Problems solved by technology

Although these methods can play a certain role in flame retardancy, they are used in a large amount (usually 20-50% of the emulsion), which seriously reduces the physical properties of the polymer emulsion and affects the use function of the polymer emulsion.
If the dosage is reduced, the flame retardant effect will not be achieved

Abstract

The invention discloses flame retardant type high polymer emulsion and a preparation method thereof. The flame retardant type high polymer emulsion consists of the following components in percentage by weight: 75-90% of high polymer emulsion, 3-10% of a flame retardant polymer and 7-15% of ammonium polyphosphate, wherein the high polymer emulsion is pure acrylic emulsion, styrene-acrylic emulsion, silicone acrylic emulsion or acetic styrene-acrylic emulsion; the flame retardant polymer is vinyl chloride-2-ethyl hexyl acrylate, N-(2,4,6-tribromophenyl) maleimide, tetrachlorophthalic anhydride, propylene alkyl (aryl) phosphorothioate or pentachlorobenzene acrylate. The preparation method of the flame retardant type high polymer emulsion comprises the following steps: mixing and uniformly stirring the high polymer emulsion, the flame retardant polymer and ammonium polyphosphate to obtain the flame retardant type high polymer emulsion. Due to the synergistic effects of the flame retardant polymer and ammonium polyphosphate, the flame retardant type high polymer emulsion disclosed by the invention has good flame retardant effect, so that the V-0 flame retardant level or the V-1 flame retardant level can be achieved by only finally using 10-25% of the flame retardant.

Description

technical field [0001] The invention relates to a flame-retardant polymer emulsion and a preparation method thereof. Background technique [0002] Polymer emulsions, such as pure acrylic emulsion, styrene-acrylic emulsion, silicon-acrylic emulsion, vinegar-acrylic emulsion, etc., are widely prepared into coatings and adhesives, which are widely used in construction, packaging, textile, automobile and other industries. However, polymer latex is easy to burn after drying into a film, which does not meet the current requirements for fire protection, safety and environmental protection. [0003] At present, there is a large demand for flame-retardant polymer emulsions in the market, but the flame-retardant technology is not perfect enough. Now the flame retardant of polymer emulsion mainly adopts the method of adding flame retardants, typical ones are: 1. Adding organic flame retardants, such as chlorinated paraffin, hexachlorocyclopentadiene, decabromodiphenyl ether, tetrabrom...
