Abstract

The invention discloses a colored polymer cement waterproof coating which comprises a powder material and a liquid material, and the mass ratio of the liquid material to the powder material is (10-15):25; the powder material comprises the following components in parts by weight: 25-55 parts of white cement, 10-20 parts of heavy calcium carbonate and 35-60 parts of modified colored quartz sand, wherein the modified colored quartz sand is prepared by adopting modified pigment powder and EVA emulsion to pretreat quartz sand and then conducting roasting, and the mass ratio of the quartz sand to the modified pigment powder to the EVA emulsion is 1:(0.05-0.1):(0.2-0.4); and the liquid material comprises the following components in parts by weight: 80-100 parts of emulsion, 1-3 parts of a defoaming agent, and 10-15 parts of water, wherein the emulsion is formed by co-doping an EVA emulsion and a styrene-acrylic emulsion in a mass ratio of 1:(1-2.5). The invention also discloses a preparation method of the colored polymer cement waterproof coating. The prepared colored polymer cement waterproof coating is uniform in color, free of color attachment and floating phenomena, high in tensile strength, small in porosity, few in communicating holes and excellent in waterproof effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a colored polymer cement waterproof coating and a preparation method thereof. Background technique [0002] Polymer cement waterproof coating, also known as JS waterproof coating, is a two-component water-based waterproof coating that is formulated with polymer emulsion and cement as the main raw materials, adding fillers and other additives, and is cured by water volatilization and cement hydration reaction to form a film. coating. Polymer cement waterproof coating has the flexibility of emulsion and the high strength of cement. It is one of the most widely used water-based waterproof coatings in the waterproof market. It is widely used in the waterproofing of toilets, kitchens, balconies, basements and other areas. [0003] Traditional waterproof coatings usually add pigments, which are often mixed into waterproof coatings in the form of powder or color paste to inc...
