Aqueous nanometer composite polyester amino resin coating material and its preparation method

Abstract

The invention relates the aquosity nanometer polyester- amido resin coating material and preparing method. The invention cross-linking cures the aquosity nanometer polyester resin and amido resin to get the aquosity nanometer polyester- amido resin. The product has the advantages of good stabilization, diaphaneity, diaphaneity, brightness and abradability. The brightness of the coating is above 90%, the hardness is improved by 30-150%, and the abradability is improved by 20-70%. The coating can be used in woodware coating material, metal coating material and plastic coating material.

Description

technical field

[0001] The invention relates to the field of chemical industry, and relates to a water-based nano-composite polyester amino resin coating material and a preparation method thereof. Background technique

[0002] Whether it is metal coating materials, plastic coating materials, or wood coating materials, most of the coating materials currently used are solvent-based coating materials, which have high organic volatile compounds (VOC), and some coating materials contain more than 70% organic solvents. Seriously pollute the environment and endanger people's health. For this reason, developed countries have legislated to limit their VOC emissions, and my country has gradually promulgated the limit standards for harmful substances in decoration materials, which have restricted the VOC in traditional solvent-based coatings. The promulgation of these regulations is greatly conducive to the research and development of water-based coating materials, but so far, whether...
