Abstract

The present invention discloses a modified bitumen waterproof coiled material, a coating material and a preparation method thereof. The raw materials in the formula of the coating material comprise, by mass, 40-55% of bitumen, 10-15% of a machine oil, 10-18% of an SBS synthesis rubber, 2-8% of polypropylene, 5-20% of glue powder, 5-15% of a filler, and 4-10% of a regenerated resin, wherein the regenerated resin is the regenerated resin of a bisphenol A type epoxy resin, the epoxy equivalent weight of the bisphenol A type epoxy resin is 182-244 g / eq, and the particle size of the regenerated resin is 80-100 mesh. According to the present invention, the coating material production cost of the present invention is reduced by 3-8% compared with the coating material production cost in the prior art, problems of high temperature flowing, poor low temperature toughness, brittleness, cracking and the like are solved, and characteristics of excellent water resistance, no water absorption, no performance degeneration under long-term water erosion, excellent adhesion, and firm and durable binding with the base layer are provided.

Description

technical field [0001] The invention relates to a coating material for a modified asphalt waterproof coiled material, a modified asphalt waterproof coiled material containing the coated material, and a preparation method thereof. Background technique [0002] As people have higher requirements for buildings, the requirements for waterproofing are also rapidly increasing. Modified asphalt waterproofing membrane is an extremely important waterproof material. Improving quality and reducing cost are the problems faced by the modified bitumen waterproofing membrane industry. [0003] In the prior art, the modified asphalt waterproofing membrane is composed of a polyester tire or a glass fiber tire, and the upper and lower surfaces of the tire base are pasted with impregnated material layers, and the outer surface of the impregnated material layer is pasted with a modified asphalt coating material layer. The outer surface of the material layer is pasted with cladding isolation ma...
