Abstract

The invention discloses a primer which is refined from polymer elastic emulsion, inorganic binders, functional additives, and pigments and fillers. Its unique high-elastic formula design has amazing resilience enough to expand and shrink with the base layer's heat, thereby Resists cracking. Its unique elastic function is used in conjunction with fluorocarbon paint, which can solve the common problem that fluorocarbon paint is easy to crack, which is beneficial to its decoration, so that the wall is cracked but the paint is not cracked, and the wall can be protected for a long time.

Description

technical field [0001] The invention relates to a primer, in particular to a primer suitable for the back cover of fluorocarbon paint. 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 primers: solvent-based and water-based, while water-based paint can be divided into water-based 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 anti-alkali primer and its evaluation method". The main raw material of this primer is styrene-copolymer emulsion. Due to the low film-forming density and weak permeability to the base material o...
