Abstract

The invention discloses a waterproof material for construction. The waterproof material comprises the following raw materials in parts by weight: 2-6 parts of a waterproof agent, 30-40 parts of cement, 60-90 parts of mineral powder, 70-80 parts of quartz sand, 20-30 parts of an acrylic emulsion, 3-5 parts of aluminum hydroxide, 5-7 parts of triethanolamine, 2-4 parts of stearic acid, 5-7 parts of a thickener and 4-6 parts of a permeability crystalline agent. The waterproof material has a dense structure, has higher compressive strength and impermeability pressure resistance, is excellent in waterproofness, can be resistant to temperature shock, is adapted to climate temperature changes, and is not prone to cracks, less likely to cause leakage and less likely to age; meanwhile, raw material components of the waterproof material are safe and reliable and pollution-free to the environment, the raw materials are available, the cost is lower, and the process is simple, so that the waterproof material has higher practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a waterproof material for construction and a preparation method thereof. Background technique [0002] At present, mainstream waterproof materials mainly include waterproof coiled materials, polyurethane waterproof coatings, polymer cement-based waterproof materials, and cement-based osmotic crystalline waterproof materials. Among them, cement-based osmotic crystalline waterproof materials form water-insoluble crystals in concrete. , Block the capillary channels, so that the concrete is dense and waterproof. However, in practical applications, it has been found that such materials can be used as waterproof materials on indoor walls and floors, but they are often used as roof waterproof coatings in areas with frequent extreme weather such as heavy rain and hail, and leakage often occurs soon after use. [0003] Building waterproofing is the measures taken from the bu...
