Abstract

The invention discloses an underwear chest pad containing a chitin sponge and a preparation method thereof. The raw material comprises the following components by weight: 100 to 150 parts of toluene diisocyanate, 10 to 30 parts of diisocyanate, 0.5-0.8 part of a polymerization catalyst, 0.5 to 8 parts of a flame retardant, 0.5 to 8 parts of a foaming agent, 10 to 30 parts of chitin powder, 120 to150 parts of polyether polyol, and several parts of water. The chitin powder is added to sponge production, so that the sponge contains chitin, the chitin has no repulsive force on cells, has the effect of repairing the cells, and can alleviate allergic skin. At the same time, the chitin has anti-oxidation ability, can activate the cells, prevents cell aging, and promotes cell metabolism, the chitin has a natural bacteriostatic effect and a very-high broad spectrum antibacterial rate, more than 90% of common bacteria cannot survive on chitin fiber, the uniqueness of underwear mold cups is thatthe underwear mold cups are hotbeds for easy breeding of bacteria, and the chitin sponge is very suitable for the underwear mold cups, and thus providing a safety line for female chests.

Description

technical field [0001] The invention relates to the field of underwear brass pads, in particular to an underwear brass pad containing chitin sponge and a preparation method thereof. Background technique [0002] Sponge is a kind of polyurethane foam, which belongs to soft polyurethane foam. Because of the porous honeycomb structure, it has excellent softness, elasticity, water absorption and water resistance, and is widely used in sofas, mattresses, underwear, clothing, flexible packaging and other industries. [0003] Chitin also contains high-efficiency moisturizing ingredients, and its β-glucan can also effectively moisturize the skin. At room temperature, every 100 grams of chitin powder can absorb 200-225 grams of 40wt% sodium hydroxide solution, of which water absorption is About 100 grams. The adsorption value of chitin is related to the concentration of alkali solution and the adsorption temperature. At zero temperature, for 20-30wt% sodium hydroxide solution, eve...
