Problems solved by technology

Some non-destructive testing techniques, such as ultrasonic reflection method, radiography, and infrared imaging, are often used to detect internal damage in concrete, but they all have certain limitations, and cannot be monitored in real time, and their repair is even more difficult
Most of the existing self-repairing materials are rigid coatings with no elongation and poor ability to resist cracking of building structures

Abstract

The invention discloses a two-component self-repairing polymer cement waterproof coating based on a liquid core optical fiber method. The coating comprises a liquid material and a powder material. Onthe basis, a corresponding preparation method of the product is established. The waterproof coating is a two-component coating composed of liquid and powder, is an intelligent high-elasticity waterproof coating, has higher elongation and structural cracking resistance, and has self-healing capability structurally. The coating can be self-repaired by support of a repair agent with a tubular fiber,damage caused by long-term mechanical action of the coating can be repaired, and accordingly, self-repair after cracks of the waterproof coating and restoration of the waterproof function are achieved. During use, the liquid material and the powder material are uniformly mixed for forming in the mass ratio of 1:1, the obtained coating has high elasticity, and cracks with water after water seepagecaused by cracking can be self-repaired. Accordingly, the problem that waterproof treatment is required to be performed again after a waterproof layer is damaged is solved, and the coating has higherpractical application value.

Description

technical field [0001] The invention belongs to the technical field of novel waterproof coatings, and in particular relates to a two-component self-repairing polymer cement waterproof coating based on a liquid-core optical fiber method and a preparation method thereof. Background technique [0002] In recent years, engineering accidents caused by the development of cracks in the waterproof layer are quite common. It can be said that the unlimited development of microscopic cracks in the waterproof layer is one of the root causes of building leakage accidents. Therefore, repairing cracks in the waterproof layer has always been a focus of attention and research in the academic and engineering circles. For surface macroscopic cracks, post-event passive repair methods are usually adopted, such as grouting, caulking and waterproofing replacement. Some non-destructive testing techniques, such as ultrasonic reflection method, radiography, and infrared imaging, are often used to de...
