Preparation process of high-stress-resistance self-repairing water-based paint

Abstract

The invention discloses a preparation process of a high-stress-resistance self-repairing water-based paint, belongs to the field of paint preparation. According to the preparation process of the high-stress-resistance self-repairing water-based paint, resistance self-repairing particles are added in the preparation process, and during stirring, liquid guide fiber strips extend outwards, so that acoating layer formed by the water-based paint is higher in strength; when the coating layer is accidentally impacted, a plurality of resistance inner bags in the resistance self-repairing particles get close to each other towards the middle to abut against each other, the effect of absorbing impact force can be achieved, the deformation range of the resistance self-repairing particles can be effectively limited, and therefore the situation that the coating layer locally collapses due to too large deformation of the resistance self-repairing particles is effectively avoided. The strength and stability of the formed coating layer are guaranteed, the formed coating layer is not prone to peeling, bulging and falling off due to excessive local stress, meanwhile, when the coating layer is impacted, the resistance self-repairing particles near the impact point are extruded, the latex solution inside the self-repairing particles overflows to the impact position along the liquid guide fiber strips, and therefore the strength damaged by impact is effectively compensated for.

Description

technical field [0001] The invention relates to the field of paint preparation, and more specifically, relates to a preparation process of a highly stress-resistant self-repairing water-based paint. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. According to the type of binder in the coating, water-based coatings are divided into two categories: natural water-based coatings of natural substances or minerals (such as potassium silicate) and petrochemical water-based coatings of artificial synthetic resins (such as acrylic resins). Only water-based coatings of artificial synthetic resins are described here. [0003] Water-based paints include water-soluble paints, water-diluted paints, and water-dispersible paints (latex paints). Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products, in addition to water-so...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the object of the present invention is to provide a kind of preparation process of high stress resistance self-repairing type water-based paint, which through the resistance self-repairing particles added in the preparation process, when stirring, the liquid-conducting fiber strip Extend outward, so that the strength of the coating formed by this water-based paint is higher, so that it is not easy to produce large cracks when it is accidentally hit. Close to the pressure, it can not only absorb the impact force, but also effectively limit the deformation range of the resistance self-healing particles, so as to effectively avoid the local collapse of the coating due to excessive deformation, thereby ensuring the strength of the formed coating And stability, so that the formed coating is not easy to bulge and fall due to excessive local force. At the same time, when it is impacted, the resistance self-repairing particles near the impact point are squeezed and the latex liquid inside is along the fluid-conducting fiber strip. Spills to the point of impact, thus effectively making up for lost strength due to impact
