Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the examples.

[0023] Sawdust refers to the sawdust and shaving powder left over from wood processing.

[0024] Crops leftovers, such as Husang branches and roots, cotton stalks, rape stalks, peanut shells, reeds, straw, and wheat stalks. The following examples use cotton stalks, rape stalks, and peanut shells, and the three are matched in a weight ratio of 1:1:1.

[0025] 1. Preparation of materials: firstly prepare the sawdust and crop leftovers according to the ratio of 4:6, and stir them evenly to prepare the main material mixture for later use, and pave the veneer bark made by rotating and cutting poplar trees for later use;

[0026] 2. Mixing material: Put the prepared main material mixture and adhesive into the glue mixer in a ratio of 9:1 and stir evenly;

[0027] 3. Pavement: Apply a layer of adhesive on the upper surface of the veneer and spread it on the steel plate, and the steel ...

Abstract

The invention discloses a manufacturing method of packaging box plates. The manufacturing method includes the steps of preparing materials, including the main material crop offcut; pouring wood chips, glue, and the crop offcut into a glue blender, and mixing well; laying, namely coating a veneer with a glue layer prior to laying the veneer on a steel plate, and making sure the glue side faces upside; placing the steel plate on a conveyor belt; evenly laying mixture on the veneer of the steel plate by a spreader; laying another veneer with the lower surface glued, on the mixture; pressurizing and solidifying, namely heating and pressurizing a laid plate blank in a hot press, at the temperature of 140-170 DEG C, holding the pressure for 6-10 minutes for solidification and forming; stripping and trimming, namely stripping the solidified plate and trimming the plate. Specifically, the materials include, by weight, 30-40% of the wood chips, 8-10% of the glue, and the balance of the crop offcut. The glue is dicyclopentadiene modified unsaturated polyester resin glue. Therefore, environment protection is achieved.

Description

Technical field [0001] The invention involves the manufacturing method of packaging box plates. Background technique [0002] At present, the packaging box plate market mostly adopts plywood and particleboard.Adopting plywood, although the cost is not high, it is easy to pollute the environment and waste resources.The use of the particleboard, the static tune strength is not high, and a large amount of wood resources are required, and the process requirements are high.According to a public document with the patent application number 200510031455.0, it publicly disclosed a plate material and its manufacturing method. The board has two sides of the enhanced layer and the intermediate structure layer.The structure layer is composed of mineral powder and lightweight material. The enhanced layer has glass fiber mesh and adhesive. Although it can achieve the effect of enhancement and environmental protection, its process is complicated, inconvenient, and high cost.
