Abstract

The invention discloses a flame-retardant plastic paint which mainly is prepared from the following raw materials in parts by weight: 20 parts of water-based acrylic resin, 10-20 parts of polystyrene, 2-12 parts of polylactate, 4-10 parts of zinc stearate, 1-5 parts of sodium dodecylsulfate, 2-8 parts of dibutyl phthalate, 6-12 parts of pentaerythritol, 0.5-0.9 part of pigment and 1-7 parts of inorganic filler. The invention also discloses a preparation method of the flame-retardant plastic paint. Compared with the prior art, the flame-retardant plastic paint has the advantages of low cost, simple technique, high adhesive force, excellent adhesiveness and longer fire resistance time; and the carbonization layer formed during combustion has thick inside, is firm and compact, and has obviously higher flame-retardant effect.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a flame-retardant plastic coating with excellent comprehensive performance and a preparation method thereof. Background technique [0002] Flame retardant coatings are currently a hot research topic in the coatings industry. Existing flame-retardant coatings are mainly flame-retardant coatings suitable for the surface of metal materials, wood surfaces or building materials. Compared with metal materials, wood materials or building materials, plastic materials have certain limitations in the selection of coatings, mainly Since plastic materials have high requirements for coating adhesion, they also have certain requirements for flame retardancy. [0003] At present, traditional plastic coatings have some defects, such as insufficient coating adhesion, easy layering, peeling off, short service life, and poor flame retardancy. Contents of the invention [0004] Purpo...
