Building waterproofing material

Abstract

The invention discloses a building waterproof material, which is made of the following raw materials in parts by weight: 35-40 parts of rubber asphalt, 10-15 parts of polyurethane, 3-8 parts of triethanolamine, and 3-6 parts of nano-magnesium oxide 0.1-0.3 parts of ultraviolet absorber, 5-12 parts of chlorinated polyethylene, 5-8 parts of toluene, 1-5 parts of epoxy resin, 0.6-1 part of rosin, 4-6 parts of calcium lignosulfonate, and 4-7 parts of sesame oil, 0.5-1 part of defoamer, 7-10 parts of asbestos powder, and 0-0.3 part of dispersant. The building waterproof material of the present invention integrates heat insulation performance and waterproof performance, has relatively strong compression resistance, long service life, excellent high temperature resistance, good extensibility, strong crack resistance, strong adhesion, and can form on the surface of objects. A waterproof layer can effectively avoid the oxidation of objects, and there is no overlapping seam to form an overall seal.

Description

technical field [0001] The invention relates to the technical field of material chemistry, in particular to a building waterproof material. Background technique [0002] At present, the waterproofing of various buildings is a key issue. Commonly used waterproof materials are various types of waterproof membranes, waterproof coatings, waterproof cement, etc. Waterproof membranes are generally hot construction, mostly baked by fire, the main disadvantage is that the bonding is not comprehensive, there are seams, and some special parts, such as corners, nozzles, etc. Not easy to repair. Waterproof coatings are usually applied cold. After the waterproof coating is mixed well, it can be painted at one time. There is no joint construction and strong adhesion. Its shortcomings are that its strength is not high, and its self-protection is not strong; and the function of this waterproof material is relatively single, which directly affects the quality of the building and the servi...
