The invention discloses a flame-retardant and antibacterial composite polypropylene filter material and a preparation method thereof. The filter material comprises the following components by weight percentage, 70-90 wt% of isotactic polypropylene and 3-10 wt% of functional anion release Materials, 3-10 wt% nano antibacterial agent, 2-5 wt% graphene oxide, 0.5-5 wt% flame retardant and 1-3 wt% dispersant. The filter material of the present invention can be prepared into various forms such as mesh or fabric through melt blending and extrusion, and is suitable for the removal of pollutants in the air in different environments. The functional anion releasing material adopts piezoelectric material, which can spontaneously generate Oxygen ions do not consume energy, do not produce secondary pollution such as ozone, and the released negative oxygen ions coagulate and settle with positively charged particles in the air, which can quickly remove particles; the combination of two or more flame retardants can improve For the flame retardant performance of the material, graphene oxide is used as a conductive modifier, which can not only enhance the negative ion release ability of the piezoelectric material, but also complement the antibacterial effect with the nano antibacterial agent.

The invention relates to an edible mushroom packaging material, and belongs to the technical field of packaging materials. The edible mushroom packaging material is prepared in the following steps: preparing water lettuce fibers from water lettuce leaves by virtue of steaming, acid extraction, alkaline extraction and the like, dissolving carboxymethyl chitosan and xanthan gum in water, mixing withmethanol to obtain a mixed solution, modifying the water lettuce fibers by utilizing laccase, enabling the modified water lettuce fibers and the mixed solution to react, concentrating after the reaction, mixing the obtained concentrated solution with montmorillonite, sorbitol and succinylated monoglycerides to obtain a viscous solution, performing defoaming, film blowing and cutting to obtain theedible mushroom packaging material. The edible mushroom packaging material prepared by the invention not only can inhibit the breeding of harmful bacteria to enable the decomposition effect of ediblemushroom to be in a minimum state, and prolong the fresh-keeping storage time, but the formed packaging material has a microporous structure, so that the water loss can be effectively retarded, the good cell morphology can be kept, and the use is convenient and safe.

The invention discloses a bacteriostatic type cellulose / polypropylene composite material and a preparation method, relates to a cellulose / polypropylene composite material and a preparation method, andaims to solve the problem that the bacteriostatic effect is not ideal as an existing bacteriostatic agent is added into a wood-plastic composite material. The composite material is prepared from cellulose, polypropylene resin, a bacteriostatic agent, a compatilizer, a coupling agent, an antioxidant, a dispersant and a multihole dielectric material. The method comprises the following steps: I, weighing the materials; II, adding the coupling agent into an ethanol solution to obtain a hydrolyzed coupling agent, adding the bacteriostatic agent into the hydrolyzed coupling agent for stirring and drying, so as to obtain a bacteriostatic agent compound, adding the bacteriostatic agent compound, polypropylene resin A, the antioxidant and the dispersant into a double-screw extruder, and performinggranulation and drying, so as to obtain bacteriostatic master batch; III, adding the bacteriostatic master batch, the cellulose, the polypropylene resin B, the compatilizer and the multihole dielectric material into the double-screw extruder, performing granulation and drying to obtain composite granules, and performing injection molding to obtain the bacteriostatic type cellulose / polypropylene composite material. The bacteriostatic type cellulose / polypropylene composite material is applied to the field of wood-plastic composite materials.

The invention provides a sugar cane preliming pressing technique which comprises the following steps: a) crushing: crushing the sugar cane raw material to obtain a crushed sugar cane material; b) sugar cane material liming: spraying lime milk into the crushed sugar cane material to regulate the pH value of the sugar cane material, and uniformly mixing to obtain a lime-milk-mixed crushed sugar cane material, wherein the quantity of the lime milk sprayed into the crushed sugar cane material enables the pH value of the initially pressed juice to be 8-8.5; and c) cane juice liming: pressing the lime-milk-mixed crushed sugar cane material to obtain juice, and adding lime milk into the cane juice to regulate the pH value to 10.5-11. The progressive liming technique can enhance the pressing liming reaction effect, and also gives consideration to the disinfection and sterilization in the pressing stage. The technique promotes the improvement of the product quality, lowers the microbial transformation loss, and enhances the recovery of sugar.
