Melamine cyanamide formaldehyde resin is made by polycondensation of melamine and Du formaldehyde in acid or alkaline medium. There are three main forms of composite materials. (1) Glass fiber reinforced molding compound: short cut glass fiber is impregnated with melamine resin and various additives, and is made by loosening and drying. Molding plastics can be molded or injected into products. (2) Glass cloth laminate: it is made of glass cloth impregnated or coated with resin glue solution, dried and dried, then laminated at room temperature, and then heated and pressed on a press to solidify. (3) Compression molding powder: impregnating cellulose and asbestos fillers with resin and various additives. After drying, it is milled and sieved into pressure plastic powder. It can also be granulated into granular material. This composite material is used in advanced electrical insulation products, such as explosion-proof electrical accessories, electric tool insulation parts, arc resistant industrial accessories. Pressure molding powder is also often used to make daily necessities, tableware and so on.axing Melamine is a Melamine Dinnerware Manufacturer in China, and provides Valued products: Melamine Dinnerware, Melamine Tableware, Melamine dishes, Melamine plates, Melamine bowls, Melamine set, melamine cups, outdoor dinnerware melamine dinnerware manufacturers
Melamine Dinnerware Manufacturer Main uses:
Melamine resin can be prepared by condensation polymerization with formaldehyde, which can be used in plastics and coating industry, and also as anti folding and anti shrinking agent for textiles. The modified resin can be used as metallic coating with bright color, durability and good hardness.
It can also be used for strong and heat-resistant decorative sheet, moisture-proof paper and gray leather tanning agent, adhesive for synthetic fireproof laminate, fixing agent or hardening agent for waterproof agent, etc. 582 melamine resin was prepared from melamine, formaldehyde and butanol. It can be used as leveling agent for solvent based polyurethane coatings.
The characteristics of melamine resin adhesive are as follows
It has high chemical activity, high bonding strength, water resistance, high energy, high heat stability, strong low temperature curing ability, good wear resistance, fast curing and no need to add curing agent.
Compared with urea formaldehyde resin, melamine products have better hardness, wear resistance, chemical resistance and electrical insulation. However, the adhesive layer is easy to crack after curing, so it is not suitable to use modified melamine resin adhesive alone.
The modified melamine resin is widely used in furniture, vehicle construction and other aspects because of its short storage life, easy deterioration, powder can extend the storage life, and the price of modified melamine resin is high
