Problems solved by technology

There are two major problems in the existing silicone-acrylic resin preparation technology. One is that the related resin coating usually does not contain silicone oil or contains very little silicone oil. Most of them use silane coupling agent as silicone to modify the acrylate system. , resulting in limited silicone oil content in the system, resulting in comprehensive waterproofing of the coating and limited anti-corrosion performance; second, the cost of functional silicone monomers or polymers used is too high, which is not conducive to industrial production, resulting in greater application limitations

Abstract

The invention belongs to the technical field of coatings, and particularly relates to a silicone acrylic resin coating as well as a preparation method and application thereof. Acrylic acid which is low in price and wide in application is added into a system, so that adhesion of the coating can be obviously improved, and the process cost is greatly reduced; obtained silicone acrylic resin is synthesized in a free radical polymerization manner, and two incompatible substances are combined by virtue of the action of chemical bonds, so that the resin system can be durable, stable and effectively combined with the advantages of organic silicon and acrylic ester without adding an emulsifier.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a silicone acrylic resin coating and a preparation method and application thereof. Background technique [0002] In today's society, metal materials have been involved in all aspects of people's lives. As big as airplanes, ships, missiles, rockets, as small as mechanical parts, daily necessities, etc., all of them do not need metal materials. The metal will be affected by the environment to cause corrosion and rust, which will cause economic losses, energy waste, environmental pollution, and even catastrophic harm. It can be seen that the development of anti-corrosion technology is an important task. At present, applying a layer of anti-corrosion coating is the most direct and effective method. [0003] Because acrylic coatings have good weather resistance, acid and alkali resistance, high film-forming properties and strong adhesion, they are one of the important ...
