Anion-containing sponge and foaming method thereof

Abstract

The invention discloses an anion sponge foaming method which comprises the following steps of preparing 4-tert-octylphenol, polyether, polyether polyol, toluene diisocyanate, modified polyether polyol, water, DC5810 silicone oil, 33 percent triethylene diamine solution and stannous octoate; fusing the polyether, tourmaline powder and rear earth; performing mixing and stirring according to the requirements; and after stirring is finished, pouring a mixture into a foaming box. The anion sponge foaming method controls the time condition and the stirring condition of soaking decomposition and canproduce foamed sponge with high anion content. The invention also provides anion foamed sponge prepared by adopting the method.

Description

technical field [0001] The invention relates to the field of sponge foaming technology, in particular to an anion sponge and a foaming method thereof. Background technique [0002] Charged particles formed by atoms losing or gaining electron pairs are called ions, and negative ions are ions with one or more negative charges called "negative ions", also known as "anions". It has the reputation of "air vitamin". Some people think that it plays an important role in the life activities of the human body just like food vitamins. Some people even think that negative ions in the air are related to longevity and call it "longevity ion". Dust, dust, etc. in the air are positively charged, and negative ions themselves are negatively charged, showing negative charge. When negative ions encounter dust and other particles in the air, the positive and negative attract each other, making the dust and other particles agglomerate , to increase the weight of dust, etc., so that it falls on t...

Problems solved by technology

[0003] Therefore, people began to add negative ions to the foaming process of the sponge. The sponge produced in this way can play a good role in health care. Ester, fibers, binders, foaming aids and negative ion powder are mixed in a ratio of 5:2:1:1:1 and foamed in a foaming cylinder for 10-12 hours at a temperature of 60- A kind of negative ion sponge made at 80°C. Although this technology is made by mixing various raw materials, the specific composition of the raw materials is not clear, and the processing of negative ion powder is very easy to fail, resulting in the failure to release negative ions in the finished product.
