Abstract

The invention discloses a high-finishing degree waterproof molded pulp product and a preparation process thereof. The preparation process comprises the following steps: preparing bamboo fiber slurry,boiling raw bamboos in boiling water for 1-2 hours, carrying out disintegration and grinding so as to obtain bamboo fibers, selecting the 200-400-mesh bamboo fibers, adding water which is 2-3 times ofweight of the bamboo fibers, and stirring, so as to obtain slurry; adding 25-35 parts of an adhesive, 0.5-0.7 part of a waterproof agent and / or 0.1-0.3 part of an oil-proof agent, 0.5-0.8 part of ananionic emulsifier and 0.5-0.8 part of titanium dioxide, and mixing, so as to obtain a paper pulp suspension liquid; and introducing the paper pulp suspension liquid into a molding machine, and carrying out dehydration and hot-pressing formation, so as to obtain the molded product. The invention provides the high-finishing degree waterproof molded pulp product which is wide in application prospects, environment-friendly, waterproof and easy to be degraded and the preparation process of the product.

Description

technical field [0001] The invention relates to the field of pulp molding, in particular to a high-gloss waterproof pulp molding product and a preparation process thereof. Background technique [0002] In recent years, with the increasing demand for manufacturing products, especially for outer packaging manufacturing products, the immature manufacturing process has also brought corresponding environmental problems, and people's growing awareness of environmental protection has made technicians In-depth research on the manufacture of renewable resources. [0003] Traditional pulp molding products are mostly used to make paper tableware, fruit and egg trays, and lining cushioning materials for product packaging instead of plastic. For the outer packaging of products with high appearance requirements, traditional materials such as plastics and iron boxes are still used, which are not environmentally friendly and costly. In the field of papermaking, the surface properties of p...
