Compression-resistant flame-retardant carton and preparation method thereof

Abstract

The invention discloses a compression-resistant flame-retardant carton, and particularly relates to the technical field of carton processing. The compression-resistant flame-retardant carton comprises the following raw materials: bamboo pulp, wood pulp, modified straw fibers, modified coconut fibers, a flame retardant, modified diatomite and an auxiliary agent. The straw fibers have good mechanical properties, the straw fibers are pretreated through alkali treatment, active points on the surfaces of the straw fibers can be increased, the dispersity of fiber particles can be improved, then the straw fibers are subjected to graft modification, the mechanical properties of the straw fibers can be improved, the sodium silicate, the carboxy nitrile rubber and the grafted straw fibers are subjected to blending modification, so that the flame retardant property of the straw fibers can be effectively improved; and the coconut fibers are treated by the silane coupling agent and the nano magnesium oxide and then are blended and modified with the polylactic acid and the epoxy coated ammonium polyphosphate, so that not only can the pressure resistance of the coconut fibers be improved, but also the flame retardant effect of the coconut fibers can be improved.

Description

technical field [0001] The invention relates to the technical field of carton processing, more specifically, the invention relates to a pressure-resistant and flame-retardant carton and a preparation method thereof. Background technique [0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes and single-layer cardboard boxes. Cartons exist in various packaging ranges among people, and they almost replace wooden boxes, cloth bags and other packaging forms, and are the best choice for people to package various items. However, there are still certain problems in the existing cartons. For example, in the process of express delivery, even if it is marked to handle with care, some accidents may cause collisions of the cartons, damage the articles in the cartons, and in some In special fields, some flame-retardant cartons are needed, and the current flame-retardant cartons are generally sprayed with some flame retar...

Problems solved by technology

However, there are still certain problems in the existing cartons. For example, in the process of express delivery, even if it is marked to handle with care, some accidents may cause collisions of the cartons, damage the articles in the cartons, and in some In special fields, some flame-retardant cartons are needed, and the current flame-retardant cartons are generally sprayed with some flame retardants on the cartons. This kind of flame-retardant cartons cannot have a good flame-retardant effect and cannot achieve the purpose of flame retardancy.
