Problems solved by technology

However, when the acrylic resin is used, in many cases, microcracks will be generated due to human or environmental reasons, which cannot be repaired in time, causing the cracks to grow and the coating to be damaged. Therefore, the application of this type of resin in the field of high-precision (precision instrument coating) is still There is a problem

Abstract

The invention provides self-monitoring acrylic ester and a preparation method and application thereof, and belongs to the technical field of acrylic ester paints.The invention prepares water-based acrylic resin and paints.The water-based acrylic resin and the paints.The self-monitoring acrylic ester is prepared by grafting molecule tetraphenyl ethylene containing aggregation-induced emission effect genes to acrylic ester; when the material generates cracks, the fluorescence intensity of the material is greatly improved due to the change of the molecular aggregation state at the cracks, and then the self-monitoring effect is achieved. The self-monitoring type water-based acrylic resin coating is low in preparation cost, does not change various properties of original coatings, can achieve the purpose of self-detection, can be widely applied to various high-end easily-worn devices or metal materials, facilitates identification of the wear degree of the devices or the metal materials, guarantees the safety of the devices and users, and is suitable for popularization and application. And the market prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of acrylic resin materials, and in particular relates to a self-monitoring acrylate and a preparation method thereof, a water-based acrylic resin coating with a self-detection function and a preparation method thereof. Background technique [0002] Acrylic resin is a general term for acrylic acid, methacrylic acid and its derivative polymers. Acrylic resin coatings are thermoplastic or thermosetting resin coatings or acrylic radiation coatings made of (meth)acrylates and styrene as the main body and acrylic resins obtained by copolymerization with other acrylates. [0003] Water-based acrylic resin is usually prepared by emulsion polymerization, which has the advantages of environmental protection, good chemical stability, and mature preparation technology. It is often used in water-based coatings, occupies an important proportion in the architectural coatings market, and is also widely used in the field of ...
