Coating technology: production technology of polymer cement waterproof coating

The key point is that polymer waterproof coating is made from high performance polymer emulsion as the liquid material of the coating, and made of ordinary portland cement as filler and filler and auxiliaries The recommended formula is as follows: Raw material name action formula quality% Acrylate emulsion material 42.95 Ordinary portland cement powder 42.95 Light calcium carbonate Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coatings home: polymer waterproof coating is made of high-performance polymer emulsion as the liquid material of the coating, and made of ordinary portland cement as filler and filler and auxiliaries The recommended recipes are as follows: raw materials, formulation, quality, acrylate emulsion, 42.95 ordinary portland cement, 42.95 light calcium carbonate, body filling 8.79 TEXANOL ester alcohol, film forming agent 3 P-731 dispersant 0.3 dibutyl phthalate plasticizer 2 H2O diluent Cement is a kind of inorganic material with high hardness and excellent waterproof performance Compared with polymer, cement has excellent water resistance and weather resistance When the ratio of liquid to powder is constant, the elasticity and waterproof performance of polymer cement waterproof coating depend entirely on the elasticity and waterproof property of polymer emulsion The elasticity and water repellency of acrylate emulsion polymer emulsion mainly depend on the preparation process of acrylate, the selection and proportion of soft and hard monomer, the type and amount of functional monomer A polymer emulsion for polymer cement waterproof coating with high elasticity, high water resistance, high and low water resistance and high water resistance is introduced The raw material quality is BA 126 MMA 66 MAA 8 N- hydroxymethyl acrylamide / acrylamide 4.00/3.00 SDS 3 OP-10 5 NaHCO31.00 (NH4) 2S2O81.50 H2O 170 ammonia water proper amount of methyl phenol / melamine Production process 1, emulsion polymerization process semi continuous emulsion polymerization 1) 20% mixed monomers and 1/3 initiator, all emulsifier, part of water and pH buffer added to the reactor, heated to 80 + 1 C, 2) after polymerization to a certain extent, the remaining monomer and hair solution were added to the reactor continuously for polymerization within a certain time interval The conversion rate of reaction monomer was measured at regular intervals 3) when the conversion rate tends to be constant, the temperature rises to 90 degrees, and the heat preservation is 45min 4) the ammonia is adjusted to 8 to 9 by Ph, and then cooled to 40 degrees, 5 The acrylate mixture can be obtained by filtering the mixture with filter cloth 2, polymer cement preparation 1) pour the acrylate emulsion into the batching tank, start stirring, 2) slowly add the powder and other ingredients, stir well not less than 10min, without powder agglomeration 3) When the material is less, it can be mixed by hand When the material is larger, it is recommended to use a hand electric drill with a mixing blade for mixing During mixing, it is not allowed to add water or mix residual liquid and other impurities from the last mixing The prepared coating shall be used up within 2 hours Polymer waterproof coating is prepared from high performance polymer emulsion as the liquid material of the coating, with ordinary portland cement as powder and filler and additives The
