Description
Technical field
The present invention relates to coating, in particular it relates to a kind of waterproof paper bag and preparation method thereof.
Background technology
Food bag i.e. for containing the bag of food, divides from material, including paper foodstuff bag and
Food-packaging bag.Food-packaging bag has mechanical property, anticorrosion and the waterproof characteristic of excellence, but
Food-packaging bag is difficult to decompose, and does not meets the theory of environmental protection instantly；And paper foodstuff bag is owing to having
Excellent degradability, complies fully with the requirement of environmental protection, therefore, it is possible to used on a large scale.
Although paper foodstuff bag has the degradability of excellence, but the mechanical performance of food bag relatively plastics are eaten
For product bag poor, especially water resistance, thus cause paper foodstuff bag in use to occur breaking
Split and meet the generation of the damaged situation of water, significantly limit and further promote and use.
Summary of the invention
It is an object of the invention to provide a kind of waterproof paper bag and preparation method thereof, by preventing that the method prepares
Water paper has mechanical performance and the water resistance of excellence.
To achieve these goals, the invention provides the preparation method of a kind of waterproof paper bag, including:
1) dilute sulfuric acid and starch are carried out gelatinizing to make starch solution；
2) starch solution is carried out steaming and decocting with prepared pastel；
3) by glycerol, salicylic acid, ethanol, Colophonium, coalescents, lignocellulose, Technique of Nano Pd,
Silicon latex, magnesium oxide, surfactant and described pastel are mixed to prepare water-repellent paint；
4) surface that water-repellent paint is painted on paper bag body prepares waterproof paper bag.
Present invention also offers a kind of waterproof paper bag, this waterproof paper bag is prepared from by above-mentioned method.
By technique scheme, the external coating of the waterproof paper bag that the present invention provides has water-repellent paint, should
In water-repellent paint, each component makes this water-repellent paint can stably be attached to paper bag by synergism
The surface of paper bag body and then the mechanical performance of raising paper bag, simultaneously because the primary raw material of paper bag body is
Cellulose, the macromolecular polysaccharide being made up of glucose, the hydroxyl on polysaccharide surface is polar group, lives in surface
The polar group (hydrophilic group) of property agent can combine with hydroxyl, and the non-polar group of surfactant
(hydrophobic group) is consistent outwardly, because hydrophobic group is little with the affinity of water, and then is prevented from water entrance paper
Bag, so that paper bag has reached waterproof performance.
Other features and advantages of the present invention will be described in detail in detailed description of the invention part subsequently.
