example 1

[0014] First, put any size of paper (corner waste) or waste paper into a shredder and crush it into shredded paper powder with a particle size of <1mm, then stir the paper powder in a mixer and add binder latex glue (also known as paper tube glue) , Ningbo Zhenhai Yongcure Factory), its weight ratio is paper powder: latex glue = 1: 0.5, then the paper powder is extruded in an extruder, and finally dried in a drying oven at a temperature of 50 ℃.

example 2

[0016] The particle size of the paper powder is <0.5mm, the weight ratio of the paper powder and the latex glue is paper powder: latex glue=1:0.4, the drying temperature is 45° C., and the rest are the same as in Example 1.

example 3

[0018] The particle size of the paper powder is <0.1mm, the weight ratio of the paper powder and the latex glue is paper powder: latex glue=1:0.3, the drying temperature is 40° C., and the rest are the same as in Example 1.

Abstract

A technology for manufacturing paper board or paper pipe with powdered paper includes pulverizing used paper to obtain powdered paper, mixing it with adhesive, stirring, die pressing, and baking at 40-50 deg.C.

Description

technical field [0001] The invention relates to a method for preparing paper tubes and cardboards from paper powder, in particular to a method for preparing paper tubes and cardboards by crushing waste paper into powder. Background technique [0002] Chinese patent 94110909.7 discloses a method for making cardboard and paper tubes. The method is to alternately stack multi-layer paper and multi-layer plastic paper, then make them into shapes, and then put them into a constant temperature furnace to heat and keep them warm. This invention can Make full use of waste paper and waste plastic paper to make cardboards and paper tubes, and can derive a large number of other products. The method is simple and practical, and the products produced have low cost and good strength. [0003] However, the above method also has the disadvantages that the shredded paper cannot be fully utilized and the production cost has room for further reduction. Contents of the invention [0004] The ...
