Abstract

The present invention is one kind of nano acrylic acid microemulsion, water-thinned heart reflecting and isolating paint with the nano acrylic acid microemulsion and their prodcution process. The present invention aims at solving the technological problems of available paint, which contains great amount of organic solvent to pollute environment and has poor heat reflecting and isoalting performance. The water-thinned heat reflecting and isolating paint consists of nano acrlic acid microemulsion, conventional acrylic acid emulsion, pigment, filler, infrared ray reflector, assistant, pH regulator, densifier and softened water. The paint contains no organic solvent and has excellent heat reflecting and isolating performance.

Description

Technical field: [0001] The invention relates to an acrylic nano-microemulsion, a water-based heat-reflecting heat-insulating coating produced by using the acrylic nano-micro-emulsion, and a manufacturing method of the acrylic nano-micro-emulsion and the water-based heat-reflecting heat-insulating coating. Background technique: [0002] Traditional coatings are mostly solvent-based, containing more than 30% organic solvents, and sometimes they are diluted with organic solvents during use. These solvents volatilize into the atmosphere during the construction process, which will not only cause harm to the health of the builders, but also pollute the environment and cause fire hazards. With the increasingly stringent environmental protection requirements around the world, it is the general trend to develop environmentally friendly coatings to replace solvent-based coatings. Ordinary coatings, especially dark-colored coatings, mostly absorb the infrared rays in sunlight and con...
