Preparation method of damp-proof flame-retardant corrugated paper case

Abstract

The invention discloses a preparation method of a damp-proof flame-retardant corrugated paper case. The outer side surface and inner wall surface of the corrugated paper case are uniformly coated withdamp-proof flame-retardant coating layers. The damp-proof flame-retardant coating layers contains a resin mixture, an ethanol water solution, a grease product, chlorinated paraffin, a damp-proof agent, a fireproof agent and a compound stabilizer. The preparation method particularly comprises the following steps: (1) mixing the ethanol water solution with the grease product and chlorinated paraffin, and carrying out ultrasonic high-speed dispersion; (2) adding the damp-proof agent, the fireproof agent and the compound stabilizer, and carrying out ultrasonic high-speed dispersion; (3) finally adding the resin mixture, carrying out ultrasonic high-speed dispersion, and uniformly mixing, so as to obtain the damp-proof flame-retardant coating layers; and (4) spraying the damp-proof flame-retardant coating layers to the outer side surface and inner wall surface of the corrugated paper case. The corrugated paper case with relatively good damp-proof property and flame retardance is prepared from the common raw material components by virtue of a simple and easily-operated method and is low in production cost and high in product benefit.

Description

technical field [0001] The invention belongs to the technical field of carton manufacturing, and in particular relates to a method for preparing a moisture-proof and flame-retardant corrugated carton. Background technique [0002] Carton (English carton or hard paper case): It is the most widely used packaging product. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. As an indispensable part of modern logistics, packaging cartons bear important responsibilities for packaging, product protection, and aesthetics. The physical performance indicators of packaging cartons become the basis for their quality evaluation. [0003] The national standard for corrugated boxes is GB6543-86 "corrugated boxes". Corrugated cardboard is made by bonding face paper, inner paper, core paper and corrugated paper processed into corrugated corrugated. According to the needs of commodity packaging, corrugated...
