Abstract

The invention discloses a preparation method of a coconut palm fiber foaming mattress. Coconut palm fiber, hexahydrotriazine, isocyanate, triethylenediamine, methyl diisocyanate, triethanolamine, water-soluble silicone oil, pure water, dibutyltin dilaurate, an AC foaming agent, DCP, decabromodiphenyl ether, fatty acid amide, butyl acetate and acetic anhydride are weighed; the preparation method is simple, the cost is low, the maneuverability is strong, the compressive strength is 280-320MPa, the rebound rate is 99% to 99.8%; the tear strength is 5 to 7N / cm, the product is soft, high in durability, not easy to collapse and deform, and high in supporting performance; the elongation is 200 to 240%, and the mattress is antibacterial, mildew-proof, good in process stability, long in service life, and not easy to eat by moth; the tensile strength is 230 to 330MPa, the bond strength is 220 to 280MPa, and the raw material is wide in source, and can be widely produced and continue to replace existing materials.

Description

technical field [0001] The application belongs to the field of mattress materials, in particular to a method for preparing a coconut palm fiber foam mattress. Background technique [0002] Mattress is an item between the human body and the bed to ensure consumers get a healthy and comfortable sleep. Mattresses are made of various materials, and mattresses made of different materials can bring different sleep effects to people. [0003] Existing mattresses are made of mountain palm or coir with modern adhesives. It has the characteristics of environmental protection. The difference between mountain palm and coconut palm fiber is that mountain palm has excellent toughness, but its supporting force is insufficient. The overall supporting force and durability of coconut palm are better, and the force is even, and it is harder than mountain palm. [0004] Palm mattresses are woven from coconut palm fibers and are generally hard or slightly soft. The price of this mattress is...
