Embodiment 1

[0035] Production methods of multifunctional coatings:

[0036] Weigh the following components in terms of weight fractions: 130 parts of sodium borosilicate hollow microspheres, 130 parts of aluminum silicate, 115 parts of silica lime, 2 parts of thickener, 3 parts of defoamer, 2 parts of dispersant, ethylene glycol 28 parts of alcohol, 5 parts of polyoxypropylene wetting agent, 450 parts of pure acrylic emulsion, and 120 parts of water. The paint also contains 5 parts of sodium hydroxide pH regulator and 2 parts of preservative. Add water, thickener, defoamer, dispersant, ethylene glycol, sodium hydroxide pH regulator and preservative into the mixer, and stir until uniform at 1250rpm; add pure acrylic emulsion, and stir at 1750rpm until uniform; Add sodium borosilicate hollow microspheres, aluminum silicate and silica lime, stir at 760 rpm until uniform; sieve through a 155-mesh sieve.

[0037] After testing, its tensile strength is greater than 1MPa, its solar reflectance...

Abstract

The invention relates to a multifunctional coating and a productive technology thereof. The multifunctional coating comprises the following raw material in parts by weight: 50-190 parts of hollow borsal microspheres, 44-125 parts of aluminium silicate, 44-135 parts of siliceous lime, 2-5 parts of thickening agent, 1-10 parts of deforming agent, 1-7 parts of dispersing agent, 8-35 parts of ethylene glycol, 3-10 parts of wetting agent, 180-450 parts of latex paint emulsion and 100-350 parts of water. The multifunctional coating is formed by the hollow borsal microspheres suspended in inertia latex; the microstructures of the microspheres are beneficial to the reflection and scattering of infrared rays; in addition, the microspheres of the invention are hollow closed spheres and have very low coefficient of heat conductivity; the microspheres added to the coating can form a number of independent microscopic heat insulation cavities, thereby greatly increasing the thermal insulation of a paint film; and meanwhile, the multifunctional coating of the invention can supply enough negative ions to ensure indoor air to be good and simultaneously has very good anti-bacterium effect.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a multifunctional coating used for building surfaces and a production process thereof. Background technique [0002] At present, the existing building wall insulation coatings in my country are usually based on increasing the gas phase void ratio, reducing the thermal conductivity and conducting heat transfer, such as fiber insulation materials and profile insulation materials. Fiber-based thermal insulation materials achieve thermal insulation by improving convective heat transfer and radiation heat transfer, and require thicker coatings; profile-based inorganic thermal insulation materials need to be assembled and constructed, and there are many seams, which affect the appearance, poor waterproofness, and short service life. and other shortcomings. [0003] In addition, with the improvement of people's living standards and the extensive use of household appliances and air conditioners,...
