Abstract

The invention belongs to the field of polymer synthesis and particularly relates to a composition for preparing sponge powder puff and a preparation method of the composition. The composition consists of prepolymer ingredients and foaming agent ingredients according to a mass ratio being 100:(50-100), wherein the prepolymer ingredients are prepared from polyether polyol, reaction type hardening agents and toluene di-isocyanate through reaction, NCO is 5.5 to 7.0 percent, and the foaming agent ingredients consist of distilled water and organic silicon surfactants. The preparation method comprises the steps that the polyether polyol and the reaction type hardening agents are placed in a reaction kettle for dehydration, the temperature reduction is carried out, toluene di-isocyanate is added, the temperature rise reaction is carried out, and materials are discharged and are stored in a sealed way; the distilled water and the organic silicon surfactants are mixed, the uniform stirring is carried out, and the mixture is stored in a sealed way; and the prepolymer ingredients and the foaming agent ingredients are uniformly mixed and are cast into a mold for curing, and products are obtained. The sponge powder puff prepared by the composition has the advantages that excellent hydrophily and the hand feeling comfort are realized, the bubble holes are fine, dense and uniform, the powder affinity performance is high, and the use is convenient. The preparation method is simple, and the operation is easy.

Description

technical field [0001] The invention belongs to the field of polymer synthesis, and in particular relates to a composition for preparing a sponge puff and a preparation method thereof. Background technique [0002] The powder puff is one of the cosmetic products that people often use in modern society. It is not only small and beautiful, but also easy to use. It is especially favored by modern women and has almost become a necessary product for their daily life. The preparation materials of the puff are also various, and various materials such as cotton, rubber latex, and foamed plastics can be used, and different materials have their own different characteristics. [0003] The design form of the puff has a great influence on its use performance, so most patents are also aimed at how to improve the design form to achieve the purpose of increasing usability. Patent CN201445080U reports a design and preparation method of a rolling powder puff. By adding a handle and a roller,...
