Abstract
The present invention relates to a preparation method of a microcapsule for a novel environment-friendly insulating building coating. The preparation method comprises the following steps of: under proper pressure, leading gas or greenhouse gas with good insulation to naturally overflow into water solution containing an emulsifying agent by an orifice, stirring to lead the water solution to form round bubbles, then adopting a layer-layer assembling technology, leading chitosan with positive electrons and yeast extract--sodium alginate with negative electrons to generate complex coacervation, precipitating in a layer-layer manner to form a bag, and forming the microcapsule by crosslinking. The present invention also discloses a novel microcapsule for the environment-friendly insulating building coating. The invention is novel and environment-friendly, preserves heat, saves energy, is economic and practical, has large market potential, convenient preservation, transportation and construction and leads the room to be more comfortable and elegant.
Description
technical field [0001] The invention belongs to a preparation method of novel microcapsules for environmental protection and thermal insulation architectural coatings. Background technique [0002] The architectural and decorative coatings at home and abroad are generally polyacrylic latex coatings. Polyacrylic acid is a petroleum resource and energy product, and the coating insulation effect of polyacrylic acid latex coating is not good. In the past 20 years, as a new type of coating that saves resources and energy, has no environmental pollution, simple process and high production efficiency, powder coating has been paid more and more attention by people. However, due to the high price and high construction requirements, it is used more in general engineering and less in household use. Contents of the invention [0003] One of the technical problems to be solved by the present invention is the formation of microbubbles through sharp holes and the stability of microbubb...
