Abstract

The invention discloses alpha-cyclodextrin modified medical stone powder and PVC composite tablecloth, which comprises a bottom film and a surface film. The surface film is prepared from the following raw materials in parts 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 medical stones, 2-2.5 parts of lavender essential oil, 25-27 parts of acetic acid vinyl ester, 0.3-0.5 part of sodium hexametaphosphate, 0.4-0.6 part of sodium lignin sulfonate, 0.3-0.4 part of azobis(isobutylamidine hydrochloride), 12-13 parts of aluminum glycinate, a proper amount of water, 3-4 parts of alpha-cyclodextrin, 0.5-0.7 part of protease and 2-2.5 parts of an ethyecellulose terpilenol solution. According to the alpha-cyclodextrin modified medical stone powder PVC composite tablecloth disclosed by the invention, alpha-cyclodextrin is used to adsorb protease, and proteins can be decomposed, so that the tablecloth is easy to clean; and moreover, water resistance is improved, and the ethylcellulose terpilenol solution is used for coating and modification, so that strength and toughness of the tablecloth are improved.

Description

technical field [0001] The invention relates to the technical field of tablecloths, in particular to an α-cyclodextrin modified 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, ...
