Abstract

The invention belongs to the field of waterproof coating materials, and discloses a reactive single-component polyurethane root-puncture-resistant waterproof coating material and a preparation methodthereof, wherein the waterproof coating is added with a chemical root-retardant agent capable of carrying out a chemical reaction with isocyanate in a coating material, and the molecular structure ofthe chemical root-retardant agent contains a root-retardant active group and one or two hydroxyl groups capable of carrying out a chemical reaction with the main component isocyanate in a polyurethanecoating material. According to the invention, the root-puncture-resistant waterproof coating material has excellent physical properties; the root-retardant agent of the root-puncture-resistant waterproof coating material directly participates in a chemical reaction, so that the root-puncture-resistant waterproof coating material has reliable and durable root-puncture-resistant effect compared with traditional physical addition, and is a real reactive single-component polyurethane root-puncture-resistant waterproof coating material; and the root-puncture-resistant waterproof coating material is suitable for planting roofs in various environments.

Description

technical field [0001] The invention relates to the field of waterproof materials, more specifically, to a reactive single-component polyurethane root puncture-resistant waterproof coating and a preparation method thereof. Background technique [0002] The one-component polyurethane waterproof coating is composed of isocyanate and polyether as the main raw materials, and isocyanate group-containing prepolymer formed by addition polymerization reaction under the action of a catalyst, together with additives, fillers, solvents, etc., after mixing and other processes Processed. This type of coating is a reaction-curing coating, which solidifies after contacting with moisture in the air, and forms a dense and tough seamless overall protective film on the surface of the base layer. It has the characteristics of high strength, high elongation, and good water resistance. In the actual application process, it has strong adaptability to the deformation of the base layer, and is suit...
