Abstract

The invention discloses antifouling Chinese medical stone powder PVC composite tablecloth, which comprises a basement membrane and a surface membrane. the surface membrane is prepared from the following raw materials (by weight): 50-54 parts of PVC, 24-28 parts of a plasticizer, 1-2 parts of a heat stabilizer, 0.1-0.5 part of a lubricant, 50-55 parts of Chinese medical stone, 2-2.5 parts of lavender essential oil, 25-27 parts of vinyl acetate, 0.3-0.5 part of sodium hexametaphosphate, 0.4-0.6 part of sodium lignosulfonate, 0.3-0.4 part of azobis(isobutylamidine hydrochloride), 12-13 parts of aluminum glycinate, a proper amount of water, 3-4 parts of polytetrafluoroethylene micropowder, 2-2.5 parts of nano-silica, and 2-2.5 parts of tetrabutyl titanate. By adding Chinese medical stone powder onto the surface membrane of the tablecloth, mineral substances such as calcium, iron, sodium, etc. can be sent out and are beneficial to human body. By the use of polytetrafluoroethylene micropowder, nano-silica and tetrabutyl titanate, the tablecloth has antifouling and waterproof performance and antibacterial property, is scratch resistant, and has long service life.

Description

technical field [0001] The invention relates to the technical field of tablecloths, in particular to an antifouling 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 o...
