Abstract

The invention provides a method for preparing a microcapsule adhesive used for 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 the melamine wall material to form a capsule by polycondensation, thus preparing the microcapsule adhesive used for the coating. The invention also discloses a microcapsule adhesive 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 and has large market potential.

Description

technical field [0001] The invention belongs to the preparation of a novel microcapsule adhesive for thermal insulation and sound insulation architectural coatings. Background technique [0002] At present, adhesives for construction and decorative coatings at home and abroad generally do not have thermal insulation and sound insulation properties or have poor thermal insulation and sound insulation effects. For some architectural coatings, materials with good thermal insulation and sound insulation effects are added, but due to the poor thermal insulation and sound insulation effect of the adhesive, the thermal insulation and sound insulation effect of the paint coating is not good. Therefore, it is imperative to develop adhesives for architectural coatings with good thermal insulation and sound insulation effects. 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 an...
