Problems solved by technology

[0009] The present invention solves the problem that when the roof and exterior wall of the existing building are exposed to strong solar heat radiation, the surface and indoor temperature will rise sharply, resulting in an increase in the ambient temperature, reducing the comfort of the living environment and increasing the power consumption of air conditioning and refrigeration. At th

Example Embodiment

[0017] Specific embodiment 1: This embodiment is a method for preparing a cool sunlight reflective waterproof coating for roof exterior walls, which is specifically carried out according to the following steps:

[0018] 1. Weigh 16%~19% deionized water, 0.5%~0.8% dispersant, 0.5%~1.0% defoamer A, 19%~24% filler, 22%~27% nano powder, 23%~28% emulsion, 8%~10% covering polymer, 0.2%~0.7% defoamer B, 0.3%~0.7% film-forming additives, 0.3%~0.6% anti-mold additives, 0.5%~0.8 %PH adjuster and remaining thickener premix;

[0019] 2. Add the deionized water and dispersant weighed in step 1 to the high-shear mixing and dispersing machine, control the linear speed to be 3.5m / s~5.0m / s, and stir, then add defoamer A and stir until Defoamer A is completely dissolved, add filler, adjust the linear speed of stirring to 20-25m / s, pH 7.8-8.2, stir for 15-25min, add nano powder, control the linear speed of stirring to 20-25m / s, and disperse Until the fineness of the slurry reaches 10-30μm, then adj...

Example Embodiment

[0021] Specific embodiment two: this embodiment is different from specific embodiment one in that the deionized water in step one meets the third-level water standard specified in GB / T6682-2008. Others are the same as the first embodiment.

Example Embodiment

[0022] Specific embodiment three: This embodiment is different from specific embodiment one or two in that: in step one, the dispersant is Rohm and Haas Orotan™ 1850E. Others are the same as the first or second embodiment.

Abstract

The invention provides a preparation method of a cool and sunlight-reflective waterproof coating for a roof and an outer wall and relates to a preparation method of waterproof coatings. The preparation method aims to solve the problems that the roof and the outer wall of an existing building are exposed to intense solar radiation, the surface and indoor temperature is raised sharply, accordingly the surrounding environmental temperature is raised, living environment comfort is lowered, power consumption for air conditioning refrigeration is increased, meanwhile, original waterproof materials on the roof and the outer wall are accelerated in corrosion and aging, original mechanical and chemical performance of the waterproof materials cannot be maintained, failure of efficacy is accelerated, and thus the roof and the outer wall leak. The preparation method includes the steps of 1, weighing raw materials; 2, preparing slurry; 3, preparing the waterproof coating. The prepared waterproof coating is free of formaldehyde and extra low in volatile organic compound, VOC is less than 50 g/L, the indoor coating use standard is reached, and the coating is an energy-saving and environmentally-friendly coating and used for industrial production.

Description

technical field [0001] The invention relates to a preparation method of waterproof paint. Background technique [0002] Building waterproof engineering is a sub-project to ensure that the structure of buildings (structures) is not invaded by water and the internal space is not harmed by water. Building waterproofing plays an important role in the whole construction project. It involves the basement, wall, floor, wall, roof and many other parts of the building (structure). Its function is to prevent the erosion of rainwater, production and domestic water leakage within the design durability period of the building (structure), to ensure that the building structure and internal space are not defaced, and to provide people with a comfortable and safe living space environment. [0003] House roof waterproofing in building waterproofing engineering is a systematic project, which is related to the normal operation of building functions and the service life of buildings. Over the...
