Method for preparing microcapsule emulsion used for novel heat-preserving and sound-insulating building coating

Abstract

The invention provides a method for preparing a microcapsule emulsion used for a novel heat-preserving and sound-insulating building coating. The method comprises the following steps: under proper pressure, overflowing the gas or greenhouse gas with good heat insulation performance into water solution containing emulsifying agent naturally through an orifice, and mixing the solution so as to form round bubbles uniformly; and subsequently adopting an emulsion polycondensation technology to lead a wall material to form a capsule by polycondensation, thus preparing the microcapsule emulsion used for the coating. The invention also discloses a microcapsule emulsion used for the novel heat-preserving and heat-insulating building coating. The invention has heat preservation, sound insulation and energy-saving performances, meets the environmental protection requirement, has good smoothness and large viscosity, is economical, has large market potential and convenient construction and is more comfortable for living.

Description

technical field [0001] The invention belongs to the preparation of a novel microcapsule emulsion for thermal insulation and sound insulation architectural paint. Background technique [0002] At present, domestic and foreign architectural and decorative coatings generally do not have thermal insulation and sound insulation properties or have poor thermal insulation and sound insulation effects. However, coatings with thermal insulation and sound insulation properties are often used in general engineering and less in household use due to their high price and high construction requirements. 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 microbubbles. Aiming at the difficulty of forming microbubbles in the orifice, pressurization, buffering and pressure control are adopted. The air outlet of the orifice is straight and wide. Stir in an emulsifier ...
