Problems solved by technology

[0003] In the renovation of traditional old walls, in order to avoid the floating ash on the old walls from causing the paint to fall off, the old walls are reinforced with interface agents in advance. However, most of the interface agent materials currently on the market have some shortcomings, such as poor water resistance and poor adhesion. Low strength, especially difficult to penetrate into the interior of the base layer to thoroughly reinforce the loose base, poor adhesion and durability, and difficult to form a film at low temperature, it is necessary to add additional film-forming aids, resulting in slow drying speed and low construction efficiency

Abstract

The invention discloses a high-permeability interface reinforcement and a preparation method thereof, which relates to the field of organic-inorganic composite materials and aims to solve the problems of poor penetration and reinforcement of loose substrates by conventional acrylic interface agents. The present invention is an organic-inorganic composite polymer synthesized by using styrene, alkyl acrylate, and functional monomer as the core, and inorganic silicate modified by a silane coupling agent as the shell. The composite polymer can be used in old wall renovation scenes and has Strong penetration ability, high bonding strength, good adhesion, easy construction, and environmental protection.

Description

technical field [0001] The invention relates to a high-penetration interface strengthening agent and a preparation method thereof, belonging to the field of organic non-composite materials. Background technique [0002] Since the 1980s, my country's architectural coatings have developed rapidly, and various high and low-end products have come out, but on the whole, the level is not high, and many products are of poor quality. After years of rainwater washing, acid and alkali corrosion, resulting in Many exterior wall paints were damaged, and even some interior wall paints were touched off by hand, and the coatings were completely destroyed. Today, after years of real estate development in my country, the land use rate has gradually become saturated. Therefore, those old houses are mostly renovated. [0003] In the renovation of traditional old walls, in order to prevent the floating ash on the old walls from causing the paint to fall off, the old walls are reinforced with an...
