Environmentally-friendly epoxy modified acrylic coating for hardware parts, and preparation method thereof

Abstract

The invention provides an environmentally-friendly epoxy modified acrylic coating for hardware parts, and a preparation method thereof. The coating comprises, by weight, 60-80 parts of epoxy modifiedacrylic resin, 0.5-1 part of sodium methylene dinaphthalene sulfonate, 0.5-1 part of propylene glycol phenyl ether, 1-2 parts of hydroxypropyl methyl cellulose, 1-2 parts of dimethylethanolamine, 3-6parts of barium sulfate, 2-3 parts of calcium oxide, 1-2 parts of nanometer zinc oxide, 1-2 parts of graphene oxide and 10-15 parts of water. The epoxy modified acrylic resin is obtained through a ring-opening esterification reaction of an epoxy resin and an acrylic monomer, so the problems of sticking at a high temperature, high brittleness at a low temperature, poor water resistance, poor alkaliresistance and poor weather resistance of an acrylic coating are solved; and the graphene oxide and nanometer zinc oxide are added, so that the mechanical properties and the corrosion resistance of the coating are effectively improved.

Description

technical field [0001] The invention relates to the technical field of acrylic paints, in particular to an epoxy-modified acrylic hardware spare parts environment-friendly paint and a preparation method thereof. Background technique [0002] Hardware spare parts refer to machine parts or components made of hardware, as well as some small hardware products. It can be used alone or as an auxiliary tool. Such as hardware tools, hardware parts, daily hardware, construction hardware and security supplies, etc. Most hardware products are not final consumer goods. Instead, it is used as ancillary products, semi-finished products, and tools used in the production process for industrial manufacturing. Only a small part of daily hardware products (accessories) are tools and consumer goods necessary for people's lives. Hardware and hardware parts are mostly metal products, which are easily corroded in a humid atmosphere or in a special working environment, resulting in damage to th...

AI Technical Summary

Problems solved by technology

Hardware and hardware parts are mostly metal products, which are easily corroded in a humid atmosphere or in a special working environment, resulting in damage to the hardware parts and, in serious cases, damage to the entire machine. Therefore, anti-corrosion coating protection for hardware parts is quite necessary

However, acrylic paint is sticky at high temperature, brittle at low temperature, and has poor water resistance, alkali resistance and weather resistance, and its wide application has been restricted to a certain extent.
