Abstract

The invention discloses a preparation method of nano TiO2 in-situ hybridization antibacterial waterproof coating treatment agent. The preparation method comprises the following steps: hydrolyzing titanate in a mixed solvent of alcohol and water to prepare nano TiO2 sol by adopting acid as a catalyst; slowly dropwise adding the prepared nano TiO2 sol into an alcohol solution of a silane coupling agent, after the nano TiO2 sol is completely added, reacting for 0.5 to 3 hours at the temperature of 60 to 80 DEG C, cooling, and obtaining the nano TiO2 hybridized antibacterial waterproof coating treatment agent. The preparation method is simple and easy, the prepared nano TiO2 hybridization antibacterial waterproof coating treatment agent is good in storage stability, transparent, free from layering, good in permeability and capable of being used as a coating treatment agent for materials such as fabrics, lumber, buildings and the like, has an anti-ultraviolet function, an anticorrosion function and excellent waterproof performance and does not influence the color and quality of the material.

Description

technical field [0001] The invention belongs to the field of surface treatment agents and relates to a nano-TiO 2 The invention discloses a preparation method of an in-situ hybrid antibacterial and waterproof coating treatment agent. Background technique [0002] Functional treatment of the surface of materials is a common demand in all fields, and the more common functional treatments include hydrophobic finishing and antibacterial finishing. Hydrophobic finishing is to endow the material with water-repellent properties. Hydrophobicity makes it difficult for water droplets to invade the interior of the material. At the same time, due to the low potential energy on the surface of the material, it is difficult for dirt to adhere, and the rolling of water droplets on the surface of the material can take away the stains on the material part, making the material still intact. Has a certain self-cleaning performance. The antibacterial property makes it impossible for bacteria t...
