Abstract

The invention discloses polyethylene glycol modified melamine resin, and aims to provide modified melamine resin which has toughness and low water absorption and does not contain nonyl phenol. According to the technical scheme, the adhesive comprises the following components in parts by weight: 80 to 120 parts of polyethylene glycol, 50 to 70 parts of phenol, 180 to 240 parts of melamine, 2 to 3 parts of p-toluene sulfonic acid, 2.5 to 3.5 parts of triethanolamine, 4 to 5 parts of triethylamine, 330 to 430 parts of formaldehyde and 270 to 330 parts of solvent. Relates to the technical field of copper-clad plates.

Description

technical field [0001] The invention relates to a resin, in particular, a polyethylene glycol modified melamine resin, and a preparation method of the polyethylene glycol modified melamine resin; it belongs to the technical field of copper clad laminates. Background technique [0002] Polyethylene glycol (PEG) is a high molecular polymer with the chemical formula HO (CH 2 CH 2 O) n H, non-irritating, slightly bitter taste, good water solubility, and good compatibility with many organic components. It has excellent lubricity, moisture retention, dispersibility, and adhesive, and can be used as antistatic agent and softener, etc. It is widely used in processing and other industries. [0003] Because its molecular structure is a long flexible carbon chain and contains a large number of ether bonds to give it toughness, and the hydroxyl groups at both ends of the molecule can participate in the reaction with phenol and have good hydrophilicity, it is very suitable to replace...
