Problems solved by technology

[0006] The method of adding UV light stabilizers to the coating to increase the service life has certain defects. Most of the UV light stabilizers used by Ciba Refining Company are non-polar oily organic compounds, which are not suitable for water-based architectural coatings, while those used by Clariant Company The UV stabilizer is a water emulsion, which can only be added in the let-down stage of the water-based architectural coating production process

Abstract

The preparation method of UV stabilizer for water exterior wall coating material is characterized by that it uses nano silicone dioxide as main raw material, adds the moistening dispersing agent, multifunctional dispersing agent, humectant, stabilizing agent, defoaming agent and fungicide and adopts the processes of stirring and ball-grinding so as to obtain the invented product which can greatly raise ageing resistanice of coating material. It is awater slurry body, and is friendly to environment when it is used, and has good compatibility with various water coatings, such as phenylpropyl water coating, pure propyl water coating, silicopropyl water coating ,ethylpropyl water coating and common latex paint and water-soluble resin, and can be added in the any process of coating production.

Description

technical field [0001] The invention relates to a preparation method of an ultraviolet light stabilizer for water-based building exterior wall coatings, in particular to a water-based building exterior which is prepared from silicon dioxide nano-scale ultrafine powder, various additives and water, etc. Preparation method of ultraviolet light stabilizer for wall paint. Background technique [0002] As we all know, due to long-term exposure to wind and rain, sun exposure, alternating dry and wet, and temperature changes, water-based exterior wall coatings will cause aging phenomena such as powdering, discoloration, cracking and peeling of the coating film, thus losing the coating. Decorative and protective functions on the exterior walls of buildings. After long-term experimental research and engineering applications, people have gradually realized that the aging of architectural exterior wall coatings is mainly caused by the direct exposure of a small amount of ultraviolet r...
