Heat-resistant medical stone powder PVC (polyvinyl chloride) composite tablecloth and preparation method thereof

Abstract

The invention discloses a heat-resistant medical stone powder PVC (polyvinyl chloride) composite tablecloth which comprises a base 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 plasticizer, 1-2 parts of heat stabilizer, 0.1-0.5 part of lubricant, 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 lignosulfonate, 0.3-0.4 part of azodiisobutylamidine and hydrochloride, 12-13 parts of aluminum glycinate, a right amount of water, 2-2.5 parts of flaky carbon powder, 3-4 parts of graphene microsheet and 2-2.5 parts of NaA molecular sieve. The medical stone powder added to the surface film of the tablecloth can emit calcium, iron, sodium and other minerals, and is beneficial to the human body. The flaky carbon powder, graphene microsheet and NaA molecular sieve enhance the heat resistance, lubricating property, acid / alkali resistance and antistatic property of the tablecloth.

Description

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