Modified film cloth and preparation method thereof

Abstract

The invention discloses a modified film cloth and a preparation method thereof. The film cloth comprises a film cloth body and an anti-fouling anti-bacterial coating, wherein the anti-fouling anti-bacterial coating is applied on the outer surface of the film cloth body, the composition raw materials of the film cloth body comprises, in parts by weight, 30-40 parts of natural plant fiber, 10-20 parts of chitin, 10-20 parts of chitosan, 1-5 parts of a gelling agent, 1-5 parts of a toughening agent, 1-3 parts of a flame retardant, and 1-3 parts of an antioxidant, the composition raw materials of the anti-fouling anti-bacterial coating comprise, in parts by weight, 50-60 parts of methyl phenyl silicone resin, 1-5 parts of a mould inhibitor, 1-3 parts of silver chloride powder, 1-5 parts of a cross-linking agent, and the balance deionized water. The invention relates to the technical field of building films. According to the modified film cloth and the preparation method thereof, the coating of a layer of the anti-fouling layer on the outside of the film cloth can be realized, the anti-fouling layer and the film cloth itself can be well compounded together to form a whole, the purpose that the anti-fouling and antibacterial ability of the film cloth is improved while ensuring good mechanical properties of the film cloth itself is achieved.

Description

technical field [0001] The invention relates to the technical field of architectural membranes, in particular to a modified membrane cloth and a preparation method thereof. Background technique [0002] Inflatable structure, also known as "inflatable membrane structure", refers to the structure of the house formed by filling the film product made of polymer material with air. The inflatable structure can be divided into air-bearing membrane structure and inflatable membrane. Structure (or air-ribbed membrane structure), the most typical inflatable membrane structure building is the Water Cube. The inflatable membrane structure of the inner and outer facades of the Water Cube consists of 3065 air pillows, the largest reaching 70 square meters and covering an area of ​​10. It is the largest inflatable membrane structure project in the world and the only large-scale public building completely enclosed by membrane structure. The inflatable membrane structure has single layer, do...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a modified membrane cloth and its preparation method, which solves the problem that the existing improvement will reduce the toughness and other mechanical properties of the membrane cloth itself, so that the long-term use of the membrane cloth cannot be guaranteed, and the Coating a layer of anti-pollution layer on the outside of the membrane cloth, and making the anti-pollution layer and the membrane cloth itself well combined to form a whole, can not achieve the good mechanical properties of the membrane cloth itself, while improving the membrane cloth. The purpose of anti-pollution and antibacterial ability cannot guarantee the anti-pollution and antibacterial ability of the membrane cloth, which greatly shortens the service life of the membrane cloth.
