Antibacterial medical stone meal PVC (Polyvinyl Chloride) composite table cloth and preparation method thereof

Abstract

The invention discloses antibacterial medical stone meal PVC (Polyvinyl Chloride) composite table cloth. The antibacterial medical stone meal PVC composite table cloth comprises a basement 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 vinyl acetate, 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, a proper amount of water, 2 to 2.5 parts of rice bran wax, 1.3 to 1.5 parts of herba speranskiae tuberculatae extract and 2 to 2.5 parts of nanosilver. According to the antibacterial medical stone meal PVC composite table cloth disclosed by the invention, the medical stone meal is added on the surface membrane of the table cloth, so that the antibacterial medical stone meal PVC composite table cloth can give out mineral substances such as calcium, iron and sodium, is beneficial to a human body and has good bacteria resistance and insect resistance; by using the rice bran wax, the herba speranskiae tuberculatae extract and the nanosilver, the bacteria resistance of the table cloth is improved, and the water resistance is improved.

Description

technical field [0001] The invention relates to the technical field of tablecloths, in particular to an antibacterial medical stone powder PVC composite tablecloth 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 new type...
