Three-dimensional recycled paper pulp molded product material and preparation method

Abstract

The invention discloses a three-dimensional recycled paper pulp molded product material which is characterized by being prepared from the following components in parts by weight: 60-90 parts of regenerated plant paper pulp (based on dry fibers), 5-10 parts of acrylic emulsion (with the solid content of 50%), 0.1-0.5 parts of a soap deinking agent, 0.01-0.03 parts of a volatile agent, 2-4 parts ofrosin size, 0.1-1 part of a dispersing agent, 0.1-0.3 parts of pigment, 0.5-1 part of waterborne ceramic coating and 10-20 parts of water. The invention further discloses a preparation method of the three-dimensional recycled paper pulp molded product. The formula and the preparation method of the material are matched with each other. The preparation process is simplified, and the comprehensive performance of the material and the product is greatly improved. Ink and adhesive tape plastic doped in paper pulp can be removed, and later coloring of paper and plastic is facilitated. The situation that the structure of the paper and plastic is unstable due to the fact that broken paper pulp of the plastic is separated is avoided. The surface of the paper and plastic is sprayed with waterborne ceramic coating after the paper and plastic are manufactured, a paper and plastic product is not prone to deformation and damage, and the service life of the paper and plastic product is prolonged.

Description

technical field [0001] The invention relates to the technical field of recycled pulp, in particular to a material and a preparation method of a three-dimensional recycled pulp molded product. Background technique [0002] Pulp molding is a three-dimensional papermaking technology. It uses pulp as raw material to shape paper products of a certain shape on the mold. It is completed by pulping, adsorption molding, drying and shaping. Pulp molding products were originally used as commodities. The lining material of the inner packaging has the advantages of low manufacturing cost, good protection performance for goods, no pollution to the environment, and recyclable utilization. It is a typical green packaging. As a packaging product, its application range is quite wide, and can be used for disposable tableware, Packaging of fresh eggs, fruits, flowers, crops, glass products, ceramic products, electronic products, handicrafts, medical equipment, mechanical equipment parts and oth...

AI Technical Summary

Problems solved by technology

[0003] The materials and preparation methods of the current three-dimensional recycled pulp molded products do not match well, and the process of removing impurities from the pulp is paid less attention. Only some particles in the pulp are taken out, and plastics such as inks and tapes are not treated. The later coloring and structural stability of the paper plastic, and the paper plastic is easy to be hydrophilic after molding, and it is easy to rot and deform. Because it is made of paper fibers, its surface is not smooth enough and beautiful.
