Abstract
A paper pulp additive for manufacturing packing paper container is prepared from aluminium sulfate, rosin, caustic soda, sorbic acid and pectine. If it is added to paper pulp, the obtained packing paper container features high water-proof, moisture-proof, leak-proof, and oil-proof properties and high durability. Said packing container includes fast food box, fruit or medicine tray, teaware tray, etc.
Description
The present invention relates to a kind of pulp additive that packaging paper container is used of making.
The present invention in the past, disposable packaging container in the catering industry use, adopt plastic foam product mostly, can't recycling after this kind goods use, not only pollute surrounding environment after abandoning and human body is worked the mischief, also to even go up a century and could degrade gradually if abandon in the ground through decades, even degraded also is to have destroyed soil property, and be unfavorable for the growth in crops, therefore China plans to eliminate gradually in 2000 this pollution, with nontoxic, free of contamination packaging paper container replaces the blister pack container, but directly adopt by straw, the paper pulp that straw and alfa break into is made its packing container, its waterproof, moistureproof, grease proofing and sturdy and durable performance does not reach qualified index again, and can not satisfy market and user's needs.
Purpose of the present invention is intended to overcome above-mentioned defective, the pulp additive that provides a kind of making packaging paper container with protection against the tide, waterproof, leakproof, grease proofing and sturdy and durable readily degradable energy to use.
The objective of the invention is to realize: a kind ofly make the pulp additive that packaging paper container is used with following scheme, the additive that adds in the paper pulp is formulated by aluminum sulfate, rosin, caustic soda, sorbic acid, tartaric acid, its each constituent content is (percentage by weight): aluminum sulfate 28-50%, rosin 7-10%, caustic soda 5-10%, sorbic acid 26-35% and tartaric acid 12-17%.Paper pulp and additives ratio are 90-100: 1.
The utility model has the advantages that: in paper pulp owing to added the aluminum sulfate that plays the moisture proof effect, rosin with sturdy and durable performance, the sorbic acid of waterproof leakproof and the tartaric acid of oil preventing performance make that the packing container of making is the needs that market and consumer have been satisfied in pollution abatement again.
Below in conjunction with embodiment in detail the present invention is described in detail:
Embodiment 1, at first 40% aluminum sulfate, 7% rosin, 8% caustic soda are joined and be heated to 100 ℃ in the high-pressure cylinder, the slurries that are creamy white stir after three kinds of raw material fusings, add 30% sorbic acid again, join after 15% tartaric acid stirs and stir into cotton-shapedly in the paper pulp that straw, straw and alfa break into, and the ratio of additive and paper pulp is promptly to can be used for make the raw material of packaging paper container and fast food and drink box at 1: 100.
The present invention not only is applied to the raw material of fast food and drink box, but also can be widely used in electronics industry package packing supplies raw materials such as making fruit holder, medicine holder, tea set holder, television set holder.
Claims (2)
1, a kind ofly make the pulp additive that packaging paper container is used, it has paper pulp, it is characterized in that: the additive that adds in the paper pulp is formulated by aluminum sulfate, rosin, caustic soda, sorbic acid, tartaric acid, and its paper pulp and additive formula are 90-100: 1.
