Embodiment Construction

[0012] A microcapsule fly ash-based flame retardant consists of the following steps:

[0013] a. Remove large particles - 1 ton of commercial fly ash (first-grade ash) is passed through a 1000-mesh sieve to remove large particles; 858Kg of fine ash is obtained.

[0014] b. Activate fly ash—add 800Kg of water to the reaction tank and adjust the pH value to 3-4.5 with acetic acid, pour the above fly ash into the reaction tank, start stirring and heat up to 85 degrees Celsius and add 0.8Kg of sodium lauryl sulfate Insulation continued and stirred for 10 hours;

[0015] c. Squeeze and dry the fly ash completed in step b and send it to a 15M high drying tower for air-drying at a temperature of 125 degrees Celsius, and dry it with hot air for use;

[0016] d. Prefabricated capsules - 1000 parts of 0.1% polyacrylamide solution, add 50 parts of cyanuric acid, 0.5 parts of polyhydromethyl silicone oil, 5 parts of phosphoric acid and 0.1 part of coupling agent to make a liquid.

Abstract

The invention provides a manufacture method of a microcapsule flyash based fire retardant. The manufacture method comprises the processing steps of a, removal of large particles, b, activation of flyash, c, drying under hot-blast air, and d, prefabrication of capsules. The fire retardant is low in producing cost, is given the common advantages of organic and inorganic fire retardants, integrates the functions of melting, fire retarding and smoke removing, and can be widely applied to various hard organic foam products.

Description

technical field [0001] The invention relates to a method for manufacturing a microcapsule fly ash-based flame retardant. Background technique [0002] The flame retardant of fly ash applied to polymer materials has the characteristics of self-extinguishing, smoke elimination, high temperature resistance and low cost. However, the unmodified fly ash is incompatible with the interface phase of organic materials, the amount of addition in foam materials is limited, and it is easy to cause problems such as hole breaking and foaming that affect material properties. Microcapsule fly ash-based flame retardant has the excellent properties of fly ash gunpowder smoke flame retardancy, and has a very good compatibility interface phase. When applied to organic rigid foam materials, it will not only not destroy the foam structure but also significantly improve the material strength. . Contents of the invention [0003] The purpose of the present invention is to provide a method for m...
