Abstract

The invention relates to the technical field of cosmetic brush materials, and particularly discloses a flame-retardant cosmetic brush wire and a preparation method thereof. The flame-retardant cosmetic brush wire is prepared from the following raw materials in parts by weight: 100-150 parts of epoxy resin, 20-30 parts of acrylic acid, 10-25 parts of bentonite, 3-13 parts of a flame retardant, 10-20 parts of a plasticizer, 30-50 parts of a curing agent and 5-15 parts of a cross-linking agent. The flame retardant is prepared from the following raw materials in parts by weight: 2-10 parts of solid superacid, 20-40 parts of ammonium polyphosphate and 10-25 parts of silicon dioxide. The preparation method comprises the following steps that firstly the acrylic acid is mixed with the epoxy resin, melt blending is carried out with other raw materials, and finally wire drawing molding is carried out to obtain the cosmetic brush wire. The flame-retardant cosmetic brush wire has the advantage of being good in flame-retardant effect.

Description

technical field [0001] The present application relates to the technical field of cosmetic brush materials, and more specifically, it relates to a flame-retardant cosmetic brush filament and a preparation method thereof. Background technique [0002] Cosmetic brushes are one of the most commonly used cosmetic tools in the field of cosmetics. Cosmetic brushes include a brush body and a brush head. The brush head is composed of cosmetic brush filaments. When making up, the brush head is used to dip the cosmetics and apply them to the makeup area. Finish with makeup. [0003] The main raw material of cosmetic brushes is animal hair or rayon. In order to reduce the use of animal hair, rayon is used more and more. Epoxy resin is used as a raw material for cosmetic brush filaments due to its good chemical stability, processability, and low cost. Epoxy resin, plasticizer, curing agent, etc. are melted and then drawn to prepare cosmetic brush filaments. [0004] The limiting oxygen...
