Abstract

The invention discloses lignin-filled foaming slippers and a producing method thereof. The slippers contain 20 to 60 parts of polyvinyl chloride resin, 5 to 20 parts of rubber, 5 to 40 parts of lignin, 4 to 15 parts of a stabilizer, 1 to 7 parts of an external lubricant, 1 to 5 parts of an internal lubricant, 10 to 32 parts of a plasticizer, 1 to 9 parts of a foaming agent, 1 to 7 parts of a foaming regulator, 0 to 80 parts of a filler, 0 to 12 parts of an antioxidant, and 0 to 10 parts of color masterbatch. Compared with the prior art, the lignin-added polyvinyl chloride is subjected to foaming treatment so as to not only effectively decrease the content of the plasticizerbut also make the product soft and comfortable in texture, and possess good resilience and wear resistance. The methodprovided by the invention has an easy producing process, has low requirements for instruments, can save cost, and has good market expectation.

Description

technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to a lignin-filled foamed slipper and a preparation method thereof. Background technique [0002] Slippers are a necessity in people's daily life. With the increasing pursuit of quality of life by consumers, the requirements for wearing comfort and antibacterial and deodorizing effects of slippers are becoming higher and higher. At the same time, more and more people pay attention to environmental protection and sustainability. The problem of sustainable development has brought new challenges to the research and development of sole materials. [0003] Lignin is the second largest biomass resource in the world after cellulose, but it has long been used as waste in the biorefinery industry and paper industry, which not only has a low recycling rate, but also causes serious environmental pollution. Lignin molecules have a unique hyperbranched polyphenol structure, which is...
