What type of resin is melamine resin?
Melamine-formaldehyde resin is a polymer obtained by the reaction of melamine and formaldehyde. Also known as melamine formaldehyde resin and melamine resin. The English abbreviation MF. A cross-linking reaction occurs during processing and molding, and the product is an infusible thermosetting resin. It is customary to collectively refer to it and urea-formaldehyde resin as amino resin.

What does the XRD of melamine resin look like and who does it? Pass
How to prepare a sample with a smooth surface when performing XRD on polymer resin? Some books introduce the use of a cold press to cold press samples, but there is no cold press in the laboratory; some say that the polymer is first dissolved and then prepared into a film, but I want to analyze the crystallinity through XRD and see if the dissolution process will change. What about its crystallinity? I would be very grateful if you can give me some help.

The key depends on the crystallization condition of the sample under what molding conditions you want. Because of different processing history, thermal history, and solvent and other processing conditions, the crystallization condition of the sample, including crystal form and crystallinity, will change greatly. If you want to study the crystallization conditions under that molding condition, use that thermal history and processing conditions to prepare samples.
If you just have some raw materials in hand and want to measure the intrinsic information of the sample, you can ask the testing teacher if you can make powder samples, because most XRD can not only make flat surfaces, but also powder samples. Like this,

If you can grind the sample into powder, you can directly do powder XRD.

Melamine resin (MF), chemical name is melamine formaldehyde resin, English name is melamine, Chinese translation is Melnai. It has the advantages of non-toxic, tasteless, impact resistance, corrosion resistance, high temperature resistance, and low temperature resistance. The structure is compact, has strong hardness, is not easy to break, and has strong durability. The synthesis and uses of melamine-formaldehyde resin are similar to urea-formaldehyde resin. Under slightly alkaline conditions, melamine and formaldehyde add nucleophilically to form a hydroxyl derivative first. In principle, each amino group can form 2 hydroxymethyl groups, and 1 molecule may have 6 hydroxymethyl groups, but in fact there are Many monohydroxymethyl derivatives exist. Without acidification, melamine-formaldehyde resin can be cross-linked by heating alone, and the hydroxyl and amino groups condense to form methylene or methylene ether bridges. In order to improve the dissolution efficiency in solvents, methanol or butanol can also be used for etherification, and even hexaalkyl ethers can be produced. After acidification, the ether group is removed and a network structure is formed.
