High-ductility medical stone powder and PVC composite tablecloth and preparation method thereof

Abstract

The invention discloses a high-ductility medical stone powder and PVC composite tablecloth. The tablecloth comprises a bottom film and a surface film, wherein the surface film is prepared from the following raw materials in parts by weight: 50-54 parts of PVC, 24-28 parts of plasticizers, 1-2 parts of heat stabilizers, 0.1-0.5 part of lubricants, 50-55 parts of 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 lignin sulfonate, 0.3-0.4 part of azobis(isobutylamidine hydrochloride), 12-13 parts of aluminum glycinate, a proper amount of water, 2-2.5 parts of nano rubber powder, 1.8-2.2 parts of E-44 epoxy resin and 2-2.5 parts of nano-crystalline cellulose. According to the high-ductility medical stone powder and PVC composite tablecloth, E-44 epoxy resin and nano-crystalline cellulose are used for modifying the nano rubber powder; the adhesion strength between the nano rubber powder and PVC is improve; the ductility and the heat resistance of the tablecloth are improved; the rigidity of the tablecloth is not reduced; the tablecloth is stiff and smooth and has adhesion resistance and tearing resistance.

Description

technical field [0001] The invention relates to the technical field of tablecloths, in particular to a high-toughness 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...
