Waterborne epoxy modified perchlorethylene cast iron gear wear-resistant corrosion-resistant coating

Abstract

The invention relates to a modification method, process research, and product preparation of a novel material, and especially relates to a stabilizing and process optimizing method of a modified cast iron gear product. According to the invention, nano-grade SiO2 is adopted as a modification material; a nano-grade material with a mass percentage of 3-5% is added, wherein the material comprises 30% by mass of a nano-grade silica gel body; the mixture is stirred for 10-70min, wherein a stirring speed is 500-1200r / min, and a temperature during dispersing is no higher than 50 DEG C. The coating is advantaged in that perchlorethylene resin has the advantages of ultraviolet resistance, industrial atmosphere corrosion resistance, low cost, fast drying, and good water resistance. The coating has mould-resisting, flame-retarding, and decorative functions. Film-forming substances such as resin are optimized and modified, and a filling material which is also known as an enhancing material is optimized. The nano-grade SiO2 is adopted as a target modification material, such that cast iron wear resistance is improved.

Description

technical field [0001] The invention relates to a modification method, process research and product preparation of a new material; in particular, it refers to a method for product stabilization and process optimization of modified cast iron gears. Background technique [0002] Water-based paint uses water as a solvent or dispersion medium, so it is safe, non-toxic, low VOC content, and can be cleaned with water, which has many advantages. Water-based coatings can be generally divided into water-dilutable and emulsified. Latex type has been widely used in interior and exterior wall decoration of buildings, while water-diluted paint has begun to be widely used in industry. As we all know, China is the second largest paint market in the world, second only to the United States. The total output is expected to reach 6 million tons this year, so the development of green and environmentally friendly coatings has a broad development market, especially the development of water-base...

Problems solved by technology

Among the various types of coating products, among water-based resins, epoxy resin has good chemical stability, excellent adhesion, mechanical properties, electrical insulation and other properties; but there are also shortcomings. Outdoors, under ultraviolet radiation Easy to pulverize, poor decorative performance; when the curing is not complete, the water resistance of the coating film is not ideal
