Fire-resistant elastic coating

Abstract

The invention discloses a fire-resistant elastic coating. The fire-resistant elastic coating comprises the following components in parts by weight: 2-5 parts of polyester resin, 3.2-6.2 parts of methyl isobutyl ketone, 2.5-3.6 parts of an acrylic emulsion, 3-5 parts of propylene glycol, 5-8 parts of elastic powder, 8-10 parts of quartz sand, 10-12 parts of bentonite and 4-6 parts of talc powder. In such a manner, the fire-resistant elastic coating disclosed by the invention has strong three-dimensional sense, good flexibility, simplicity in components and low cost as well as long flame-retardant time, high tensile viscosity and good fire resistance.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a fire-resistant elastic coating. Background technique [0002] Elastic architectural coatings are based on synthetic resin emulsion, formulated with pigments, fillers and additives. After applying a certain thickness (dry film thickness greater than or equal to 150μm), it has the ability to produce small cracks due to the expansion and contraction (movement) of the base material. flexible functional coatings. This type of coating has the characteristics of rich expressiveness, strong three-dimensional effect, good flexibility, strong plasticity, strong adhesion, scrubbing, acid and alkali resistance, no fading, no peeling, no cracking, easy maintenance and recoating, etc. However, ordinary elastic coatings have poor fire resistance and are easy to fall off under high temperature. Contents of the invention [0003] The main technical problem to be solved by the invention...
