Description
Technical field
The present invention relates to sponge product technical field, specially a kind of rush dormancy memory foam preparation method containing lavender.
Background technique
Memory foam refers to the polyetherurethane foam sponge with low resilience mechanical property, belongs to extraordinary sponge, by Europe
The exploitation of continent a company, for English namespace uri MEMORY FOAM, memory foam is its literal translation, domestic also referred to as slow-recovery sponge,
Space zero pressure, space cotton, TEMPUR Thailand Poole material, low bounce-back material, viscoelastic sponge etc., sponge product is widely used in
In furniture item, and it then will use the gel memory foam with low resilience effect as packing material, mesh in medium-to-high grade furniture
Preceding main species are exactly polyethers serial foaming and polyurethane moulding form full series, and low resilience, this is one and aims at slow rebound sponge
The noun of manufacture, in terms of it is meant that mechanical property:, will not be anti-immediately when slow rebound sponge has received external force pressure deformation
Bullet, but delay several seconds time and slowly restore, so if we press slow rebound sponge with hand, it can be seen that the hand of oneself
Print, as slow rebound sponge can remember to oppress its thing shape, the title of " slow rebound sponge " also therefore, low resilience
Sponge low resilience performance Producing reason, mainly since it has special cellular foam structure, air is forced out abscess, bubble
After hole is crushed, although external force has been dispelled, cell wall also has the elastic force of reduction, and since venthole is tiny, air is not
Can immediately return in abscess, abscess can not soon restore shape, and the strength of rebound is suppressed, material deformation restore when
Between be just extended.
And there is heat-transfer effect difference in current sponge products, this furniture for allowing for filling sponge is not suitable for the summer
It is used in its hot weather, this also affects the universal of the furniture of filling sponge material, and current sponge has rebound time mistake
Short, physical property is unstable, easy to oxidize and turn to be yellow and discharge noxious material, and oxidation process is accelerated and discharges peculiar smell, unfavorable
It in environmental protection, is easily deformed, more important current memory foam, which is difficult to, promotees the effect calmed the nerves of sleeping, too especially for many
Busy, the indefinite user of thought, and Lavender complicated component contains tens kinds of compounds, main ingredient have linalool,
Bergamio, cineole, β-ocimenum, terpene -4- alcohol, camphor, different, the contained component difference in the type of lavender, the place of production
Very big, this just determines that their the different market prices, different application ranges and different odor types, Lavender have town
Quiet hypnosis relaxs one's muscles, and relieves fatigue, antibacterial action, reduces the effect of scar, for this purpose, proposing that a kind of rush containing lavender is slept
Memory foam preparation method solves the above problems.
