Problems solved by technology

[0003] However, as far as the safety of paper tableware is concerned, investigations and tests have shown that: "PE" coating is traditionally used to prevent oil from current paper tableware. Waterproof, the amount of reagent used is large, and the operation is inconvenient. It is easy to leak when used in an environment of -30°C-100°C, and harmful substances will be released, which brings hidden dangers of unsafe food to consumers.

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] refer to figure 1 , an oil-proof processing method for plant fiber molded products, comprising the following steps: a. Brooming 100: dissolving plant fibers in water, and fully buffing the plant fibers through hydraulic rotation and stirring, so that the plant fibers themselves are full of micronization Burrs; b. Fusion 200: Fully dissolve the oil-repellent agent in the solution of plant fibers, so that the oil-repellent ions are fully and evenly attached to the burrs of the plant fibers after brooming; c. Adsorption 300: Stir evenly and absorb water Finally, the plant fiber is evenly adsorbed on the forming mold; d, shaping 400: finally, the plant fiber is shaped and solidified on the mold by high temperature and high pressure.

[0016] In order to ensure its oil-repelling effect, the described oil-repelling agent is polyfluorinated. And in step b, ...

Abstract

The invention discloses an oil-proof processing method for plant fiber molded products. Plant fibers are processed by processing methods of brooming, fusion, adsorption and setting, a safety oil technology taking do-fluoride-substituted acid aqueous dispersoids as oil-proof agents is adopted, the plant fibers are guaranteed to be oil-proof and less prone to leakage when used under thenvironment of -30-100 DEG C by setting at the temperature of 200-230 DEG C and under the high pressure of 3.5-4.5 Kg, consumption of the oil-proof agents of the multi-fluoride-substituted acid water dispersoids is small in processing, processing operation is facilitated, and safety in use is guaranteed for consumers as no harmful substance is released.

Description

technical field [0001] The invention relates to an oil-proof processing method for plant fiber molded products of paper tableware. Background technique [0002] Paper products have been widely used in food packaging, especially in the field of disposable food packaging and tableware, because of their renewable raw materials, convenient printing, easy recycling after disposal, and easy degradation. Therefore, the hygienic and safety performance of paper product packaging It should arouse the attention of the government and consumers. As a very important consumer product, disposable paper tableware has penetrated into thousands of households, such as instant noodle bowls, milk tea cups, disposable drinking cups, disposable paper bowls and other products. Banks, shops, airplanes, trains, ships, offices, etc. have paper tableware in almost all places that need to drink water and eat. Even in the homes of most consumers, the original ceramics and glasses are replaced by paper cu...
