Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0025] 1. A preparation method of a microencapsulated surface-modified flame retardant for imitation mussel materials
[0026] A preparation method of a mussel-like material microencapsulated surface-modified flame retardant, comprising the following steps:
[0027] Step 1: Weigh 20g of 38% formaldehyde solution, 7g of melamine, 7g of urea, 2g of sodium carbonate, and 120ml of deionized water in a container, and heat it in a water bath to 90°C. After the melamine is completely dissolved, heat-preserve, stir and reflux for 1 hour to obtain urea-formaldehyde Modified melamine resin prepolymer;
[0028] Step 2: Weigh 300g of ammonium polyphosphate (abbreviated as APP, ...

Abstract
The invention relates to the technical field of microencapsulated flame retardants and particularly relates to a preparation method of a microencapsulated surface modified flame retardant made from amussel-imitating material. The flame retardant is prepared from components of a formaldehyde aqueous solution, melamine, urea, sodium carbonate, ammonium polyphosphate, lauryl sodium sulfate, gallotannic acid and the like according to the preparation method. By taking the mussel-imitating material represented by gallotannic acid as a substance for coating the surface of the flame retardant, microencapsulation is formed on the surface of the flame retardant to modify the surface of the flame retardant, so that the compatibility of each other is improved. Meanwhile, the mussel-imitating materialrepresented by gallotannic acid increases a carbon source for flame retardance by the flame retardant, so that the flame retardant effect is improved.
Description
technical field [0001] The invention relates to the technical field of microencapsulated flame retardants, in particular to a preparation method of a microencapsulated surface-modified flame retardant for imitation mussel materials. Background technique [0002] With the rapid development of my country's economy, polymer materials are widely used, and thermosetting resins have been widely used in various fields. As a thermosetting plastic, epoxy resin is popular because of its excellent properties. The cured epoxy resin has good physical and chemical properties, it has excellent bonding strength to the surface of metal and non-metal materials, good flexibility, small set shrinkage, high hardness, good dielectric properties, and the finished product It has good dimensional stability, is stable to alkali and most solvents, and is resistant to chemical corrosion, so it is widely used in national defense and other agencies for impregnation, pouring, lamination, coating, adhesiv...
