Embodiment 1

[0078] Add the first part of tap water (1) and Bentone™ EW to a 2.5 liter vessel (150 mm in diameter) fitted with dispersing impeller blades of 100 mm in diameter, maintaining a stirring speed of 500-1000 rpm. Stirring time was continued for approximately 5 minutes until a homogeneous dispersed phase formed without significant agglomeration. Under agitation, the ingredients were added to the mixture in the order listed in Table 1, the amounts of the Part B ingredients also being listed. Add Storflam™ ZAH slowly over 3 minutes. When all ingredients are added to the container, mix at 2000-3000 rpm for fifteen minutes at high speed to evenly disperse the Part A and Part B mixture and form a grind. The components of part C were added in order as shown in Table 1, and at the same time, the Heidolph stirrer equipped with a 100 mm diameter stirring blade was stirred at a slow speed of 350 rpm until a uniform concentration was obtained to form the final coating composition.

Embodiment 2、3 and 4

[0080] Examples 2, 3 and 4 follow the same process as described in Example 1, except that the ingredients and amounts used are as shown in Table 1.

Abstract

The invention relates to a halogen-free flame-retardant coating composition which comprises the components: 10-80% of film-forming polymer and 5-70% of inorganic flame-retardant material, and is characterized in that the flame-retardant material comprises flame-retardant filler microparticles and metallic tin benzoate and/or basic metallic tin benzoate, wherein the total PVC (polyvinyl chloride) content in the composition is 75-97%, and the film-forming polymer contains organic silicon resin.

Description

technical field [0001] The present invention relates to flame retardant coating compositions, their preparation and use. Background technique [0002] Coating compositions are commonly used to coat surfaces within buildings, such as walls, ceilings, floors and furniture surfaces. These surfaces are typically coated using brushes, paint rollers, scrubbing pads and spray tools at ambient temperatures of about 5-40°C. Coatings include paints, lacquers and varnishes. These coatings burn in the event of a building fire. [0003] Fires inside buildings and other structures cause material damage and often cause loss of life due to the heat of the flames and the resulting smoke. Coatings on surfaces within buildings are a source of fuel in fires. Of course, such surfaces are often repainted. After many years, the dried coating typically contains ten or more coats. This multi-layered coating, although not the original origin of the fire, apparently prolongs its duration and thu...
