EVA (Ethylene Vinyl Acetate) composite waterproof board and processing technology thereof
The invention discloses an EVA (Ethylene Vinyl Acetate) composite waterproof board and a processing technology thereof in the technical field of EVA composite waterproof board processing technologies, the EVA composite waterproof board is composed of an EVA waterproof base material, a non-woven geotextile, a high-molecular hot melt adhesive binder and an isolating membrane, and the non-woven geotextile and the isolating membrane can be directly purchased; the EVA waterproof base material and the high-molecular hot melt adhesive need to be automatically processed and prepared, then the raw materials are mixed and extruded through a screw extruder, and then a finished product EVA waterproof base material with a set thickness can be extruded through calendaring forming of a three-roller calendaring machine. Then the EVA waterproof base material, the non-woven geotextile, the macromolecule hot melt adhesive binder and the isolating membrane are sequentially subjected to hot press molding to obtain the EVA composite board, the range of materials is wide, the manufacturing cost is low, the tensile strength and the elongation at break are good, meanwhile, the flame retardance and the corrosion resistance of the waterproof board can be improved, and the service life is prolonged; and the construction quality of base surface waterproof treatment in water conservancy and civil engineering is effectively improved.
本发明公开了EVA复合防水板加工工艺技术领域的一种EVA复合防水板及其加工工艺，EVA复合防水板由EVA防水基材、无纺土工布、高分子热熔胶粘结剂以及隔离膜组成，其中无纺土工布和隔离膜可以直接购买所得，EVA防水基材和高分子热熔胶粘结剂需要进行自行加工制备，然后原料混合后经过螺杆挤出机挤出，再经过三辊压光机压光成型即可挤出设定厚度的成品EVA防水基材，再将EVA防水基材、无纺土工布、高分子热熔胶粘结剂和隔离膜依次热压成型得到EVA复合板，取材范围广，制造成本低，具有较好的抗拉强度及断裂伸长率，同时可以提高防水板的阻燃性和防腐性，提高使用寿命，有效提高了水利、土建工程中的基面防水处理的施工质量。
