Abstract
The invention discloses a kind of memory cushion and preparation method thereof, memory cushion comprises the raw material of following weight portion meter: kymene 0-40 part, magnesium hydroxide 20-40 part, methacrylic acid 10-20 part, ammonium chloride 10-20 part, tributyl phosphate 20-50 part, trimethylolpropane 40-50 part, surfactant 20-30 part. The preparation method of memory cushion: polyamide, magnesium hydroxide, methacrylic acid, ammonium chloride, tributyl phosphate and trimethylolpropane are mixed, be heated to 90-110 DEG C, add surfactant, reaction 30-40min, injection mo(u)lding. Memory cushion of the present invention is through pressing for a long time, indeformable, still keeps original elasticity, and elasticity and restorability are all fine.
Description
Technical field
The present invention relates to a kind of memory cushion and preparation method thereof.
Background technology
Cushion, can allow seat for a long time in clean state, is placed on and above stool, has warming and comfortable effect. The shape of cushion, according to supporting chair designs, mostly is square, circular and oval. Cushion can also be made to animal, personage, fruit and other interesting image, on pattern, also can make with reference to the pattern of the pattern of bedcover in bedroom or sofa, also can independently come out as an article. Cushion small volume, is widely used, but after existing cushion is sat for a long time, flattens and be difficult for recovering, and affects result of use.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of memory cushion is provided, rebound performance is good.
The present invention is by the following technical solutions:
One is remembered cushion, comprises the raw material of following weight portion meter: kymene 0-40 part, magnesium hydroxide 20-40 part, methacrylic acid 10-20 part, ammonium chloride 10-20 part, tributyl phosphate 20-50 part, trimethylolpropane 40-50 part, surfactant 20-30 part.
As preferably, surfactant is stearic acid or neopelex.
The present invention also provides the preparation method of above-mentioned memory cushion, comprise the following steps: polyamide, magnesium hydroxide, methacrylic acid, ammonium chloride, tributyl phosphate and trimethylolpropane are mixed, be heated to 90-110 DEG C, add surfactant, reaction 30-40min, injection mo(u)lding.
Beneficial effect of the present invention: memory cushion of the present invention is through pressing for a long time, indeformable, still keeps original elasticity, and elasticity and restorability are all fine.
