preparation example Construction

[0022] Embodiments of the present invention further provide a method for preparing the above-mentioned colored reflective elastic coating for heat-insulating exterior walls, which includes the following steps:

[0023] Step S01, preparing the first mixture:

[0024] Add 15~25 parts of water to the container, and add 1.0~10.0 parts of hydroxyethyl cellulose aqueous solution, 0.2~2 parts of dispersant, 0.2~1.0 parts of multifunctional additives, 0.05~ 1.0 part preservative, 0.2~3.0 part anti-fouling agent, 1.0~5.0 part antifreeze and 0.1~0.5 part defoamer, the time interval between adding each two components is 2~10 minutes;

[0025] Step S02, preparing a second mixture:

[0026] Adjust the rotation speed to 1000~1500rpm, add 3~15 parts of color heat insulating pigments and 10~30 parts of pigments and fillers, and stir for 5~60 minutes;

[0027] Step S03, preparing a third mixture:

[0028] Adjust the speed to 800~1200rpm, add 30~50 parts of elastic emulsion, 1~15 parts of or...

Abstract

The invention is applicable to the field of coatings, and provides a color reflective heat-insulation exterior wall elastic coating and a preparation method thereof. The color reflective heat-insulation exterior wall elastic coating includes strong hydroxyethyl cellulose, ordinary emulsion, elastic emulsion and the like. The color reflective heat-insulation exterior wall elastic coating using the components in ratio has good heat-insulation performance, a variety of colors for selection, excellent elasticity, good contamination resistance and the like, total solar reflectance ratio and near infrared reflectance ratio are high, selected raw materials are preferably environmental-friendly, and the harm to the environment and human body is reduced.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a color reflective elastic coating for heat-insulating exterior walls and a preparation method thereof. Background technique [0002] Energy saving and emission reduction has become an urgent problem in all walks of life today. The construction industry accounts for about 30% of the total energy consumption, and there is a long way to go to promote building energy efficiency. Reflective thermal insulation coatings are more and more favored by architectural designers and users because of their advantages such as economical benefits, convenient use and good thermal insulation effects. In order to improve people's living environment and save energy, local governments have made unremitting efforts to vigorously promote thermal insulation coatings, such as DB34 / T 1505-2011 "Technical Regulations for the Application of Building Launched Thermal Insulation Coatings" launched by Anhui Province, ...
