Abstract

The embodiment of the invention discloses a temperature-changeable sponge for powder puffs, and a preparation technology thereof, and belongs to the technical field of polymer materials. The temperature-changeable sponge for powder puffs is prepared from a component A and a component B according to a weight of (1.5-2.5):(0.8-1.2), wherein the component A comprises 35-60 wt% of a filler, 1-3 wt% ofa surfactant, 0.5-3 wt% of an emulsifier, 0.5-1 wt% of a temperature sensitive toner, and the balance of water; and the component B is a hydrophilic polyurethane prepolymer. The temperature-changeable sponge for powder puff, prepared in the embodiment of the invention, has the advantages of good physical properties, low odor level, good environmental protection performance, good shape recovery and good touch feeling, and is suitable for being used in cosmetics.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of polymer materials, in particular to a temperature-changeable sponge for powder puff and a manufacturing process thereof. Background technique [0002] Sponge is a kind of polyurethane foam and belongs to soft polyurethane foam. Due to the porous honeycomb structure, it has excellent softness, elasticity, water absorption and water resistance, and is widely used in sofas, mattresses, clothing, flexible packaging and other industries. [0003] In the process of sponge synthesis, chain length reaction, foaming and cross-linking are the main processes. These reactions are related to the molecular structure, functionality and molecular weight of the raw materials. [0004] At present, most of the sponge production uses the one-step box foaming method. Various raw materials are quickly added to the forming box under high-speed stirring. The chain growth, foaming, crosslinking, and curing react...
