oxygen atom in the ethoxy group has a lone pair of electrons, which can be hydrolyzed to a silanol group\ (-SiOH\), and then condensed with other hydroxyl-containing substances to form a siloxy bond\ (-Si-O-Si-\). It has a wide range of uses in surface modification, cross-linking and curing of materials.
Overall, the chemical structure of methacryloxymethyl triethoxysilane combines alkenyl, carbonyl, methyl and triethoxysilane, which makes the compound have both organic and inorganic properties. It shows unique properties and application potential in many fields such as coatings, adhesives, composites, etc.
What are the main uses of Methacryloxymethyltriethoxysilane?
Methoxyacryloxymethyl triethoxysilane, which is a type of silicone coupling agent, has a wide range of uses.
First, in the field of composite materials, its function is remarkable. It can enhance the interfacial bonding force between inorganic materials and organic polymer materials. For example, in glass fiber reinforced plastics, the glass fiber can be closely connected to the resin matrix. Just like the tenon and mortise fit, the two work together to improve the mechanical properties of composites, such as strength and toughness, and can also enhance their water resistance and weather resistance.
Second, it is also commonly used in the field of coatings. Adding this substance can improve the adhesion of the coating to the substrate. It is like building a solid bridge between the paint and the substrate, making it not easy to fall off. At the same time, it can improve the hardness, wear resistance and chemical corrosion resistance of the coating, and prolong the service life of the coating.
Third, in terms of adhesives, it can improve the bonding strength of the adhesive to different materials. Whether it is the bonding of different materials such as metal and plastic, or ceramics and rubber, it can play a role in making the bonding more firm and reliable.
Fourth, in the field of fabric finishing, it can give the fabric special properties. If the fabric has the characteristics of waterproof, oil-proof, anti-fouling, etc., and does not affect the softness and air permeability of the fabric, it will make the fabric both practical and comfortable.
In addition, it will also be used in the preparation of some special functional materials. Through its unique chemical structure and reactivity, a special molecular structure is constructed, which endows the material with special functions such as light response and thermal response.
What are the physical properties of Methacryloxymethyltriethoxysilane?
"Tiangong" describes the physical properties of "methacryloxymethyl triethoxysilane" in ancient Chinese.
Methacryloxymethyl triethoxysilane, the outer layer is often a transparent liquid, and its taste is light, not pungent. Its boiling temperature has a fixed temperature, which is around 230 degrees, which is determined by its molecular force and other factors. The melting temperature is low, often in the low temperature environment, around minus 50 degrees, which makes it low in the phase, and it can also hold the flow.
Its density also has a law, 0.97 grams per cubic centimeter, and the distribution of the volume is uniform. The solubility is especially good, especially for many kinds of soluble materials such as toluene and ethanol, which can all be melted, just like water. This is due to the nature of the groups contained in the molecule. In water, it is slightly soluble, but under specific components, it can also be partially dispersed, like a flat wave, because of the delicate balance of its hydrophobic base.
In addition, its solubility is low to medium level, and it is not easy to create. It can be stored for a long time in dense devices. It is used in general applications to provide a fixed base. Such physical properties make methacryloxy methyltriethoxysilane useful in materials synthesis, materials manufacturing, and other fields.
Methacryloxymethyltriethoxysilane what are the precautions during use
For the use of methacryloxymethyl triethoxysilane, all the precautions should not be ignored.
First, this substance is reactive. When using it, avoid high temperature and open flames, and cover the risk of combustion and explosion due to its exposure. Store in a cool, dry and well-ventilated place, away from heat sources and fire, is the main rule.
Second, it may irritate the skin and eyes. When operating, be sure to wear protective equipment, such as protective gloves, goggles, etc. If you accidentally touch the skin, rinse with plenty of water quickly; if you enter the eyes, rinse with flowing water urgently, and seek medical treatment.
Third, the hydrolysis activity of this silane is quite high. When using it, beware of excessive contact with water vapor to prevent premature hydrolysis and polymerization, which will cause the performance to become easy. After opening the package, it should be used up as soon as possible. If it is not used up, it should be tightly sealed to reduce its contact with air.
Fourth, when using this substance in a specific system, it is necessary to study its solubility with other substances in the system in detail. Under different formulations and conditions, its reactivity and effect may vary, so it is advisable to conduct tests in advance to clarify its optimal dosage and process conditions before achieving the expected effect.
What is the market price range for Methacryloxymethyltriethoxysilane?
In the city of Guanfu, everything has a price, and the price varies depending on the supply and demand of the place. As for methacryloxymethyl triethoxysilane, its market price is quite difficult to put into words.
This compound is widely used in coatings, adhesives, and composites. The fluctuation of its price is actually influenced by many factors. The abundance of raw materials is related to cost. If the raw materials are widely produced and inexpensive, the price may drop; conversely, if the raw materials are rare, the price will rise.
The difficulty of the process is also a factor. If the preparation method is simple, the production capacity can increase, and the price may stabilize and decrease; however, if the process is complicated, it will take a lot of effort, and the price will be high.
The state of supply and demand in the market can especially determine the price. The user wants everything, the supply is difficult, and the price will jump; if the market is full of this product, and there are few people seeking it, the price will go down.
Looking at the market conditions in the past, the price of methacryloxymethyl triethoxysilane is between tens and hundreds of yuan per kilogram. However, this is only an approximate number. Today, its price may vary due to changes in the above-mentioned reasons. The market is volatile. If you want to know the exact price, you must carefully observe the market conditions and consult the industry.
