Problems solved by technology

However, the blow-molded halogen-free flame-retardant polypropylene material prepared by it has a relatively large amount of flame retardant, which affects the mechanical properties of the material on the one hand, and on the other hand, the selected flame retardant is weaker due to the gas-phase flame retardant effect. Poor, resulting in problems such as non-self-extinguishing of seat products in physical fires

Abstract

The invention discloses a stadium-dedicated stand seat and its manufacturing method. The stand seat material contains a substrate layer, a wear-resistant anticorrosive coating and an anti-oxidation layer which are successively arranged from the inside out. The substrate layer is a pure magnesium or pure iron substrate. The wear-resistant anticorrosive coating is a metal material intermediate layer containing copper, zinc, tin, silicon and rare metal. The anti-oxidation layer is a surface layer containing an antioxidant additive. The manufacturing method comprises three steps: preparation of the substrate, prefabrication of the wear-resistant anticorrosive coating and prefabrication of the anti-oxidation layer. The stadium-dedicated stand seat is prepared from the three structures, namely the substrate layer, the wear-resistant anticorrosive coating and the anti-oxidation layer. The substrate layer and the wear-resistant anticorrosive coating contain metallic elements and are hard and solid. The anti-oxidation layer is a surface layer, contains flame retardant plastic, and is finally formed by electrolysis. When the stand seat is used in winter, the stand seat will not feel cold like metal. The stand seat provided by the invention has good practicality and security.

Description

technical field [0001] The invention relates to a special stand seat for a stadium, and also relates to a manufacturing method for a special stand seat for a stadium, which belongs to the field of sporting goods and equipment. Background technique [0002] Grandstand seats are chairs specially used in the auditorium of stadiums and song and dance theaters. As early as 2003, the national standard QB / T2601-2003 "Public Seats in Stadiums" was released. The performance is clearly stipulated, and the weather aging resistance requirements of plastic parts are also stipulated. This is because the flame retardants commonly used in plastics are halogen flame retardants. When the plastic is placed outdoors and exposed to sunlight, not only the flame retardancy will decrease, but also the relative aging performance will deteriorate, the mechanical properties will decrease, and it will easily fade. [0003] As far as polypropylene is concerned, the most commonly used flame retardants a...
