Medical stone powder-PVC (Polyvinyl Chloride) composite tablecloth capable of emitting negative ions and preparation method thereof

Abstract

The invention discloses medical stone powder-PVC (Polyvinyl Chloride) composite tablecloth capable of emitting negative ions. The medical stone powder-PVC composite tablecloth capable of emitting the negative ions comprises a bottom membrane and a surface membrane, wherein the surface membrane is prepared from the following raw materials in parts by weight: 50 to 54 parts of PVC, 24 to 28 parts of plasticizer, 1 to 2 parts of heat stabilizer, 0.1 to 0.5 part of lubricating agent, 50 to 55 parts of medical stone, 2 to 2.5 parts of lavender essential oil, 25 to 27 parts of acetic acid vinyl ester, 0.3 to 0.5 part of sodium hexametaphosphate, 0.4 to 0.6 part of sodium lignin sulfonate, 0.3 to 0.4 part of azobis(isobutylamidine hydrochloride), 12 to 13 parts of aluminum glycinate, appropriate amount of water, 1.3 to 1.5 parts of nanometer iron oxide, 2.5 to 2.9 parts of nanometer tourmaline powder, and 1 to 1.4 parts of nanometer aluminum oxide. According to the medical stone powder-PVC composite tablecloth capable of emitting the negative ions provided by the invention, the nanometer iron oxide, the nanometer tourmaline powder and the nanometer aluminum oxide are used, so that an electromagnetic wave can be absorbed, the negative ions and a far infrared ray can be emitted, the tablecloth is good for human health, and the wear resistance and the heat resistance of the tablecloth are also improved.

Description

technical field [0001] The invention relates to the technical field of tablecloths, in particular to a PVC composite tablecloth emitting negative ions medical stone powder and a preparation method thereof. Background technique [0002] PVC tablecloth is a kind of daily necessities. The existing PVC tablecloth is generally made of PVC film and non-woven fabric through glue bonding. It is mainly used for laying dining table, traveling floor and other purposes. It is easy to clean, convenient and practical. However, the existing PVC tablecloths have the following disadvantages during use, which are not environmentally friendly, easy to have peculiar smell, and not durable enough. [0003] Rich Mineral Paper (RMP) is also called environmental protection paper. It uses calcium carbonate, the most abundant mineral resource in the earth's crust, as the main raw material, and uses polymer materials and various inorganic substances as auxiliary materials. Modification technology, a ...
