Abstract

The invention discloses a one-component polyurethane waterproof coating prepared by a step-by-step method, which mainly consists of the following components: 15-25% polyoxypropylene glycol, 5-15% polyoxypropylene trihydric alcohol, ‑2.6% toluene diisocyanate, 1.8%‑4.0% diphenylmethane diisocyanate, 5‑10% plasticizer, 30‑45% filler, 1‑2% pigment, 0.2‑0.4% catalyst , 0.5‑1.0% antioxidant, 0.5‑1.0% UV absorber, 0.2%‑0.4% defoamer, 0.2%‑0.4% dispersant, 5‑10% composite anti-sagging agent, The polyurethane waterproof coating is polymerized by stepwise polymerization during the preparation process, and the free TDI in the formula is removed. It is environmentally friendly and non-toxic, has excellent anti-sag effect, good heat resistance and aging resistance, and is suitable for indoor waterproofing. High-efficiency waterproof coating for construction.

Description

technical field [0001] The invention relates to an environment-friendly one-component polyurethane waterproof coating and relates to the field of architectural waterproof coatings. Background technique [0002] As a widely used waterproof material, one-component polyurethane waterproof coating has the characteristics of good elasticity, high strength, good adhesion and excellent tear resistance. It is widely used in the field of building waterproofing. It is currently the only waterproof membrane in China The most widely used waterproof material outside the series of products. The isocyanate types used in one-component polyurethane waterproof coatings are mainly toluene diisocyanate and diphenylmethane diisocyanate. The particularity of structure and performance caused by other various isocyanates is generally not suitable for polyurethane waterproof materials that meet the national standard GB / T 19205-2013 However, there are also different shortcomings when using the above...
