Friction, hair-falling and dust-falling resistant wet pressure paper pulp holder and production method thereof

Abstract

The invention provides a friction, hair-falling and dust-falling resistant wet pressure paper pulp holder and a production method thereof. The method comprises the following steps: 1, sequentially carrying out beating, pulp formation and molding treatment on a raw material and water to produce a wet blank; 2, spraying a protection coating on the wet blank; and 3, carrying out hot pressing and subsequent treatment on the protection coating sprayed wet blank to obtain the finished wet pressure paper pulp holder. A spraying technology is carried out in the production process of the wet pressure paper pulp holder to form the smooth and wear-resistant protection coating on the surface of the wet pressure paper pulp holder, so scratches, hair-falling and other phenomena of the paper pulp are avoided in the packaging transportation test and practical transportation process, the problem of pollution of dusts caused by friction and disengagement of plant fibers from a paper pulp holder main body to packaged internal space environment is solved, and fault, damage or discard risks caused by invasion of the dusts and the plant fibers are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of pulp technology, and relates to a wet-pressed pulp tray and a preparation method thereof, in particular to a wet-pressed pulp tray which is resistant to friction and prevents lint and dust from falling off, and a preparation method thereof. Background technique [0002] Pulp tray, also known as pulp molding, is made of carton scraps, newsprint and white pure wood pulp as raw materials, after pulping and blending into a certain proportion of slurry, on the customized CNC mold according to product design, after vacuum Environmentally friendly paper products of different types and uses formed by adsorption molding and post-drying. [0003] Through decades of development, pulp trays have been widely used in packaging applications, and the technology is relatively mature, including dry-pressed pulp trays and wet-pressed pulp trays. The dry-pressed pulp tray itself is relatively rough. In terms of packaging ap...

AI Technical Summary

Problems solved by technology

[0010] In view of the fact that the existing wet-pressed pulp tray will vibrate and rub against the product during the packaging and transportation test and actual application, resulting in scratches and lint, which will cause the pulp tray to dye the packaged goods, pollute the internal space environment of the packaging, and high-end brand environmental protection packaging The concept of the problem is not coordinated, which seriously affects the packaging effect and other problems. The invention provides a wet-pressed pulp tray which is resistant to friction and prevents lint and dust and its preparation method
