Problems solved by technology

However, since the polyvinyl chloride molecule contains chlorine, when there are active groups such as tertiary chlorine or allyl chloride adjacent to the vinyl chloride, dehydrochlorination reaction is prone to occur and the molecular chain is gradually degraded, and the released hydrogen chloride is toxic. , corrosive, the color of the degraded PVC becomes darker, and the strength decreases
In addition, polyvinyl chloride is easy to penetrate into the fabric tissue, the coating amount is large, and the fabric is easy to harden; the coated fabric is not resistant to dry cleaning and solvents, airtight, and stiff at low temperature
Polyvinyl chloride plasticizer contains a large amount of plasticizer, which is easy to volatilize after forming a coating, and at the same time, insoluble organic pigments also migrate to the surface of the product, contaminating adjacent materials, and the current advertising cloth generally has the problem of being easy to burn , the amount of smoke is large, and there is a large safety hazard in the event of a fire

Abstract

The invention relates to environmental-friendly halogen-free flame-retardant advertisement cloth and a preparation method thereof. The advertisement cloth comprises the following components in parts by weight: 65-75 parts of a polyolefin copolymer, 12-20 parts of polyketone resin, 15-20 parts of polypropylene, 5-15 parts of polyimide coated calcium carbonate, 2-4 parts of titanium dioxide and 3-5parts of nano zinc oxide. Compared with the prior art, the advertisement cloth, namely a polyolefin copolymer film, which is provided by the invention, has good mechanical properties and toughness andhas good adhesion to PP (polypropylene), and compared with conventional PVC (polyvinyl chloride) advertisement cloth, the advertisement cloth is not only easy to print, but also excellent in flame retardance.

Description

technical field [0001] The invention relates to the field of casting flexible composite materials, in particular to an environment-friendly halogen-free flame-retardant advertising cloth and a preparation method thereof. Background technique [0002] Printed advertising cloth is used more and more in the advertising decoration industry. With the springing up of hotels, restaurants, department stores, and various enterprises, inkjet advertising has become an indispensable decoration. Stations, docks, streets, hotels and restaurants can be seen everywhere, and it has become a beautiful landscape of urban and rural construction. The use of inkjet advertising cloth has the characteristics of bright colors, elegant appearance, low investment, quick results, easy hanging and easy replacement, and is widely welcomed by the industry. [0003] At present, most of the advertising cloth or digital printing materials on the market are printed materials covered with PVC raw materials. ...
