High-creep self-healing functional waterproof coating material

Abstract

The invention discloses a high-creep self-healing functional waterproof coating material, which comprises the following raw materials by weight: 50% of 90# asphalt, 8% of thermoplastic styrene butadiene rubber, 12% of powdered styrene butadiene rubber, 8% of a tackifying resin, 10% of a softening agent, 2% of a high temperature modifier, and 10% of talc powder. The preparation method comprises: heating 90# asphalt and thermoplastic styrene-butadiene rubber to a temperature of 190 DEG C, sequentially adding powdered styrene butadiene rubber, a tackifying resin, a softening agent and a high temperature modifier, maintaining the temperature at 190 DEG C, carrying out continuous stirring mixing for 2 h, adding talc powder, stirring for 1 h, and discharging the material. According to the present invention, the high-creep self-healing functional waterproof coating material is the multifunctional waterproof coating material, has excellent creep property, can effectively absorb the stress fromthe base layer, and can immediately form deformation under the action of the external stress to protect the waterproof layer from being damaged, such that the reliability of the waterproof layer canbe improved, and the service life of the waterproof layer can be prolonged.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a high-creep self-healing functional waterproof coating. Background technique [0002] The application of waterproof coatings has developed rapidly since the 1970s. Development and application of new building waterproof materials, new technologies, and new processes. It has made a new milestone in the overall level of my country's building waterproof engineering technology. [0003] At present, there are many kinds of waterproof coatings on the market, and the performance and construction methods of each variety are very different. The construction must be carried out by professionals and special tools to meet the quality requirements. Therefore, the construction must be completed while selling materials, and it is difficult to carry out general use. The promotion of universal use; waterproof coatings have strict requirements on the base surface, and the combination with the cement base...

Problems solved by technology

[0003] At present, there are many kinds of waterproof coatings on the market, and the performance and construction methods of each variety are very different. The construction must be carried out by professionals and special tools to meet the quality requirements. Therefore, the construction must be completed while selling materials, and it is difficult to carry out general use. The promotion of universal use; waterproof coatings have strict requirements on the base surface, and the combination with the cement base surface is poor, and it is easy to fall off in layers or as a whole; poor plasticity, it is difficult to deal with variable or small waterproof parts, and it is easy to leave Lower gaps and weak points; the thickness of the film layer is inconsistent, the mechanical properties of the film layer are affected by the temperature and humidity of the molding environment, the durability is short, and the performance gradually decays and decomposes after construction, and leakage occurs
