Resin for metal coiled material and preparation method thereof

Abstract

The invention discloses resin for a metal coiled material. The resin comprises the following raw materials in parts by weight: 35-45 parts of unsaturated polyester resin, 10-15 parts of initiator, 10-13 parts of crosslinking agent, 10-14 parts of catalyst, 15-20 parts of pigment filler, 5-10 parts of isophthalic acid, 10-14 parts of surface hydrophobic agent, 10-13 parts of ethylene glycol, 10-15parts of waste PCB powder, 10-15 parts of carbolic acid, 5-10 parts of methylene oxide, 3-5 parts of an acidity and alkalinity regulator, 8-10 parts of a penetrating agent, and 10-12 parts of a diluent, the preparation method comprises the following steps: weighing and proportioning raw materials, preparing polyester resin raw materials, preparing a reaction solution, preparing a resin finished product, inspecting, packaging and warehousing. The dicumyl peroxide, the isophthalic acid, the ethylene glycol, the waste PCB powder and the surface hydrophobic agent are added into the preparation rawmaterials so that the prepared resin has high comprehensive performance, and the preparation method is simple, easy to operate and low in production cost.

Description

technical field [0001] The invention relates to the technical field of resin coatings, in particular to a resin for metal coils and a preparation method thereof. Background technique [0002] Metal materials refer to materials with luster, ductility, easy conduction, heat transfer and other properties. They are generally divided into ferrous metals and non-ferrous metals. Ferrous metals include iron, chromium, manganese, etc. Among them, steel is the basic structural material, called It is the "skeleton of industry", and the metal coil is a roll-shaped metal material. During the production and processing of the metal coil, it is necessary to coat the surface of the metal coil with resin coating to improve the comprehensive performance of the metal coil and protect the metal coil. The material plays a certain protective role, making the metal coil more practical in subsequent use; [0003] Most of the existing resin coatings for metal coils have a single component, the prepa...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing resin coatings for metal coils have a single component, the preparation process is complicated, it is not easy to operate, and the requirements for production workers are relatively high. The prepared resin has poor comprehensive performance, insufficient strength and aging resistance, and does not have good sun protection. Performance, hardness and impact resistance are also low, and there is no good flame retardancy. In addition, the water resistance and anti-fouling performance are also poor, which brings inconvenience to the later use of metal coils. Therefore, the present invention proposes a metal coil Use resin and preparation method thereof to solve the problems existing in the prior art
