Abstract
The invention provides a waterproof coating for an exterior wall of a building. The waterproof coating comprises, by weight, 30 to 45 parts of an organosilicon base material, 1 to 6 parts f an emulsifier, 3 to 5 parts of a catalyst, 1 to 3 parts of a pH value conditioning agent, 1 to 2 parts of butyl glycidyl ether, 5 to 8 parts of calcium carbonate, 2 to 5 parts of methacrylic acid and 12 to 22 parts of potassium persulphate, wherein the emulsifier is sodium alkyl sulfate or polyvinyl alcohol, the catalyst is (NH4)2S2O3, and the pH value conditioning agent is sodium hydroxide or potassium hydroxide. The waterproof coating provided by the invention has excellent waterproof impervious performance, can form a ventilating hydrophobic film with a certain depth on the exterior wall of the building to prevent invasive of moisture, exerts a mildew-resistant effect on an interior wall, is lightly influenced by ultraviolet ray, has the characteristics of a long service life and good endurance and is applicable to a plurality of building sites and convenient to construct.
Description
Technical field
The present invention relates to a kind of external wall waterproof paint, belong to building material technical field.
Background technology
Building water-proof paint is the thick liquid macroimolecule synthetic materials that is at normal temperatures without solid shape, after coating, solidifies the rear material that can form tough and tensile waterproof coating in substrate surface by the volatilization of solvent or evaporation or the reaction of moisture.The external wall waterproof paint is owing to be in outdoor application, and long-term acceptance is month after month exposed to the weather, and therefore compares with indoor waterproof paint, needs stronger water proof anti-seepage ability, and unfading is good, can resist ultraviolet irradiation.Present external wall water-proof material is short work-ing life, through the phenomenons such as decortication to occur of exposing to the weather in a few years, again brush and to pay a large amount of manpower and materials, therefore need to work out good endurance, the exterior wall waterproofing coating of long service life and the stronger water resistance of tool.
Summary of the invention
The purpose of this invention is to provide a kind of external wall waterproof paint, has good waterproof impervious characteristic, can form the ventilative hydrophobic film with certain depth at external wall, stop the invasion of moisture, simultaneously can also play the interior wall mildew-proof function, it is less affected by ultraviolet ray, has long service life, the characteristics of good endurance.
To achieve these goals, the technical solution used in the present invention is: a kind of external wall waterproof paint, include following component by weight: 30～45 parts of silicone binders, 1～6 part of emulsifying agent, 3～5 parts of catalyzer, 1 ~ 3 part of pH adjusting agent, 1～2 part of butylglycidyl ether, 5 ~ 8 parts in calcium carbonate, 2～5 parts of methacrylic acids, 12～22 parts of Potassium Persulphates.
Described emulsifying agent is sodium alkyl sulfate or polyvinyl alcohol.
Described catalyzer is (NH
4)
2S
2O
3
Described pH adjusting agent is sodium hydroxide or potassium hydroxide.
The preparation method is: emulsifying agent and butylglycidyl ether, calcium carbonate, methacrylic acid are added in the stainless steel stirring tank in proportion stir 2 ~ 4h, then add emulsifying agent, catalyzer and Potassium Persulphate, mix, adding at last silicone binder stirs, treat its normal-temperature reaction 5 ~ 8h, the material that forms is dropped in the high-pressure emulsification equipment high-pressure emulsification, leave standstill and remove impurity and suspended substance behind the 24h, regulate pH with pH adjusting agent at last and 4 ~ 5 get final product.
Directly with brush or atomizer continuous spray two to three times, keep dry in one day during use, can form at building exterior wall surface the ventilative hydrophobic film of certain depth.
A kind of external wall waterproof paint provided by the invention, has good waterproof impervious characteristic, can form the ventilative hydrophobic film with certain depth at external wall, stop the invasion of moisture, can also play the interior wall mildew-proof function simultaneously, it is less affected by ultraviolet ray, has long service life, the characteristics of good endurance go for multiple building lot, easy construction.
