Abstract

The invention discloses an elastic primer which is processed with excellent pure acrylic elastic emulsion and imported additives. In addition to the function of general sealing primer, it also has a certain elongation rate. Its unique elastic function can cover the base layer Therefore, it is widely used in the external thermal insulation system of the external wall of the building, effectively solving the problem that the external thermal insulation system is easy to crack.

Description

technical field [0001] The invention relates to an elastic primer, in particular to an elastic primer suitable for the back sealing of an external thermal insulation system of an exterior wall and an easy-to-crack base layer. technical background [0002] Primer is the first coat of paint applied before painting the interior and exterior walls. Its main function is to close the base of the wall and block the capillary pores in the base, so as to effectively isolate the alkali of the substrate and prevent the seepage of alkali from damaging the coating. There are two types of elastic primers: solvent-based and water-based, and water-based primers can be divided into water-emulsion and water-soluble. At present, most of the primers used in the building decoration industry are emulsion primers. Chinese invention patent application 03101178 discloses the technology of "a water-based alkali-resistant elastic primer and its evaluation method". The main raw material of this elas...
