Abstract

The invention discloses a basalt fiber modified polymer cement waterproof coating, which is composed of a water agent and a powder agent, the water agent is composed of a high-molecular polymer emulsion, a compound auxiliary agent, a compound thickening agent and water; wherein the powder is prepared from white Portland cement, heavy calcium carbonate, graded quartz sand, functional filler and basalt chopped fibers; the weight ratio of the aqueous solution to the powder is 1:(1.8-2.2). The obtained coating material has characteristics of water resistance, heat insulation and heat insulation, can be suitable for most areas with large temperature difference, can reduce the cracking probability of the exposed polymer cement waterproof coating material, and can substantially improve acid and alkali resistance.

Description

technical field [0001] The application relates to the technical field of waterproof materials, in particular to a basalt fiber modified polymer cement waterproof coating. Background technique [0002] Polymer cement waterproof coating, commonly known as JS waterproof coating, is produced on the basis of polymer emulsion with additives and water. A two-component waterproof coating that can be applied by adding powder and stirring, and is widely used in civil and industrial building roofs, kitchens and bathrooms and other architectural parts. It is a waterproof material with both rigidity and flexibility, relying on the waterproof performance of its polymer emulsion after film formation and the strength of cement after hydration, and is widely recognized by waterproof manufacturers and customers. [0003] Patent CN 202010336289.X discloses a reflective heat-insulating waterproof coating and its preparation method and application. The waterproof coating includes: A material an...
