Embodiment Construction
[0024] Put the natural zeolite and bentonite into the planetary ball mill at a mass ratio of 3:1, pass through a 50-mesh sieve after ball milling to obtain a mixed solid, and put the mixed solid and hydrochloric acid with a mass fraction of 10-13% into a beaker at a mass ratio of 1:5 , mixed and stirred with a stirrer at a speed of 500-550r / min for 80-100min to obtain a mixed slurry; in parts by weight, weigh 8-12 parts of mixed slurry, 0.3-0.6 parts of sodium chloride, 1.5-1.8 parts Ferric sulfate and 3 to 4 parts of acetic acid solution with a mass fraction of 30 to 40% were put into a three-necked flask, and the three-necked flask was placed in an ultrasonic oscillator, and ultrasonically oscillated for 50 to 70 minutes at an oscillation frequency of 30 to 32 kHz. Place the three-neck flask in a water bath with a water bath temperature of 80-90°C, boil it in water at a constant temperature for 4-6 hours, filter to obtain the filter residue after boiling, wash it with absolut...

Abstract
The invention relates to a preparation method of high-strength impregnated paper and belongs to the technical field of preparation of paper products. The preparation method comprises the following steps: taking zeolite and bentonite as raw materials to prepare filter dreg; taking corn straws as raw materials to prepare a filter cake; then mixing the filter cake, aluminum chloride and copper chloride to obtain a reaction product; and finally, mixing and stirring the reaction product and the filter dreg to obtain a mixed product and carrying out hot pressing to obtain the high-strength impregnated paper. According to the preparation method provided by the invention, the zeolite and the bentonite are mixed and are immersed with hydrochloric acid, so that the specific surface area of the zeolite and the bentonite is increased; copper ions are used for separating out iron ions and sodium, potassium, barium and calcium ions in the zeolite and the bentonite, so that the specific surface areais enlarged and the mechanical properties are also improved; plant fibers are softened and organic acid is generated, so that the mechanical properties of fiber components are improved; a silicon element in the fiber components of the straws is separated out and is combined with generated components including silicon dioxide, silicon carbide and the like, so that the strength and toughness of theimpregnated paper are improved; and the high-strength impregnated paper has a wide application prospect.
Description
technical field [0001] The invention relates to a method for preparing high-strength impregnated paper, which belongs to the technical field of paper product preparation. Background technique [0002] Impregnated paper is a porous material made of interwoven fibers with many spaces between the fibers and filled with air. The production method of the impregnated paper is mainly to impregnate the paper with one or both of urea-formaldehyde resin glue, melamine formaldehyde resin glue and phenolic resin glue. Impregnated paper has super absorbent and anti-solvent ability, and is widely used in cabinets, wardrobes and composite floor veneers. [0003] In the traditional technology, the production process of impregnated paper is as follows: put the qualified impregnated base paper rolls on the paper holder of the impregnated drying production line, and put the qualified melamine impregnated resin into the impregnated tank and the glue storage tank respectively. The paper end is...
