AI Technical Summary

Technical Problem

Currently, exterior wall coatings have poor weather resistance and are prone to stain adhesion, leading to reduced heat insulation performance.

Method used

A chemical cross-linking network is formed by using modified polyacrylic acid, modified glass microspheres and modified additives. The amino groups on the modified additives react with the epoxy groups on the modified acrylic acid and modified glass microspheres to form a dense cross-linking structure, which improves the adhesion and hardness of the coating. The fluorinated polysiloxane structure on the modified additives is enriched on the coating surface, reducing the surface energy.

Benefits of technology

It improves the impact resistance of the coating, resists the erosion of moisture, ultraviolet rays and pollutants, slows down chalking, discoloration and peeling, significantly reduces the problem of easy dust accumulation in the coating, and maintains good heat insulation effect.

Abstract

This invention discloses a heat-insulating and energy-saving environmentally friendly exterior wall coating, comprising the following raw materials by weight: 100-120 parts modified acrylic acid, 10-20 parts modified additives, 20-30 parts modified glass microspheres, 15-25 parts rutile titanium dioxide, 0.2-0.8 parts leveling agent, 0.3-0.6 parts defoamer, 0.5-1 parts dispersant, and 40-50 parts water. During the mixing and coating process, the amino groups on the modified additives can react with the epoxy groups on the modified acrylic acid and the epoxy groups on the modified glass microspheres to form a chemical cross-linking network. The dense cross-linking structure can effectively resist the erosion of moisture, ultraviolet rays, and pollutants, and slow down chalking, discoloration, and peeling. The fluorinated polysiloxane structure on the modified additives, with fluorinated segments, will accumulate on the coating surface, significantly reducing surface energy and fundamentally solving the problem of easy dust accumulation in heat-insulating coatings.
