Abstract

The invention discloses a polymer cement waterproof slurry and a preparation method thereof. The polymer cement waterproof slurry comprises a liquid material and a powder material; the liquid materialis prepared from the components:300-900 parts of a polymer emulsion, 0.5-4 parts of a defoamer, 0.5-4 parts of a bactericide and 100-600 parts of water; the powder material is prepared from the components:500-700 parts of cement, 200-400 parts of sand, 50-150 parts of a filler, 0.1-1 part of non-polar mineral oil, 0.1-5 parts of a water-retaining agent and 0.1-5 parts of water reducing agent; thepolymer emulsion is an acrylic emulsion and / or a styrene acrylate copolymer emulsion; and the weight ratio of the polymer emulsion and the water is (1.2-9) to 1. According to the polymer cement waterproof slurry, the amount of the water is lowered by improving the amount of emulsion in the liquid material, the dust removal effect of the product is relatively more excellent, and the bond strengthloss is reduced with the addition of the same mineral oil.

Description

technical field [0001] The invention belongs to the field of waterproof materials, and more specifically relates to a polymer cement waterproof slurry and a preparation method thereof. Background technique [0002] At this stage, with the gradual enhancement of waterproof awareness in the decoration market, waterproof materials have been widely used in the field of interior decoration. Polymer cement waterproof slurry has been used more and more in the interior decoration market because of its excellent mechanical properties, good waterproof and moisture-proof effect, strong adhesion and excellent adaptability to construction bases. During the use of the product, there are many links, including transportation, disassembly, mixing, etc., which will generate a lot of dust, which endangers the health and safety of workers and is not conducive to the management of green construction of interior decoration operations. Therefore, it is imminent to develop a dust-free polymer ceme...
