Description

Technical field [0001] This application belongs to the field of asphalt waterproof materials, especially involving an asphalt polylefin waterproof material. Background technique [0002] Asphalt is a product of the process of crude oil processing. At room temperature, it is black or dark brown viscous liquid or solid. It is a brown -black organic glue condensed substance, including natural asphalt, oil asphalt, shale asphalt and coalThere are four types such as tar.The main ingredients are asphalt and resin, followed by high -boiling spots of mineral oil and a small amount of oxygen, sulfur and chlorine compounds.There is liquid, semi -solid, or solid state, crispy at low temperature, good adhesion and anticorrosive performance.Asphalt is a dark brown complex mixture composed of different molecular weight hydrocarbons and its non -metallic derivatives. It is liquid and is a waterproof moisture -proof and anticorrosive organic gel material.Used for coatings, plastic, rubber and ot...
