Composition of epoxy resin adhesive (Part 2)

10, glycidyl amine epoxy resin

11, alicyclic epoxy resin

chemistry according to the report of market research agency research and markets, it is called alicyclic dioxide, which is usually a kind of epoxy compound obtained by oxidizing the corresponding unsaturated lipids and family compounds with peroxide organic acid. The water content in the structure has an alicyclic ring, and the epoxy group is connected to the alicyclic ring. Since epichlorohydrin is not used as raw material in the synthesis, the organic chlorine content of the product is 0, which has excellent electrical properties, high volume resistivity and surface resistivity, and good arc resistance and leakage trace resistance. The cured product has high crosslinking density, high heat resistance, good weather resistance, UV and electronic radiation resistance

12. TDE-85 Epoxy Resin (chemical name: 4,5-epoxy cyclohexane-1,2-dicarboxylic acid diglycidyl ester)

13. Polybutadiene epoxy resin

polybutadiene epoxy resin, also known as epoxidized polybutadiene resin, uses 1,3-butadiene as raw material and metal sodium as catalyst in solvent

14. Fluorinated epoxy resin

due to the introduction of fluorine atoms, the molecular structure is dense, and the carbon and fluorine atoms are closely arranged around the main chain of the resin. Therefore, the central surface tension, friction coefficient and refractive index are very low, so that the required products can be produced. The production system developed by Jinfa Technology Co., Ltd., a supplier of corrosion-resistant modified plastics, has realized the intelligent manufacturing, wear resistance, heat resistance, pollution resistance and durability of special engineering plastics. But it is too expensive to be used for general purposes

15. Polyether epoxy resin

is prepared by polycondensation of polypropylene glycol and epichlorohydrin in the presence of sodium hydroxide. Light yellow uniform liquid

16. Polyurethane epoxy resin

is also known as epoxy carbamate resin. Polyester (or ether) polyols and epichlorohydrin generate polyol glycidyl ether under the action of BF3 and NaOH, and then add and polycondensate with diisocyanate to prepare

17 Naphthalene epoxy resin

is synthesized from naphthol and formaldehyde into linear naphthol phenolic resin or Dihydroxynaphthalene (ndol) and epichlorohydrin by condensation polymerization under the catalysis of sodium hydroxide. It has high heat resistance, low water absorption and small linear expansion coefficient

18. Silicone epoxy resin

is an epoxide containing silicon in the molecular structure, which is formed by the co condensation of polymethylphenylsiloxane and epoxy resin. Toluene as solution, light yellow uniform liquid

19, organic titanium epoxy resin

is obtained by the reaction of hydroxyl in bisphenol A epoxy resin with n-butyl titanate. The introduction of metal element titanium into the resin not only solves the problems of increased water absorption, moisture resistance and reduced electrical properties caused by the presence of hydroxyl groups, but also leads to the P-D conjugation effect in the macromolecular chain due to the direct connection between the oxygen atom with P electron in the resin and the titanium with d electron vacancy, which significantly improves the heat aging resistance and better dielectric properties. The appearance is yellow to amber high viscosity transparent liquid

20. The chemical name of the organic boron epoxy resin is polyepoxy butyl carborane

21. The oxygen-containing epoxy resin refers to the resin with phosphorus and non oxygen groups in the same water content. The phosphorus containing epoxy resin is prepared by the reaction of trimethylol phosphide oxygen and epichlorohydrin
