Abstract

The invention relates to a moisture barrier material of asphalt. The moisture barrier material of asphalt is prepared from the following components in parts by weight: 100 parts of petroleum asphalt, 30-45 parts of zinc yellow, 10-15 parts of heavy diesel fuel, 5-8 parts of xylene, 10-14 parts of asbestos wools, 6-8 parts of mica iron oxide, 10-20 parts of tung oil, 30-35 parts of vinyl acetate, 5-8 parts of aluminum stearate, 10-15 parts of butyl acrylate, 2-5 parts of butanol, 4-10 parts of methyl methacrylate and 2-3 parts of a curing agent. The material is good in bonding strength and free from toxicity, and the time for surface dry is 2-3 hours and the time for hard dry is 8-10 hours. The tensile strength of the product is 200-300MPa, and the product is good in water resistance and stability, waterproof and moistureproof. The material is impermeable at 0.3MPa and no leakage is available within 1 hour. The elongation at break of the product is 500%, and the material is flawless at -30 DEG C and can be widely produced and continuously replace existing materials.

Description

technical field [0001] The application belongs to the field of asphalt materials, in particular to an asphalt moisture-proof material. Background technique [0002] Asphalt is a dark brown complex mixture composed of different molecular weight hydrocarbons and their non-metallic derivatives. It is in liquid state and is a waterproof, moisture-proof and anti-corrosion organic gelling material. It is used in paint, plastic, rubber and other industries as well as road paving. In civil engineering, asphalt is a widely used waterproof material and anti-corrosion material. It is mainly used in the waterproofing of roofs, grounds, and underground structures, and the anti-corrosion of wood and steel. Asphalt is also a widely used pavement structure cementing material in road engineering. It can be used to build asphalt pavement with different structures after it is matched with different mineral materials in proportion. [0003] The domestic heavy-traffic asphalt market is mostly o...
