Magnetic nanoparticle latex product production process

Abstract

The invention discloses a magnetic nanoparticle latex product production process. The process is characterized by including steps: firstly, preparing magnetic nanoparticle dispersoid according to a co-precipitation method, and subjecting to leaching and extraction; secondly, adding an alkaline botanic castor oil protective agent into magnetic nanoparticles to obtain magnetic nanoparticle dispersion liquid which can be well mixed with natural latex; finally, taking the natural latex as a raw material, uniformly adding the magnetic nanoparticle dispersion liquid in a natural latex prevulcanization or compounding process, dispersing into the natural latex, and performing bubbling, gelatinization, aging, dewatering and drying to obtain a finished product. The process is specially applied to production of high-quality magnetic nanoparticle latex products, technical simplicity is achieved, and the produced magnetic nanoparticle latex products have a function of magnetic therapy while high resilience and breathability of latex sponge are kept.

Description

technical field [0001] The invention relates to a production process of natural latex products containing magnetic nanoparticles. Background technique [0002] In recent years, with the improvement of people's living standards and the increasing awareness of health, more and more high-end bedding has been favored by consumers. Latex pillows and mattresses are made of natural latex extracted from rubber trees planted in tropical areas. They are produced through centrifugal concentration, foaming, gelling, aging, dehydration, and drying. They are soft, breathable, durable, and long-lasting. Elastic, with ergonomic all-round support to achieve healthy, comforting and comfortable sleep. In order to increase the health function of latex products, some health care materials such as negative ion powder, magnet powder, ocher powder, etc. are often added in the production process, but magnetic particles such as magnet powder are generally large and insoluble in water. First of all,...

Problems solved by technology

In order to increase the health function of latex products, some health care materials such as negative ion powder, magnet powder, ocher powder, etc. are often added in the production process, but magnetic particles such as magnet powder are generally large and insoluble in water. First of all, it is difficult to get uniform dispersion in the natural latex stock solution, and it is also prone to agglomeration; second, the direct addition of magnetic particles to natural latex will have a negative impact on the material properties of the natural latex stock solution, so the produced latex products with magnetic functions tend to be There are different quality problems, and it is difficult to meet the requirements of the industry standard for latex products that is about to be introduced
