Example Embodiment
[0023] Example 1:
[0024] like Figure 4 As shown, the manufacturing process of the parylene film: heating the dimer (Di-para-xylylene) under the pressure of 1.0 torr to 150 degrees Celsius , decomposed into monomer (Monomer) parylene, and then sprayed into the reaction chamber (Chamber) at a pressure of 0.5 torr not higher than 680 degrees Celsius, at a pressure of 25 degrees Celsius and 0.1 torr To form a polymer (Polymer) parylene (para-xylylene), that is, to form a film.
Example Embodiment
[0025] Example 2:
[0026] like Figure 5 As shown, silicone resin refers to an organic group-containing polymer (Polymer) connected by Si-O-Si bonding of silicon and oxygen. Therefore, it has both organic and inorganic properties. That is, by analyzing the molecular structure of silicone resin, due to the combination of Si-O-Si, it has inorganic properties such as heat resistance, chemical stability, abrasion resistance, and high gloss; at the same time, because of the organic properties of its side chains, it has Excellent reactivity, solubility, productivity, etc. According to the different forms of silicone resin, it is divided into oil (oil), rubber (Rubber), resin (Resin) and other types. The higher the degree of cross-linking of silicon (Silicon Resin), the lower the activity and flexibility of the molecule, and the higher the hardness. The product with extremely high crosslink density is Silicone Resin.
Example Embodiment
[0027] Example 3:
[0028] like Image 6 As shown, the chemical basic unit of epoxy resin must contain epoxy (Epoxy) structure, which is usually produced by neutralizing epichlorohydrin and bisphenol A. Epoxy resins are difficult to use alone and require the addition of a hardener. Therefore, epoxy resins in the strict sense are intermediate products. Because bisphenol A epoxide is produced by the reaction of 2,2-bis-p-hydroxyphenylpropane BPA (Bisphenol A) and chloromethoxy cyclopropane ECH (ie Epichlorohybrine), it belongs to the benzene ring nucleus (BisphenolA), so it is difficult to rotate freely . Therefore, its chemical resistance, adhesion, toughness, high temperature resistance and other properties are outstanding. In addition, the ether group in the molecule can improve chemical resistance and plasticity. Hydrophilic hydroxyl groups and hydrophobic hydrocarbon groups are regularly arranged, so its adhesion is excellent.
