Abstract

The invention discloses hydrophobic type elastic paint. The components of the hydrophobic type elastic paint comprise a pure acrylic emulsion, a dispersing agent, a wetting agent, a coupling agent, film-forming auxiliaries, hydroxymethyl cellulose, calcined kaolin, gas phase silicon dioxide, deionized water, sodium p-styrene sulfonate and aluminium sesquioxide. The hydrophobic type elastic paint has good hydrophobicity, a paint film has the elongation percentage of 500% or above, tiny cracks can be covered, and the hydrophobic type elastic paint has high hardness and strength and good heat resistance, weather resistance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to the technical field of elastic coatings. Background technique [0002] Elastic paint is based on synthetic resin emulsion, formulated with pigments, fillers and additives. After a certain thickness is applied, it has an elastic functional paint that can overcome the fine cracks caused by the expansion and contraction of the base material. Typically include solvent-based, emulsion-based and inorganic-based elastic coatings. Among them, solvent-based and emulsion-type elastic coatings have high elongation and good film-forming effect, but relatively poor strength and hardness, poor weather resistance and heat resistance, while inorganic-type elastic coatings have relatively poor film-forming effect and generally low elasticity. Contents of the invention [0003] The purpose of the present invention is to provide an organic elastic coating with high strength and hardness, excell...
