preparation example Construction

[0022] A preparation method for waterproof mortar, comprising the steps of:

[0023] (1) Take styrene and add it to the sodium hydroxide solution with a mass fraction of 5% according to the mass ratio of 1:1, stir and mix for 30~50min, let it stand for 2~3h, take the precipitate and wash it with distilled water, and distill under reduced pressure to obtain the reduced pressure Distillate, in parts by mass, takes 0.3~0.7 parts of n-bromobutane, 0.6~0.9 parts of aluminum trichloride, 80~90 parts of 1,2-dichloroethane, 30~40 parts of vacuum distillate, Stir and mix at 25-30°C for 3-4 hours to obtain a stirred mixture, take the stirred mixture and add methanol at a mass ratio of 1:6, stir and mix for 20-30 minutes, filter, and take the filter residue;

[0024] (2) Take polyvinyl alcohol and mix it with distilled water at a mass ratio of 1:40~50, heat up to 75~80°C and stir and mix for 20~30 minutes to obtain a mixture. In terms of parts by mass, take 70~90 parts of the mixture, 1~...

Abstract

The invention discloses a preparation method of a waterproof mortar and belongs to the field of building materials. The preparation method of the water proof mortar comprises mixing and cooling deionized water, span-80, peregal O, polyethylene glycol and octyl triethoxy silane to obtain a cooled mixture; mixing the cooled mixture with filter liquor to obtain a waterproof mortar mixed additive; stir-mixing tetraethoxysilane with absolute ethyl alcohol and then adding and mixing in hydrochloric acid to obtain a stirred mixture b, and mixing the stirred mixture b with the waterproof mortar mixedadditive to obtain a waterproof matrix; stir-mixing the waterproof matrix, nano clay, cement, silica sand, water reducer, redispersible powder and waste ceramic powder to obtain the waterproof mortar.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of waterproof mortar. Background technique [0002] The mortar used to make the mortar waterproof layer (also known as rigid waterproof) is called waterproof mortar. Waterproof mortar is also called cationic neoprene latex waterproof and anticorrosion material. Cationic chloroprene latex is a polymer molecule modified base polymer waterproof and anticorrosion system. It is a high polymer latex composed of imported epoxy resin modified latex, domestic neoprene latex, polyacrylate, synthetic rubber, various emulsifiers, modified latex, etc. It is a polymer waterproof and anti-corrosion material made by adding base materials, appropriate amount of chemical additives and fillers, and adding them through mastication, mixing, calendering and other processes. Select imported materials and domestic high-quality auxiliary materials, high-quality produc...
