防水材料品种繁多，按其主要原料分为4类：
There are many kinds of waterproof materials, which can be divided into four categories according to their main raw materials
①沥青类防水材料。以天然沥青、石油沥青和煤沥青为主要原材料，制成的沥青油毡、纸胎沥青油毡、溶剂型和水乳型沥青类或沥青橡胶类涂料、油膏，具有良好的粘结性、塑性、抗水性、防腐性和耐久性。
① Asphalt waterproof materials. With natural asphalt, petroleum asphalt and coal tar pitch as main raw materials, asphalt felt, paper-based asphalt felt, solvent based and water emulsion asphalt or asphalt rubber coatings and ointments have good adhesion, plasticity, water resistance, corrosion resistance and durability.
②橡胶塑料类防水材料。以氯丁橡胶、丁基橡胶JDG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具 、三元乙丙橡胶、聚氯乙烯、聚异丁烯和聚氨酯等原材料，可制成弹性无胎防水卷材、防水薄膜、防水涂料、涂膜材料及油膏、胶泥、止水带等密封材料，具有抗拉强度高，弹性和延伸率大，粘结性、抗水性和耐气候性好等特点，可以冷用，使用年限较长。
② Rubber plastic waterproof materials. With chloroprene rubber, butyl rubber, ethylene propylene diene monomer rubber, polyvinyl chloride, polyisobutylene and polyurethane as raw materials, it can be made into elastic tire less waterproof membrane, waterproof film, waterproof coating, coating material and sealing materials such as ointment, mortar and waterstop. It has the characteristics of high tensile strength, high elasticity and elongation, good adhesion, water resistance and weather resistance, and can be used cold, It has a long service life.
