Problems solved by technology

[0004] As a polymer organic foam material, the flammability of polyether polyurethane sponge has become an important issue that threatens its safety. Therefore, some flame retardant modifications have been made to polyether polyurethane sponge in the existing market; such as China Patent publication number CN102643404A, the patent publication date is August 22, 2012. The patent named a slow rebound polyether polyurethane sponge discloses a flame retardant modification for the flammability of polyether polyurethane sponge. , adding a sulfonate flame retardant to the formula of polyether polyurethane sponge for flame retardant modification, although its flame retardant effect has been improved to a certain extent, but due to the single effect of the added flame retardant, its flame retardant The effect is still difficult to meet the public's requirements for the flame retardant effect of polyether polyurethane sponge

Abstract

The invention belongs to the technical field of space cotton pillows, and discloses a slow recovery latex space cotton pillow. The pillow comprises a pillow inner and a natural latex layer; the pillowinner is formed by a polyether urethane sponge with anti-flaming and antibacterial functions, the natural latex layer is formed by foaming pure natural latex, the natural latex layer wraps the pillowinner, and the thickness of the natural latex layer is 2-5 mm. The slow recovery latex space cotton pillow has the good surface touch and has the slow rebound resilience, proper hardness and good anti-flaming effect; special antibacterial treatment is performed in holes of the polymeric sponge in the slow recovery latex space cotton pillow, and the problem that bacteria and other harmful microbesare likely to be bred/enriched in the sponge holes is solved.

Description

Technical field [0001] The invention relates to the technical field of space cotton pillows, in particular to a slow rebound latex space cotton pillow. Background technique [0002] With the improvement of people’s living standards, more and more attention is paid to the quality of sleep, and pillows are also more and more important as important sleeping appliances. Polyurethane has both the elasticity of rubber, the strength of plastics and the excellent processing performance. It is used to prepare polyurethane slow-rebound foam (soft polyurethane foam). Space cotton pillows made from polyurethane as a raw material are becoming more and more popular because of their slow rebound characteristics. However, the polyurethane sponge used as a raw material has a series of problems. [0003] Flexible polyurethane foam can be divided into polyester flexible foam and polyether flexible foam based on the polyol raw materials used. Polyether polyurethane is an open cell structure with the ...
